The terms "first," "second," and the like, are used below for descriptive purposes only and are not to be construed as implying or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature, and in the description of embodiments of the application, unless otherwise indicated, the meaning of "a plurality" is two or more.

The term "User Interface (UI)" in the following embodiments of the present application is a media interface for interaction and information exchange between an application program or an operating system and a user, which enables conversion between an internal form of information and a form acceptable to the user. The user interface is a source code written in a specific computer language such as java, extensible markup language (extensible markup language, XML) and the like, and the interface source code is analyzed and rendered on the electronic equipment to finally be presented as content which can be identified by a user. A commonly used presentation form of the user interface is a graphical user interface (graphic user interface, GUI), which refers to a user interface related to computer operations that is displayed in a graphical manner. It may be a visual interface element of text, icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, widgets, etc., displayed in a display of the electronic device.

In order to accomplish the positioning of the electronic device, there are two positioning modes:

1) Network positioning

Network positioning includes base station positioning and WiFi positioning. The base station positioning is a positioning system based on cellular mobile communication technology, and is mainly used for calculating the approximate position of the electronic equipment based on the communication time difference between the base station and the electronic equipment. The WiFi positioning is realized by detecting the ID (router address) of WiFi and then completing positioning under the cooperation of a WiFi position database and a map database.

In general, network positioning is mainly based on the position of a wireless access point or a base station, which has a high positioning speed, but has a large positioning error, and needs to be able to perform positioning under the networking condition.

2) Global positioning system (Global Positioning System, GPS) positioning

GPS positioning is to estimate the distance between a satellite and an electronic device by receiving satellite signals and the propagation time of the signals, so as to determine the position of the electronic device.

In general, GPS positioning is mainly based on the position of satellites, its positioning result is accurate, and networking is not required, but its positioning speed is slow.

Although the electronic device can acquire the position information of the electronic device by using the two modes, starting the electronic device to position can increase the power consumption of the electronic device, when the electric quantity of the electronic device is low, the two modes are not beneficial to saving the electric quantity of the electronic device, the standby time of the electronic device is prolonged, and when the configuration of the electronic device is low, the positioning capability of the electronic device is weak, which may cause inaccurate positioning results. Therefore, how to complete the positioning of the electronic device and improve the positioning effect of the electronic device is a current urgent problem to be solved.

The embodiment of the application provides a positioning method, which relates to a master device and a slave device, wherein the master device can acquire the positioning capability of the master device and/or the slave device, and when the master device triggers a positioning service, the positioning capability is used for indicating the positioning effect of the electronic device according to the positioning capability of the master device and/or the slave device, when the positioning effect of the master device is better, the master device starts positioning to acquire the position information of the master device, when the positioning effect of the slave device is better, the master device initiates a positioning request to the slave device, acquires the position information of the slave device, and finally the master device uses the position information to finish the positioning service.

The number of the main devices can be one, the number of the auxiliary devices can be one or more, and the main device can determine the optimal positioning device from the plurality of devices according to the positioning capability of each device, so that the positioning effect of the devices is improved as much as possible.

The positioning capability may include, but is not limited to, one or more of the following: the power, the charge state, the positioning mode, the positioning overhead, the load condition, the equipment type, the starting state of the positioning function, the screen off state, the positioning state, the distance, the network identification and the like. Positioning effects may include, but are not limited to: positioning speed, positioning accuracy, positioning loss, etc. Specifically, the master device may determine a positioning effect of each device according to a positioning capability of each device, and rank each device according to the positioning effect, where the device with a better positioning effect ranks higher, and the master device may select location information of the device ranked higher when performing positioning. For example, with the positioning loss as the positioning effect, the master device may determine the positioning loss through the charging state and the positioning overhead of each device, and when the device is in the charging state and the positioning loss is smaller, the positioning loss of the device is smaller, and the ranking of the device is higher. A specific description of the positioning capabilities and positioning effects can be found in the subsequent method embodiments, which are not first developed here.

Therefore, when a plurality of electronic devices coexist, the main device can combine the positioning capability of other electronic devices, select the most suitable electronic device to execute positioning, the positioning effect of the electronic device is improved as much as possible, the cost of the main device when executing positioning service is reduced, for example, when the duration requirement of the main device is higher, the main device can acquire the position information of the auxiliary device when starting positioning, the duration capability of the main device is improved when the positioning service is finished, or when the main device needs to acquire the position information of network positioning and does not have or does not support the network positioning capability at present, the main device can acquire the position information of the auxiliary device when starting network positioning, and the main device is ensured to finish the service as much as possible.

Fig. 1 illustrates a communication system 1000 provided by an embodiment of the present application.

As shown in fig. 1, the communication system 1000 may include: master device 1001 and slave device 1002. Wherein the number of master devices 1001 is one, and the number of slave devices 1002 may be one or more. Illustratively, in the communication system 1000 shown in fig. 1, the number of master devices 1001 and slave devices 1002 is one. Wherein:

the master device 1001 is a device that needs to acquire position information. Specifically, master device 1001 may be configured to initiate a capability negotiation request to slave device 100, obtain the positioning capabilities of slave device 1002, and determine the device that initiated the positioning based on the positioning capabilities of master device 1001 and slave device 1002. When the slave device 1002 is a device that needs to initiate positioning, the master device 1001 is further configured to send a positioning request to the slave device 1002, obtain location information of the slave device 1002, and when the master device 1001 is a device that needs to initiate positioning, the master device 1001 initiates positioning, and obtain location information of the master device 1001. In addition, the master device 1001 may also be used to perform a positioning service according to the location information. For a description of the master device 1001 determining a device that initiates positioning according to positioning capabilities, reference will be made to the following, which is not first developed.

The slave device 1002 is a device that provides location information. Specifically, the slave device 1002 may be configured to receive a capability negotiation request sent by the master device 1001, send its own positioning capability to the master device 1001, receive a positioning request of the master device 1001, initiate positioning according to the positioning request, obtain location information, and send the location information to the master device 1001.

In addition, the communication connection between the master device 1001 and the slave device 1002 may be a wired connection or a wireless connection. The master device 1001 may send a capability negotiation request to the slave device 1002 based on the communication connection, obtain the positioning capability of the slave device 1002, send a positioning request to the slave device 1002, obtain the position information of the slave device 1002, and so on. The wireless connection may be a close range connection such as a high fidelity wireless communication (wireless fidelity, wi-Fi) connection, a bluetooth connection, an infrared connection, an NFC connection, a ZigBee connection, or a remote connection including, but not limited to, a remote connection of a mobile network based on 2g,3g,4g,5g, and subsequent standard protocols. For example, master device 1001 and slave device 1002 may log onto the same user account (e.g., hua as an account) and then make a remote connection through a server.

Fig. 2 shows a flow chart of a positioning method according to an embodiment of the present application.

As shown in fig. 2, the positioning method may include:

s101, the master device acquires a service request.

The service request is used for requesting to acquire the location information of the main device, and executing a service according to the location information, where the service may refer to a function related to the location information of the device in an application installed on the main device, and the main device may satisfy a user's requirement by executing the service, for example, the service may refer to displaying weather, pushing nearby news, navigating, and the like, where the service needs to acquire the location information of the main device to complete.

The master device obtaining the service request may include the following two cases:

1) The master device detects a user operation, and obtains a service request in response to the operation

The user operation can be used for triggering the service, and the master device can start to execute the service according to the user operation, namely, the service request is generated, and the position information of the master device is requested to be acquired. Specifically, the user operation may refer to a touch operation acting on the main device, for example, a click operation acting on an application program displayed in the main device, or may refer to a voice operation acting on the main device, for example, a voice instruction of a user to input "open a navigation application", or the like, which is not limited by the embodiment of the present application. In the embodiment of the present application, the user operation may also be referred to as a first operation. The service triggered by the first operation may also be referred to as a first service.

3A-3B illustrate some user interfaces involved when a master device detects a user operation to obtain a service request.

FIG. 3A illustrates an exemplary user interface 10 on a host device for an application menu, which may be referred to as the host interface of the host device.

As shown in fig. 3A, the user interface 10 may include: status bar 101, calendar indicator 102, weather indicator 103, settings icon 104, browser icon 105. Wherein:

the status bar 101 may include one or more signal strength indicators of a mobile communication signal, one or more signal strength indicators of a wireless fidelity (WiFi) signal, a battery status indicator, and a time indicator. Calendar indicator 102 may be used to indicate the current time. Weather indicator 103 may be used to indicate a weather type.

As shown in fig. 3A, the host device may detect a user operation on the browser icon 105, for example, a click operation on the browser icon 105, and in response to the operation, the host device opens the browser application, displays the user interface 20 shown in fig. 3B, where the user interface 20 is a user interface provided by the browser application, and in fig. 3B, the user interface 20 may be a main page of the browser application.

As shown in fig. 3B, the user interface 20 is used to display a search portal of the browser application, a search keyword, and information recommended by the browser application according to the location information. The user interface 20 may include a news display area 201, where the news display area 201 is configured to display nearby news searched according to location information of the host device when the browser application starts the nearby news pushing function.

That is, when the main device detects a user operation and opens the browser application, since the opening of the browser application starts a nearby news pushing function, the function needs to acquire the location information of the main device to be normally executed, so after detecting the operation of opening the browser application by the user, the main device generates a service request for requesting to acquire the location information of the main device, so that the browser application can normally execute the news pushing function according to the location information, and the main device can display nearby news searched according to the location information when displaying the user interface 20.

In addition, in the process that the host device acquires the location information and acquires the news according to the location information, the host device may display a prompt 201A as shown in fig. 3B in the user interface 20, the prompt 201A being used to prompt the user that the host device is acquiring the location information and acquiring the news according to the location information.

It will be appreciated that, not limited to the above operation of opening a browser and triggering the operation of obtaining a service request, in other embodiments of the present application, the host device may also receive other operations, such as an operation acting on a navigation application, a weather application, etc., and the embodiments of the present application are not limited thereto.

2) The master device automatically obtains the service request

The master device may automatically obtain the service request when it detects that the preset condition is satisfied. Specifically, the master device may periodically acquire the service request at a specified time or interval, for example, the master device may periodically update the location information of the master device for 10 minutes, so the master device may automatically acquire the service request every 10 minutes.

It can be understood that, the method is not limited to the above two cases of triggering and acquiring service requests, and the embodiment of the application does not limit the time for triggering and acquiring service requests by the master device.

S102, the main equipment acquires the positioning capability of the main equipment.

The positioning capability of the master device is used to characterize the positioning effect of the master device. The positioning capability may include, but is not limited to: power, state of charge, positioning capability, positioning overhead, load conditions, device type, on state of positioning function, off screen state, positioning state, network identification, etc.

The power refers to the current remaining power of the electronic device, for example, 10% of the power remains in the main device. When the electric quantity of the main device is smaller, the electric quantity loss of the main device when the main device starts positioning is required to be considered, and when the electric quantity of the main device is smaller than 5%, the main device can acquire the position information of the auxiliary device through the auxiliary device starting positioning when the electric quantity of the main device is needed, so that the position information can be acquired by the main device according to the position information, and the electric quantity consumption when the main device starts positioning is avoided.

The charging state includes both charged and uncharged states. When the main equipment is in a charging state currently, the fact that the electric quantity loss of the main equipment is not considered currently is indicated, and when the position information is needed, the main equipment can be directly started to acquire the position information of the main equipment.

The positioning modes can include, but are not limited to, network positioning and GPS positioning, when the main device comprises the network positioning mode, the main device can complete positioning by using the network positioning mode, and when the main device comprises the GPS positioning mode, the main device can complete positioning by using the GPS positioning mode. The main device can determine which mode of positioning the main device specifically needs to start according to the service of the main device, for example, when the main device currently has position information which needs to be accurate by one service, the main device can start GPS positioning to acquire the accurate position information acquired by the GPS positioning. The description of network positioning and GPS positioning can be found in the foregoing, and will not be repeated here. In addition, it should be noted that the master device does not include a network positioning manner, which may mean that hardware of the master device does not support network positioning, or that the master device does not currently open network positioning, and similarly, the master device does not include a GPS positioning manner, which may mean that hardware of the master device does not support GPS positioning, or that the master device does not currently open GPS positioning.

The positioning overhead is used to represent the power consumption overhead of the electronic device when the electronic device is turned on for positioning. For example, an overhead level may be defined for positioning overhead, where the power consumption overhead of the device is different at different levels, and the higher the level, the greater the power consumption overhead of the electronic device when the device turns on positioning.

The load situation refers to the load situation of the current operation of the device, wherein the load situation of the electronic device may be determined by the central processing unit (central processing unit, CPU) usage, memory usage or system throughput (Transactions Per Second, TPS). For example, the load capacity of the electronic device may be divided into a plurality of load classes according to the CPU usage rate, the memory usage rate or the TPS of the electronic device, where the load classes are different, the load of the electronic device is different, the higher the load class is, the greater the load of the electronic device is, the heavier the work of the current electronic device is, the lower the load class is, the smaller the load of the electronic device is, and the current electronic device is idle. In other words, a less loaded electronic device is more suitable for start-up positioning than a more loaded electronic device.

The device type may be used to indicate whether the electronic device is a power sensitive device, where a power sensitive device is a device that has a greater limit on power consumption than a device that is not power sensitive. For example, for a device with sufficient electric power, the loss of power has a small influence on the normal operation of the device, and the device may be referred to as a non-power sensitive device. That is, since the positioning causes a loss of power, the non-power sensitive device can start positioning, and the power sensitive device is not suitable to start positioning.

The on state of the positioning function comprises two states of an on positioning function and an off positioning function. Compared with the state that the main equipment is in the positioning function not started, when the main equipment is in the positioning function started state, the position information can be acquired more quickly, and the execution of the service is completed. Thus, the master device may determine whether to initiate positioning using the master device in conjunction with the on state of the positioning function.

The screen-off state comprises two states of screen-off and screen-on. When the main equipment is in the screen-off state, all applications of the main equipment are in the background running state, the power consumption of the main equipment is small, when the main equipment is in the screen-on state, the main equipment is possibly in the state of running the applications in the foreground, at the moment, the system resources of the main equipment are occupied, and the starting positioning occupies the system resources of the main equipment, so that the power consumption is caused, and therefore, the main equipment can be combined with the screen-off state to determine whether the main equipment is used for starting the positioning.

The location status may be used to indicate whether the master device is currently initiating a location fix, obtaining location information. When the master device is currently initiating positioning to obtain location information, the master device may directly use the current location information to perform the service without combining the positioning capabilities of other devices to determine the positioning device.

Positioning effects may include, but are not limited to: positioning speed, positioning accuracy, positioning loss, etc. The positioning speed refers to the time required for completing positioning, the positioning accuracy refers to the accuracy of the obtained position information, and the positioning loss refers to the loss degree of power caused by starting positioning. The positioning speed of the main device may be determined according to the electric quantity, the positioning manner and the load condition of the main device, specifically, when the electric quantity of the device is larger, the positioning capability is network positioning and the load is smaller, the positioning speed of the device is faster, the positioning loss of the device may be determined according to the charging state and the positioning overhead of the device, specifically, when the device is in the charging state and the positioning overhead is smaller, the positioning loss of the device is smaller. Therefore, when the positioning effects are different, the positioning capabilities to be considered are different, and the positioning effects required by the main equipment can be specifically combined, and then the positioning effects of the equipment are determined according to the positioning capabilities associated with the positioning effects.

The master device may trigger acquisition of the positioning capabilities of the master device in several cases:

1) After the main equipment acquires the service request, triggering and acquiring the positioning capability of the main equipment

That is, the master device may trigger acquisition of the positioning capability of the master device when it detects that the position information needs to be acquired, so that the master device may determine whether to initiate positioning according to the positioning capability of the master device.

2) After receiving user operation, the main equipment triggers and acquires the positioning capability of the main equipment

That is, the master device may display a prompt message to prompt the user whether to acquire the positioning capability of the master device, and trigger to acquire the positioning capability of the master device after receiving the approval of the user to acquire the positioning capability of the master device, or the master device may provide a positioning switch, trigger to start the positioning operation after receiving the action of the user on the positioning switch, and trigger to acquire the positioning capability of the master device.

4A-4B illustrate some of the user interfaces involved in activating a position switch by a master device.

Fig. 4A illustrates a main interface of a main device, namely, a user interface 10, and a detailed description of the user interface 10 can be referred to in fig. 3A, which is not repeated herein.

As shown in fig. 4A, the host device may detect a user operation to slide down, display a window 106 as shown in fig. 4B on the user interface 10, the window 106 for displaying one or more shortcut switches through which a user may quickly turn on one or more functions, such as WiFi, bluetooth, flashlight, flight mode, etc.

As shown in fig. 4B, the window 106 may include a control 106A, which control 106A may accept user operations (e.g., touch operations, click operations) to turn on/off the co-location function. The presentation of control 106A can include icons and/or text (e.g., text "locate", "co-locate", "multi-device locate", "distributed locate", etc.). When the master device detects a user operation acting on the control 106A, that is, detects a user operation for starting the co-location function, the master device may start the location function, that is, obtain location capabilities of itself and other devices, determine a device for starting location according to the location capabilities, and control the device to start location, so as to obtain location information. In some embodiments, the host device, upon detecting a user operation on control 106A, may alter the display form of control 106A, such as adding shadows when control 106A is displayed, as shown in FIG. 4B.

It will be appreciated that, without limitation to the above-mentioned receipt of a slide down operation in fig. 4A, window 106 may be displayed, and the host device may also display window 106 via other user interfaces, such as those provided by an application, to which embodiments of the present application are not limited.

As can be seen from fig. 4A-4B, the master device may provide a positioning control, and the user may control whether the master device obtains positioning capabilities of the respective devices by controlling the opening and closing of the control, and control the positioning of the devices according to the positioning capabilities.

In the embodiment of the application, the positioning control can also be called a first control, the user interface displayed by the master device and containing the first control can also be called a second user interface, and the user operation acted on the first control by the user can also be called a second operation, and the second operation is used for triggering to acquire the positioning capability of the master device and/or the slave device and executing the service.

3) Periodic acquisition by a master device

That is, the master device may automatically and periodically update the positioning capability of the master device, so as to ensure the accuracy of the positioning capability of the master device when the master device starts the execution of the service.

It can be understood that the above mentioned three cases of triggering to obtain the positioning capability of the master device are not limited, for example, the master device may also trigger to obtain its positioning capability when turning on or on a screen, which is not limited by the embodiment of the present application.

It can be seen that, the execution sequence of step S101 and step S102 is not limited in the embodiment of the present application, the master device may acquire the positioning capability of the master device when acquiring the service request, or may acquire the positioning capability of the master device when acquiring the service request.

S103, the master device judges whether the master device is a positioning device according to the positioning capability of the master device.

The positioning device is the electronic device with the best positioning effect, and is also the device for finally starting positioning.

In the embodiment of the application, after the positioning capability of the main equipment is obtained, the main equipment can directly judge whether the main equipment can directly start positioning according to the positioning capability of the main equipment, and obtain the position information of the main equipment, so that the service is executed according to the position information of the main equipment.

That is, when the positioning effect of the master device is good, the master device is a positioning device. This is because if the positioning effect of the master device itself is good, the master device can choose the device that initiates the positioning from the master device and the slave devices without combining the positioning capability of the slave devices. Therefore, the speed of executing the service by the main equipment can be increased, and the most accurate position information can be obtained while the positioning effect is met. For example, when positioning loss is used as a positioning effect, if the main device is currently in a charging state, the main device directly initiates positioning and cannot cause the influence of electric quantity loss, and at the moment, the positioning loss when the main device initiates positioning is smaller, the main device can directly initiate positioning and acquire the position information of the main device.

In addition, when the positioning effect of the main equipment is not good, the main equipment can be further combined with the positioning capability of other equipment to select the equipment which is most suitable for initiating positioning from the equipment.

The determining that the positioning effect of the device is determined according to whether the positioning capability of the device meets a preset condition, wherein the determining that the positioning capability of the device meets the preset condition specifically comprises: the positioning capabilities of the device reach a threshold value and/or the positioning capabilities of the device match a preset capability, etc. For example, the power is higher than 50%, the device type is non-power sensitive, etc.

Therefore, when the master device determines that the master device is a positioning device according to the positioning capability of the master device, step S112 is performed, otherwise step S104 is performed.

It should be noted that step S103 is an optional step, and the master device may directly acquire the positioning capabilities of the plurality of devices, and combine the positioning capabilities of the plurality of devices to select the positioning device from them.

S104, the master device discovers the slave device.

The slave device refers to an electronic device located near the master device, and the description of the slave device may be referred to in detail and will not be repeated here.

Wherein the master device may discover the slave device through one or more wireless communication technologies of a communication module, e.g., bluetooth, wiFi, NFC, etc. Preferably, the master device may discover an electronic device located near the master device through bluetooth, which may further reduce power consumption of the master device when performing the positioning service, since bluetooth has a smaller power consumption of the master device.

In some embodiments, the host device may initiate one or more of WLAN, bluetooth, or NFC in the wireless communication module to discover electronic devices in the vicinity of the host device in response to user operation by the user to initiate the co-location function. The description of the co-location function may be referred to in detail with respect to fig. 4A-4B, and will not be repeated here.

In other embodiments, the master device may trigger discovery of electronic devices in the vicinity of the master device after the service request is obtained.

S105, the master device sends a capability negotiation request to the slave device.

After the master device discovers the slave device, the master device may send a capability negotiation request to the slave device, the capability negotiation request requesting acquisition of the positioning capability of the slave device. Preferably, the master device may perform capability negotiation with the slave device based on bluetooth low energy, reducing power consumption of the master device.

S106, the slave device obtains the positioning capability of the slave device.

The positioning capabilities of the slave device are used to characterize the positioning effect of the slave device. The positioning capability may include, but is not limited to: the power, the charge state, the positioning mode, the positioning overhead, the load condition, the equipment type, the starting state of the positioning function, the screen off state, the positioning state, the distance, the network identification and the like. The descriptions of the electric quantity, the charging state, the positioning mode, the positioning overhead, the load condition, the device type, the on state, the off state, and the positioning state in the positioning capability may refer to the related descriptions of the positioning capability of the main device in step S102, which are not repeated herein. In addition, the distance refers to a distance between the slave device and the master device, and when the positioning effect includes positioning accuracy, the master device may determine the positioning device using a distance between the slave device and the master device as a positioning capability of the slave device, since the further the distance is, the larger an error of the position information of the slave device as the position information of the master device is. The network identifier may refer to a local area network identifier, where the local area network identifier is used to indicate whether the master device and the slave device are in the same local area network, and when the slave device and the master device are in the same local area network, the higher the communication efficiency between the master device and the slave device is, the more reliable the communication between the master device and the slave device is.

It can be seen that the positioning capabilities that the slave device needs to acquire and the positioning capabilities that the master device needs to acquire may be the same or different. For example, the positioning capability of the master device may include a device type, and the positioning capability of the slave device may not include a device type, so that when the master device determines the positioning device according to the positioning capability of each device, the master device may preferentially determine whether the master device may be directly determined as the positioning device according to the device type of the master device, if the device type of the master device is non-power sensitive, the master device may directly start positioning, without determining the positioning effect of other devices, so as to shorten the positioning time, otherwise, the master device may determine the positioning effect of each device in combination with other positioning capabilities of each device, such as positioning overhead, electric quantity, and the like.

S107. the slave returns the positioning capability of the slave to the master.

At this time, the master device may obtain the positioning capabilities of the master device and the slave device. For example, the master device may establish a location capability information table, store the location capability of each device in the location capability information table, and periodically update and maintain the location capability information table, so as to ensure the accuracy of the information in the location capability table. In addition, when the master device acquires the positioning request again, if the positioning capability information table already stores the positioning capability of one slave device, the master device may not acquire the positioning capability of the slave device any more.

It will be appreciated that when there are multiple slaves, the master may send a capability negotiation request to multiple slaves, acquiring the positioning capabilities of the multiple slaves.

In some embodiments, after the master device obtains the positioning capability of each device, the devices meeting the requirements may be further screened out according to the positioning capability of each device. This is because some devices may not have a positioning function and cannot acquire location information, so the master device does not need to waste system resources to calculate the positioning effect of the devices, and the master device can remove the devices from the positioning capability information table. Or further, because the service request initiated by the master device may need the location information acquired by different locating modes, the master device may further screen out the devices meeting the requirements according to the locating modes of each device, for example, when the master device needs the location information of network locating, the master device may screen out the devices containing the locating modes of network locating according to the locating capability of each device, and when the master device needs the location information of GPS locating, the master device may screen out the devices containing the locating modes of GPS locating according to the locating capability of each device.

S108, the master device determines the positioning device according to the positioning capabilities of the master device and the slave device and the positioning strategy.

Specifically, the main device may determine the positioning effect of each device according to the positioning policy in combination with the positioning capability of each device, and select the positioning device with the best positioning effect from the positioning effects, and the main device may respond to the service request of the main device by using the position information acquired by the positioning device, so as to complete the service of the main device.

That is, when a service request exists, the master device determines the positioning device for starting positioning from a plurality of devices including the master device and the slave device, so that the positioning effect of the plurality of devices is improved as much as possible, and the service execution effect of the master device is improved.

In an embodiment of the present application, the positioning strategy may include, but is not limited to, the following two types:

1) Setting different ratios for different positioning capacities, and calculating the numerical value representing the positioning effect in a summation mode

That is, different ratios may be set according to the degree of association of the positioning capability with the positioning effect. Taking the positioning effect of the main device as an example of the positioning speed, assuming that the degree of association between the electric quantity, the positioning capability and the load condition of the electronic device and the positioning speed is gradually reduced, that is, the electric quantity of the electronic device affects the positioning speed of the device most easily, the positioning capability is second, the load condition is minimum, the ratio of the electric quantity, the positioning capability and the load condition can be set to 3, 2 and 1, the main device can substitute the respective positioning capability of the device and the ratio corresponding to the respective positioning capability into the following formula 1, and calculate the numerical value corresponding to the positioning effect of the respective device:

Positioning effect = positioning capability 1 x ratio 1+ positioning capability 2 x ratio 2+ … … + positioning capability N x ratio N formula 1

Therefore, the calculation formula for the positioning effect of each device can be obtained as follows: the electric quantity is 3+positioning capability is 2+load condition is 1, wherein the electric quantity, the positioning capability and the load condition can be preprocessed into corresponding numerical values respectively. It can be seen that the larger the corresponding value of the positioning effect is, the better the positioning effect of the electronic equipment is.

That is, the master device may select an electronic device having the largest or smallest value of the positioning effect as the positioning device. Specifically, when the positioning effect of the electronic device with the largest value is the best, the electronic device with the largest value can be selected as the positioning device, and when the positioning effect of the electronic device with the smallest value is the best, the electronic device with the smallest value can be selected as the positioning device.

It can be seen that the positioning device is determined by summing the ratios of the positioning capabilities, so that the positioning effects of the devices can be determined more accurately by comprehensively considering the positioning capabilities of the devices.

2) Setting different priority levels for different positioning capabilities, wherein the positioning effect of equipment which preferentially meets the preset capability is best

When the electronic device preferentially meets the requirement of a certain positioning capability, the positioning effect of the electronic device can be preferentially determined to be the best. Taking the positioning effect of the main equipment as an example of positioning loss, when the main equipment is in a charging state, the main equipment in the charging state can offset the power loss caused by positioning through charging, so that the positioning effect of the main equipment can be considered to be best, and the main equipment can directly start positioning to acquire position information without considering other positioning capabilities or the positioning effects of other equipment. Or further, when each device is not in a charging state or a plurality of devices are in a charging state, the positioning device can be further determined by combining other positioning capabilities, such as positioning cost, for example, when the positioning cost of the slave device is minimum, the slave device can be determined to be the device with the best positioning effect.

It can be seen that the positioning device is determined according to the device which preferably satisfies the preset capability, so that the positioning speed can be increased, and the master device can respond to the service request as soon as possible to complete the execution of the service.

In general, the master device may determine the positioning effect of the device by determining whether the positioning capability of the device satisfies a preset condition, and further, the master device may determine the positioning device by comparing the positioning capability of each device or the degree of matching with the preset condition.

For example, it may be preferentially determined whether the positioning capability of one device (master device or slave device) satisfies a preset condition. When the positioning capability of the main equipment meets a first condition, the main equipment is positioning equipment; and when the positioning capability of the slave device meets the second condition, the slave device is a positioning device. Alternatively, further, a location device may be determined in conjunction with location capabilities between multiple devices. When the positioning capability of the master device meets a first condition and the positioning capability of the slave device does not meet a second condition, the master device is the positioning device; and when the positioning capability of the master device does not meet the first condition and the positioning capability of the slave device meets the second condition, the slave device is the positioning device. The first condition and the second condition may be the same, and at this time, the master device may determine positioning effects of the master device and the slave device according to the same criteria, for example, determine the positioning device according to a positioning manner and a charging state of the master device and the slave device. The first condition and the second condition may also be different, and in this case, the master device may determine the positioning effect of the master device and the slave device according to different standards, for example, determine the positioning device according to the device type, the charging state, and the positioning manner of the master device, and the charging state and the positioning manner of the slave device.

It should be noted that in other embodiments of the present application, other positioning strategies may be included, and embodiments of the present application are not limited in this respect. For example, the positioning device may be determined by combining the above two positioning strategies, and for example, a plurality of devices that preferentially satisfy a certain preset capability may be found first, then the numerical values corresponding to the positioning effects of the plurality of devices are sorted according to the ratio of the positioning capabilities, and the device with the best positioning effect is selected according to the numerical values, and is determined as the positioning device, so that the positioning speed is increased, and the positioning capability of each device is comprehensively considered.

In addition, when there are a plurality of devices with the best positioning effect, the positioning device may be determined by four ways:

1) The main equipment randomly selects one equipment from the equipment with the best positioning effect as positioning equipment;

2) The main equipment selects equipment closest to the main equipment from the equipment with the best positioning effect as positioning equipment, so that the accuracy of the position information can be improved as much as possible;

3) When the plurality of devices with the best positioning effect comprise the main device, the main device is selected as the positioning device, so that the step of sending a positioning request to the slave device by the main device can be reduced, and the speed of executing the service by the main device is increased;

4) The main device selects one device from the devices with the best positioning effect as the positioning device according to the selection of the user, so that the device which is finally positioned can be determined according to the selection of the user, and the operability of the user is improved.

That is, when there are a plurality of devices with the best positioning effect, the master device may determine one or more positioning devices, and when the master device may determine a plurality of positioning devices, the master device may further process the position information collected by the plurality of positioning devices, for example, select the position information with the highest occurrence frequency, so as to determine final position information, or perform fusion processing on the plurality of position information, so as to determine a position located between the plurality of positions. When the master device can determine a plurality of positioning devices, all the devices with the best positioning effect can be determined as positioning devices, or part of the devices with the best positioning effect can be randomly selected from the plurality of devices with the best positioning effect to be used as positioning devices, or the devices with the distance from the master device smaller than a certain threshold range can be selected from the plurality of devices with the best positioning effect to be used as positioning devices, or the plurality of positioning devices can be determined according to the selection of a user, and the embodiment of the application is not limited to the above.

In some embodiments, the master device may determine the location device from the slave devices based solely on the location capabilities of the slave devices and the location policy. At this point, the master device may determine the location device from the one or more slave devices without considering the location capabilities of the master device. Alternatively, when the master device only finds one slave device, the master device may directly acquire the location information of the slave device, that is, when the master device performs step S104, when the slave device only has one device, steps S109 to S111 may be directly performed.

Steps S109-S111 may be performed when the slave device is a positioning device, and step S112 may be performed when the master device is a positioning device.

In addition, after the master device determines the positioning device, different prompt messages can be displayed in the user interface according to whether the positioning device is the master device or the slave device, so that a user can acquire whether the device initiating positioning is the master device or the slave device. Reference may be made to fig. 5A-5B with particular reference to the user interface involved in the master device determining the locating device.

In the process that the host device determines the positioning device and acquires the position information through the positioning device, the host device may display a user interface as shown in (a) or (b) of fig. 5A. Specifically, the master device may display a location identifier 101A as shown in (a) of fig. 5A or a location identifier 101B as shown in (B) of fig. 5A in the status bar 101 of the user interface 20. The location identifier 101A and the location identifier 101B are used to indicate that the current master device is initiating a location function. In addition, the master device may also indicate the device that initiates the positioning currently through the positioning identifier 101A and the positioning identifier 101B. It can be seen from the positioning identifier 101A and the positioning identifier 101B that a distance scale is included below the icon of the positioning identifier 101B, and the icon of the positioning identifier 101B is darker than the icon of the positioning identifier 101A, where the positioning identifier 101A is used for indicating that the master device is a positioning device, and the positioning identifier 101B is used for indicating that the slave device is a positioning device. The description of the user interface 20 may be found in detail in the foregoing descriptions of fig. 3A-3B, and will not be repeated here.

Alternatively, when the positioning device is a slave device, the master device may also display the identification of the slave device, such as the device model number, the device type, the device name, and the like, on the left side of the positioning identification 101B as shown in (B) of fig. 5A.

That is, the master device may display a location identifier in the status bar and distinguish the device currently initiating the location by a change in the color, size, shape, etc. of the location identifier.

In the process that the master device determines the positioning device and obtains the position information through the positioning device, when the positioning device is a slave device, the master device may also display prompt information 202 as shown in fig. 5B in the user interface 20. The hint information 202 is used to indicate that the master device is acquiring location information for a slave device having a device name of "HUAWEI 10". Wherein the prompt 202 includes a change option 202A, the change option 202A being usable by a user to trigger an adjustment of a positioning device that initiates positioning. Thus, the user can adjust the equipment for initiating positioning according to the own requirements, and the operability of the user is improved.

It will be appreciated that when the positioning device is the master device itself, the master device may not display a prompt message to prompt the device currently initiating positioning, i.e., display the user interface 20 as shown in fig. 3B.

If the master device determines that the master device is not a positioning device in step S103, or further, after determining that the slave device is a positioning device in step S108, steps S109-S111 may be performed to obtain the position information of the slave device.

S109, when the slave equipment is the positioning equipment, the master equipment sends a positioning request to the slave equipment.

The positioning request is used for triggering the slave device to start positioning and acquiring the position information of the slave device.

In some embodiments, the location request further includes a location mode requested by the master device, because different service requests of the master device may need location information collected by different location modes, and the master device may determine the location mode according to a service corresponding to the service request. For example, when the service executed by the main device is navigation, the most suitable positioning mode of the service is GPS positioning, because accurate position information is required for navigation, the error of the position information acquired by network positioning is large, the service is not applicable, and the GPS positioning is accurate, so that the position information can be acquired by using GPS positioning, and for example, when the service executed by the main device is weather inquiring, the most suitable positioning mode of the service is network positioning, because only approximate position is required for weather inquiring, and the GPS positioning consumes more time compared with the network positioning, so that the position information can be acquired by using network positioning.

S110, starting positioning by the slave equipment, and acquiring position information of the slave equipment.

The location information of the slave device is used to indicate the location of the slave device, and since the slave device is located at a relatively short distance from the master device, the location information of the slave device may be used instead of the location information of the master device, and the master device may use the location information of the slave device when executing the service. The slave device may acquire the location information of the slave device by means of network positioning or GPS positioning. The manner of network positioning or GPS positioning can be referred to in the foregoing, and will not be described in detail herein.

S111, the slave device returns the position information of the slave device to the master device.

That is, the master device may acquire the location information transmitted from the slave device.

If the master device determines that the master device is a positioning device through step S103 or step S108, the master device may execute step S112 to obtain the location information of the master device.

And S112, when the main equipment is positioning equipment, the main equipment starts positioning and acquires the position information of the main equipment.

In some embodiments, the master device may determine a positioning manner of the master device according to a service request of the master device, and further obtain location information of the master device using the positioning manner. This is because the location information collected by different positioning methods may be required for different service requests, and the specific connection between the different services and the positioning methods may be referred to in the related description of step S108, which is not repeated here.

S113, responding to the service request, and executing the service by the main equipment according to the position information.

When the positioning device is a master device, the position information is the position information collected by the master device, and when the positioning device is a slave device, the position information is the position information collected by the slave device. Finally, the main equipment can execute corresponding service according to the position information, and normal execution of the service is ensured. Wherein, the master device performs a service according to the location information, which may mean that the master device displays information related to the location information, including text, picture, video, audio, and the like.

Illustratively, FIG. 5C illustrates a user interface that the host device involves when completing a service after obtaining location information.

As shown in fig. 5C, after the host device obtains the location information, the relevant news related to the location may be searched according to the location information indicated by the location information, and the searched news may be displayed in the news display area 201 in fig. 5C, for example, when the location of the host device is a city, the news display area 201 may display the news 1"A city air temperature warms up" and the news 2"a city is checked out" and the user may view the relevant information of the region where the user is located by browsing the news nearby the news displayed in the news display area 201, so as to learn about the interesting things. In the embodiment of the present application, the user interface shown in fig. 5C may also be referred to as a first user interface, where news information of a city where a master device or a slave device is located is displayed.

In general, the positioning method provided by the embodiment of the application is suitable for a plurality of devices, when one device needs to acquire the position information, the device can combine the positioning capability of surrounding devices to determine the device which initiates positioning finally, so as to achieve different positioning effects, for example, save the power consumption of the device, accelerate the service execution speed of the device, obtain better user experience, and the like.

For a better understanding of the present solution, a detailed procedure for obtaining location information by the master device will be described with reference to a specific flowchart shown in fig. 6.

Suppose there is scenario 1: the user opens the weather application in the bracelet, inquires about the current weather, and a large screen and a mobile phone exist around the bracelet. The positioning capabilities of the wristband, large screen and cell phone are shown in table 1:

TABLE 1

The bracelet is used as a master device, and the large screen and the mobile phone are slave devices, wherein the bracelet is required to acquire the position information acquired by network positioning currently, and inquire weather according to the position information. At this time, the bracelet may generate a service request for inquiring weather based on the operation of opening the weather application by the user, obtain the positioning capability of each device, arrange to obtain the above table 1, and then use the positioning loss as the positioning effect, and the bracelet may obtain the position information according to the following steps S201-S207, where the method includes:

S201, judging whether the main equipment belongs to power sensitive equipment.

After obtaining the service request, the master device can judge whether the master device belongs to the power sensitive device according to the device type of the master device, if so, the master device is indicated to have larger limit on power consumption at present, and is not suitable for positioning, if not, the master device is indicated to have smaller limit on power consumption at present, and even if the positioning can cause the power consumption of the master device, the master device can start positioning.

Step S203 may be performed when the master device belongs to a power sensitive device, otherwise step S202 may be performed.

In scenario 1, it can be seen from table 1 that since the bracelet belongs to a power consumption sensitive device, step S203 is performed after step S201 is performed.

It can be understood that, in addition to determining whether the master device belongs to the power sensitive device to determine whether to use the master device to start positioning, conditions such as whether the master device has positioning capability, and whether the master device has positioning capability are determined to use the master device to start positioning, which are not limited by the embodiment of the present application.

S202, acquiring the position information of the main equipment.

When the main equipment does not belong to the power sensitive equipment, the main equipment can directly start positioning to acquire the position information, so that the service execution efficiency of the main equipment is improved.

S203, ordering the positioning effects of the devices according to the positioning capability of the devices.

When the main equipment belongs to the power sensitive equipment, the main equipment can further combine the positioning capability of each equipment, and the positioning effect of each equipment is calculated by utilizing a positioning strategy. The largest value corresponding to the positioning effect, or the higher the ranking of the device with the most fitting positioning capability and preset capability.

For example, it is possible to set a larger ratio of the positioning capability with respect to the positioning loss, calculate the positioning effect of each device, or determine the device in the charged state as the device having the best positioning effect, or the like.

For a description of determining the positioning effect according to the positioning capability, reference may be made to the related description of step S108, and the description is omitted here.

In scenario 1, in the process of ordering, since the bracelet needs the location information acquired by network positioning, the bracelet can preferentially judge whether the equipment supporting network positioning exists according to the positioning mode of each equipment. It can be seen from table 1 that the large screen and the mobile phone meet the requirement, and then the positioning effects of the large screen and the mobile phone are further ordered according to the charging states of the large screen and the mobile phone, and it can be seen that the large screen is in the charging state and the mobile phone is in the uncharged state, so that the positioning effect of the large screen is higher than that of the mobile phone.

It should be noted that, when the master device ranks the positioning effects of the devices, each device may include a master device and a slave device, so that the master device may further determine the positioning device from all devices if it is determined that the master device does not satisfy the preliminary condition. Alternatively, each device herein may include only the slave device, so that the master device may directly exclude the master device and determine the positioning device among the slave devices in the case where it is determined that the master device does not satisfy the condition.

S204, judging whether a plurality of devices with the best positioning effect exist.

The master device can find out the device with the best positioning effect according to the ordering of the positioning effects of the devices, wherein the positioning effect of the device is better when the ranking is higher. Wherein steps S205-S206 may be performed when there are a plurality of devices with the best positioning effect at the same time, and step S207 may be performed when there is only one device with the best positioning effect.

In the scene 1, the positioning effects of the large screen are best only as can be seen by sequencing according to the positioning capabilities of the bracelet, the large screen and the mobile phone.

S205, acquiring the position information of the devices with the best positioning effect.

The master device may send a positioning request to the devices with the best positioning effects at the same time, to request to acquire the position information acquired by the devices with the best positioning effects.

S206, further processing the plurality of position information to obtain final position information.

The master device may find the most accurate or most accurate location information from the acquired plurality of location information as final location information. For example, the position information having the highest frequency of occurrence is found out from the plurality of position information as the final position information. Alternatively, the master device may randomly select one location information from the plurality of location information as the final location information. The embodiment of the present application does not limit the process.

S207, acquiring the position information of the equipment with the best positioning effect.

That is, when there is only one device with the best positioning effect, the master device may directly acquire the position information acquired after the device starts positioning.

In the scene 1, the bracelet can acquire position information acquired by the large screen, finally, the bracelet can acquire weather according to the position information, and the queried weather condition is displayed in the display screen through weather application.

As can be seen from steps S201 to S207, the master device may dynamically adjust the device that initiates positioning according to the positioning capability of each device, so as to ensure that the best positioning effect is obtained.

It should be noted that the above steps S201 to S207 are only one specific example listed for the sake of understanding the present solution, and do not constitute limitation of the embodiments of the present application, and the embodiments of the present application mainly surround the idea of selecting a device from which positioning is finally completed according to the positioning capabilities of a plurality of devices, and thus other solutions developed around the idea fall within the scope of the embodiments of the present application.
