Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a flowchart of a location sharing method according to an embodiment of the present invention, applied to a first mobile terminal, as shown in fig. 1, where the method includes the following steps:

step 101, establishing communication connection with a target signal source under the condition that the target signal source is searched.

In the embodiment of the invention, the first mobile terminal can search whether a signal source exists nearby or not, and can determine a signal source as a target signal source from the signal source under the condition that the signal source is searched, so that the position of the second mobile terminal relative to the first mobile terminal is obtained through the target signal source, and further position sharing is realized with the second mobile terminal.

The target signal source can be a nearby signal source which can simultaneously cover the first mobile terminal and the second mobile terminal, and can be a signal source with nearby signal strength stronger than that of both terminals, so that the target signal source can acquire the positions of both terminals in real time and send the positions to both terminals; the signal source may be a base station, a wireless router, a mobile terminal, or other device capable of transmitting a signal.

In this step, in the case that the target signal source is searched, a communication connection may be established with the target signal source, so that signal transmission may be subsequently performed with the target signal source, and the target signal source may know the position information of the first mobile terminal relative to itself through the signal transmission direction and the transmission signal strength with the first mobile terminal.

It should be noted that, in the case that an available target signal source is not searched, a prompt message may be output to prompt the user that a signal source meeting the condition is not searched in the current location, location sharing cannot be performed, and the location of the first mobile terminal needs to be moved or changed.

Optionally, before the step 101, the method further includes:

searching at least one signal source by using a target frequency band, wherein the at least one signal source can establish communication connection with the second mobile terminal, and the target frequency band is a frequency band appointed with the second mobile terminal;

and determining a target signal source from the at least one signal source by referring to first signal strength information and second signal strength information, wherein the first signal strength information comprises the signal strength of each signal source in the at least one signal source relative to the first mobile terminal, and the second signal strength information comprises the signal strength of each signal source in the at least one signal source relative to the second mobile terminal.

In this embodiment, in order to ensure that the first mobile terminal and the second mobile terminal can perform location sharing by connecting a target signal source having relatively strong signal strengths to both parties, and ensure the continuity and reliability of the location sharing process, when the location sharing is to be initiated, both parties may agree to use the same frequency band to search nearby signal sources, so as to avoid that the same signal source searched by using different frequency bands exhibits inaccurate signal strengths due to different signal attenuation degrees in different frequency bands. More accurately, the two parties can also agree to use the same channel in the same frequency band to search the signal source.

And under the condition that the first mobile terminal and the second mobile terminal do not have effective networks, the first mobile terminal and the second mobile terminal can mutually transfer the appointed search frequency band by communicating with the base station.

The at least one signal source may be a signal source that can both cover the first mobile terminal and the second mobile terminal, that is, the at least one signal source is a signal source that can be searched by both the first mobile terminal and the second mobile terminal.

After the at least one signal source is searched, the signal strength of each signal source in the at least one signal source relative to the first mobile terminal may also be obtained respectively, specifically, the signal strength information may be obtained by receiving the transmission signal of each signal source through the transceiver of the first mobile terminal, detecting the power of the received transmission signal through the signal detection unit, and converting the power into a signal strength value to obtain the signal strength of each signal source relative to the first mobile terminal.

For the signal strength of each signal source in the at least one signal source relative to the second mobile terminal, after the second mobile terminal determines the signal strength of each signal source relative to the second mobile terminal in the manner described above, the signal strength of each signal source relative to the second mobile terminal may be reported to the target signal source, and then the target signal source forwards the signal strength to the first mobile terminal, or the second mobile terminal may directly send the signal strength of each signal source relative to the second mobile terminal, so as to obtain the second signal strength information.

In the above-mentioned determining, with reference to the first signal strength information and the second signal strength information, a target signal source from the at least one signal source may have multiple implementation manners, for example, according to the first signal strength information and the second signal strength information, a signal source stronger than the signal strengths of the first mobile terminal and the second mobile terminal in the at least one signal source may be determined as the target signal source, specifically, for each signal source in the at least one signal source, a total signal strength of the signal source may be calculated by taking an average value or a weighted value of the signal strength of the signal source relative to the first mobile terminal and the signal strength of the signal source relative to the second mobile terminal, and then a signal source with a highest total signal strength in the at least one signal source is taken as the target signal source; or determining, as the target signal source, a signal source in the at least one signal source, where the signal strength of the signal source relative to the first mobile terminal and the second mobile terminal both exceed a preset strength threshold.

And 102, receiving the relative position information of the first mobile terminal and the second mobile terminal sent by the target signal source, wherein the second mobile terminal is in communication connection with the target signal source.

In the embodiment of the present invention, the target signal source may further establish a communication connection with the second mobile terminal, so that the first mobile terminal and the second mobile terminal can implement location sharing based on the target signal source connected in common.

Taking the target signal source as a base station as an example, when the base station establishes communication connections with both the first mobile terminal and the second mobile terminal, the base station may respectively determine first location information of the first mobile terminal relative to the base station and second location information of the second mobile terminal relative to the base station, where the location information includes a direction and a distance. Specifically, the direction and distance of the first mobile terminal relative to the base station may be determined by a signal transmission parameter with the first mobile terminal, and the direction and distance of the second mobile terminal relative to the base station may be determined by a signal transmission parameter with the second mobile terminal.

More specifically, the direction of the first mobile terminal relative to the base station may be determined based on an antenna angle of the first mobile terminal when the base station performs signal transmission with the first mobile terminal; for example, based on an antenna array directivity variation principle (e.g., a beamforming principle), the antenna angle of the first mobile terminal may be determined by the pointing direction of the antenna when the first mobile terminal receives the transmission signal of the target signal source, so as to obtain the direction of the first mobile terminal relative to the base station, where when the first mobile terminal receives the transmission signal of the target signal source, and when the antenna of the first mobile terminal is aligned with the target signal source, the strength of the received transmission signal of the target signal source is the greatest, so that the antenna angle of the first mobile terminal may be determined according to the pointing direction of the antenna at this time.

And further, based on the signal transmission speed and the transmission duration between the base station and the first mobile terminal, the distance between the first mobile terminal and the base station may be calculated, and for example, the distance between the first mobile terminal and the base station may be obtained by multiplying the signal transmission speed between the base station and the first mobile terminal by the transmission duration, where the signal transmission speed may be obtained by obtaining propagation speeds of electromagnetic waves in different media, and the transmission duration may be determined according to a difference between a signal transmission time when the base station transmits a signal to the first mobile terminal and a signal reception time when the first mobile terminal receives the signal transmitted by the base station.

Similarly, the direction of the second mobile terminal relative to the base station may be determined based on the antenna angle of the second mobile terminal when the base station is in signal transmission with the second mobile terminal; for example, based on an antenna array directivity variation principle (e.g., a beamforming principle), the antenna angle of the second mobile terminal may be determined by the pointing direction of the antenna when the second mobile terminal receives the transmission signal of the target signal source, so as to obtain the direction of the second mobile terminal relative to the base station, where when the second mobile terminal receives the transmission signal of the target signal source, and when the antenna of the second mobile terminal is aligned with the target signal source, the strength of the received transmission signal of the target signal source is the greatest, so that the antenna angle of the second mobile terminal may be determined according to the pointing direction of the antenna at this time.

And further, based on the signal transmission speed and the transmission duration between the base station and the second mobile terminal, the distance between the second mobile terminal and the base station may be calculated, and for example, the distance between the second mobile terminal and the base station may be obtained by multiplying the signal transmission speed between the base station and the second mobile terminal by the transmission duration, where the signal transmission speed may be obtained by obtaining propagation speeds of electromagnetic waves in different media, and the transmission duration may be determined according to a difference between a signal transmission time when the base station transmits a signal to the second mobile terminal and a signal reception time when the second mobile terminal receives the signal transmitted by the base station.

After the base station determines first location information of the first mobile terminal relative to the base station and second location information of the second mobile terminal relative to the base station, the relative location information of the first mobile terminal and the second mobile terminal may be determined according to the first location information and the second location information, and specifically, the location of the first mobile terminal relative to the base station may be determined according to the first location information and the location of the second mobile terminal relative to the base station may be determined according to the second location information with the location of the base station as a reference location, so that the relative location information of the first mobile terminal and the second mobile terminal, such as what location the first mobile terminal is located at the second mobile terminal and how much distance therebetween, may be determined.

Then, the base station may send the relative location information of the first mobile terminal and the second mobile terminal to the first mobile terminal and the second mobile terminal participating in location sharing, respectively, so that the first mobile terminal may receive the relative location information of the first mobile terminal and the second mobile terminal sent by the target signal source.

Optionally, the step 102 includes:

and under the condition of obtaining the position authorization of the second mobile terminal, receiving the relative position information of the first mobile terminal and the second mobile terminal, which is sent by the target signal source.

In this embodiment, in order to ensure information security in location sharing, before the first mobile terminal prepares to perform location sharing with the second mobile terminal, the first mobile terminal may first request the second mobile terminal to obtain location authorization, or grant the second mobile terminal with the right to obtain the location of the first mobile terminal, so that both sides can obtain the location of the other side. For example, when the first mobile terminal needs to initiate a location sharing request to the second mobile terminal, the first mobile terminal may actively grant the second mobile terminal the authority to obtain its location, or may initiate a location authorization request to the second mobile terminal to obtain the authority to obtain the location of the second mobile terminal. Under the condition that at least one of the first mobile terminal and the second mobile terminal does not have an effective network, the first mobile terminal and the second mobile terminal can carry out position authorization in a short message sending mode, if a user of the first mobile terminal can send an authorization short message or a short message requesting authorization to the second mobile terminal through the first mobile terminal, the user of the second mobile terminal can send an authorization confirmation short message to the first mobile terminal through the second mobile terminal.

Specifically, since the first mobile terminal needs to acquire the relative location information between the first mobile terminal and the second mobile terminal through the target signal source, the location authorization information between the first mobile terminal and the second mobile terminal may be reported to the target signal source, so that the target signal source sends the relative location information between the first mobile terminal and the second mobile terminal to the two terminals having the location acquisition right according to the location authorization information.

And 103, displaying the position of the first mobile terminal and the position of the second mobile terminal on a position sharing interface according to the relative position information.

After the relative position information is obtained, the position of the first mobile terminal and the position of the second mobile terminal can be displayed on a position sharing interface, so that a user can visually check the relative distance and direction with another user through the position sharing interface, and can meet with the other user according to the position information displayed on the position sharing interface.

Specifically, a base point position may be specified on the location sharing interface as the location of the first mobile terminal itself, and then the location of the second mobile terminal on the location sharing interface may be determined according to the direction and distance of the second mobile terminal relative to the first mobile terminal, which are indicated in the relative location information. For example, if it is indicated that the second mobile terminal is located at an angle of 30 degrees in the south-east direction of the first mobile terminal according to the relative position information and the distance is 500 meters, the central position may be indicated as the position of the first mobile terminal itself on the position sharing interface, and a target point may be determined as the indicated position of the second mobile terminal according to the ruler distance on a straight line where the angle of the lower right side on the position sharing interface with respect to the central position is minus 30 degrees.

Optionally, the step 102 includes:

receiving first relative position information and second relative position information sent by the target signal source, wherein the first relative position information is position information of the first mobile terminal relative to the target signal source, and the second relative position information is position information of the second mobile terminal relative to the target signal source;

the step 103 comprises:

and displaying the position of the target signal source, the position of the first mobile terminal and the position of the second mobile terminal on a position sharing interface according to the first relative position information and the second relative position information.

In this embodiment, in order to enable a user to intuitively obtain a relative position relationship among the target signal source, the first mobile terminal, and the second mobile terminal, the target signal source may send, to the first mobile terminal, position information (i.e., first relative position information) of the first mobile terminal with respect to the target signal source and position information (i.e., second relative position information) of the second mobile terminal with respect to the target signal source, so that the first mobile terminal may display, on a position sharing interface, a position of the target signal source, a position of the first mobile terminal, and a position of the second mobile terminal according to the first relative position information and the second relative position information.

Specifically, a base point position may be designated on the location sharing interface as the location of the target signal source, then the location of the first mobile terminal on the location sharing interface is determined according to the direction and distance, relative to the target signal source, of the first mobile terminal indicated in the first relative location information, and the location of the second mobile terminal on the location sharing interface is determined according to the direction and distance, relative to the target signal source, of the second mobile terminal indicated in the second relative location information, so as to obtain the locations of the target signal source, the first mobile terminal, and the second mobile terminal on the location sharing interface.

For example, if the first mobile terminal is indicated to be located at an angle of 30 degrees in the south-east direction of the target signal source according to the first relative position information, and the distance is 500 meters, a central position may be indicated as the position where the target signal source is located on the position sharing interface, and a first target point may be determined as the indicated position of the first mobile terminal according to a ruler distance on a straight line where an angle of minus 30 degrees with respect to the central position is located at the lower right on the position sharing interface; if the second mobile terminal is indicated to be positioned at an angle of 45 degrees in the southwest of the target signal source according to the second relative position information and the distance is 300 meters, a second target point can be determined as the schematic position of the second mobile terminal according to the ruler distance on a straight line, where the angle of the left lower side of the position sharing interface relative to the center position is minus 135 degrees.

Therefore, the position of the target signal source, the position of the first mobile terminal and the position of the second mobile terminal are displayed on the position sharing interface, so that a user can visually see the position of the second mobile terminal and the position of the target signal source, and the user can approach to the position of the second mobile terminal and the position of the target signal source according to the position sharing information on the position sharing interface, so that the position sharing method is more flexible.

Optionally, at least one of the following items is further displayed on the location sharing interface:

the relative distance between the first mobile terminal and the target signal source;

the relative distance between the second mobile terminal and the target signal source;

and the first mobile terminal and the second mobile terminal form an included angle relative to the target signal source.

In this embodiment, in order to enable a user to more clearly and intuitively view the position relationship among the first mobile terminal, the second mobile terminal, and the target signal source, the relative distance between the first mobile terminal and the target signal source, the relative distance between the second mobile terminal and the target signal source, and the included angle between the first mobile terminal and the second mobile terminal relative to the target signal source may be displayed on the position sharing interface, and the included angle may be understood as an included angle between a connection line between the first mobile terminal and the target signal source and a connection line between the second mobile terminal and the target signal source.

For example, as shown in fig. 2, not only the position O of the target base station, the position a of the first mobile terminal and the position B of the second mobile terminal, but also the relative distance r1 between the target base station and the first mobile terminal, the relative distance r2 between the target base station and the second mobile terminal, and the angle between the first mobile terminal and the second mobile terminal (i.e. the angle between OA and OB) relative to the target signal source are displayed on the position sharing interface 20

Therefore, the user can more accurately and quickly determine the relative distance and the direction with the opposite side through the relevant position information displayed on the position sharing interface, and further can share and navigate according to the position to realize quick meeting.

Optionally, after the step 102, the method further includes at least one of:

and displaying a spherical coordinate system in a second preset area of the position sharing interface, wherein the spherical coordinate position information of the first mobile terminal, the spherical coordinate position information of the second mobile terminal and the spherical coordinate position information of the target signal source are indicated on the spherical coordinate system.

In this embodiment, in order to show the location sharing information to the user more comprehensively and in detail, more related location information of the first mobile terminal and the second mobile terminal may be displayed in different forms on the location sharing interface.

Specifically, the relative position information may be displayed in a first preset area of the position sharing interface in a text form, and the relative position information may include any one or more of the following items: an included angle between the first mobile terminal and the second mobile terminal relative to the target signal source is, for example, 60 degrees, an azimuth of the second mobile terminal relative to the first mobile terminal is, for example, southeast, a distance between the first mobile terminal and the target signal source is, for example, 200 meters, a distance between the second mobile terminal and the target signal source is, for example, 300 meters, a signal strength of the target signal source is, for example, a signal strength is strong or a signal strength value is displayed, and the like.

Or displaying the spherical coordinate position information of the first mobile terminal, the second mobile terminal and the target signal source in a spherical coordinate form in a second preset area of the position sharing interface, specifically, establishing a spherical coordinate system by taking the position of the target signal source as the center, then respectively determining the positions of the first mobile terminal and the second mobile terminal on the spherical coordinate system according to the first position information of the first mobile terminal relative to the base station and the second position information of the second mobile terminal relative to the base station, and may transmit the spherical coordinate system to the first mobile terminal and the second mobile terminal respectively, the spherical coordinate system may indicate spherical coordinate position information of the first mobile terminal, spherical coordinate position information of the second mobile terminal, and spherical coordinate position information of the base station.

Referring to fig. 3, taking a base station as an example, a spherical coordinate system 30 may be established with a location O of the base station as a center, and a plane in which the base station and a first mobile terminal are located is taken as a horizontal plane xy, a coordinate position a of the first mobile terminal on the spherical coordinate system 30 is determined according to a direction and a distance of the first mobile terminal relative to the base station, and a coordinate position B of a second mobile terminal on the spherical coordinate system 30 is determined according to a direction and a distance of the second mobile terminal relative to the base station, as shown in fig. 3, a distance from the first mobile terminal to the base station is r1, a distance from the second mobile terminal to the base station is r2, and an included angle between the first mobile terminal and the second mobile terminal relative to the base station on the horizontal plane is

The height of the second mobile terminal relative to the horizontal plane of the base station and the first mobile terminal can be represented by an included angle theta between OB and the z axis, wherein theta is smaller than 90 degrees and represents that the second mobile terminal is above the first mobile terminal, and theta is larger than 90 degrees and represents that the second mobile terminal is below the first mobile terminal.

After receiving the spherical coordinate system, the first mobile terminal can display the spherical coordinate system in a second preset area of the position sharing interface, so that a user can visually and stereoscopically view the directions of the first mobile terminal, the second mobile terminal and the target signal source through the spherical coordinate system in the second preset display area.

The first preset area and the second preset area can be any area on the position sharing interface, and in order to ensure the attractiveness and the visual effect of the interface, an area for displaying the relative position information and the spherical coordinate system can be respectively preset at the lower left corner and the lower right corner of the position sharing interface.

In this embodiment, when the target signal source is capable of determining its own geographical location, the target signal source may determine geographical location information of the first mobile terminal on a map according to a distance and a direction of the first mobile terminal from the target signal source, and similarly, may also determine geographical location information of the second mobile terminal on the map according to a distance and a direction of the second mobile terminal from the target signal source.

The target signal source can directly send the geographical position information of the first mobile terminal and the geographical position information of the second mobile terminal to the first mobile terminal and the second mobile terminal, so that the position sharing parties can check the geographical positions of the first mobile terminal and the second mobile terminal; the first mobile terminal can load a position sharing map interface according to the geographical position information of the first mobile terminal and the second mobile terminal, and the geographical position information of the first mobile terminal and the geographical position information of the second mobile terminal are displayed on the interface, and the geographical position information of the target signal source can also be displayed.
