The middle layer program in the embodiment of the present invention is located between the kernel and the framework layer, interacts with the kernel and the framework layer, and is mainly used for determining and storing routing policies of a plurality of applications, implementing a network management method, and the like.

The application layer program, application for short, interacts with the middle layer program through the framework layer program. For ease of understanding, the following may take the form of omitting the framework layer procedures.

The intelligent device in the embodiment of the invention stores various data, including: identification related to a plurality of applications, routing policy of each application, network mutual exclusion policy and the like. Preferably, these data may be stored in the middle layer.

APP (Application) represents an Application of an Application layer; frame layers are not shown; a connectivity manager program or service belonging to the middle tier program; the APP interacts with a connectivity manager; mark APP is stored in the middle layer and represents information such as an identifier related to the APP received and stored by the connectivity manager; the configrule is stored in the middle layer and represents information such as the routing policy of the APP and the network mutual exclusion policy, which are determined and stored by the connectivity manager. kernel represents a kernel, and contains rtwifi, rtlte, rtzigbee and rtblue to respectively represent the routing of a WiFi network, an LTE network, a Zigbee network and a bluetooth network; WIFI, LTE, ZIGBEE, and BLUETOOTH denote a WIFI local area network, an LTE network, a ZIGBEE network, and a BLUETOOTH network, respectively. The connectivity manager can interact with rtwifi, rtlte, rtzigbee or rtblue, and correspondingly accesses to a WiFi local area network, an LTE network, a Zigbee network and a Bluetooth network.

The method for determining the network mutual exclusion policy in the present invention is described below. Preferably, the network mutual exclusion policy may be determined by an intermediate layer program (e.g., connectivity manager) in the embodiment of the present invention.

Preferably, information such as frequency ranges of various networks and information such as frequency ranges of each frequency band in the network can be collected in advance. For example, the frequency ranges of the frequency bands of the LTE network, the frequency ranges of the WiFi local area network 2.4G (mega) frequency band and the 5G frequency band, the frequency range of the 2.4G frequency band of the Zigbee network, and the like are collected.

And for the frequency bands of any two networks, determining whether the frequency range overlapped between the frequency bands of the two networks exceeds a preset repetition frequency range threshold value. The repetition frequency range threshold may be predetermined based on experimental data, empirical data, historical data, and/or actual conditions.

When the overlapped frequency range between the frequency bands of the two networks exceeds a preset re-frequency range threshold value, determining that the frequency bands of the two networks are mutually exclusive, namely, only allowing the frequency band of one of the frequency bands of the two networks to be usable or allocable at the same time.

For example, for the 2.4G band of the WiFi local area network and the 2.4G band of the Zigbee network, the two are mutually exclusive, and only the 2.4G band of the WiFi local area network or the 2.4G band of the Zigbee network is allowed to be used or allocated at the same time.

When the overlapping frequency range between the frequency bands of the two networks does not exceed the preset re-frequency range threshold, determining that the frequency bands of the two networks can coexist, namely allowing the frequency bands of the two networks to be used or to be distributed at the same time.

For example, for a 5G band of a WiFi local area network and a 2.4G band of a Zigbee network, both may coexist, and the 5G band of the WiFi local area network and the 2.4G band of the Zigbee network are allowed to be used or both may be allocated at the same time.

Thereby obtaining the network mutual exclusion strategy of the embodiment of the invention. The network mutual exclusion policy may include: at least one set of mutually exclusive network frequency bands and only one frequency band in each set of mutually exclusive network frequency bands is allowed to be used or allocated. In the frequency bands of each mutually exclusive network group, the frequency range of the overlapping frequency bands of any two networks exceeds the threshold value of the repetition frequency range. For example, the mutually exclusive network bands include a 2.4G band of a WiFi local area network and a 2.4G band of a Zigbee network.

Preferably, the middle layer program (e.g., connectivity manager) determines the network mutual exclusion policy and stores the determined network mutual exclusion policy in the middle layer.

In the embodiment of the invention, the applied routing policy comprises at least one network which the application has the right to use, the priority of each network and the priority of each corresponding route. The applied routing policy further comprises: the priority of each network that the application has access to.

The following specifically describes a method for determining a routing policy applied in the embodiment of the present invention. Preferably, the routing policy of each application may be determined by an intermediate layer program (e.g., connectivity manager). A flow chart of a method for determining a routing policy applied in the embodiment of the present invention is shown in fig. 3, and includes the following steps:

s301: and when receiving a network authority application request of the application, determining at least one network applied by the application.

Preferably, the application sends a network permission application request to a middle tier program (e.g., connectivity manager) during the installation process. The network authority application request of the application comprises at least one network applied by the application.

Preferably, each application sends a network permission application request to the connectivity manager of the middle layer through a corresponding socket channel. The applied identifiers correspond to the identifiers of the socket channels one to one.

When the middle layer program receives the network authority application request of the application, at least one network applied by the application is analyzed from the network authority application request. For example, the APP1 is resolved for using the 5G band of the WiFi local area network, the LTE network, and the Zigbee network.

The middle layer program generates a unique mark of the application for each application; for example, the socket mark1 of APP1 is given by the UID of APP1 as the only mark of APP 1.

And storing at least one network applied by each application in correspondence with the unique mark of the application. Further, it may be stored in the intermediate layer.

S302: and determining at least one network which the application is authorized to use according to the at least one network applied by the application, the multiple networks supported by the intelligent equipment and a preset network mutual exclusion strategy.

Preferably, the middle layer program detects all networks supported by the intelligent device to which the middle layer program belongs, and obtains a plurality of networks supported by the intelligent device.

Comparing at least one network applied by the application with various networks supported by the intelligent equipment, and screening the network supported by the intelligent equipment from the at least one network applied by the application as at least one network possibly applied by the application.

And determining at least one network which the application is authorized to use from the at least one network which the application may apply for according to the network mutual exclusion strategy.

For example, at least one network that an application may apply to includes: a 2.4G frequency band of a WiFi local area network, a 5G frequency band of the WiFi local area network, a specified frequency band of an LTE network and a 2.4G frequency band of a Zigbee network; and the appointed frequency band of the LTE network and the frequency bands of other networks can coexist, and mutual exclusion does not occur. Determining at least one network which is authorized to be used by the application according to the network mutual exclusion strategy, wherein the network can be a 2.4G frequency band of a WiFi local area network, a 5G frequency band of the WiFi local area network and an appointed frequency band of an LTE network; or a 5G frequency band of a WiFi local area network, a specified frequency band of an LTE network, and a 2.4G frequency band of a Zigbee network. The specified frequency band of the LTE network may specifically be a frequency band that does not mutually exclusive with the 2.4G frequency band.

S303: a network priority configuration interface is displayed for at least one network to which the application has access.

The middle layer program displays a network priority configuration interface, and displays various networks which the application has the right to use and priority input fields of the various networks in the network priority configuration interface.

Preferably, the middle layer program displays a network priority configuration interface, and displays various networks which the application has the right to use and candidate priorities corresponding to the various networks in the network priority configuration interface.

S304: after the priorities of various networks input by a user are received through the network priority configuration interface, the priorities of various networks which the application is authorized to use are determined.

Preferably, the middle layer program determines the priority of the various networks which the application has the right to use after receiving the priority of the various networks input by the user through the priority input field of the various networks in the network priority configuration interface.

For example, the priority order of the various networks that APP1 is determined to have rights to use is: the 5G frequency band of the WiFi local area network, the designated frequency band of the LTE network and the 2.4G frequency band of the Zigbee network. The specified frequency band of the LTE network may specifically be a frequency band that does not mutually exclusive with the 2.4G frequency band.

Preferably, when the user selects the candidate priorities corresponding to the various networks in the network priority configuration interface, the middle layer program receives a selection instruction of the user for the priorities of the various networks through the network priority configuration interface, and determines the priorities of the various networks which the application has right to use.

For example, the candidate priorities corresponding to the 5G frequency band of the WiFi local area network, the designated frequency band of the LTE network, and the 2.4G frequency band of the Zigbee network in the network priority configuration interface are respectively selected as the first priority, the second priority, and the third priority by the user, then the intermediate layer program receives the priorities respectively selected by the user for the 5G frequency band of the WiFi local area network, the designated frequency band of the LTE network, and the 2.4G frequency band of the Zigbee network through the network priority configuration interface, and determines that the priorities of the 5G frequency band of the WiFi local area network, the designated frequency band of the LTE network, and the 2.4G frequency band of the Zigbee network to which the application is entitled to use are respectively the first priority, the second priority, and the third priority.

S305: and determining the priority of each route corresponding to each network which the application has the right to use.

Preferably, the intermediate layer program determines the priority of each route corresponding to each network that the application has the right to use according to the priority of each network that the application has the right to use. The priorities of the various networks correspond one-to-one with the priorities of the routes corresponding to the various networks.

Further, the order in which the route is used by the label 1 (i.e., APP1) is rt _ wifi > rt _ lte > rt _ zigbee; and the rt _ wifi, the rt _ lte and the rt _ zigbee respectively represent the corresponding routes of the three networks.

In the embodiment of the present invention, each network is configured with a DNS (Domain Name System) file corresponding to the network. For example, the DNS file of a WiFi local area network is WiFi _ resolve. The DNS file of the network comprises DNS information corresponding to the network, and the DNS information comprises a network address of a DNS server corresponding to the network.

The following develops and introduces a network management method in the embodiment of the present invention, and a flow diagram of the method is shown in fig. 4, and the method includes the following steps:

s401: a network-based data transfer request for an application is received.

Preferably, the middle layer program receives a network-based data transmission request of the application through a socket channel corresponding to the application. Further, the data transfer request may include data to be transferred by the application over the network.

S402: and determining the currently allocable network according to the opened network and a preset network mutual exclusion strategy.

Preferably, the middle layer program detects at least one opened network (according to a user instruction or an application request) in the intelligent device to which the middle layer program belongs.

And the middle layer program acquires a predetermined and stored network mutual exclusion strategy.

And determining the currently allocable network according to the opened network and a preset network mutual exclusion strategy. Currently assignable networks may include: a network that is not currently open (in the present smart device).

Further, according to the started network and a preset network mutual exclusion strategy, a current unallocated network is determined, and the current unallocated network is prohibited from being started.

For example, when the 2.4G frequency band of the WiFi local area network that is already turned on in the smart device, but the frequency band that does not mutually exclude the 2.4G frequency band in the LTE network and the 2.4G frequency band of the Zigbee network are not turned on, it is determined that the currently allocable network may include the 2.4G frequency band of the WiFi local area network (that is currently turned on) and the frequency band that does not mutually exclude the 2.4G frequency band in the LTE network (that is not currently turned on) according to the already turned on network and a preset network mutual exclusion policy. The frequency bands in LTE that are not mutually exclusive with the 2.4G frequency band may include the 1880-1890Mhz frequency band in band 39 and/or the frequency band corresponding to band 3. And the 2.4G frequency band of the Zigbee network is determined as a currently unallocated network, and is prohibited from being turned on.

For another example, when the 2.4G frequency band of the WiFi local area network and the 2.4G frequency band of the Zigbee network that have been turned on in the smart device but the frequency band that does not mutually exclude the 2.4G frequency band in the LTE network is not turned on, it is determined that the currently allocable network may include the frequency band that does not mutually exclude the 2.4G frequency band in LTE (currently not turned on) according to the turned on network and a preset network mutual exclusion policy; and determining that the currently allocable network further comprises a 2.4G frequency band of one of a 2.4G frequency band (currently opened) of a WiFi local area network and a 2.4G frequency band (currently opened) of a Zigbee network according to the opened network and a preset network mutual exclusion strategy.

Further, for mutually exclusive frequency bands between different networks, for example, for a 2.4G frequency band of a WiFi local area network and a 2.4G frequency band of a Zigbee network, the frequency band of one of the networks may be selected as a part of a currently assignable network by using the following methods.

First, the frequency band of a network can be randomly selected from mutually exclusive frequency bands among different activated networks to be used as a part of the currently allocable network. And taking the frequency band of the other network which is not selected as the current unallocated network, and forbidding the current unallocated network to be started.

Second, the frequency band of the network that is turned on last (i.e. turned on last on the time axis) can be selected from the mutually exclusive frequency bands among the different networks that have been turned on, as a part of the currently assignable network. The frequency band of other networks which are started previously (i.e. not started last) is taken as the current unallocated network, and the current unallocated network is prohibited from being started.

And thirdly, selecting one of the frequency bands of the networks according to the sources of the opening instructions of the mutually exclusive frequency bands among the different opened networks. For example, when the start command of the frequency band of some networks is from the request of the application itself, and the start command of the frequency band of other networks is from the human-computer interaction interface (i.e. directly input by the user), the frequency band of the network from which the start command is from the human-computer interaction interface (i.e. from the user) is selected as a part of the currently assignable network. And taking the frequency band of the other network with the opening instruction from the application request (namely from the non-user) as the current unallocated network, and forbidding the current unallocated network to be opened.

S403: according to the priorities of various networks in the applied routing strategy, whether each network which the application has the right to use belongs to the currently distributable network is judged step by step; when the presence determination result is yes, step S404 is executed; when the judgment results are no, step S406 is executed.

Preferably, after receiving the network-based data transmission request of the application, the middle layer program determines the routing policy of the application from the pre-stored routing policies of the plurality of applications in the middle layer.

The applied routing policies include: at least one network to which the application is entitled, priorities of various networks to which the application is entitled, and priorities of respective DNS files corresponding to the various networks to which the application is entitled.

And judging whether the network corresponding to the priority belongs to the currently allocable network or not for the network corresponding to each priority which is used by the application according to the sequence of the priorities of the various networks in the applied routing strategy from high to low. When the presence determination result is yes, step S404 is executed; when the judgment results are no, step S406 is executed.

For example, a network to which smart devices are currently assignable includes: the 2.4G frequency band of the WiFi local area network, and the specified frequency band of the LTE network (i.e. the frequency band in the LTE network that does not mutually exclude the 2.4G frequency band). Currently unallocated networks include: the 5G frequency band of the WiFi local area network and the 2.4G frequency band of the Zigbee network. Routing policies of APP1 indicate that APP1 has access to a variety of networks including: a 5G frequency band of the WiFi local area network, a specified frequency band of the LTE network and a 2.4G frequency band of the Zigbee network; the priority of the various networks that APP1 has access to is in order from high to low: the 5G frequency band of the WiFi local area network, the designated frequency band of the LTE network and the 2.4G frequency band of the Zigbee network. The specified frequency band of the LTE network may specifically be a frequency band that does not mutually exclusive with the 2.4G frequency band.

According to the priority sequence from high to low of various networks which the APP1 has the right to use, comparing the 5G frequency band of the WiFi local area network with the APP1 with the highest (or first) priority with the currently allocable network, and judging whether the 5G frequency band of the WiFi local area network belongs to the currently allocable network; and judging that the 5G frequency band of the WiFi local area network does not belong to the currently allocable network. Comparing the assigned frequency band of the APP1 LTE network with the current allocable network, and judging whether the assigned frequency band of the LTE network belongs to the current allocable network; if the specified frequency band of the LTE network is determined to belong to the currently allocable network, that is, if the determination result is yes, step S404 is executed.

For example, a network to which smart devices are currently assignable includes: the 2.4G frequency band of the WiFi local area network, and the specified frequency band of the LTE network (i.e. the frequency band in the LTE network that does not mutually exclude the 2.4G frequency band). Currently unallocated networks include: the 5G frequency band of the WiFi local area network and the 2.4G frequency band of the Zigbee network. The routing policy of the APP2 shows that the priority of various networks of the various networks that the APP2 has the right to use is in the order from high to low: the 2.4G frequency band of the Zigbee network, the 5G frequency band of the WiFi local area network and the designated frequency band of the LTE network. The specified frequency band of the LTE network may specifically be a frequency band that does not mutually exclusive with the 2.4G frequency band.

According to the sequence of high priority to low priority of various networks which the APP2 has right to use, firstly comparing the 2.4G frequency band of the Zigbee network with the APP2 with the highest (or first) priority with the currently allocable network, and judging whether the 2.4G frequency band of the Zigbee network belongs to the currently allocable network; the first judgment result is that the 2.4G frequency band of the Zigbee network does not belong to the currently allocable network. Comparing the APP2 frequency band of 5G of the WiFi local area network with the current allocable network, and judging whether the frequency band of 5G of the WiFi local area network belongs to the current allocable network; and judging that the 5G frequency band of the WiFi local area network does not belong to the currently allocable network according to the second judgment result. Then, comparing the designated frequency band of the LTE network with the APP2, and judging whether the designated frequency band of the LTE network belongs to the currently allocable network; if the third determination result is that the specified frequency band of the LTE network belongs to the currently allocable network, that is, if the determination result is yes, step S404 is executed.

For example, a network to which smart devices are currently assignable includes: the 2.4G frequency band of the WiFi local area network, and the specified frequency band of the LTE network (i.e. the frequency band in the LTE network that does not mutually exclude the 2.4G frequency band). Currently unallocated networks include: the 5G frequency band of the WiFi local area network and the 2.4G frequency band of the Zigbee network. The routing policy of the APP3 shows that the priority of various networks of the various networks that the APP3 has the right to use is in the order from high to low: the 5G frequency band of the WiFi local area network and the 2.4G frequency band of the Zigbee network.

According to the priority sequence from high to low of various networks which the APP3 has the right to use, comparing the 5G frequency band of the WiFi local area network with the APP3 with the highest (or first) priority with the currently allocable network, and judging whether the 5G frequency band of the WiFi local area network belongs to the currently allocable network; the first judgment result is that the 5G frequency band of the WiFi local area network is judged not to belong to the currently allocable network. Comparing the 2.4G frequency band of the Zigbee network with the APP3 with the second highest (or second) priority (actually, the last priority) with the currently allocable network, and determining whether the 2.4G frequency band of the Zigbee network belongs to the currently allocable network; if the second determination result (actually, the last determination result) is that the 2.4G frequency band of the Zigbee network does not belong to the currently assignable network, that is, the determination results are all negative, and step S406 is executed.

S404: and taking the network which is judged to be the involved network as the network which can be currently used by the application.

Specifically, the network involved in the above steps is determined as a result of the determination, and is a network that the application has the right to use and belongs to the currently assignable network.

In this step, preferably, the middle layer program regards the network which the application has the right to use and belongs to the currently assignable network as the currently available network of the application.

S405: and transmitting the data of the application according to the network which is currently used by the application.

In the embodiment of the invention, each network is configured with the DNS file corresponding to the network. The DNS file stores DNS information for the corresponding network, which may include a network address of a DNS server. The DNS file is updated in real time.

Preferably, the middle layer program (e.g., connectivity manager) updates DNS files corresponding to various networks in the smart device in real time. Specifically, the middle layer program monitors the routing information of each network reported by the kernel, and updates the DNS file corresponding to each network. For example, a WiFi local area network corresponds to a DNS file named WiFi _ resolve.

Preferably, the intermediate layer program determines a route and a DNS file corresponding to a network which can be currently used by the application; and transmitting the data of the application according to the route and the DNS file.

Further, the middle layer program analyzes current DNS information (including a network address of a DNS server) from a DNS file corresponding to a network which can be used currently by the application; determining a route corresponding to a network which can be used currently; and transmitting the data to be transmitted through the network, which is related to the data transmission request of the application, according to the routing and the analyzed DNS information.

For example, the data transmission request of APP1 indicates that APP1 needs to access www.bing.com, the connectivity manager parses DNS information recorded in WiFi _ resolve.conf from a DNS file WiFi _ resolve.conf corresponding to a WiFi local area network that APP1 can currently use, further parses an IP (Internet Protocol) address of a corresponding DNS server from the DNS information, and then transmits data to the parsed IP address according to the route rt _ WiFi. Therefore, the route corresponding to the selected network (path) can be ensured to be matched with the DNS server, and the domain name in the data transmitted through the route can be resolved by the corresponding (correct) DNS server, so that the reliability of data transmission can be improved.

S406: and feeding back the information which is available without the network at present to the application sending the data transmission request.

Preferably, after determining in step S403 that the determination result is negative (that is, each network that the application has the right to use does not belong to the currently assignable network), the middle layer program determines that the application is currently available without a network, generates information that the application is currently available without a network, and feeds back the information to the application that sends the data transmission request. Further, the middle tier program stops responding to the received data transfer request of the application (e.g., ignores the data transfer request).

The transmission module 503 is configured to transmit data of the application according to a network currently available for the application.

Preferably, the currently available network determining module 502 is specifically configured to determine a currently assignable network according to an opened network and a preset network mutual exclusion policy; according to the priorities of various networks in the routing strategy of the application, whether each network which the application has the right to use belongs to the currently allocable network is judged step by step; and if the judgment result is yes, taking the network which is judged to be the related network as the network which can be currently used by the application.

Preferably, the routing policy determining module 501 is further configured to determine the applied routing policy in advance by: when a network authority application request of an application is received, determining at least one network applied by the application; and determining at least one network which the application is authorized to use according to the at least one network applied by the application, the multiple networks supported by the intelligent equipment and a preset network mutual exclusion strategy.
