Referring to fig. 1B, fig. 1B is a schematic flowchart of a path switching method provided in an embodiment of the present application, where the path switching method described in this embodiment is applied to the electronic device shown in fig. 1A, and the electronic device includes a cellular communication module, a low power wide area network LPWAN communication module, a first radio frequency front end module, a second radio frequency front end module, a first antenna, and a second antenna; the cellular communication module is respectively connected with the first radio frequency front end module and the second radio frequency front end module to form a first cellular radio frequency channel and a second cellular radio frequency channel; the LPWAN communication module is connected with the second radio frequency front end module to form an LPWAN radio frequency channel; the first cellular radio frequency path is connected with the first antenna, and the path switching method comprises the following steps:
101. and acquiring the opening state of the LPWAN communication module.
The on state of the LPWAN communication module may include any one of the following: the LPWAN communication module is in an on state, the LPWAN communication module is in an off state, a receiving function of the LPWAN communication module is in an on or off state, a transmitting function of the LPWAN communication module is in an on or off state, and the like. In this embodiment, the on state of the LPWAN communication module may be obtained by the processor.
102. And determining a path to be connected of the second antenna according to the starting state, wherein the path to be connected is one of the second cellular radio frequency path and the LPWAN radio frequency path.
In the embodiment of the present application, as can be seen from fig. 1A, the LPWAN radio frequency path and the second cellular radio frequency path share one antenna, and therefore, it can be determined whether to connect the second antenna to the second cellular radio frequency path or the LPWAN radio frequency path according to the on state of the LPWAN communication module, so that a separate antenna does not need to be added to the LPWAN radio frequency path. Specifically, the LPWAN communication modules may be set to have different open states, and may be provided with a band connection path to which the second antenna is connected.
Optionally, in the step 102, determining a path to be connected to the second antenna according to the on state may include the following steps:
21. when the LPWAN communication module closes a first preset function, the second cellular radio frequency channel is used as the channel to be connected;
22. and when the LPWAN communication module starts a second preset function, taking the LPWAN radio frequency path as the path to be connected.
The first preset function may be, for example, a receiving function and/or a transmitting function of the LPWAN communication module, and the second preset function may be, for example, a receiving function and/or a transmitting function of the LPWAN communication module. In a specific implementation, the second cellular radio frequency path may be used as a path to be connected when the LPWAN communication module closes the first preset function, for example, when the receiving function or the transmitting function of the LPWAN communication module is closed, the second cellular radio frequency path may be used as a path to be connected; the LPWAN radio frequency path may be used as the path to be connected when the LPWAN communication module turns on the second preset function, for example, when the receiving function or the transmitting function of the LPWAN communication module turns on, the LPWAN radio frequency path may be used as the path to be connected. Therefore, one of the second cellular radio frequency path and the LPWAN radio frequency path can be determined as a path to be connected according to the opening state of the receiving or transmitting function of the LPWAN communication module, and therefore the communication quality of the cellular communication system can be guaranteed preferentially.
Optionally, in step 102, determining a path to be connected to the second antenna according to the on state may include the following steps:
23. when the LPWAN communication module is started, acquiring a first signal strength corresponding to the first cellular radio frequency channel;
24. if the first signal strength is greater than a first threshold value or smaller than a second threshold value, taking the LPWAN radio frequency path as the path to be connected, wherein the first threshold value is greater than the second threshold value;
25. and if the first signal strength is greater than the second threshold and less than or equal to the first threshold, taking the second cellular radio frequency channel as the channel to be connected.
The first threshold and the second threshold may be set by a user or by default. In specific implementation, when the LPWAN communication module is turned on, a first signal strength corresponding to the first cellular radio frequency path may be obtained, and if the first signal strength is greater than a first threshold value, or is less than a second threshold value, the LPWAN radio frequency path may be used as a path to be connected, where when the first signal strength is greater than the first threshold value, the first cellular radio frequency path may operate at the first signal strength to ensure communication quality of the first cellular radio frequency path, so that the first cellular radio frequency path and the LPWAN radio frequency path operate simultaneously, and communication quality of the first cellular radio frequency path and the LPWAN radio frequency path may be ensured. When the first signal strength is smaller than the second threshold value, if the second antenna and the second cellular radio frequency channel are used, the communication quality of the second cellular radio frequency channel is difficult to guarantee, so that the LPWAN radio frequency channel can be used as a channel to be connected and is connected with the second antenna through the LPWAN radio frequency channel.
If the first signal strength is greater than the second threshold value, the second cellular radio frequency channel can be used as a channel to be connected, and therefore communication connection of the second cellular radio frequency channel can be guaranteed preferentially.
103. And connecting the second antenna with the path to be connected.
In the embodiment of the present application, the second antenna is connected to the to-be-connected path, specifically, the second antenna may be connected to the to-be-connected path through the second radio frequency front end module, and when the to-be-connected path is the second cellular radio frequency path, the second antenna may be connected to the second cellular radio frequency path; when the path to be connected is the LPWAN radio path, the second antenna may be connected with the LPWAN radio path. Therefore, the LPWAN radio frequency channel and the second cellular radio frequency channel can share one antenna, the connection between the LPWAN radio frequency channel and the cellular radio frequency diversity and the second antenna is flexibly controlled according to the opening state of the LPWAN communication module, and the communication function of cellular communication is guaranteed preferentially.
Optionally, when the first signal strength is greater than the second threshold and is less than or equal to the first threshold, and the second cellular radio frequency path is the path to be connected, the step 103 of connecting the second antenna with the path to be connected may include the following steps:
31. establishing a connection between the second antenna and the second cellular radio frequency path at preset time intervals;
32. and when the connection duration reaches the target duration, disconnecting the second antenna from the second cellular radio frequency channel, wherein the target duration is less than the preset time interval.
The preset time interval may be set by a user or by default. The target duration may be preset by a user or a system.
Optionally, the determination may also be performed according to a first signal strength corresponding to the first cellular radio frequency access and a current service state of the cellular communication module, where the greater the first signal strength is, the longer the target duration is.
In the embodiment of the application, when the first signal strength is greater than the second threshold and less than or equal to the first threshold and the second cellular radio frequency path serves as a path to be connected, the connection between the second antenna and the second cellular radio frequency path may be established at preset time intervals, and then, when the connection duration reaches the target duration, the connection between the second antenna and the second cellular radio frequency path may be disconnected.
Optionally, in this embodiment of the present application, the following steps may also be included:
a1, obtaining the current service state of the cellular communication module;
a2, determining a reference time length corresponding to the current service state according to a preset corresponding relation between the service state and the time length;
a3, determining a target duration adjustment value corresponding to the first signal strength according to a corresponding relation between preset signal strength and a duration adjustment value;
and A4, determining the target time length according to the reference time length and the target time length adjusting value.
Wherein the current traffic state of the cellular communication module may comprise any one of: the mobile terminal comprises a standby state, a search/paging state, a call state and a data connection service state, wherein the search state refers to whether a call is received or not, and the data connection service state refers to a state with data transmission. In different service states, the requirement for the connection duration of the cellular communication module is different, for example, in the data connection service state, the target duration of the connection may be longer, and in the standby state, the target duration may be shorter.
In the implementation of the present application, a corresponding relationship between a preset service state and a duration and a corresponding relationship between a preset signal strength and a duration adjustment value may be preset, then, a reference duration corresponding to a current service state is determined according to the corresponding relationship between the preset service state and the duration, a target duration adjustment value corresponding to a first signal strength is determined according to the corresponding relationship between the preset signal strength and the duration adjustment value, for example, assuming that the current service state is a call state, a reference duration t1 corresponding to the call state and a target duration adjustment value Δ t corresponding to the first signal strength may be determined, and then, the target duration is determined according to the reference durations t1 and Δ t.
It can be seen that the path switching method described in this embodiment of the present application is applied to an electronic device, obtains an open state of an LPWAN communication module, determines a path to be connected of a second antenna according to the open state, where the path to be connected is one of a second cellular radio frequency path and an LPWAN radio frequency path, and connects the second antenna with the path to be connected.
