most of the communication frequency range of the low-power-consumption wide area network LPWAN communication module is below 1GHz, and the range of the cellular communication frequency range is far larger than that of the low-power-consumption wide area network, so that when the low-power-consumption wide area network LPWAN communication module and a radio frequency diversity path of cellular communication share one antenna, communication branches are switched and coordinated, and the working state of the antenna is switched.
In specific implementation, when the cellular communication module needs diversity, the electronic device switches the communication branch of the DRX module to a radio frequency branch corresponding to cellular communication through the AP or the low power consumption wide area network, and the electronic device adjusts the working state of the diversity antenna DRX ANT to a state required by the cellular communication frequency band through the AP or the LPWAN communication module.
S203, the electronic equipment controls the LPWAN communication module to stop sending and receiving signals.
When the electronic equipment is in Cellular communication diversity, the AP or LPWAN communication module controls the low-power-consumption wide area network LPWAN communication module to stop sending and receiving signals.
It can be seen that, in the embodiment of the present application, when the electronic device first detects that both the Cellular communication module and the LPWAN communication module are started, then detects whether the Cellular communication module needs diversity; if yes, switching a communication branch of the DRX module to a Cellular radio frequency branch through the communication branch switching execution module, and switching the working state of the diversity antenna to a state required by a Cellular communication frequency band, wherein the Cellular radio frequency branch is connected with the diversity antenna, and the communication branch switching execution module comprises an AP (access point) or a low power consumption wide area network (LPWAN) communication module; and finally, controlling the LPWAN communication module to stop sending and receiving signals. It can be seen that, in the embodiment of the present application, the electronic device can control the communication branch of the DRX module to switch to the cellular communication branch connected to the diversity antenna and control the working state of the diversity antenna to switch to the state corresponding to the cellular frequency band when detecting that the cellular communication module and the LPWAN communication module are both started and the cellular communication module needs diversity, thereby implementing communication control when multiple communication modes share the diversity antenna, reducing the cost of the device, and improving the flexibility of controlling the common diversity antenna.
In one possible example, when the communication branch switching performing module includes the LPWAN communication module, the switching, by the communication branch switching performing module, the communication branch of the DRX module to a Cellular radio frequency branch to switch an operating state of the diversity antenna to a state required by a Cellular communication band, where the Cellular radio frequency branch is connected to the diversity antenna, includes: sending first notification information to the LPWAN communication module through the Cellular communication module, wherein the first notification information comprises the current working frequency range of the Cellular communication module; and switching the communication branch of the DRX module to a Cellular radio frequency branch connected with the diversity antenna through the LPWAN communication module according to the first notification message, and switching the working state of the diversity antenna to a state required by a Cellular communication frequency band.
Wherein the first notification message at least includes an operating frequency band of the current Cellular communication module or control logic of a DRX module and an antenna, which is sent by the Cellular communication module to the LPWAN communication module.
In specific implementation, when the electronic device detects that the Cellular communication module needs diversity, the working frequency band of the Cellular communication module or the control logic of the DRX module and the antenna, etc. are sent to the LPWAN communication module, the LPWAN communication module controls the DRX module to switch to a Cellular radio frequency branch connected to the diversity antenna, and the electronic device controls the working state of the diversity antenna to switch to a state required by the communication frequency band of the current Cellular communication module through the LPWAN communication module.
In this example, the electronic device can control branch switching of the cellular diversity and working state switching of the diversity antenna through the LPWAN communication module, so that flexibility and convenience of switching among multiple communication modes are achieved.
In one possible example, after the controlling the LPWAN communication module to stop transmitting and receiving signals, further comprising: when the Cellular communication module is detected to stop using the diversity antenna, sending a second notification message to the LPWAN communication module through the Cellular communication module, wherein the second notification message comprises information that the diversity antenna is released; and controlling the DRX module to be switched to an LPWAN radio frequency branch connected with the diversity antenna through the LPWAN communication module according to the second notification message, and controlling the state required for switching the diversity antenna to a low-power-consumption wide area network communication band through the LPWAN communication module.
The second notification message is information that the hierarchical antenna is released and is sent by the Cellular communication module to the LPWAN communication module, when the electronic device detects that diversity of the Cellular communication module is ended, the electronic device sends information that diversity is ended and the diversity antenna is released to the LPWAN communication module through the Cellular communication module, and after receiving the notification message, the LPWAN communication module switches a communication branch of the DRX module to a low-power-consumption wide area network radio frequency branch connected to the diversity antenna, and switches the working state of the diversity antenna to a state required by a communication frequency band of the current LPWAN communication module.
Therefore, in this example, after the Cellular communication module cluster is ended, the electronic device can switch the states of the communication branch and the antenna through the LPWAN communication module, so that flexibility and convenience of multi-mode communication switching are realized.
In a possible example, when the communication branch switching performing module includes the AP, the communication branch of the DRX module is switched to a Cellular radio frequency branch by the communication branch switching performing module, and a working state of the diversity antenna is switched to a state required by a Cellular communication frequency band, where the Cellular radio frequency branch is connected to the diversity antenna, including: controlling the Cellular communication module to send a third notification message to the AP; and controlling the DRX module to be switched to the Cellular radio frequency branch connected with the diversity antenna through the AP according to the third notification message, and switching the diversity antenna to a state required by the Cellular communication frequency band.
The third notification message is information about an operating frequency band of the current Cellular communication module or a DRX module and control logic of an antenna, which is sent by the Cellular communication module to the AP, and the diversity process control behavior of the Cellular communication module may also be implemented by the AP.
In a specific implementation, when the electronic device detects that the Cellular communication module needs to use a diversity antenna, the Cellular communication module sends information such as a current working frequency band of the Cellular communication module or control logic of the DRX module and the antenna to the AP, and after receiving the information, the AP controls the DRX module to switch to a Cellular radio frequency branch connected to the diversity antenna and controls a working state of the diversity antenna to switch to a state required by the communication frequency band of the Cellular communication module through the AP.
As can be seen, in this example, the electronic device can control the DRX module to switch the working states of the communication branch and the diversity antenna based on the AP, thereby achieving flexibility of switching the diversity communication branch and diversity of control modes.
In one possible example, the controlling the LPWAN communication module to stop transmitting and receiving signals includes: and sending fourth notification information to the LPWAN communication module through the AP, and controlling the LPWAN communication module to receive the fourth notification information and stop sending and receiving signals.
The fourth notification message is information that the diversity antenna sent by the AP to the LPWAN communication module is occupied by a Cellular communication module or the diversity antenna is unavailable to the LPWAN communication module.
In a specific implementation, when the Cellular communication module uses a diversity antenna, the electronic device sends information that the diversity antenna is occupied to the LPWAN communication module through the AP, and the LPWAN communication module stops sending and receiving signals after receiving the information.
As can be seen, in this example, the electronic device can send information to the LPWAN communication module through the AP and stop sending and receiving signals by the low-power wide area network, so that flexibility in controlling switching of diversity branches and diversity of control modes are achieved.
In one possible example, after the controlling the LPWAN communication module to stop transmitting and receiving signals, further comprising: when the Cellular communication module is detected to stop using the diversity antenna, informing the AP through the Cellular communication module; and controlling the communication branch of the DRX module to be switched to an LPWAN radio frequency branch connected with the diversity antenna through the AP, and switching the working state of the diversity antenna to a state required by an LPWAN communication frequency band.
When the electronic device detects that the Cellular communication module stops using the diversity antenna, the electronic device notifies the AP through the Cellular communication module, wherein the notification message at least comprises information that the diversity antenna is released by the Cellular communication module or information that the diversity antenna is available to the LPWAN communication module; and after receiving the notification, the AP controls the DRX module to switch to a low-power-consumption wide area network radio frequency branch connected with the diversity antenna and controls the working state of the diversity antenna to switch to a state required by the communication frequency band of the LPWAN communication module at the moment.
In this example, the electronic device can switch the DRX module to the low-power-consumption wide area network radio frequency branch and switch the operating state of the antenna to the state required by the low-power-consumption wide area network communication frequency band by using the AP when the Cellular communication module finishes using the diversity antenna, thereby achieving flexibility in controlling switching of the diversity branch and diversity of control modes.
In a possible example, after detecting whether diversity is needed by the Cellular communication module when it is detected that both the Cellular communication module and the LPWAN communication module are activated, the method further includes: if not, the communication branch of the DRX module is kept to be a low power consumption wide area network (LPWAN) communication branch connected with the diversity antenna, and the diversity antenna is kept in a state required by a low power consumption wide area network (LPWAN) communication frequency band.
When detecting that the Cellular communication module does not need diversity, the electronic device keeps the original communication branch of the DRX module and the original working state of a diversity antenna. The original communication branch is a low-power-consumption wide area network radio frequency branch connected with the diversity antenna, and the original state is a state required by the low-power-consumption wide area network communication frequency band when the working state of the diversity antenna is the low-power-consumption wide area network radio frequency branch.
Therefore, in this example, the electronic device can control the communication branch of the DRX module based on the detection result of whether the Cellular communication module needs diversity, so as to implement flexibility in controlling diversity branch switching.
In one possible example, before detecting whether diversity is needed by the Cellular communication module when it is detected that both the Cellular communication module and the LPWAN communication module are activated, the method further includes: detecting whether the Cellular communication module and the LPWAN communication module are both started; if yes, detecting whether the Cellular communication module needs diversity; if not, when the LPWAN communication module is determined to be closed, the working states of the discontinuous reception DRX module and the antenna are controlled through the Cellular communication module.
