The temperature sensor 180J is used to detect temperature. In some embodiments, electronic device 100 implements a temperature processing strategy using the temperature detected by temperature sensor 180J. For example, when the temperature reported by the temperature sensor 180J exceeds a threshold, the electronic device 100 performs a reduction in performance of a processor located near the temperature sensor 180J, so as to reduce power consumption and implement thermal protection. In other embodiments, the electronic device 100 heats the battery 142 when the temperature is below another threshold to avoid the low temperature causing the electronic device 100 to shut down abnormally. In other embodiments, when the temperature is lower than a further threshold, the electronic device 100 performs boosting on the output voltage of the battery 142 to avoid abnormal shutdown due to low temperature.

The touch sensor 180K is also referred to as a "touch panel". The touch sensor 180K may be disposed on the display screen 194, and the touch sensor 180K and the display screen 194 form a touch screen, which is also called a "touch screen". The touch sensor 180K is used to detect a touch operation applied thereto or nearby. The touch sensor can communicate the detected touch operation to the application processor to determine the touch event type. Visual output associated with the touch operation may be provided through the display screen 194.

In one possible example, the priority corresponding to the second request instruction is the first priority, the second request instruction is an instruction sent by the physical layer corresponding to the first SIM card to the radio frequency control layer, and the second request instruction is used to maintain the data connection of the first SIM card.

The first SIM card is a data card and is in an RRC (radio resource control) connected state, in the RRC connected state, a physical layer corresponding to the first SIM card continuously sends a second request instruction to a radio frequency control layer with a first priority, and the first priority is determined by the physical layer corresponding to the first SIM card.

As can be seen, in this example, the first priority corresponding to the second request instruction is flexible, and the physical layer may change according to the current scenario, so as to provide a reasonable basis for the subsequent radio resource control layer to allocate radio resources, which is beneficial to improving accuracy, flexibility, and rationality of radio resource allocation.

Wherein, the first target radio frequency resource is arbitrated by the radio frequency control layer or is allocated to the second SIM card according to the priority after arbitrating the priority by the physical layer, as shown in fig. 3B, the specific implementation manner of allocating the first target radio frequency resource to the second SIM card according to the preset policy may be various, for example, the radio frequency resource control layer may allocate the first target radio frequency resource according to the priority of the first request instruction and the second request instruction, or the radio frequency resource control layer may allocate the radio frequency resource to the first SIM card and the second SIM card according to the average allocation time distribution unit, or the radio frequency resource control layer may allocate the radio frequency resource to the first SIM card and the second SIM card according to the certain proportion allocation time distribution unit, and the time of using the radio frequency resource by the second SIM card does not exceed the preset time period, so as to ensure that the RRC connection state of the first SIM card is not released, and are not limited herein.

In one possible example, the method further comprises:

sending the first radio frequency resource request of the second SIM card to the first SIM card;

and switching the first priority to be a second priority through a physical layer corresponding to the first SIM card, so as to send the second request instruction to the radio frequency control layer through the second priority, wherein the second priority is higher or lower than the first priority, and the second priority is determined by the physical layer corresponding to the first SIM card according to the first radio frequency resource request.

The first SIM card informs the physical layer when receiving the first radio frequency resource request, and the physical layer determines a first priority corresponding to the first radio frequency resource request according to a target service corresponding to the first radio frequency resource request, and further the physical layer corresponding to the first SIM card switches the priority according to a time at which the RRC connection may be out of synchronization, for example, according to an evaluation time of the radio link monitor, and if a time difference between a current time and the evaluation time of the radio link monitor is greater than a preset threshold, the first priority is switched to a second priority, and the second priority is lower than the first priority; and when the time difference between the current time and the evaluation time of the wireless link monitor is smaller than a preset threshold value, switching the first priority to be a second priority, wherein the second priority is higher than the first priority.

When the second SIM cards are multiple second SIM cards, the physical layer corresponding to the first SIM card may switch the priority according to the time at which the RRC connection may be out of synchronization in the process of using the radio frequency resources by the multiple second SIM cards, for example, if a time difference between the current time and the evaluation time of the radio link monitor is greater than a preset threshold, the physical layer switches to the low priority, so that the radio frequency control layer allocates the radio frequency resources to the second SIM card 1, then switches to the high priority before the evaluation time of the radio link monitor, and then switches to the low priority again after the evaluation of the radio link monitor, so that the radio frequency control layer allocates the radio frequency resources to the second SIM card 2.

As can be seen, in this example, the physical layer corresponding to the first SIM card may be switched to the second priority according to the first radio frequency resource request corresponding to the second SIM card and the current connection condition of the first SIM card RRC, which affects the result of allocating radio frequency resources by the radio frequency control layer, instead of fixing the priority according to the target service, and is beneficial to improving the flexibility of radio frequency resource allocation.

In one possible example, the second priority is lower than the first priority, and after the switching the first priority to the second priority by the physical layer corresponding to the first SIM card, the method further includes:

before the RRC connection of the first SIM card is determined to be out of synchronization, switching the second priority to a third priority through a physical layer corresponding to the first SIM card, so as to send the second request instruction to the radio frequency control layer through the third priority, where the third priority is higher than the first priority.

Here, when there is only one second SIM card, the procedure of this example is shown in fig. 3C, and before the RRC connection of the first SIM card is determined to be out of synchronization, for example, it may be before the timer T311 expires.

As can be seen, in this example, before the RRC connection of the first SIM card is determined to be out of synchronization, the physical layer raises the second priority to the third priority, so that the radio frequency control layer allocates the radio frequency resource to the first SIM card, which effectively ensures the data connection of the first SIM card.

In one possible example, the first SIM card is in a Connected Discontinuous Reception (CDRX) scenario, and the method further includes:

when the first SIM card is in a continuous receiving state, switching the first priority to be a second priority through a physical layer corresponding to the first SIM card, wherein the second priority is higher than the first priority;

when the first SIM card is in a discontinuous reception dormant state, switching the first priority to a second priority through a physical layer corresponding to the first SIM card, wherein the second priority is lower than the first priority.

When only one second SIM card is present, as shown in fig. 3D, the physical layer monitors the state of the first SIM card, and when it is monitored that the first SIM card is in a continuous Reception state on duration, in order to ensure that the RRC connection of the first SIM card is not released, the priority is raised, and when it is monitored that the first SIM card is in a Discontinuous Reception sleep state (DRX sleep), the priority is lowered, so that at least one second SIM card can use the radio frequency resource in this time period, and when the at least one second SIM card includes a plurality of second SIM cards, and when the first SIM card is in the Discontinuous Reception sleep state, the radio frequency control layer can equally allocate the time period or allocate the time period to the plurality of second SIM cards according to a ratio to use the radio frequency resource.

As can be seen, in this example, when the first SIM card is in CDRX, the physical layer flexibly switches the priority of the second request instruction according to the state of the first SIM card, which not only ensures the data connection of the first SIM card, but also ensures the use of the radio frequency resource of the second SIM card, and is beneficial to improving the rationality and flexibility of the radio frequency resource allocation.

In one possible example, the allocating, according to a preset policy, a first target radio frequency resource to the second SIM card includes:

when the priorities corresponding to the first request instruction and the second request instruction are the same, determining a first time period through the radio frequency control layer, wherein the first time period and the second time period are allocated by the radio frequency control layer according to a first proportion, and the second time period is a time period for the radio frequency control layer to allocate radio frequency resources to the first SIM card;

allocating, by the radio frequency control layer, the first target radio frequency resource for the first time period to the second SIM card.

When there is only one second SIM card, for example, as shown in fig. 3E, when the second SIM card is a plurality of SIM cards, the radio frequency control layer may allocate radio frequency resources to the plurality of second SIM cards according to a second ratio in a first time period.

The first ratio and the second ratio may be various, for example, 1:1, 1:2, and the like, and are not limited herein.

As can be seen, in this example, when the priorities corresponding to the first request instruction and the second request instruction are the same, the radio frequency control layer may allocate radio frequency resources to the first SIM card and the second SIM card according to a certain proportion, instead of allocating the radio frequency resources through the protocol stack under the condition that the priorities are not clear, which is beneficial to improving the rationality of radio frequency resource allocation.

In one possible example, the at least one second SIM card is a plurality of second SIM cards, and the allocating the first target radio frequency resource to the second SIM card according to the preset policy includes:

when the priority of a plurality of first request instructions corresponding to a plurality of second SIM cards is higher than the priority corresponding to a second request instruction, determining a time division unit for allocating radio frequency resources to each second SIM card through the radio frequency control layer, wherein the sum of the time division units occupied by the plurality of second SIM cards is less than a preset time period, and the preset time period is less than the time interval between two evaluations of a physical layer wireless link monitor corresponding to the first SIM card;

and distributing the first target radio frequency resource to the plurality of second SIM cards according to the time unit through the radio frequency control layer.

When the priority of the first request instructions is higher than the priority corresponding to the second request instructions, the radio frequency control layer firstly allocates radio frequency resources corresponding to the time division units to the second SIM cards.

When the preset time period is less than the time interval (e.g. 100-.

As can be seen, in this example, when the radio frequency control layer allocates the radio frequency resource to the plurality of second SIM cards, the sum of the time division units occupied by the plurality of second SIM cards is smaller than a preset time period, and the preset time period is smaller than a time interval between two evaluations of the physical layer wireless link monitor corresponding to the first SIM card, so that the first SIM card can be effectively prevented from being judged to be out of synchronization.

S404, the electronic device sends a first request instruction to a radio frequency control layer through a physical layer corresponding to the second SIM card according to the first priority, wherein the first priority is determined by the physical layer corresponding to the second SIM card according to the first radio frequency resource request.

In addition, the physical layer corresponding to the first SIM card can be switched to the second priority according to the first radio frequency resource request corresponding to the second SIM card and the current connection situation of the first SIM card RRC, which affects the result of the radio frequency resource allocation by the radio frequency control layer, instead of fixing the priority according to the target service, and is beneficial to improving the flexibility of the radio frequency resource allocation.
