Method and device for resolving dual subscriber identity module paging conflict

1. A method for resolving a dual Subscriber Identity Module (DS) paging conflict, applied to user equipment (UE), the method comprising:

acquiring a Connected Discontinuous Reception (cDRX) long cycle for paging a data service Subscriber Identity Module (SIM) in a Long Term Evolution (LTE) connected state and a Discontinuous Reception (DRX) cycle for paging a call service SIM in an idle state;

determining that the cDRX long cycle equals the DRX cycle by determining that a parameter longDRX of cDRX of the data service SIM and a parameter defaultPagingcycle of DRX of the call service SIM are configured to be equal;

in response to determining that the cDRX long cycle equals the DRX cycle, sending a DRX cycle changing request to a base station associated with the call service SIM; and

increasing the DRX cycle based on a DRX cycle changing response sent by the base station, wherein a new DRX cycle after the increasing is greater than the cDRX long cycle,

wherein sending the DRX cycle changing request to the base station associated with the call service SIM comprises:

sending a message to a Network Access Service (NAS) module, to instruct the NAS module to send the DRX cycle changing request to the base station; and

sending, using the NAS module, the DRX cycle changing request to the base station, wherein the DRX cycle changing request is included in one of a tracking area update request or an attach request, wherein the DRX cycle is changed by implementing a re-registration flow.

2. The method of claim 1 , wherein sending the DRX cycle changing request to the base station associated with the call service SIM comprises one of:

determining a target DRX cycle, including the target DRX cycle in the DRX cycle changing request, and sending the DRX cycle changing request to the base station; or

including request information in the DRX cycle changing request, the request information being configured to request the base station to assign the new DRX cycle.

3. The method of claim 2 , before increasing the DRX cycle based on the DRX cycle changing response sent by the base station, further comprising:

receiving the DRX cycle changing response sent by the base station, the DRX cycle changing response comprising the new DRX cycle, the new DRX cycle equaling the target DRX cycle or differing from the target DRX cycle.

4. A method for resolving a dual Subscriber Identity Module (DS) paging conflict, applied to a base station, the method comprising:

receiving a Discontinuous Reception (DRX) cycle changing request sent by user equipment (UE) for changing a DRX cycle for paging a call service Subscriber Identity Module (SIM) in an idle state and associated with the base station; and

generating a DRX cycle changing response based on the DRX cycle changing request, and sending the DRX cycle changing response to the UE, the DRX cycle changing response comprising a new DRX cycle greater than a Connected Discontinuous Reception (cDRX) long cycle for paging a data service SIM in a Long Term Evolution (LTE) connected state,

wherein receiving the DRX cycle changing request sent by the UE for changing the DRX cycle comprises:

receiving the DRX cycle changing request sent by a Network Access Service (NAS) module, wherein the DRX cycle changing request is included in one of a tracking area update request or an attach request, wherein the DRX cycle is changed by implementing a re-registration flow.

5. The method of claim 4 , wherein generating the DRX cycle changing response based on the DRX cycle changing request, and sending the DRX cycle changing response to the UE comprises one of:

in response to determining that the DRX cycle changing request includes a target DRX cycle, and that the target DRX cycle is not supported, configuring the new DRX cycle, including the new DRX cycle in the DRX cycle changing response, and sending the DRX cycle changing response to the UE; or

in response to determining that the DRX cycle changing request includes no target DRX cycle, configuring the new DRX cycle, including the new DRX cycle in the DRX cycle changing response, and sending the DRX cycle changing response to the UE.

6. User equipment (UE), comprising:

a processor; and

a memory storing an instruction executable by the processor,

wherein the processor is configured to:

acquire a Connected Discontinuous Reception (cDRX) long cycle for paging a data service Subscriber Identity Module (SIM) in a Long Term Evolution (LTE) connected state and a Discontinuous Reception (DRX) cycle for paging a call service SIM in an idle state;

determine that the cDRX long cycle equals the DRX cycle by determining that a parameter longDRX of cDRX of the data service SIM and a parameter defaultPagingcycle of DRX of the call service SIM are configured to be equal;

in response to determining that the cDRX long cycle equals the DRX cycle, send a DRX cycle changing request to a base station associated with the call service SIM; and

increase the DRX cycle based on a DRX cycle changing response sent by the base station, wherein a new DRX cycle after the increasing is greater than the cDRX long cycle,

wherein in sending the DRX cycle changing request to the base station associated with the call service SIM, the processor is further configured to:

send a message to a Network Access Service (NAS) module, to instruct the NAS module to send the DRX cycle changing request to the base station; and

send, using the NAS module, the DRX cycle changing request to the base station, wherein the DRX cycle changing request is included in one of a tracking area update request or an attach request, wherein the DRX cycle is changed by implementing a re-registration flow.

7. The UE of claim 6 , wherein in sending the DRX cycle changing request to the base station associated with the call service SIM, the processor is further configured to perform one of:

determining a target DRX cycle, including the target DRX cycle in the DRX cycle changing request, and sending the DRX cycle changing request to the base station; or

including request information in the DRX cycle changing request, the request information being configured to request the base station to assign the new DRX cycle.

8. The UE of claim 7 , wherein before increasing the DRX cycle based on the DRX cycle changing response sent by the base station, the processor is further configured to:

receive the DRX cycle changing response sent by the base station, the DRX cycle changing response comprising the new DRX cycle, the new DRX cycle equaling the target DRX cycle or differing from the target DRX cycle.
