Method and device for resolving dual subscriber identity module paging conflict

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.

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.
