Abstract
A wireless communication method and Multi-SIM user equipment are provided. The wireless communication method for Multi-SIM dual standby (DSDS) technology is applied on Multi-SIM user equipment (UE) which is capable of carrier aggregation (CA) or dual connectivity (DuCo). The wireless communication method includes the steps of determining whether a packet switch (PS) or circuit switch (CS) paging is received on a second SIM card when a first PS call is ongoing in a first SIM card; and suspending the first PS call which is ongoing on the first SIM card if the packet switch (PS) or circuit switch (CS) paging is received on the second SIM card.

A wireless communication method for dual SIM dual standby (DSDS) technology, which is applied on Multi-SIM user equipment (UE) which is capable of carrier aggregation (CA) or dual connectivity (DuCo), the wireless communication method comprising:
- determining whether a packet switch (PS) or circuit switch (CS) paging is received on a second SIM card when a first PS call is ongoing in a first SIM card;
- suspending the first PS call which is ongoing on the first SIM card if the packet switch (PS) or circuit switch (CS) paging is received on the second SIM card;
- and
- initiating a protection timer when the first PS call is suspended;
- and
- resuming the first PS call when the protection timer expires.
A Multi-SIM user equipment (UE) which is capable of carrier aggregation (CA) or dual connectivity (DuCo), for dual SIM dual standby (DSDS) technology, the Multi-SIM user equipment comprising:
- a processor, configured to determine whether a packet switch (PS) or circuit switch (CS) paging is received on a second SIM card when a first PS call is ongoing in a first SIM card, and suspend the first PS call which is ongoing on the first SIM card if the packet switch (PS) or circuit switch (CS) paging is received on the second SIM card, wherein the processor further initiates a protection timer when the first PS call is suspended and resumes the first PS call when the protection timer expires.
