USER EQUIPMENT AND METHOD FOR MULTI-SIM OPERATION
A user equipment and a method for a multi-Subscriber Identity Module (multi-SIM) operation are provided. The method includes registering to a first network associated with a first Subscriber Identity Module (SIM) and a second network associated with a second SIM; determining whether a paging collision associated with the first network and the second network is detected; and initiating a paging collision resolution procedure associated with a selected network to resolve the paging collision after the paging collision is detected, where the selected network is the first network or the second network.
1 . A method for a multi-subscriber identity module (multi-SIM) operation performed by a user equipment (UE), the method comprising:
registering to a first network associated with a first Subscriber Identity Module (SIM) and a second network associated with a second SIM;
determining whether a paging collision associated with the first network and the second network is detected; and
initiating a paging collision resolution procedure associated with a selected network to resolve the paging collision after the paging collision is detected, the selected network being the first network or the second network.
2 . The method according to claim 1 , wherein a non-access stratum (NAS) layer of the UE transmits a status of the multi-SIM operation to a radio resource control (RRC) layer of the UE to inform the RRC layer of the UE that the multi-SIM operation is activated.
3 . The method according to claim 1 , wherein a non-access stratum (NAS) layer of the UE transmits architecture information to a radio resource control (RRC) RRC layer of the UE, the architecture information comprising a number of receivers in the UE.
4 . The method according to claim 1 , wherein initiating the paging collision resolution procedure associated with the selected network comprises
transmitting, to the selected network, assistance information including a suggested paging parameter.
5 . The method according to claim 4 , further comprising:
receiving a command from the selected network after transmitting the assistance information.
6 . The method according to claim 5 , wherein the command includes new paging information associated with the selected network to calculate new paging occasions for the selected network.
7 . The method according to claim 6 , wherein the new paging information is an offset to a UE identity (ID) of the UE.
8 . The method according to claim 1 , wherein the selected network is determined based on priorities of the first network and the second network.
9 . The method according to claim 1 , wherein initiating the paging collision resolution procedure associated with the selected network comprises omitting monitoring a collided paging occasion (PO) or a collided paging frame (PF) of the selected network.
10 . The method according to claim 1 , further comprising:
initiating the paging collision resolution procedure associated with the selected network to resolve the paging collision after determining that the selected network supports the paging collision resolution procedure.
11 . A user equipment (UE) for a multi-subscriber identity module (multi-SIM) operation, the UE comprising:
one or more non-transitory computer-readable media storing computer-executable instructions; and
at least one processor coupled to the one or more non-transitory computer-readable media, the at least one processor being configured to execute the computer-executable instructions to cause the UE to:
register to a first network associated with a first Subscriber Identity Module (SIM) and a second network associated with a second SIM;
determine whether a paging collision associated with the first network and the second network is detected; and
initiate a paging collision resolution procedure associated with a selected network to resolve the paging collision after the paging collision is detected, the selected network being the first network or the second network.
12 . The UE according to claim 11 , wherein a non-access stratum (NAS) layer of the UE transmits a status of the multi-SIM operation to a radio resource control (RRC) layer of the UE to inform the RRC layer of the UE that the multi-SIM operation is activated.
13 . The UE according to claim 11 , wherein a non-access stratum (NAS) layer of the UE transmits architecture information to a radio resource control (RRC) layer of the UE, the architecture information comprising a number of receivers in the UE.
14 . The UE according to claim 11 , wherein initiating the paging collision resolution procedure associated with the selected network comprises
transmitting, to the selected network, assistance information including a suggested paging parameter.
15 . The UE according to claim 14 , wherein the at least one processor is further configured to execute the computer-executable instructions to cause the UE to:
receive a command from the selected network after transmitting the assistance information.
16 . The UE according to claim 15 , wherein the command includes new paging information associated with the selected network to calculate new paging occasions for the selected network.
17 . The UE according to claim 16 , wherein the new paging information is an offset to a UE identity (ID) of the UE.
18 . The UE according to claim 11 , wherein the selected network is determined based on priorities of the first network and the second network.
19 . The UE according to claim 11 , wherein initiating the paging collision resolution procedure associated with the selected network comprises
omitting monitoring a collided paging occasion (PO) or a collided paging frame (PF) of the selected network.
20 . The UE according to claim 11 , wherein the at least one processor is further configured to execute the computer-executable instructions to cause the UE to:
initiate the paging collision resolution procedure associated with the selected network to resolve the paging collision after determining that the selected network supports the paging collision resolution procedure.
