Abstract

Claims (45)

1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:

transmitting, to an access and mobility management function (AMF) entity, a service request message associated with a service request procedure;

identifying a transmission failure of the service request message; and

in case that the service request procedure is triggered for requesting the AMF entity to release a non-access stratum (NAS) signaling connection, aborting the service request procedure upon occurrence of the transmission failure,

wherein the UE supports a multi universal subscriber identification module (MUSIM), and

wherein the releasing of the NAS signaling connection is requested for a first USIM of the UE due to an activity on a second USIM of the UE.

2. The method of claim 1 , wherein the UE is in a 5GMM-CONNECTED mode or in a 5GMM-CONNECTED mode with a radio resource control (RRC) inactive indication and rejects a radio access network (RAN) paging of the AMF entity.

3. The method of claim 1 , wherein the UE is in a 5GMM-IDLE mode and rejects a paging request of the AMF entity.

4. The method of claim 1 , further comprising:

locally releasing the NAS signaling connection;

stopping a timer associated with the service request procedure; and

locally releasing resources allocated for the service request procedure.

5. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:

transmitting, to a mobility management entity (MME), a service request message associated with a service request procedure;

identifying a transmission failure of the service request message; and

in case that the service request procedure is triggered for requesting the MME to release a non-access stratum (NAS) signaling connection, aborting the service request procedure upon occurrence of the transmission failure,

wherein the UE supports a multi universal subscriber identification module (MUSIM), and

wherein the releasing of the NAS signaling connection is requested for a first USIM of the UE due to an activity on a second USIM of the UE.

6. The method of claim 5 , wherein the UE rejects a paging request of the MME.

7. A user equipment (UE) in a wireless communication system, the UE comprising:

a transceiver;

a memory storing one or more computer programs; and

one or more processors communicatively coupled to the transceiver and the memory,

wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the UE to:

transmit, to an access and mobility management function (AMF) entity, a service request message associated with a service request procedure,

identify a transmission failure of the service request message, and

in case that the service request procedure is triggered for requesting the AMF entity to release a non-access stratum (NAS) signaling connection, abort the service request procedure upon occurrence of the transmission failure

wherein the UE supports a multi universal subscriber identification module (MUSIM), and

wherein the releasing of the NAS signaling connection is requested for a first USIM of the UE due to an activity on a second USIM of the UE.

8. The UE of claim 7 , wherein the UE is in a 5GMM-CONNECTED mode or in a 5GMM-CONNECTED mode with a radio resource control (RRC) inactive indication and rejects a radio access network (RAN) paging of the AMF entity.

9. The UE of claim 7 , wherein the UE is in a 5GMM-CONNECTED mode with an RRC inactive indication or in a 5GMM-IDLE mode and rejects a paging request of the AMF entity.

10. The UE of claim 7 , the computer-executable instructions, when executed by the one or more processors individually or collectively, further cause the UE to:

locally release the NAS signaling connection,

stop a timer associated with the service request procedure, and

locally release resources allocated for the service request procedure.

11. A user equipment (UE) in a wireless communication system, the UE comprising:

a transceiver;

a memory storing one or more computer programs; and

one or more processors communicatively coupled to the transceiver and the memory,

wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the UE to:

transmit, to a mobility management entity (MME), a service request message associated with a service request procedure,

identify a transmission failure of the service request message, and in case that the service request procedure is triggered for requesting the MME to release a non-access stratum (NAS) signaling connection, abort the service request procedure upon occurrence of the transmission failure,

wherein the UE supports a multi universal subscriber identification module (MUSIM), and

wherein the releasing of the NAS signaling connection is requested for a first USIM of the UE due to an activity on a second USIM of the UE.

12. The UE of claim 11 , wherein the UE rejects a paging request of the MME.
