Method and system to determine service in incoming message
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The present subject matter refers to a method for a user equipment (UE) including a multi-universal subscriber identity module (MUSIM) in a wireless communication system is provided. The method includes registering to a public land mobile network (PLMN) on both of a 3rd generation partnership project (3GPP) access network and a non-3GPP access network, receiving, from an access and mobility management function (AMF), a message while the 3GPP access network is in an idle state, in case that the message is received over the 3GPP access network, identifying the message is related to a voice service and in case that the message is received over the non-3GPP access network, identifying that the message is related to a non-voice service.
1. A method for a user equipment (UE) including a multi-universal subscriber identity module (MUSIM) in a wireless communication system, the method comprising:
performing a registration operation to a public land mobile network (PLMN) on both of a 3 rd generation partnership project (3GPP) access network and a non-3GPP access network;
receiving, from an access and mobility management function (AMF), a notification message over the non-3GPP access network; and
transmitting, to the AMF, at least one of: a service request message over the 3GPP access network and a notification response message, over the non-3GPP access network, indicating inability of the UE to send the service request message.
2. The method of claim 1 , further comprising:
receiving, from the AMF, a paging message over the 3GPP access network,
wherein the paging message is related to a voice service.
3. The method of claim 1 , wherein the inability of the UE to send the service request message is due to a UE implementation constraint.
4. The method of claim 1 , wherein
the notification message is received in case that:
the UE supports a paging cause indication,
the UE is indicated by the AMF that a paging indication for a voice service is supported, and
the AMF identifies that downlink data for the UE is related to a non-voice service.
5. The method of claim 1 , wherein the notification message is received over the non-3GPP access network while the 3GPP access network is an idle state.
6. A method for an access and mobility management function (AMF) in a wireless communication system, the method comprising:
transmitting, to a user equipment (UE), a notification message over a non-3rd generation partnership project (3GPP) access network; and
receiving, from the UE, at least one of: a service request message over a 3GPP access network and a notification response message, over the non-3GPP access network, indicating inability of the UE to send the service request message,
wherein the UE is registered to a public land mobile network (PLMN) on both of the 3GPP access network and a non-3GPP access network.
7. The method of claim 6 , further comprising:
transmitting, to the UE, a paging message over the 3GPP access network,
wherein the paging message is related to a voice service.
8. The method of claim 6 , wherein the inability of the UE to send the service request message is due to a UE implementation constraint.
9. The method of claim 6 , wherein the notification message is received in case that:
the UE supports a paging cause indication,
the UE is indicated by the AMF that a paging indication for a voice service is supported, and
the AMF identifies that downlink data for the UE is related to a non-voice service.
10. The method of claim 6 , wherein the notification message is transmitted over the non-3GPP access network while the 3GPP access network is an idle state.
11. A user equipment (UE) including a multi-universal subscriber identity module (MUSIM) in a wireless communication system, the UE comprising:
a communication circuit; and
at least one processor coupled to the communication circuit, the at least one processor configured to:
perform a registration operation to a plublic land mobile network (PLMN) on both of a 3 rd generation partnership project (3GPP) access network and a non-3GPP access network,
receive, from an access and mobility management function (AMF), a notification message over the non-3GPP access network; and
transmit, to the AMF, at least one of: a service request message over the 3GPP access network and a notification response message, over the non-3GPP access network, indicating inability of the UE to send the service request message.
12. The UE of claim 11 , wherein the at least one processor is further configured to:
receive, from the AMF, a paging message over the 3GPP access network, and
wherein the paging message is related to a voice service.
13. The UE of claim 11 , wherein the inability of the UE to send the service request message is due to a UE implementation constraint.
14. The UE of claim 11 , wherein the notification message is received over the non-3GPP access network while the 3GPP access network is an idle state.
15. The UE of claim 11 , wherein the notification message is received in case that:
the UE supports a paging cause indication,
the UE is indicated by the AMF that a paging indication for a voice service is supported, and
the AMF identifies that downlink data for the UE is related to a non-voice service.
16. An access and mobility management function (AMF) in a wireless communication system, the AMF comprising:
a communication circuit; and
at least one processor coupled to the communication circuit, the at least one processor configured to:
transmit, to a user equipment (UE), a notification message over a non-3 rd generation partnership project (3GPP) access network, and
receive, from the UE, at least one of: a service request message over a 3GPP access network and a notification response message, over the non-3GPP access network, indicating inability of the UE to send a service request message,
wherein the UE is registered to a public land mobile network (PLMN) on both of the 3GPP access network and a non-3GPP access network.
17. The AMF of claim 16 ,
wherein the at least one processor is further configured to:
transmit, to the UE, a paging message over the 3GPP access network, and
wherein the paging message is related to a voice service.
18. The AMF of claim 16 , wherein the inability of the UE to send the service request message is due to UE implementation constraint.
19. The AMF of claim 16 , wherein:
the notification message is received in case that:
the UE supports a paging cause indication,
the UE is indicated by the AMF that a paging indication for a voice service is supported, and
the AMF identifies that downlink data for the UE is related to a non-voice service.
20. The AMF of claim 16 , wherein the notification message is received over the non-3GPP access network while the 3GPP access network is an idle state.
