Method and apparatus for network slice registration
The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-generation (4G) communication system such as long term evolution (LTE). A first method performed by a network entity is disclosed, the method comprising: in case that there is pending network slice selection assistance information (NSSAI) that includes at least one second single NSSAI (S-NSSAI) for a user equipment (UE), receiving, from the UE, a request message including requested NSSAI including at least one first S-NSSAI over a first access type; and transmitting, to the UE, the pending NSSAI including the at least one first S-NSSAI, wherein the at least one first S-NSSAI is different from the at least one second S-NSSAI.
1 . A user equipment (UE) in a wireless communication system, the UE comprising:
a transceiver; and
at least one processor configured to:
transmit, to a network entity, a request message including requested network slice selection assistance information (NSSAI) including at least one first single NSSAI (S-NSSAI) over a first access type, wherein the at least one first S-NSSAI is subject to network slice-specific authentication and authorization (NSSAA), the requested NSSAI does not include any S-NSSAI in a first pending NSSAI for the UE, and the first pending NSSAI includes at least one second S-NSSAI, and
receive, from the network entity, an accept message including a second pending NSSAI including the at least one first S-NSSAI and the at least one second S-NSSAI.
2 . A network entity in a wireless communication system, the network entity comprising:
a transceiver; and
at least one processor configured to:
receive, from a user equipment (UE), a request message including requested network slice selection assistance information (NSSAI) including at least one first single NSSAI (S-NSSAI) over a first access type, wherein the at least one first S-NSSAI is subject to network slice-specific authentication and authorization (NSSAA), the requested NSSAI does not include any S-NSSAI in a first pending NSSAI for the UE, and the first pending NSSAI includes at least one second S-NSSAI, and
transmit, to the UE, an accept message including a second pending NSSAI including the at least one first S-NSSAI and the at least one second S-NSSAI.
3 . The UE of claim 1 , wherein the at least one second S-NSSAI in the first pending NSSAI was requested by the UE over the first access type.
4 . The network entity of claim 2 , wherein the at least one second S-NSSAI in the first pending NSSAI was requested by the UE over the first access type.
5 . A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
transmitting, to a network entity, a request message including requested network slice selection assistance information (NSSAI) including at least one first single NSSAI (S-NSSAI) over a first access type, wherein the at least one first S-NSSAI is subject to network slice-specific authentication and authorization (NSSAA), the requested NSSAI does not include any S-NSSAI in a first pending NSSAI for the UE, and the first pending NSSAI includes at least one second S-NSSAI; and
receiving, from the network entity, an accept message including a second pending NSSAI including the at least one first S-NSSAI and the at least one second S-NSSAI.
6 . The method of claim 5 , wherein the at least one second S-NSSAI in the first pending NSSAI was requested by the UE over the first access type.
7 . A method performed by a network entity in a wireless communication system, the method comprising:
receiving, from a user equipment (UE), a request message including requested network slice selection assistance information (NSSAI) including at least one first single NSSAI (S-NSSAI) over a first access type, wherein the at least one first S-NSSAI is subject to network slice-specific authentication and authorization (NSSAA), the requested NSSAI does not include any S-NSSAI in a first pending NSSAI for the UE, and the first pending NSSAI includes at least one second S-NSSAI; and
transmitting, to the UE, an accept message including a second pending NSSAI including the at least one first S-NSSAI and the at least one second S-NSSAI.
8 . The method of claim 7 , wherein the at least one second S-NSSAI in the first pending NSSAI was requested by the UE over the first access type.
