UE, core network node, an node, and methods therefor
A UE ( 1 ) receives, from a network ( 9 , B), control information indicating an association of each of at least one Closed Access Group (CAG) ID with at least one network slice identifier. The UE ( 1 ) performs cell selection or cell reselection using the received control information. This allows the UE to take into account the availability of a network slice in cell selection and cell reselection in the case of a Public network integrated Non-Public Network (PNI-NPN), for example.
1 . A User Equipment (UE) comprising:
at least one memory; and
at least one processor coupled to the at least one memory and configured to:
receive, from a network node, first group information,
wherein the first group information comprises a list of second group information,
wherein each of the second group information comprises an identifier of the second group information and a list of Single Network Slice Selection Assistance Information (S-NSSAI) associated with the second group information, and
wherein a format of the second group information is arranged in order of the identifier of the second group information and thereafter the list of S-NSSAI; and
perform at least one of cell selection or cell reselection.
2 . The UE according to claim 1 , wherein the first group information is used for at least one of cell selection or cell reselection.
3 . The UE according to claim 1 , wherein the network node is an Access and Mobility Management Function and the first group information is included in a Registration Accept message.
4 . A network node for mobility management, the network node comprising:
at least one memory; and
at least one processor coupled to the at least one memory and configured to send, to a User Equipment (UE), first group information,
wherein the first group information comprises a list of second group information,
wherein each of the second group information comprises an identifier of the second group information and a list of Single Network Slice Selection Assistance Information (S-NSSAI) associated with the second group information, and
wherein a format of the second group information is arranged in order of the identifier of the second group information and thereafter the list of S-NSSAI.
5 . The network node according to claim 4 , wherein the first group information is used by the UE for at least one of cell selection or cell reselection.
6 . The network node according to claim 4 , wherein the network node is an Access and Mobility Management Function and the first group information is included in a Registration Accept message.
7 . A method performed by a User Equipment (UE), the method comprising:
receiving, from a network node, first group information,
wherein the first group information comprises a list of second group information,
wherein each of the second group information comprises an identifier of the second group information and a list of Single Network Slice Selection Assistance Information (S-NSSAI) associated with the second group information, and
wherein a format of the second group information is arranged in order of the identifier of the second group information and thereafter the list of S-NSSAI; and
performing at least one of cell selection or cell reselection.
8 . The method according to claim 7 , wherein the first group information is used for at least one of cell selection or cell reselection.
9 . The method according to claim 7 , wherein the network node is an Access and Mobility Management Function and the first group information is included in a Registration Accept message.
10 . A method performed by a network node for mobility management, the method comprising:
sending, to a User Equipment (UE), first group information,
wherein the first group information comprises a list of second group information,
wherein each of the second group information comprises an identifier of the second group information and a list of Single Network Slice Selection Assistance Information (S-NSSAI) associated with the second group information, and
wherein a format of the second group information is arranged in order of the identifier of the second group information and thereafter the list of S-NSSAI.
11 . The method according to claim 10 , wherein the first group information is used by the UE for at least one of cell selection or cell reselection.
12 . The method according to claim 10 , wherein the network node is an Access and Mobility Management Function and the first group information is included in a Registration Accept message.
