a transceiver;
one or more processors communicatively coupled to the transceiver; and
memory, communicatively coupled to the one or more processors, storing instructions executable by the one or more processors individually or collectively to cause the UE to:
identify configuration information comprising at least one first group identifier (ID) of at least one group of servers for authorizing an access to a first standalone non-public network (SNPN),
receive, from at least one base station, first system information including a public land mobile network identifier (PLMN ID), a network identifier (NID) and an indication related to onboarding for a second SNPN, wherein the PLMN ID and the NID are for identifying the second SNPN,
receive, from the at least one base station, second system information including a first list comprising at least one second group ID of at least one group of servers for authorizing an access to the second SNPN,
based on the indication, select the second SNPN, wherein the second SNPN corresponds to the configuration information comprising the at least one first group ID, and
perform registration to the second SNPN.
2 . The UE of claim 1 , wherein the indication is broadcast, in case that onboarding is supported by the second SNPN.
3 . The UE of claim 1 , wherein the memory stores further instructions executable by the one or more processors individually or collectively to cause the UE to:
select the second SNPN based on the second system information.
4 . The UE of claim 1 ,
wherein the at least one first group ID is configured in a combination of a PLMN ID and an NID, and
wherein the at least one second group ID is for supporting the onboarding.
5 . The UE of claim 1 ,
wherein priority information about at least one SNPN is preconfigured in the UE, and
wherein a second list of the at least one first group ID and the preconfigured priority information are updated by a credential server.
6 . A base station in a wireless communication system, the base station comprising:
a transceiver;
one or more processors communicatively coupled to the transceiver; and
memory, communicatively coupled to the one or more processors, storing instructions executable by the one or more processors individually or collectively to cause the base station to:
transmit first system information including a public land mobile network identifier (PLMN ID), a network identifier (NID) and an indication related to onboarding for a first standalone non-public network (SNPN), wherein the PLMN ID and the NID are for identifying the first SNPN,
transmit second system information including a first list comprising at least one first group identifier (ID) of at least one group of servers for authorizing an access to the first SNPN, and
receive, from a user equipment (UE), a request for registration to the first SNPN, wherein the first SNPN corresponds to the indication and configuration information in the UE,
wherein the configuration information comprises at least one second group ID of at least one group of servers for authorizing an access to a second SNPN.
7 . The base station of claim 6 , wherein the indication is broadcast, in case that onboarding is supported by the first SNPN.
8 . The base station of claim 6 ,
wherein priority information about at least one SNPN is preconfigured in the UE,
wherein a second list of the at least one second group ID and the preconfigured priority information in the UE are updated by a credential server, and
wherein the at least one first group ID is for supporting the onboarding.
9 . The base station of claim 6 , wherein the at least one first group ID is configured in a combination of a PLMN ID and an NID.
10 . A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
identifying configuration information comprising at least one first group identifier (ID) of at least one group of servers for authorizing an access to a first standalone non-public network (SNPN);
receiving, from at least one base station, first system information including a public land mobile network identifier (PLMN ID), a network identifier (NID) and an indication related to onboarding for a second SNPN, wherein the PLMN ID and the NID are for identifying the second SNPN;
receiving, from the at least one base station, second system information including a first list comprising at least one second group ID of at least one group of servers for authorizing an access to a second SNPN;
based on the indication, selecting the second SNPN, wherein the second SNPN corresponds to the configuration information comprising the at least one first group ID; and
performing registration to the second SNPN.
11 . The method of claim 10 , wherein the indication is broadcast, in case that onboarding is supported by the second SNPN.
12 . The method of claim 10 , wherein selecting the second SNPN comprises selecting the second SNPN based on the second system information.
13 . The method of claim 10 ,
wherein the at least one first group ID is configured in a combination of a PLMN ID and an NID, and
wherein the at least one second group ID is for supporting the onboarding.
14 . The method of claim 10 ,
wherein priority information about at least one SNPN is preconfigured in the UE, and
wherein a second list of the at least one first group ID and the preconfigured priority information are updated by a credential server.
15 . A method performed by a base station in a wireless communication system, the method comprising:
transmitting first system information including a public land mobile network identifier (PLMN ID), a network identifier (NID) and an indication related to onboarding for a first standalone non-public network (SNPN), wherein the PLMN ID and the NID are for identifying the first SNPN;
transmitting second system information including a first list comprising at least one first group identifier (ID) of at least one group of servers for authorizing an access to the first SNPN; and
