Abstract
This disclosure related to the aspects of 5G system that supports Public Land Mobile Network and Non-Pubic Network especially in the context of how the UE (110) can handle multiple subscriptions when connecting to a Non-Public Network.
Claims10
A User Equipment (UE) that has multiple Universal Subscriber Identity Modules (USIM)s, the UE comprising:
- a memory configured to store instructions;
- and
- a processor configured to execute the instructions to:
- handle multiple subscriptions for a Stand-alone Non-Public Network (SNPN);
- select the SNPN based on received System Information including a Public Land Mobile Network identifier (PLMN ID) and a Network identifier (NID) for the SNPN;
- send, to an Access and Mobility Management Function (AMF), a Registration Request message including a Routing Indicator, wherein the AMF routes to a Unified Data Management (UDM) associated with the SNPN based on the Routing Indicator;
- and
- access the SNPN using credentials, the credentials being owned by a credentials holder, the credentials holder being separate from both the UDM and the SNPN.
