Embodiment Construction

[0055] figure 1 A wireless communication network 10 is shown according to some embodiments. Network 10 includes one or more radio access networks (RAN) 14 that wirelessly connect user equipment 12 with one or more core networks (CN) 16, such as one or more public land mobile networks (PLMNs), which The one or more PLMNs include a home PLMN associated with user equipment 12 . The CN 16 in turn connects the user equipment 12 to one or more data networks 18, such as the Internet, the Public Switched Telephone Network (PSTN), or the like.

[0056] The illustrated user equipment 12 may include an integrated circuit card (ICC) 12A. The ICC 12A may be, for example, a Universal Integrated Circuit Card (UICC) executing a Universal Subscriber Identity Module (USIM) application. Regardless, a user device 12 and / or ICC 12A may be associated with a certain subscriber 13 . User equipment 12 and / or ICC 12A may, for example, store, access, or otherwise use a certain subscription identifie...

Abstract

Network equipment (26) in a wireless communication network is configured to receive at least a portion of a subscription concealed identifier, SUCI, (34) for a subscriber (13). The SUCI (34) containsa concealed subscription permanent identifier, SUPI, (20) for the subscriber (13). The received at least a portion of the SUCI (34) indicates a sub-domain code, SDC, (32). The 5 SDC (32) indicates a certain sub-domain, from among multiple sub-domains (30-1, 30-2,...30-N) of a home network of the subscriber (13), to which the subscriber (13) is assigned. The network equipment (26) is also configured to determine, based on the SDC (32) and from among multiple instances (24-1, 24-2, ...24-M) of a provider network function in the home network respectively allocated to provide a service to be consumed for subscribers assigned to 10 different sub-domains, an instance of the provider network function to provide the service to be consumed for the subscriber (13).

Description

technical field [0001] The present application relates generally to wireless communication networks, and more particularly to selecting network function instances in wireless communication networks. Background technique [0002] The next generation (5G) core network (CN) will use a service-based architecture that utilizes service-based interactions between CN network functions (NFs). In this regard, the NF enables other authorized NFs to access its services. As an alternative or in addition to the predefined interfaces defined between network elements, an instance of a NF that consumes a certain type of service needs to query a so-called Network Storage Function (NRF) to discover and communicate with another NF that provides a certain type of service instance to communicate. [0003] Specifically, the NF may act in a provider role as a provider of services (NFp) and / or in a consumer role as a consumer of services (NFc). The NFp instance starts and registers itself with th...
