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

摘要： A first network node operating in a telecommunications network can receive an authentication request associated with a communication device requesting registration with the telecommunications network. The authentication request can include first subscriber information. The first network node can determine that the first subscriber information includes an anonymous identifier. Responsive to determining that the first subscriber information includes the anonymous identifier, the network node can determine an authentication procedure to be performed. The network node can receive information associated with the communication device as part of the authentication procedure. The network node can generate second subscriber information based on the information associated with the communication device.

摘要： Embodiments of the present disclosure provide methods, apparatus for network function (NF) to support service discovery in a service based architecture. In one embodiment, a method is disclosed to support service discovery using intimacy information and it is performed at a first NF in a network system. In the method, the first NF receives a service discovery request from a second NF, where the service discovery request includes intimacy information of the second NF. The first NF then sends a service discovery response to the second NF, and the service discovery response includes information of the at least one third NF or at least one sub-instance of the third NF.

摘要： Systems and methods are disclosed herein that relate to verifying that a particular Application Function (AF) is authorized to use a particular AF ID in association with an Authentication and Key Management for Applications (AKMA) related procedure in a core network of a cellular communications system. In one embodiment, a method performed by an AKMA Anchor Function (AAnF) in a core network of the cellular communications system for generating a shared secret key for AKMA comprises receiving, directly or indirectly from an AF, a request for a shared secret key for AKMA, the request comprising an AF ID. The method further comprises determining whether the AF is authorized to use the AF ID and performing one or more actions based on a result of determining whether the AF (404) is authorized to use the AF ID.
