Abstract: Systems, methods, and software of performing an Authentication and Key Management for Applications (AKMA) authentication service. In one embodiment, an AKMA element (1200) handles an enriched AKMA Key Identifier (A-KID) (800) having an identifier format with a username (802) and a realm (804) separated by an @-symbol (806). The username includes a Routing Indicator (RID) (812), an AKMA Temporary UE Identifier (A-TID) (814), and at least one supplemental character (810) that distinguishes the RID from the A-TID in the username. The AKMA element performs a function of the AKMA authentication service based on the enriched A-KID.

Abstract: Methods, apparatuses, and computer program products are described that support access to multiple mutually exclusive, isolated, and/or disjointed network slices by User Equipment, UE, across one or more networks. The UE connects (1102) to multiple network slices via a Radio Access Network, RAN, by way of one or more Radio Resource Control, RRC, connections. The RRC connections are maintained (1104) between the UE and a respective network slice by switching the connection to inactive or idle when another RRC connection needs to be established. The UE and/or the RAN switches (1106) an RRC connection from an inactive state to an active state based on a trigger condition such as receipt of a notification that downlink data is available over the inactive RRC connection. A Unified Data Management Function, UDM, stores and updates registration state information for the UE and multiple Access and Mobility Management Functions, AMFs.

Abstract: Systems, methods, apparatuses, and computer program products for roaming of multicast MBS services. One method may include receiving, by a user equipment attached to a public land mobile network as an inbound roamer, a service announcement for a broadcast session or service class indicating whether inbound roamers are allowed to access the broadcast service or service class; determining, based on the service announcement, whether the user equipment is allowed to access a broadcast session or service class in the public land mobile network; and in response to determining that the user equipment is allowed to access a broadcast session or service class in the public land mobile network, transmitting, by the user equipment, a multicast/broadcast service interest indication associated with the broadcast session or service class upon completion of a radio resource request.
