Abstract: Methods and apparatus for use in establishing a group session in a mobile network for subscribers associated with a group are described. In one illustrative example, an access and mobility management function (AMF) entity receives, from a user equipment (UE), a request for registration which includes network slice selection assistance information (NSSAI). The NSSAI includes a group identifier associated with a group of subscribers. The AMF entity sends, to a unified data management (UDM) entity, a request for subscriber data which includes the group identifier. The AMF entity receives, from the UDM, a response to the request for subscriber data which includes a plurality of subscriber identifiers corresponding to the subscribers of the group. For a group session, the AMF entity creates a context associated with the group identifier and stores the context locally.

Abstract: Subscription-based, user equipment (UE) event notification techniques for use in a mobile network are described. In one illustrative example, an event subscription request from an application server may be received at a network exposure function (NEF) entity of a 5G mobile network. The event subscription request may include a list of one or more subscribed events for a UE, which may include a UE attach event and/or a UE detach event. A context which indicates the one or more subscribed events may be created for the UE. Sometime during network operation, an indication of an occurrence of an event associated with the UE is received. The indication is received from a policy and charging function (PCF) entity when the UE is configured for IP data delivery, or from an access and mobility management function (AMF) entity when the UE is configured for non-IP data delivery (NIDD).

Abstract: A method is provided in one example embodiment and includes sending, by a first entity associated with an access network, a first request message including a session identifier associated with a user session to a second entity associated with a core network. The method further includes establishing a first control channel with the second entity in which the first control channel is associated with the session identifier. The first control channel is an in-band channel between the first entity and the second entity. The method further includes receiving policy information associated with the user session from the second entity using the first control channel. The policy information is indicative of one or more policies to be applied in the access network to user data associated with the user session.
