Abstract: Presented herein are techniques to facilitate that enable notifications to be sent to multiple consumers for Third Generation Partnership Project (3GPP) architectures. In one example, a method is provided that may include obtaining, at a first network entity, a notification subscription message from a second network entity, the notification subscription message comprising a plurality of notification identifiers associated with the second network entity for notifications that are to be communicated to the second network entity, wherein the plurality of notification identifiers are indicated, at least in part, in a header of the notification subscription message; and communicating one or more notifications to the second network entity, wherein the one or more notifications are load-shared among the plurality of notification identifiers associated with the second network entity.

Abstract: A network node includes control plane functionality for managing a session of a user equipment (UE) which is anchored at a User Plane Function (UPF) anchor for communicating traffic between the UE and a data network. The node operates to obtain, from an Access and Mobility Management Function (AMF), a session context request responsive to a handover indication indicating a handover of the session from a Fifth Generation System (5GS) to an Evolved Packet System (EPS). The node identifies whether an uplink classifier (UL-CL) UPF is in use for local offloading to a local UPF anchor for delivery to a local area data network. Based on the identifying, the node obtains uplink tunnel information of the UL-CL UPF instead of the UPF anchor for establishing at least one bearer for the session and sends to the AMF a session context response including the uplink tunnel information of the UL-CL UPF.

Abstract: A method is provided for handling a voice call in a heterogeneous network environment by a wireless device. The method includes sending a registration request to a network node in a Next Generation (5G) network. The wireless device has an existing voice call on a different network in the heterogeneous network environment. The method further includes receiving a registration acceptance from the network node in the 5G network. The registration acceptance indicates that IMS voice services are supported, but existing voice calls are not supported. The method further includes determining to stop an attempt to move the existing voice call to the 5G network.

Abstract: In one embodiment, a method includes: obtaining a RAN preference indicator from an operator indicating whether to use the first RAN or a second RAN for a specified data flow type for a particular user device, wherein the RAN preference indicator is based on subscriber information associated with a user of the particular user device; determining whether to transmit the data flow via the first RAN or the second RAN based on the RAN preference indicator; causing the data flow to be transmitted via the first RAN according to a determination that the RAN preference indicator indicates that the specified data flow type should be transmitted via the first RAN; and causing the data flow to be transmitted via the second RAN according to a determination that the RAN preference indicator indicates that the specified data flow type should be transmitted via the second RAN.
