Abstract: There is provided systems and methods for the grouping of UEs, such that UEs can share a UE group context or share a PDU session context or both. In this manner, network resource usage, with respect to UE context and PDU session context management, can be mitigated.

Abstract: Methods and Systems for modifying or releasing a Multicast/Broadcast (MB) session for delivery of MB Data to a plurality of Electronic Devices (EDs) connected to a (Radio) Access Network (R)AN node is disclosed. The method includes receiving one or more triggers, and instructing the various network functions and (R)AN nodes to modify (or release) the MB session dependent on the received trigger.

Abstract: Methods by which User Plane (UP) management information is exchanged between an Application Function (AF) supporting one or more applications and a Slice Management Function (SMF) configured to manage traffic flows in a given slice of the network. The exchange of UP management information may be initiated from either the AF or the SMF. In the case of AF-initiated information exchange, the UP management information provided by the AF may comprise traffic requirements of applications supported by the AF. In the case of SMF-initiated information exchange, the UP management information provided by the SM may comprise operator policy information or events, and the AF may respond with information of traffic requirements of applications supported by the AF.

Abstract: The present invention provides methods, apparatuses and systems supporting in-order packet delivery during application relocation or UP (User Plane) path management events such as DNAI (Data Network Access Identifier) changes. In-order packet delivery may be enforced, ensured or supported by using an indication that in-order packet delivery is requested or required for a particular traffic flow of a UE during a user plane path management event. The methods may be performed by apparatuses implementing an application function (AF), a policy control function (PCF), a session management function (SMF), or UP entities such as PDU session anchors, of the communication network, or systems implementing a combination thereof. The SMF may configure UP entities to transmit packets and flow end markers to support in-order packet delivery and provide flow end marker information to the UP entities. The UP entities may signal path changes using flow end markers.
