Abstract: A radio access network (RAN) entity (e.g. an eNodeB) may be configured to facilitate multicast communication in a local private Third Generation Partnership Project (3GPP) network. The RAN entity may receive a user data packet tunneled in an IP message via one of a plurality of downlink tunnels. The RAN entity may select, from a plurality of stored mappings, one of a plurality of multicast group identifiers that is mapped to an identified one of a plurality of downlink tunnel endpoint identifiers that matches a downlink tunnel endpoint identifier from a tunnel header of the IP message, as well as one of a plurality of sets of UE identifiers that is mapped to the selected multicast group identifier. The RAN may send, for each one of the UE identifiers in the selected set of UE identifiers, the user data packet for transmission to a UE associated with the UE identifier.

Abstract: The present technology discloses methods, systems, and non-transitory computer-readable storage media for identifying a data communication session within a 5G enterprise network and providing assurance based on the identified data communication session. The present technology provides for establishing a data communication session for user equipment on a 5G network, generating a protocol data unit (PDU) session identifier for the data communication session, and distributing the PDU session identifier to one or more packet core nodes in the 5G network. The PDU session identifier can then be used for collecting one or more key performance indicators in association with the data communication session.

Abstract: A network function is configured to initiate a bulk session cleanup with a single release request. The network function detects a configuration change to a wireless network system that affects multiple user sessions for multiple user devices. The network function generates a single bulk session release request identifying the affected user sessions and provides the single bulk session release request to at least one other network function responsible for the user sessions.

Abstract: In one illustrative example, a user plane function (UPF) may detect initial traffic for an application for a user equipment (UE) for which no current dedicated Quality of Service (QoS) flow is established. In response, the UPF may send, to a control plane function, a message which indicates a request for creating a dedicated QoS Flow for traffic for the application for the UE. The message may include flow metadata and an application identifier obtained in detecting the initial traffic. A QoS Flow may then be created for the traffic based on a selected QoS policy associated with the application identifier. Subsequently, the UPF may determine that a measured time period of traffic inactivity for the QoS Flow is outside a limit set by a threshold. Based on the determining, the UPF may send, to the control plane function, a message which indicates a request for deleting the QoS Flow.
