Abstract: Systems and methods for session continuity of Multicast Broadcast (MB) Sessions are provided. In some embodiments, a method performed by a base station for session continuity of MB Sessions includes at least one of: providing at least one MB Session to a wireless device connected in 5G; determining that the wireless device is handed over to a target Next Generation Radio Access Network (NG-RAN); and providing session continuity of the at least one MB Session to the wireless device. In some embodiments, being handed over to the target NG-RAN comprises an Xn handover. In some embodiments, being handed over to the target NG-RAN comprises a N2 handover. Some embodiments of the current disclosure provide support for Multicast Broadcast Session continuity (aka “Handover”) at Inter-gNB Xn Handover and Inter-gNB N2 Handover in the 5G NR radio access.

Abstract: Methods are provided to operate an SMF node. A request to create a session for a wireless device is received. A communication establishment request is transmitted to an NEF node responsive to receiving the request to create the session for the wireless device, wherein the communication establishment request includes UPF node information for a tunnel between a UPF node and the NEF node to be used for the session for the wireless device. A communication establishment response is received from the NEF node, wherein the communication establishment response includes NEF node information for the tunnel between the UPF node and the NEF node to be used for the session for the wireless device. A tunnel information update is transmitted to the UPF node after receiving the communication establishment response, wherein the tunnel information update includes the NEF node information for the tunnel between the UPF node and the NEF node.

Abstract: Various embodiments described herein aim to ensure that user data transmissions (e.g., small data transmissions that are sent using control plane messages) do not become excessive and stay infrequent, thereby reducing the likelihood of a network overload situation. In one embodiment, an admission control function (ACF) for regulating the transmission of uplink user data is implemented in a wireless communication device (WCD) (e.g., a CIoT device). Such a WCD device may receive from a core serving node (CSN) admittance information (AI) (e.g., parameters, such as thresholds, used by the ACF to regulate the uplink traffic) that is used in performing the admittance control.

Abstract: Techniques are provided for a UE performing neighbor cell measurement prior to entry into a low power mode. Generally, the UE configures a low energy neighbor cell measurement. Responsive to a low power trigger, the UE delays transition to the low power mode to perform the neighbor cell measurement. The UE enters the low power mode after performing the neighbor cell measurement

Abstract: Systems and methods for wireless device triggered connection resume with early data transmission are disclosed herein. In one embodiment, a method performed by a wireless device for triggering a connection resume with early data transmission comprises sending, to a radio access node, a first Radio Resource Control (RRC) message for resuming an RRC connection of the wireless device. The first RRC message comprises uplink data for early data transmission and Access Stratum (AS) Release Assistance Information (RAI). The AS RAI comprises information that indicates that no subsequent downlink and uplink data are expected, information that indicates that a single subsequent downlink data packet is expected, or information that indicates that multiple subsequent data packets are expected in downlink and/or uplink. The method further comprises receiving a second RRC message from the radio access node.
