Abstract: A system, apparatus and method are provided for supporting shared sessions in communication networks. The system, apparatus and method include interoperation between a User Equipment and serving nodes of a communication network. The serving nodes communicate with at least one anchor node of the communication network. In some implementations a shared session identifier and User Equipment identifying component are used to identify a User Equipment within a shared session. In some implementations, a paging notification is used to inform one or more target User Equipment that of a downlink message relating to the shared session.

Abstract: Method and apparatus, performed autonomously in a user equipment (UE), for autonomous handover to a target cell of a radio access network (RAN). The method comprises determining, by the UE, an identity of the target cell; receiving, by the UE, a precise time reference broadcast by the target cell, the precise time reference indicating an elapsed time from a predetermined epoch; deriving, by the UE, an uplink timing adjustment based at least in part on the precise time reference, the uplink timing adjustment establishing uplink communication synchronization with the target cell; and transmitting, by the UE, an uplink signal to the target cell in accordance with the derived uplink timing adjustment.

Abstract: A method for slice attachment and configuration, the method comprises: receiving a service request from a user equipment; selecting a second network node to process the service request; receiving a configuration for a network slice to enable the service requested by the user equipment; identifying a first point of presence to receive user plane information corresponding to the network slice; identifying a second point of presence to receive control plane information corresponding to the network slice; forwarding traffic corresponding to the network slice to a third point of presence; transmitting to the user equipment a handle identifying the user equipment context and the network slice configuration; and transmitting to the user equipment a user equipment configuration corresponding to the network slice.

Abstract: A method at a network node of a radio access network (RAN) for managing a context of a user equipment (UE) operating in an inactive mode, the method comprising: receiving, from a second network node, a context retrieval request comprising a UE identifier and a first message, the first message being protected with a first cryptographic key; validating the first message using a stored cryptographic key associated with a UE context indicated by the UE identifier; and sending a context retrieval response message to the second network node containing a relocation indication of whether the UE context is to be relocated to the second network node.
