EPC enhancements for proximity services
Abstract
Systems, methods, and instrumentalities are disclosed to describe reporting and/or reacting to a mobility event. A wireless transmit/receive unit (WTRU) may comprise a processor configured, at least in part, to establish a proximity service (ProSe) session with a second WTRU, detect the occurrence of a mobility event in a cellular network while the ProSe session is ongoing, determine a type of action to be performed with respect to the ProSe session based on one or more of the type of mobility event and type of ProSe session, and transmit a notification to a node in the cellular network, wherein the notification includes an indication of an action to be performed on the ProSe session. The node may be one of an evolved Node B (eNB), proximity server, or mobility management entity (MME). The node may be the second WTRU.
