Method of using UE discovery for paging optimization
Methods and apparatus are described for refining, e.g., reducing, a paging area corresponding to a user equipment device, e.g., a cellular inactive UE device. Various embodiments are well suited for communications systems in which user equipment devices participate in peer to peer communications networks in which direct user device to user device communications are employed. A user equipment device participating in a peer to peer network transmits discovery signals. A femto base station and/or a cellular active UE device in the local vicinity of the UE device transmitting the peer to peer discovery signal eavesdrops on the peer discovery signaling and detects the presence of the cellular inactive UE device. The detection of the cellular inactive UE device is reported to a MME. The MME determines a paging area corresponding to the detected UE device based on the reported information and the location of the reporting device.
