ENHANCED HIGHER LAYER DISCOVERY METHODS FOR PROXIMITY SERVICES

摘要

Systems, methods, and instrumentalities are disclosed to a method of establishing a wireless connection. The wireless connection may be an interiace between an eNodeB and a proximity server. The interface may a direct interface between the eNodeB and the proximity server, for example, such that Ac only node between a wireless transmit/recei ve unit (WTRU) and the proximity server on the interface is the eNodeB. The interface may be a user plane interface. An eNodeB may receive an indication to set up the interface between the eNodeB and the proximity server. The indication may be a SlAP message received from a mobility management entity (M.ME), an RRC.message received from the WTRU, and/or the eNodeB discovenog the proximity server. Upon receiviog the indication, the eNodeB may establish the interlace between the eNodeB and the proximity server. The eNodeB and/or the proximity server may utilize unique session identification to identify the WTRU.
