Systems, methods, and instrumentalities are disclosed to a method of establishing a wireless connection. The wireless connection may be an interface between an eNodeB and a proximity server. The interface may a direct interface between the eNodeB and the proximity server, for example, such that the only node between a wireless transmit/receive 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 S1AP message received from a mobility management entity (MME), an RRC message received from the WTRU, and/or the eNodeB discovering the proximity server. Upon receiving the indication, the eNodeB may establish the interface between the eNodeB and the proximity server. The eNodeB and/or the proximity server may utilize unique session identification to identify the WTRU. |
