Abstract:
1. A method of facilitating intra-cell Peer-to-Peer Communication comprising: maintaining a connection identification (CID) mapping table identifying each communication between two mobile stations served by a common network transceiver, and identifying first security information associated with an uplink (UL) of a source mobile station (MS) and second security information associated with a downlink (DL) of a destination mobile station (MS); and upon receipt by the common network transceiver of an uplink communication containing an uplink service data unit (SDU), determining that there is a corresponding entry in the CID mapping table, decrypting the uplink SDU using the first security information associated with the UL, re-encrypting the uplink SDU using the second security information associated with the DL to produce a corresponding downlink SDU, and sending a downlink communication containing the corresponding downlink SDU.
