1. An apparatus for facilitating intra-cell Peer-to-Peer Communication, comprising:
- at least one antenna configured to receive uplink communications and transmit downlink communications; and
at least one processor, wherein the at least one processor is configured to;
maintain a connection identification (CID) mapping table identifying each communication between two mobile stations, a source mobile station (MS) and a destination mobile station (MS), served by a common network transceiver;
identify first security information associated with an uplink (UL) of the source mobile station (MS) and second security information associated with a downlink (DL) of the destination mobile station (MS);
receive an uplink communication, via the at least one antenna, containing an uplink service data unit (SDU); and
determine if there is a corresponding entry in the CID mapping table and if so, send a downlink communication, via the at least one antenna, containing a corresponding downlink SDU.

Abstract
Methods and systems for providing efficient communications between two mobile stations served by the same base station or relay station are provided. A base station maintains information identifying which mobile stations it is serving. When a connection is set up between two mobile stations, if they are both being served by the same base station, the base station forwards traffic directly between the two mobile stations without forwarding it on to higher level network entities.

8. An apparatus of for facilitating intra-cell communication at a base station, comprising:
-
at least one antenna configured to receive uplink communications and transmit downlink communications; an uplink packet processor; and downlink packet processor; wherein the uplink packet processor is configured to; maintain a connection identification mapping table identifying at least one communication between two mobile stations, a source mobile station (MS) and a destination mobile station (MS), served by a common network transceiver at the relay station; and determine if there is a corresponding entry in the connection identification mapping table; and
wherein the downlink packet processor is configured to send a downlink communication containing a corresponding downlink data unit in response to said determining. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. An apparatus for facilitating intra-cell communication, comprising:
-
at least one antenna configured to receive uplink communications and transmit downlink communications; at least one processor, wherein the at least one processor is configured to; maintain a connection identification mapping table identifying at least one communication between two mobile stations, a source mobile station (MS) and a destination mobile station (MS), served by a common network transceiver; receive, via the at least one antenna, an uplink communication containing an uplink data unit; determine if there is a corresponding entry in the connection identification mapping table and, if so, send a downlink communication containing a corresponding downlink data unit; and continue to serve communications between said two mobile stations, the source mobile station (MS) and the destination mobile station (MS), served by the common network transceiver when the common transceiver loses connection with an infrastructure network. - View Dependent Claims (17)
