1. An apparatus for facilitating communications between a plurality of mobile stations, comprising;
- at least one antenna configured to receive uplink communications and to transmit downlink communications; and
at least one processor coupled to the at least one antenna, wherein the at least one processor is configured to;
maintain a table, wherein the table comprises mobile station identities for the plurality of mobile stations, wherein the plurality of mobile stations includes a first and a second mobile station, and wherein the plurality of mobile stations are served by a common network transceiver;
identify first security information associated with an uplink (UL) of the first mobile station of the plurality of mobile stations and second security information associated with a downlink (DL) of the second mobile station of the plurality of mobile stations;
receive an UL communication, via the at least one antenna, from the first mobile station, wherein the UL communication contains a UL service data unit (SDU); and
send a DL communication, via the at least one antenna, from to the second mobile station, wherein the DL communication contains a DL SDU corresponding to the UL SDU, wherein the DL SDU is routed according to the table.

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.
