4. A method of a Base Station (BS) for processing a handover complete signal in a multi-hop relay wireless communication system, comprising:
-
determining, upon receipt of a handover complete message for a Mobile Station (MS) that has completed a handover, whether the handover complete message is from a neighbor BS;
deleting information about the MS, if the handover complete message is from the neighbor BS; and
preserving the MS information, if the handover complete message is not from the neighbor BS. - View Dependent Claims (5, 6, 7, 8, 9)

11. A method of a Relay Station (RS) for processing a handover complete signal in a multi-hop relay wireless communication system, comprising:
-
determining whether the RS has determined to preserve information about a Mobile Station (MS), upon receipt of a handover indication message from the MS; and
preserving the MS information for an MS information preservation time period, if the RS has determined to preserve the MS information. - View Dependent Claims (12, 13, 14)

15. An apparatus for processing a handover complete signal in a multi-hop relay wireless communication system, comprising:
-
a Base Station (BS) for transmitting, when a Mobile Station (MS) completes network reentry to the BS, a handover complete message for the MS to at least one of a source node of the MS or a BS of the source node, deleting, upon receipt of a handover complete message from a neighbor BS, information about an MS that has completed a handover associated with the handover complete message, and preserving, upon receipt of a handover complete message from a Relay Station (RS) managed by the BS, information about an MS that has completed a handover associated with the handover complete message; and
an RS for generating a handover complete message and transmitting the handover complete message to a BS, if the MS completes network reentry to the RS, and upon receipt of a handover indication message from an MS, checking whether the RS has determined to preserve information about the MS and preserving the MS information for an MS information preservation time period, if the RS has determined to preserve the MS information. - View Dependent Claims (16)
