Claim:
A method of communicating neighbor base station information in a mobile communication system, the method comprising: receiving, by a neighbor base station, a request message from a serving base station for requesting the neighbor base station information; transmitting, by the neighbor base station to the serving base station, a response message comprising the neighbor base station information, wherein the neighbor base station information includes physical channel information for connecting to the neighbor base station, parameters for an uplink channel descriptor (UCD), and parameters for a downlink channel descriptor (DCD); broadcasting a first neighbor advertisement message comprising the neighbor base station information by the serving base station to all mobile subscriber stations located in a corresponding cell of the serving base station, wherein the first neighbor advertisement message is repeatedly broadcast at a first periodic interval; receiving, by the serving base station from the neighbor base station, a backbone message comprising updated neighbor base station information at each of second periodic intervals to update a change in the neighbor base station information without the serving base station requesting the backbone message, wherein the updated neighbor base station information includes at least updated physical channel information for connecting to the neighbor base station, updated parameters for the UCD or updated parameters for the DCD; and broadcasting a second neighbor advertisement message following the first periodic interval from the serving base station to all the mobile subscriber stations located in the corresponding cell of the serving base station, wherein the second neighbor advertisement message comprises the updated neighbor base station information; wherein the parameters for the UCD comprise first type-length-value (TLV) values of the neighbor base station which are different from first corresponding values of the serving base station, and the parameters for the DCD comprise second TLV values of the neighbor base station which are different from second corresponding values of the serving base station.
