A handover method in a communication system comprised of a serving BS, a Subscriber Station, SS, and a plurality of neighbor BSs adjacent to the serving BS, comprising the steps of: transmitting, from the serving BS to the SS, information of the neighbor BSs; measuring at the SS a Carrier to Interference Noise Radio, CINR, of a pilot signal of the neighbor BSs 1; receiving, by the serving BS from the SS, a handover request message having the CINR information of pilot signals of the neighbor BSs; arranging by the serving BS, the neighbor BSs according to magnitude of the CINR information 2; transmitting from the serving BS to the neighbor BS having the greatest CINR from among the arranged neighbor BSs 3 a request message related to handover for the SS, where the request message includes information of the SS; receiving, at the serving BS, from the neighbor BS having the greatest CINR from among the arranged BSs a response message including information of determining whether the neighbor BSs supports the handover for the SS or not in response to the request message; if the neighbor BS having the greatest CINR from among the arranged neighbor BSs 1 page 26, line 27 to page 27, line 2; "...measures a CINR of a pilot signal... at Step 1006...returns to Step 1006." 2 page 21, lines 12-15 and page 27, lines 32-33: "arranges neighbor BSs...a variety of possible methods for arranging, "arranges CINR....magnitude." 3 page 28, lines 10-12: "transmits to the neighbor BS having the greatest CINR..." does not support the handover, transmitting, from the serving BS, the request message related to handover for the SS to a neighbor BS with the second greatest CINR from among the arranged neighbor BSs 4; and transmitting from the serving BS to the SS in response to the handover request message, a handover response message having information on a target BS supporting the handover 5. transmitting, from the serving BS to the SS, information of the neighbor BSs; measuring at the SS a Carrier to Interference Noise Radio, CINR, of a pilot signal of the neighbor BSs 1; receiving, by the serving BS from the SS, a handover request message having the CINR information of pilot signals of the neighbor BSs; arranging by the serving BS, the neighbor BSs according to magnitude of the CINR information 2; transmitting from the serving BS to the neighbor BS having the greatest CINR from among the arranged neighbor BSs 3 a request message related to handover for the SS, where the request message includes information of the SS; receiving, at the serving BS, from the neighbor BS having the greatest CINR from among the arranged BSs a response message including information of determining whether the neighbor BSs supports the handover for the SS or not in response to the request message; if the neighbor BS having the greatest CINR from among the arranged neighbor BSs 1 page 26, line 27 to page 27, line 2; "...measures a CINR of a pilot signal... at Step 1006...returns to Step 1006." 2 page 21, lines 12-15 and page 27, lines 32-33: "arranges neighbor BSs...a variety of possible methods for arranging, "arranges CINR....magnitude." 3 page 28, lines 10-12: "transmits to the neighbor BS having the greatest CINR..." does not support the handover, transmitting, from the serving BS, the request message related to handover for the SS to a neighbor BS with the second greatest CINR from among the arranged neighbor BSs 4; and transmitting from the serving BS to the SS in response to the handover request message, a handover response message having information on a target BS supporting the handover 5.
