Abstract:
A method for supporting a handover on the basis of the distance from an intermediate access point to a user equipment includes receiving uplink message set information of the user equipment from a serving base station of the user equipment; receiving the uplink message transmitted by predetermined transmitting power from the user equipment, and detecting the user equipment which has sent the uplink message on the basis of the uplink message set information; determining the receiving power by which said uplink message is received; calculating the distance between the intermediate access point and the detected user equipment by using said predetermined transmitting power and said receiving power; and performing a subsequent handover based on the distance calculated in the previous step.
