Method for handling an idle handoff between base stations supporting different services

摘要

A method for setting a protocol revision value for determining an environment of a service provided by a second base station by a mobile station during a handoff from a first base station to the second base station in an idle state in a mobile communication system including the first base station and the second base station neighboring the first base station, a service supported by the second base station being different from a service supported by the first base station. The mobile station receives an extended system parameter message (ESPM) from the second base station; compares a length of the received ESPM with a length of a preset ESPM; and sets a protocol revision value of the mobile station according to a protocol revision value included in the received ESPM, if the length of the received ESPM is equal to or longer than the length of the preset ESPM.
