Mobile communication system, compressed-mode controlling method for the same system, and base and mobile stations in the same system

摘要

In a mobile communication system in which a compressed mode can be activated at the time of hand over, or when a base station which the mobile station is in communication with is switched to another base station, the distance between the mobile station and at least one of the plurality of base stations which is currently in communication with the mobile station is measured; and the activation of the compressed mode is controlled according to the measured distance. The activation of a compressed mode is controlled according to the distance between the base station and the mobile station.
