FIELD: radio engineering, communication.
SUBSTANCE: provided is a first zone and a second zone for wireless communication, the first zone using a first operation mode and the second zone using a second operation mode. The method involves communicating with a mobile station in the first zone using the first operation mode; determining whether the mobile station is capable of operating using both the first operation mode and the second operation mode; and performing, if the mobile station is determined to be capable of operating using both the first and second operating modes, a zone switch procedure to switch the mobile station from the first zone using the first operation mode to the second zone using the second operation mode.
EFFECT: facilitating system switch to transfer a current communication session between an enhanced base station and an enhanced mobile station from the conventional operation mode to an enhanced operation mode.
