Abstract: Various method and apparatus provides for matching revision levels used by a mobile station (102-104) and a base station (101, 160) for establishing a communication link. The mobile station repeats, for a number of times, the transmission of a request for establishing a communication link between the mobile station and the base station. The mobile station detects failure of establishing the communication link with the first revision level based on repeating the request for the number of times. The mobile station changes the first revision level to the second revision level at the mobile station for establishing the communication link.
