1. A method for a communication system comprising:

  • controlling a data rate associated with transmission of information from a first base station to a mobile station;

    receiving, by the mobile station, information from the first base station either in a variable rate mode or a fixed rate mode;

    transmitting rate of information from the first base station to the mobile station in the variable rate mode varying between successive data transmit intervals associated with the mobile station;

    transmitting data from the first base station to the mobile station in the variable rate mode until the first base station is unable to receive variable data rate control information from the mobile station;

    attempting, when the first base station is unable to receive the variable data rate control information from the mobile station, at the mobile station to remain in the variable rate mode by searching for a second base station that will support data transmissions to the mobile station in the variable rate mode;

    detecting an ability of the second base station to support data transmissions to the mobile station in the variable rate mode;

    transmitting data from the second base station to the mobile station in the variable rate mode;

    terminating the transmission of data from the first base station to the mobile station in the variable rate mode.
