    14 * Description:  This file contains the header file of the MCbsMcnObserver class.

    15 *

    16 *                MCbsMcnObserver is a mix-in class, which must be implemented

    17 *                by a MCN client class. 

    18 *

    19 *                The sole method of this interface gets called when the MCN state

    20 *                changes. This occurs when a MCN message is received from network

    21 *                and the cell information relayed by the message differs from 

    22 *                the previous cell information.
