Currently, frequency vibrations are used to sig- nal an incoming call to the user. Users may require, or desire, more information about the incoming call in order to decide how they wish to proceed. A method for a radio user to distinguish the priority, the type of incoming call, and/or the sender of a call by the frequency of vibrations used to alert the mobile user of the call would provide a greater range of information to the user.
