Comprehensive mobile communications device registration method

In a cellular communication system in which a mobile station in a first coverage area registers and where said mobile station is provided zone information of a first base station corresponding to said first coverage area, a method for re-registration comprising the steps of:

• storing at said mobile station said zone information corresponding to said first base station;
• communicating to said mobile station, by a second base station corresponding to a second coverage area, zone information of said second base station;
• registering by said mobile station with said second base station if said zone information of said second base station is different from said zone information of said first base station;
• and
• setting a timer associated with said stored zone information corresponding to said first base station if said zone information of said second base station is different from said zone information of said first base station.

A method of registering a mobile station in a system of base stations controlled by a system controller wherein each of said base stations communicates with said system controller and wherein said mobile station may establish communication with said system controller through a series of said base stations during a single traffic channel communication, comprising the steps of:

• storing at said mobile station a registration list of information;
• establishing traffic channel communication between said mobile station and said system controller through a first base station;
• detecting termination of the traffic channel communication;
• communicating registration information to said mobile station by a final base station upon detection of the termination of said traffic channel communication wherein said final base station is a base station through which further communication is established at the termination of said traffic channel communication;
• and
• updating at said mobile station said registration list of information in response to said registration information received from said final base station upon termination of said traffic channel communication.
