Apparatus and method for directing calls to mobile telephone subscribers.

THIS INVENTION PROVIDES A MOBILE COMMUNICATION SYSTEM IN WHICH THE HOME ISSUER OF A MOBILE SUBSCRIBER MAINTAINS AN INDICATION OF INFORMATION WHERE THE MOBILE SUBSCRIBER CAN BE FOUND. WHEN A CALL IS RECEIVED, THE HOME STATIONER SEARCHES THE STATIONER WHERE THE MOBILE SUBSCRIBER IS ASSUMED TO BE LOCATED TO PASS IT, AND THEN REQUESTS THE ANSWER STATIONER (S) TO ORDER THE SUBSCRIBER TO TUNE A VOICE TRAFFIC CHANNEL. ONLY AFTER ALL THIS PROCESS HAS BEEN REACHED, THE RESPONSE ISSUER REPORTS THE HOME STATIONER, WHICH THEN ORDERS THE ISSUE OF THE CALL THROUGH THE NETWORK.
