LOCATION BASED METHOD AND SYSTEM FOR WIRELESS MOBILE UNIT COMMUNICATION

摘要

A METHOD AND SYSTEM FOR WIRELESS MOBILE UNIT (402) COMMUNICATION WITHIN A WIRELES NETWORK (405) HAVING GEOGRAPHIC AREAS FOR PREFFERED COMMUNICATION USAGE IS PROVIDED. AN ESTIMATED GEOGRAPHIC LOCATION OF A MOBILE UNIT IS DETERMINED. THE MOBILE UNIT IS PROVIDED WITH RELATIVE POSITION DATA OF AT LEAST ONE PREFFERED COMMUNICATION AREA RELATIVE TO THE DETERMINED MOBILE UNIT (402) ESTIMATED LOCATION. THE MOBILE UNIT IS THEN RELOCATED TO A PREFERRED COMMUNICATION AREA BASED ON THE RELATIVE POSITION DATA. PREFERABLY, A REQUEST FOR A PRE-DESIGNATED PREFFERED COMMUNICATION AREA LOCATION IS INITIATED BY A MOBILE UNIT TRANSMISSION AND RECEIVED BY A NETWORK (405) BASE STATION (406). THE MOBILE UNIT CAN BE EQUIPPED WITH A GLOBAL POSITIONING SYSTEM (GPS) TO DETERMINE THE MOBILE UNIT'S ESTIMATED LOCATION. TRANSMISSION OF ESTIMATED LOCATION DATA CAN BE DEPENDENT UPON WHETHER THE MOBILE UNIT (402) OR THE NETWORK CALCULATES RELATIVE POSITION DATA. (FIGURE 3)
