METHOD FOR STRUCTURING A LATITUDE/LONGITUDE DATA OF HOMEZONE SERVICE IN MOBILE TELEPHONE SYSTEM

摘要

PURPOSE: A method for generating latitude/longitude information in the home zone service of a mobile phone network system is provided to execute home zone service more exactly by determining whether a subscriber terminal is located within a home zone or out of the home zone, without the necessity of installing a special processing part like a GPS processing part. CONSTITUTION: If a call attempt request is generated from a subscriber terminal(310), a mobile phone network system judges whether the terminal is located within a home zone(312). In case that the terminal is located within the home zone, the mobile phone network system makes the call executed through the home zone(314). An MSC(Mobile Station Center) transmits call data to an LDSPC(316). The mobile phone network system analyzes a subscriber call record and updates a home zone list(318). Then the mobile phone network system updates subscriber home zone information(320).
