COMMUNICATION METHOD FOR OFFERING EXTENSION FUNCTIONALITY OF IDENTIFICATION NUMBER ASSOCIATED WITH PARTICULAR MOBILE STATION IN WIRELESS COMMUNICATION SYSTEM

Japanese Patent JP2007124709

A

To convert a format of an IMSI number for performing global roaming capability within a CDMA cellular communication system.

A unique method and apparatus for allowing a wireless communication system to offer increased IMSI number functionality and corresponding global roaming capability by converting an identification number received from a particular mobile station in the wireless communication system in a first format to a second format which allows for use of more information included in the identification number is disclosed. For example, a variable length IMSI number in TIA/EIA/IS-95 format is received at a base station in encoded form. The base station decodes the parameters included in the IMSI number into their original decimal values, and, if all parameters have not been sent in accordance with the IMSI type, will add the proper values to the unsent parameters.
