<p>An improved home location register (HLR) that implements alias mobile ID numbers (MIN) in a mobile telephone system. According to the invention, the improved HLR includes an alias MIN module that comprises an alias MIN table and an alias MIN application program. The alias MIN table associates multiple phone numbers of a cellular phone to the cellular phone's preprogrammed MIN. When the HLR receives dialed digits from an MSC in a location request, the application program uses the dialed digits as key to locate the associated MIN of the receiving party's cellular phone. The retrieved MIN is then included in the routing message and forwarded to the appropriate MSC that currently serves the receiving party's cellular phone. In this way, the subscriber can be reached by dialing any of the pre-associated phone numbers. Therefore, significant convenience is provided to cellular subscribers and wireless service providers.</p> |
