ABSTRACT:
A system and method for translating special dialing strings and/or mobile feature codes in a wireless telecommunications network. Upon receipt of a special dialing string ("SDS") or mobile feature code ("MFC"), a mobile switching center passes the SDS or MFC to a centralized processing center. The centralized processing center includes a home location register (HLR) containing an SDS lookup table and/or an MFC lookup table. The SDS lookup table includes information pertaining to the dialed string, a subscriber group number, the mobile switching center group number, and a number to be dialed (translated number). The MFC lookup tables include information pertaining to the dialed string, the subscriber group number, and feature action to be invoked. Using the SDS lookup table in the HLR, an SDS can be translated into a number to be dialed. Using the MFC lookup table, an MFC can be processed to change the mobile subscriber's profile. By using a centralized translation table, SDSs/MFCs originating in a variety of geographic locations can be translated consistently. Additionally, SDS translation can be customized for any particular subscriber, geographic area, or a combination of both. After SDS translation, the number to be dialed may be returned to the mobile switching center. After MFC translation, the appropriate change to the subscriber's profile is made.
