  • Patent number: 6122485
    Abstract: A system and method for confirming the receipt of a message by a messaging unit or pager. The system allows a caller to request page confirmation from the service provider. The system uses a caller identifier, entered by the caller at an input source, and a sequential index to store and locate data relating to the page confirmation request in a data structure. A page confirmation message is sent to the pager and the pager immediately sends a confirmation reply message back to service provider. At this point the service provider indicates in the data structure that the page was successful. At any time, the caller can then access the service provider to determine if his message was received by the pager.

  • Patent number: 6122501
    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.
