1. A system for communicating between a first communication system having a first signaling protocol and a second communication system having a second signaling protocol, the first signaling protocol not fully compatible with the second signaling protocol, the system comprising:

  • a signaling gateway module, disposed to receive signals from, and positioned outside of, the first and second communication systems, including;

    a first unit, for receiving a first signal transmitted from the first communication system and directed toward said second communication system, and for generating a first request signal requesting first information in response to said first signal;

    a gateway unit, coupled to said first unit, for receiving said first request signal, for determining if said gateway unit includes said first information and if said second communication system includes said first information, for generating a second request signal requesting said first information if said second communication system includes said first information, wherein said first signaling protocol supports a first feature, said second signaling protocol does not support said first feature, said gateway unit further comprising;

    a feature unit, for permitting a mobile station having a home location register in the second communication system to utilize said first feature while communicating via the first communication system; and

    a second unit, coupled to said gateway unit, for receiving said second request signal, for generating a second signal that is compatible with said second signaling protocol, said second signal including a request for said first information, and for transmitting said second signal to the second communication system.
