Claims24
A method of obtaining a call routing number for a mobile station operating in a first wireless telecommunication system, comprising:
- receiving a request to provide a temporary routing number for use in routing a call from outside said first wireless telecommunication system to the mobile station, when said station is located within said first wireless telecommunication system;
- and
- providing in response to the request instead of a temporary routing number, a routing number that had already been assigned to the mobile station when the request was received.
An apparatus for providing a call routing number for a mobile station operating in a first wireless telecommunication system, comprising:
- an input for receiving a request to provide a temporary routing number for use in routing a call from outside said first wireless telecommunication system to the mobile station, when said station is located within said first wireless telecommunication system;
- and
- an output coupled to said input and responsive to the request received at said input for providing instead of a temporary routing number, a routing number that had already been assigned to the mobile station when the request was received.
A private cellular telecommunication network, comprising:
- a mobile station for receiving calls from outside a coverage area of said private cellular network;
- and
- an apparatus for providing a call routing number for said mobile station, including an input for receiving from outside said coverage area a request to provide a temporary routing number for use in routing a call from outside said coverage area to said mobile station within said coverage area, and an output coupled to said input and responsive to said request received at said input for providing instead of a temporary routing number, a routing number that had already been assigned to said mobile station when said request was received when said mobile station is located within said private telecommunication network and when said request originates from outside said private telecommunication network.
