Abstract

A wireless system is equipped for autonomous registration of a wireless telephone when it receives the "on" registration message from the cell site (which contains the telephone number and equipment identification number of the mobile unit), sends such identification of the mobile unit over a data link into a signaling network of the public switch telephone network. The signaling network forwards this data message to a service control point which controls such universal telephone number systems to register the number of the wireless unit for use the next time the universal telephone number is called. Advantageously, the equipment identification number (EIN) also received with the telephone number of the mobile unit may be used as a PIN or general identification number of the subscriber.

Claims

1. A method for use in a telecommunications network, said telecommunications network including a wireless telecommunication system, a signaling network, and a universal telephone number service connected to said signaling network, said universal telephone number service delivering routing telephone numbers responsive to requests for routing information to a subscriber, said method comprising:

responsive to receiving an automatic registration signal from a subscriber'"'"'s mobile unit, said wireless telecommunication system selecting a directory number for said subscriber'"'"'s mobile unit, said wireless telecommunication system sending a message via said signaling network to said universal telephone number service, said message including a telephone number for said subscriber'"'"'s mobile unit;

responsive to receiving said message, said universal telephone number service automatically registering said telephone number for said subscriber'"'"'s mobile unit and changing call routing for said subscriber from a first telephone number corresponding to a first telephone, to the telephone number of said subscriber'"'"'s mobile unit, so that, when a request for call direction arrives at said universal telephone number service, said universal telephone number service delivers the telephone number of said subscriber'"'"'s mobile unit for use in routing a call through said telecommunications network to said subscriber'"'"'s mobile unit; and

responsive to receiving a change request from the subscriber'"'"'s mobile unit, said universal telephone number service changing call routing from the telephone number of said subscriber'"'"'s mobile unit to a second telephone number corresponding to a second telephone, so that, when a request for call direction arrives at said universal telephone number service, said universal telephone number service delivers the second telephone number for use in routing the call through said telecommunications network to said second telephone.

2. A method according to claim 1 wherein said automatic registration signal further includes an equipment identification number, said method further including the step of verifying said equipment identification number before automatically registering said selected telephone number of said subscriber'"'"'s mobile unit.

3. A method according to claim 1 wherein said signaling network comprises an integrated services digital network (ISDN), wherein said step of sending said message comprises sending an ISDN call control message.

4. A method according to claim 1 wherein said wireless telecommunications system includes a protocol converter, wherein said protocol converter receives said message, said step of sending said message on said signaling network comprises said protocol converter sending said message to said universal telephone number service.

5. A method according to claim 4 further including the step of said protocol converter determining that said subscriber subscribes to said universal telephone number service.

6. The method according to claim 1, wherein the second telephone is connected to a landline.

7. The method according to claim 1, wherein the second telephone is connected to a voice mail.

8. The method according to claim 1, wherein the second telephone number is a default number.

9. The method according to claim 1, wherein the step of receiving the change request includes receiving a code sent by said subscriber corresponding to the second telephone number.

10. The method according to claim 1, wherein the automatic registration signal is received when the subscriber turns the mobile unit on and the change request is received when the subscriber turns the mobile unit off.

11. The method according to claim 1, wherein the telephone number of the subscriber'"'"'s mobile unit is identical to a universal telephone number of the subscriber maintained by the universal telephone number service.

12. A method for use in a telecommunications network including a wireless telecommunication system and a number service, said method comprising:

responsive to receiving an automatic registration signal from a subscriber'"'"'s mobile unit, said wireless telecommunication system selecting a directory number for said subscriber'"'"'s mobile unit, said wireless telecommunication system sending a message to said number service, said message including a number for said subscriber'"'"'s mobile unit; and

responsive to receiving said message, said number service changing call routing for said subscriber from a first number corresponding to a first communication unit to the number of said subscriber'"'"'s mobile unit, so that incoming calls for said subscriber are routed through said telecommunications network to said subscriber'"'"'s mobile unit.

13. The method of claim 12, further comprising the steps of:

receiving an automatic change request from said subscriber'"'"'s mobile unit;

responsive to receiving said automatic change request, said wireless telecommunication system sending a message to said number service; and

responsive to receiving said message, said number service changing call routing for said subscriber from said number of said subscriber'"'"'s mobile unit to said first number, so that incoming telephone calls for said subscriber are routed through said telecommunications network to said first communication unit.

14. The method of claim 12, further comprising the steps of:

receiving an automatic change request from said subscriber'"'"'s mobile unit;

responsive to receiving said automatic change request, said wireless telecommunication system sending a message to said number service; and

responsive to receiving said message, said number service changing call routing for said subscriber from said number of said subscriber'"'"'s mobile unit to a second number corresponding to a second communication unit, so that incoming calls for said subscriber are routed through said telecommunications network to said second communication unit.
