Abstract

A system and method of providing communication with a wireless mobile terminal in a wireless communications network having a plurality of wireless communications systems. The method includes sending the mobile terminal'"'"'s MEC between the wireless communications systems in all intersystem messages that contain the MIN for wireless mobile terminal identifiers. This guarantees the successful termination in the system that uses MECs that can support international roaming. The method also includes collecting wireless mobile terminal MECs and correcting incorrect MECs. The system is a wireless communications network for providing communications for a wireless mobile terminal. The network includes a home system, and a visited system, wherein the home system and visited system communicate with each other using revised intersystem messages which include the use of wireless mobile terminal MECs and the MIN for wireless terminal identification in the place of intersystem messages which use just the MIN

Claims

1. A method for providing communication with a wireless mobile terminal in a wireless communications network having a plurality of wireless communications systems, the method comprising:

sending the mobile terminal'"'"'s Mobile Identification Number (MIN) Escape Code (MEC) between the wireless communications systems in all intersystem messages that contain the MIN for wireless mobile terminal identifiers.

2. The method defined in claim 1 wherein autonomous registration is on.

3. The method defined in claim 1 further including paging the wireless mobile terminal in the visited system using the MEC and MIN.

4. The method defined in claim 1 further comprising:

collecting wireless mobile terminal MECs; and

correcting incorrect MECs.

5. The method defined in claim 4 wherein the collecting step includes collecting a wireless mobile terminal'"'"'s MEC in the home system when the wireless mobile terminal is at home or roaming.

6. The method defined in claim 4 further including storing the wireless mobile terminal MEC in the home system.

7. The method defined in claim 4 wherein the correcting step includes manually correcting the incorrect MECs.

8. The method defined in claim 4 wherein the correcting step includes correcting incorrect MECs over the air.

9. The method defined in claim 1 wherein the intersystem messages are ANSI41-type messages.

10. The method defined in claim 1 wherein the wireless communications network is a GSM network.

11. The method defined in claim 1 wherein the wireless communications network is a TDMA network.

12. The method defined in claim 1 wherein the wireless communications network is a CDMA network.

13. A wireless communications network for providing communications for a wireless mobile terminal comprising:

a home system; and

a visited system, wherein the home system and visited system communicate with each other using revised intersystem messages which include the use of wireless mobile terminal Mobile identity number Escape Codes (MECs) and the MIN for wireless terminal identification in the place of intersystem messages which use just the MIN.

14. The wireless communications network defined in claim 13 wherein the home system is a Mobile Switching Center.

15. The wireless communications network defined in claim 13 wherein the home system is a Stand alone Home Location Register.

16. The wireless communications network defined in claim 13 wherein the revised intersystem messages are ANSI41-type messages and the intersystem messages are ANSI41 messages.

17. The wireless communications network defined in claim 13 wherein the wireless communications network is a CDMA network.

18. The wireless communications network defined in claim 13 wherein the wireless communications network is a TDMA network.

19. The wireless communications network defined in claim 13 wherein the wireless communications network is a GSM network.

20. The wireless communications network defined in claim 13 wherein the wireless communications network is a proprietary network.
