Abstract

Methods and systems to provide a home system with information about a wireless unit roaming in a visited system based on information the wireless unit provides to the visited system. A mobile switching center (MSC-V) of the visited system receives the information from the wireless unit and routes a message to an international gateway. In response, the international gateway creates a new message or alters the original message, and transmits the new or altered message to a mobile switching center (MSC-H) of the home system. In response to receipt of the new or altered message, the MSC-H validates the wireless unit (if valid), creates a response to the new or altered message, and routes the response to the international gateway. The response may include an authorization period for the wireless unit and/or OCOS/TCOS information. In response, the international gateway creates a new response or alters the response, and transmits the new or altered response to the MSC-V. In response to receipt of the new or altered response, the MSC-V registers the wireless unit, provides the wireless unit with communication services in the visited system, or otherwise follows instructions in the new or altered response. If the wireless unit moves to an area served by a second MSC-V, the second MSC-V checks with the international gateway about the wireless unit. If an authorization period is in effect, the international gateway may provide a validation of the wireless unit to the second MSC-V without another message to the home system of the wireless unit.

Claims

1-17. -17. (canceled)

18. In a communications environment wherein a wireless unit has a registration with a first visited switching center, and wherein the wireless unit moves to an area served by a second visited switching center, a method for validating the wireless unit with the second visited switching center, the method comprising:

receiving registration information regarding the wireless unit from the second visited switching center;

determining that an authorization period assigned to the wireless unit is in effect;

sending a validation with respect to the wireless unit to the second visited switching center.

19. The method of claim 18, wherein the registration information is received by a gateway.

20. The method of claim 18, wherein determination that the authorization period assigned to the wireless unit being in effect is made by a gateway.

21. The method of claim 18, wherein the validation is sent by a gateway.

22. The method of claim 18, further comprising:

sending a registration cancellation message to the first visited switching center.

23. The method of claim 22, wherein the registration cancellation message is sent by a gateway.

24. In a communications environment wherein a wireless unit has a registration with a first visited system, and wherein the wireless unit moves to an area served by a second visited system, a method for validating the wireless unit with the second visited system, the method comprising:

receiving registration information regarding the wireless unit from the second visited system;

determining an authorization period assigned to the wireless unit is in effect; and

sending a validation with respect to the wireless unit to the second visited system.

25. The method of claim 24, further comprising:

sending a registration cancellation message to the first visited system.

26. The method of claim 24, wherein the registration information from the second visited system is received at a gateway.

27. The method of claim 24, wherein the second visited system comprises a switching center;

and

wherein the registration information regarding the wireless unit is received from the switching center.

28. The method of claim 24, wherein determination of the authorization period being in effect is made at a gateway.

29. The method of claim 24, wherein the second visited system comprises a switching center;

and

wherein the validation with respect to the wireless unit is sent to the switching center.

30. For use in a communications environment wherein a wireless unit has a registration with a first visited switching center, and wherein the wireless unit moves to an area served by a second visited switching center, a computer-readable medium containing software code that, when executed by a processor, causes the processor to implement a method for validating the wireless unit with the second visited switching center, the method comprising:

receiving registration information regarding the wireless unit from the second visited switching center;

determining that an authorization period assigned to the wireless unit is in effect;

sending a validation with respect to the wireless unit to the second visited switching center.

31. The medium of claim 30, wherein the method is to implement a gateway.

32. The medium of claim 30, wherein the medium contains software code that, when executed by the processor, causes the method executed by the processor to further comprise:

sending a registration cancellation message to the first visited switching center.

33. The medium of claim 32, wherein the method is to implement a gateway.

34. For use in a communications environment wherein a wireless unit has a registration with a first visited system, and wherein the wireless unit moves to an area served by a second visited system, a computer-readable medium containing software code that, when executed by a processor, causes the processor to implement a method for validating the wireless unit with the second visited system, the method comprising:

receiving registration information regarding the wireless unit from the second visited system;

determining an authorization period assigned to the wireless unit is in effect; and

sending a validation with respect to the wireless unit to the second visited system.

35. The medium of claim 34, wherein the medium contains software code that, when executed by the processor, causes the method executed by the processor to further comprise:

sending a registration cancellation message to the first visited system.

36. The medium of claim 34, wherein the method is to implement a gateway.

37. The medium of claim 34, wherein the second visited system comprises a switching center;

and

wherein the registration information regarding the wireless unit is received from the switching center.

38. The medium of claim 34, wherein the second visited system comprises a switching center;

and

wherein the validation with respect to the wireless unit is sent to the switching center.
