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. A gateway for providing information about a wireless unit roaming in a visited system, the gateway comprising:

an interface operative to receive a registration message with respect to the wireless unit from the visited system; and

a translator functionally connected to the interface and operative to determine a home system for the wireless unit based on the registration message, to substitute a point code for an element of the home system as a destination point code in the registration message, to cause the registration message to be routed to the home system, and to included an identification of a visited switching center in the visited system in the registration message.

19. The gateway of claim 18, wherein the identification of the visited mobile switching center comprises a mobile switching center identification (MSCID).

20. The gateway of claim 18, wherein the registration message comprises a mobile switching center identification (MSCID) parameter.

21. The gateway of claim 18, wherein the visited system comprises a first visited system;

wherein the wireless unit moves to a second visited system;

wherein the interface is also operative to receive a second registration message from the second visited system;

wherein the translator is operative to use the second registration message to determine that an authorization period assigned to the wireless unit is in effect; and

wherein the translator also is operative to send a validation of the wireless unit to the second visited system.

22. The gateway of claim 18, wherein the registration message comprises a first registration message;

wherein the interface is operative to receive the registration message with respect to the wireless unit from a first mobile switching center of the visited system;

wherein the interface is also operative to receive a second registration message from a second mobile switching center of the visited system;

wherein the translator is operative to use the second registration message to determine that an authorization period assigned to the wireless unit is in effect; and

wherein the translator is also operative to send a validation of the wireless unit to the second mobile switching center.

23. A gateway for providing information about a wireless unit to a visited system, the gateway comprising:

an interface operative to receive a message that includes validation information and anti-fraud information from a home system of the wireless unit;

a translator operative to substitute a point code for an element of the visited system as a destination point code in the message; and

the translator being operative to cause the message to be routed to the element of the visited system.

24. The gateway of claim 23, wherein the anti-fraud information comprises originating service information with respect to the wireless unit.

25. The gateway of claim 23, wherein the anti-fraud information comprises terminating service information with respect to the wireless unit.

26. The gateway of claim 23, wherein the visited system comprises a first visited system;

wherein the interface is also operative to receive a registration message from a second visited system;

wherein the translator is operative to use the registration message to determine that an authorization period assigned to the wireless unit for provision of communication services to the wireless unit is in effect; and

wherein the translator also is operative to send a validation of the wireless unit to the second visited system.

27. The gateway of claim 23, wherein the element comprises a first mobile switching center in the visited system;

wherein the translator is operative to cause the message to be routed to the first mobile switching center;

wherein the interface is operative to receive a registration message from a second mobile switching center in the visited system;

wherein the translator is operative to use the registration message to determine that an authorization period assigned to the wireless unit is in effect; and

wherein the translator also is operative to send a validation of the wireless unit to the second mobile switching center in the visited system.
