Method and system for providing prepaid roaming support at a visited network that otherwise does not allow it
First Claim
1. A system for providing wireless services to a prepaid subscriber of a Home Public Mobile Network (HPMN) in a Visited Public Mobile Network (VPMN), the HPMN having a Mobile Virtual Network Operator (MVNO), Wireless Intelligent Network (WIN) phase 2 capability, and an associated Home Location Register (HLR), the VPMN having an associated Visited Mobile Switching Center/Visited Location Register (VMSC/VLR), the system comprising:
- a first Signal Gateway (SG) for detecting a registration attempt by the prepaid subscriber at the VPMN;
circuitry for sending a modified registration message to imitate the VPMN'"'"'s roaming support for WIN phase 2 capability;
circuitry for causing the HLR to send a registration acknowledgement message with trigger profile information to the first SG in response to the first modified registration message; and
circuitry for sending a modified registration acknowledgement message to the VMSC/VLR to facilitate the prepaid subscriber'"'"'s mobile communication in the VPMN;
wherein the first SG is coupled to one selected from a group consisting of the VPMN, the HPMN, and the MVNO.

Abstract
The present invention provides a method for providing wireless services to a prepaid subscriber of an HPMN in a VPMN when the prepaid subscriber attempts to register at the VPMN. The method includes detecting at a first Signal Gateway (SG) of one or more SGs, a registration attempt by the prepaid subscriber at the VPMN. The method further includes causing by the first SG, an HLR associated with the HPMN to send a trigger profile information in a registration acknowledgement message to the first SG in response to a modified registration message, sent by the first SG, so as to imitate the VPMN'"'"'s roaming support for WIN phase 2 and the prepaid subscriber'"'"'s registration attempt at the HPMN having a WIN phase 2 support. Finally, the method includes sending a modified registration acknowledgement message by the first SG, to a VMSC/VLR associated with the VPMN to facilitate the prepaid subscriber'"'"'s mobile communication in the VPMN.
