Method and system for providing prepaid roaming support at a visited network that otherwise does not provide 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 Wireless Intelligent Network (WIN) phase 2 capability and an associated Home Location Register (HLR), the VPMN having non-WIN phase 2 capability and an associated Visited Mobile Switching Center/Visited Location Register (VMSC/VLR), the system comprising:
- a Signal Gateway (SG) coupled to the VPMN 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 at the HLR;
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.

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 having a non-WIN phase 2 support. The method includes detecting at a Signal Gateway (SG) coupled to the VPMN, a registration attempt by the prepaid subscriber at the VPMN. The method further includes causing by the SG, an HLR associated with the HPMN to send a trigger profile information in a registration acknowledgement message to the SG in response to a modified registration message, sent by the SG, so as to imitate the VPMN'"'"'s roaming support for WIN phase 2 at the HLR having a WIN phase 2 support. Finally, the method includes sending a modified registration acknowledgement message by the SG, to a VMSC/VLR associated with the VPMN to facilitate the prepaid subscriber'"'"'s mobile communication in the VPMN.

8. A method of providing wireless services to a prepaid subscriber of a Home Public Mobile Network (HPMN) in a Visited Public Mobile Network (VPMN), the HPMN having Wireless Intelligent Network (WIN) phase 2 capability and an associated Home Location Register (HLR), the VPMN having non-WIN phase 2 capability and an associated Visited Mobile Switching Center/Visited Location Register (VMSC/VLR), the method comprising:
-
detecting a registration attempt by the prepaid subscriber at the VPMN via a Signal Gateway (SG);
sending a first modified registration message to imitate the VPMN'"'"'s roaming support for WIN phase 2 capability at the HLR;
sending, via the HLR, a registration acknowledgement message with trigger profile information to the SG in response to the first modified registration message; and
sending a second modified registration acknowledgement message to the VMSC/VLR to facilitate the prepaid subscriber'"'"'s mobile communication in the VPMN. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computer program product comprising a computer usable medium including a computer usable program code stored thereon 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 Wireless Intelligent Network (WIN) phase 2 capability and an associated Home Location Register (HLR), the VPMN having non-WIN phase 2 capability and an associated Visited Mobile Switching Center/Visited Location Register (VMSC/VLR), the computer program product comprising:
-
first computer useable program code means for detecting a registration attempt by the prepaid subscriber at the VPMN via a SG;
second computer useable program code means for sending a first modified registration message to imitate the VPMN'"'"'s roaming support for WIN phase 2 capability at the HLR;
third computer useable program code means for sending, via the HLR, a registration acknowledgement message with trigger profile information to the SG in response to the first modified registration message; and
fourth computer useable program code means for sending a second modified registration acknowledgement message to the VMSC/VLR to facilitate the prepaid subscriber'"'"'s mobile communication in the VPMN.
