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.
