First Claim
1. A method for redirecting roaming traffic of a roamer having a handset, the roamer being associated with a Home Public Mobile Network (HPMN) and initially registered with a first Visited Public Mobile Network (VPMN), the first VPMN coupled to a redirection unit, the method comprising:
- detecting, at the first VPMN, a registration attempt of the roamer at a second VPMN, upon receipt of a first of one or more registration cancellation messages sent by the HPMN;
sending one or more registration messages from the redirection unit to the HPMN; and
causing, based on the one or more registration messages, the HPMN to send a registration response message to a Visited Location Register (VLR) associated with the second VPMN to thwart the registration attempt of the roamer at the second VPMN;
wherein the redirection unit facilitates the roamer'"'"'s mobile communication when the roamer'"'"'s handset is stuck in the second VPMN.

Abstract
The present invention provides a method for redirecting roaming traffic of a roamer associated with an HPMN and currently roaming in a first VPMN. The method includes detecting by a detection unit coupled to the first VPMN, a registration attempt of the roamer at a second VPMN, upon receipt of a first registration cancellation message of one or more registration cancellation messages, sent by the HPMN. Finally, the method includes causing the HPMN to send a registration response message to a VLR associated with the second VPMN, to thwart the registration attempt of the roamer at the second VPMN, by sending one or more registration messages to the HPMN from a redirection unit coupled to the first VPMN. The redirection unit further facilitates the roamer'"'"'s mobile communication when the roamer'"'"'s handset gets stuck in the second VPMN.
