Abstract
A system and method for moving wireless subscribers previously registered with a failed source MSC/VLR or SGSN to a new target MSC/VLR or SGSN in GSM and UMTS networks, using super-charger technology. The present invention allows mobile subscriber IMSIs to be transmitted to a new target MSC/VLR or SGSN before a source MSC/VLR or SGSN fails. Upon failure of the source MSC/VLR or SGSN, the addresses of the source MSC/VLR or SGSN serving the transmitted IMSIs are updated in an HLR and are associated with the addresses of the new target MSC/VLR or SGSN using MAP location update procedures. In another embodiment of the present invention, the addresses of the source MSC/VLR or SGSN servicing mobile subscribers are updated in an HLR to the addresses of the new target MSC/VLR or SGSN without the need for mobile subscribe IMSIs.
