Claims41
A method for facilitating mobile number portability, the method comprising:
- receiving a registration message at a signaling gateway (SG) for an International Mobile Subscriber Identity (IMSI) associated with a subscriber, the subscriber being ported-in in a first network and having an original Mobile Station International Subscriber Directory Number (MSISDN) associated with an original network;
- assigning a first (MSISDN) associated with the first network to the subscriber;
- replacing the first MSISDN with the original MSISDN;
- and
- sending, in response to the registration message, a registration response message containing the original MSISDN.
A system for facilitating mobile number portability, the system comprising:
- means for receiving a registration message at a signaling gateway (SG) for an International Mobile Subscriber Identity (IMSI) associated with a subscriber, the subscriber being ported-in in a first network and having an original Mobile Station International Subscriber Directory Number (MSISDN) associated with an original network;
- means for assigning a first (MSISDN) associated with the first network to the subscriber;
- means for replacing the first MSISDN with the original MSISDN;
- and
- means for sending, in response to the registration message, a registration response message containing the original MSISDN.
A computer program product comprising a computer usable medium having control logic stored therein for causing a computer to perform mobile communications, the control logic comprising computer readable program code means for:
- receiving a registration message at a signaling gateway (SG) for an International Mobile Subscriber Identity (IMSI) associated with a subscriber, the subscriber being ported-in in a first network and having an original Mobile Station International Subscriber Directory Number (MSISDN) associated with an original network;
- assigning a first (MSISDN) associated with the first network to the subscriber;
- replacing the first MSISDN with the original MSISDN;
- and
- sending, in response to the registration message, a registration response message containing the original MSISDN.
