A method for porting a mobile directory number from one wireless service provider to another

摘要

The present invention is a method for porting a mobile directory number of a subscriber from a donor wireless service provider to a recipient wireless service provider with minimum interruption to the subscriber's wireless communication service. In one embodiment, the present invention is accomplished by creating an entry for the wireless terminal in the recipient wireless service provider's home location register and a temporary pointer in the donor wireless service provider's home location register, wherein such temporary pointer will cause the donor wireless communication system to route or forward any call intended for the wireless terminal being ported to the recipient wireless communications system for completion in well-known fashion. When the porting process is complete, the temporary pointer is removed or deactivated in the donor wireless service provider's home location register. Advantageously, coordination of the porting process is controlled by the recipient wireless service provider resulting in minimum interruption to the subscriber's wireless communications service.
