Abstract

A method of porting a wireless terminal's directory number from one wireless service provider to another is disclosed. One illustrative embodiment involves creating a temporary pointer in the recipient wireless service provider's Home Location Register that, during the inchoate porting process, directs a call for the directory number to the donor wireless service provider for completion in well-known fashion. When the porting process is complete, the temporary pointer is deactivated and call processing is completed by the recipient wireless service provider in well-known fashion.
