Patent ID: 7525930

Claim:
A system for identity portability across communication systems, comprising: a user communication module, wherein the user communication module is configured to utilize a first communication service provided by a first communication service operator, wherein a network identity is associated with the user communication module, wherein a first network address is associated with the network identity for addressing communications to the network identity via the first communication service, wherein the user communication module is switched to utilize a second communication service provided by a second communication service operator, and wherein a second network address is associated with the network identity for addressing communications to the network identity via the second communication service; and an identity management server module in communication with the user communication module, wherein the identity management server module is configured to map the first network address to the second network address for communications addressed to the network identity at the first network address, wherein the identity management server module is configured to block mapping of the first network address to the second network address to maintain privacy of the network identity after switching to the second communication service provided by the second communication service operator.
