Abstract
Exemplary embodiments of the present invention are directed to a system and method for user identity portability in communication systems. The present invention can provide user identity portability across communication networks that do not necessarily impose a phone number as the identity, addressing, or routing identifier. According to exemplary embodiments, a user identified by any suitable user identifier can switch network operators (e.g., from operator A to operator B) and retain their user identifier. For example, an identity server can support reverse lookup ENUM usage for URI and other identity correlation. Thus, all communication contacts that the user had while with operator A can seamlessly continue communications with the user even after the user switches to operator B.
