Abstract

Example methods, apparatus and articles of manufacture to provide uniform resource identifier (URI) portability for communication networks are disclosed. A disclosed example method includes receiving a first communication session initiation message identifying a called party, identifying a URI associated with the called party, querying a global URI database based on the URI to identify a domain name associated with a service provider network based on the URI, and sending a second communication session initiation message including the URI to the service provider network via the domain name.
