Apparatuses and method for generating and transmitting an anonymous routing identifier to maintain privacy of a SIP user agent's identity

摘要

Apparatus, and an associated method, for generating and transmitting an anonymous GRUU, or other routing identifier, to identify a user agent in a communication system that utilizes SIP signaling. A user agent-generated message is generated that identifies a user agent-request for anonymous operation. And, a SIP registrar, or other network device, operates to provide an anonymous routing identifier that permits anonymous operation of the user agent to maintain privacy of its identity during communications.
