Apparatus, and associated method, for generating and transmitting an anonymous routing identifier to indentify user agent

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.
