Abstract:
1. A network architecture for converging a Push-To-Talk Interoperability Infrastructure (PII) network architecture and an IP Multimedia Subsystem (IMS) network architecture, comprising: a Push-To-Talk Interoperability Infrastructure (PII) network architecture including: an IP Multimedia Subsystem (IMS) network architecture including: wherein the PII network architecture registrar element, session control element, and media element are not coupled to the IMS network architecture registrar element, session control element, and media element; a home subscriber server (HSS) containing a database of subscriber data for subscribers of the PII network architecture and the IMS network architecture coupled to the PII network architecture and the IMS network architecture, wherein the database of subscriber data is shared by the PII network architecture and the IMS network architecture; and an edge proxy coupled to the PII network architecture and the IMS network architecture and used by both the PII network architecture and the IMS network architecture.
