The Essence of OMA PoC 1.0
The OMA PoC 1.0 standard is built in cooperation with the IP Multimedia Subsystem (IMS) standard as defined by 3GPP and IETF specifications. OMA has defined the evolution path of the OMA PoC standard as the current 1.0 release and a 2.0 release now in development.
OMA PoC 1.0 is a collection of six specifications: Requirements, Architecture, Signaling Flows, Group/List Management, and two User-plane specifications (Transport and GPRS). Together they form a complete set of specifications for an IP-based PTT application. OMA PoC 1.0 was ratified and approved by OMA members in June 2006.
OMA PoC 2.0 extends the network architecture and presence-enabled user experience of OMA PoC 1.0 to additional “Push-to-X” applications, including Push-to-Voicemail and Push-to-Video Stream, both of which will be powerful communication tools for enterprises and their field force organizations.
