The IP Multimedia Subsystem (IMS) Profile for High Definition Video Conference (HDVC) service, documented in this Permanent Reference Document (PRD), defines a minimum mandatory set of features that a video communication client and the network are required to implement to guarantee an interoperable, high quality IMS-based video communication service over fixed and mobile access.
This document describes tests for IMS roaming and for interworking between IMS network operators.
Test configurations are divided into IMS roaming and interworking between two IMS networks.
Terminal testing is the responsibility of the relevant testing groups in 3GPP and the Global
Certification Forum (GCF).
IMS is an internationally recognised standard for evolving GSM mobile networks, designed to ease integration with the Internet and help deliver services across multiple access types (3G, WLAN, WCDMA etc.)
It offers great opportunities for rich multimedia and voice application delivery, yet traditionally has been driven from the network side, with inadequate consideration of the handset interface. OMTP’s recommendations in this area seek to defragment and standardise that interface, address the practicalities of deployment and define the end-to-end experience that is required to enable IMS to deliver on its potential.
This document defines the minimum set of requirements for IMS (IP Multimedia System) functionalities on mobile Terminals and identifies which of these functionalities shall be available for developing new IMS capable applications in the Terminal. 3GPP IMS Release 7 and related service enablers are the scope of this document.
