The IP Multimedia Subsystem (IMS) Profile for Conversational Video Service, documented in this Permanent Reference Document (PRD)
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).
IR.65 gives common guidelines for IMS (IP Multimedia Subsystem as specified by 3GPP) inter-operator connections in order to prevent non-interoperable and/or inefficient IMS services & networks. Areas covered in the document are IMS specific issues in roaming and interworking, addressing of users and network elements, routing of traffic, inter-operator related security issues, IP version usage and requirements for inter-PLMN backbone caused by IMS. Document concentrates on the network level issues.
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.
The 3rd Generation Partnership Project (3GPP) has specified the solution for centralization of services in the IP Multimedia Subsystem (IMS) and of IMS based service continuity in Release 8 onwards.
The 3rd Generation Partnership Project (3GPP) architecture has introduced a subsystem known as the IP Multimedia Subsystem (IMS) as an addition to the Packet-Switched (PS) domain.
The IP Multimedia Subsystem (IMS) Profile for Voice and SMS, documented in this Permanent Reference Document (PRD), defines a profile that identifies a minimum mandatory set of features which are defined in 3GPP specifications that a wireless device (the User Equipment (UE)) and network are required to implement in order to guarantee an interoperable, high quality IMS-based telephony service over Long Term Evolution (LTE) radio access.
