IR.34 Guidelines for IPX Provider networks (Previously Inter-ServiceProvider IP Backbone Guidelines)
/strong>The Internet Protocol(IP) Packet eXchange (IPX) Network is an inter-service Provider IPbackbone which comprises the interconnected networks of IPXProviders and General Packet Radio Service (GPRS) Roaming eXchange(GRX) Providers. The purpose of this document is to provideguidelines and technical information on how these networks are setup and interconnect and how service providers will connect to theIPX Provider networks.
IR.39– IMS Profile for High Definition Video Conference (HDVC)Service
The IP MultimediaSubsystem (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 videocommunication client and the network are required to implement toguarantee an interoperable, high quality IMS-based videocommunication service over fixed and mobile access.
IR.95– SIP/SDP Profile for inter-IMS NNI
This document describesa generic SIP/SDP profile for interconnection and roaming NNIbetween operators’ IMS networks for the purposes of exchangingtraffic originating from and terminating to the respectiveoperators’ customers. This document profiles SIP/SDP for theGSMA-defined, IMS-based services (i.e. VoLTE, ViLTE, VoWi-Fi,SMSoIP, and RCS services).
IR.64– IMS Service Centralisation and pddhm/strong>
The 3rd GenerationPartnership Project (3GPP) has specified the solution forcentralisation of services in the IP Multimedia Subsystem (IMS) andof IMS based service continuity in Release 8 onwards. The usershall receive services in a consistent manner when the useraccesses IMS either via the Circuit Switched (CS) or the PacketSwitched (PS) domain. Service continuity is supported between CSand PS domains.
IR.65– IMS Roaming and Interworking Guidelines
The 3rd GenerationPartnership Project (3GPP) architecture has introduced a subsystemknown as the IP Multimedia Subsystem (IMS) as an addition to thePacket-Switched (PS) domain. IMS supports new, IP-based multimediaservices as well as interoperability with traditional telephonyservices. IMS is not a service per se, but a framework for enablingadvanced IP services and apps on top of a packet bearer.
IR.67– DNS/ENUM Guidelines for Service Providers and GRX/IPXProviders
Inter Service ProviderIP communications are starting to evolve to support services otherthan GPRS Roaming. Many, if not all, of these services rely uponDNS. Therefore, it is of utmost importance for the interworking andstability of such services that Service Providers have all thenecessary information to hand to ease configuration of their DNSservers upon which such services rely.
NG.102– IMS Profile for Converged IP Communications
This document defines aprofile that identifies a minimum mandatory set of common IMSfunctionalities that are defined in 3GPP specifications and otherGSMA PRDs that a wireless device (the User Equipment [UE]) andnetwork are required to support in order to guaranteeinteroperable, high quality IMS-based and Mobile Operator providedConverged IP Communications Services (VoLTE, ViLTE, VoWi-Fi andRCS).
