A number of VoLTE GSMA Permanent Reference Documents (PRDs) detailed below are available for you to peruse and download here
| IR.92 (VoLTE) – IMS Profile for Voice and SMSThe 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 and IMS-based and SGs-based Short Message Service (SMS) over Long Term Evolution (LTE) radio access. | IR.94 (Video) – IMS Profile for Conversational Video ServiceThe IP Multimedia Subsystem (IMS) Profile for Conversational Video Service, documented in this Permanent Reference Document (PRD), defines a minimum mandatory set of features which are defined in 3GPP specifications that a wireless device and a network are required to implement to guarantee an interoperable, high quality IMS-based conversational video service over Long Term Evolution (LTE) radio access and/or High-Speed Packet Access (HSPA) radio access. The UE and the network may support the video service on either LTE or HSPA access, or on both. |
| IR.34 – Guidelines for IPX Provider networks (Previously Inter-Service Provider IP Backbone Guidelines)The internet Protocol (IP) Packet eXchange (IPX) Network is an inter-Service Provider IP backbone which comprises the interconnected networks of IPX Providers and General Packet Radio Service (GPRS) Roaming eXchange (GRX) Providers. The purpose of this document is to provide guidelines and technical information on how these networks are set-up and interconnect, and how Service Providers will connect to the IPX Provider networks. | IR.39 – IMS Profile for High Definition Video Conference (HDVC) Service
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. |
| IR.58 – IMS Profile for Voice over HSPA
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 High-Speed Packet Access (HSPA) radio access. |
IR.64 – IMS Service Centralization and Continuity GuidelinesThe 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 user shall receive services in a consistent manner when the user accesses IMS either via the Circuit Switched (CS) or the Packet Switched (PS) domain. Service continuity is supported between CS and PS domains. |
| IR.65 – IMS Roaming and Interworking GuidelinesThe 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. IMS supports new, IP-based multimedia services as well as interoperability with traditional telephony services. IMS is not a service per se, but a framework for enabling advanced IP services and applications on top of a packet bearer. | IR.67 – DNS/ENUM Guidelines for Service Providers & GRX/IPX ProvidersInter Service Provider IP communications are starting to evolve to support services other than GPRS Roaming. Many, if not all, of these services rely upon DNS. Therefore, it is of utmost importance for the interworking and stability of such services that Service Providers have all the necessary information to hand to ease configuration of their DNS servers upon which such services rely. |
| IR.88 – LTE Roaming GuidelinesThis document aims to provide a standardised view on how Long Term Evolution (LTE) and Evolved Packet Core (EPC) networks can interwork in order to provide “Next Generation Mobile Network” capabilities when users roam onto a network different from their HPMN. Expectations of the “Next Generation Mobile Network” capabilities are described in the GSMA Project Document: Next Generation Roaming and Interoperability (NGRAI) Project Scope White Paper [16]. |
