另外、3GPP和NON-3GPP需要看3GPPR11版本以后的标准，最好看R12或R12以后的协议文档（目前冻结的最高版本为R13）

二、GSMA相关协议文档

A number of the GSMA’s PermanentReference Documents (PRDs) regarding VoWi-Fi, detailed below, areavailable for you to download here.

IR.51–IMS Profile for Voice, Video and SMS over Wi-Fi

This document defines aprofile that identifies a minimum mandatory set of features whichare defined in 3GPP specifications that a wireless device (the UserEquipment [UE]) and network are required to implement in order toguarantee interoperable, high quality IMS-based telephony andconversational video services over Wi-Fi access.

IR.61– Wi-Fi Roaming Guidelines

This document describesthe Wi-Fi Access to the Evolved 3GPP Packet Switched domain alsoknown as the Evolved Packet Core (EPC) as defined in the 3GPPspecifications TS 23.402 and TS 24.302. The document is based on3GPP Release 11 and later. The document also covers policy controland charging and authentication.

IR.34– Guidelines for IPX Provider networks (Previously Inter-ServiceProvider IP Backbone Guidelines)

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 ContinuityGuidelines

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).
