List of IMS-related Specifications
Throughout this book we have seen many references to specifications that concern the IMS. Sometimes, it is not easy to discover which specifications relate to the IMS and which do not. We have compiled a list of the IMS-related specifications and provide this information to the reader as a guideline. We have tried to make the list as comprehensive as possible, but since new specifications are added, removed, replaced, or renumbered we encourage the reader to check the status of a specification to guarantee it is up to date.
In some cases the whole specification is not devoted to the IMS, just a part of it. The interested reader should analyze which parts are applicable to the IMS.
Finally, we have decided not to list the IETF specifications that are relevant for the IMS, since the list is too large. However, the 3GPP specifications contain references to the IETF documents that are relevant, giving the reader the option to verify the source document. IETF RFCs are available for downloading at the RFC editor web page:
