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. . | Appendix A List of IMS-related Specifications Introduction 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 http 3GPP Specifications The home page for the 3GPP specifications is http specs If you are looking for the latest specification belonging to a 3GPP Release the entry web page is http ftp Specs latest An archive of all of the versions of a specification is available at http ftp Specs archive A web page that lists all of the 3GPP specifications including their status is stored at http ftp Specs html-info The 3G IP Multimedia Subsystem IMS Merging the Internet and the Cellular Worlds Third Edition Gonzalo Camarillo and Miguel A.
