This TR contains a common set of principles, rules and recommendations across 3GPP WGs to ensure Diameter-based interfaces have the same treatment for release control and generating new applications-id. Also to address in a unified manner the use/re-use of AVPs, and other Diameter BASE (see RFC 3588) related decisions.

This TR covers all aspects of Diameter usage within 3GPP, including description of the current situation of Diameter usage in different 3GPP WGs (CT3, CT4, SA5) in Release 6/7, describe recommendations and conditions to re-use existing Diameter applications (3GPP or IETF application-id), commands, AVPs and/or AVP values, describe recommendations and conditions to define new Diameter applications, commands, AVPs and/or AVP values, and any other related issues, e.g. the cross-release issue, whether to apply proposed guideline back to existing Diameter applications or not, or only new SAE Diameter interfaces, etc.

To achieve maximum benefit from this work it is strongly recommended that all 3GPP Diameter-based protocols follow the recommendations in this TR.

This TR also serves a placeholder for Diameter inter-operator considerations with brief guidelines on how to deploy & realize the inter-operator Diameter-based roaming infrastructure.
