Should the TSG modify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows:Version x.y.zwhere:xthe first digit:1presented to TSG for information;2presented to TSG for approval;3or greater indicates TSG approved document under change control.ythe second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc.zthe third digit is incremented when editorial only changes have been incorporated in the document.1ScopeThe present document describes the Diameter-based interfaces between the V2X Control Function in the HPLMN and the V2X Control Function in the VPLMN (V6 interface).This specification defines the Diameter application for V6 reference points between the V2X Control Functions. The interactions between the V2X Control Functions are specified.The stage 2 description for V2
