2.11.5 AVP Dictionaries

The GUI driven definition is much simplified by using AVP names instead of AVP codes wherever possible. The Diameter Mediation Framework includes a Base AVP Dictionary where well known AVPs are defined. This dictionary includes AVPs defined in the base Diameter Protocol and AVPs defined by popular applications such as Diameter Credit Control Application, and S6a interface. Any additions made by the operator are included into the Custom AVP Dictionary. Once defined, these AVPs are available for use by their name during rule template defnition.

A grouped or non-grouped AVP defined in the base dictionary or in the custom dictionary can be cloned, modified and saved into the customer dictionary. An AVP cannot be saved if the combination of the same AVP code and/or AVP name already exists in the custom dictionary. If the user clones an AVP that is referred from some template/rule, then the GUI only allows adding new sub AVPs to the grouped AVP, no other changes are allowed. If the AVP is not used by any template/rule, the user can do other modifications.
