This is the main part of the message holding the data specific to each Diameter interface.

The Diameter command is wrapped in a XML element marked by <operation/> to make it easy to find the information in the XML. The child of the <operation/> is an XML describing the Diameter command decoded/to be encoded. The tag of the child element is the name of the command.

Each message can only contain a single Diameter command message.

    <operation>
        <InsertSubscriberDataRequest appid="16777251">

        </InsertSubscriberDataRequest>
    </operation>
 </m>

[edit] Parameters

For the XML child containing the command, the following parameters appear as attributes (bold - mandatory, italic - optional)

  • appid: Numeric identifier of the interface to which this message belongs to
  • flags : Diameter flags for the message. For messages on direction TCP aplication -> Diameter translator, flags are optional in requests/answers(they will be added automatically by Diameter), but if they are added, they must be correctly correlated with the tag. An error answer must set flags to error.
  • hhident: Hop-to-hop identifier. Present in messages received by an application server. When an application sends a request, the Diameter translator automatically adds it
  • eeident: End-to-End identifier. Present in messages received by an application server. When an application sends a request, the Diameter translator automatically adds it

For S6a messages, the application ID is 16777251. See S6a/S6d interface.

Non-base protocol Diameter AVPs must have vendor identifier set. For 3GPP AVPs this is 10415.
