From RFC 4006:
3.1. Credit-Control-Request (CCR) Command
The Credit-Control-Request message (CCR) is indicated by the
command-code field being set to 272 and the 'R' bit being set in the
Command Flags field. It is used between the Diameter credit-control
client and the credit-control server to request credit authorization
for a given service.
The Auth-Application-Id MUST be set to the value 4, indicating the
Diameter credit-control application.
Message Format

The table in this section is used to represent which credit-control
applications specific AVPs defined in this document are to be present
in the credit-control messages.
