Section: 16a.4.3 ACR Command
Content: The ACR command, defined in IETF RFC 6733 (Diameter Base) [111], is indicated by the Command-Code field set to 271 and the ‘R’ bit set in the Command Flags field. It is sent by the GGSN/P-GW to the Diameter server to report accounting information for a certain IP-CAN bearer (e.g. PDP context) or an IP-CAN session of a certain user. The relevant AVPs that are of use for the Gi/Sgi interface are detailed in the ABNF description below. Other valid AVPs for this command are not used for Gi/Sgi purposes and should be ignored by the receiver or processed according to the relevant specifications. The bold marked AVPs in the message format indicate optional AVPs for Gi/Sgi, or modified existing AVPs. For Sgi, some of the optional 3GPP vendor-specific AVPs listed in the message format below are not applicable. See table 9a in subclause 16a.5 to see the ones that are applicable.
