Section: 16a.4.8 ASA Command
Content: The Abort-Session-Answer (ASA) command, defined in IETF RFC 6733 (Diameter Base) [111], is indicated by the Command-Code set to 274 and the message flags’ ‘R’ bit clear, is sent in response to the ASR. 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. Message Format: <ASA> ::= < Diameter Header: 274, PXY > < Session-Id > { Result-Code } { Origin-Host } { Origin-Realm } [ User-Name ] [ Origin-State-Id ] [ Experimental-Result ] [ Error-Message ] [ Error-Reporting-Host ] [ Failed-AVP ] * [ Redirected-Host ] [ Redirected-Host-Usage ] [ Redirect-Max-Cache-Time ] * [ Proxy-Info ] * [ AVP ] The Experimental-Result AVP contains an Experimental-Result-Code AVP and will signal to the Diameter server that the IP-CAN bearer (e.g. PDP context) has been succesfully terminated as requested. See subclause 16a.6 for the description of the Experimental-Result-Code AVP.
