name: ASR
full_form: Abort-Session- Request
context: The OCF may determine that a service requires termination. The OCF may perform this termination synchronously if it has a CCR pending processing by returning CCA with Result-Code AVP with value DIAMETER-AUTHORIZATION-REJECTED. If the OCF does not have a pending request (asynchronous), the OCF may trigger an ASR to terminate the Diameter session related to the service. On reception of an ASR, the CTF shall close the associated Credit-Control session by sending a CCR [Terminate]. The behaviour of the CTF, in relation to the user session, on reception of an ASR is detailed in the middle-tier TS. As an alternative to the ASR, the OCF may trigger a RAR to which the CTF behaves as described in RFC 4006 [402] and the OCF shall return a CCA with Result-Code AVP with value DIAMETER-AUTHORIZATION-REJECTED for the resulting CCR.
description: The Abort-Session-Request (ASR) is a Diameter message used by the Online Charging Function (OCF) to terminate a Diameter session related to a service. It is sent asynchronously when the OCF does not have a pending request, triggering the Charging Transfer Function (CTF) to close the associated Credit-Control session.
explanation: The text describes ASR as a Diameter message used for terminating sessions, aligning it with the definition of a Diameter Message.
