With the exception of HTTP redirect override, overrides cannot be removed by the Charging-Rule-Remove AVP. They can only be overridden, and consequently the Charging-Rule-Remove AVP is ignored. It is ignored only for regular overrides and not for PCC rules (see PCC rules) or for HTTP redirect override. An HTTP redirect override can be removed whether it is active (a filter with HTTP redirect action is applied) or inactive (a filter without HTTP redirection is applied).
Charging-Rule-Remove ::= < AVP Header: 1002 >
Charging-Rule-Name = v4-http-url:<name>
Charging-Rule-Name = v6-http-url:<name>
The name string in the CRN AVP is ignored in the context of HTTP redirect override. This means that the removal of HTTP redirect override with any name removes the currently installed HTTP redirect override.
Similarly, the installation of the HTTP redirect override replaces any currently installed HTTP redirect override, regardless of the name string (implicit removal of the current HTTP redirect override, followed by the installation of the new one).
The node replies with RAA=OK if a properly formatted Charging-Rule-Remove directive with any name is received for HTTP redirect override.
