full_form: IMS Application Reference Identifier
context: an Accept-Contact header field containing the g.3gpp.iari-ref media feature tag with an IARI value the UE should invoke the IMS application that is the best match for the IARI value. The UE can receive multiple ICSI values, IARI values or both in an Accept-Contact header field. In this case it is up to the implementation which of the multiple ICSI values or IARI values the UE takes action on. NOTE 1: The application verifies that the contents of the request (e.g. SDP media capabilities, Content-Type header field) are consistent with the ICSI value in the g.3gpp.icsi-ref media feature tag and IARI value contained in the g.3gpp.iari-ref media feature tag. If an initial request does not contain an Accept-Contact header field containing a g.3gpp.icsi-ref media feature tag or a g.3gpp.iari-ref media feature tag the UE shall invoke the application that is the best match based on the contents of the request (e.g. SDP media capabilities, Content-Type header field, media feature tag). The UE
description: The IMS Application Reference Identifier (IARI) is a parameter used in the IMS (IP Multimedia Subsystem) to identify and invoke specific applications. It is contained in the Accept-Contact header field of an SIP request and is used by the UE to determine which application to invoke based on the IARI value.
explanation: The context explicitly mentions that IARI is a value contained in the g.3gpp.iari-ref media feature tag, which is used by the UE to invoke specific IMS applications. This indicates that IARI is a parameter used for identifying and selecting applications within the IMS.
