Foreword This Technical Specification (T

25、S) has been produced by ETSI Technical Committee Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN). ETSI ETSI TS 183 017 V3.2.1 (2010-02)61 Scope The present document provides the stage 3 specification of the Gq interface. The functional requirements a

26、nd the stage 2 specifications of the Gq interface are contained in ES 282 001 1 and ES 282 003 2. The Gq interface is the interface between the Application Function (AF) and the Service Policy Decision Function (SPDF) and is used for session based policy set-up information exchange between the SPDF

27、and the AF. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For a specific reference, subsequent revisions do not apply. Non-specific reference may be made only to a complete document or a part thereof and only

ETSI ETSI TS 183 017 V3.2.1 (2010-02)83 Definitions and abbreviations 3.1 Definitions For the purposes of the present document, the following terms and definitions apply: Application Function (AF): element offering applications that require the control

44、 of IP bearer resources NOTE: The AF is capable of communicating with the SPDF to transfer dynamic QoS-related application information. One example of an AF is the P-CSCF of the IMS. AF session: established by an application level signalling protocol offered by the AF that requires a session set-up

45、with explicit session description before the use of the service NOTE: One example of an application session is an IMS session. AF session signalling: used to control the AF session NOTE: One example of AF session signalling is SIP/SDP. Attribute-Value Pair (AVP): Information Element in a Diameter me

46、ssage NOTE: See RFC 3588 3. hard-state reservation: type of reservation whereby the requested resources are reserved without time limit NOTE: Hard-state reservations are terminated when the DIAMETER session is terminated. soft-state reservation: type of reservation whereby the requested resources ar

47、e reserved for a finite amount of time NOTE: Soft-state reservations are terminated if the DIAMETER session is terminated. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: AAA AA-Answer AAR AA-Request AF Application Function A-RACF Access-RACF ASA Abort-
