ETSI ETSI TS 123 207 V15.0.0 (2018-06)63GPP TS 23.207 version 15.0.0 Release 151 Scope The present document provides the framework for end-to-end Quality of Service involving GPRS and complements TS 23.107 3 which describes the framework for Quality of Service within UMTS. T

29、he end-to-end QoS architecture is provided in Figure 1. The document describes the interaction between the TE/MT Local Bearer Service, the GPRS Bearer Service, and the External Bearer Service, and how these together provide Quality of Service for the End-to-End Service. The document also describes I

30、P level mechanisms necessary in providing end-to-end Quality of Service involving GPRS networks, including possible interaction between the IP level and the GPRS level, as well as the application level and the IP level. This document covers different architectural aspects of the end-to-end Quality o

31、f Service concept and architecture with varying level of detail. In general, other specifications shall be referred to for further details; these other specifications enable the reader to acquire the full understanding of the end-to-end Quality of Service concept and architecture. In particular, the

32、 stage 2 specification for the PCC architecture is specified in TS 23.203 21. The present document does not contain any requirements for the PCC architecture. In contrast to the TS 23.107 3, the present document is only applicable to GPRS packet switched access services, and includes aspects of inte

33、rworking to the IM subsystem as well as PSTN and other networks. The document does not cover the circuit switched access services.

ETSI ETSI TS 123 207 V15.0.0 (2018-06)83GPP TS 23.207 version 15.0.0 Release 153 Definitions and Abbreviations 3.1 Definitions RSVP: Resource ReSerVation Protocol: The RSVP proto

43、col, RFC 2205 9, is used by a host to request specific qualities of service from the network for particular application data streams or flows. The network responds by explicitly admitting or rejecting RSVP requests. DiffServ: DiffServ networks classify packets into one of a small number of aggregate

44、d flows or “classes“, based on the DiffServ codepoint (DSCP) in the packets IP header. This is known as behaviour aggregate (BA) classification (RFC 2475 6). At each DiffServ router, packets are subjected to a “per-hop behaviour“ (PHB), which is invoked by the DSCP (RFC 2474 17). IntServ: The integr

45、ated services architecture RFC 1633 12 defined a set of extensions to the traditional best effort model of the Internet with the goal of allowing end-to-end QOS to be provided to applications. One of the key components of the architecture is a set of service definitions; the current set of services

46、consists of the controlled load and guaranteed services. The architecture assumes that some explicit setup mechanism is used to convey information to routers so that they can provide requested services to flows that require them. While RSVP is the most widely known example of such a setup mechanism,

47、 the IntServ architecture is designed to accommodate other mechanisms. Application Function: The Application Function (AF) is an element offering applications that require the control of IP bearer resources . The AF is capable of communicating with the PCRF to transfer dynamic QoS-related service in

48、formation. One example of an AF is the P-CSCF of the IM CN subsystem. AF session: An AF session is established by an application level signalling protocol offered by the AF that requires a session set-up with explicit session description before the use of the service. One example of an AF session is

49、 an IMS session. AF session signalling: AF session signalling is used to control the AF session. One example of AF session signalling is SIP/SDP. Policy control: The process whereby the Policy and Charging Rules Function (PCRF) indicates to the Policy and Charging Enforcement Function (PCEF) how to control the IP-CAN bearer. Policy control includes QoS control and/or gating control. 3.2 Abbreviations For the purpose of the present document, the following abbreviations apply: AF Application Function APN
