Digital cellular telecommunications system (Phase 2+); Universal Mobile Telecommunications System (UMTS); LTE; End-to-end Quality of Service (QoS) concept and architecture (V13.0.0; 3GPP TS 23.207 version 13.0.0 Release 13)
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. The 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 IP 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 of 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 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 interworking to the IM subsystem as well as PSTN and other networks. The document does not cover the circuit switched access services.
