IMTDSFDD(WCDMA)系统Gn和Gp接口GPRS隧道协议(GTP)技术规范(R99)IMTDSFDD(WCDMA)TechnicalSpecificationforGPRS(GeneralPacketRadioService)TunnellingProtocol(GTP)acrosstheGnandGpInterface(Release99)(第二稿)前言本规范是在3GPP技术规范TS29.060“3GPPTSGCNGPRS(通用分组无线业务)隧道协议(GTP)Gn和Gp接口(R99)”(2001年12月版本3.b.0)基础上制定的,主要内容与上述标准等效。Gn和Gp接口是指IMTDSFDD(WCDMA)系统核心网络分组域中GSN节点(GPRS支持节点)之间的接口,这是一个开放的系统互联接口。GPRS隧道协议GTP是用于GSN节点之间的接口协议。GTP协议由GTP控制面和用户面协议组成。GTP协议控制平面完成移动台MS接入分组网络的隧道控制和管理功能,消息主要执行建立、修改和删除GSN之间隧道功能,同时还负责GSN节点间的移动性管理、位置管理、路径管理功能。GTP协议用户平面负责数据在隧道中传输,以及传输隧道的部分维护功能。GTP协议用户平面同时使用在WCDMA系统无线子系统和核心网络分组域之间的Iu接口,用于Iu-PS接口用户平面的上层消息的承载。本规范的GTP协议用户面同样适用于Iu-PS。支持计费功能的GTP协议称为GTP’协议GTP’是用于产生计费话单的网络单元(SGSN,GGSN)和计费网关功能单元(CGF)之间的接口协议。GTP’协议基于GTPv0,在3GPP技术规范TS12.15中有详细规定,不在本规范的描述范围之中。GTP’协议的要求为可选。本规范的制定可满足我国WCDMA系统设备开发和引进的需要,保证运营者采用不同厂家(公司)的设备联网时实现互通。本规范由信息产业部电信研究院提出并归口。本规范主要起草单位:信息产业部电信传输研究所华为公司中兴公司本规范主要起草人:孙元宁目次1范围..........................................................................................................................................12参考标准..................................................................................................................................13名词术语和缩略语....................................................................................................................13.1名词术语.............................................................................................................................13.2缩略语................................................................................................................................24综述............................................................................................................................................35传输顺序和比特定义................................................................................................................56GTP字头....................................................................................................................................56.1基本GTP头.......................................................................................................................56.2GTP扩展头......................................................................................................................66.2.1PDCPPDU的序号..................................................................................................87GTP消息和消息格式.............................................................................................................87.1消息格式...........................................................................................................................87.2路径管理消息...................................................................................................................97.2.1回应请求(EchoRequest).....................................................................................97.2.2回应响应(EchoResponse)................................................................................107.2.3版本不支持(VersionNotSupport)....................................................................107.2.4支持扩展包头通知(SupportedExtensionHeadersNotification).....................117.3隧道管理消息.................................................................................................................117.3.1建立PDP上下文请求(CreatePDPContextRequest)....................................117.3.2建立PDP上下文响应(CreatePDPContextResponse)..................................137.3.3更新PDP上下文请求(UpdatePDPContextRequest)....................................167.3.4更新PDP上下文响应(UpdatePDPContextResponse).................................177.3.5删除PDP上下文请求(DeletePDPContextRequest).....................................207.3.6删除PDP上下文响应(DeletePDPContextResponse)..................................207.3.7差错指示(ErrorIndication)..............................................................................217.3.8PDU通知请求(PDUNotificationRequest).....................................................217.3.9PDU通知响应(PDUNotificationResponse)...................................................227.3.10PDU通知拒绝请求(PDUNotificationRejectRequest).................................237.3.11PDU通知拒绝响应(PDUNorificationRejectResponse)..............................237.4位置管理消息.................................................................................................................247.4.1为GPRS发送路由信息请求(SendRouteingInformationforGPRSRequest)247.4.2为GPRS发送路由信息响应消息(SendRouteingInformationforGPRSResponse)...................................................................................................................................257.4.3失败报告请求(FailureReportRequest)...........................................................257.4.4失败报告响应(FailureReportResponse).........................................................267.4.5通知MSGPRS出现请求(NoteMSGPRSPresentRequest)...........................267.4.6通知MSGPRS出现响应(NoteMSGPRSPresentResponse).........................277.5移动性管理消息............................................................................................................277.5.1标识请求(IdentificationRequest)...............................
