1 A-BDS Support China Telecom June, 2013 Assisted-Beidou
目的:支持移动基站辅助北斗定位方式 China Telecom June, 2013

2 Status and Trends Work Content Work Calendar 2 主要分三个部分介绍:
第一:介绍什么是北斗、中国电信在北斗业务上所做的工作 第二:介绍主要工作的内容 第三:时间计划安排 2

3 BeiDou Navigation Satellite System
GPS GLONASS GALIEO BDS BDS=BeiDou navigation system 和GPS、CLONASS、GALIEO一样都是卫星导航系统

4 Two regional services from BeiDou
Wide range differential service: Positioning accuracy: 1 m Short message service SA/WAAS WAAS EGNOS GAGAN MSAS GNSS Augmentation (BeiDou) 北斗卫星导航系统提供两中服务:广域差分服务以及短信息服务 Augmentation Systems in the world

5 BeiDou service development status and trends analysis
China Telecom has energetically carried out beidou service in industry application field Fishery: Fishery management services Fishing boat services SMS services Transportation : vehicle tracking services Forest Fire Prevention: forest fire detection and monitoring Water conservancy Disaster Prevention and Mitigation Soil Monitoring 美国全球定位系统(GPS) Forest Fire Prevention Fishery Transportation China Telecom BeiDou Service Platform 介绍一下中国电信在北斗业务的开展现状和趋势分析,中国电信建设了北斗业务平台,并大力发展基于北斗的行业应用项目: 渔业,交通,森林防火都是已经开放的业务。 水文水利、防灾减灾以及土壤检测都是将要开放的业务 Core Network 3G Internet M2M

6 A-BDS Support A-BDS is one of the most important services of BDS and becoming the promising usage in the future, especially for cell phones and other handheld units. China telecom has been working on to provide high performance of BeiDou Services Design and implement of A-BDS laboratory system : An A-BDS device may connect to A-BDS server and download positioning information by CDMA radio bearer. China Telecom and vendors have been working together to promote the CDMA A-BDS chip integrated, develop the BeiDou navigation applications based on CDMA devices. A-BD handset international standard? A-BD Server 同时我们也认为,北斗的大规模发展一定是要借助手机这个载体,就如同GPS,正是由于十多年前的美国E911法案启动了消费型GPS第一个成功的里程碑,自此以后,GPS接收器的灵敏度进步了几乎千倍以上,到现如今日手机也已搭配GPS 功能为标准,进而衍生出LBS,2012年,中国位置服务市场规模超过40亿人民币,2013年将突破70亿。 正是看到了北斗的应用发展趋势,所以中国电信对高性能的北斗定位能力提供、北斗和移动互联网融合进行了有益探索,主要方向就是A-beidou,在技术研究时,发现国际标准缺失,一旦标准缺失,会给以后的系统建设造成影响,因为只有通过全球统一、开放的标准,厂商们才可以向用户提供广泛的具有各种竞争能力和互操作性的移动终端和业务,才能并确保整个北斗产业的正循环。所以这也是中国电信要推进3GPP2北斗立项的原因。 另外,中国电信也积极和终端厂商合作推进CDMA终端上集成A-BDS芯片,并开发基于CDMA智能终端的北斗导航应用,以拓展公众市场

7 Status and Trends Work Content 7

8 3GPP2 Work Item Description
Create a new revision of C.S0022 to support Assisted BeiDou Navigation Satellite System (A-BDS) positioning methodology. Update C.S0036-A v1.0 for Position Determination Service for cdma2000 Spread Spectrum Systems C.S0022-B. 主要涉及两个规范C.S0022以及C.S0036 C.S0036 C.S0022

9 Document Introduction
3GPP2 Document ID and Document Name: 3GPP2 C.S0022:“Position Determination Service for cdma2000 Spread Spectrum Systems” 3GPP2 C.R0022: “Position Determination Service for cdma2000 Spread Spectrum Systems Software Distribution” 3GPP2 C.S0036 : “ Recommended Minimum Performance Standard for Mobile Stations with Position Service” The Signal in Space Interface Control Documents (SIS ICDs) of BDS are all freely available (e.g., no registration required): 具体文档名称以及参考的北斗ICD文件,主要工作量就是基于ICD文件更新C.S0022和C.S0036
