| 中文摘要 | 中国电信目前运营CDMA2000地面移动通信网络及IPSTAR、LinkStar、BGAN等卫星通信系统。中国电信为了满足移动通信网络建设特殊地段的基站覆盖需求，安排开展CDMA基站基于上述卫星通信系统的卫星链路回传研究、测试工作。\n本论文主要针对CDMA2000网络基站基于IPSTAR卫星通信系统的两种中继回传方案进行测试、分析研究，主要包括：IPSTAR卫星通信测试系统的构建、回传模式比较、测试组网方案、实验室测试分析、现网测试分析等。\n根据中国电信CDMA基站卫星链路回传实验室测试结果，基本验证了卫星链路回传模式的可行性。为了进一步发挥卫星链路回传的优势，研究在特殊场景下（如偏远山区、海岛、沙漠等）如何通过使用卫星链路回传模式以提升CDMA现有网络的覆盖，是一项非常有必要的工作。\n为了解决上述需求，则进一步在实验室测试的基础上开展现网测试，采用针对1x与EV-DO业务支持能力较好的IPSTAR SCPC（Single Channel Per Carrier）卫星回传传输方案，第一次在实际网络（新疆与海南）中测试了以卫星链路作为传输方案的业务性能。根据现场测试结果，以及对试运营期间卫星链路回传基站的主要性能指标分析，IPSTAR的SCPC基站回传方案能满足1x语音和EV-DO数据的业务要求，可作为孤岛组网方式下解决基站传输的一种技术手段。\n本论文中的测试研究结果以及后期设备试运营期间网络维护方面的经验，对于中国电信进一步增进对CDMA网络组网方式与技术的认识都是宝贵的经验。同时可以为集团下一步制定与实施偏远地区CDMA建网策略、丰富突发事件与自然灾害下的应急通信手段，提供有益的数据支撑和决策参考。\n本论文涉及的IPSTAR卫星通信系统主要是由：IPSTAR-1卫星、关口站系统、远端站系统等构成，地面基站为中国电信地面移动网络主要设备供应商：中兴、华为、阿朗的设备。 |
| 英文摘要 | China Telecom currently operates land mobile communication network of CDMA2000, and Satellite Communication System such as IPSTAR, LinkStar and BGAN. In order to fulfill the requirement of particular base stations’services coverage area under mobile network infrastructure, China Telecom have arranged to carry out the CDMA base station’s satellite return link research and test based on Satellite Communication System.\nIn this thesis, CDMA2000 network base station under the IPSTAR satellite communication system mainly based on the two different base station relay signal-return test and research. It includes IPSTAR satellite communication test system infrastructure, transmission model comparison, the test of network construction plans, laboratory test analysis, and actual network test anaylsis and so on.\nAccording to the result of China Telecom’s CDMA base station satellite link laboratory test, the probability of satellite return link mode has been basically approved. In order to develop the satellite return link’s advantage, it’s necessary to research in special environment (such as remote mountain areas, islands and deserts, etc), how to use the satellite return link mode to enhance the CDMA’s network coverage area.\nTo fulfill the above requirement, a further testing in laboratory based on actual network is taken, used for the 1x and EV-DO service with the ability to better support the return IPSTAR SCPC satellite transmission method. For the first time, the actual network (Xinjiang and Hainan) test the satellite link as a transmission scheme of service performance. According to the field test result, as well as the analysis of satellite return link during the trial period of base station as the key performance indicators, IPSTAR’s SCPC base station return method can meet the service requirement of 1x voice and DO data , and it could be used as a base station transmission techniques under sole-island networking solution.\nIn this thesis, the test result and the experience of network maintenance during later trial-operation period had further enhanced the networking knowledge and technology is a valuable experience for China Telecom’s CDMA network.Moreover,it can provide useful data support and decision-making for corporation’s reference to both develop and implement CDMA network construction solutions in remote area, and enrich handling solutions in emergency incidents and natural disasters.\n\nIPSTAR satellite communications system in this thesis is mainly involved:IPSTAR-1 satellite, Satellite Gateway System, a remote site system, etc., and main China Telecom ground station equipments suppliers: ZTE, Huawei and Alcatel-Lucent. |
