随着联通WCDMA精品网络在城区、县城等区域逐渐完善覆盖,用户品牌也得到了稳步提高。但随着用户规模的不断增加,用户对WCDMA网络广覆盖、深覆盖的期望日趋强烈,由此导致的投诉也呈逐渐增加的趋势。由于国内WCDMA网络目前还只能承载在2 GHz频段以及WCDMA网自身多业务的特点,导致WCDMA网络实现广覆盖必然带来成本过高的劣势。因此如何通过在900 MHz的3G UMTS移动通信系统,提高WCDMA网络覆盖能力,减少WCDMA新建站址的需求,加快建设进度,提高网络核心竞争力至关重要。针对UMTS900M系统广覆盖的不同场景提出了几种方案,作为UMTS 900M系统建设方式经验推广和参考。
With China Unicom WCDMA boutique network in the city, county and other regions gradually improve coverage, user brands have also been steadily improved. However, as the size of subscribers continues to increase, users’ coverage of WCDMA networks is becoming stronger and wider. As a result, the number of complaints caused by this service is gradually increasing. As the domestic WCDMA network can only bear the characteristics of its own multi-service in the 2 GHz frequency band and the WCDMA network at present, it is inevitable that the WCDMA network has a high cost because of its wide coverage. Therefore, how to improve the coverage of WCDMA networks and reduce the demand for new WCDMA sites by accelerating the construction progress and improving the core competitiveness of a network through the 900 MHz 3G UMTS mobile communication system is crucial. Several scenarios are proposed for different scenarios covered by the UMTS900M system, which are used as a reference to promote the experience of UMTS 900M system construction.
