室内环境下多系统多网络的共建共享研究
|
摘要
随着电信运营商重组的完成,新一轮的大规模网络工程建设正式开始。为了切实贯彻国家的节能减排政策,工信部下发了《基础网络资源共建共享》文件。而在基础网络资源建设中,室内覆盖系统消耗了大量的资金成本。对各运营商现行的室内覆盖系统和覆盖方式进行分析,寻找一种共建共享的有效方法,可以减少各运营商的重复投资,降低施工难度,方便网络运营后的维护管理。
室内环境下的多系统多网络的共建共享,是在室内覆盖本身特点的基础上的一种网络建设思路。在目前技术条件下,共建共享主要是分布系统的共建共享,所要重点考虑的重点是各系统之间的杂散干扰(带外干扰)。为了有效抑制杂散干扰,多网合一的共建共享主要通过高隔离度的合路器或POI合路平台实现,必要时把系统上下行分离,以进一步提高系统隔离度,避免各系统间的相互干扰。
本文以广东省某机关大院的多运营商网络统一接入为案例,分析了室内环境下的多系统多网络的共建共享设计应遵循的原则,给出了一种多网合一的设计方法,并对该进行设计了验证,说明所提的设计是可行的。同时论文也总结了所提设计的优点和应用前景,并对其缺点进行了分析,明确了今后的研究方向。
According to the current building structure feature of High Density Cell and mobile communication network feature , further through the analysis of solving programme to mobile communication network in the current High Density Cell, we suggest the solving programme of Wireless Area Centre about in High Density Cell. It means that we adopt relatively concentrated and well-conditioned location to build a central room , and make use of Digital Radio Frequency (RF) Remote System to pull the carrier resources to the designed coverage domain. Also, we integrate the distribution system of cell , the beautified antenna and other ways to cover the high density cell.
Intergrating the particular requests of the solving programme of Wireless Area Centre, though the analysis and comparison to functions of the RF remote equipment in the current market, we suggest using the Digital RF Remote equipment of Frequency Carrier and Frequency Selection among RF Remote equipments in the Wireless Area Centre , and adopting combinations and dispatchions of the Carrier Frequency Resources , the accurate coverage of micro-cell and other mechanisms .In that case, we will make it come up to enhancing the carrier frequency availability, reducing the difficulty of Frequency Planning to the whole network, meeting rapidly-built network of the final-period 3G, reducing degree of difficulty in building network .decreasing the cost of the final-period network operation, improving green environmental protection , reaching the energy conservation and emission reduction and other effects to satisfy the network demand . On the whole , it' s a new type of constructive thinking for the final-period network building.
