室内外一体化覆盖策略

邓玲

【摘 要】为了研究室内外一体化覆盖策略，对前期仅靠单一室外宏站或室内分布系统等传统的覆盖方式无法解决的室内深度覆盖问题，以及优化扩容困難、负荷过载或者吸收不够等问题，采用网络分层规划的方法分析了室内外一体化覆盖的规划思路，将网络分为布局层、深度覆盖层和吸热层，优化网络结构，实现多手段精准覆盖。同时以居民小区和校园等典型复杂场景为例进行分析，得出合理的室内外一体化多场景、多手段解决策略和覆盖方案，可有效地降低成本，满足用户对高质量无线网络的需求。

Strategy of Indoor and Outdoor Integration Coverage

[Abstract] The only dependence on traditional coverage modes of the outdoor macro station or indoor distribution system cannot deal with the indoor deep coverage， capacity expansion， overload and insufficient absorption. The method of hierarchical planning network was used to analyze the planning idea of the indoor and outdoor united coverage strategy. In the method， networks were divided into layout layer， deep coverage layer and heat absorption layer to optimize network structures and realize accurate coverage. In the meantime， typically complex scenarios such as residential area and campus were exampled to elaborate the indoor and outdoor integrated coverage scheme. The solution and coverage scheme were derived which can effectively reduce the cost and meet the requirements of users for high-quality wireless networks.

互联网+时代来临，用户对移动网络数据速率和容量的需求越来越高，急需普及4G+网络以提供更为个性化的服务，网络的升级和改善迫在眉睫。

随着网络规模不断壮大，网络覆盖问题集中表现出低层室内化、小片区化和零散化等特点，传统的基站和室分建设难以满足当前网络建设和运营成本需要。

为了保证不同业务对用户的感知一致性，必须加强网络在各场景的深度覆盖能力。常规的网络覆盖建设方式有两类：室外基站连续覆盖和室内分布系统。

但从多年网络建设的结果来看，一方面，室外宏基站规模部署后仍然存在大量深度覆盖不足的问题。另一方面，在采用室内分布系统解决深度覆盖问题时，容易出现站址建设困难，深度覆盖不足，优化扩容困难、负荷过载或者吸收不够的问题。……
