摘要
根据LTE网络规划,室外由1.8GHz频段室外站广覆盖,而室内重点或热点场所由2.1GHz频段室分站点覆盖,室内外之间移动,发生的是异频重选及切换。合理设置异频重选及切换参数,可以有效控制异频切换带,更好地保障用户4G业务感知。针对既有宏站主覆盖且负荷高、同时建设有室内分布系统且资源利用率较低的场景,进行具体案例分析和效果验证。
According to the LTE network planning,outdoor by 1.8G band stand wide coverage,indoor hot or focus places covered by2.1G band indoor distribution site,moving between indoor and outdoor,pilot frequency is selected and switches. Based on rational inter-frequency reselection and handover parameter,it can effectively control the different frequency switching bands and ensure the user's 4G business sense. A case analysis and effect verification is carried out on the situation of the main coverage of the existing macro-stations and the high load and the construction of the indoor distribution system and the low resource utilization.
