京广高铁WCDMA异频组网应用研究

摘要

According to the interference in Beijing-Guangzhou high-speed railway WCDMA network, Beijing Unicom proposes the solution of differ-frequency networking according to the characteristics of the WCDMA network, and analyzes different allocation strategies in differ-frequency networking in various situations, such as waiting room/station, high-speed railway line, the provincial boundary, etc. By using the allocation strategy in the differ-frequency networking, network interference and power congestion can be well alleviated.%针对目前京广高铁WCDMA网络暴露出来的网内干扰问题，北京联通根据网络自身特点，提出了异频组网解决方案，并从异频组网在候车室/站台、高铁沿线、省际边界等各种场景下的不同配置策略展开分析，通过采用针对性的异频组网配置策略，可以很好地解决网络干扰和功率拥塞问题。
