Description

射频拉远单元合并小区上行容量提升方法和系统 技术领域
本公开涉及通信技术领域，例如涉及一种射频拉远单元合并小区上行容量提升的方法和系统。
背景技术
随着移动数据业务的发展，信号覆盖以及网络容量等问题，已经成为移动网络运营商日益关注的课题。
相关技术采用基带单元(Baseband Unit，BBU)+射频拉远单元(Remote Radio Unit，RRU)的多通道组网方案，可以快速、有效的解决网络深度覆盖等问题。BBU具有基带资源共享功能，RRU负责信号的收发功能，实现无线网络系统和移动台之间的通信。
BBU和RRU之间通常采用光纤连接，一个BBU可以支持多个RRU，多个RRU可以组成一个小区或者多个小区，在网络部署时，可以选择合适数量的RRU进行合并组成一个小区。
在宽带码分多址(Wideband Code Division Multiple Access，WCDMA)商用网络中，经常采用多个射频拉远单元RRU合并小区的网络部署方案，多个射频拉远单元RRU扇区采用相同的下行扰码加扰，如图1所示。该网络部署方案可以减少小区间的切换或者减少扰码资源规划工作量，节省基带单板配置，适用于例如室内覆盖或者高速公路或铁路沿线。
当多个射频拉远单元RRU合并为一个逻辑小区后，同一逻辑小区的多个扇区采用相同的下行扰码加扰，无线网络控制器(Radio Network Controller，RNC)对小区的上行容量进行控制。理论上来说，小区上行容量负载＝1-(1/RoT)，其中RoT＝RTWP/小区扇区的低噪值。所以，RNC对小区上行容量的控制主要是监测噪声增量(Rise over Thermal noise，RoT)或接收带宽内的总功率(Received Total Wideband Power，RTWP)。传统方案中，为了简化处理，在基带侧，对同一逻辑小区内的所有扇区的RTWP测量量进行比较，取最大的RTWP值上报给RNC。当部分扇区上行容量比较大时会导致其他扇区无法接入或者业务体验差。
发明内容

具体实施方式
下面结合图2-6对本公开进行详细的介绍。
一种射频拉远单元合并小区上行容量提升方法。
在步骤110中，多个RRU连接到基站的BBU，所述多个RRU形成一个逻辑小区。
在步骤210中，多个RRU通过Ir接口上报各自的扇区的RTWP值给BBU，多个RRU的扇区频点相同。
在步骤310中，BBU通过非标准的Iub接口把逻辑小区下的所有扇区的RTWP值上报给无线网络控制器RNC。其中，非标准的Iub接口是相对于标准的Iub接口而言的，标准的Iub接口定义了BBU将一个扇区的RTWP值上报给RNC(例如逻辑小区内所有扇区的RTWP值中的最大值)，而本公开中的BBU将一个逻辑小区内所有扇区的RTWP值上报给RNC，因此使用非标准的Iub接口。
在步骤410中，RNC通过接收到的所述逻辑小区下的每个同频点扇区的RTWP值以及该逻辑小区下的每个扇区的低噪值，计算出所述逻辑小区下每个扇区的噪声增量RoT，根据每个扇区的RoT以及RoT门限来控制每个扇区的上行容量。
可选的，步骤210包括步骤2110和步骤2120。
在步骤2110中，每个RRU测量各自扇区的RTWP值。
