第一步： NodeB首先接收邻小区信号获得邻小区标识。

第三步： GW收到 NodeB上报的所有邻小区标识后， 将所有邻小区标 识定义为本小区邻区集。

本领域内的技术人员根据本发明说明书可以理解， 本发明提出的方案 中， 邻小区的无线信息不限于实施例中的邻小区标识或者邻小区信道质量， 计算邻区集的方法也不限于全部定义和根据信道质量部分定义的方法。本发 明方案不仅可以对邻区集进行自动计算，也可以对小区扰码配置、 小区发射 最大功率配置、 频率配置等进行自动计算。 下面以图 3的网络结构为例， 分 别给出相应的实施例。
在图 3的网络结构下， 可以这样自动计算小区扰码：
第一步： NodeB首先接收邻小区信号获得邻小区扰码以及邻小区信道质 量。
第二步： NodeB根据邻小区扰码以及邻小区信道质量等信息以现有技术 计算本小区扰码。
第二步中所述的现有技术可以利用常用的扰码规划方法， 以 WCDMA 系统为例， 有如下两种方法：
基于扰码组或基于所有不同扰码进行的扰码规划。基于所有不同扰码的 规划是只要满足复用距离的条件下， 把 512个 PSC分配给各个小区。 而基 于扰码组的规划是对每个基站分配一个不同的扰码组，每个基站中的不同扇 区则在这个扰码组 8个不同扰码中选择进行分配。扰码组的复用距离主要是 通过计算信号的载干比 (C/I)来完成。本小区或基站通过对邻区集信号的载干 比 (C/I)的测量， 可以确定复用距离， 从而计算出适合本小区的扰码， 以避免 4尤码干扰。
在图 3的网絡结构下， 可以这样自动计算小区最大发射功率：
第一步： NodeB首先接收邻小区信号获得邻小区信道质量及发射功率等 信息。
第二步： NodeB根据邻小区信道质量及发射功率等信息计算邻区集到达 本小区的路径损耗， 由于路径损耗可逆， 所以根据本小区达到邻区集的干扰 信号的功率上限， 可以计算本小区最大发射功率， 以減少对邻小区的干扰。
选择邻小区最大接收功率做判断， 在选择时， 干扰信号功率就是一个功 率的门限值，它意味着经过自动配置功率的小区到达邻区集的功率经过路径 损耗后不能超过这个功率。
在图 3的网絡结构下， 可以这样自动计算小区频率配置参数：
第一步： NodeB首先接收邻小区信号获得邻小区频率配置信息。
第二步： NodeB根据邻小区频率配置信息计算本小区频率配置参数， 以 避免频率的互干扰， 提高频谱利用率。
其中， 第二步的频谱计算可以采用邻区集频率配置的频率空洞（即未占 用的频率） 。
上述各实施例是 WCDMA 系统中的一个应用。 对于 GSM、 CDMA, Wimax等蜂窝移动通信系统， 以及 WCDMA演进后的系统如 LTE、 4G等可 以采用上述同样的方法。 对于类似 WCDMA的 FDD系统，由于上下行频率不同的，且相互隔断， NodeB普通接收模块只是用来接收和处理上行信号， 而不能接收下行信号。 为了实现本发明的目的， NodeB通常需要配置两套接收机， 分别工作在上、 下行频率上。在本方案第一步中， 小区接收模块需要接收下行信号并完成通 常由终端完成的小区搜索、 解调广播信道、 测量等功能； 在进行下行信号接 收过程中， 本小区的下行发射信号必须短时中断， 以避免干扰。 完成无线参 数自动计算后， NodeB系统可以不再接收下行频率信号。
对于 TD-SCDMA等 TDD系统， 由于上下行频段是相同的， 上述第一 步中的小区搜索模块无需增加配置下行射频通道。 实施步骤相同。
本例所述场景也可以直接或间接适用于采用无执照频段技术（ UMA ) 的适用于家庭和小办公室的小型通信设备和移动式应急通信基站。

所述网络侧设备可以是网关， 或无线网络控制器、 或核心网。
