在一些可行的实施方式中，冲突检测模块 42可根据接收的二阶邻区的 Prach Configuration信息、 自身配置的 Prach Configuration信息以及根据各小区的邻区 关系进行二阶邻区的 Prach冲突检测。 比如， 冲突检测模块 42可将自身的二阶 邻区的 Prach Configuration信息中的根序列索引信息（ Root Sequence Index )与 接收的二阶邻区的 Prach Configuration信息中的根序列索引信息（ Root Sequence
Index )进行比较， 如果二者相同， 则证明 Prach二阶冲突， 当然也可以通过其 他方式来判断二阶 Prach冲突。
由上可见， 在本发明的一些可行的实施方式中， 基站通过 X2接口的 ENB CONFIGURATION UPDATE消息、 X2 SETUP RESPONSE消息及 X2 SETUP REQUEST消息中的任一种传递二阶邻区的 Prach配置信息， 实现了基站实时检 测到网络中发生的二阶邻区 Prach冲突， 不受 OSS网关归属关系制约影响。
本领域普通技术人员可以理解： 实现上述方法实施例的全部或部分步骤可 以通过程序指令相关的硬件来完成， 前述的程序可以存储于一计算机可读取存 储介质中， 该程序在执行时， 执行包括上述方法实施例的步骤， 而前述的存储 介质包括： ROM、 RAM, 磁碟或者光盘等各种可以存储程序代码的介质。 明的精神和范围。 这样， 倘若本发明的这些修改和变型属于本发明权利要求及 其等同技术的范围之内， 则本发明也意图包含这些改动和变型在内。
