Abstract: A computer implemented method of operating a base station of a wireless communication network, wherein the method comprises: comparing a number of missing context release messages (108) with a first criterion; comparing the error rate of connection reestablishment messages (112) with a second criterion; executing a cell global identity search algorithm (110) if at least one of the first and the second criterion is fulfilled, wherein the cell global identity of at least one cell with the physical cell identity of the cell where the criterion was fulfilled is requested via an automatic neighbor relation measurement, and wherein a conflict of physical cell identities is detected and reported to an information algorithm (116) when for the physical cell identity at least two cell global identities are found; an information algorithm for informing a central network element (118) and/or at least one base station (120) of the mobile communication network about a conflict of physical cell identities when a conflict of physical cell identities is reported to the information algorithm; and initiating a reassignment of at least one physical cell identity.
Abstract translation: 一种操作无线通信网络的基站的计算机实现的方法，其中所述方法包括：将多个缺失上下文释放消息（108）与第一标准进行比较; 将连接重建消息（112）的错误率与第二准则进行比较; 如果满足第一和第二准则中的至少一个，则执行小区全局身份搜索算法（110），其中通过满足标准的小区的物理小区标识的至少一个小区的小区全局身份被请求 自动相邻关系测量，并且其中当针对物理小区标识找到至少两个小区全局标识时，检测到物理小区标识的冲突并将其报告给信息算法（116） 用于当物理小区标识的冲突被报告给信息算法时，用于向移动通信网络的中央网元（118）和/或至少一个基站（120）通知关于物理小区标识的冲突的信息算法; 以及启动至少一个物理小区身份的重新分配。

Abstract: Embodiments of the claimed subject matter provide a method and apparatus for coordinating concurrent sector optimizations in a wireless communication system. One exemplary embodiment of the method includes determining neighbor relationships between sectors and constructing a precedence graph using the neighbor relationships to link neighboring sectors by a plurality of directed arcs to indicate relative precedence of the neighboring sectors. The exemplary embodiment the method also includes iteratively allocating one or more antenna resources of each of the sectors by selecting a subset of the sectors as master sectors, concurrently optimizing allocation of the antenna resource for each master sector and its associated slave sectors, and reversing precedence indicated by the directed arcs linked to each master sector following optimization of the allocation of the antenna resource(s).
