具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以多种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开。在不冲突的情况下，实施例和实施例中的特征可以相互组合。
在实现本公开的过程中，申请人认为，以一个整体覆盖区来考虑，网络是由不同位置的小区交叠覆盖而形成的连续场。对个别小区的发射功率进行有效的管控，将一小区信号的覆盖强度降低，由邻区接管原小区覆盖的部分覆盖点，则不会影响整个区域的覆盖水平。从系统的工作原理上讲，保证信号的覆盖强度的前提下，小区发射功率越低，系统内干扰就越小，业务质量、用户感知也随之提高。因此，相关技术中提高单个小区的信号强度，信号并不一定会得到增强，还会对除该单个小区之外的小区造成干扰积累，网络指标出现全局性下降。本公开提供了一种小区的参考信道发射功率优化方法及装置，覆盖区按照间隔或者网格划分，进行定点或路线测试，取得覆盖、干扰、切换关系等无线信号数据，建立数据库；输入网络的物理、工程和无线参数，以辅助后续的计算和判决；遍历每个小区对覆盖点的信号强度、邻区关系、和测量报告等信息 进行分析和计算等，判断是否为超期覆盖点，并提取最佳邻区；按照一定的规则，对小区功率进行整定，并多次迭代，以获得较优的覆盖效果。其中，最佳邻区是信号最佳的相邻小区。以下结合附图以及实施例，对本公开进行详细说明。本公开的实施例提供了一种小区的参考信道发射功率优化方法，图1是本公开实施例的小区的参考信道发射功率优化方法的流程图一。
在步骤110中，通过测试获取一定范围内无线信号覆盖区中覆盖点的无线信号数据，并获取覆盖区内每个小区的小区参数信息。
其中，一定范围可以是所关注的整个覆盖区域，如，一定范围可以是所有的小区。
在步骤110中，可以将一定范围内无线信号覆盖区按照间隔或者网格进行划分，对划分后的覆盖区进行定点测试或路线测试，获取覆盖区中覆盖点的无线信号数据。
其中，无线信号数据可以包括：覆盖点的信号强度、覆盖点的小区身份识别号码(Identification，ID)、覆盖点位置、覆盖点的信号质量、以及覆盖点的小区切换关系等。
小区参数信息可以包括：基站位置、基站的参考信道发射功率、基站的业务信道发射功率、基站的扇区朝向、以及基站的高度等基站工程参数和无线参数。
在步骤110中，通过测试获取一定范围内无线信号覆盖区的无线信号数据，并获取覆盖区内每个小区的小区参数信息之后，还可以建立一个数据库，将无线信号数据和小区参数信息保存在数据库中。
在步骤120中，遍历所有小区，根据无线信号数据和小区参数信息确定每个小区的超期覆盖点，并计算每个小区的超期覆盖点的数量之和占本小区覆盖点总数的比例，将所述比例大于预设第一门限的小区，其参考信道发射功率降低预定步长。
图2是本公开实施例的超期覆盖的示意图，图3是本公开实施例的正常覆盖的示意图，如图2和图3所示，在超期覆盖示意图中，小区A中存在部分的超期覆盖点。在正常覆盖的示意图中，小区A中不存在超期覆盖点，其中，超期覆盖点为：小区内距离基站超过一定距离，路损小于预定路损门限，且最佳 邻区在该覆盖点的信号强度大于预定信号强度门限的覆盖点。
在步骤120中，根据测试获取的无线信号数据和小区参数信息确定每个小区的超期覆盖点，可以包括：将基站的业务信道发射功率减去覆盖点的信号强度得到小区每个覆盖点的路损；根据基站位置和覆盖点位置确定小区每个覆盖点距离基站的距离；根据小区每个覆盖点的路损和距离、以及最佳邻区在该覆盖点的信号强度，确定小区每个覆盖点是否为超期覆盖点。
在步骤120中，将小区的参考信道发射功率降低预定步长之后，可以对数据库中参考信道发射功率降低预定步长的小区基站的参考信道发射功率进行更新。
在步骤130中，确定参考信道发射功率降低预订步长的小区中覆盖点的最佳替代小区，并根据最佳替代小区的替代覆盖点的数量确定是否对最佳替代小区设置标记，其中，在后续遍历所有小区过程中不更改已经置标记的小区的参考信道发射功率。
在步骤130中，根据最佳替代小区的替代覆盖点的数量确定是否对最佳替代小区设置标记可以包括：
最佳替代小区的替代覆盖点的数量之和占替代覆盖点所在原小区的覆盖点总数的比例大于预定第二门限；或者，最佳替代小区的替代覆盖点累计数与最佳替代小区的覆盖点总数的比例大于预定第三门限，则对最佳替代小区设置标记。
在步骤130中，确定参考信道发射功率降低预订步长的小区中覆盖点的最佳替代小区之后，可以将数据库中覆盖点所在的原小区的信号强度替换为最佳替代小区的信号强度，以及将数据库中覆盖点所在的原小区的ID替换为所述最佳替代小区的ID。
在步骤140中，遍历每个小区后(对每个小区执行完步骤120和130之后)，确定覆盖区内每个小区的参考信道发射功率。
在执行了步骤140之后，就可以根据每个小区的参考信道发射功率对每个小区的业务信道发射功率进行调整。可选地，还可以根据覆盖点的参考信道接收功率和业务信道的接收功率之间的差值，对业务信道发射功率进行修正。
