Description

一种 WCDMA网络扩容规划的方法和装置
技术领域
本发明涉及无线网络通信规划技术领域, 尤其涉及一种宽带码分多址接 入( WCDMA, Wideband Code Division Multiple Access ) 网络扩容规划的方 法和装置。
背景技术
对于 WCDMA商用网, 随着用户数量及业务量的不断增加,需要根据预 期的容量、 增长需求、 以及现有网络资源的消耗情况, 来决定扩容的方式和 需要增加的设备。 扩容需要监控的资源包括: 功率、 码字、 上行干扰、 信道 处理单元(CE, Channel Element )和传输等,相应的扩容手段包括增加功放、 载频、 CE和传输资源等。
目前的无线网络规划和网络优化, 仅涉及到以下内容:
第一部分内容: 预规划阶段的分期网络规划。 预规划需要根据预测的分 期业务发展, 来做容量估算, 给出所需的资源配置。 预规划结果的准确性依 赖于业务预测和容量估算算法的精度。
第二部分内容: 网络运行阶段的关键性指标 ( KPI , Key Performance Indication )监控。 网络运行时, 监控各个小区的 KPI资源消耗情况, 并设定 相应的门限值, 一旦某小区的资源达到瓶颈, 则准备增加设备进行扩容。
在面对如何在网络运行阶段进行中实现长期的扩容规划这个问题时, 第 一部分的预规划方法, 虽然预规划阶段已经进行了分期规划, 但是其依赖的 业务预测可能与实际的网络发展不符; 同时容量估算方法的输入信息有限, 一般使用上行干扰和下行功率的计算公式来进行评估网络的性能, 输入的信 息包括业务速率、 信噪比、 邻区干扰因子、 下行发射功率、 正交因子、 软切 换因子和业务激活因子等。 其缺陷在于: 上述算法输入参数值大多数只是经 验值, 不一定与实际网络相符; 其次还有很多其他影响网络性能的因素无法 在公式计算中得到体现, 如网络拓朴结构, 外部干扰, 业务分布, 设备性能 的影响等。 因此预规划的结果不一定能直接用来扩容规划。
上述第二部分的 KPI监控方法也不能适用, 因为 KPI监控方法属于网络 运维阶段的实时调整, 需要关注每个小区、 基站的资源消耗情况。 一般需设 置预警门限和扩容门限, 小区的某项资源消耗达到预警门限时, 需要进行密 切关注, 当达到扩容门限时, 则要开始准备扩容。 所以, KPI监控值可以很 好的告诉当前网络的资源利用情况, 给出短期的建议值, 但是显然不能直接 给出长期的扩容规划。 发明内容

下面基于上述第一、 二实施例, 介绍本发明网络扩容规划方法的两个应 用实例:
应用实例 1 :
这里以一个 AMR12.2K业务、 HSDPA业务话务量的增长来预测载频发 送功率利用率的情况为例, 来说明实施的流程, 如图 3所示, 包括如下六个 步骤:
第一步,收集现网数据,作为输入数据。收集的现网数据包括: AMR12.2K 业务话务量、 HSDPA类下行业务话务量、载频发送功率利用率以及小区相关 参数, 小区相关参数为: 密集城区站间距小于 400米的小区、 小区发射功率 20W、 以及 HSPDA与 R99同频。 小区相关参数可根据不同网络的实际情况 进行提取分类, 进而确定不同类型的小区。
在本应用实例中, 收集的现网数据数值如下面表 1所示:
表 1 应用实例 1中收集的现网数据数值
AMR12.2K 业务 HSDPA 业务话务量 小区名字 载频发送功率利用率
话务量 (Erl) (KB) Al 0.30 10.63 77.80
A2 0.39 15.65 109.25
A2 0.41 17.77 249.56
··· ··· ··· ··· 为追求预测的准确性, 原始数据越多越好, 本实施例釆用一个星期的数 据, 时间粒度为 15分钟, 分别取出 AMR12.2K业务话务量、 HSDPA业务话 务量在一个星期中的最大釆样值填入表 1中。
第二步, 基于上述收集到的现网数据进行回归拟合。
其中, 釆用三次线性函数, 以 AMR12.2K业务话务量和 HSDPA业务话 务量为自变量, 载频发送功率利用率为因变量, 进行回归拟合。
y = Kl + K2 xxl + K3 xx^ + K4 xx + K5 xx2 + K6 xx^ + ΚΊ χ χ^ ( 1 ) 这里因变量 y是载频发送功率利用率;
自变量 是 AMR12.2K业务话务量;
自变量 是 HSDPA业务话务量;
Κι~Κ7是校正的系数值。
拟合结果如下:
Figure imgf000011_0001
第三步, 根据第一步的小区相关参数确定小区类型, 将这个拟合结果按 照确定的小区类型保存到关联数据库相应的类别中。
第四步, 根据市场分析得到预期的话务量。
第五步, 将预期的话务量输入关联数据库, 得到预期的资源消耗量。 在本应用实例中, 假设市场分析得到预期话务量为: AMR12.2K业务话 务量增长到现网的 1.5倍, HSDPA业务话务量增加到现网的 3倍, 通过上面 确定的回归拟合函数式( 1 )的计算,得到该小区类型下所有小区的预期资源 消耗量, 即预期的载频发送功率利用率, 如下面表 2所示。 应用实例 1中预期的网络数据数值
Figure imgf000012_0001
需要说明的是, 这个应用实例只是一个简单的举例说明, 在实践中, 可 以用更多的自变量来进行拟合。 如考虑其它业务类型 CS64K 业务、 PS64K 下行业务、 PS128K下行业务、 PS384K下行业务等, 以体现各业务类型对于 载频发送功率利用率的不同需求。
第六步, 根据预期的资源消耗量来制订网络扩容规划策略。
在本应用实例中, 4叚设载频发送功率利用率的扩容门限为 80%, 那么凡 是上面预期载频发送功率利用率消耗在到 80%以上的小区都要考虑进行扩容。 扩容的方式包括增加载波、 增加功放和增加基站等。
应用实例 2:
这里以 AMR12.2K业务、 HSDPA业务话务量来预测 CE的扩容。 流程与 应用实例 1大致相同, 包括以下步骤:
第一步,收集现网数据,作为输入数据。收集的现网数据包括: AMR12.2K 业务话务量、 HSDPA类下行业务话务量、 基站下行 CE利用率以及小区相关 参数, 具体数值小区相关参数与应用实例 1中相同, 故小区的类型也相同。
先基于下面的关系式和所需的转换参数, 计算出基站下行 CE利用率对 应的每小区下行 CE消耗数量:
每小区下行 CE消耗数量=基站下行 CE利用率 X CE配置数量 /小区数; 数值转换过程的数值对应关系如下面表 3所示: 表 3 数值转换过程的数值对应关系
Figure imgf000013_0001
在本应用实例中, 收集的现网数据数值如下面表 4所示:
表 4 应用实例 2中收集的现网数据数值
Figure imgf000013_0002
第二步, 釆取公式(1 ) 的拟合函数对上述的数据进行回归拟合。 其中, 以 AMR12.2K业务话务量和 HSDPA业务话务量为自变量, 载频发送功率利 用率为因变量, 进行回归拟合, 拟合结果如下:
Figure imgf000013_0003
第三步, 根据第一步的小区相关参数确定小区类型, 将这个拟合结果按 照确定的小区类型保存到关联数据库相应的类别中。
第四步, 根据市场分析得到预期的话务量。
第五步, 将预期的话务量输入关联数据库, 得到预期的资源消耗量。 在本应用实例中, 假设市场分析得到预期话务量为: AMR12.2K业务话 务量增长到现网的 1.5倍, HSDPA业务话务量增加到现网的 3倍, 通过上面 确定的回归拟合函数式( 1 )的计算,得到该小区类型下所有小区的预期资源 消耗量, 即预期的下行 CE消耗数量, 如下面表 5所示。
应用实例 2中预期的网络数据数值
Figure imgf000014_0001
第六步, 扩容判断。 本应用实例中, 设置的
CE消耗数量。 各小区的扩容判断结果如下面表 6所示。
表 6 各小区的扩容判断结果
Figure imgf000014_0002
小区 Bl、 B2、 B3的下行 CE消耗数量都小于 CE扩容门限, 因此均无 需扩容。
总之, 本发明实施例是基于当前网络数据进行的扩容规划, 能很好地规 避估算和仿真的准确性低以及工作量大的缺点, 灵活方便地达到对预期资源 的消耗进行判断, 是一种非常适用于工程实践的方法。 通过上述实施方式的说明, 应当可对本发明为达成预定目的所釆取的技 术手段及功效得以更加深入且具体的了解, 然而所附图示仅是提供参考与说 明之用, 并非用来对本发明加以限制。
工业实用 4生
上述技术方案由于是釆用现网数据来确定资源消耗量与业务量的关联关 系, 所以保证了规划方法与现网情况的吻合; 由于不需要输入预规划所需的 网络状态参数,减少了网络扩容规划的工作量;且这种方法的过程简洁有效, 操作简单, 容易实现, 应用面较广。 因此本发明具有很强的工业实用性。
