Description

一种数据处理方法和无线网络控制器
本申请要求于2016年8月24日提交中国专利局、申请号为CN201610719511.8、发明名称为“一种数据处理方法和无线网络控制器”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信领域，尤其涉及一种数据处理方法和无线网络控制器。
背景技术
随着通信技术的发展，一个基站可以引入的小区越来越多。若一个无线网络控制器RNC服务的区域中的大量基站引入了多个小区，则RNC会将频点接近或者地理位置接近的两个小区配置成同频邻区的关系。若大量同频邻区过于密集，则可能会导致小区之间的导频污染，使得软切换区域增大，不必要的软切换的次数增加，从而导致这一片区域的掉话率升高。
当终端需要切换小区时，RNC可以向终端下发一个同频测量控制的信令，该同频测量控制包含多个同频邻区，以使得终端对该多个同频邻区进行信号质量测试，以便选择信号质量良好的同频邻区进行切换。为了保证终端的正常切换，当下的通信协议规定，同频测量控制里面最多可以包含31个同频邻区。然而，若在同一段时间内，过多终端接收的同频测试控制包含的同频邻区的个数达到或者接近31，则会容易引起掉话，且会消耗过多的时间进行下发，从而影响业务建立的时延。数据显示，同频邻区的个数达到或者超过31的小区比例相当大。
为此，存在一些网规网优工具，可以为一个小区的同频邻区的重要程度进行排序，然后取一部分作为重要同频邻区，当RNC下发同频测量控制的信令时，该信令仅携带重要同频邻区，而不携带非重要同频邻区，以使得RNC下发的同频测量控制的信令携带的同频邻区的个数达到或者超过31的比例下降，从而改善容易引起掉话的情况，且会避免消耗过多的时间进行下发，从而降低业务建立的时延。其具体运作流程为：1、从RNC中导出相关数据和参数；2、将该相关数据和参数导入到网规网优工具中，进行该小区的同频邻区的重要程度进行排序；3、工具会根据排序结果，得到一个小区的重要同频邻区。
然而，由于是通过从RNC中导出相关数据和参数，并将该相关数据和参数导入到网规网优工具中，因此当确定一个小区的重要同频邻区时，相对麻烦，不够智能。
发明内容
本发明实施例提供了一种数据处理方法和无线网络控制，用于确定重要同频邻区，以使得终端仅对重要同频邻区进行信号质量测试。
有鉴于此，本发明实施例第一方面提供了一种数据处理方法，包括：

由于通过一系列的操作，使得得到的重要同频邻区集合更加符合相应的需求，而且为如何使用切换相关数据提供一种具体可以操作的方法。
结合第一方面、第一方面的第一种实施方式，第一方面的第三种实施方式，包括：
优选的，可以确定非重要同频邻区，该非重要同频邻区集合为该同频邻区集合中除该重要同频邻区集合以外的同频邻区，将非重要同频邻区集合从检测集加入活动集。
由于将非重要同频邻区加入活动集，因而当终端对重要同频邻区的切换都失败的时候，可以考虑选择非重要同频邻区，使得更不容易掉话。
本发明实施例第二方面提供了一种无线网络控制器，包括：
配置模块，用于配置一个小区的同频邻区，得到该小区的同频邻区集合；确定模块，用于从该同频邻区集合中确定重要同频邻区，得到重要同频邻区集合；发送模块，用于当检测到该小区的终端切换至新小区时，通过向该终端发送同频测量控制信令，该同频邻区测量控制信令仅携带重要同频邻区集合，而不携带非重要同频邻区集合，使得该终端对该重要同频邻区集合进行信号质量测试
由于可以由无线网络控制器自动实现区分重要同频邻区和非重要同频邻区，而不需要借助第三方网规网优工具，体现了智能化以及便利性。
结合第二方面，第二方面的第一种实施方式，包括：
获取子模块，用于通过获取该小区的切换相关数据，然后根据该切换相关数据从该同频邻区集合中确定重要同频邻区，得到该重要同频邻区集合，需要说明的是，该切换相关数据可以包括切换尝试次数和切换成功次数。
由于通过该小区的切换相关数据确定重要同频邻区集合，因此可以实时获取数据，更便捷以及不会造成时延。

由于通过一系列的操作，使得得到的重要同频邻区集合更加符合相应的需求，而且为如何使用切换相关数据提供一种具体可以操作的方法。
结合第二方面、第二方面的第一种实施方式，第二方面的第三种实施方式，包括：
加入模块，可以用于确定非重要同频邻区，该非重要同频邻区集合为该同频邻区集合中除该重要同频邻区集合以外的同频邻区，将非重要同频邻区集合从检测集加入活动集。
由于将非重要同频邻区加入活动集，因而当终端对重要同频邻区的切换都失败的时候，可以考虑选择非重要同频邻区，使得更不容易掉话。
本发明实施例第三方面提供了一种无线网络控制器，包括：
收发器、存储器、处理器以及总线；该收发器、该存储器以及该处理器通过该总线连接；该处理器，用于配置小区之间的同频邻区关系，得到一个小区的同频邻区集合，确定该同频邻区集合中的重要同频邻区，得到重要同频邻区集合；该收发器，用于当检测到该小区的终端切换至新小区时，向该终端发送同频测量控制信令，使得该终端对该重要同频邻区集合进行信号质量测试，而不对非重要同频邻区集合进行信号质量测试；该存储器，用于存储程序、该处理器配置的该同频邻区集合、该处理器确定的该重要同频邻区集合、该收发器发送的该同频测量控制信令。

具体实施方式
本发明实施例提供了一种数据处理方法和无线网络控制，用于确定重要同频邻区，以使得终端仅对重要同频邻区进行信号质量测试。
为了使本技术领域的人员更好地理解本发明实施例方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
如图1所示，是一种数据处理系统的示意图，该数据处理系统包括无线网络控制器、多个基站和多个终端。
在本发明实施例中，无线网络控制器(英文：Radio Network Controller；缩写：RNC)是第三代无线网络中的主要网元，是接入网络的组成部分，负责移动性管理、呼叫处理、链路管理和移交机制等功能。
在本发明实施例中，该RNC负责收集终端上报的切换相关数据，并且把切换相关数据进行汇总和计算，得到重要同频邻区集合，然后给终端下发的同频测量控制里面只携带重要同频邻区集合中的同频邻区，而不携带非重要同频邻区。
RNC和基站组成了第三代移动通信(缩写：3G)网络中的通用地面无线接入网(英文：Universal Terrestrial Radio Access Network；缩写：UTRAN)，所以RNC是UTRAN的交换和控制网元。作为3G网络的一个关键网元，RNC主要用于管理和控制多个基站。需要说明的是，RNC的整个功能分为两部分：无线资源管理功能和控制功能。无线资源管理主要用于保持无线传播的稳定性和无线连接的服务质量；控制功能包含了所有和无线承载建立、保持和释放相关的功能。
在本发明实施例中，基站即公用移动通信基站，是指在一定的无线电覆盖区中，通过移动通信交换中心，与移动电话终端之间进行信息传递的无线电收发信电台。在本发明实施例中，基站的结构可以包括基带处理单元(英文：Building Base band Unit；缩写：BBU)和射频拉远单元(英文：Radio Remote Unit；缩写：RRU)，RRU和天馈系统(天线)。
在一些可行的实施例中，除上述对于RNC和基站的描述外，还可以以其它更为概括的结构来展示RNC和基站。对于RNC，可主要体现处理器/处理电路，存储器，以及接口(包括与核心网设备连接的接口，与基站连接的接口)。对于基站，可以体现处理器/处理电路、存储器，以及收发器等，此处不作限定。
在本发明实施例中，终端可以包括总线、处理器、存储器、输入输出接口、显示设备和通信接口。总线是连接所描述的元素的电路并且在这些元素之间实现传输。例如，处理器通过总线从其它元素接收到命令，解密接收到的命令，根据解密的命令执行计算或数据 处理。
在本发明实施例中，“多扇区”解决方案即可以应用于UMTS，也可以应用于长期演进(英文：Long Term Evolution；缩写：LTE)和全球移动通信系统(英文：Global System for Mobile Communication；缩写：GSM)，此处不作限定。
随着移动宽带的快速发展和用户的增加，运营商在网络容量方面面临巨大挑战，特别是在高话务城区热点，流量需求被严重压抑，用户体验难以保障。受限于新站址获取困难、频谱资源有限等因素，运营商难以通过增加站点或增加频谱扩充载波等传统方式提升网络容量。
针对这些挑战，“多扇区”解决方案解决高话务城区热点容量不足问题，以高效保障用户体验。在蜂窝通信网中，一个基站可以分为三个小区，称为“三扇区”解决方案。基站可设在小区的中心，用全向天线形成圆形的覆盖区，这就是“中心激励”方式。也可将基站设在每个小区六边形的三个顶点上，每个基站采用三副120度扇形辐射的定向天线，分别覆盖三个相邻小区的各三分之一的区域，每个小区由三副120度扇形天线共同覆盖，这就是“顶点激励”方式，而每副天线覆盖的区域就是一个基站扇区，一个基站扇区也称为一个小区。
一个基站也可以分为六个扇区或者九个扇区，被称为“六扇区”解决方案或者“九扇区”解决方案。其中，“九扇区”解决方案运用空间复用技术及华为独特算法，通过自行研发的三波束高增益劈裂天线，在水平方向上将一个120度的扇区劈裂为三个40度的扇区，即现在使用三个扇区对原来使用一个扇区的同一片区域进行覆盖，实现网络容量提升到原有“三扇区”的2.2～2.7倍，覆盖提升2～3dB。“九扇区”解决方案在不增加站点和频谱资源的情况下，提升网络容量为原有三扇区的2.5倍，有效保障高话务城区热点的用户体验。
“九扇区”解决方案的推出，帮助更多运营商最大化利用现有网络频谱资源，有效解决容量问题，建设更有竞争力的高质量用户体验网络。“九扇区”解决方案是“多扇区”解决方案的重要组成部分。截止目前，“六扇区”解决方案已在全球70多张网络部署，“九扇区”解决方案部署逐渐拉开帷幕。未来多扇区解决方案将持续创新，助力运营商提升网络容量，满足未来不断增长的用户数及数据业务需求。
在移动通信系统中，为了提高频率利用率，增加系统的容量，常常采用频率复用技术。频率复用是指在相隔一定距离后，在给定的覆盖区域内，存在着许多使用同一组频率的小区，这些小区称为同频小区。同频小区之间的干扰称为同频干扰。
一般采用频率复用的技术以增加频谱效率。当小区不断分裂使基站服务区不断缩小，同频复用系数增加时，大量的同频干扰将取代人为噪声和其它干扰，成为对小区制的主要约束。这时移动无线电环境将由噪声受限环境变为干扰受限环境。
在本发明实施例中，当终端需要进行切换小区时，需要确定切换至哪个同频邻区，则需要对同频邻区进行信号质量测试。在一些可行的实施例中，当基站发现终端需要切换小区时，会下发一个同频测量控制信令，该同频测量信令里携带该小区的多个同频邻区，以使得终端对该小区的多个同频测量邻区进行信号质量测试，以选择信号质量较好的同频邻区进行切换。
然而，协议331里规定，为了保证终端的正常的切换，同频测量控制里面最多可以携 带31个邻区全部进行下发测量。但是同频测量控制过大的话，会容易引起信令无线承载(英文：Signalling Radio Bearer；缩写：SRB)复位的掉话，同时也会由于消耗过多的时间进行下发，影响业务的建立的时延。
根据数据统计，菲律宾Globe局点：6个RNC的统计结果，38％的同频邻区个数超过30；泰国AIS局点：50％的邻区个数超过31；澳洲VHA局点：14％的邻区个数超过31，58％的邻区个数在20-30之间。
随着多扇区的发展，引入的小区个数增多，同频邻区个数超过31的比例增长，小区间的导频污染，软切换区域增加，不必要的软切换增加，导致掉话率升高。
本发明实施例通过提出了通过配置小区的同频邻区，得到同频邻区集合后，可以确定该同频邻区集合中的重要同频邻区，得到重要同频邻区集合，当检测到该小区的终端切换至新小区时，可以向该终端发送同频测量控制信令，而不需要手动操作，而是由无线网络控制器自动实现，体现了智能化以及便利性。
为便于理解，下面对本发明实施例中的具体流程进行描述，请参阅图2，本发明实施例中一种数据处理方法一个实施例包括：
201、配置小区的同频邻区，得到该小区的同频邻区集合。
在本发明实施例中，RNC可以对小区之间是否同频邻区关系进行配置。需要说明的是，同频邻区关系一般都是根据两个小区的之间的地理位置的远近决定的，如果两个小区的地理位置比较接近，覆盖范围有交叠，一般就会配置成邻区关系，反之，就不配置。
在一些可行的实施例中，一般是会根据终端上报的测量到小区的信号，有源小区的和其他小区的关系的信号，如果有些小区的信号比较强，一般就会将该小区和源小区配置成同频邻区关系。然而，在另一些可行的实施例中，当周围的无线环境发生改变的话，如新增或删除了一个基站，或者新建了一栋楼等等，同频邻区关系就可能发生一些变化。然而若没有这些无线环境的改进，则同频邻区关系一般就不会发送改变。
例如，若基站A的小区A1和基站B的小区B1的之间的间隔比较接近，信号比较强，则会将小区A1和小区B1配置成邻区关系。同样的，如果基站A的小区A1和基站A的小区A2也是同样的原则，一般一个基站下面的同一个频点的不同小区都是会配置成邻区关系的。当为所有小区配置了相应的同频邻区的关系后，每个小区都有相应的同频邻区集合。需要说明的是，一个小区没有任何一个同频邻区，即该同频邻区集合可以为空集。
202、获取该小区的切换相关数据。
在一些可行的实施例中，由于一个基站下的小区越来越多，一个小区的同频邻区也越来越多，当需要下发同频测量控制时，大量的同频测量控制都携带上限31个同频邻区。为此，则需要减少其中连接的概率较小的同频邻区，留下重要同频邻区。为了区分重要同频邻区和非重要同频邻区，则需要小区的切换相关数据。
在一些可行的实施例中，终端每次尝试进行切换小区，都会记录下来，然后定时或者事件触发时发送到RNC，终端可以只发送尝试次数和成功次数，也可以计算得到成功率之后发送，此处不作限定。终端可以接收来自终端发送至基站，然后通过基站发送的关于小区的切换相关数据。在一些可行的实施例中，该切换相关数据包括切换尝试次数和切换成 功次数，在另一些可行的实施例中，还可以包括切换成功率，此处不作限定。
203、根据该切换相关数据计算该同频邻区集合中各个同频邻区的重要程度排名，得到同频邻区重要程度排名表。
在一些可行的实施例中，可以通过成功次数以及尝试次数的切换相关数据对同频邻区集合中的同频邻区进行评分，根据评分进行排名，得到同频邻区重要程度排名表。
在一些可行的实施例中，可以通过统计源小区到配置中切换至不同的同频邻区的切换成功次数以及对应的切换尝试次数，通过切换成功次数/切换尝试次数计算得到同频切换成功率。
在一些可行的实施例中，可以使得同频邻区分值等于：切换成功率*切换成功次数。可以理解的是，切换成功率是表示其重要程度的重要参考标准，但是不是唯一的标准，因为如果实施的方案的次数非常少，如1次，则即使成功率是100％，也不能称之为是重要的同频邻区。
在一些可行的实施例中，为了更好地对分值进行比较，可以将其分值归化为0-100之间的数值。具体方法可以为将各个同频邻区的分值除以分值最大的同频邻区的分值，再乘以100，得到0-100之间的数值。需要说明的是，如果切换尝试次数为0的，直接切换部分得分为0，不用计算切换成功率。
需要说明的是，原来的技术下是通过人手使用网规网优工具从RNC中获取切换相关数据，经过汇总、分析和计算得出每个同频邻区的分数，再根据进行重要程度的排名。而在本发明实施例中，仅依靠RNC自动使用汇总、分析和计算切换相关数据得到得出每个同频邻区的分数，再根据进行重要程度的排名。
204、根据该切换相关数据确定该重要同频邻区集合中同频邻区的个数，得到该重要同频邻区个数。
在一些可行的实施例中，当得到不同的同频邻区的重要程度排名之后，可以取其中若干个同频邻区作为重要同频邻区。然而，在如果仅取其中固定个数的同频邻区作为重要同频邻区，则有可能产生某些分值很低的也可能是重要同频邻区，分值很高的却不是重要同频邻区。所谓重要同频邻区，即其被切换的次数足够多，同时成功率足够高，为此，本发明实施例中提供一种可以确定其重要同频邻区集合中同频邻区的个数的方法。
具体为，首先设置最小同频邻区个数门限对应的邻区排名M。如一般M可以设置为7个或者8个，此处不作限定。根据最小同频邻区个数门限，邻区按照切换成功次数的排序从高到低，取排名前1-M的同频邻区。
然后获取累积分布函数(英文：Cumulative Distribution Function；缩写：CDF)切换占比门限对应的邻区排名N。CDF为随机变量小于等于某个数值的概率，此处CDF切换占比指邻区排名≤N的两两小区软切换成功次数占源小区总软切换累积成功数的比例。CDF切换占比门限对应的邻区排名N的取值办法：大于等于该门限对应的邻区统计排名的第一个。例如，若CDF切换占比门限设置为90％，则如下表格小区标识为18431的小区对应的切换占比90％邻区是排名11的同频邻区，即N＝11。需要说明的是，其CDF切换占比门限可以根据需要进行设备，如80％，70％，以适应网络的需求，此处不作限定。
按照切换成功次数由高到低统计CDF切换占比，得到结果类似下面的表格：
小区 同频邻区 切换成功次数 累计成功次数 邻区排名 CDF
18431 18433 752 752 1 0.246962
18431 28331 440 1192 2 0.391461
18431 18432 417 1609 3 0.528407
…… …… …… …… …… ……
18431 47282 127 2649 10 0.869951
18431 35343 122 2771 11 0.910016
18431 28247 121 2892 12 0.949754
…… …… …… …… …… ……
18431 28243 3 3042 21 0.999015
18431 28083 2 3044 22 0.999672
18431 47272 1 3045 23 1
接着，区分重要邻区和非重要邻区，按照邻区排名，取MIN{配置的同频邻区个数，MAX(M，N)}数量的同频邻区为重要同频邻区的数量，在该数量的排名以及之前的都是重要同频邻区，其他的为非重要邻区，以此得到重要同频邻区集合和非重要同频邻区集合。需要说明的是，之所以取MIN{配置的同频邻区个数，MAX(M，N)}，是因为配置的重要同频邻区的个数不可能超过配置的同频邻区个数。获取同频的重要邻区后，同频测量控制优化的下发邻区就是下发重要的邻区关系。需要说明的是，以上是一个较为理想的得到重要同频邻区的计算方式，还可以有其他计算方式，此处不作限定。
205、根据该同频邻区重要程度排名表和该重要同频邻区个数确定重要同频邻区，得到该重要同频邻区集合。
在一些可行的实施例中，可以根据以上的同频邻区重要程度排名表以及该重要同频邻区个数确定重要同频邻区，以得到重要同频邻区集合。具体的为，优选的，取同频邻区重要程度排名表中前重要同频邻区个数的同频邻区作为重要同频邻区。
需要说明的是，同频邻区重要程度排名表以及该重要同频邻区个数可以按照以上方式计算得到，也可以通过其他方式计算得到，如同频邻区重要程度排名表仅根据成功率排名，或者仅根据切换尝试次数到达预置个数并成功率到达预置数值的作为重要同频邻区，而该重要同频邻区个数可以通过人为设置为10或者20，此处不作限定。
206、当检测到该小区的终端切换至新小区时，向该终端发送同频测量控制信令，该同频测量控制信令用于指示该终端对该重要同频邻区集合进行信号质量测试。
在一些可行的实施例中，当终端需要切换的时候，或者其他需要进行同频测量的时候，可以请求RNC发送同频测量控制信令。在本发明实施例中，RNC下发的同频测量控制信令里仅携带重要同频邻区集合，不携带非重要同频邻区集合。当终端接收到同频测量控制信令时，即可对重要同频邻区进行信号质量测试，选择其中信号质量较好的进行切换。
207、将非重要同频邻区集合加入活动集，该非重要同频邻区集合为该同频邻区集合中除该重要同频邻区集合以外的同频邻区。
在本发明实施例中，同频邻区集合中除了重要同频邻区之外的同频邻区均被称为非重要同频邻区。在一些情境下，及时是重要同频邻区，仍然有可能会有掉话风险，则非重要同频邻区即使没有进行信号质量测试，仍然可以对其进行激活，使得其进入活动集，当重要同频邻区都不可进入时，则可以选择非重要同频邻区，降低掉话率。
上面对本发明实施例中一种数据处理方法进行描述，下面对本发明实施例中的无线网络控制器进行描述。
请参考图3，本发明实施例还提供一种无线网络控制器300，该无线网络控制器300包括：
配置模块301，用于配置小区的同频邻区，得到该小区的同频邻区集合。
