Description

通信业务质量的统计方法及其系统和终端
技术领域
本发明涉及移动通信领域，特别涉及网络优化技术。
背景技术
近年来随着移动通信的飞速发展，网络规模不断扩大用户数量急速上升，用户对网络性能质量的要求也不断提高，运行商对网络的管理也从对信号覆盖的定性要求转变为对网络性能指标的定量管理。
移动无线网络运行状况动态变化较大，受外界客观环境影响因素较多。用户市场不断扩大，网络不停扩容，网络服务项目的不断增加，城乡建筑的日新月异，使得话务量分布动态变化。因此，网络优化是移动通信网络运行维护工作中的一个重要组成部分，其目的就是提高网络通信质量，改善服务形象，充分挖掘网络资源，使投资得到应有回报。
随着新技术的发展，码分多址(Code Division Multiple Access，简称“CDMA”)/全球移动通信系统(Global System for mobile Communication，简称“GSM”)网络上开通的业务种类越来越多，不仅包括话音服务，还将会开通无线数据、图像等增值服务项目，向多媒体方向发展。这样，网络的维护质量要求也就越来越高，网络优化的任务越来越重。网络优化是在充分了解网络运行状态的前提下，通过各种技术手段，对网络中不合理的部分进行必要的调整，使网络达到最优运行状态的过程，网络优化的效果直接决定了用户能否获得期望的服务。
网络优化工作就是在不断监视网络的各项技术数据中，根据发现的问题，通过对设备、参数的调整，使网络的性能指标达到最佳状态，最大限度地发挥网络能力，提高网络的平均服务质量。
网络优化工作的内容包含以下几方面：设备排障；提高网络运行指标：无线接通率、话务掉话比、掉话率、最坏小区、切换成功率、阻塞率等；提高话音质量；网内各小区之间话务均衡；网络均衡：信令负荷均衡、设备负荷均衡、链路负荷均衡等；合理调整网络资源：提高设备利用率、提高频谱利用率、每信道话务量等；建立和维护长期的网络优化工作平台，建立和维护网络优化档案等。
传统的网络优化手段基于样本的影响网络性能以及用户通信质量的关键性能指标(Key Parameters Indication，简称“KPI”)分析，使用专用测试设备进行室内/室外业务测试，如测试手机、扫频仪、频谱仪、全球定位系统(Global Position System，简称“GPS”)、组成的路测系统等，选择测试路线，反复进行业务测试获取测试样本。但是，通过这种方法所获得的数据只是少量样本数据，且对样本数据进行的分析局限于“硬指标”，比如小区导频、接收机功率、接口间信令、信道误码率、误帧率、吞吐率等，虽然随着工具的发展和工程师对网络运行规律的掌握，这种“硬指标”分析结果可以比较接近实际情况，但其准确性和可信度仍然不高。另外，人的实际感受是无法通过工具重现、描述的，对实际的网络运行维护来说，满足用户要求、使用户在接收服务中获得好的感受是最终的目标，传统的优化工具更专注于网络本身的健康。有这样的假设：如果网络健康，那么用户会得到理想的服务，这样的假设过于理想，而且不同的设备商对“健康”会产生不同的理解。
最新的网络优化手段是通过评判语音、图像质量的专用工具，对标准样本经过网络传输后的畸变样本的分析，评判端到端的网络质量。比如说，利用语音、图像质量评估算法/软件，把端到端之间的网络视为黑盒子，输入一个标准样本，得到输出样本，使用算法评估两者之间的差异，进而判断该差异是否超过一个容限，反映实际网络质量低于某个水平。但是，这种方法仍然是基于有限样本的测试，测试环境无法模拟实际的环境，而且，无法帮助定位网络问题，仅能提供有关质量“好”或“不好”的信息。
发明内容
有鉴于此，本发明的主要目的在于提供一种通信业务质量的统计方法及其系统和终端，使得运营商可以得到大量统计样本，从而掌握网络实际服务质量以便进行网络优化。
为实现上述目的，本发明提供了一种移动网络中通信业务质量的统计方法，包含以下步骤：
移动终端根据用户的输入生成对通信质量的评价数据，并将该评价数据发送到网络侧，所述评价数据中包含业务类型，和与相应业务相关的各关键能力指标项，每个关键能力指标项分为不同等级，分别表示用户对通信质量的不同评价，其中，根据业务类型决定与该业务相关的关键能力指标项的项数，所述评价数据通过短消息、多媒体消息、无线应用协议或通用分组无线业务方式发送到网络侧；
所述网络侧对来自所述移动终端的所述评价数据进行统计，得到通信业务质量统计结果。
其中，所述评价数据中包含移动终端所在的小区标识；
所述网络侧对来自移动终端的所述评价数据进行统计的步骤包含以下子步骤：
所述网络侧根据所述评价数据中的小区标识，对来自不同小区的评价数据进行统计，得到各小区的通信业务质量统计结果。
此外在所述方法中，所述网络侧对来自移动终端的所述评价数据进行统计的步骤包含以下子步骤：
所述网络侧根据所述移动终端的号码在归属签约用户服务器中查找该移动终端所对应的用户类别，对不同用户类别的评价数据进行统计，得到各用户类别的通信业务质量统计结果。
此外在所述方法中，所述网络侧对来自移动终端的所述评价数据进行统计的步骤包含以下子步骤：
所述网络侧根据所述评价数据中的业务类型，对不同业务类型的评价数据进行统计，得到各类业务的通信质量统计结果。
此外在所述方法中，所述关键能力指标项包含以下之一或其任意组合：
通话有无接通、呼叫接通时间、通话过程中是否存在异常中断、语音清晰度、图像清晰度、以及图像流畅度。
此外在所述方法中，所述网络侧通过向所述移动终端发送短消息通知该移动终端开启或关闭生成和上报所述评价数据的功能。
本发明还提供了一种移动网络中通信业务质量的统计系统，包含网络侧与至少一个移动终端，所述移动终端内还包含用于接收用户输入信息的模块，和用于根据用户的输入生成对通信质量的评价数据，并将该评价数据发送到网络侧的模块，所述评价数据中包含业务类型，和与相应业务相关的各关键能力指标项，每个关键能力指标项分为不同等级，分别表示用户对通信质量的不同评价，根据业务类型决定与该业务相关的关键能力指标项的项数，所述评价数据通过短消息、多媒体消息、无线应用协议或通用分组无线业务方式发送到网络侧；
所述网络侧内还包含用于对来自所述移动终端的所述评价数据进行统计并得到通信业务质量统计结果的模块。
本发明还提供了一种移动终端，包含用于接收用户输入信息的模块，和用于根据用户的输入生成对通信质量的评价数据，并将该评价数据发送到网络侧的模块，供网络侧对通信业务质量进行统计。其中，所述评价数据中包含业务类型，和与相应业务相关的各关键能力指标项，每个关键能力指标项分为不同等级，分别表示用户对通信质量的不同评价，根据业务类型决定与该业务相关的关键能力指标项的项数，所述评价数据通过短消息、多媒体消息、无线应用协议或通用分组无线业务方式发送到网络侧。
通过比较可以发现，本发明的技术方案与现有技术的主要区别在于，由移动终端根据用户的输入生成对通信质量的评价数据，并将该评价数据发送给网络侧，网络侧对来自移动终端的评价数据进行统计，从而得到通信业务质量统计结果。由于发送给网络侧的评价数据是从用户对某项业务的实际感受转化而成的各种指标，因此，网络侧可以获得大量来自真实用户的样本，从而掌握网络实际服务质量，指导或验证网络的优化工作。如果网络侧经过统计判定某区域某业务异常，则可利用传统路测手段进行问题排查，进而有效提高网优效率并减少用户投诉。
网络侧可通过多种方式对来自移动终端的用户对通信质量的评价数据进行统计，比如说，对不同小区的业务质量进行统计，从而得到小区的通信业务质量的分布情况；或者，对不同用户类别的业务质量进行统计，得到各用户类别的通信业务质量统计结果，从而可以获知特定类型的用户对某项业务的感受，如VIP用户浏览网页的感受；也可以对不同业务的质量进行统计，得到各业务的通信质量统计结果。
通过与业务相关的各项KPI表示该业务的通信质量，每项KPI进一步分为不同等级，分别表示用户对通信质量的不同评价，清楚有效地表达了用户对某项业务的各项KPI的感受，且由于以较小的数据量表达了用户对通信质量的评价，使得该评价数据的发送不会为网络增加过多的负担。

图3是根据本发明第三实施方式的通信业务质量的统计方法流程图。
具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述。
本发明的核心在于，移动终端将用户对业务的实际感受转化为对通信质量的评价数据，并将该评价数据发送给网络侧，网络侧可根据该评价数据统计不同小区的业务质量、不同用户类别的业务质量、以及不同类型业务的质量等。
以上对本发明的原理做了简单说明，下面根据该原理，对本发明的第一实施方式通信业务质量的统计方法进行详细阐述。
如图1所示，在步骤110中，移动终端判断生成和上报评价数据的功能是否打开。具体地说，在移动终端中预置有根据用户的输入生成对通信质量的评价数据的软件，该软件的开启与关闭由网络侧进行控制。比如说，网络侧下发表示开启该软件的特定短消息，收到该短消息的移动终端则打开生成和上报评价数据的功能。如果网络侧下发表示关闭该软件的特定短消息，则收到该短消息的移动终端禁止生成和上报评价数据的功能。在本步骤中，移动终端判断该生成和上报评价数据的功能是否打开，如果是，则进入步骤120，否则，结束本流程。
在步骤120中，移动终端根据用户的输入生成对通信质量的评价数据。具体地说，移动终端通过若干个KPI项来表示相应的某项业务的通信质量，每一项KPI进一步分为不同等级，不同等级对应用户的不同感受。并提示用户对各KPI项的等级值进行选择，根据用户的输入生成对通信质量的评价数据，将用户对通信质量的实际感受转化为可统计的评价数据。对每一种具体的业务，都需设置相应的若干个可影响用户使用感受的KPI项，用对各KPI项进行分级的方法代表用户的实际感受。
比如说，对于网络商提供的可视电话这项业务而言，从拨号到结束通话，其中可以影响用户使用感受的因素包括通话连接的成功率、等待接通的时间、是否会掉话、语音清晰度、和图像清晰度等等，因此，可设置以下几个KPI项：
(1)通话有无接通。如果通过没有接通被叫，那么本次业务是失败的，该指标了反映终端业务建立请求的成功率。
(2)呼叫接通时间。如果经过很长时间用户才听到对方振铃，用户也会对这种等待感到不满，该指标反映了呼叫接续中的时延。
(3)通话过程中是否存在异常中断。该指标对应于业务掉话。
(4)语音清晰度。频繁的杂音、断续也会降低用户的满意度，这个指标对应于网络无线链路的误码率、误帧率。
(5)图像清晰度。严重的马赛克意味着终端解调的数据出现了严重的错误，会严重影响到用户的业务体验，该指标反映了用户在画面上的满意程度。
(6)图像流畅度。频繁的停顿、跳帧也意味着空口解调性能的恶化。
每一个KPI项都分为“A”、“B”、“C”、“D”四个等级，分别代表“好”、“较好”、“一般”、“差”四种不同的感受。移动终端根据用户针对每一项KPI输入的“A”、“B”、“C”、或“D”，生成能够表示用户对通信质量的主观评价的表单，在该表单中还可包含如小区标识、业务类型等其他的一些信息，如表1所示。
 
字段名称 长度(字节)
业务质量反馈标识 1
小区标识 4
 
业务类型 1
KPI量化值 1*n
表1
其中，以不同的特定值表示不同的业务类型。比如说，将业务类型字段设置为1时，表示该业务为自适应多速率(Adaptive Multi-Rate，简称“AMR”)语音；将该字段设置为2时，表示该业务为可视电话；将该字段设置为3时，表示该业务为网页浏览；将该字段设置为4时，表示该业务为流业务；将该字段设置为5时，表示该业务为短消息业务、彩信业务、或电子邮件业务。以诸如此类的方式，为不同的业务设置相应的业务类型值。
KPI量化值字段的长度为1*n，其中，n取决于业务类型，表示为该业务类型所设置的KPI项数，也就是说，如果业务类型为可视电话，并且为该可视电话业务设置了6个KPI项，那么，n即为6，KPI量化值字段的长度为6个字节，对于每个KPI项，用一个字节表示该KPI的等级。
接着，进入步骤130，移动终端将生成的评价数据发送给网络侧。针对上述案例，移动终端将根据用户的输入所生成的表单以短消息的形式发送给网络侧。由于在该表单中，仅通过1*n个字节就清楚有效地表达了用户对该项业务的感受，因此该表单的发送不会为网络增加过多的负担。可以理解，除了短消息以外，表单也可以通过其它方式传送到网络侧，例如可以通过多媒体消息(Multimedia Message)，无线应用协议(Wireless ApplicationProtocol，简称“WAP”)，通用分组无线业务(General Packet Radio Service，简称“GPRS”)等方式上传。
接着，进入步骤140，网络侧统计不同小区的业务通信质量。针对上述案例，网络侧根据收到的表单中的小区标识，对来自不同小区的表单进行统计，得到各小区的通信业务质量统计结果，从而获取小区的通信业务质量的分布情况。比如说，预定义一个门限，如果小区的通信业务质量超过该门限，则表示该小区的通信质量较好，否则，说明该小区的通信质量有待改进。根据各小区的通信业务质量统计结果，将低于该门限的小区在地图中标识出来，从而可清楚地获得小区的通信业务质量的分布情况。
由于网络侧是根据大量的来自移动终端的评价数据对通信业务质量进行统计，因此所得出的统计结果具有较高的准确性和可信度，从而掌握网络实际服务质量，指导/验证网络优化。而且，由于评价数据是根据用户的输入所生成的，因此能够直接体现出用户的实际感受，因此可根据用户的需求进行网络优化，使用户在接收服务中获得最好的感受，从这种统计结果出发的网优方法可以达到节约时间、降低费用、以及提高效率等目的。
本发明的第二实施方式通信业务质量的统计方法如图2所示，在步骤210中，移动终端判断生成和上报评价数据的功能是否打开，如果是，则进入步骤220，否则，结束本流程。本步骤与步骤110完全相同。
在步骤220中，移动终端根据用户的输入生成对通信质量的评价数据。本步骤与步骤120完全相同。
接着，进入步骤230，移动终端将生成的评价数据发送给网络侧。本步骤与步骤130完全相同。
接着，进入步骤240，网络侧统计不同用户类别的业务通信质量。具体地说，网络侧根据移动终端的号码在归属签约用户服务器(Home SubscriberServer，简称“HSS”)中查找该移动终端所对应的用户类别，对不同用户类别的评价数据进行统计，得到各用户类别的通信业务质量统计结果，从而可以获知特定类型的用户对某项业务的感受，如VIP用户浏览网页的感受。
不难发现，本实施方式与第一实施方式大致相同，其区别仅在于，在第一实施方式中，网络侧根据评价数据中的小区标识，对来自不同小区的评价数据进行统计。而在本实施方式中，网络侧根据移动终端的号码在HSS中查找该移动终端所对应的用户类别，对不同用户类别的评价数据进行统计。
本发明的第三实施方式通信业务质量的统计方法如图3所示，在步骤310中，移动终端判断生成和上报评价数据的功能是否打开，如果是，则进入步骤320，否则，结束本流程。本步骤与步骤110完全相同。
在步骤320中，移动终端根据用户的输入生成对通信质量的评价数据。本步骤与步骤120完全相同。
接着，进入步骤330，移动终端将生成的评价数据发送给网络侧。本步骤与步骤130完全相同。
接着，进入步骤340，网络侧统计不同类型业务的通信质量。具体地说，网络侧根据评价数据中的业务类型，对不同业务类型的评价数据进行统计，得到各类业务的通信质量统计结果。
不难发现，本实施方式与第一实施方式大致相同，其区别仅在于，在第一实施方式中，网络侧根据评价数据中的小区标识，对来自不同小区的评价数据进行统计。而在本实施方式中，网络侧根据评价数据中的业务类型，对不同业务类型的评价数据进行统计。
本发明的第四实施方式通信业务质量的统计系统包含网络侧与至少一个移动终端，在移动终端内还包含用于接收用户输入信息的模块，和用于根据用户的输入生成对通信质量的评价数据，并将该评价数据发送到网络侧的模块；在网络侧内还包含用于对来自移动终端的评价数据进行统计并得到通信业务质量统计结果的模块。
由于发送给网络侧的评价数据是从用户对某项业务的实际感受转化而成的各种指标，因此，网络侧可以获得大量来自真实用户的样本，从而掌握网络实际服务质量，指导或验证网络的优化工作。如果网络侧经过统计判定某区域某业务异常，则可利用传统路测手段进行问题排查，进而有效提高网优效率并减少用户投诉。
其中，评价数据内包含与相应业务相关的各关键能力指标项，每个关键能力指标项分为不同等级，分别表示用户对通信质量的不同评价，清楚有效地表达了用户对某项业务的各项KPI的感受，且由于以较小的数据量表达了用户对通信质量的评价，使得该评价数据的发送不会为网络增加过多的负担。
本发明第五实施方式的移动终端，包含用于接收用户输入信息的模块，和用于根据用户的输入生成对通信质量的评价数据，并将该评价数据发送到网络侧的模块，供网络侧对通信业务质量进行统计。使得网络侧可以获得大量来自真实用户的样本，从而掌握网络实际服务质量，指导或验证网络的优化工作。
虽然通过参照本发明的某些优选实施方式，已经对本发明进行了图示和描述，但本领域的普通技术人员应该明白，可以在形式上和细节上对其作各种改变，而不偏离本发明的精神和范围。
