Description

丢失率的最小化路测MDT的方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种丢失率的最小化路测MDT的方法及装置。
背景技术
为了降低运营商利用专用设备进行人工路测的成本和复杂性，第三代伙伴组织计划(Third Generation Partnership Projects，简称为3GPP)在包括：基站Node B和无线网络控制器RNC的通用陆地无线接入网(Universal Terrestrial Radio Access Network，简称为UTRAN)和包括演进基站eNB的演进的通用陆地无线接入网(Evolved Universal Terrestrial Radio Access Network，简称为E-UTRAN)系统的版本10(Release-10)开始引入最小化路测(Minimization of Drive Test，简称为MDT)功能。
UTRAN对应的核心网(Core Network，简称为CN)包括宿主用户服务器(Home Subscriber Server，简称为HSS)也称位置寄存器、移动交换中心服务器(Mobile Switching Centre Server，简称为MSC Server)、服务的通用分组无线业务GPRS支持节点(Serving General Packet Radio Service Support Node，简称为SGSN)等。E-UTRAN对应的核心网CN包括：宿主用户服务器位置寄存器HSS、移动管理实体(Mobile Management Entity，简称为MME)等。最小化路测功能利用用户设备(User Equipment，简称为UE)自动收集测量信息通过控制面(Control Plane)信令报告给无线接入网(Radio Access Network，简称为RAN)，其中，对于UTRAN系统指RNC，对于E-UTRAN系统指eNB，再通过无线接入网报告给操作维护系统(Operation And Maintenance，简称为OAM)的跟踪收集实体(Trace Collection Entity，简称为TCE)，用于网络优化，例如：发现及解决网络覆盖问题。
MDT功能分为基于管理的MDT(Management based MDT)和基于信令的MDT(Signaling based MDT)；其中，基于管理的MDT的激活过程通常是(以E-UTRAN系统为例，以下均同)OAM发送包含MDT配置的跟踪激活消息(Trace Session Activation，简称为TSA)给eNB，eNB在该消息规定的区域(Area)内选择合适的UE，并将所述MDT配置信息发送给选中的UE。基于信令的MDT的激活过程是由OAM发送包含MDT配置的跟踪激活消息给归属用户服务器HSS以激活指定UE的MDT测量，位置寄存器HSS将所述UE的MDT配置信息发送给MME，MME将该UE的MDT配置信息发送给eNB，eNB最终将MDT配置信息发送给UE。基于信令 的MDT通常用国际移动用户标识(International Mobile Subscriber Identity，简称为IMSI)或国际移动站设备标识(International Mobile Station Equipment Identity，简称为IMEI)来指定某个UE，或加上区域信息以限制UE的选择。基于管理的MDT和基于信令的跟踪激活消息中包含来自OAM的跟踪参考(Trace Reference)信息，其中，包括公共陆地移动网络(Public Land Mobile Network，简称为PLMN)信息，由移动国家码(Mobile country code，简称为MCC)和移动网络码(Mobile Network code，简称为MNC)组成。
MDT功能按照其工作在空闲态和工作在连接态可以分为两种工作模式，具体为“记录最小化路测(Logged MDT)”和“立即最小化路测(immediate MDT)”；其中，记录最小化路测是指UE在无线资源控制空闲状态(对于E-UTRAN系统指RRC_IDLE状态；对于UTRAN系统还包括小区_寻呼信道状态CELL_PCH和UTRAN注册区_寻呼信道状态URA_PCH)。当所配置的条件满足时收集并存储相关测量信息用于将来收到无线接入网RAN命令要求时上报，无线接入网RAN收到数据后，汇总或者直接转发给TCE。立即最小化路测是指UE在无线资源控制连接状态(对于E-UTRAN系统指RRC_CONNECTED状态；对于UTRAN系统指小区_专用信道状态CELL_DCH)时收集相关测量信息并在报告满足上报条件时主动上传给无线接入网RAN，无线接入网RAN接收到报告后，汇总或者直接将报告传递给TCE。
MDT测量的目标是提供数据分析网络性能。MDT测量用于发现对网络性能影响的关键环节，发现是否有必要调整网络配置参数或者网络扩容。在网络早期部署或者大规模使用时，该功能均可以用来检测UE的服务质量(Quality of experience，简称为QoE)感受是否满足网络规划的要求。相关技术中的人工路测同样有测量的工作，但是人工路测的成本较高，而且有些特定的区域是无法使用人工路测充分测量的。因此MDT测量采用一定数量的UE上报使用业务时的实测数据，为运营商提供有统计意义的测量数据。
相关技术中服务质量QoS被用来表示业务的实际传输情况，总计有九种不同的QoS，以服务质量类别标识(QoS Class Identifier，简称为QCI)表示，每种QCI都有规范的属性值，例如最大时延要求(Packet Delay Budget，简称为PDB)，丢失率(Packet Error Loss Rate，简称为PELR)，优先级Priority等。相关技术中，每个终端都可以有若干个无线接入承载，每个无线接入承载一一对应一个无线承载，每个无线接入承载都有一个对应的QCI，也就是说每个无线承载都有一个对应的QCI，例如E-UTRAN系统中，无线接入承载E-RAB和无线承载RB有且仅有相同的QCI。
LTE网络支持不同的业务,例如多媒体电话业务(MultiMedia Telephony，简称为MMTEL)，这种业务包括支持电话，视频，短消息等各种形式。运营商在部署业务 时，还需要考察该业务的实际运行情况，使用MDT测量MMTEL业务的部署和使用情况就显得较为重要，但是相关技术中终端还没有关于针对于MMTELD的MDT测量。
针对相关技术中终端无法提供丢失率最小化路测MDT测量的问题，目前尚未提出有效的解决方案。

下面结合附图和本发明的可选实施例对本发明进行举例说明；
可选实施例一
本可选实施例用于说明基于信令MDT的立即最小化路测中，基站如何实现时延MDT测量。
图3是根据本发明可选实施例的基于信令的MDT的测量方法的示意图，在本可选实施例中MDT功能处于立即MDT的工作模式下的最小化路测MDT，如图3所示，该方法的步骤包括：
步骤S302：网管系统EMS触发最小化路测，发送最小化路测配置消息；
其中，该消息可以是跟踪会话激活(Trace Session Activation简称为TSA)消息给位置寄存器HSS网元，其中，该消息中包含触发获取某终端MMTEL业务丢失率的测量要求；
步骤S304：位置寄存器HSS检索到UE进入附着状态后，发送最小化配置消息给UE所在的核心网元；
其中，如果是E-UTRAN网络情况下，核心网元为MME；如果是UTRAN网络情 况，核心网元为SGSN或者是MSC server；例如：核心网元为MME时，携带MDT配置的消息是更新位置应答(Update location answer)消息，其中，该消息中包含触发获取延迟的测量要求；
步骤S306：核心网元发送最小化路测配置消息给接入网元；
其中，如果是E-UTRAN网络情况下，接入网元为eNB，携带最小化路测配置的消息为初始上下文建立请求(Initial context setup request)消息；如果是UTRAN PS域，接入网元为RNC，携带最小化路测配置的消息为核心网请求跟踪(CN invoke Trace)消息；消息中包含触发获取位置信息的测量要求；或者核心网元发送专门的消息包含获取丢失率的测量要求；
步骤S308：接入网元接受最小化路测配置消息，通过RRC消息最小化路测消息配置给终端；
其中，配置中包含丢失率的测量对象，丢失率的测量周期，丢失率的测量触发条件等配置；
步骤S310：终端根据配置执行丢失率的最小化测量；
终端接受MDT配置后，识别包含获取丢失率的测量要求，根据配置启动对上行和或下行的测量，测量对象包括根据特定QCI，特定承载和或整个终端的丢失率测量；
如果配置中包含丢失率测量触发条件，则需要等待MMTEL相关的业务开始后才开始进行丢失率测量，在MMTEL业务终止时也同时终止相应的丢失率测量。例如配置中指示仅针对MMTEL的语音业务进行测量，终端可以根据非接入层协议(NAS)获得MMTEL类型对应的承载信息和QCI信息，则终端可以在MMTEL对应的承载建立时或对应的QCI归属的承载建立时才启动丢失率测量；
该上行丢失率测量和下行丢失率测量可以同时进行；
步骤S312：终端上报MDT测量结果给基站；
其中，终端通过RRC消息上报MDT测量结果给基站；
步骤S316：基站上报MDT测量结果。
其中，基站向跟踪收集实体(Trace Collection Entity，简称为TCE)上报终端的丢失率测量结果。
可选实施例二
本可选实施例用于说明基于管理MDT的立即最小化路测中，终端如何实现丢失 率的MDT测量。
图4是根据本发明可选实施例的基于管理的MDT测量方法的示意图，在本可选实施例中MDT功能处于立即最小化路测MDT的工作模式下，如图4所示，该方法的步骤包括：
步骤S402：网管系统EMS触发最小化路测，通过南向接口将配置请求(最小化路测配置消息)发送给接入网网元，例如：eNB或RNC；该消息中包含了获取MMTEL业务丢失率信息的测量要求；
步骤S404：接入网元选择合适的终端，并发送MDT配置消息给终端；本实施例是基于管理的MDT，接入网eNB或者RNC选择合适的一个或者多个终端；接入网通过现有消息将MDT配置信息发送给终端，该消息包含获取MMTEL业务丢失率信息的测量要求；
基站向终端配置的信息消息是采用和无线资源管理测量相关相同的消息，具体的，在E-UTRAN网络中，可以是无线资源控制(Radio Resource Control，简称为RRC)连接重配置消息。
步骤S406：终端接受最小化路测配置消息后启动针对MMTEL业务的丢失率测量；
终端接受MDT配置后，识别包含获取丢失率的测量要求，根据配置启动对上行和或下行的测量，测量对象包括根据特定QCI，特定承载和或整个终端的丢失率测量；
如果配置中包含丢失率测量触发条件，则需要等待MMTEL相关的业务开始后才开始进行丢失率测量，在MMTEL业务终止时也同时终止相应的丢失率测量。例如配置中指示仅针对MMTEL的语音业务进行测量，终端可以根据非接入层协议(NAS)获得MMTEL类型对应的承载信息和QCI信息，则终端可以在MMTEL对应的承载建立时或对应的QCI归属的承载建立时才启动丢失率测量；
根据配置，终端可以同时开启上行和下行测量，或者只进行上行或下行测量。
步骤S408：终端将测量结果通过基站上报至跟踪收集实体TCE。
终端可以根据自己的测量情况选择上报，也可以结合其他测量再上报，例如终端提供了位置信息后，终端可以将其所测量的丢失率结果和位置信息结合起来一起上报；基站根据终端的报告提供给TCE。
可见，本实施例可以支持终端实施针对QCI或者承载或者终端的各种丢失率和丢弃率的测量，并将测量结果上报到网络；此外，本实施例的方法可支持上行和/或下行的测量，以满足MDT的实际需求。
在另外一个实施例中，还提供了一种存储介质，该存储介质中存储有上述软件，该存储介质包括但不限于：光盘、软盘、硬盘、可擦写存储器等。
显然，本领域的技术人员应该明白，上述本发明的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
上述仅为本发明的可选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
