人工驱车路测的方式费时费力，第三代伙伴计划(3rd generation partnership project，3GPP)标准化组织在长期演进(long term evolution，LTE)系统研究并标准化了最小化路测(minimization of drive tests，MDT)技术，MDT技术是通信系统实现自动化采集和分析含位置信息的测量报告的技术，用于减小人工路测的工作量，减少网络设备维护的成本，同时也解决移动网络质量评估工作中的实时性和广泛性问题。
MDT技术中需要终端设备上报MDT数据，由于MDT数据中携带有位置信息，涉及用户的安全和隐私问题，可能存在巨大的准入风险，因此，如何在实现MDT数据上报的同时，保护用户的安全和隐私成为了一个亟待解决的问题。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信系统，例如：长期演进(long term evolution，LTE)系统、LTE频分双工(frequency division duplex，FDD)系统、LTE时分双工(time division duplex，TDD)、第五代(5th generation，5G)系统或新无线(new radio，NR)，后续演进系统，各种通信系统的融合系统，物联网系统，以及车联网系统等等。

本申请实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定，只要能够通过运行记录有本申请实施例的提供的方法的代码的程序，以根据本申请实施例提供的方法进行通信即可，例如，本申请实施例提供的方法的执行主体可以是终端设备或网络 设备，或者，是终端设备或网络设备中能够调用程序并执行程序的功能模块。
另外，本申请的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于:磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，压缩盘(compact disc，CD)、数字通用盘(digital versatile disc，DVD)等)，智能卡和闪存器件(例如，可擦写可编程只读存储器(erasable programmable read-only memory，EPROM)、卡、棒或钥匙驱动器等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
图1是本申请实施例提供技术方案的应用场景的示意图，如图1所示，终端130接入到无线网络，以通过无线网络获取外网(例如因特网)的服务，或者通过无线网络与其它终端通信。该无线网络包括RAN110和核心网(CN)120，其中RAN110用于将终端130接入到无线网络，CN120用于对终端进行管理并提供与外网通信的网关。
应理解，本申请提供的通信方法可适用于无线通信系统，例如，图1中所示的无线通信系统100。处于无线通信系统中的两个通信装置间具有无线通信连接，该两个通信装置中的一个通信装置可对应于图1中所示的终端130，例如，可以为图1中的终端130，也可以为配置于终端130中的芯片；该两个通信装置中的另一个通信装置可对应于图1中所示的RAN110，例如，可以为图1中的RAN110，也可以为配置于RAN110中的芯片。
图2是本申请实施例提供的一种网络架构的示意图，如图2所示，该网络架构包括CN设备和RAN设备。其中RAN设备包括基带装置和射频装置，其中基带装置可以由一个节点实现，也可以由多个节点实现，射频装置可以从基带装置拉远独立实现，也可以集成基带装置中，或者部分拉远部分集成在基带装置中。例如，在LTE通信系统中，RAN设备(eNB)包括基带装置和射频装置，其中射频装置可以相对于基带装置拉远布置，例如射频拉远单元(remote radio unit，RRU)相对于BBU拉远布置。
RAN设备和终端之间的通信遵循一定的协议层结构。例如控制面协议层结构可以包括无线资源控制(radio resource control，RRC)层、分组数据汇聚层协议(packet data convergence protocol，PDCP)层、无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理层等协议层的功能。用户面协议层结构可以包括PDCP层、RLC层、MAC层和物理层等协议层的功能；在一种实现中，PDCP层之上还可以包括业务数据适配(service data adaptation protocol，SDAP)层。
RAN设备可以由一个节点实现无线资源控制(radio resource control，RRC)、分组数据汇聚层协议(packet data convergence protocol，PDCP)、无线链路控制(radio link control，RLC)、和媒体接入控制(media access control，MAC)等协议层的功能；或者可以由多个节点实现这些协议层的功能；例如，在一种演进结构中，RAN设备可以包括集中单元(centralized unit，CU)和分布单元(distributed unit，DU)，多个DU可以由一个CU集中控制。如图2所示，CU和DU可以根据无线网络的协议层划分，例如PDCP层及以上协议层的功能设置在CU，PDCP以下的协议层，例如RLC层和MAC层等的功能设置在DU。
这种协议层的划分仅仅是一种举例，还可以在其它协议层划分，例如在RLC层划分， 将RLC层及以上协议层的功能设置在CU，RLC层以下协议层的功能设置在DU；或者，在某个协议层中划分，例如将RLC层的部分功能和RLC层以上的协议层的功能设置在CU，将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU。此外，也可以按其它方式划分，例如按时延划分，将处理时间需要满足时延要求的功能设置在DU，不需要满足该时延要求的功能设置在CU。
此外，射频装置可以拉远，不放在DU中，也可以集成在DU中，或者部分拉远部分集成在DU中，在此不作任何限制。
请继续参考图3，图3示出了本申请实施例提供的另一种网络架构的示意图，相对于图2所示的架构，还可以将CU的控制面(CP)和用户面(UP)分离，分成不同实体来实现，分别为控制面CU实体(CU-CP实体)和用户面CU实体(CU-UP实体)。
在以上网络架构中，CU产生的信令可以通过DU发送给终端，或者终端产生的信令可以通过DU发送给CU。DU可以不对该信令进行解析而直接通过协议层封装而透传给终端或CU。以下实施例中如果涉及这种信令在DU和终端之间的传输，此时，DU对信令的发送或接收包括这种场景。例如，RRC或PDCP层的信令最终会处理为PHY层的信令发送给终端，或者，由接收到的PHY层的信令转变而来。在这种架构下，该RRC或PDCP层的信令，或者，也可以认为是由DU发送的，或者，由DU和射频发送的。
在以上实施例中CU划分为RAN侧的网络设备，此外，也可以将CU划分为CN侧的网络设备，在此不做限制。
本申请以下实施例中的装置，根据其实现的功能，可以位于终端。当采用以上CU-DU的结构时，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的RAN设备。
在介绍本申请实施例的技术方案之前，首先介绍几个与本申请实施例相关的概念。
匿名传输：终端设备采用匿名的方式来传输需要通过匿名方式传输的数据给网络设备，例如，建立匿名连接，不需要网络认证鉴权终端设备。可以理解的是，匿名传输也可以叫做建立匿名RRC连接，也可以描述为使用匿名方式传输数据，或者可以描述为传输匿名数据，或者当匿名数据包括MDT数据时，也可以描述为传输MDT数据等，本申请实施例对此不做限定。
MDT数据：在运营商有路测需求的时候，根据某些特定条件选择终端设备参加MDT数据上报，上报的内容主要是RAN方面及服务质量(quality of service，QoS)相关的数据。
MDT数据能够给运营商提供实时的网络质量评估数据，对于及时发现网络问题，进行网络优化等工作都有很大的帮助。特别是该功能能大大减少路测的需求，对降低运营成本有很重大的意义。
图4示出了本申请实施例提供的一种通信方法200的示意性流程图，如图4所示，该方法200包括：

S220，该网络设备确定终端设备建立RRC连接是为了匿名传输数据，不进行与核心网的交互。
具体而言，网络设备在获知是匿名传输后，与传统的RRC连接不同的是，网络设备可以不建立与核心网的终端设备的连接，例如，不与核心网进行交互，不识别用户的身份，或者，不对终端设备进行认证或鉴权，而是在未识别用户身份的情况下，直接进行空口的匿名数据传输。
应理解，终端设备向网络设备上报的数据或者信令中均不携带终端设备的标识信息，或者，终端设备向网络设备上报的数据或者信令中均不携带识别用户身份的标识信息，即使网络设备和核心网设备之间建立了连接，网络设备和核心网也不会获知终端设备的身份，从而也可以达到匿名的效果。
S230，该终端设备在与该网络设备建立该RRC连接后，向该网络设备发送需要通过匿名方式传输的数据。

应理解，该RRC重配置消息中包括建立DRB的信元，该信元用于指示终端设备建立DRB。
S222，该终端设备向该网络设备发送RRC重配置完成(RRC reconfiguration complete)消息。
可选地，该向该网络设备发送需要通过匿名方式传输的数据之后，该方法200还包括：
S231，该网络设备将该需要通过匿名方式传输的数据递交到特定的协议层进行处理；
S232，该终端设备向该网络设备发送数据传输完成消息，或者，该终端设备向该网络设备发送RRC连接释放请求(RRC release request)消息；
S233，该网络设备释放该匿名RRC连接，该终端设备进入空闲态。
具体而言，该网络设备可以向该终端设备发送RRC连接释放消息，该终端设备收到该RRC连接释放消息后，断开与该匿名RRC连接，从而进入空闲态。
可选地，该需要通过匿名方式传输的数据包括MDT数据。
应理解，本申请实施例中，该需要通过匿名方式传输的数据可以为MDT数据，也可以为其他数据，还可以为MDT数据和其他数据的组合，本申请实施例对此并不作任何限定。
还应理解，方法200中仅仅给出了终端设备与网络设备建立匿名RRC过程的一种可 能的实现，终端设备与网络设备建立匿名RRC连接的过程并不限于以上实现方式，还可能是其他可能的实现方式，本申请实施例对此并不作任何限定。
以上通过图4介绍了本申请实施例提供的通信方法200，该方法200解决了终端设备与网络设备之间建立匿名RRC连接的问题，下面通过图5介绍本申请实施例的通信方法300，由于数据传输是通过匿名的方式，方法300主要解决如何选择终端设备进行匿名传输的问题。
图5示出了本申请实施例提供的通信方法300的示意性流程图，如图5所示，该方法300包括：
S310，网络设备向终端设备发送第一指示信息。
该终端设备接收该网络设备发送的该第一指示信息，该第一指示信息用于指示该终端设备上报第一数据。

可选地，该第一数据包括MDT数据。
可选地，该网络设备向终端设备发送第一指示信息之前，该方法300还包括：

例如，网络设备可以在一个时间段内或者某一个事件触发时，确定需要收集第一数据，然后向该终端设备发送该第一指示信息。
又例如，上述时间段可以是夜晚网络设备的负载较轻时，上述事件触发可以是某一个地区的网络质量突然变差。
又例如，网络设备可以周期性地收集该第一数据，当进入收集第一数据的周期时，该网络设备向该终端设备发送该第一指示信息。

隐式指示：该第一指示信息中包括一个字段，该字段为用户选择配置信息，终端设备收到该第一指示信息后，可以隐式获知网络设备希望其上报第一数据。
可选地，也可以是该第一指示信息包括用于指示上报该第一数据的字段，但是不包括用户选择配置信息，那么终端设备根据收到的该第一指示信息确定需要与该网络设备建立 该匿名RRC连接。
应理解，本申请实施例中，由于第一数据包括需要通过匿名方式传输的数据，该用户选择配置信息不包含确定一个特定终端设备的信息，例如，终端设备的标识信息，从而达到匿名的有益效果。
可选地，用户选择配置信息包括概率信息和/或选择条件。
可以理解的是，用户选择配置信息也可以叫终端选择配置信息，或者选择配置信息。
应理解，本申请实施例中，“被选中”可以理解为“终端设备被选中与网络设备建立该匿名RRC连接”，或者，也可以理解为“终端设备被选中上报该第一数据”。那么，“未被选中”可以理解为“终端设备不能与网络设备建立该匿名RRC连接”，或者，也可以理解为“终端设备不能上报该第一数据”。
例如，如果该用户选择配置信息包括概率信息，那么该终端设备根据该用户选择配置信息，确定与该网络设备建立该匿名RRC连接，包括：
获取随机值；
在该随机值和该概率信息满足预设条件的情况下，确定与该网络设备建立该匿名RRC连接。该预设条件包括但不限于：
(1)该随机值与可以产生的最大随机值的比例小于或者等于被选中的概率；
(2)该随机值与可以产生的最大随机值的比例大于或者等于不被选中的概率。
可选地，该概率信息为一个比例，比如百分比，用于指示被选中的概率或者不被选中建立匿名RRC连接的概率，终端设备通过随机值的方式来确定是否被选中建立匿名RRC连接。
例如，该概率信息指示终端设备被选中的概率为40％，终端设备可以随机产生100以内的整数，若产生的整数位于40以内，则被选中；若产生的整数位于40和100之间，则不被选中。
又例如，该概率信息指示该终端设备不被选中的概率为50％，终端设备可以随机产生100以内的整数，若产生的整数位于50以内，则不被选中；若产生的整数位于50和100之间，则被选中。
应理解，以上举例中被选中的概率和不被选中的概率也可以用其他形式表示，例如，被选中的概率为0.4或者2/5，不被选中的概率为0.5或者1/2。
可选地，一种可能的实现中，终端设备和网络设备可以提前约定该概率信息为被选中的概率或者为不被选中的概率。
应理解，本申请实施例中，该随机值还可以是终端设备自己产生的，也可以是终端设备从其他设备处获取的，本申请实施例对此并不作任何限定。
还应理解，本申请实施例中，该概率信息除了可以理解为是一个数值，还可以理解为是一个门限，例如，当终端设备获取的随机值大于或者等于该门限时，该终端设备确定被选中。
例如，如果该用户配置信息包括选择条件，该选择条件包括第一区域的位置信息，该终端设备根据该用户选择配置信息，确定与该网络设备建立该匿名RRC连接，包括：
在该终端设备位于该第一区域的情况下，确定与该网络设备建立该匿名RRC连接。

可选地，该第一区域也可以为一个圆形区域，例如，该第一区域的位置信息可以包括该圆形区域的中心点的位置和该圆形的半径信息。
可选地，该选择条件也可以是包括第一类型的信息，该第一类型是终端设备的某一类或者某几类类型信息，该终端设备根据该用户选择配置信息，确定与该网络设备建立该匿名RRC连接，包括：
在该终端设备为该第一类型的终端设备的情况下，确定与该网络设备建立该匿名RRC连接。
可选的，该第一类型的终端设备包括但不限于以下几种类型的一种或者多种：
(1)MDT签约的终端设备；
(2)能量不敏感的终端设备；
(3)物联网(internet of things，IoT)的终端设备；
(4)保存有某类MDT数据的终端设备。
例如，该能量不敏感的终端设备可以为固定位置的终端设备，例如，总是连接电力或正在充电的终端设备。
又例如，保存有某类MDT数据的终端设备可以为保存有失败MDT日志的终端设备，或者，保存有周期MDT日志的终端设备等等。
应理解，以上仅仅对能量不敏感的终端设备和保存有某类MDT数据的终端设备进行了举例说明，本申请并不限于此。
还应理解，本申请实施例中，该第一类型的终端设备可以为以上几种类型中的任意一种类型或者为以上几种类型的任意组合。
还应理解，还可以将该概率信息、第一区域的位置信息和第一类型的终端设备的信息中的任意几种组合在一起判断终端设备是否被选中，例如，可以将概率信息和第一区域的位置信息相结合，该第一指示信息可以指示能量不敏感的终端设备被选中的概率为40％，该终端设备被选中需要满足两个条件：①该终端设备为能量不敏感的终端设备；②该终端设备在100以内产生的随机数位于40以内。
还应理解，本申请实施例的用户选择配置信息还可以为其他信息，或者为其他信息、概率信息和/或选择条件的组合，例如，该其他信息可以为该终端设备的功耗信息，例如，可以为一个功耗阈值，当该终端设备接收到该第一指示信息后，可以确定该终端设备当前的功耗，当该功耗小于或者等于该功耗阈值时，该终端设备可以被选中，否则不能被选中。
本申请实施例的通信方法，通过在第一指示信息中携带用户选择配置信息，有助于终端设备明确是否与网络设备建立匿名RRC连接，通过设置用户选择配置信息，网络设备能选择合适的终端设备上报第一数据。
本申请实施例中，还可以采用定时器机制来避免终端设备频繁进行数据的传输，从而节省终端设备的功耗。
可选地，该终端设备根据该第一指示信息，确定与该网络设备建立该匿名RRC连接之前，该方法300还包括：
该终端设备确定第一定时器未运行，该第一定时器的状态可以用于该终端设备确定是否与该网络设备建立该匿名RRC连接。
例如，如果一个终端设备已经上报了MDT数据，也就是说如果一个终端设备建立过匿名RRC连接，则在一定的时间内可以忽略掉该第一指示信息。例如，可以在每次确定需要发起匿名RRC连接建立时，或者每次在释放匿名RRC连接时，启动第一定时器，在该第一定时器运行期间，终端设备如果再次接收到第一指示信息，则忽略掉该第一指示信息。例如，每次在确定是否需要发起匿名RRC连接建立时或者说接收到第一指示信息时，如果该第一定时器还在运行，则该终端设备忽略掉该第一指示信息，否则根据S320中的方法来确定是否被选中。可选地，第一指示信息还可以包括该第一定时器的时长。其中，由于在一定时间内，第一指示信息被忽略掉，也可以理解为，如果终端设备在一定时间内再次接收到第一指示信息，不再根据再次接收到的第一指示信息执行相应的操作。
可选地，该终端设备确定与该网络设备建立该匿名RRC连接后，所述方法还包括：
该终端设备启动该第一定时器，该第一定时器的状态用于该终端设备下一次接收到该第一指示信息后，确定是否与该网络设备建立匿名RRC连接。
具体而言，该终端设备可以在与该网络设备建立该匿名RRC连接后，启动该第一定时器，若在发送第一数据之后再一次接收到上报需要通过匿名方式传输数据的指示信息，则可以先判断该第一定时器是否超时，如果该第一定时器超时，那么该终端设备可以建立与该网络设备的匿名RRC连接，否则不建立与该网络设备的匿名RRC连接。
应理解，本申请实施例中，该第一定时器未运行，还可以理解为该第一定时器超时，该第一定时器运行，还可以理解为该第一定时器未超时。
还应理解，定时器的状态可以为“运行”或者“未运行”，而造成定时器“未运行”这种状态的一种场景可以是“超时”。
还应理解，本申请实施例中该第一定时器开始启动的时刻可以是终端设备确定与该网络设备建立匿名RRC连接时，也可以是该终端设备与该网络设备建立好该匿名RRC连接时，还可以是该终端设备开始或者结束向该网络设备发送该第一数据时，还可以是终端设备释放该匿名RRC连接时，本申请对该定时器启动的时刻不作任何限定。
还应理解，该第一定时器的时长可以是网络设备配置的，也可以是预设的，本申请实施例对此并不作任何限定。
本申请实施例的通信方法，通过定时器机制，能避免终端设备频繁进行数据的传输，从而节省终端设备的功耗。
可选地，该第一指示信息中还可以包括延迟建立配置信息，该延迟建立配置信息用于终端设备确定匿名RRC连接建立的时间点。
应理解，本申请实施例中是以该用户选择配置信息、延迟建立配置信息等信息包括在该第一指示信息中为例进行说明，该用户选择配置信息、延迟建立配置信息等信息也可以不包括在第一指示信息中，而是在其他信息或者消息中分别下发给终端设备，本申请实施例对此并不作任何限定。
一种可能的方式中，网络设备发送的该第一指示信息可能会触发多个终端设备被选中来进行匿名RRC连接建立，如果这些终端设备全部立即发起连接建立，会造成随机接入过程冲突概率增加，造成对于网络的信令冲击。因此可以考虑一种延迟建立机制。该第一指示信息中可以携带延迟建立配置信息，或者协议规定延迟建立配置信息，比如，基于随机值或终端设备的标识信息等的延迟建立配置信息，从而使得终端设备可以获取各自不同 的匿名RRC连接建立的时间点或延迟RRC连接建立的时长，使终端设备尽量分散建立该匿名RRC连接。
例如，该延迟建立机制可以为基于随机值的延迟建立配置信息，该延迟建立配置信息包含延迟建立的最长时间或时间范围，或协议规定延迟建立的最长时间或时间范围。终端设备产生随机值，通过随机值确定匿名RRC连接建立的时间点。
例如，最长时间为1分钟，终端设备可以产生100以内的随机数，每一个随机数对应一个延迟建立匿名RRC连接的时间点。
一种可能的实现方式是，终端设备可以通过获取的随机值得到对应于该随机值的一个百分比，60秒*百分比得到延迟的时长。比如随机值为0，则立即发起，随机值为40，则百分比为40％，则60秒*40％＝24秒，则延迟24秒后建立该匿名RRC连接。
又例如，最长时间为2秒，终端设备可以产生100以内的随机数，产生随机值在0～30的终端设备可以立即建立匿名RRC连接，产生随机值在31～60的终端设备可以在收到该第一指示信息后延迟1秒建立匿名RRC连接，产生随机值在61～100的终端设备可以在收到该第一指示信息后延迟2秒建立匿名RRC连接。
又例如，最长时间为1分钟，终端设备的标识信息为该终端设备的ID，终端设备可以根据求余函数mod(ID，divisor)得到的数值，确定对应的匿名RRC连接建立的时间点，其中，divisor可以为预设的除数。
本申请实施例的通信方法，通过在该第一指示信息中携带延迟建立配置信息，在多个终端设备都要与网络设备建立匿名RRC连接的情况下，有助于将多个终端设备在不同的时间点，与网络设备建立连接，从而有助于降低对网络的信令冲击。
可选地，该终端设备确定与该网络设备建立该匿名RRC连接之前，该方法200还包括：
该终端设备确定处于空闲态或者去活动态。
在NR系统中，包括3种RRC状态，分别为空闲(idle)态，连接(connected)态和去活动(inactive)态。其中，空闲态下，终端设备与网络设备没有建立RRC连接，并且终端设备没有保存空口的RRC连接配置的状态；连接态下，终端设备与网络设备建立了RRC连接的状态；去活动态下，终端设备与网络设备没有建立RRC连接，但是终端设备保存空口的RRC连接配置的状态。例如，对于连接态的终端设备，已经建立了与网络设备的RRC连接；对于去活动态的终端设备，其保存了终端设备的上下文信息。
可选地，一种可能的方式中，以上方案适用于空闲态的终端设备，也就是说，空闲态的终端设备可以通过上述方案确定自己是否被选中。
可选地，另一种可能的方式中，以上方案适用于空闲态或者去活动态的终端设备，也就是说，空闲态或者去活动态的终端设备可以通过上述方案确定自己是否被选中。
可选地，对于完成匿名连接建立的终端设备，可以引入一个新的RRC状态来标识，比如RRC匿名态，用于表示终端设备与网络设备建立了匿名RRC连接的状态。可以理解的是，也可以将RRC匿名态看作是空闲态或者去活动态的一种子状态。
对于发起匿名RRC连接的终端设备或者RRC匿名态的终端设备，由于网络设备不知道终端设备的身份，认为终端设备仍然在空闲态或者去活动态，因此当有下行数据需要发送给该终端设备时，网络设备可以发送寻呼消息以寻呼该终端设备，可选地，该寻呼消息 中携带该终端设备的标识信息。
一个实施例中，发起匿名RRC连接建立过程中和进入到RRC匿名态的终端设备仍然监听寻呼消息，并确定寻呼消息中是否包含自己的标识信息来确定是否被寻呼。如果被寻呼，或者终端设备自己有上行数据要发送时，例如，上行数据不是第一数据，则终端设备可以断开匿名RRC连接，例如进入到空闲态，然后发起普通的RRC连接建立过程进入到连接态。例如，该普通的RRC连接建立过程中，核心网通过对终端设备进行鉴权或认证，获知终端设备的标识信息。终端设备建立普通的RRC连接的优先级高于终端设备建立匿名RRC连接或者进行第一数据传输的优先级。可选的，断开匿名RRC连接比如可以包括：终端设备请求网络释放匿名RRC连接，或者终端设备通知网络设备该终端设备将释放RRC连接。
S330，在该终端设备与该网络设备建立该匿名RRC连接后，该终端设备向该网络设备发送该第一数据。
相应的，该网络设备接收该终端设备发送的该第一数据。
此处，该终端设备确定该终端设备被选中，与该网络设备建立匿名RRC连接，向该网络设备发送该第一数据。
需要说明的是，本申请实施例对终端设备与网络设备建立匿名RRC连接的方式不作限定，也就是说任何可以实现终端设备建立与网络设备的匿名的方式均可以实现本申请实施例。
应理解，本申请实施例中，该第一指示信息中可以包括用户选择配置信息，延迟建立配置信息，该第一定时器的时长(或者，下文所涉及的信息)等等信息中的一种或者组合，另一种可能的实现方式中，用户选择配置信息，延迟建立配置信息，该第一定时器的时长等等信息可以携带在不同的信息中同时下发给终端设备，或者，采用一定的先后顺序分别下发给终端设备，本申请实施例中对此不作任何限定。
本申请实施例的通信方法，通过在第一指示信息中携带用户选择配置信息，有助于终端设备明确是否需要发起匿名RRC连接。

在现有技术中，如果需要寻呼终端设备建立RRC连接，都是在寻呼paging消息中携带终端设备的标识信息来进行寻呼。本申请实施例中，网络设备可以不通过终端设备的标 识信息来寻呼，而是在寻呼消息中携带第一指示信息，终端设备收到该第一指示信息后，可以基于该第一指示信息确定是否需要发起匿名RRC连接建立。

其中，bit 1置为1表示系统消息发生了改变，可以理解的是，也可以是bit 1置为0表示系统消息发生了改变，本申请实施例对bit具体取值的含义不做限定。
本申请实施例中，当网络设备需要通过系统消息发送第一指示信息时，可以发送bit 1 置为1的短消息，从而触发终端设备读取系统信息来获取到该第一指示信息，也可以使用一个其他bit，比如bit 3中的一位或者多位，例如将bit 3中某一位置为1来表示网络设备发送该第一指示信息，从而触发终端设备读取系统信息来获取到该第一指示信息。

显式指示：该第一指示信息包括两个字段，一个字段用于指示上报已经保存的需要通过匿名方式传输的数据，另一个字段为需要通过匿名方式传输的数据的类型的信息。
隐式指示：该第一指示信息中包括一个字段，该字段为需要通过匿名方式传输的数据 的类型的信息，终端设备收到该第一指示信息后，可以隐式获知网络设备希望其上报已经保存的需要通过匿名方式传输的数据。

例如，对于隐式指示的方式，网络设备可以采用bitmap指示，bitmap中的每一个bit对应一种日志类型，一种可能的实现方式是，bitmap中的每个bit取值为1时代表对应的日志类型上报，为0时代表对应的日志类型不上报。如果需要通过匿名方式传输的数据的类型包括失败MDT日志和周期MDT日志，在bitmap取值为11的情况下，该bitmap指示终端设备上报的日志类型为失败MDT日志和周期MDT日志；在bitmap取值为10的情况下，该bitmap指示终端设备上报的日志类型为失败MDT日志；在bitmap取值为01的情况下，该bitmap指示终端设备上报的日志类型为周期MDT日志。

该终端设备接收该网络设备发送的该第一指示信息，该第一指示信息用于指示允许该终端设备主动上报第一数据。
可选地，该第一数据包括需要通过匿名方式传输的数据。
本申请实施例中，该第一指示信息用于指示允许终端设备主动上报第一数据时，终端设备可以自己决定上报，例如，终端设备可以自己选择合适的时机上报该第一数据。
可以理解的是，对于网络设备如何将第一指示信息发送给终端设备，可以进一步参考前述方法实施例的相关描述。
可选地，该第一指示信息包括该第一数据的上报条件。
例如，当该终端设备的失败日志的数量达到第一数值时，该终端设备可以主动上报该第一数据。
又例如，当该终端设备保存有失败的日志时，可以主动上报该第一数据。
本申请实施例中，该第一指示信息指示允许终端设备主动上报第一数据可以通过隐式指示和显式指示两种方式：
显式指示：该第一指示信息包括两个字段，一个字段用于指示允许终端设备主动上报第一数据，另一个字段为该第一数据的上报条件。
隐式指示：该第一指示信息中包括一个字段，该字段为该第一数据的上报条件，终端设备收到该第一指示信息后，可以隐式获知网络设备希望其主动上报第一数据。
可选地，也可以是该第一指示信息包括用于指示允许终端设备主动上报第一数据的字段，但是不包括该第一数据的上报条件，那么该终端设备根据收到的该第一指示信息，确定与该网络设备建立该匿名RRC连接。
S920，在满足主动上报的条件时，该终端设备确定与该网络设备建立匿名RRC连接。
例如，该第一指示信息中包括的上报条件为失败的日志数量达到10条，如果该终端设备接收到该第一指示信息时只有5条失败的日志，则该终端设备还不满足上报条件，当该终端设备保存的失败的日志达到10条时，该终端设备可以主动上报这10条失败的日志，并将统计的失败的日志的数量归0，以后当终端设备保存的失败的日志每达到10条时， 就可以选择主动上报。
S930，该终端设备在与该网络设备建立该匿名RRC连接后，向该网络设备发送该第一数据。
本申请实施例中，方法900区别于上述方法300中的用户选择配置信息的地方在于方法300中网络设备通过用户选择配置信息选择终端设备去上报第一数据，而方法900中网络设备可以允许终端设备主动上报第一数据，终端设备可以自己决定是否上报该第一数据。
应理解，终端设备确定与该网络设备建立RRC连接后，会进行建立匿名RRC连接的过程，本申请实施例对如何建立匿名RRC连接的过程不做限定，例如可以参考方法200的相关描述。
还应理解，该第一指示信息中可以同时包括上述方法300中的用户选择配置信息和方法900中的上报条件。
本申请实施例的通信方法，当该网络设备需要终端设备主动上报需要通过匿名方式传输的数据时，可以向该终端设备发送第一指示信息，以使终端设备主动通过匿名RRC连接上报该数据。
一个实施例中，对于图8至图12所示的几种场景，终端设备可以在发起匿名RRC连接时，向该网络设备发送信息指示匿名RRC连接建立的触发场景，包括：终端设备主动进行匿名传输，或者，该终端设备根据该网络设备的请求发起匿名传输，例如，基于该第一配置信息和该第二配置信息进行的匿名传输。
可选地，终端设备可以在RRC连接请求消息或者RRC连接建立完成消息中携带该终端设备主动或者根据该网络设备的请求发起匿名传输的信息。
以上结合图8至图12介绍了终端设备需要发起匿名RRC连接的几种场景，以下结合图13介绍终端设备在上报该第一数据时的安全保护机制。
图13示出了本申请实施例的通信方法1000的示意性流程图，如图13所示，该方法1000包括：
S1010，网络设备向终端设备发送第二消息，该终端设备接收该网络设备发送的该二消息，该第二消息包括第一指示信息，该第一指示信息用于指示终端设备上报第一数据。
可选地，该第一数据包括需要通过匿名方式传输的数据。
可选地，该第二消息还可以包括第三指示信息，该第三指示信息包括第一公钥。终端设备使用第一公钥对发送给网络设备的第一数据进行加密。可选地，第一公钥是网络设备的公钥。
可选地，该第二消息为系统消息。
可选地，该系统消息可以和上述方法500中的系统消息为同一系统消息，也可以为不同的系统消息，本申请实施例对此并不作任何限定。
本申请实施例中方法1000的主要是关于匿名传输的空口安全保护机制，考虑到是匿名传输，网络设备不知道终端设备的身份，可以采用非对称密钥机制来进行安全保护。
非对称密钥机制需要两个密钥：公钥(public key)和私钥(private key)。公钥与私钥是一对，如果用公钥对数据进行加密，只有用对应的私钥才能解密；通信的双方交换公钥，使用时一方用对方的公钥加密，另一方即可用自己的私钥解密。
对于匿名传输，可以通过小区广播(例如，系统消息)、或安全模式命令(security mode command)消息等将网络设备的公钥发送给终端设备，终端设备使用网络设备的公钥对发送给网络设备的第一数据进行加密。网络设备在收到终端设备发送的第一数据后，使用与该公钥对应的的私钥进行解密。
S1020，该终端设备根据该第一指示信息，确定与该网络设备建立匿名RRC连接。
应理解，S1020可以参考上述S320的相关描述，为了简洁，在此不再赘述。
还应理解，终端设备确定与该网络设备建立RRC连接后，会进行建立匿名RRC连接的过程，本申请实施例对如何建立匿名RRC连接的过程不做限定，例如可以参考方法200的相关描述。
S1030，该终端设备在该网络设备建立好该匿名RRC连接后，该网络设备向该终端设备发送安全模式命令消息。
该终端设备接收该网络设备发送的该安全模式命令消息。
应理解，该安全模式命令消息为RRC消息，用于激活空口的安全，安全模式命令消息也可以有其他的消息名称。
还应理解，该第一公钥也可以通过S1030中的安全模式命令消息发送给该终端设备。或者，第一公钥也可以通过其他消息发送给终端设备，本申请实施例对第一公钥的发送方式不做限定。
S1040，该终端设备向该网络设备发送安全模式完成(security mode complete)消息。
可选地，该安全模式完成消息中携带终端设备的第二公钥，用于在网络设备给终端设备发送数据或者信令时使用该第二公钥进行加密。
本申请实施例中，对于上行，终端设备可以使用第一公钥对数据或者信令进行加密，并将加密后的数据发送给网络设备，网络设备可以使用自己的私钥进行解密；对于下行，网络设备可以使用第二公钥对数据或者信令进行加密，终端设备可以使用自己的私钥进行解密。
S1050，该终端设备使用第一公钥对第一数据进行加密。
S1060，该终端设备向该网络设备发送该加密后的第一数据。
应理解，这里的第一数据包含需要匿名传输的数据，或者终端设备与网络设备之间的信令。
可选地，终端设备和网络设备之间的信令包括但不限于携带匿名数据的RRC消息。
应理解，考虑到下行信息安全需求低，可以考虑不加密。如果下行也需要加密，则可以在安全模式完成消息中可以将终端设备的第二公钥发送给网络设备。
还应理解，考虑到匿名传输的第一数据是用于运营商网络维护用的，保密的必要性不强，因此一种方法是，对于需要通过匿名方式传输的数据，尤其是针对MDT数据，可以不启用空口的安全机制，例如网络设备可以不向终端设备发送该第一公钥，在建立好该匿名RRC连接后，不对该第一数据进行加密，直接进行该第一数据的传输，或者网络设备指示终端设备是否启用空口的安全机制。
还应理解，在普通的RRC连接建立过程中，网络设备会获取到终端设备的接入能力。为了更好保护终端设备的隐私，另外考虑匿名传输的数据量一般相对较少，可以不需要支持移动性，不需要终端设备进行测量，因此不需要获取终端设备完整的接入能力。用于匿 名传输的接入层能力可以是简化的能力，可以设计独立的“匿名传输的终端设备能力”，比如不包含测量能力，不包含载波聚合能力，包含是否支持非对称密钥机制，以及支持的安全算法等。简化的终端设备接入层可以一定程度上隐藏用户的身份。网络设备可以基于“匿名传输的终端设备能力”对终端设备进行空口的无线配置。
一种可能的实现方式中，“匿名传输的终端设备能力”可以是在终端设备与网络设备建立好匿名RRC连接后，由该终端设备发送给该网络设备，例如，可以是网络设备向该终端设备发送能力请求信息，终端设备向网络设备上报“匿名传输的终端设备能力”；或者，也可以是终端设备主动上报“匿名传输的终端设备能力”。
另一种可能的实现方式中，“匿名传输的终端设备能力”可以是在终端设备与网络设备建立匿名RRC连接的过程中，由该终端设备发送给该网络设备，例如，终端设备可以在RRC连接建立完成消息中携带“匿名传输的终端设备能力”。
应理解，终端设备和网络设备之间的空口安全机制，以及终端设备上报“匿名传输的终端设备能力”同样适用于上述各个方法实施例。
本申请实施例的通信方法，提供了一种匿名通信时的空口保护机制，网络设备可以将网络设备的公钥发送给终端设备，有助于终端设备对需要通过匿名方式传输的数据进行加密保护。
需要说明的是，本申请上述各个方法实施例中，由终端设备实现的方法和步骤，也可以由可用于终端设备的部件(例如芯片或者电路)实现，由网络设备实现的方法和步骤，也可以由可用于网络设备的部件(例如芯片或者电路)实现。
