Description

通信方法、装置及系统
本申请要求于2018年12月20日提交国家知识产权局、申请号为201811562867.0、申请名称为“通信方法、装置及系统”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
本申请涉及通信技术领域，尤其涉及可以支持匿名方式连接的通信方法、装置及系统。
背景技术
为了节省数据收集成本，现有技术中引入自动测量收集(measurement collection)的最小化路测(minimization of drive tests，MDT)技术来完成部分传统的路测工作，以检测和优化无线网络中的问题或故障。其中，MDT技术的应用场景例如可以包括：运营商一般每一个月都要做例行的网络覆盖路测，或者，针对用户投诉也会做一些针对特定区域的网络覆盖路测，等等。
目前，MDT技术的实现有赖于终端设备的上报。根据现有技术，终端设备必须要通过核心网的认证鉴权后才能上报MDT数据给基站，即终端设备先在空口建立无线资源控制(radio resource control，RRC)连接，并且通过核心网的认证或鉴权，空口安全成功激活后才能发送MDT数据给基站。
然而，由于MDT数据中携带有位置信息，涉及安全和用户隐私问题，可能存在准入风险。因此，如何保护MDT数据传输过程中的安全和用户隐私问题，是目前亟待解决的问题。
发明内容
本申请实施例提供的通信方法可以用于保护数据传输过程中的安全和用户隐私问题。
为达到上述目的，本申请的实施例采用如下技术方案：
第一方面，提供了一种通信方法及其相应的通信装置。在该方案中，接入网设备接收来自终端设备的第一消息，该第一消息用于指示该终端设备请求使用匿名方式建立无线资源控制RRC连接；接入网设备根据该第一消息，获知该终端设备请求使用匿名方式建立所述RRC连接；接入网设备确定与该终端设备之间建立匿名方式的RRC连接。考虑到构成用户隐私的要素包含两个方面，即用户隐私的主体和客体，主体一般通过终端设备的身份信息进行表征；客体是私有信息。本申请实施例考虑从主体入手来解决匿名数据的隐私问题。基于该方案，由于接入网设备和终端设备之间可以建立匿名方式的RRC连接，因此可以传输匿名数据，从而可以保护数据传输过程中的安全和用户隐私问题。一种可能的实现方式中，该匿名数据例如可以包括最小化路测MDT数据，从而可以减轻MDT数据传输过程中的安全和用户隐私问题。

可选的，本申请实施例中，与核心网设备建立针对终端设备的连接的步骤例如可以包括基站向核心网设备发送初始终端消息(initial UE message)，以使得核心网设备在接收来自基站的初始终端消息之后，进行终端设备的认证或鉴权，进而，核心网设备向基站发送初始化上下文请求(initial context setup request)，基站向核心网设备回复初始化上下文响应(initial context setup response)等，具体可参考现有的实现方式，在此不再赘述。

考虑到构成用户隐私的要素包含两个方面，即用户隐私的主体和客体，主体一般通过终端设备的身份信息进行表征；客体是私有信息。私有信息如果缺少了主体，则就不再构成隐私问题了。私有信息例如可以包括位置信息。而位置信息对于网络优化 至关重要。例如，如果没有位置信息，MDT效果将大打折扣。既然位置信息很重要，本申请实施例考虑从主体入手来解决匿名数据的隐私问题。基于本申请实施例提供的通信系统，由于接入网设备和终端设备之间可以建立匿名方式的RRC连接，因此可以传输匿名数据，从而可以保护数据传输过程中的安全和用户隐私问题。一种可能的实现方式中，该匿名数据例如可以包括MDT数据，从而可以减轻MDT数据传输过程中的安全和用户隐私问题。

S301、基站向终端设备发送消息a。
相应的，终端设备接收来自基站的消息a。
其中，该消息a包括指示信息1，该指示信息1用于指示用于终端设备请求使用匿名方式建立RRC连接的随机接入的专用资源的配置信息。
可选的，本申请实施例中，指示信息1用于指示用于终端设备请求使用匿名方式建立RRC连接的随机接入的专用资源的配置信息，可以是指，该指示信息1包括用于终端设备请求使用匿名方式建立RRC连接的随机接入的专用资源的配置信息；或者可以是指，该指示信息1包括用于终端设备请求使用匿名方式建立RRC连接的随机接入的专用资源的配置信息的标识(或索引)等，进而，终端设备根据专用资源的配置信息的标识(或索引)、以及专用资源的配置信息与专用资源的配置信息的标识(或索引)的对应关系，可以确定专用资源的配置信息，本申请实施例对此不作具体限定。
示例性的，该消息a例如可以是图3中的系统广播消息。也就是说，基站可以通过系统广播消息广播用于终端设备(这里是一个泛指的终端设备)请求使用匿名方式建立RRC连接的随机接入的专用资源的配置信息。比如，一个系统信息块(system information block，SIB)专门用于广播匿名传输相关的配置，在该SIB中可以包括用于终端设备请求使用匿名方式建立RRC连接的随机接入的专用资源的配置信息。
可选的，该消息a还可以是寻呼消息等其他消息，本申请实施例对此不作具体限定。
本申请实施例中上述步骤S301可以为可选的步骤，终端设备可以基于接收来自基站的消息a获知用于终端设备请求使用匿名方式建立RRC连接的随机接入的专用资源的配置信息。
本申请实施例中也可以不执行步骤S301，而是可以由基站和终端设备预先协商好用于终端设备请求使用匿名方式建立RRC连接的随机接入的专用资源的配置信息；或者，预先配置或者预先约定用于终端设备请求使用匿名方式建立RRC连接的随机接入的专用资源的配置信息，本申请实施例对此不作具体限定。
可选的，本申请实施例中，专用资源的配置信息可以是随机接入前导码信息、随机接入时域资源信息或随机接入频域资源信息的任意组合。
例如，专用资源的配置信息可以包括随机接入前导码信息；或者，专用资源的配置信息可以包括随机接入时域资源信息；或者，专用资源的配置信息可以包括随机接入频域资源信息；或者，专用资源的配置信息可以包括随机接入频域资源上的随机接 入前导码信息，也就是说专用资源的配置信息包括了随机接入频率资源信息和随机接入前导码信息；或者，专用资源的配置信息可以包括随机接入时域资源上的随机接入前导码信息，也就是说专用资源的配置信息包括了随机接入时域资源信息和随机接入前导码信息；或者，专用资源的配置信息可以包括随机接入时域资源和随机接入频域资源上的随机接入前导码，也就是说专用资源的配置信息包括了随机接入时域资源信息、随机接入频率资源信息和随机接入前导码信息。
可选的，本申请实施例中，随机接入时域资源信息例如可以包括随机接入时域资源的标识或者随机接入时域资源的配置，其中，随机接入时域资源的配置例如可以包括帧(frame)、符号(symbol)、时隙(slot)等的配置。

可选的，本申请实施例中，若终端设备的服务小区不支持传输匿名数据或者不支持建立匿名方式的RRC连接，则终端设备可以不传输匿名数据，或者可以按照现有的方式建立RRC连接以及传输匿名数据，本申请实施例对此不作具体限定。
由于移动运营商可以通过接入网设备(例如本申请实施例中的基站)控制在哪些小区传输匿名数据或者建立匿名方式的RRC连接，因此可以降低对系统的影响。比如，移动运营商可以选择在负载低的小区上传输匿名数据，从而减少由于MDT数据传输对于用户业务的影响。
需要说明的是，本申请实施例示例性的以上述指示信息1和上述指示信息2可以是通过一条消息(比如上述消息a)发送给终端设备为例进行说明。当然，上述指示信息1和上述指示信息2也可以是通过不同的消息发送给终端设备，本申请实施例对此不作具体限定。
S302、终端设备确定使用匿名方式建立RRC连接。
可选的，本申请实施例中，确定使用匿名方式建立RRC连接的终端设备可以是针对空闲态的终端设备，在此统一说明，以下不再赘述。
可选的，本申请实施例中，终端设备确定使用匿名方式建立RRC连接可以包括：终端设备根据上述指示信息2，确定使用匿名方式建立RRC连接。比如，终端设备可以在需要传输匿名数据，并且根据上述指示信息2获知终端设备的服务小区支持建立匿名方式的RRC连接或者支持传输匿名数据的情况下，确定使用匿名方式建立RRC连接。
上述指示信息2也可以是可选的，即基站不向终端设备指示终端设备的服务小区是否支持传输匿名数据或者终端设备的服务小区是否支持建立匿名方式的RRC连接，则终端设备也可以在需要传输数据的情况下，确定使用匿名方式建立RRC连接。比如，终端设备可以在需要传输MDT数据的情况下，确定使用匿名方式建立RRC连接。
S303、终端设备向基站发送消息b。
相应的，基站接收来自终端设备的消息b。
其中，该消息b包括终端设备使用的前导码。
其中，该消息b为图1所示的通信系统部分的第一消息的一种可能的形式。
示例性的，该消息b例如可以是图3中的随机接入过程中的消息1(message1)。
可以理解，该消息1是是随机接入过程的第一条消息，也可以称为前导码消息，在此统一说明，以下不再赘述。
以消息b为随机接入过程中的消息1为例进行说明，可选的，本申请实施例中，终端设备可以根据步骤S301中的指示信息1向基站发送消息1。比如，终端设备在消息1中携带的前导码可以为指示信息1指示的专用资源的配置信息中的前导码信息对应的前导码；或者，终端设备可以在指示信息1指示的专用资源的配置信息中的随机接入时域资源信息对应的随机接入时域资源上向基站发送消息1；或者，终端设备可以在指示信息1指示的专用资源的配置信息中的随机接入频域资源信息对应的随机接入频域资源上向基站发送消息1；或者，终端设备可以在指示信息1指示的专用资源的配置信息中的随机接入时域资源信息对应的随机接入时域资源上向基站发送消息1，消息1中包括指示信息1指示的专用资源的配置信息中的前导码信息对应的前导码；或者，终端设备可以在指示信息1指示的专用资源的配置信息中的随机接入频域资源信息对应的随机接入频域资源上向基站发送消息1，消息1中包括指示信息1指示的专用资源的配置信息中的前导码信息对应的前导码；或者，终端设备可以在指示信息1指示的专用资源的配置信息中的随机接入时域资源信息对应的随机接入时域资源和随机接入频域资源信息对应的随机接入频域资源上向基站发送消息1，消息1中包括指示信息1指示的专用资源的配置信息中的前导码信息对应的前导码。
或者，以消息b为随机接入过程中的消息1为例进行说明，可选的，终端设备也可以根据预先协商好、预先配置或者预先约定的资源配置信息向基站发送消息1。比如，终端设备在消息1中携带的前导码可以为预先协商好、预先配置或者预先约定的专用资源的配置信息中的前导码信息对应的前导码；或者，终端设备可以在预先协商好、预先配置或者预先约定的专用资源的配置信息中的随机接入时域资源信息对应的随机接入时域资源上向基站发送消息1；或者，终端设备可以在预先协商好、预先配置或者预先约定的专用资源的配置信息中的随机接入频域资源信息对应的随机接入频域资源上向基站发送消息1；或者，终端设备可以在预先协商好、预先配置或者预先 约定的专用资源的配置信息中的随机接入时域资源信息对应的随机接入时域资源上向基站发送消息1，消息1中包括预先协商好、预先配置或者预先约定的专用资源的配置信息中的前导码信息对应的前导码；或者，终端设备可以在预先协商好、预先配置或者预先约定的专用资源的配置信息中的随机接入频域资源信息对应的随机接入频域资源上向基站发送消息1，消息1中包括预先协商好、预先配置或者预先约定的专用资源的配置信息中的前导码信息对应的前导码；或者，终端设备可以在预先协商好、预先配置或者预先约定的资源配置信息中的随机接入时域资源信息对应的随机接入时域资源和随机接入频域资源信息对应的随机接入频域资源上向基站发送消息1，消息1中包括预先协商好、预先配置或者预先约定的专用资源的配置信息中的前导码信息对应的前导码。
S304、基站根据消息b，确定该终端设备进行随机接入的第一随机接入资源。
其中，第一随机接入资源是用于终端设备(这里是一个泛指的终端设备)请求使用匿名方式建立RRC连接的随机接入的专用资源，包括第一随机接入前导码、第一随机接入时域资源或第一随机接入频域资源的任意组合。
可选的，上述专用资源的配置信息包括第一随机接入资源的配置信息。该第一随机接入资源的配置信息可以是第一随机接入前导码信息、第一随机接入时域资源信息或第一随机接入频域资源信息的任意组合，对应上述第一随机接入资源。示例性的，第一随机接入时域资源信息例如可以包括第一随机接入时域资源的标识或索引或者第一随机接入时域资源的配置，第一随机接入时域资源的配置例如可以包括帧(frame)、符号(symbol)、时隙(slot)等的配置，其中，第一随机接入时域资源信息对应上述第一随机接入时域资源；第一随机接入频域资源信息例如可以包括第一随机接入频域资源的标识或索引或者第一随机接入频域资源的配置，第一随机接入频域资源的配置例如可以包括带宽、资源块等的配置，其中，第一随机接入频域资源信息对应上述第一随机接入频域资源；第一随机接入前导码信息例如可以包括第一随机接入前导码的标识或者第一随机接入前导码的配置，第一随机接入前导码的配置例如可以包括前导码，其中，第一随机接入前导码信息对应上述第一随机接入前导码，本申请实施例对此不作具体限定。
换言之，该第一随机接入资源可以是上述专用资源的配置信息对应的随机接入资源集合中的随机接入资源。其中，该第一随机接入前导码对应上述步骤S303消息1中携带的前导码，该第一随机接入时域资源对应上述步骤S303发送消息1的随机接入时域资源，该第一随机接入频域资源对应上述步骤S303发送消息1的随机接入频域资源，相关描述可参考上述步骤S303，在此不再赘述。
S305、基站根据第一随机接入资源，获知终端设备请求使用匿名方式建立RRC连接。
可选的，本申请实施中，对于步骤上述步骤S303-S305，一种替代的方案是，终端设备向基站发送随机接入过程中的消息b，消息b中携带用于指示终端设备请求使用匿名方式建立RRC连接的信息，进而基站根据该信息，获知终端设备请求使用匿名方式建立RRC连接，本申请实施例对此不作具体限定。
S306、基站向终端设备发送消息c。
相应的，终端设备接收来自基站的消息c。
其中，该消息c包括基站为该终端设备分配的临时小区无线网络临时标识(temp cell radio network temporary identifier，TC-RNTI)。
其中，该消息c是针对上述消息b的响应消息。可选的，如图3所示，在上述消息b为随机接入过程中的消息1的情况下，该消息c例如可以为随机接入响应(random access response，RAR)消息。
其中，该TC-RNTI在随机接入完成后变成终端设备的小区无线网络临时标识(cell radio network temporary identifier，C-RNTI)，后续基站和终端设备基于该C-RNTI进行匿名数据传输。由于该C-RNTI是在基站不知道用户身份的情况下分配给终端设备的，因此后续即使基站与终端设备基于该C-RNTI进行通信，也不存在隐私的问题。
S307、终端设备向基站发送消息d。
相应的，基站接收来自终端设备的消息d。
示例性的，该消息d例如可以是图3中的RRC建立请求(RRC setup request)消息。
在现有技术中，如果终端设备在核心网进行了注册，则核心网会给该终端设备分配一个非接入层的终端标识，可以标识所述终端。比如S-TMSI或者5G S-TMSI等，在RRC建立请求中会携带这个非接入层的终端标识或该终端标识的部分字段或者包含该终端标识的标识信息(例如扩展的标识)；如果终端设备未在核心网进行注册，则在RRC建立完成(RRC setup complete)消息中会携带注册的核心网标识。与现有技术不一样，可选的，由于本申请实施例要实现匿名数据传输，因此本申请实施例中，无论核心网设备是否给终端设备分配了终端标识，比如S-TMSI或者5G S-TMSI，该消息d均不会携带该非接入层的终端标识或该终端标识的部分字段或者包含该终端标识的标识信息(例如扩展的标识)，而是携带终端设备自己产生或决定的一个值，比如随机值，该随机值用于终端设备进行随机接入的竞争解决。比如，基站获取该随机值之后，可以在消息d的响应消息(图3中未示出，例如可以是竞争冲突解决消息)中返回该随机值。进而终端设备根据基站返回的随机值是否是自己发送的来确定是否自己竞争成功。其中，若基站返回的随机值是自己发送的，即可视为成功，否则视为竞争失败。
可选地，一个终端设备可能多次建立匿名方式的RRC连接来上报匿名数据，为了使得系统能够将将这个终端设备多次上报的匿名数据关联到一个终端设备上，一种可能的实现方式是，终端设备自己产生或决定了一个值(比如随机值)后，后续匿名方式的RRC连接也使用这个值，从而能将一个终端设备多次上报的匿名数据关联在一起。
其中，步骤S307中的消息d可以通过步骤S306中的TC-RNTI进行加扰，相关实现可参考现有的实现方式，在此不再赘述。
S308、基站向终端设备发送消息e。
相应的，终端设备接收来自基站的消息e。
示例性的，该消息e例如可以是图3中的RRC建立(RRC setup)消息。
需要说明的是，本申请实施例中，以终端设备为随机接入竞争成功的终端设备为例进行说明。其中，若终端设备竞争失败，则不会执行后续流程，在此统一说明，以 下不再赘述。
S309、终端设备向基站发送消息f。
相应的，基站接收来自终端设备的消息f。
示例性的，该消息f例如可以是图3中的RRC建立完成消息。
可选的，由于本申请实施例希望实现匿名数据传输，因此本申请实施例中，无论终端设备是否在核心网进行了注册，该消息f均不携带终端设备在核心网注册的信息，比如不携带注册的核心网标识。
或者，可选的，由于本申请实施例希望实现匿名数据传输，因此本申请实施例中，无论终端设备是否在核心网进行了注册，消息f均不携带非接入层(non-access stratum，NAS)协议数据单元(protocol data unit，PDU)信元，或者消息f携带长度为0的NAS PDU信元，其中，该NAS PDU信元是基站和核心网设备进行交互的信令。
由于消息f不携带终端设备在核心网注册的信息，或者消息f不携带NAS PDU信元，或者消息f携带长度为0的NAS PDU信元，因此不仅可以减少信令开销，并且可以更好的隐藏用户信息。
S310、基站确定与终端设备之间建立匿名方式的RRC连接。
一种可能的实现方式中，基站确定与终端设备之间建立匿名方式的RRC连接，包括：基站不执行与核心网设备建立针对终端设备的连接的步骤。
其中，本申请实施例中，基站与核心网设备之间针对终端设备的连接例如可以是新空口(new radio，NR)系统中针对该终端设备的N2连接或下一代(next generation)NG连接(即UE-associated logical NG-connection)；或者，基站与核心网设备之间针对终端设备的连接例如可以是LTE系统中针对该终端设备的S1连接等，本申请实施例对此不作具体限定。
其中，与核心网设备建立针对终端设备的连接的步骤例如可以包括基站向核心网设备发送初始终端消息(initial UE message)，以使得核心网设备在接收来自基站的初始终端消息之后，进行终端设备的认证或鉴权，进而，核心网设备向基站发送初始化上下文请求(initial context setup request)，基站向核心网设备回复初始化上下文响应(initial context setup response)等，具体可参考现有的实现方式，在此不再赘述。
其中，本申请实施例中，基站不执行与核心网设备建立针对终端设备的连接的步骤，可以是指在匿名方式下，基站与终端设备之间完成连接建立，无需引入核心网设备的参与；或者是指，基站跳过与核心网设备建立针对终端设备的连接的步骤；或者是指，基站忽略与核心网设备建立针对终端设备的连接的步骤；或者是指，基站不发起与核心网设备建立针对终端设备的连接的步骤等，本申请实施例对此不作具体限定。
也就是说，本申请实施例中，基站在获知终端设备请求使用匿名方式建立RRC连接之后，不需要与核心网设备建立针对终端设备的连接。
另一种可能的实现方式中，基站确定与终端设备之间建立匿名方式的RRC连接，包括：基站建立针对终端设备的与核心网设备连接，但是终端设备不向核心网设备发送能直接或间接识别该终端设备的身份信息，比如IMSI,SUPI，S-TMSI或5G-TMSI等，本申请实施例对此不作具体限定。
在基站确定与终端设备之间建立匿名方式的RRC连接之后，基站和终端设备之间可以进行空口的匿名传输而无需识别用户身份。下面示例性的提供两种匿名传输方式。
可选的，一种可能的实现方式中，可以通过控制面传输匿名数据。比如，如图3所示，本申请实施例提供的通信方法还可以包括如下步骤S311：
S311、终端设备向基站发送消息g。
相应的，基站接收来自终端设备的消息g。
其中，该消息g携带匿名数据。即，匿名数据通过信令承载进行传输。
其中，该消息g可以为本申请实施例中第二消息的一种可能的形式。
示例性的，该消息g例如可以是图3中的RRC消息。可选的，该RRC消息可以是一个用于传输匿名数据的专用RRC消息。比如，该RRC消息可以为匿名数据传输(anonymous data transfer)消息。
可选的，本申请实施例中的匿名数据可以包括MDT数据或者其他需要匿名传输的数据等，在此统一说明，以下不再赘述。
可选的，本申请实施例中，匿名数据作为RRC消息中的信元，可以是一个对RRC层透明的字节流，也可以是具体的匿名传输的数据结构(比如，MDT数据结构)。
示例性的，字节流的结构示意如下：
Figure PCTCN2019125728-appb-000001
需要说明的是，本申请实施例中，对RRC层透明的字节流，是指从RRC层来看就是一个字节流，RRC层不解码字节流，即RRC层不知道字节流内容的含义，在此统一说明，以下不再赘述。
本申请实施例对具体的匿名传输的数据结构(比如，MDT数据结构)不作具体限定。
可选的，本申请实施例中，基站接收到来自终端设备的消息g之后，从消息g中获取匿名数据，进而可以将匿名数据递交给其他协议层或者操作管理维护(operation administration and maintenance，OAM)系统等。其中，其他协议层例如可以是MDT协议层，本申请实施例对此不作具体限定。
需要说明的是，本申请实施例中的消息g可以是一条或者多条消息，具体取决于匿名数据的大小，在此统一说明，以下不再赘述。
可选的，另一种可能的实现方式中，可以通过用户面传输匿名数据。比如，如图3所示，本申请实施例提供的通信方法还可以包括如下步骤S312-S315：
S312、基站向终端设备发送消息h。
相应的，终端设备接收来自基站的消息h。
其中，该消息h用于指示建立数据承载(data radio bearer，DRB)。
其中，该消息h可以为本申请实施例中第三消息的一种可能的形式。
示例性的，该消息h例如可以是图3中的RRC重配置(RRC reconfiguration)消息。
可选的，本申请实施例中，该消息h用于指示建立DRB例如可以是该消息h中包括用于指示建立DRB的信息，或者该消息h本身具备指示建立DRB的功能，本申请实施例对此不作具体限定。
可选的，本申请实施例中，为了与普通的DRB进行区分，该消息h中还可以包括用于指示该DRB是用于匿名数据传输的信息。可以理解的是，对于匿名数据是MDT数据的场景，用于指示该DRB是用于匿名数据传输的信息具体可以为用于指示该DRB是用于MDT数据传输的信息。
可选的，本申请实施例中，可以引入承载类型信息或者MDT承载类型来指示本次的数据传输是MDT数据的传输，在此统一说明，以下不再赘述。
此外，不同于传统的DRB，该DRB没有服务质量(quality of service，QoS)流标识与该DRB的映射关系等配置，在此统一说明，以下不再赘述。
S313、终端设备根据用于指示建立DRB的信息，建立相应的DRB。
具体的建立DRB的方式可参考现有技术，在此不再赘述。
S314、终端设备向基站发送消息i。
相应的，基站接收来自终端设备的消息i。其中，该消息i用于指示DRB建立完成。
示例性的，该消息i例如可以是图3中的RRC重配置完成(RRC reconfiguration complete)消息。
S315、终端设备在DRB上向基站发送匿名数据。
相应的，基站从DRB上接收来自终端设备的匿名数据。
其中，不同于普通DRB将数据发送给核心网的用户面，比如服务网关。可选的，本申请实施例中，基站从DRB上接收来自终端设备的匿名数据之后，可以将匿名数据递交给其他协议层或者OAM系统等。其他协议层例如可以是MDT协议层，本申请实施例对此不作具体限定。
需要说明的是，本申请实施例中，步骤S314与步骤S315之间没有必然的执行先后顺序，可以是先执行步骤S314，再执行步骤S315；也可以是先执行步骤S315，再执行步骤S314；还可以是同时执行步骤S314和S315，本申请实施例对此不作具体限定。
通过上述步骤S311，或者上述步骤S312-S315，均可以实现匿名数据传输。其中，通过控制面传输匿名数据的方式，由于不需要建立DRB，因此相比于通过用户面传输匿名数据的方式，更加简单；通过用户面传输匿名数据的方式，由于匿名数据不需要进行RRC消息的解码，因此相比于通过控制面传输匿名数据的方式，减少了基站的处理资源开销。
考虑到在传统的数据传输中，终端设备的接入层(例如可以是RRC层)并不知道数据传输是否完成，因此由基站来释放RRC连接。但是对于匿名数据，例如MDT数据，由于匿名数据是接入层产生的，因此接入层知道匿名数据是否传输完成。因此，可选的，本申请实施例中，在数据传输完成后或者传输最后一个匿名数据包时，由终端设备知会基站匿名数据传输完成或者请求基站释放终端设备对应的RRC连接，从而能及时释放终端设备对应的RRC连接，节省终端设备的能耗。例如，可以有以下几种方法：
