Description

通信方法、装置及系统
本申请要求于2019年03月29日提交中国专利局、申请号为201910252652.7、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
本申请实施例涉及通信技术领域，尤其涉及一种通信方法、装置及系统。
背景技术
移动网络运营商需要对网络设备覆盖范围内的移动网络质量进行评估，评估包括识别覆盖强弱、覆盖漏洞等，因此，提出了最小化路测(Minimization of Drive Tests，MDT)。其中，MDT的方式是指：一些特定的终端设备进行MDT测量或记录，然后向网络设备上报测量结果或日志(log)记录或一些事件的记录，上报的内容包括：无线接入网(Radio Access Network，RAN)的信号质量测量方面以及服务质量(Quality of Service，QoS)相关的数据，然后网络设备或其他设备根据终端设备上报的日志记录进行移动网络质量评估。或者网络设备根据网络设备或其他设备对某些终端设备的上报测量结果进行移动网络质量评估。终端设备上报的测量结果或日志记录或一些事件的记录可以是终端在如下情况下获得，一种情况为：终端设备在空闲(idle)态或者非激活态(inactive)(非激活态也称为去激活态)时，根据从网络设备接收到的测量配置，进行MDT日志测量以获得上报的日志记录，这种方式称为记录MDT(logged MDT)。对于logged MDT而言，终端设备一般在一个网络配置的持续时间内进行周期间隔记录测量的结果，即周期性进行日志记录。该周期间隔一般也是由网络设备配置的。一种情况为：终端设备在连接态时，网络设备配置终端设备进行一些进行测量，比如网络的下行信号质量测量等，终端设备在连接态上报对应的测量结果，这种方式称为立即MDT(immediate MDT)。另外一种情况是：如果发生无线链路失败(Radio Link Failure，RLF)或者其他一些失败事件(比如终端发起无线资源控制(radio resource control，RRC)连接失败等)，则终端设备记录这些事件并进行上报。
对于logged MDT，终端设备在空闲态或非激活态时，会根据接收到的logged MDT测量配置进行logged MDT测量，获得日志记录，然后终端设备从空闲态或非激活态进入连接态时，终端设备会将日志记录发送给基站。其中，向终端设备发送logged MDT测量配置的基站与接收终端设备发送的日志记录的基站可能不是同一基站。
随着移动通信系统的演进，目前一个终端设备可能与多个基站通信，即双连接(dual-connectivity，DC)，也称为多连接(multi-radio dual connectivity，MR-DC)，该多个基站中包括主基站和辅基站。这多个基站可能是属于同一无线接入技术(radio  access technology,RAT)的基站，也可以是不同RAT的基站。因此，现有技术中若终端在第一RAT的空闲态下进行logged MDT测量并获得日志记录，当终端设备重选到第二RAT的基站的小区时，终端停止测量。当终端设备在第二RAT的基站小区建立RRC连接并且网络侧还为终端设备配置了MR-DC(例如主基站为第二RAT，辅基站为第一RAT)时，辅基站的RAT与终端进行logged MDT测量时的空闲态或非激活态对应的RAT相同。这种情况下，该logged MDT测量生成的日志记录应该如何处理，是一个亟待解决的问题。

图1为本申请实施例提供的通信系统的示意图，如图1所示，通信系统包括网络设备和终端设备。
以下，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解：
网络设备：又称为无线接入网(Radio Access Network，RAN)设备，是一种将终端设备接入到无线网络的设备，可以是长期演进(Long Term Evolution，LTE)中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者中继站或接入点，或者5G网络中的基站，如发送和接收点(Transmission and Reception Point，TRP)、控制器，在此并不限定。一种可能的方式中，接入网设备可以是CU和DU分离架构的基站(如 gNB)，如图2所示，图2为本申请一实施例提供的网络设备的协议栈示意图。RAN设备可以与核心网设备相连(例如可以是LTE的核心网，也可以是5G的核心网等)。CU和DU可以理解为是对基站从逻辑功能角度的划分。CU和DU在物理上可以是分离的也可以部署在一起。多个DU可以共用一个CU。一个DU也可以连接多个CU(图中未示出)。CU和DU之间可以通过接口相连，例如可以是F1接口。CU和DU可以根据无线网络的协议层划分。例如无线资源控制(Radio Resource Control，RRC)、业务数据适配协议栈(Service Data Adaptation Protocol，SDAP)以及分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能设置在CU，而无线链路控制(radio link control，RLC)，媒体接入控制(Media Access Control，MAC)层，物理(physical，PHY)层等的功能设置在DU。可以理解对CU和DU处理功能按照这种协议层的划分仅仅是一种举例，也可以按照其他的方式进行划分。例如可以将CU或者DU划分为具有更多协议层的功能。例如，CU或DU还可以划分为具有协议层的部分处理功能。在一种设计中，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。在另一种设计中，还可以按照业务类型或者其他系统需求对CU或者DU的功能进行划分。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。在另一种设计中，CU也可以具有核心网的一个或多个功能。一个或者多个CU可以集中设置，也分离设置。例如CU可以设置在网络侧方便集中管理。DU可以具有多个射频功能，也可以将射频功能拉远设置。
CU的功能可以由一个实体来实现也可以由不同的实体实现。例如，可以对CU的功能进行进一步切分，例如，将控制面(CP)和用户面(UP)分离，即CU的控制面(CU-CP)和CU用户面(CU-UP)。例如，CU-CP和CU-UP可以由不同的功能实体来实现，所述CU-CP和CU-UP可以与DU相耦合，共同完成基站的功能。一种可能的方式中，CU-CP负责控制面功能，主要包含RRC和PDCP-C。PDCP-C主要负责控制面数据的加解密，完整性保护，数据传输等。CU-UP负责用户面功能，主要包含SDAP和PDCP-U。其中SDAP主要负责将核心网的数据进行处理并将数据流(flow)映射到承载。PDCP-U主要负责数据面的加解密，完整性保护，头压缩，序列号维护，数据传输等。其中CU-CP和CU-UP通过E1接口连接。CU-CP代表gNB通过Ng接口和核心网连接。通过F1-C(控制面)和DU连接。CU-UP通过F1-U(用户面)和DU连接。当然还有一种可能的实现是PDCP-C也在CU-UP。
终端设备：可以是无线终端设备也可以是有线终端设备，无线终端设备可以是指一种具有无线收发功能的设备，可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端、增强现实(Augmented Reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等，在此不作限定。可以理解的是，本申请 实施例中，终端设备也可以称为用户设备(user equipment，UE)。
本申请下述各实施例可以应用于多连接MR-DC场景中，但并不限于此。
MR-DC：终端设备与两个或者两个以上网络设备有连接，这两个或者两个以上网络设备可能使用不同的无线载波。可选地这两个或两个以上的网络设备可能为该终端设备提供不同的RLC实体、MAC实体以及PHY实体，即这些网络设备都为该终端设备提供RLC实体、MAC实体以及PHY实体。其中MR-DC中的一种架构中，业务数据流从一个网络设备的PDCP层映射到一个或多个网络设备的RLC、MAC以及PHY层，即具有相同的PDCP层实体；其中MR-DC中的另外一种架构中，业务数据流从核心网(Core Network，CN)中分流，分别映射到不同网络设备的PDCP实体、RLC实体、MAC实体和PHY实体。可以理解的是，本申请实施例中，MR-DC中的所述两个或者两个以上网络设备使用的无线载波可能采用相同的通信制式，也可能采用不同的通信制式。比如可能一部分载波采用LTE无线接入通信制式与终端设备通信，一部分载波采用5G新无线(New Radio,NR)无线接入通信制式与终端设备通信。
其中，MR-DC场景中，两个或多个网络设备中，其中一个称为主基站(master node)，其他称为辅基站(secondary node)。需要说明的是，MR-DC是指针对某个终端设备来说的。主基站可以为该终端设备提供和核心网之间控制面连接。辅基站可以不为该终端设备提供和核心网之间控制面连接。
终端设备可以和主基站和辅基站进行通信。MR-DC又可以包括：EN-DC、NGEN-DC、NE-DC、NR-DC。
EN-DC中主基站为连接到4G核心网的LTE基站(例如eNB)，辅基站为NR基站(例如gNB)。
NGEN-DC中主基站为连接5G核心网的LTE基站，辅基站为NR基站。
NE-DC中主基站为连接到5G核心网的NR基站，辅基站为LTE基站。
NR-DC中主基站为连接到5G核心网5的NR基站，辅基站为NR基站。
MR-DC中，辅基站下的服务小区称为辅小区组(Secondary Cell Group，SCG)，该辅小区组由主辅小区和可选的一个或多个辅小区组成。主基站下的小区称为主小区组(master cell group,MCG),该主小区组由主小区和可选的一个或多个辅小区组成。需要说明的是，MR-DC中主基站和辅基站可以是前面所述网络设备的各种形式和结构。可选地，可能主基站和辅基站使用相同的CU而DU不同，或使用相同的DU而CU不同。
下面对无线网络的各协议层进行解释说明。
RRC层：用于执行广播、寻呼、RRC连接建立、无线承载控制、移动性管理、终端测量上报控制等。
PDCP层：可执行诸如安全性、头压缩、加密之类的服务，PDCP层可以对应多个PDCP实体，每个PDCP实体承载一个无线承载(Radio Bear，RB)的数据。
RLC层：执行诸如分段、重新装配、重传等服务，RLC层可以对应多个RLC实体，每个RLC实体为对应的PDCP实体提供服务。
MAC层：对逻辑信道上的业务提供数据传输服务，执行诸如调度、混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)的确认和否定服务。
PHY层：对从MAC层传下来的数据进行编码和传输。
在MR-DC中，某些无线承载的PDCP层、RLC层、MAC层、PHY层可能位于不同的基站。
可以理解的，本申请实施例中，终端设备和/或网络设备可以执行本申请实施例中的部分或全部步骤，这些步骤或操作仅是示例，本申请实施例还可以执行其它操作或者各种操作的变形。此外，各个步骤可以按照本申请实施例呈现的不同的顺序来执行，并且有可能并非要执行本申请实施例中的全部操作。
图3为本申请一实施例提供的通信方法的流程图，如图3所示，本实施例的方法可以包括：
S301、第一网络设备确定第一信息。
S302、第一网络设备向终端设备发送第一信息。相应地，终端设备接收第一网络设备发送的第一信息。
S301’、第二网络设备获取第一信息。
S302’、第二网络设备向终端设备发送第一信息。相应地，终端设备从第二网络设备接收第一信息。
S303、终端设备根据所述第一信息确定终端设备可向所述第一网络设备发送MDT信息。
本实施例中，第一网络设备例如可以为辅基站，第二网络设备例如为主基站。可选地，第一网络设备对应的通信制式与第二网络设备对应的通信制式不同。
需要说明的是，S302中的第一信息和S302’中的第一信息可以相同，也可以不同。S301的第一信息和S301’中的第一信息可以相同，也可以不同。
在一种可能的实现方式中，本实施例的方法可以包括：S301、S302和S303。第一网络设备确定第一信息，该第一信息与终端设备可向第一网络设备发送MDT信息的确定有关，然后向终端设备发送该第一信息。相应地，终端设备接收第一网络设备发送的第一信息，然后根据所述第一信息确定终端设备可向所述第一网络设备发送MDT信息。可选地，该MDT信息对应的通信制式与该第一网络设备对应的通信制式相同。可选地，该MDT信息对应的通信制式是指终端设备接收要求终端设备进行MDT测量或上报时所用的通信制式，或者为该MDT信息中包含的通信制式。可选地，上述第一网络设备向终端设备发送第一信息的一种可能的实现方式为：第一网络设备通过第二网络设备向终端设备发送第一信息，即第一网络设备向第二网络设备发送第一信息，然后第二网络设备向终端设备发送该第一信息，可选地，第二网络设备可以向终端设备透传该第一信息(比如第一信息携带在第一网络设备为终端设备生成的RRC连接重配消息中，第二网络设备再在为终端设备生成的RRC连接重配消息中携带第一网络设备生成的RRC连接重配消息)，也可以是第二网络设备获取第一信息的内容再向终端设备转发该第一信息(比如在第二网络设备在为终端设备生成的RRC连接重配消息中显示携带第一信息)。上述第一网络设备向终端设备发送第一信息的一种可能的实现方式为：第一网络设备无需通过第二网络设备向终端设备发送第一信息，例如第一网络设备直接向终端设备发送第一信息。
在另一种可能的实现方式中，本实施例的方法可以包括：S301’、S302’和S303。 第二网络设备获取第一信息，该第一信息与终端设备可向第一网络设备发送MDT信息的确定有关，然后向终端设备发送该第一信息。相应地，终端设备从第二网络设备接收第一信息，然后根据所述第一信息确定终端设备可向所述第一网络设备发送MDT信息。可选地，该MDT信息对应的通信制式与该第一网络设备对应的通信制式相同。可选地，该MDT信息对应的通信制式是指终端设备接收要求终端设备进行MDT测量或上报时所用的通信制式，或者为该MDT信息中包含的通信制式。可选地，第二网络设备获取第一信息的一种可能的实现方式为：第二网络设备从第一网络设备接收第一信息。第二网络设备获取第一信息的另一种可能的实现方式为：第二网络设备确定第一信息。
可选地，若终端设备从第一网络设备或第二网络设备接收第一信息后，根据第一信息确定终端设备可向第一网络设备发送MDT信息，则终端设备向第一网络设备发送MDT信息。可选地，终端设备在向第一网络设备发送MDT信息之前，接收第一网络设备发送的MDT信息请求，并根据该MDT信息请求，向第一网络设备发送MDT信息。可选地，终端设备在接收第一网络设备发送的MDT信息请求之前，还向第一网络设备发送一信息，该信息用于指示该终端设备具有需发送给第一网络设备的MDT信息。可选地，若终端设备根据第一信息确定终端设备不可向第一网络设备发送MDT信息，则终端设备不向第一网络设备发送MDT信息，避免MDT信息的泄露。可选地，终端设备发送MDT信息时，终端设备可以直接向第一网络设备发送，还可以先向第二网络设备发送，再由第二网络设备发送给第一网络设备。
可选地，上述的MDT信息包括所述终端设备处于空闲态或非激活态时执行MDT日志测量所记录的信息。可选地，上述的MDT信息包括所述终端设备处于连接态时记录的失败信息，比如RLF信息。可选地，上述的MDT信息还可以包括终端发起RRC连接建立时的失败信息。
本实施例提供的通信方法，终端设备从第一网络设备或第二网络设备接收第一信息，并根据所述第一信息确定终端设备可向所述第一网络设备发送MDT信息。当终端设备可向第一网络设备MDT信息时，终端设备再向第一网络设备发送MDT信息，避免了终端设备获得MDT信息之后就将该MDT信息发送给第一网络设备，避免了网络覆盖情况的泄露，有效且安全的利用了MDT信息。
在一些实施例中，终端设备还向第二网络设备发送第二信息，所述第二信息用于指示所述终端设备具有与所述第二网络设备对应通信制式不同的通信制式的MDT信息。相应地，第二网络设备从终端设备接收第二信息，根据第二信息，确定终端设备可能向其它网络设备(例如第一网络设备)发送MDT信息，所以第二网络设备可以确定不向该终端设备发送MDT测量配置信息，直到所述终端设备不具有与所述第二网络设备对应通信制式不同的通信制式的MDT信息，也就是第二网络设备暂时不向终端设备发送MDT测量配置信息。由于终端设备接收到第二网络设备发送的MDT测量配置信息后，终端设备会删除与所述第二网络设备对应通信制式不同的通信制式的MDT信息，因此本实施例通过上述方案避免了终端设备还未向第一网络设备发送与所述第二网络设备对应通信制式不同的通信制式的MDT信息之前，终端设备就清除了该MDT信息，保证终端设备可以及时将该MDT信息发送给第一网络设备。需要说明 的是，本实施例可以独立于上述实施例实施，也可以与上述实施例结合来实施。
可选地，终端设备向第二网络设备发送第二信息可以是在上述S303之后执行。或者，终端设备向第二网络设备发送第二信息可以是在S302’或S301之前执行，终端设备向第二网络设备发送第二信息后，第二网络设备确定终端设备具有与所述第二网络设备对应通信制式不同的通信制式的MDT信息，然后第二网络设备再向终端设备发送第一信息，否则第二网络设备不向终端设备发送第一信息，避免信令传输资源的浪费。
若终端设备向第二网络设备发送第二信息在S301之前执行，第二网络设备还可以通知第一网络设备：终端设备具有第一网络设备对应通信制式的MDT信息，以便第一网络设备获知终端设备具有第一网络设备对应通信制式的MDT信息，从而确定可向终端设备发送第一信息，然后第一网络设备再向终端设备发送第一信息，否则第一网络设备不向终端设备发送第一信息，避免信令传输资源的浪费。
可选地，终端设备还向第二网络设备发送第三信息，所述第三信息用于指示所述终端设备不具有与所述第二网络设备对应通信制式不同的通信制式的MDT信息。
在一种实现方式中，该终端设备向第二网络设备发送第三信息可以是在终端设备向第二网络设备发送第二信息之后执行，第二网络设备接收到第二信息之后再接收到第三信息，根据该第三信息，可以确定终端设备已将与所述第二网络设备对应通信制式不同的通信制式的MDT信息向其它网络设备发送完毕。可选地，第二网络设备可以根据第三信息，向终端设备发送MDT测量配置信息，保证终端设备可以及时根据第二网络设备的MDT测量配置信息，进行MDT测量。
在一些实施例中，终端设备还从第三网络设备接收所述MDT信息对应的MDT测量配置信息。该第三网络设备可以是与第一网络设备及第二网络设备不同的网络设备，也可以是与第一网络设备相同的网络设备，或者，也可以是与第二网络设备相同的网络设备。例如：终端设备是在从第一网络设备或第二网络设备接收第一信息之前，还接收第三网络设备发送的MDT测量配置信息，然后根据该MDT测量配置信息获得上述MDT信息，然后终端设备再接收上述的第一信息。
在一些实施例中，上述的第一信息与第二PLMN集合与第一PLMN集合具有相同的PLMN的确定有关；第一PLMN集合包括至少一个服务小区对应的PLMN，所述至少一个服务小区为所述终端设备在所述第一网络设备下的至少一个服务小区，该至少一个服务小区对应的PLMN可以是该至少一服务小区中全部或部分对应的PLMN，或者，该至少一个服务小区对应的部分或全部PLMN。一个服务小区可以对应一个或多个PLMN。该第一PLMN集合可以包括一个PLMN或多个PLMN。

下面各实施例以第一网络设备为辅基站，第二网络设备为主基站为例进行描述，但并不限于此。可选地，辅基站对应的通信制式与主基站对应的通信制式不同。终端设备的第二PLMN集合包括终端设备至少一个PLMN，所述至少一个PLMN用于所述终端设备MDT日志上报和/或在空闲态和/或非激活态所执行的MDT日志测量。辅基站的第一PLMN集合包括至少一个服务小区对应的PLMN，该至少一个服务小区为所 述终端设备在所述辅基站下的至少一个服务小区。
可选地，第二PLMN集合可以是终端设备从第三网络设备接收到的MDT测量配置信息中包括的PLMN集合。可选的，该第三网络设备可以是与第一网络设备和第二网络设备不同的网络设备，也可以是与第一网络设备相同的网络设备，或者，也可以是与第二网络设备相同的网络设备。MDT测量配置信息为对应于所述MDT信息的配置信息，该MDT测量配置信息中的PLMN列表代表的是当终端设备的RPLMN属于该PLMN集合内才执行MDT测量记录，或/和当终端设备的当前使用的PLMN和该PLMN集合有至少一个相同的PLMN时才执行MDT记录测量记录，或/和当终端设备的RPLMN属于该PLMN集合内才执行MDT记录上报，或/和当终端设备的当前使用的PLMN和该PLMN集合有至少一个相同的PLMN时才执行MDT记录上报。可选地，第二PLMN集合还可以是从第三网络设备接收到的MDT测量配置信息中包括的PLMN集合和终端设备接收到该MDT测量配置信息时的RPLMN。其中，MDT测量配置信息为对应于所述MDT信息的配置信息。可选地，当终端设备从第三网络设备接收到的所述MDT测量配置信息中不包括PLMN集合时，终端设备把接收到该MDT配置信息时的RPLMN作为第二PLMN集合。

本实施例中，主基站确定终端设备的第二PLMN集合与辅基站的第一PLMN集合是否具有相同的PLMN，若终端设备的第二PLMN集合与辅基站的第一PLMN集合具有相同的PLMN，则主基站确定第三指示信息，该第三指示信息用于指示终端设备可向辅基站发送MDT信息，然后主基站向终端设备发送第三指示信息。可选地，若终端设备的第二PLMN集合与辅基站的第一PLMN集合不具有相同的PLMN，则主基站确定第三指示信息并向终端设备发送第三指示信息，此时该第三指示信息用于指示终端设备不可向辅基站发送MDT信息；或者，若终端设备的第二PLMN集合与辅基站的第一PLMN集合不具有相同的PLMN，则主基站不向终端设备发送第三指示信息。
可选地，终端设备的第二PLMN集合与辅基站的第一PLMN集合具有的相同的PLMN为终端设备的RPLMN。
可选地，主基站还接收终端设备发送的终端设备的第二PLMN集合。
在另一实施方式中，在执行S901之后执行S902’和S903。其中，S903见后续描述。
S902’、主基站确定RPLMN是否包括在第一PLMN集合内。若主基站确定RPLMN包括在第一PLMN集合内，则主基站向终端设备发送第三指示信息。相应地，终端设备接收主基站发送的第三指示信息。
本实施例中，主基站确定终端设备的RPLMN是否包括在辅基站的第一PLMN集合内，若终端设备的RPLMN包括在辅基站的第一PLMN集合内，则主基站确定第三指示信息，该第三指示信息用于指示终端设备可向辅基站发送MDT信息，然后主基站向终端设备发送第三指示信息。可选地，若终端设备的RPLMN不包括在辅基站的第一PLMN集合内，则主基站确定第三指示信息并向终端设备发送第三指示信息，此时该第三指示信息用于指示终端设备不可向辅基站发送MDT信息；或者，若终端设备的RPLMN不包括在辅基站的第一PLMN集合内，则主基站不向终端设备发送第三指示信息。
可选地，主基站还从终端设备接收终端设备的RPLMN。
其中，主基站向终端设备发送第三指示信息，例如可以为：辅基站可以直接向终端设备发送第三指示信息，或者，辅基站可以通过主基站向终端设备发送第三指示信息。
可选地，第三指示信息可以包括在主基站向终端设备发送的RRC连接重配消息。
S903、当第三指示信息用于指示终端设备可向辅基站发送MDT信息时，终端设备根据第三指示信息，向辅基站发送MDT信息。
本实施例中，S903的具体实现过程可以参见图8所示实施例中的相关描述，此处不再赘述。
因此，通过上述方案，终端设备从主基站接收第三指示信息，若第三指示信息指示终端设备可向辅基站发送MDT信息，则终端设备才向辅基站发送MDT信息，避免MDT信息的泄露，有效且安全的利用了MDT信息，第三指示信息与第一PLMN集合相比，减少了终端设备与主基站之间的信令开销。
需要说明的是，图4所示实施例中有关终端设备发送第二信息的方案或者终端设备发送的第三信息的方案，同样适用于图5-图9任一所示实施例中。
在另外一些实施例中，提供了一种通信方法(该方法可以独立于上述各实施例中的方法来实施，也可以与上述任一实施例中的方法结合实施)：终端设备在确定辅基站的信号质量不满足预设通信条件时，确定辅小区组(Secondary Cell Group，SCG)失败，终端设备向主基站发送失败信息，该失败信息例如为：辅小区组失败信息(SCG failure information)。该失败信息可以包括：辅基站的上行指示信息(比如上行随机接入过程失败或上行RLC传输达到最大传输次数等)。
和/或，终端设备在确定主基站的信号质量不满足预设通信条件时，确定主小区组(Master Cell Group，MCG)失败，终端设备向主基站发送失败信息，该失败信息例如为：主小区组失败信息(MCG failure information)。该失败信息可以包括：主基站的上行指示信息(比如上行随机接入过程失败或上行RLC传输达到最大传输次数等等)。可选地，终端设备将失败信息通过终端设备与辅基站之间的RRC连接(比如split SRB或SRB3，split SRB是指主基站和终端设备之间的信令无线承载在主小区组和辅小区组中都存在RLC。SRB3是指辅基站和终端设备之间直接的信令无线承载)发送给辅基站，辅基站接收到失败信息后再将该失败信息发送给主基站。
可选地，上述SCG failure information、MCG failure information可能也是由下行覆盖原因导致的，因此上述SCG failure information、MCG failure information也可以包括一些下行指示信息(比如下行物理信道问题，比如下行失步达到一定次数)。
另外，对于主基站或辅基站上的载波聚合复制功能(即一些数据包进行复制多份，分别在一个基站的多个载波的小区与终端设备通信)，当终端设备检测到该基站的辅服务小区上的载波聚合复制(即只在辅服务小区间进行复制)中上行RLC传输出现问题时(比如上行RLC层的数据传输达到了最大重传次数)，UE会上报失败信息(比如failure information，来指示上行RLC层出现了问题)。如果是主基站中的载波聚合复制中上行RLC传输出现问题，则终端设备把失败信息发送给主基站，如果是辅基站中的载波聚合复制中上行RLC传输出现问题，则终端设备把失败信息发送给辅基站，可选的，终端设备可能直接把失败信息发送给辅基站，也可能是先发送给主基站，然 后主基站再转发给辅基站。
可选地，失败信息中可以包括终端设备的位置信息和/或时间信息，该位置信息例如为GPS位置信息。终端设备的位置信息为发生上述失败时终端设备的有效的位置信息，终端设备的时间信息为终端设备上报失败信息的时间与发生上述失败时的时间之间的时间间隔。
主基站或辅基站可以根据终端设备的位置信息确定在哪些位置有上行覆盖问题和/或下行覆盖问题，也可以根据终端设备的时间信息确定在哪个时间出现了上述问题。
可选地，主基站或辅基站接收到终端设备发送的失败信息之后，主基站或辅基站将失败信息发送给跟踪收集实体(Trace collection entity，TCE)。可选地，主基站或辅基站可以在接收到操作维护管理(Operation Administration and Maintenance，OAM)实体下发的连接失败上报配置或其他上报配置之后，再将失败信息发送给TCE。其中，TCE可以根据失败信息，进行上行覆盖和/或下行覆盖的判断。TCE可以根据终端设备的位置信息确定在哪些位置有上行覆盖问题和/或下行覆盖问题，也可以根据终端设备的时间信息确定在哪个时间出现了上述问题。
在另外一些实施例中，提供了一种通信方法(该方法可以独立于上述各实施例中的方法来实施，也可以与上述任一实施例中的方法结合实施)：终端设备在上报日志记录或上报测量报告(例如向主基站或辅基站上报)时，终端设备可以携带终端设备的方向信息。该方向信息可包括终端设备从传感器(比如指南针compass或陀螺仪gyroscope)中获取的终端设备方向信息，比如终端设备的移动方向或终端设备的前端朝向信息。该方向信息可以是终端设备在全球坐标系(global coordination system)中的方向信息。
对于logged MDT而言，终端设备把每个可用的方向信息在即将到来的测量记录中只记录一次，然后该方向信息会被丢弃。也就是说方向信息的有效性是假定在一个记录周期中的。
当终端设备在周期性记录logged MDT信息时，当终端设备的方向信息在最近的一个或本次或上次的记录周期中变得可用时，在本次周期性记录中记录终端设备的方向信息。
另外，网络侧还可以请求终端设备获取具体的方向信息，比如网络侧给终端设备发送一个请求信息。当终端设备收到该请求信息时，终端设备尝试在后续的测量上报中携带可用的方向信息。另外，网络侧在请求进行测量上报(该测量上报可以是其他的测量上报,比如无线资源管理中移动性对应的测量上报，比如下行信号质量上报等，比如信号质量低于一定门限的上报)时，还可以在这些测量上报对应的测量配置中携带一个指示信息，指示在测量报告中携带终端设备方向信息。可选地，网络侧还可以单独给终端设备下发一个上报方向信息的测量任务。
当终端设备在测量上报时，如果该测量上报对应测量标识对应的测量配置中携带了上报终端设备的方向信息的指示，且可用的方向信息之前没有上报过，则可以在测量报告中携带方向信息。对于某个具体的方向信息而言，终端设备可以只在测量上报中携带一次。对于测量上报而言，当该测量报告是在获取具体的方向信息被获取之后的一个有效时间内上报的，则可以在测量上报中携带终端设备的方向信息。具体的有 效评估方法，由终端设备自己决定。
比如，对于immediate MDT而言，网络侧可以请求终端设备去尝试使得终端设备的方向信息可用。终端设备应该在immediate MDT的测量报告中提供新的(fresh)方向信息。具体细节可以由终端设备内部实现来决定。
当终端设备被请求去尝试使得终端设备的方向信息可用，以便在那些需要携带方向信息的测量报告中携带时，终端设备可能并不会成功(比如由于用户手工关掉了一些传感器)。具体的细节(比如什么时候激活那些传感器)由终端设备内部实现决定。
可选地，以上的方向信息可能还和终端设备当前上报的位置信息有关联，即代表终端设备在该上报的当前位置时对应的方向信息。
需要说明的是，上述各实施例可以单独实施，也可以是至少两个实施例任意结合来实施，对此不做限定。
可以理解的是，上述各个实施例中，由终端设备实现的方法或者步骤，也可以由可用于终端设备的部件(例如芯片或者电路等)实现，由网络设备实现的方法或者步骤，也可以由可用于网络设备的部件(例如芯片或者电路等)实现。
