Description

一种通信方法、装置及计算机可读存储介质
本申请要求于2020年04月29日提交中国专利局、申请号为202010358470.0、申请名称为“一种通信方法、装置及计算机可读存储介质”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
本发明实施例涉及通信技术领域，尤其涉及一种通信方法、装置及计算机可读存储介质。
背景技术
卫星通信即地球上(包括地面和低层大气中)的无线电通信站间利用卫星作为中继而进行的通信。卫星通信系统由卫星和地球站两部分组成。卫星通信的特点：通信范围大；只要在卫星发射的电波所覆盖的范围内，从任何两点之间都可进行通信；不易受陆地灾害的影响(可靠性高)；只要设置地球站电路即可开通(开通电路迅速)；同时可在多处接收，能经济地实现广播、多址通信(多址特点)；电路设置非常灵活，可随时分散过于集中的话务量；同一信道可用于不同方向或不同区间(多址联接)。在卫星通信中，很多卫星与地面之间不是相对静止，即卫星与地面之间的位置是不断变动的，为了保证终端设备正常通信，需要检测和优化网络中的问题和故障。为了检测和优化网络中的问题和故障，终端设备需要进行测量和上报。运营商可以通过签约用户的商用终端设备进行测量和上报，以便可以实现自动收集终端设备的测量数据。而终端设备进行测量和上报会影响终端设备本身数据的传输和终端设备电量的使用时长，以致降低了终端设备通信的服务质量。
发明内容
本发明实施例公开了一种通信方法、装置及计算机可读存储介质，用于提高终端设备通信的服务质量。
第一方面公开一种通信方法，该方法可以应用于终端设备，也可以应用于终端设备中的模块(例如，芯片)，下面以应用于终端设备为例进行描述。该方法可以包括：终端设备确定过滤条件，过滤条件为不进行测量和/或上报的条件；根据过滤条件进行测量；根据过滤条件向网络设备上报测量结果。
本发明实施例中，在需要检测和优化网络中的问题和故障的情况下，终端设备可以对满足过滤条件的信息不进行测量和/或上报，只对不满足过滤条件的信息进行测量和/或上报。可见，不需要对所有的信息进行测量和/或上报，可以减少终端设备测量和/或上报的信息，可以减少终端设备测量和/或上报对终端设备本身数据传输的影响，从而可以提高终端设备通信的服务质量。此外，由于减少了终端设备测量和/或上报的信息，因此，不仅可以节约时频资源，而且还可以节约终端设备的电量，可以进一步提高终端设备通信的服务质量。进一步地，由于减少终端设备测量和/或上报的信息，以致减少了网络设备需要处理的信息，可以节约网络设备的资源和电量，从而可以提高网络设备通信的服务质量。
作为一种可能的实施方式，终端设备确定过滤条件，可以是终端设备接收来自网络设备的过滤条件，也可以是终端设备获取过滤条件。
本发明实施例中，过滤条件可以是网络设备配置的，以便终端设备可以基于网络设备配置的过滤条件不进行测量和/或上报。过滤条件也可以是终端设备生成的，终端设备可以自主生成不进行测量和/或上报的过滤条件，可以提高终端设备的自主权。
作为一种可能的实施方式，终端设备获取过滤条件之前，还可以根据终端设备能够获取的信息生成过滤条件。
本发明实施例中，终端设备是根据终端设备能够获取的信息生成过滤条件的，可以保证终端设备生成的过滤条件的合理性。
作为一种可能的实施方式，终端设备能够获取的信息可以包括时间信息、地理位置信息、信号强度、终端设备的能力信息和终端设备的类型中的一种或多种。
作为一种可能的实施方式，过滤条件可以包括以下的一项或多项：对特定时间或特定时间段不进行测量和/或上报；对特定地理位置不进行测量和/或上报；对特定事件不进行测量和/或上报；对特定小区不进行测量和/或上报；在终端设备处于节能状态的情况下，不进行测量和/或上报；在终端设备为物联网终端设备的情况下，不进行测量和/或上报；在终端设备的电量小于或等于阈值的情况下，不进行测量和/或上报。
本发明实施例中，由于根据卫星的星历图等信息可以确定卫星的覆盖范围会在某个时间或某个时间段在地面的某个地理位置发生变化，因此，这个时间或这个时间段在地面的这个地理位置上的终端设备会发生切换失败(handover failure，HOF)、无线链路失败(radio link failure，RLF)、随机接入信道(random access channel，RACH)、RRC建立失败、RRC恢复失败等，按照现有机制，终端设备将对这些事件进行记录，并在进入连接态后给网络设备发指示有上述报告，网络设备下发指令让终端设备进行上报。由于卫星网络中，组网不断变动，发生上述事件的频率远高于地面网络。更重要的原因是，在两个卫星交接的过程中，即卫星A由于飞行到无法覆盖终端设备的区域，由卫星B来覆盖卫星A原来的覆盖的区域的变化瞬间，由于非静止卫星飞行速度非常快，如7千米每秒，终端设备有很大的概率发生HOF、RLF、重新RACH、RRC建立失败、RRC恢复失败等中的一种或者多种。并且，由于非静止卫星飞行速度快，一个特定卫星与终端设备连接时间很短，如15秒。因此，如果非地面网络(non-terrestrial network，NTN)中仍然沿用现有机制，那终端设备将花费大量的时间和信令来上报这些事件对网络进行优化。使得卫星通信的质量大幅度恶化。由于两个卫星交接的时间和位置，可以通过星历图等方式提前预知，因此，网络设备或者终端设备可以将这个时间或这个时间段下这个地理位置确定为过滤条件，以便终端设备在这个时间或这个时间段处于这个地理位置的情况下，不需要进行测量和/或上报，从而可以减少占用大量的时频资源，同时可以节约终端设备的电量，从而可以提高终端设备通信的服务质量。此外，由于各种事件在两个卫星交接发生时会重复出现，该过滤机制也可以让网络设备不需要处理大量重复的报告，可以节约网络设备的资源和电量，从而可以提高网络设备通信的服务质量。根据上述描述可知，在上述过程中，终端设备有很大的概率发生HOF、RLF、重新RACH、RRC建立失败、RRC恢复失败等中的一种或者多种，因此，网络设备或者终端设备可以将这些事件确定为过滤条件，以便终端设备对这些事件不进行测量和/或上 报，从而可以减少占用大量的时频资源，同时可以节约终端设备的电量，从而可以提高终端设备通信的服务质量。此外，由于各种事件在两个卫星交接发生时会重复出现，该过滤机制也可以让网络设备不需要处理大量重复的报告，可以节约网络设备的资源和电量，从而可以提高网络设备通信的服务质量。在测量对象为卫星投射的小区等特定小区的情况下，可能由于卫星的移动等原因导致终端设备会发生HOF、RLF、RACH、RRC建立失败、RRC恢复失败等，因此，可以将测量对象为特定小区确定为过滤条件，以便终端设备处于这些小区时，不需要进行测量和/或上报，从而可以减少占用大量的时频资源，同时可以节约终端设备的电量，从而可以提高终端设备通信的服务质量。此外，由于各种事件在两个卫星交接发生时会重复出现，该过滤机制也可以让网络设备不需要处理大量重复的报告，可以节约网络设备的资源和电量，从而可以提高网络设备通信的服务质量。在终端设备处于节能状态、终端设备为物联网终端设备或终端设备的电量较少时，终端设备进行测量和/或上报，对终端设备的危害较大，如可能导致终端设备没有足够的电量支撑正的数据传输等，因此，可以将终端设备处于节能状态、终端设备为物联网终端设备、终端设备的电量小于或等于阈值等中的一个或多个确定为过滤条件，以便终端设备在不适合测量和/或上报的情况下，可以不进行测量和/或上报，优先处理重要的业务，如数据传输、通话等。
作为一种可能的实施方式，测量可以为最小化路测(minimization drive test，MDT)，也可以为自组织网络(self organization network，SON)，还可以为MDT和SON。此外，测量还可以为除上面测量之外的其它测量，在此不加限定。
第二方面公开一种通信方法，该方法可以应用于网络设备，也可以应用于网络设备中的模块(例如，芯片)，下面以应用于网络设备为例进行描述。该方法可以包括：网络设备确定终端设备的过滤条件，过滤条件为不进行测量和/或上报的条件；向终端设备发送过滤条件，过滤条件用于指示终端设备根据过滤条件进行测量和/或上报。
本发明实施例中，终端设备可以根据网络设备的指示，在需要检测和优化网络中的问题和故障的情况下，可以对满足过滤条件的信息不进行测量和/或上报，只对不满足过滤条件的信息进行测量和/或上报。可见，终端设备不需要对所有的信息进行测量和/或上报，可以减少终端设备测量和/或上报的信息，可以减少终端设备测量和/或上报对终端设备本身数据传输的影响，从而可以提高终端设备通信的服务质量。此外，由于减少了终端设备测量和/或上报的信息，因此，不仅可以节约时频资源，而且还可以节约终端设备的电量，可以进一步提高终端设备通信的服务质量。进一步地，由于减少终端设备测量和/或上报的信息，以致减少了网络设备需要处理的信息，可以节约网络设备的资源和电量，从而可以提高网络设备通信的服务质量。
作为一种可能的实施方式，网络设备确定终端设备的过滤条件，可以是根据终端设备能够获取的信息生成终端设备的过滤条件。
本发明实施例中，网络设备是根据终端设备能够获取的信息生成过滤条件，可以保证网络设备为终端设备生成的过滤条件的合理性。
作为一种可能的实施方式，终端设备能够获取的信息可以包括时间信息、地理位置信息、信号强度、终端设备的能力信息和终端设备的类型中的一种或多种。
作为一种可能的实施方式，过滤条件可以包括以下的一项或多项：对特定时间或特定时间段不进行测量和/或上报；对特定地理位置不进行测量和/或上报；对特定事件不进行测量和/或上报；对特定小区不进行测量和/或上报；在终端设备处于节能状态的情况下，不进行测量和/或上报；在终端设备为物联网终端设备的情况下，不进行测量和/或上报；在终端设备的电量小于或等于阈值的情况下，不进行测量和/或上报。
本发明实施例中，由于根据卫星的星历图等信息可以确定卫星的覆盖范围会在某个时间或某个时间段在地面的某个地理位置发生变化，因此，这个时间或这个时间段在地面的这个地理位置上的终端设备会发生HOF、RLF、RACH、RRC建立失败、RRC恢复失败等，按照现有机制，终端设备将对这些事件进行记录，并在进入连接态后给网络设备发指示有上述报告，网络设备下发指令让终端设备进行上报。由于卫星网络中，组网不断变动，发生上述事件的频率远高于地面网络。更重要的原因是，在两个卫星交接的过程中，即卫星A由于飞行到无法覆盖终端设备的区域，由卫星B来覆盖卫星A原来的覆盖的区域的变化瞬间，由于非静止卫星飞行速度非常快，如7千米每秒，终端设备有很大的概率发生HOF、RLF、重新RACH、RRC建立失败、RRC恢复失败等中的一种或者多种。并且，由于非静止卫星飞行速度快，一个特定卫星与终端设备连接时间很短，如15秒。因此，如果非地面网络(non-terrestrial network，NTN)中仍然沿用现有机制，那终端设备将花费大量的时间和信令来上报这些事件对网络进行优化。使得卫星通信的质量大幅度恶化。由于两个卫星交接的时间和位置，可以通过星历图等方式提前预知，因此，网络设备或者终端设备可以将这个时间或这个时间段下这个地理位置确定为过滤条件，以便终端设备在这个时间或这个时间段处于这个地理位置的情况下，不需要进行测量和/或上报，从而可以减少占用大量的时频资源，同时可以节约终端设备的电量，从而可以提高终端设备通信的服务质量。此外，由于各种事件在两个卫星交接发生时会重复出现，该过滤机制也可以让网络设备不需要处理大量重复的报告，可以节约网络设备的资源和电量，从而可以提高网络设备通信的服务质量。根据上述描述可知，在上述过程中，终端设备有很大的概率发生HOF、RLF、重新RACH、RRC建立失败、RRC恢复失败等中的一种或者多种，因此，网络设备或者终端设备可以将这些事件确定为过滤条件，以便终端设备对这些事件不进行测量和/或上报，从而可以减少占用大量的时频资源，同时可以节约终端设备的电量，从而可以提高终端设备通信的服务质量。此外，由于各种事件在两个卫星交接发生时会重复出现，该过滤机制也可以让网络设备不需要处理大量重复的报告，可以节约网络设备的资源和电量，从而可以提高网络设备通信的服务质量。在测量对象为卫星投射的小区等特定小区的情况下，可能由于卫星的移动等原因导致终端设备会发生HOF、RLF、RACH、RRC建立失败、RRC恢复失败等，因此，可以将测量对象为特定小区确定为过滤条件，以便终端设备处于这些小区时，不需要进行测量和/或上报，从而可以减少占用大量的时频资源，同时可以节约终端设备的电量，从而可以提高终端设备通信的服务质量。此外，由于各种事件在两个卫星交接发生时会重复出现，该过滤机制也可以让网络设备不需要处理大量重复的报告，可以节约网络设备的资源和电量，从而可以提高网络设备通信的服务质量。在终端设备处于节能状态、终端设备为物联网终端设备或终端设备的电量较少时，终端设备进行测量和/或上报，对终端设备的危害较大，如可能导致终端设备没有足够的电量支撑正的数据传输等，而网络设 备对终端设备的状态并不是完全可知的，因此，可以将终端设备处于节能状态、终端设备为物联网终端设备、终端设备的电量小于或等于阈值等中的一个或多个确定为过滤条件，以便终端设备在不适合测量和/或上报的情况下，可以不进行测量和/或上报，优先处理重要的业务，如数据传输、通话等。

具体实施方式
本发明实施例公开了一种通信方法、装置及计算机可读存储介质，用于提高终端设备通信的可靠性。
为了更好地理解本发明实施例公开的一种通信方法、装置及计算机可读存储介质，下面先对本发明实施例的一些用语或概念进行描述。
1、无线资源控制(radio resource control，RRC)状态
在新无线(new radio，NR)中，终端设备的RRC状态可以包括RRC连接态(RRC_CONNECTED)、RRC去激活态或者第三态(RRC_INACTIVE)和RRC空闲态(RRC_IDLE)。当终端设备处于RRC_CONNECTED时，终端设备与基站之间以及基站与核心网之间均建立有链路，当有数据到达网络时，网络可以直接将数据传送给终端设备。当终端设备处于RRC_INACTIVE时，基站与核心网之间建立了链路，终端设备与基站之间的链路被释放了，虽然终端设备与基站之间的链路被释放了，但是基站存储有终端设备的上下文，当有数据需要传输给终端设备时，基站可以根据终端设备的上下文快速恢复终端设备与基站之间的链路。当终端设备处于RRC_IDLE状态时，在终端设备与基站之间以及基站与核心网之间都没有链路，当有数据需要传输时，需要建立终端设备与基站之间以及基站与核心网之间的链路。请参阅图1，图1是本发明实施例公开的一种RRC状态的转换示意图。如图1所示，在终端设备处于RRC连接态时，终端设备与基站之间以及基站与核心网之间的链路被释放(release)后，终端设备将由RRC连接态转换为RRC空闲态。在终端设备处于RRC空闲态时，建立(establish)终端设备与基站之间以及基站与核心网 之间的链路后，终端设备将由RRC空闲态转换为RRC连接态。在终端设备处于RRC去激活态时，基站与核心网之间的链路被释放后，终端设备将由RRC去激活态转换为RRC空闲态。在终端设备处于RRC去激活态时，终端设备与基站之间的链路被恢复(resume)后，终端设备将由RRC去激活态转换为RRC连接态。在终端设备处于RRC连接态时，终端设备与基站之间的链路被释放(即暂停释放(release with suspend))后，终端设备将由RRC连接态转换为RRC去激活态。
2、卫星通信
卫星通信，即NTN通信，从19世纪60年代至今一直是研究领域的热门。通常来说，卫星的轨道越高其覆盖面积越大，但通信时延也越长。请参阅图2，图2是本发明实施例公开的一种卫星轨道的示意图。如图2所示，卫星的运行轨道根据高度可以分为：
(1)低轨道(low earth orbit，LEO)：轨道高度为160km～2000km；
(2)中轨道(medium earth orbit，MEO)：轨道高度为2000km～35786km；
(3)同步轨道(geosychronons earth orbit，GEO)：轨道高度为35786km，运行在此轨道上的卫星与地球的相对位置不受地球自转的影响；
(4)高椭圆轨道(highly eccentric orbit，HEO)：是一种具有较低近地点和极高远地点的椭圆轨道，其远地点高度大于GEO卫星的高度。
其中，处于LEO的卫星距离地面近、通信时延短、数据传输率高，终端设备的重量和体积可以与个人移动设备相差无几，更适合大众市场普及，成为当前产业发展的热点。
请参阅图3，图3是本发明实施例公开的一种卫星通信的网络示意图。如图3所示，将信息由源地发送到目的地时，在地面上可以使用蜂窝子网(cellular subnetwork)，在低空(low altitude)可以使用低空平台(low altitude platform，LAP)子网，在高空可以使用高空平台(high altitude platform，HAP)子网，在外太空可以使用卫星通信子网。
3、测量机制
移动性管理是无线移动通信中的重要组成部分。移动性管理指的是为了保证网络设备与终端设备之间的通信链路不因终端设备的移动而中断所涉及到的相关内容的统称。根据终端设备的RRC状态可以将移动性管理分为空闲态(RRC_IDLE state)移动性管理和连接态(RRC_CONNECTED state)移动性管理。在终端设备处于RRC空闲态或RRC去激活态的情况下，移动性管理包括小区选择/重选(cell selection/reselection)过程，在终端设备处于RRC连接态的情况下，移动性管理包括小区切换(cell handover)过程。不论是小区选择/重选还是小区切换，都是基于测量结果进行的。因此，移动性测量是移动性管理的基础。
请参阅图4，图4是本发明实施例公开的一种移动性测量的流程示意图。如图4所示，可以根据涉及到的层次将移动性测量划分为物理层测量(即层1测量)和RRC层测量(即层3测量)。在物理层测量中，终端设备可以在配置的测量资源上进行指定类型的测量。对于基于单边带(single side band，SSB)的测量而言，终端设备可以对多个具有相同的SSB索引(index)和物理小区标识(physical cell identifier，PCI)的SSB上得到的测量结果进行合并，得到该PCI对应的小区的该SSB索引对应的SSB的波束(beam)级的层1测量结果，并上报给层3。对于基于信道状态信息参考信号(channel state information reference signal，CSI-RS)的测量而言，终端设备可以对多个具有相同CSI-RS资源标识(resource identifier) 和PCI的CSI-RS资源上得到的测量结果进行合并，得到该PCI对应的小区的该CSI-RS资源标识对应的CSI-RS资源的波束级的层1测量结果，并上报给层3。上述对于多个测量资源上的测量结果进行合并的过程就是所谓的图4所示的层1滤波。具体的合并方式可以是终端设备根据时延、精度等确定的。
层3在接收到层1上报的波束级测量结果后，终端设备需要对同一小区的各个波束的层1测量结果进行选择/合并以推导出该小区级的层3测量结果。之后还需要对得到的小区级的层3测量结果进行层3滤波。只有层3滤波后的测量结果才会用于验证上报触发条件是否满足，从而进行最终的上报。
此外，根据配置，终端设备也可能需要上报波束级的层3测量结果。此时终端设备可以直接对各个波束的层1测量结果进行层3滤波，再在滤波后的测量结果中选择出要上报的测量结果进行上报。
终端设备至少应该在有新的小区级测量结果产生的时候对上报触发条件进行验证。当上报触发条件满足时，终端设备需要向网络设备发送测量报告。
4、MDT
MDT，即最小化路测技术。该技术的基本思想是运营商可以通过签约用户的商用终端设备进行测量上报来部分替代传统的路测工作，以便实现自动收集终端设备的测量数据，从而可以检测和优化无线网络中的问题和故障。运营商一般每个月都要做例行的网络覆盖路测，针对用户投诉也会做一些针对特定区域的呼叫质量路测，这些场景的路测都可以用MDT代替。现有的MDT技术的测量类型可以包括以下几种：
1、信号水平测量：由终端设备测量无线信号的信号水平，将测量结果上报给基站或基站控制器；
2、服务质量(quality of service，QoS)测量：可以由基站进行QoS测量，如业务的流量、业务的吞吐量、业务的时延等的测量，也可以由终端设备进行QoS测量，例如，上行处理时延的测量，还可以由基站和终端设备联合进行QoS测量，例如，空口时延测量，即测量数据包经过基站的服务数据适配协议(service data adaptation protocol，SDAP)/包数据汇聚协议(package data convergence protocol，PDCP)层到该数据包到达终端设备的SDAP/PDCP层的时间。
3、可接入性测量：由终端设备记录RRC连接建立失败的信息，并上报给基站或基站控制器。
MDT可以包括已登录的(logged)MDT和即时(immediate)MDT。immediate MDT主要针对处于RRC连接态(即RRC_CONNECTED)的终端设备进行测量，网络设备可以指示终端设备进行实时测量和上报。该测量可以包括无线资源管理(radio resources management，RRM)测量、物理层(physical，PH)测量、上行链路(up link，UL)PDCP时延测量、体验质量(quality of experience，QoE)测量、无线保真(wireless fidelity，WiFi)测量、蓝牙测量等。RRM测量可以包括参考信号接收功率(reference signal received power，RSRP)测量、参考信号接收质量(reference signal received quality，RSRQ)测量、接收信号强度指示(received signal strength indicator，RSSI)测量等。immediate MDT一般用于测量终端设备的数据量、网络协议(internetprotocol，IP)吞吐率、包传输时延、丢包率、处理时延等。
logged MDT主要针对处于RRC空闲态(即RRC_IDLE)的终端设备或RRC去激活态(即RRC_INACTIVE)的终端设备进行测量。logged MDT测量结果中的每条Logged记录(record)可以包括相对时间戳(relative time stamp)、NR小区全局标识(NR cell global identifier，NCGI)、服务小区测量结果、邻区测量结果、无线局域网(wireless local area network，WLAN)测量结果、传感器(sensor)测量结果等。可选地，logged MDT测量结果中的每条Logged记录(record)还可以包括终端设备的位置信息。服务小区测量结果可以包括PCI、小区RSRP/RSRQ、最好波束索引(beam index)、最好波束的RSRP/RSRQ、好波束的数量等。logged MDT一般指终端设备对接收信号强度的测量。
NR中还定义了一些L2测量，用于网络设备统计一些网络性能，以便进行无线链路管理、无线资源管理、网络维护等功能。这些L2测量是针对一个终端设备进行统计的，如业务的吞吐量、业务的流量、终端设备的处理时延、终端设备的空口时延等。
基站发起的MDT测量可以为基于信令的MDT(signalling based MDT)，也可以为基于管理的MDT(management based MDT)。基于信令的MDT是指针对某特定终端设备的MDT，基站会接收到来自核心网(core network，CN)的对某个终端设备进行MDT的消息。基于管理的MDT并不是针对特定终端设备的MDT，基站是从操作维护管理(operation administration and maintenance，OAM)收到进行MDT的消息。基站基于一定策略从该基站下的终端设备中选择终端设备进行MDT测量。对于基于信令的MDT而言，除非终端设备已经同意进行MDT，否则CN并不会发起针对该终端设备的基于信令的MDT。对于基于管理的MDT而言，基站在选择终端设备时，可以考虑终端设备是否同意进行MDT，例如，可以只选择那些已经同意进行MDT的终端设备进行MDT测量。例如，CN会通知基站，某个终端设备是否同意进行MDT。再例如，CN通知基站该终端设备的基于管理的MDT允许指示(Management Based MDT Allowed indication)消息。可选地，CN也会通知基于管理的MDT的公共陆地移动网络(public land mobile network，PLMN)列表。这两种MDT都可以包括logged MDT和immediated MDT。对于基于信令的MDT而言，CN会把一些MDT配置信息、跟踪收集实体(trace collection entity，TCE)IP地址通知给基站。MDT配置信息可以包括MDT的激活类型、MDT的区域范围、MDT的模式、MDT的模式的配置参数、基于信令的MDT的PLMN列表等。MDT的激活类型可以包括仅限即时MDT(immediate MDT only)、仅限记录的MDT(logged MDT only)、即时MDT和跟踪(immediate MDT and trace)等。MDT的模式的配置参数可以包括immediate MDT的测量事件、logged MDT的记录间隔、logged MDT的持续时间等。
请参阅图5，图5是本发明实施例公开的一种logged MDT的流程示意图。如图5所示，首先终端设备与网络设备进行RRC建立。RRC建立过程完成后，网络设备可以选择用于MDT任务的终端设备，之后向终端设备发送记录的MDT配置(logged MDT configuration)消息。即当终端设备处于RRC连接态时，基站会给终端设备配置logged MDT测量相关配置，基站可以通过RRC消息通知logged MDT相关配置。之后进行RRC释放。RRC释放过程完成之后，终端设备处于RRC空闲态/RRC去激活态，终端设备进行已登录数据收集(logged MDT data collection)。即当终端设备进入到RRC空闲态或RRC去激活态时，终端设备会按照对应的配置记录对应的测量结果。之后进行RRC建立/恢复，在RRC建立/恢复过程中，终端设备向 网络设备发送记录的MDT可用指示(logged MDT availability indicator)消息。即当终端设备向网络发起RRC连接时，在RRC消息中可以携带一个指示信息，这个指示信息用于指示当前终端设备记录了logged MDT的测量结果。在RRC建立/恢复过程完成后，网络设备可以向终端设备发送UEInformationRequest消息。即网络设备可以向终端设备发送用于获取logged MDT记录的请求。终端设备接收到来自网络设备的UEInformationRequest消息之后，可以向网络设备发送UEInformationResponse消息。即终端设备接收到该请求之后，可以向网络设备上报logged MDT的测量结果。例如，终端设备可以在RRC建立完成(RRCSetupComplete)消息中携带该指示信息，网络设备可以在UEInformationRequest消息中向终端设备请求获取logged MDT记录，该消息中携带一个请求指示信息，用于指示终端设备向网络设备上报logged MDT记录，之后终端设备在UEInformationResponse消息中向网络设备上报logged MDT记录。其中。给终端设备下发logged MDT测量相关配置的网络设备可能与终端设备上报logged MDT的测量结果的网络设备并不是同一个网络设备。
对于一些流类业务或者语音业务而言，如流媒体业务(streaming service)、IP多媒体子系统(IP multimedia subsystem，IMS)多媒体电话业务(multimedia telephony service for IMS，MTSI)业务等，单纯的信号质量并不能体现用户在使用这些业务时的用户体验，因此，运营商想知道用户的体验，以便更好地优化网络以提高用户体验。这类测量收集可以称为QoE测量收集，也可以称为应用层测量收集。这类测量可以利用基于信令的MDT和基于管理的MDT进行发起。基站从CN或OAM收到这些测量的配置信息之后，基站可以把这些配置信息通过RRC消息发送给终端设备。终端设备的RRC层从终端设备的上层收到应用层的测量结果之后，可以将这些测量结果发送给基站。CN或OAM发送给基站的配置信息，以及终端设备向基站发送的测量结果，可以是以一种透明容器的封装形式发送的。基站从CN或OAM接收的信息除了以上的测量的配置信息之后，还可以包括QoE测量的其他信息，如QoE测量的区域范围、QoE测量的业务类型等。基站选择终端设备进行QoE测量的方法与普通的MDT测量基本相同。对于QoE测量，网络设备可以为终端设备配置一个信令承载(signalling radio bearer，SRB)，如SRB4，来传输QoE测量结果。终端设备可以通过该信令承载来上报QoE测量结果。其中，给终端设备下发QoE测量相关配置的网络设备与终端设备上报QoE测量结果的网络设备可能不是同一个网络设备。请参阅图6，图6是本发明实施例公开的一种QoE测量的流程示意图。如图6所示，网络设备可以向终端设备发送QoE配置，终端设备向网络设备发送QoE测量报告。
5、SON
SON不需要增加网络的设备，可以最大化的利用现有的设备，以便减小运营成本。
SON主要包括自动邻区关系(automatic neighbour relation，ANR)、PCI分配(selection)、移动鲁棒性优化(mobility robustness optimisation，MRO)、移动负载平衡(mobility load balancing，MLB)、节能(energy saving，ES)、MDT、容量优化(coverageand capacity optimization，CCO)等。
对于设备的利用，讲究最大化和高性能。例如，可以利用负载平衡、覆盖容量优化、不增加新设备来完成覆盖优化，可以利用移动性优化、随机接入优化等来达到利用现有设备提高较大的性能。
对于成本，可以通过减少操作维护人员的数量和降低对操作维护人员的技能来达到要求。可以利用MDT技术来达到减少人工路侧的成本，可以利用ES技术来达到节能的效果。可以通过自动维护过程来提高系统的性能。
SON技术的终极目标是实现网络规划、优化的完全自动化，从而实现真正意义上的自组织网络。
SON是通过自动生成的网络配置参数，不断地自动优化这些配置参数。
在第三代合作伙伴计划(3rd generation partnership project，3GPP)中，定义了一些用于SON研究的用例(use case)。3GPP定义的用例可以包括ANR、PCI选择、移MRO、MLB、ES、MDT、覆盖范围和CCO等。
在NR中，也定义了一些用于SON研究的用例。NR定义的用例可以包括MRO、PCI选择、MLB、ES，MDT、CCO等。此外，NR还引入了一些新的功能，如车与任何事物(vehicle to everything，V2X)SON等。
为了更好地理解本发明实施例公开的一种通信方法、装置及计算机可读存储介质，下面先对本发明实施例使用的网络架构进行描述。其中，本发明实施例公开的一种通信方法、装置及计算机可读存储介质可以应用于各种基于NTN的通信系统，如基于NTN的第四代移动通信技术(the 4th generation mobile communication technology，4G)通信系统、基于NTN的第五代移动通信技术(the 5th generation mobile communication technology，5G)通信系统、将来的基于NTN的通信系统等。现有通信标准中定义了五种基于NTN的无线接入网(radio access network，RAN)设备架构。请参阅图7，图7是本发明实施例公开的一种网络架构示意图。其中，图7所示的网络架构中采用透明卫星的RAN设备架构(RAN architecture with transparent satellite)。如图7所示，该网络架构可以包括终端设备701、RAN设备702、核心网设备703和数据网络(data network，DN)704。RAN设备702可以包括射频拉远单元(remote radio unit，RRU)和基站。RRU可以包括卫星和NTN网关(gateway)。终端设备701可以通过卫星和NTN网关接入基站。其中，在透明(transparent)场景下，卫星用于射频滤波(radio frequency filtering)和频率转换和放大(frequency conversion and amplification)，以便保证有效载荷重复的波形信号保持不变(the waveform signal repeated by the payload is un-changed)。即卫星主要作为L1层的中继设备(L1relay)，用于重新生成物理层信号，该物理层信号高层不可见。
请参阅图8，图8是本发明实施例公开的另一种网络架构示意图。其中，图8所示的网络架构中的再生(regenerative)卫星没有卫星间链路(inter-satellite link，ISL)，基站处理有效载荷。如图8所示，该网络架构可以包括终端设备801、RAN设备802、核心网设备803和DN804。RAN设备802包括基站和NTN网关，卫星作为基站。卫星与NTN网关通过卫星无线接口(satellite radio interface，SRI)连接。

终端设备可以为无线终端设备，也可以为有线终端设备。无线终端设备可以是向用户提供语音和/或数据连通性的设备，可以为具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端设备可以经RAN设备与一个或多个核心网设备进行通信。无线终端设备可以是移动终端设备，例如，可以是移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机。再例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。再例如，可以是个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)等设备。无线终端设备也可以称为系统、订户单元(subscriber unit，SU)、订户站(subscriber station，SS)，移动站(mobile station，MB)、移动台(mobile)、远程站(remote station，RS)、接入点(access point，AP)、远程终端(pemoteterminal，RT)、接入终端(access terminal，AT)、用户终端(user terminal，UT)、用户代理(user agent，UA)、用户设备(user device，UD)、或用户终端(user equipment，UE)。
RAN设备主要负责空口侧的无线资源管理、QoS管理、数据压缩和加密等功能。RAN设备可以包括各种形式的基站，例如：宏基站，微基站(也称为小站)，中继站，接入点等。AN设备允许终端设备和3GPP核心网之间采用非3GPP技术互连互通，非3GPP技术可以为无线保真(wireless fidelity，Wi-Fi)、全球微波互联接入(worldwide interoperability for microwave access，WiMAX)、码分多址(code division multiple access，CDMA)网络等。
RAN设备可以是CU和DU分离的，也可以是集中的。RAN设备与核心网设备相连。核心网设备可以是长期演进(long term evolution，LTE)中的核心网设备，也可以是5G中的核心网设备，还可以是其他通信系统中的核心网设备。
请参阅图11，图11是本发明实施例公开的一种CU和DU分离的RAN设备的结构示意图。如图11所示，RAN设备可以包括CU和DU。CU和DU可以理解为对RAN设备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。CU可以控制一个或多个DU的操作。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，可以通过是F1接口连接。CU和DU可以根据无线网络的协议层划分。作为一种可能的划分方式，CU用于执行RRC层、DAP层以及PDCP层的功能，而DU用于执行无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层、物理(physical)层等的功能。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。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。在一种可能的实施方式中，可以将RLC层 的部分功能和RLC层以上的协议层的功能设置在CU上，可以将RLC层的剩余功能和RLC层以下的协议层的功能设置在DU上。在一种可能的实施方式中，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，可以按时延划分，将处理时间需要满足时延要求的功能设置在DU上，不需要满足该时延要求的功能设置在CU上。在一种可能的实施方式中，CU也可以具有核心网设备的一个或多个功能。一个或者多个CU可以集中设置，也分离设置。例如，CU可以设置在网络设备方便集中管理。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(control panel，CP)和用户面(user panel，UP)分离，即CU的控制面(CU-CP)和CU的用户面(CU-UP)。例如，CU-CP和CU-UP可以由不同的功能实体来实现，CU-CP和CU-UP可以与DU相耦合，共同完成基站的功能。一个小区只由一个DU支持。请参阅图12，图12是本发明实施例公开的一种CP和UP分离的RAN设备的结构示意图。如图12所示，一个RAN设备可以包括一个CU-CP(即控制中心)、多个CU-UP和多个DU。一个DU只能连接一个CU-CP，一个CU-UP也只能连接一个CU-CP。同一个CU-CP控制下，一个DU可以连接多个CU-UP，一个CU-UP可以连接多个DU，即DU与CU-UP是M对N的关系。CU-CP集中部署，协调操作多个DU；CU-UP分布式部署，一个CU-UP与一个DU共部署。一个UE可以同时连接多个CU-UP，以协议数据单元(protocol data unit，PDU)会话(session)为粒度，一个PDU会话对应一个CU-UP。在核心网为5G核心网的情况下，CU-CP可以通过N2接口连接接入和移动性管理功能(access and mobility management function，AMF)网元，CU-UP可以通过N3接口连接用户面功能(user plane function，UPF)网元。CU-CP与CU-UP之间可以通过E1接口连接，CU-CP与DU之间可以通过F1-C接口连接，DU与CU-UP之间可以通过F1-U接口连接。

为了更好地理解本发明实施例公开的一种通信方法、装置及计算机可读存储介质，下面先对本发明实施例的应用场景进行描述。
卫星可以作为独立基站与核心网连接，也可以作为中继基站与地面连接，还可以作为DU与地面CU连接，还可以作为空中工作站。
由于GEO卫星是地球同步卫星，因此，不论是卫星还是投射到地面的小区，相对地面都是静止的。终端设备在GEO卫星小区进行小区选择、重选或者切换时，过程和现有的地面通信非常相似。
LEO卫星是绕着地球高速飞行的，其速度接近7km/s。LEO卫星投射到地面的小区有两种模式：
1、移动小区(moving cell)，即投射到地面的小区跟着卫星一起移动。其LEO卫星的 天线总是与地面垂直。LEO不论是作为独立基站还是中继基站，小区都是跟着LEO卫星一起移动。因此，LEO卫星与终端设备之间的相对距离一直在改变，一段时间后，LEO卫星的信号可能无法覆盖该终端设备。在网络部署比较完善的情况下，会有下一个的LEO卫星来覆盖该终端设备E。由于卫星系统是球状的，下一个LEO卫星可能来自各个角度。
2、固定小区(fixed cell)，即投射到地面的小区相对于地面静止，上空的LEO卫星通过调整天线角度完成地面同一位置的覆盖，等这个LEO卫星无法覆盖到地面这一位置的时候，由另一个LEO卫星接替。请参阅图13，图13是本发明实施例公开的一种固定小区的示意图。如图13所示，LEO卫星通过调整天线角度完成地面同一位置的覆盖。
MEO和HEO卫星的情况下，在此不加赘述。
可见，卫星通信有两个特点：
1、地面覆盖容易有偏差
卫星通信中的小区均比较大，小区直径从50kM到1000kM不等。由于卫星距离地球很远，所以卫星的天线角度或天线方向稍有偏移就会导致投射到地面的小区位置偏移几十千米到上百千米，以致引起小区偏移。卫星的天线角度即使相差一点，也会导致地面的信号覆盖范围相差千里。特别是LEO卫星的小区采用固定小区的情况下，卫星的天线角度一直在变，以此来保证地面投射的小区不变，实现难度大，而且容易出错。
2、变动多
由于很多卫星与地面之间不是相对静止，即卫星与地面之间的位置是不断变动的，因此，要保证地面一直有很好的信号覆盖，组网难度较大。例如，在LEO中，卫星的飞行速度是7km/s，LEO的小区直径为50km左右，这意味着处于LEO中的一个卫星给终端设备提供服务的时间只有7s左右，7s过后，终端设备需要进行小区重选或者切换到另外一个小区。
由于以上两个特点，卫星通信下的网络优化机制比一般的地面通信要频繁复杂得多。如果还是按照原来的MDT、SON等测量上报机制，可能导致频繁地上报，特别是在LEO模式下。由于在LEO模式下给终端设备提供的时间非常短，如果投入大量的时频资源用于做测量和上报，则会严重影响终端设备本身的传送数据功能。此外，目前，终端设备的测量和上报完全由网络设备配置决定，终端设备没有自主优化权。
请参阅图14，图14是本发明实施例公开的一种通信方法的流程示意图。其中，该通信方法是从终端设备的角度描述的，下面终端设备执行的步骤也可以由终端设备中的模块(例如，芯片)来执行。如图14所示，该通信方法可以包括以下步骤。
1401、确定过滤条件。
在终端设备需要进行测量和上报的情况下，终端设备确定过滤条件。过滤条件为不进行测量和/或上报的条件，可以为不进行测量的条件，也可以为不进行上报的条件，还可以为不进行测量和上报的条件。该测量为MDT测量，也可以为SON测量，还可以为MDT测量和SON测量，还可以其它测量。终端设备确定过滤条件，可以为终端设备接收来自网络设备的过滤条件，详细描述可以参考图17对应的描述，在此不加详述。也可以为终端设备获取过滤条件，该过滤条件可以是终端设备预先生成并存储的。还可以为终端设备生成过滤条件。
终端设备可以根据终端设备能够获取的信息生成过滤条件。终端设备能够获取的信息可以包括时间信息、地理位置信息、信号强度、终端设备的能力信息、终端设备的类型等中的一种或多种。信号强度可以为RSRP、RSRQ和信号与干扰加噪声比(signal to interference plus noise ratio，SINR)中一种或多种的信号强度。终端设备的能力信息可以为能接入卫星网络的能力、支持MDT/SON特性的能力等。终端设备的类型可以为LTE/NR终端设备、物联网终端设备，车联网终端设备等。过滤条件可以包括以下的一项或多项：对特定时间或特定时间段不进行测量和/或上报；对特定地理位置不进行测量和/或上报；对特定事件不进行测量和/或上报；对特定小区不进行测量和/或上报；在终端设备处于节能状态的情况下，不进行测量和/或上报；在终端设备为物联网终端设备的情况下，不进行测量和/或上报；在终端设备的电量小于或等于阈值的情况下，不进行测量和/或上报。
例如，终端设备可以根据已知的信息，如网络设备广播的星历图、来自应用层的信息等，得知在某个时间或者时间集合下某些地理位置必然发生HOF、RLF、RACH、RRC建立失败、RRC恢复失败等。按照现有机制，终端设备将对这些事件进行记录，并在进入连接态后给网络设备发指示有上述报告，网络设备下发指令让终端设备进行上报。由于卫星网络中，组网不断变动，发生上述事件的频率远高于地面网络。更重要的原因是，在两个卫星交接的过程中，即卫星A由于飞行到无法覆盖终端设备的区域，由卫星B来覆盖卫星A原来的覆盖的区域的变化瞬间，由于非静止卫星飞行速度非常快，如7千米每秒，终端设备有很大的概率发生HOF、RLF、重新RACH、RRC建立失败、RRC恢复失败等中的一种或者多种。并且，由于非静止卫星飞行速度快，一个特定卫星与终端设备连接时间很短，如15秒。因此，如果NTN中仍然沿用现有机制，那终端设备将花费大量的时间和信令来上报这些事件对网络进行优化，以致占用了大量的时频资源，对卫星通信的网络资源造成了侵占，使得卫星通信的质量大幅度恶化。此外，由于卫星特别远，终端设备上报大量的报告需要耗费较多的电量，对终端设备的电量造成了浪费。进一步地，由于各种事件在两个卫星交接发生时会重复出现，该过滤机制也可以让网络设备需要处理大量的重复报告，耗费算力和电量，而这些报告网络设备本来可以预计到，上报的意义不大。因此，终端设备可以将这些时间下这些地理位置作为过滤条件，以便终端设备在做测量时可以选择避开这些时间下这些地理位置下的HOF、RLF、RACH、RRC建立失败、RRC恢复失败等的测量和上报。上述的时间可以为相对时间，如过五分钟后，也可以为绝对时间，如协调世界时(coordinated universal time，UTC)。上述地理位置可以为相对地点，如距离某个参考地点的距离和方向，也可以为绝对地点，如经纬度信息。
再例如，根据上述描述可知，在上述过程中，终端设备有很大的概率发生HOF、RLF、重新RACH、RRC建立失败、RRC恢复失败等中的一种或者多种，因此，可以将这些事件确定为过滤条件，以便终端设备对这些事件不进行测量和/或上报，从而可以减少占用大量的时频资源，同时可以节约终端设备的电量，从而可以提高终端设备通信的服务质量。此外，由于各种事件在两个卫星交接发生时会重复出现，该过滤机制也可以让网络设备不需要处理大量重复的报告，可以节约网络设备的资源和电量，从而可以提高网络设备通信的服务质量。
再例如，由于网络设备并非完全知道终端设备的状态，如电量不多等，因此，在网络 设备选择终端设备进行测量和上报的情况下，可能会对终端设备产生较大的损害。例如，可能导致终端设备没有足够的电量支撑正常的数据传输业务。为了解决上述问题，终端设备可以将终端设备处于节能状态、终端设备为物联网终端设备、终端设备的电量小于或等于阈值等中的一个或多个确定为过滤条件。有了这些过滤条件，某些不太适合做上报的终端设备可以优先做更重要的业务，如数据传输、通话等，而不进行测量和/或上报。物联网终端设备可以为窄带物联网(narrow band internet of things，NB-IoT)终端设备，也可以为增强机器类通信(enhance machine type communication，eMTC)终端设备。
再例如，在测量对象为卫星投射小区等小区的情况下，这些小区可能由于卫星的移动等原因导致终端设备会发生HOF、RLF、RACH、RRC建立失败、RRC恢复失败等，因此，可以将测量对象为特定小区确定为过滤条件，以便终端设备处于这些小区时，不需要进行测量和/或上报，从而可以减少占用大量的时频资源，同时可以节约终端设备的电量，从而可以提高终端设备通信的服务质量。
1402、根据过滤条件进行测量。
终端设备确定出过滤条件之后，可以根据过滤条件进行测量，如进行MDT测量、SON测量等测量。可以先根据过滤条件确定哪些信息需要测量哪些信息不需要测量，之后针对需要测量的信息进行测量。
1403、根据过滤条件向网络设备上报测量结果。
终端设备根据过滤条件进行测量之后，即终端设备根据过滤条件测量完之后，可以根据过滤条件向网络设备上报测量结果。可以先根据过滤条件确定哪些信息需要上报哪些信息不需要上报，之后针对需要上报的信息进行上报。
例如，对RRC空闲态或RRC去激活态的终端设备当前驻留小区对应的频点的小区及当前驻留小区中广播的小区重选对应的异频/异系统相邻小区进行测量。当终端设备处于RRC连接态时，网络设备会为终端设备配置logged MDT相关的配置信息。终端设备接收到来自网络设备的配置信息之后，当终端设备进入RRC_IDLE或RRC_INACTIVE时，终端设备会根据配置信息进行测量，将测量结果缓存在终端设备内。在终端设备进入RRC_CONNECTED后，终端设备会在RRC建立/恢复/重建完成(RRC setup/resume/re-establishment Complete)等消息中指示是否有logged MDT测量结果。网络设备接收到来自终端设备的有logged MDT测量结果的指示信息之后，可以向终端设备下发用户设备(user equipment，UE)信息请求(UE Information Request)消息。终端设备接收到来自网络设备的UE Information Rrequest消息之后，可以通过UE信息响应(UE Information Response)消息向网络设备上报logged MDT测量结果。网络设备配置的上述配置信息可以包括过滤条件，终端设备接收到配置信息之后，可以根据过滤条件进行测量和/或上报。终端设备接收到来自网络设备的配置信息之后，可以生成过滤条件或获取存储的过滤条件，之后可以根据过滤条件和配置信息确定需要进行测量和/或上报的信息，之后执行上述后面相关步骤。
例如，L2测量可以包括无线链路测量，无线链路测量结果可以包括RLF报告(report)。RLF report可以包括RLF、HOF等。终端设备在发生RLF、HOF等失败后，可以记录这些失败，以便终端设备进入RRC连接态后可以在RRC重建完成(RRC re-establishment Complete) 消息中指示是否有RLF信息(RLF Info)。网络设备接收到来自终端设备的有RLF Info的指示信息之后，可以向终端设备下发UE Information Request消息。终端设备接收到来自网络设备的UE Information Rrequest消息之后，可以通过UE Information Response消息向网络设备上报RLF report。L2测量还可以包括接入性测量(accessibility measurements)，接入性测量结果可以包括RRC连接建立失败(RRC connection setup failure)、RRC恢复失败(RRC resume failure)等。终端设备可以根据过滤条件上报无线链路测量、接入性测量等测量。
ANR可以由终端设备辅助实现，是基站为了更好地做出各种测量、切换等决策，需要了解周边相邻小区的情况而设定的功能。简单来说，每个基站针对一个小区都会维护一张邻区关系表，根据终端设备上报的各种测量结果，对邻区关系表中的邻区进行增删。请参阅图15，图15是本发明实施例公开的一种ANR建立邻区关系的流程示意图。如图15所示，该ANR建立邻区关系可以包括以下步骤。
1、终端设备可以向小区A的基站上报包含测量的目标小区的PCI的测量报告。例如，该小区A可以为终端设备的服务小区，该基站可以为终端设备的服务基站。例如，PCI＝5可以代表目标小区，该PCI是局部标识，不具有全网唯一性。
2、在基站确定小区A的邻区关系表中无目标小区的PCI，或者基站确定对应频点下的该PCI是首次出现，或者，基站确定该PCI是未知的情况下，基站可以向终端设备发送小区全球标识(cell global identifier，CGI)请求消息。该CGI请求消息可以包含目标小区的PCI。该CGI请求消息用于指示终端设备读取目标小区的CGI，向基站上报目标小区的CGI。
3、终端设备读取目标小区的CGI。终端设备接收到来自基站的CGI请求消息之后，可以根据该CGI请求消息读取目标小区的CGI。例如，终端设备可以通过读取目标小区广播的系统消息块(system information block，SIB)1来得到目标小区的CGI。可选地，该CGI可以包括演进的小区全球标识(evolved cell global identifier，ECGI)或者新无线接入技术小区全球标识(NRcell global identifier，NCGI)。
4、终端设备向基站上报目标小区的CGI。例如，终端设备可以通过测量报告将目标小区的CGI发送给基站。
5、基站将目标小区添加到小区A的邻区关系表。基站接收到来自终端设备的目标小区的CGI之后，确定目标小区可以为小区A的领区，之后可以将目标小区添加到小区A的邻区关系表。
可以在上述步骤2中的CGI请求消息可以包括或携带过滤条件，一旦终端设备满足过滤条件，终端设备将不会读取目标小区的CGI和或不上报读取目标小区的CGI，即不发生步骤3-步骤5或步骤4-步骤5。
请参阅图16，图16是本发明实施例公开的另一种通信方法的流程示意图。其中，下面终端设备执行的步骤也可以由终端设备中的模块(例如，芯片)来执行，下面网络设备执行的步骤也可以由网络设备中的模块(例如，芯片)来执行。如图16所示，该通信方法可以包括以下步骤。
1601、网络设备确定终端设备的过滤条件。

网络设备可以根据终端设备能够获取的信息生成终端设备的过滤条件。终端设备能够获取的信息可以包括时间信息、地理位置信息、信号强度、终端设备的能力信息、终端设备的类型等中的一种或多种。信号强度可以为RSRP、RSRQ和信号与干扰加噪声比SINR中一种或多种的信号强度。终端设备的能力信息可以为能接入卫星网络的能力、支持MDT/SON特性的能力等。终端设备的类型可以为LTE/NR终端设备、物联网终端设备，车联网终端设备等。过滤条件可以包括以下的一项或多项：对特定时间或特定时间段不进行测量和/或上报；对特定地理位置不进行测量和/或上报；对特定事件不进行测量和/或上报；对特定小区不进行测量和/或上报；在终端设备处于节能状态的情况下，不进行测量和/或上报；在终端设备为物联网终端设备的情况下，不进行测量和/或上报；在终端设备的电量小于或等于阈值的情况下，不进行测量和/或上报。
其中，过滤条件中不同过滤条件的详细描述可以参考上面的描述，在此不加赘述。

相应地，终端设备接收到来自网络设备的过滤条件。
