  • the present application relates to the field of wireless communication technology, and in particular to a communication method, device and system, and computer-related products.

  • L1/L2triggered mobility, LTM layer 1 and/or layer 2 triggered mobility
  • the main idea of the LTM process is that the base station provides the UE with pre-configured information of one or more candidate cells based on the measurement report reported by the UE (for example, radio resource management (RRM) measurement report or layer 3 measurement report).
  • RRM radio resource management
  • the UE After receiving the pre-configured information from the base station, the UE sends a measurement report (for example, layer 1 measurement report) to the base station, and the source DU decides to trigger the LTM switching based on the measurement report reported by the UE.
  • the source DU sends an LTM handover command to the UE through layer 1 signaling and/or layer 2 signaling, so that the UE performs a handover process based on an instruction in the handover command.
  • the base station may first handover the UE from cell 1 to cell 2 based on the layer 1 measurement results. Then, the base station may also determine that the signal quality of cell 1 is higher than the signal quality of cell 2 based on the RRM measurement results, and handover the UE from cell 2 back to cell 1, resulting in frequent ping-pong handovers.

本申请涉及无线通信技术领域，尤其涉及一种通信方法、装置和系统，以及计算机相关产品。
背景技术
在无线通信系统中，移动性管理是通过变更用户设备(user equipment，UE)的服务小区，使UE无论在网络覆盖范围内如何移动，都可以享受网络服务。为了保证UE通信的连续性，连接态的移动性是通过切换完成的。
目前，第五代移动通信技术(5th-generation，5G)无线接入网(radio access network，RAN)架构考虑基站采用集中单元(centralized unit，CU)和分布单元(distributed unit，DU)独立部署的方式，以更好地满足各场景和应用的需求。在CU-DU分离的基站部署下，为了减少切换时延，进一步增强业务连续性，5G系统考虑采用基于低层的切换，基于低层的切换可以通过层1和/或层2触发的移动性(L1/L2triggered mobility，LTM)过程实现。LTM过程的主要思想为：基站基于UE上报的测量报告(例如，无线资源管理(radio resource management，RRM)测量报告或层3测量报告)为UE提供一个或多个候选小区的预配置信息。UE接收到来自基站的预配置信息后，向基站发送测量报告(例如，层1测量报告)，源DU基于UE上报的测量报告决定触发LTM切换。源DU通过层1信令和/或层2信令向UE发送LTM切换命令，以使UE基于该切换命令中的指示执行切换过程。
然而，对于配置为LTM的小区，如果UE既进行层1测量，上报层1测量结果，也会进行RRM测量，上报RRM的测量结果报告，可能导致频繁切换，影响LTM切换性能。例如，基站可以基于层1测量结果先将UE从小区1切换到小区2。然后基站还可以基于RRM的测量结果确定小区1的信号质量高于小区2的信号质量，将UE从小区2切换回小区1，导致了频繁的乒乓切换。
发明内容
本申请实施例提供一种通信方法、装置和系统，以及计算机相关产品，可以减少不必要的测量或者测量结果的上报，节省了功耗。
第一方面，本申请提供了第一种通信方法，该方法可以应用于终端设备，也可以应用于终端设备中的装置(例如，芯片，或者芯片系统，或者电路)，或者是能够和终端设备匹配使用的装置，下面以应用于终端设备为例进行描述。
该方法可以包括：终端设备接收来自网络设备的第一配置；终端设备接收来自网络设备的第二配置；如果根据测量对象配置检测到的第一小区是LTM候选小区，终端设备针对第一小区不执行第一行为；和/或如果根据测量对象配置检测到的第一小区不是LTM候选小区，终端设备针对第一小区执行第一行为。
其中，第一配置包括LTM候选小区的信息，该LTM候选小区可以由网络设备根据终端设备上报的测量报告(例如，层3测量报告等)进行确定得到的。本申请对于LTM候选小区的数量和LTM候选小区的信息不做限定，LTM候选小区的数量可以为一个或多个。LTM候选小区的信息可以包括LTM候选小区的物理小区标识(physical cell identities，PCI)，还可以包括LTM候选小区的配置信息。
第二配置包括第一测量配置，第一测量配置包括测量对象配置。本申请对于第一测量的类型和第一测量配置的内容不做限定，在一些可能的实现方式中，第一测量可以包括层3测量或无线资源管理(radio resource management，RRM)测量。第一测量配置可以包括测量对象配置，测量对象配置可以包括测量对象的参数，例如，测量对象的频点信息，从而终端设备可以基于频点信息扫描待测量的测量对象(小区)的测量结果。
第一行为包括以下至少一项：第一测量、第一测量的测量报告的上报。可选的，第一测量为层3测量，第一测量的测量报告可以为层3测量报告。第一测量为RRM测量，第一测量的测量报告可以为RRM测量报告。终端设备针对第一小区不执行第一行为可以理解为终端设备执行第一行为不适用于第一小区中的LTM 候选小区。如果终端设备检测到的第一小区是LTM候选小区之后，终端设备可以不对该第一小区的PCI进行相关，从而不会执行第一测量，也不会上报第一测量的测量结果。
在本申请提供的方案中，终端设备接收来自网络设备的第一配置和第二配置，如果根据第二配置中测量对象配置检测到的第一小区是LTM候选小区，则终端设备针对该第一小区不执行第一行为，从而可以不对LTM候选小区进行第一测量，或者还可以不上报针对LTM候选小区第一测量的测量结果，可以减少不必要的测量，节省了功耗，进一步减少切换冲突，可以避免频繁切换，提高LTM切换性能。如果根据第二配置中测量对象配置检测到的第一小区不是LTM候选小区，则可以针对该第一小区执行第一行为，从而可以对非LTM候选小区进行第一测量，还可以上报非LTM候选小区的第一测量的测量结果。网络设备可以基于这些上报的小区的测量结果触发层3切换，提高了切换性能，利于提高终端设备的通信质量。此外，相对于现有技术而言，没有针对基于测量对象检测到的小区中的LTM候选小区执行第一测量，也没有上报该LTM候选小区的第一测量的测量报告，仅对于不属于LTM候选小区的第一小区执行第一行为，可以减少测量，节省了功耗，减少测量上报的空口开销，可以避免频繁切换，可以避免频繁的乒乓切换，提高了LTM切换性能。
在一些可能的实现方式中，第一配置还可以包括第一信息或第二信息。其中，第一信息和第二信息可以包含于同一指示中。例如，第一信息和第二信息中的一个包含于第一指示中，第一指示为1比特的指示信息，第一指示的取值可以为0或1，当第一指示的取值为0时表示第一指示用于指示第一信息，当第一指示的取值为1时表示第一指示用于指示第二信息；或当第一指示的取值为1时表示第一指示用于指示第一信息，当第一指示的取值为0时表示第一指示用于指示第二信息。第一指示或者可以为true或false，当第一指示的取值为true时表示第一指示用于指示第一信息，当第一指示的取值为flase时表示第一指示用于指示第二信息；或第一指示的取值为false时表示第一指示用于指示第一信息，当第一指示的取值为true时表示第一指示用于指示第二信息等。
第一信息和第二信息或者可以包含于不同的指示中。例如，第一信息为一个字段，第二信息为第二字段，如果网络设备配置了第一字段，则终端设备可以执行第一信息指示的行为，如果网络设备配置了第二字段，则终端设备可以执行第二信息指示的行为。
第一信息用于指示：如果第一小区不是LTM候选小区，针对第一小区执行第一行为；和/或如果第一小区是LTM候选小区，针对第一小区不执行第一行为。也就是说，第一信息用于指示终端设备对于不是LTM候选小区的第一小区执行第一行为，或者还用于指示终端设备对于是LTM候选小区的第一小区不执行第一行为。可以理解为第一信息用于指示终端设备执行第一方面中接收到第一配置和第二配置之后的步骤。
第二信息用于指示针对第一小区执行第一行为。也就是说，无论第一小区是否为LTM候选小区，都需针对第一小区执行第一行为。可以理解为第二信息用于指示终端设备不执行第一方面中接收到第一配置和第二配置之后，还可以理解为终端设备按照现有方法执行第一行为。通过执行第一信息，相对于执行现有技术中的第二信息而言，没有针对基于测量对象检测到的小区中的LTM候选小区执行第一行为，可以减少不必要的测量，节省了功耗，进一步可以避免频繁的乒乓切换，提高了LTM切换性能。
在一些可能的实现方式中，第一配置还可以包括第二测量配置，该通信方法还可以包括：终端设备根据第二测量配置执行第二测量。其中，第二测量配置可以理解为针对第二测量的配置信息。本申请对于第二测量的类型和第二测量配置的内容不做限定，在一些可能的实现方式中，第二测量可以包括以下至少一项：层1测量、SSB测量、CSI-RS测量。第二测量配置可以包括以下一项或多项：测量周期、测量资源(例如，SSB或CSI-RS)、测量量配置、测量间隔、测量标识、S测量配置。
可以理解，在第一配置还包括第二测量配置的情况下，可以根据第二测量配置执行第二测量，还可以上报第二测量的测量结果，以使得网络设备基于第二测量的测量结果进行切换决策，在确认切换之后，终端设备可以执行LTM切换过程，提高了切换效率。
在一些可能的实现方式中，终端设备针对第一小区执行第一行为包括：终端设备根据第一测量配置针对第一小区执行第一行为。其中，第一测量配置还可以包括以下至少一项：测量标识、上报配置、测量量配置、测量间隔配置以及S配置等参数。可以理解，根据第一测量配置中的这些参数执行第一行为，可提高执行第一行为的准确率，利于提高切换性能。
在一些可能的实现方式中，终端设备针对第一小区执行第一行为包括：如果测量周期的定时器超时或测量事件满足测量上报触发条件，针对第一小区上报执一测量的测量结果。如此，可以在测量周期的定时器超时或测量事件满足测量上报触发条件时，对于非LTM候选小区的第一测量的测量结果进行上报，网络设备可以基于这些上报的小区的测量结果触发层3切换，保证切换的性能。
第二方面，本申请提供了第二种通信方法，该方法可以应用于终端设备，也可以应用于终端设备中的装置(例如，芯片，或者芯片系统，或者电路)，或者是能够和终端设备匹配使用的装置，下面以应用于终端设备为例进行描述。该方法可以包括：终端设备接收来自网络设备的第三配置；终端设备接收来自网络设备的第二配置；如果根据测量对象配置检测到的第一小区是第一列表中的小区，终端设备针对第一小区不执行第一行为；和/或如果根据测量对象配置检测到的第一小区不是第一列表中的小区，终端设备针对第一小区执行第一行为。
其中，第三配置包括第一列表，第一列表包括至少一个小区。第三配置和第一配置可以包含于相同的消息中，或者第三配置和第一配置可以包含于不同的消息中。第一列表中的小区不执行第一行为，第一行为包括第一测量和/或第一测量的测量结果的上报。第一列表中的小区包括LTM候选小区。此处的LTM候选小区可以为全部的LTM候选小区，或者可以包括部分的LTM候选小区。在一种示例中，第一列表中的小区包括部分候选小区。可以理解，上报部分小区的第一测量的测量结果，可以节省功耗和空口资源。
可以理解，网络设备可以通过列表配置终端设备不执行第一行为的小区，通过网络配置的方式，提高了配置的灵活性。终端设备根据第一测量配置及网络配置的第一列表执行第一行为，针对部分LTM候选小区不执行第一行为，减少了终端设备的测量功耗，节省了测量上报的空口资源。此外，在一些网络部署中，网络设备需要进行载波管理或LTM候选小区管理等功能，还可以配置不属于第一列表的LTM候选小区，以使终端设备对这些不属于第一列表的LTM候选小区执行第一测量，实现了小区管理或载波管理功能。
在一些可能的实现方式中，终端设备针对第一小区执行第一行为包括：终端设备根据第一测量配置针对第一小区执行第一行为。其中，第一测量配置还可以包括以下至少一项：测量标识、上报配置、测量量配置、测量间隔配置以及S配置等参数。可以理解，根据第一测量配置中的这些参数执行第一行为，可提高执行第一行为的准确率，利于提高切换性能。
在一些可能的实现方式中，终端设备针对第一小区执行第一行为包括：如果测量周期的定时器超时或测量事件满足测量上报触发条件，针对第一小区上报执一测量的测量结果。如此，可以在测量周期的定时器超时或测量事件满足测量上报触发条件时，对于非LTM候选小区的第一测量的测量结果进行上报，网络设备可以基于这些上报的小区的测量结果触发层3切换，保证切换的性能。
第三方面，本申请提供了第三种通信方法，该方法可以应用于终端设备，也可以应用于终端设备中的装置(例如，芯片，或者芯片系统，或者电路)，或者是能够和终端设备匹配使用的装置，下面以应用于终端设备为例进行描述。该方法可以包括：终端设备接收来自网络设备的第四配置。
其中，第四配置包括第三信息，第三信息指示允许或禁止测量结果上报的测量事件类型。第四配置可以为第一配置中的信息，或者可以为与第一配置不同的信息。本申请对于允许或禁止测量结果上报的测量事件类型不做限定，可以为测量事件的测量事件类型。例如，允许测量结果上报的测量事件类型为A1测量事件的测量事件类型，禁止测量结果上报的测量事件类型为A3测量事件的测量事件类型等。如此，在A1测量事件的测量结果满足A1测量事件的测量上报触发条件时，在A3测量事件的触发条件满足A3测量事件的测量上报触发条件时，也不上报A3测量事件得到的测量结果。
可以理解，终端设备接收来自网络设备的第四配置，根据第四配置中的第三信息确定允许或禁止测量结果上报的测量事件类型，从而终端设备可以基于每个事件类型上报或不上报该测量事件相关的结果，可以减少基于每个事件的测量结果的上报，节省了功耗和空口资源。例如，如果网络设备将A3事件包含在指示禁止测量结果上报的第二列表中，则UE基于第二列表不上报A3事件的测量结果，网络设备没有收到A3事件的测量结果，从而不会基于A3事件进行切换判决，这样就避免了层1和层3切换的冲突，避免了频繁的乒乓切换，可提高LTM切换性能。
在一些可能的实现方式中，第三信息可以包括第二列表，该第二列表包括至少一种测量事件类型。若第二列表包括的测量事件类型为允许测量结果上报的测量事件类型，则第三信息用于指示允许测量结果上报的测量事件类型。若第二列表包括的测量事件类型为禁止测量结果上报的测量事件类型，则第三信息用于指示禁止测量结果上报的测量事件类型。可以理解，通过列表配置允许或禁止测量结果上报的测量事件类型，可节省配置资源。
在一些可能的实现方式中，还可以包括以下步骤：网络设备向终端设备发送第二配置；如果根据测量对象配置检测到的第一小区是LTM候选小区，当第一小区的测量结果满足允许测量结果上报的测量事件类型的测量上报触发条件时，上报测量结果；和/或如果根据测量对象配置检测到的第一小区是LTM候选小区，当第一小区的测量事件类型满足禁止测量结果上报的测量事件类型时，不上报测量结果。
其中，第二配置包括第一测量配置，该第一测量配置包括测量对象配置。在一些可能的示例中，还可 以包括：网络设备向终端设备发送第一配置。可以理解，终端设备根据来自网络设备的第二配置中的测量对象配置检测第一小区，如果第一小区是LTM候选小区，第一小区的测量结果满足允许测量结果上报的测量事件类型的测量上报触发条件时，可以上报该测量结果。在第一小区是LTM候选小区，但第一小区的测量事件类型是禁止测量结果上报的测量事件类型时，即使第一小区的测量结果满足测量上报触发条件，也不上报该测量报告。如此，通过测量事件类型和测量上报触发条件筛选待上报的测量结果，可以避免不必要的测量上报，可节省功耗和空口资源，利于提高切换性能。可选的，针对第一小区中的非LTM候选小区的测量结果，可以上报。或者可以在非LTM候选小区的测量结果满足预设的测量上报触发条件时进行上报。
在一些可能的实现方式中，第一测量配置还可以包括第一测量周期，该通信方法还可以包括以下步骤：网络设备向终端设备发送第五配置；如果第一小区是LTM候选小区，基于第二测量周期针对第一小区执行第一测量；或如果第一小区不是LTM候选小区，基于第一测量周期针对第一小区执行第一测量。
其中，第二测量周期大于第一测量周期。第一测量周期适用于根据测量对象配置检测到的第一小区中的非LTM候选小区，第二测量周期适用于第一小区中的LTM候选小区。也就是说，在第一小区是非LTM候选小区时，可以基于第一测量周期针对第一小区执行第一测量。而在第一小区是LTM候选小区时，可以基于第二测量周期针对第一小区执行第一测量。如此，LTM候选小区的测量周期(或测量窗)可以大于非LTM候选小区的测量周期，以减小针对LTM候选小区的第一测量，从而减少测量结果的上报，可以节省功耗和空口资源，利于提高LTM切换性能。
第四方面，本申请提供了第四种通信方法，该方法可以应用于终端设备，也可以应用于终端设备中的装置(例如，芯片，或者芯片系统，或者电路)，或者是能够和终端设备匹配使用的装置，下面以应用于终端设备为例进行描述。该方法可以包括：终端设备接收来自网络设备的第二配置；终端设备接收来自网络设备的第五配置；如果根据测量对象配置检测到的第一小区是LTM候选小区，终端设备基于第二测量周期针对第一小区执行第一测量；和/或如果根据测量对象配置检测到的第一小区不是LTM候选小区，终端设备基于第一测量周期针对第一小区执行第一测量。
其中，第二配置包括第一测量配置，第一测量配置包括测量对象配置和第一测量周期。第五配置包括第二测量周期，第二测量周期大于第一测量周期。第一测量周期适用于根据测量对象配置检测到的第一小区中的非LTM候选小区，第二测量周期适用于第一小区中的LTM候选小区。可以理解，终端设备接收来自网络设备发送的第二配置和第五配置，可以根据第二配置中的测量对象配置确定第一小区，在第一小区是非LTM候选小区时，基于第一测量周期针对第一小区执行第一测量。或者还可以在第一小区是LTM候选小区时，可以基于第二测量周期针对第一小区执行第一测量。如此，LTM候选小区的测量周期(或测量窗)可以大于非LTM候选小区的测量周期，以减小针对LTM候选小区的第一测量，从而减少测量结果的上报，可以节省功耗和空口资源，利于提高LTM切换性能。
第五方面，本申请提供了第五种通信方法，该方法可以应用于网络设备，也可以应用于网络设备中的装置(例如，芯片，或者芯片系统，或者电路)，或者是能够和网络设备匹配使用的装置，下面以应用于网络设备为例进行描述。该方法可以包括：网络设备向终端设备发送第三配置；其中，第三配置包括第一列表，第一列表包括至少一个小区，第一列表中的小区不执行第一行为，第一行为包括以下至少一项：第一测量、第一测量的测量结果的上报。

为了便于理解本申请实施例，下面先给出本申请实施例可能出现的技术术语的定义。本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。
(1)测量，可以分为波束级测量和小区级测量。其中，波束级测量是指网络可以配置UE测量和上报小区的一个或多个波束相关的信息，例如，波束标识和/或波束测量结果。小区级测量是指UE按照网络的配置，通过测量某小区的一个或多个波束，对测量的结果(例如，功率值)将进行平均化处理以获取该小区测量结果。在连接态下，在物理层获得波束质量之后，可以进行层1滤波。在层1滤波之后，在RRC层上通过多个波束获得小区质量，可以进行层3滤波。
(a)层1测量：
层1测量通常是指波束级测量。波束级测量包括以下至少一项：同步信号和物理广播信道(physical boardcast channel，PBCH)块(synchronization signal and PBCH block，SSB)测量、信道状态信息参考信号(channel state information-reference signal，CSI-RS)。其中，SSB可以由主同步信号(primary synchronization signals，PSS)、辅同步信号(secondary synchronization signals，SSS)和PBCH三部分共同组成。
(b)层3测量：
在某些情况下，层3测量是指无线资源管理(radio resource management，RRM)测量。在一些情况下，层3测量是小区级测量。在某些情况下，RRM测量可以理解为层3测量。
(c)测量事件：
测量事件可以包括以下至少一项：A1测量事件、A2测量事件、A3测量事件、A4测量事件、A5测量事件、B1测量事件和B2测量事件。其中，A1测量事件的触发条件是服务小区的信号质量高于阈值。可选的，A1测量事件可以用于关闭某些小区的测量功能。A2测量事件的触发条件是服务小区的信号质量低于阈值。可选的，通常A2测量事件发生之后可能会发生切换等操作，可以用于开启满足触发条件的小区的测量功能。A3测量事件的触发条件是同频/异频邻区的质量比服务小区的质量高于一个偏移量，可选的，A3测量事件可以用于决定终端设备是否切换到邻区。A4测量事件的触发条件是邻区的质量高于阈值。A5测量事件的触发条件是服务小区的质量低于一个阈值，且邻区的质量高于一个阈值。A6测量事件的触发条件是邻小区比服务小区(例如scell)高于一个偏移量。B1测量事件的触发条件是异系统邻小区质量高于服务小区的门限。B2测量事件的触发条件是服务小区质量低于门限1，且异系统邻小区质量高于门限2。本申请对于测量事件、上述的测量事件中涉及的各个阈值(门限)的大小和上报测量事件的测量结果的测量上报触发条件不做限定。测量上报触发可以是周期性触发或事件型触发。
(2)切换，是为了保证业务连续，处于RRC连接态的UE在移动过程中发生的服务小区的变更，还可以称为移动性。请参阅图4，图4是本申请实施例提供的一种切换方法的流程示意图。一种可能的实现方式，切换可以通过层3(RRC层)来控制完成的。如图4所示，切换方法可以包括如下步骤S400至步骤S408，其中：
步骤S400：源基站向UE发送测量配置。
可选的，该测量配置为层3测量。层3测量配置可以由CU生成，其中，层3测量配置可以通过measConfig配置给UE。层3测量配置可以包括以下参数：测量对象(measurement objective，MO)、上报配置(reporting configuration)、测量标识(measurement identities)、测量量配置(quantity configuration)、测量间隔配置(measurement gap)和S测量(S-Measure)，其中：
1、MO参数可提供一个对象列表，UE需要对该对象列表的对象执行测量。层3测量可以是per MO粒度执行的。也就是说，对于该MO关联的频点，该频点上的所有小区的L3测量配置是相同的。对于NR MO，UE测量并上报服务小区，列出的小区和/或检测到的小区的测量结果。
网络设备可能会给一个MO配置包括如下3类列表，其中：
第一类，小区相关的列表，该列表中可以包含小区标识和用于事件触发型上报的小区特定的偏移量。
第二类，黑名单小区列表(blacklisted cell)，黑名单列表内的小区不能用于事件评估或者测量上报。
第三类，白名单小区列表(whitelisted cell)，白名单内的小区是事件评估或者测量上报时仅可使用的小区。
2、上报配置参数可提供一个上报配置列表，每个MO可以有一个或多个上报配置。每一个上报配置中包括触发UE发送测量报告的上报准则、UE可用于波束和小区测量的参考信号(reference signal，RS)类型、上报格式。
其中，触发UE发送测量报告的上报准则，该上报准则可以是周期性触发，或者可以是单一事件触发。例如，触发的事件可以满足前述的测量事件的触发条件。该上报准则或者可以是全球小区标识(cell global identifier，CGI)报告(reportCGI)或系统帧号(system frame number，SFN)与帧边界定时差报告(SFN and frame timing difference，reportSFTD)。reportCGI用于检测小区的CGI。reportSFTD用于检测主小区(primary  cell，PCell)和目标小区之间的SFN与帧边界定时差结果。
RS类型可以包括SSB或CSI-RS等。
上报格式用于指示UE在测量报告中包含的每小区和每波束的测量量类型(例如，RSRP、参考信号接收质量(reference signal received quality，RSRQ)等)，以及其他相关信息(例如，可上报的最大小区数量和每小区上的最大波束数量等)。
3、测量标识参数提供一个测量标识列表，其中，每一测量标识都与带有一种上报配置的一个MO相关联。通过配置多个测量标识，可以实现将多个MO关联到同一上报配置，或者可以将多种上报配置关联到同一MO。UE会在触发上报的测量报告中，包含相应的测量标识，作为给网络的一个参考。
4、测量量配置参数定义了事件触发型和周期性上报型测量的测量滤波配置。
5、测量间隔配置参数表示UE可能用于执行测量的时间段。
6、S测量参数提供了NR服务小区SpCell质量的门限控制，可以包含一个与NR SpCell质量相关的门限阈值。例如，在配置了S测量之后，当SpCell的质量低于设置的门限值时，UE才会开启对非服务小区的测量。
步骤S401：UE向源基站发送测量报告。
可选的，步骤S401中的测量报告为层3测量报告或层3测量结果。层3测量报告可以包括服务小区以及邻区的信号质量。
步骤S402：源基站执行切换判决。
源基站可以基于层3测量报告的测量结果和/或自身的切换算法进行切换判决。例如，源小区的信号质量较差，但是目标小区的信号质量较好，基站可以决定触发切换。
步骤S403：源基站向目标基站发送切换请求。
若源基站决定触发切换，源基站向目标小区发送切换请求。该切换请求中可以包括目标小区标识(identifier，ID)、密钥、UE在源小区的ID、接入层的配置等。
步骤S404：目标基站执行准入控制。
准入控制可以由目标基站执行。如果切片信息被发送到目标基站，则应执行切片感知准入控制。如果协议数据单元(protocol data unit，PDU)会话与不支持的切片关联，目标基站应拒绝此类PDU会话。
步骤S405：目标基站向源基站发送切换请求确认消息。
其中，切换请求确认消息可以以RRC容器(RRC container)的方式包含在确认消息中。
步骤S406：源基站向UE发送切换命令。
其中，切换命令可以通过RRC重配消息进行发送，该切换命令中可以包含了接入目标小区需要的信息，至少包括目标小区标识、新的UE ID、目标基站的安全算法标识，还有可能携带接入目标小区的专用随机接入信道(random access channel，RACH)资源等。
可选的，UE接收到切换命令后，断开与源小区的连接。
步骤S407：UE与目标基站执行同步过程。
其中，同步过程可以通过RACH过程实现，以接入到目标小区，后续UE可以与目标小区进行数据的传输。
步骤S408：UE向目标小区发送RRC重配完成消息。
其中，RRC重配完成消息可以用于确认成功完成RRC重配过程。
(3)层1和/或层2(Layer1/Layer2，L1/L2)切换，是为了降低切换时延和中断时间，提高终端设备的用户体验和业务的连续性的一种切换方法。L1/L2切换可通过L1信令(如下行控制信息(downlink control information，DCI))和/或L2信令(如媒体访问控制层控制单元(medium access control control element，MAC CE))来触发终端设备执行切换。
L1/L2切换还可以称为低层切换，或层1和/或层2触发的移动性(L1/L2triggered mobility，LTM)或低层触发的切换。LTM过程的主要思想为：基站基于UE上报的测量报告(例如，RRM测量报告或层3(Layer 3，L3)测量报告)配置一个或多个候选小区，并通过RRC消息向UE提供一个或多个候选小区(可称为LTM候选小区)的预配置信息。UE在接收到来自基站的预配置信息后，向基站发送测量报告(例如，层1测量报告)，源DU基于UE上报的测量报告决定触发LTM切换。源DU通过层1信令和/或层2信令向UE发送LTM切换命令，以使UE执行切换过程。
LTM过程是可以是在同一CU内的切换过程。LTM过程包括多种切换场景，以下示例性的列举如下几种，其中：
场景一：CU内DU间(intra-CU inter-DU)的LTM过程。
请参阅图5，图5是本申请实施例提供的一种CU内DU间LTM过程的流程示意图，该LTM切换过程中的源DU和目标DU是不同的DU。如图5所示，CU内DU间L1/L2切换方法可以包括以下步骤S500至步骤S511，其中：

可选的，该测量配置可以为层3测量配置，可参照步骤S400的描述，在此不再赘述。
步骤S501：UE上报第一测量报告。
可选的，UE向CU上报第一测量报告。其中，第一测量报告可以为层3测量报告。第一测量报告中的测量结果可以根据步骤S500中的测量配置进行测量得到。
步骤S502：CU进行切换决策。
步骤S503：CU向DU发送UE上下文建立请求。
如果CU决定执行LTM过程，CU向属于一个或多个候选DU的一个或多个候选小区请求LTM。CU可以向候选小区发送UE上下文建立请求消息，或者可以发送LTM请求消息。可选的，CU可以参考UE上报的测量报告和/或自身切换算法确定添加的候选小区。
步骤S504：候选DU执行准入控制。
步骤S505：候选DU向CU发送UE上下文请求确认消息。
如果候选DU决定添加LTM候选小区，则候选DU可以向CU发送UE上下文建立请求确认消息，或者LTM请求确认消息。其中，UE上下文建立请求确认消息可以包括候选小区的配置信息。
步骤S506：CU向UE发送RRC重配消息。
其中，RRC重配消息包括LTM配置信息。LTM配置信息还可以称为L1/L2切换(预)配置信息或LTM候选小区配置信息等。LTM配置信息可以包含一个或多个候选小区(本文中可称为LTM候选小区)的(预)配置信息。可选的，候选小区的配置信息是通过小区组配置或RRC重配进行配置的。可选的，RRC重配消息还可以包括源小区的配置信息，或者可以包括L1测量配置或层1测量上报配置。UE在接收到RRC重配消息后没有断开与源小区的连接。
步骤S507：UE发送RRC重配完成消息。
可选的，UE向CU发送RRC重配完成消息。其中，RRC重配完成消息可以发送给源DU中的源小区。该RRC重配完成用于指已经成功接收到RRC重配消息。
步骤S508：UE上报第二测量报告。
可选的，UE向源DU发送第二测量报告。其中，第二测量报告可以包括L1测量报告，第二测量报告可以基于步骤S506中的L1测量配置进行测量得到。
步骤S509：源DU向UE发送切换命令。
其中，源DU可以基于UE上报的第二测量结果进行切换决策。如果源DU决定触发LTM过程，可以向UE发送切换命令。相应地，UE接收来自源DU的切换命令。该切换命令可以为LTM切换命令，或者称为L1/L2切换命令，或者称为LMT小区切换命令，在此仅作为示例不对名称进行限制。该切换命令可以承载在MAC层信令(MAC CE)或物理层信令(DCI)。LTM切换命令用于指示UE切换的目标小区的信息，例如目标小区索引，或目标小区PCI，(目标小区可以包含在上述的候选小区中)，或者指示了目标小区的配置信息。可选的，LTM切换命令中还可以包含波束信息。
步骤S510：UE向目标小区执行接入过程。
可选的，UE与目标DU执行同步过程。同步过程可以通过RACH过程实现。
接入过程可以通过RACH过程实现，或通过RACH-less实现。比如，UE收到切换命令后，向目标小区执行随机接入过程，或者UE如果在接收切换命令前已经获取了定时提前，则UE在接收到切换命令后在预配置的资源上向目标小区发送切换完成确认。UE可以基于L1/L2切换命令中指示的目标小区，向目标小区所在的目标DU发起接入，后续UE可以与目标小区进行数据的传输。
可选的，步骤S511：UE向目标DU发送切换完成消息。
其中，切换完成消息可以发送给L1/L2切换命令中指示的目标小区。
场景二：CU内DU内(intra-CU intra-DU)的LTM过程。
请参阅图6，图6是本申请实施例提供的一种CU内DU内的LTM过程的流程示意图，该LTM切换过程中的源DU和目标DU是同一个DU。如图6所示，CU内DU内L1/L2切换方法可以包括以下步骤S600至步骤S610，其中：
步骤S600：CU向UE发送测量配置。
其中，测量配置可以为层3测量配置，可参照步骤S400的描述，在此不再赘述。
步骤S601：UE上报第一测量报告。
可选的，UE向CU发送第一测量报告。
其中，第一测量报告可以为层3测量报告。第一测量报告中的测量结果可以根据步骤S600中的测量配置进行测量得到。

步骤S603：DU执行准入控制。
若DU允许UE接入，则可以执行步骤S604：DU向CU发送UE上下文修改请求确认消息。可选的，DU向CU发送LTM请求确认消息。UE上下文修改请求确认消息可以包括候选小区的配置信息。

其中，步骤S603至步骤S610可分别参照图5中的步骤S504和步骤S511的描述，在此不再赘述。
对于配置为LTM候选小区的小区，UE需要对这些小区执行层1测量。如果UE还需要对这些小区进行层3测量，由于层1测量是波束级的测量结果，而层3测量是小区级的测量结果，UE上报包含测量结果的测量报告，网络基于层1测量报告和层3测量报告触发切换的目标小区可能会不同，导致频繁切换，影响LTM切换性能。例如，基站可以基于层1测量结果先将UE从小区1切换到小区2。然后基站还可以基于层3的测量结果确定小区1的信号质量高于小区2的信号质量，从而通过层3切换将UE从小区2切换回小区1，导致了频繁的乒乓切换。此外，如果网络不会针对LTM的小区的测量结果触发层3切换，则UE上报层3的测量结果对网络来说可能是没用的，UE发送这些小区相关的层3测量报告会报告浪费了空口资源，网络处理这些层3的测量报告会增加了基站的处理负担。
基于上述，本申请提出一种通信方法，下面将分别通过如下各实施例进行描述。这些通信方法有些仅针对小区切换中的部分流程，有些可以应用于小区切换中的任意一个或多个流程。应理解的是，这些通信方法可以相互结合使用，比如，可以是小区切换中的某一流程使用一种方法而另一流程使用另一种方法，还可以是小区切换中的某一流程既使用一种方法又使用另一种方法。
应理解的是，小区切换有可能会随着技术方案的演进而发生变化，本申请提供的技术方案并不限于下面描述的过程。进一步地，本申请实施例中对场景的描述仅为举例，并不限定本申请实施例的方案仅能运用为描述场景中，同样适用于存在类似问题的场景等。

第一测量还可以包括测量标识、上报配置、测量量配置、测量间隔配置和S测量配置等参数。其中，上报配置可以包括待上报的测量事件的配置信息，测量事件可以包括前述的A1测量事件至A6测量事件、B1测量事件和B2测量事件等。测量事件的上报类型可以包括周期型上报和事件型上报，其中，周期型上报是指在测量周期的定时器超时的情况下，终端设备触发测量上报。定时器可基于预先为测量周期设置的时间阈值进行计时或倒计时，在计时时间为时间阈值时或倒计时时间为0时，确认测量周期的定时器超时。事件型上报是指在测量结果满足测量事件的测量上报触发条件时，终端设备上报测量结果。事件型上报的测量上报事件可以包括以下至少一项：A1测量事件、A2测量事件、A3测量事件、A4测量事件、A5测量事件、B1测量事件、B2测量事件。
以A1测量事件进行举例说明，A1测量事件的触发条件是服务小区的信号质量高于信号质量阈值，测量上报触发条件为满足A1测量事件的触发条件，且持续时长超过时间阈值。如果小区A的信号质量高于信号质量阈值的持续时长超过时间阈值，则上报小区A的测量结果。如果小区A的信号质量高于信号质量阈值的持续时长且未超过时间阈值，则不上报小区A的测量结果。在上报小区A的测量结果之前，可以将小区A的测量结果添加至触发小区列表。在上报小区A的测量结果之后，如果小区A的信号质量低于信号质量阈值的持续时长超过时间阈值，则可以将触发小区列表中的小区A进行删除。
可选的，测量上报触发条件可以包括前述的各类测量上报事件的触发条件，还可以包括其他的触发条件，例如，第一测量配置中测量对象是否为预设对象，具体可以为测量小区是否为LTM候选小区；测量小区的触发事件是否为目标事件；针对不同小区定义的测量周期等，本申请对此不做限定。
步骤S703：如果根据测量对象配置检测到的第一小区是LTM候选小区，终端设备针对第一小区不执行第一行为。
其中，第一行为包括以下至少一项：第一测量、第一测量的测量报告的上报。可选的，第一测量为层3测量，第一测量的测量报告可以为层3测量报告。第一测量为RRM测量，第一测量的测量报告可以为RRM测量报告。
终端设备可以根据测量对象配置中的相关参数检测第一小区，例如，终端设备根据步骤S702中测量对象配置中的频点信息检测第一小区，终端设备根据步骤S701中配置的LTM候选小区的信息确定第一小区是否为LTM候选小区。第一测量和第一测量的上报配置可参照步骤S702的描述，在此不再赘述。终端设备针对第一小区不执行第一行为可以理解为该第一行为不适用于第一小区中的LTM候选小区。在一种终端设备的实现方式中，如果终端设备检测到的第一小区是LTM候选小区，终端设备可以不对该第一小区的PCI进行相关，从而不会执行第一测量，也不会上报第一测量的测量结果。
在图7所示的通信方法中，终端设备接收来自网络设备的第一配置和第二配置，如果根据第二配置中测量对象配置检测到的第一小区是LTM候选小区，则终端设备针对该第一小区不执行第一行为。如此，对于LTM候选小区，可以不执行第一行为，从而可以不对LTM候选小区进行第一测量，或者还可以不上报针对LTM候选小区第一测量的测量结果，可以避免频繁切换，可提高LTM切换性能。
结合图7的实施例，请参阅图8，图8是本申请实施例提供的第二种通信方法的流程示意图。应理解，本申请中不同实施例的术语解释可以互相参考，为避免描述冗余，不同实施例可以不对同一术语赘述。如图8所示，该通信方法可以包括S801至步骤S803，其中：
步骤S801：网络设备向终端设备发送第一配置；其中，第一配置包括LTM候选小区的信息。
相应地，终端设备接收来自网络设备的第一配置。
步骤S802：网络设备向终端设备发送第二配置；其中，第二配置包括第一测量配置，第一测量配置包括测量对象配置。
相应地，终端设备接收来自网络设备的第二配置。
步骤S803：如果根据测量对象配置检测到的第一小区不是LTM候选小区，终端设备针对第一小区执行第一行为。
其中，第一行为包括以下至少一项：第一测量、第一测量的测量报告的上报。步骤S801可以参照步骤S701的描述，步骤S802可以参照步骤S702的描述，在此不再赘述。在本申请实施例中，对于不是LTM候选小区的小区，可以称为非LTM候选小区，但不对此构成限定。
在图8所示的通信方法中，终端设备接收来自网络设备的第一配置和第二配置，如果根据第二配置中测量对象配置检测到的第一小区不是LTM候选小区，则可以针对该第一小区执行第一行为。如此，对于配置为非LTM候选小区，可以执行第一行为，从而可以对非LTM候选小区进行第一测量，还可以上报非LTM候选小区的第一测量的测量结果，网络设备可以基于这些上报的小区的测量结果触发层3切换，提高了切换性能，利于提高终端设备的通信质量。此外，相对于现有技术而言，没有针对基于测量对象检测到的小区中的LTM候选小区执行第一测量，也没有上报候选小区的第一测量的测量报告，仅对于不属于LTM候选小区的第一小区执行第一行为，可以避免频繁的乒乓切换，提高了LTM切换性能。
在一些可行的示例中，在步骤S802之后，还可以包括：如果根据测量对象配置检测到的第一小区是LTM候选小区，终端设备针对第一小区不执行第一行为。如此，可以在非LTM候选小区的测量结果上报的同时，对于LTM候选小区不执行第一行为，从而可以不对LTM候选小区进行第一测量，或者还可以不上报针对LTM候选小区第一测量的测量结果，可以避免频繁的乒乓切换，可提高LTM切换性能。
在一些可行的示例中，第一配置还可以包括第一信息或第二信息。第一信息和第二信息可以包含于同一指示中。例如，第一信息和第二信息中的一个包含于第一指示中，可以理解为第一指示用于指示第一信息或第二信息。示例性地，第一指示为1比特的指示信息，第一指示的取值可以为0或1，当第一指示的取值为0时表示第一指示用于指示第一信息，当第一指示的取值为1时表示第一指示用于指示第二信息；或当第一指示的取值为1时表示第一指示用于指示第一信息，当第一指示的取值为0时表示第一指示用于指示第二信息。第一指示或者可以为true或false，当第一指示的取值为true时表示第一指示用于指示第一信息，当第一指示的取值为flase时表示第一指示用于指示第二信息；或第一指示的取值为false时表示第一指示用于指示第一信息，当第一指示的取值为true时表示第一指示用于指示第二信息等。
第一信息和第二信息或者可以包含于不同的指示中。例如，第一信息为一个字段，第二信息为第二字段，如果网络设备配置了第一字段，则终端设备可以执行第一信息指示的行为，如果网络设备配置了第二字段，则终端设备可以执行第二信息指示的行为。
第一信息用于指示：如果第一小区不是LTM候选小区，针对第一小区执行第一行为；和/或如果第一小区是LTM候选小区，针对第一小区不执行第一行为。也就是说，第一信息用于指示终端设备对于不是LTM候选小区的第一小区执行第一行为，或者还用于指示终端设备对于是LTM候选小区的第一小区不执行第一行为。可以理解为第一信息用于指示终端设备执行步骤S703和/或步骤S803。
第二信息用于指示针对第一小区执行第一行为。也就是说，无论第一小区是否为LTM候选小区，都可针对第一小区执行第一行为。可以理解为第二信息用于指示终端设备不执行步骤S703和步骤S803，还可以理解为终端设备按照现有方法执行第一行为。通过执行第一信息，相对于执行现有技术中的第二信息而言，没有针对基于测量对象检测到的小区中的LTM候选小区执行第一行为，可以避免频繁的乒乓切换，提高了LTM切换性能。
在一些可行的示例中，第一配置还可以包括第二测量配置，图7和图8所示的通信方法还可以包括：终端设备根据第二测量配置执行第二测量。
其中，第二测量配置可以理解为针对第二测量的配置信息。本申请对于第二测量的类型和第二测量配置的内容不做限定，第二测量可以包括以下至少一项：层1测量、SSB测量、CSI-RS测量。第二测量配置可以包括以下一项或多项：测量周期、测量资源(例如，SSB或CSI-RS)、测量量配置、测量间隔、测量标识、S测量配置。
可以理解，在第一配置还包括第二测量配置的情况下，可以根据第二测量配置执行第二测量，还可以上报第二测量的测量结果，以使得网络设备基于第二测量的测量结果进行切换决策，在确认切换之后，终 端设备可以执行LTM切换过程，提高了切换效率。
在一些可行的示例中，终端设备针对第一小区执行第一行为可以包括：终端设备根据第一测量配置针对第一小区执行第一行为。
其中，第一测量配置还可以包括以下至少一项：测量标识、上报配置、测量量配置、测量间隔配置以及S配置等参数。可以理解，根据第一测量配置中的这些参数执行第一行为，可提高执行第一行为的准确率，利于提高切换性能。
第一测量的测量报告的上报需满足第一小区为LTM候选小区，还可以基于第一测量的上报配置进行上报。例如，在一些可行的示例中，针对第一小区执行第一行为可以包括：如果测量周期的定时器超时或测量事件满足测量上报触发条件，终端设备针对第一小区上报第一测量的测量结果。也就是说，可以在第一小区为非LTM候选小区的情况下，若测量周期的定时器超时，执行第一行为，即针对第一小区上报第一测量的测量结果。或者可以在第一小区为非LTM候选小区的情况下，若测量事件满足测量上报触发条件，执行第一行为，即针对第一小区上报第一测量的测量结果。如此，可以在测量周期的定时器超时或测量事件满足测量上报触发条件时，对于非LTM候选小区的第一测量的测量结果进行上报，网络设备可以基于这些上报的小区的测量结果触发层3切换，保证切换的性能。
结合上述的网络架构，请参阅图9，图9是本申请实施例提供的第三种通信方法的流程示意图。应理解，本申请中不同实施例的术语解释可以互相参考，为避免描述冗余，不同实施例可以不对同一术语赘述。如图9所示，该通信方法可以包括S901至步骤S904，其中：
步骤S901：网络设备向终端设备发送第三配置；其中，第三配置包括第一列表，第一列表包括至少一个小区。
相应地，终端设备接收来自网络设备的第三配置。
其中，第三配置和第一配置可以包含于相同的消息中，或者第三配置和第一配置可以包含于不同的消息中。第一列表中的小区不执行第一行为，第一行为包括第一测量和/或第一测量的测量结果的上报。第一列表中的小区包括LTM候选小区。此处的LTM候选小区可以为全部的LTM候选小区，或者可以包括部分的LTM候选小区。在一种示例中，第一列表中的小区包括部分候选小区。可以理解，上报部分的小区的第一测量的测量结果，可以节省功耗和空口资源。
应理解，第一列表可以与黑名单小区列表是两个单独的列表。黑名单中列表的小区用于禁止终端设备对该小区执行第一测量，黑名单列表中的小区可以包括LTM小区，还可以包括非LTM小区。而第一列表中的小区用于禁止执行第一行为，第一列表中包含部分或全部的LTM候选小区。对于被配置为第一列表中的小区，终端设备不会对该小区执行第一测量，终端设备可以执行第二测量，以用于LTM切换。
步骤S902：网络设备向终端设备发送第二配置；其中，第二配置包括第一测量配置，第一测量配置包括测量对象配置。
相应地，终端设备接收来自网络设备的第二配置。第二配置可以参照步骤S701的描述，在此不再赘述。
可选的，步骤S903：终端设备根据测量对象配置检测第一小区。
步骤S904：终端设备根据第一列表执行第一行为。
可选的，终端设备确定第一小区是否为第一列表中的小区。终端设备根据第一列表执行第一行为，通过如下实现方式中的一种实现：
方式1：如果第一小区不是第一列表中的小区，终端设备针对第一小区执行第一行为，且如果第一小区是第一列表中的小区，终端设备针对第一小区不执行第一行为；
方式2：如果第一小区不是第一列表中的小区，终端设备针对第一小区执行第一行为。可以理解为，终端设备仅对不属于第一列表的小区执行第一行为；
方式3：如果第一小区是第一列表中的小区，终端设备针对第一小区不执行第一行为。
在图9所示的通信方法中，终端设备接收来自网络设备的第二配置和第三配置，如果根据第二配置中测量对象配置检测到的第一小区是第三配置中第一列表中的小区，则终端设备可以针对该第一小区不执行第一行为。如果该第一小区不是第一列表中的小区，则可以针对该第一小区执行第一行为。如此，网络设备可以通过列表配置终端设备不执行第一行为的小区，通过网络配置的方式，提高了配置的灵活性。终端设备根据第一测量配置及网络配置的第一列表执行第一行为，针对部分LTM候选小区不执行第一行为，减少了终端设备的测量功耗，节省了测量上报的空口资源。此外，在一些网络部署中，网络设备需要进行 载波管理或LTM候选小区管理等功能，还可以配置不属于第一列表的LTM候选小区，以使终端设备对这些不属于第一列表的LTM候选小区执行第一测量，实现了小区管理或载波管理功能。
结合上述的网络架构，请参阅图10，图10是本申请实施例提供的第四种通信方法的流程示意图。应理解，本申请中不同实施例的术语解释可以互相参考，为避免描述冗余，不同实施例可以不对同一术语赘述。如图10所示，该通信方法可以包括S1001，其中：
步骤S1001：网络设备向终端设备发送第四配置；其中，第四配置包括第三信息，第三信息指示允许或禁止测量结果上报的测量事件类型。
相应地，终端设备接收来自网络设备的第四配置。
其中，第四配置和第一配置可以包含于相同的消息中，或者第四配置和第一配置可以包含于不同的消息中。第四配置可以包括第三信息，第三信息可用于指示允许测量结果上报的测量事件类型，或者用于指示禁止测量结果上报的测量事件类型。第三信息可以包括第二列表，该第二列表包括至少一种测量事件类型。若第二列表包括的测量事件类型为允许测量结果上报的测量事件类型，则第三信息用于指示允许测量结果上报的测量事件类型。若第二列表包括的测量事件类型为禁止测量结果上报的测量事件类型，则第三信息用于指示禁止测量结果上报的测量事件类型。
本申请对于允许或禁止测量结果上报的测量事件类型不做限定，可以为前述的测量事件的测量事件类型。例如，允许测量结果上报的测量事件类型为A1测量事件的测量事件类型，禁止测量结果上报的测量事件类型为A3测量事件的测量事件类型等。如此，在A1测量事件的测量结果满足A1测量事件的测量上报触发条件时，在A3测量事件的触发条件满足A3测量事件的测量上报触发条件时，不上报A3测量事件得到的测量结果。
在一些可行的示例中，还可以包括以下步骤：当第一小区的测量结果满足允许测量结果上报的测量事件类型的测量上报触发条件时，上报测量结果；和/或当第一小区的测量结果满足禁止测量结果上报的测量事件类型的测量上报触发条件时，不上报测量结果。
其中，第一小区为根据所述测量对象配置检测到的小区。
在一种理解中，第三信息可适用于任一小区。或者，在第二列表包括的测量事件类型为允许测量结果上报的测量事件类型的情况下，第三信息适用于第一小区；或在第二列表包括的测量事件类型为禁止测量结果上报的测量事件类型的情况下，第三信息不适用于第一小区。或者在另一种理解中，在第二列表包括的测量事件类型为允许测量结果上报的测量事件类型的情况下，第二列表中的测量事件适用于第一小区；或在第二列表包括的测量事件类型为禁止测量结果上报的测量事件类型，则第二列表中的测量事件不适用于第一小区。
在图10所示的通信方法中，终端设备接收来自网络设备的第四配置，根据第四配置中的第三信息确定允许或禁止测量结果上报的测量事件类型，从而终端设备可以基于每个事件类型上报或不上报该测量事件相关的结果，可以减少基于每个事件的测量结果的上报，节省了功耗和空口资源。例如，如果网络设备将A3事件包含在指示禁止测量结果上报的第二列表中，则UE基于第二列表不上报A3事件的测量结果，网络设备没有收到A3事件的测量结果，从而不会基于A3事件进行切换判决，这样就避免了层1和层3切换的冲突，避免了乒乓切换，可提高LTM切换性能。
在一些可行的示例中，还可以包括：网络设备向终端设备发送第二配置。其中，第二配置包括第一测量配置，第一测量配置包括测量对象配置。在一些可行的示例中，还可以包括：网络设备向终端设备发送第一配置。第一配置和第二配置可以参照图7和图8的实施例的描述，在此不再赘述。本申请对于第一配置、第二配置和第四配置的执行顺序不做限定。
在一些可行的示例中，还可以包括：如果根据测量对象配置检测到的第一小区是LTM候选小区，当第一小区的测量结果满足允许测量结果上报的测量事件类型的测量上报触发条件时，上报测量结果；和/或如果根据测量对象配置检测到的第一小区是LTM候选小区，针对第一小区不上报禁止测量结果上报的测量事件类型的测量事件的测量结果。
在一种理解中，在第二列表包括的测量事件类型为允许测量结果上报的测量事件类型的情况下，第三信息适用于第一小区中的LTM候选小区；在第二列表包括的测量事件类型为禁止测量结果上报的测量事件类型的情况下，第三信息不适用于第一小区中的LTM候选小区。或者在另一种理解中，在第二列表包括的测量事件类型为允许测量结果上报的测量事件类型的情况下，第二列表中的测量事件适用于第一小区中的LTM候选小区；或在第二列表包括的测量事件类型为禁止测量结果上报的测量事件类型的情况下， 第二列表中的测量事件不适用于第一小区中的LTM候选小区。
第一小区的测量结果满足允许测量结果上报的测量事件类型的测量上报触发条件，可以包括第一小区的测量结果中涉及的测量事件为允许测量结果上报的测量事件类型，且第一小区的测量结果满足测量事件的触发条件，例如，测量事件的持续时长超过预设的时间阈值等。
第一小区的测量结果满足允许测量结果上报的测量事件类型的测量上报触发条件，或者可以包括第一小区的测量结果中的测量参数满足预设的参数阈值。例如，第一小区的测量结果包括第一小区的信号质量，在一些可行的示例中，如果第一小区的信号质量小于信号质量阈值，确定第一小区的信号质量满足允许测量结果上报的测量事件类型的测量上报触发条件。也就是说，在第一小区的信号质量小于信号质量阈值时，表示信号质量较差，需要进一步判断是否切换，从而可以将第一小区的测量结果作为满足允许测量结果上报的测量事件类型的测量上报触发条件。通过上报第一小区的测量报告，可以提高切换判决的准确率，利于减小切换次数，提高切换性能。
可以理解，终端设备根据来自网络设备的第二配置中的测量对象配置检测第一小区，如果第一小区是LTM候选小区，第一小区的测量结果满足允许测量结果上报的测量事件类型的测量上报触发条件时，可以上报该测量结果。在第一小区是LTM候选小区，但第一小区的测量事件类型是禁止测量结果上报的测量事件类型时，即使第一小区的测量结果满足测量上报触发条件，也不上报该测量报告。如此，通过测量事件类型和测量上报触发条件筛选待上报的测量结果，可以避免不必要的测量上报，可节省功耗和空口资源，利于提高切换性能。可选的，针对第一小区中的非LTM候选小区的测量结果，可以上报。或者可以在非LTM候选小区的测量结果满足预设的测量上报触发条件时进行上报。
在一些可行的示例中，第一测量配置还可以包括第一测量周期，该通信方法还可以包括以下步骤：网络设备向终端设备发送第五配置；如果第一小区是LTM候选小区，基于第二测量周期针对第一小区执行第一测量；或如果第一小区不是LTM候选小区，基于第一测量周期针对第一小区执行第一测量。
其中，第二测量周期大于第一测量周期。第一测量周期适用于根据测量对象配置检测到的第一小区中的非LTM候选小区，第二测量周期适用于第一小区中的LTM候选小区。也就是说，在第一小区是非LTM候选小区时，可以基于第一测量周期针对第一小区执行第一测量。而在第一小区是LTM候选小区时，可以基于第二测量周期针对第一小区执行第一测量。如此，LTM候选小区的测量周期(或测量窗)可以大于非LTM候选小区的测量周期，以减小针对LTM候选小区的第一测量，从而减少测量结果的上报，可以节省功耗和空口资源，利于提高LTM切换性能。
采用第五配置进行切换控制的方法，可请参阅图11，图11是本申请实施例提供的第五种通信方法的流程示意图。应理解，本申请中不同实施例的术语解释可以互相参考，为避免描述冗余，不同实施例可以不对同一术语赘述。如图11所示，该通信方法可以包括步骤S1101至步骤S1106，其中：
步骤S1101：网络设备向终端设备发送第二配置；其中，第二配置包括第一测量配置，第一测量配置包括测量对象配置和第一测量周期。
相应地，终端设备接收来自网络设备的第二配置。
步骤S1102：网络设备向终端设备发送第五配置；其中，第五配置包括第二测量周期，第二测量周期大于第一测量周期。
相应地，终端设备接收来自网络设备的第五配置。
可选的，步骤S1103：终端设备根据测量对象配置检测第一小区。
可选的，步骤S1104：终端设备确定第一小区是否为LTM候选小区。
如果第一小区是LTM候选小区，则执行步骤S1105：终端设备基于第二测量周期针对第一小区执行第一测量。如果第一小区不是LTM候选小区，则执行步骤S1106：终端设备基于第一测量周期针对第一小区执行第一测量。
其中，步骤S1103和步骤S1104可以在LTM候选小区的数量为1时，根据第一小区是否为LTM候选小区执行其中的一个。若存在是LTM候选小区的第一小区，且存在不是LTM候选小区的第一小区，则步骤S1103和步骤S1104都执行。
在图11所示的通信方法中，终端设备接收来自网络设备发送的第二配置和第五配置，可以根据第二配置中的测量对象配置确定第一小区，在第一小区是非LTM候选小区时，基于第一测量周期针对第一小区执行第一测量。或者还可以在第一小区是LTM候选小区时，可以基于第二测量周期针对第一小区执行第一测量。如此，LTM候选小区的测量周期(或测量窗)可以大于非LTM候选小区的测量周期，以减小 LTM候选小区的测量结果的上报，可以节省功耗和空口资源，利于提高LTM切换性能。
