技术领域
本申请涉及通信领域，具体地，涉及一种通信方法和装置。
背景技术
在无线网络中，一个终端可能和多个基站通信，即进行双连接(dual connectivity，DC)通信。在DC中，终端可以与主基站和辅基站进行通信，并且UE接入的辅基站也可能发生切换，即，由源辅基站切换到目标辅基站。UE可以将源辅基站切换到目标辅基站过程中的信息记录在辅小区成功切换报告(successfulPSCell change report，SPCR)中，并上报给网络节点。
即使终端成功切换到了目标辅基站，在切换过程中可能存在导致将来发生辅基站切换失败的潜在问题，如果网络节点识别出此类潜在问题，可以据此对终端进行移动性优化。因此，SPCR中可以包含与这些潜在问题相关的信息，这些信息可以称为潜在失败信息。
由于主基站、源辅基站和目标辅基站都能够给终端配置记录SPCR的触发条件。例如，主基站和源辅基站均向终端配置了记录SPCR的触发条件，因此，终端可能会将SPCR发送到错误的网络节点，导致无法准确地对终端进行移动性优化。

图1示出了本申请适用的双连接通信系统。该系统中包括UE、主基站、源辅基站和目标辅基站。
该双连接通信系统可以为新无线双连接(new radio dual connectivity，NR-DC)系统，该系统中主基站为连接5G核心网的NR基站，辅基站为NR基站。
或者，该双连接通信系统可以为下一代(next generation，NG)无线接入网络(radio access network，RAN)演进的通用陆基无线接入(evolved universal terrestrial radio access，E-UTRA)及NR的双连接(NG-RAN E-UTRA-NR dual connectivity，NGEN-DC)系统，该系统中主基站为连接5G核心网的LTE基站，辅基站为NR基站。
或者，该双连接通信系统可以为E-UTRA及NR的双连接(E-UTRA-NRdual connectivity，EN-DC)系统，该系统中主基站为连接4G核心网的LTE基站，辅基站为NR基站。
或者，该双连接通信系统可以为NR及E-UTRA的双连接(NR-E-UTRA dual connectivity，NE-DC)系统，该系统中主基站为连接5G核心网的NR基站，辅基站为LTE基站。
以上这些双连接通信系统可以统称为多空口双连接(multi-radio dual connectivity，MR-DC)通信系统。
在双连接通信系统中，与主基站关联的一组服务小区可称为主小区组(master cell group，MCG)。主小区组中包括主小区(primary cell，PCell)。主基站也可以称为主节点(master node，MN)。与辅基站关联的(associated)一组服务小区可被称为辅小区组(secondary cell group，SCG)，辅小区组中的主小区可以称为主辅小区(primary SCG cell，PSCell)。辅基站也可以称为辅节点(secondary node，SN)。主基站与核心网之间可以建立控制面连接，主基站与辅基站可以分别与核心网可以建立数据面连接。
在终端切换辅基站的场景中，源辅基站管理的主辅小区称为S-PSCell(source PSCell)，目标辅基站管理的主辅小区称为T-PSCell(target PSCell)。
本申请中，终端可以是向用户提供语音和/或数据连通性的各类设备，也可以称为终端设备、用户设备(user equipment，UE)、移动台、移动终端等。终端可以广泛应用于各种场景，例如，设备到设备(device-to-device，D2D)、车物(vehicle to everything，V2X)通信、机器类通信(machine-type communication，MTC)、物联网(internet of things，IOT)、虚拟现实、增强现实、工业控制、自动驾驶、远程医疗、智能电网、智能家具、智能办公、智能穿戴、智能交通、智慧城市等。终端可以是手机、平板电脑、带无线收发功能的电脑、可穿戴设备、航空航天设备等。在本申请实施例中，应用于上述设备中的芯片也可以称为终端。本申请中以UE作为终端进行说明。
本申请实施例中的网络节点可以是基站等接入网设备，该基站可以是全球移动通讯(global system ofmobile communication，GSM)系统或码分多址(code division multiple access，CDMA)中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)系统中的基站，还可以是LTE系统中的演进型基站(evolutional nodeB，eNB或eNodeB)，第五代(5th generation，5G)移动通信系统中的下一代基站(next generation NodeB，gNB)、第六代(6th generation，6G)移动通信系统中的下一代基站、未来移动通信系统中的基站等。本申请的实施例对网络节点所采用的具体技术和具体设备形态不做限定。例如，网络节点也可以是完成基站部分功能的模块或单元，例如，可以是集中式单元(central unit，CU)，也可以是分布式单元(distributed unit，DU)。其中，CU和DU分别完成基站的一部分协议栈功能。此外，CU的功能可以由多个实体实现例如，将CU的控制面(control plane，CP)和用户面(user plane，UP)的功能分离，形成CU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，并通过E1接口相连，CU-CP和CU-UP可以与DU相耦合。
UE从源辅基站切换到目标辅基站的过程中可能出现潜在失败的情况。本申请中，潜在失败可以是指：UE成功从源辅基站切换到了目标辅基站，但是在切换过程中存在一些可能导致未来出现切换过程失败的问题，比如，存在UE从源辅基站切换到目标辅基站的时间超过预设时长的问题。出现潜在失败的情况下，UE可以被触发记录SPCR，SPCR中可以包含与前述潜在失败相关的信息，这些信息可以称为潜在失败信息。
导致以上潜在失败可以是：UE与主基站之间的通信链路出现潜在失败，或者UE与源辅基站之间的通信链路出现潜在失败，或者，UE与目标辅基站之间的通信链路出现潜在失败。以上任意一条通信链路出现潜在失败的原因可以是：该通信链路的信号质量低于预设阈值。可以理解，如果以上一条或多条通信链路信号质量较差，UE可能需要等待信号质量转好，或者需要尝试更多次才能接入到目标辅基站，因此，UE从源辅基站切换到目标辅基站的时间可能会超过预设时长。
UE从源辅基站切换到目标辅基站的时间是否超过预设时长可以由预设的定时器运行时长是否超时来体现。
为了方便理解，下面对本申请涉及的几个定时器进行说明。
定时器T304(以下简称T304)：
T304的运行时长指示UE接收辅基站切换命令之后未接入目标辅基站的时长。如果T304的运行时长大于或等于阈值1时，UE确定发生切换失败，即UE确定接入目标辅基站失败；如果T304的运行时长大于或等于阈值2时，UE确定存在发生切换失败的可能性， 触发记录SPCR。这里阈值1大于阈值2。
定时器T310(以下简称T310)：
T310的运行时长指示UE检测到与基站(例如，源辅基站或主基站)之间存在物理层问题(physical layer problems)(该问题通常是连续收到的下行失步指示超过一定阈值)的时长。启动T310之后，该T310运行期间，如果无线链路恢复，则该定时器T310停止。如果T310的运行时长大于或等于阈值3，UE确定UE与基站(例如，源辅基站或主基站)之间发生无线链路失败；如果T310的运行时长大于或等于阈值4，UE确定UE与基站(例如，源辅基站或主基站)之间存在发生无线链路失败的可能性，触发记录SPCR。这里阈值3大于阈值4。
定时器T312(以下简称T312)：
T312在T310的运行期间启动。T312的运行时长指示UE与基站(例如，源辅基站或主基站)之间恢复同步的时长。如果T312的运行时长大于或等于阈值5，UE确定UE与基站(例如，源辅基站或主基站)之间发生无线链路失败；如果T312的运行时长大于或等于阈值6时，UE确定UE与基站(例如，源辅基站或主基站)之间存在发生无线链路失败的可能性，触发记录SPCR。这里阈值5大于阈值6。
在辅基站切换过程中，主基站、源辅基站和目标辅基站都可能给UE配置记录SPCR的触发条件。例如，主基站和源辅基站均向UE配置了T312的超时门限，如果T312超时，则UE记录SPCR。但是，由于T312的超时门限可以是主基站配置的，也可以是源辅基站配置的，因此，UE不能确定需要将该SPCR发送到主基站还是源辅基站，因此，UE可能会将记录的SPCR发送到错误的基站。
为了解决上述问题，图2示出了本申请提供的方法200，在该方法中，UE记录的SPCR与触发记录该SPCR的节点存在对应关系，从而UE可以将该SPCR发送到正确的节点。
具体地，该方法200包括：
S201，第一节点发送第一信息。相应地，UE接收来自第一节点的第一信息。
第一信息指示记录第一报告的触发条件。示例性地，该第一报告可以为SPCR，或者第一报告的名称也可以为其他名称，本申请对此不作限定。下文以第一报告为SPCR进行说明。
情况1：
该第一节点为UE接入的源主基站(以下称为主基站#1)。第一节点可以直接向UE发送第一信息(记为第一信息#1)。例如，主基站#1可以向UE发送辅基站切换命令，该辅基站切换命令中包括第一信息#1。UE可以根据辅基站切换命令执行辅基站切换流程。
示例性地，主基站#1确定对UE进行RRC重配置，从而向UE发送辅基站切换命令。例如，当源辅基站的负载过大时，主基站#1确定对UE进行RRC重配置。
记录SPCR的触发条件#1可以为UE与主基站#1之间的通信链路出现潜在失败。例如，触发条件#1可以为T312超时或T310超时。应理解，第一信息#1中包括T312的超时门限和/或T310的超时门限。关于T312和T310的相关介绍可以参考上文。
应理解，这里的“源主基站”仅是为了与下文中的“目标主基站”进行区分，并不意味着UE接入的主基站一定会切换，或者，即使UE进行了主基站切换流程，源主基站和目标主基站也可能是同一个基站。
情况2：
该第一节点为目标辅基站。第一节点可以通过UE接入的主基站#1向UE发送第一信息(记为第一信息#2)。例如，目标辅基站向主基站#1发送无线资源控制(radio resource control，RRC)重配置消息，第一信息#2以容器(container)的方式包含于该RRC重配消息中。主基站#1再向UE发送辅基站切换命令，第一信息#2以容器的方式包含于该辅基站切换命令中。
记录SPCR的触发条件#2可以为UE与目标辅基站之间的通信链路出现潜在失败。例如，触发条件#2可以为T304超时。应理解，第一信息#2中包括T304的超时门限。关于T304的相关介绍可以参考上文。
情况3：
该第一节点为UE接入的源辅基站。第一节点可以通过UE接入的主基站#1向UE发送第一信息(记为第一消息#3)。例如，源辅基站向主基站#1发送RRC重配置消息，第一信息#3以容器(container)的方式包含于该RRC重配消息中。主基站#1再向UE发送辅基站切换命令，第一信息#3以容器的方式包含于该辅基站切换命令中。
记录SPCR的触发条件#3可以为UE与源辅基站之间的通信链路出现潜在失败。例如，触发条件#3可以为T312超时或T310超时。应理解，第一信息#3中包括T312的超时门限和/或T310的超时门限。
应理解，触发条件#1中的T312超时门限和触发条件#3中的T312超时门限可以不同，也可以相同。换句话说，主基站#1配置的T312超时门限和源辅基站配置的T312超时门限可以不同，也可以相同。
类似地，触发条件#1中的T310超时门限和触发条件#3中的T310超时门限可以不同，也可以相同。
应理解，上述三种情况可以发生其中的一项或多项。例如，主基站#1向UE发送辅基站切换命令，该辅基站切换命令中包括第一信息#1、第一信息#2和第一信息#3中的一项或多项，从而UE可以获取触发条件#1至触发条件#3中的一项或多项。
可选地，步骤S201是UE在执行辅基站切换之前进行的。UE可以先获取来自第一节点的第一信息，后续主基站#1可以向UE发送辅基站切换命令，UE根据该辅基站切换命令执行辅基站切换流程。
S202，在满足触发条件的情况下，UE记录SPCR，该SPCR与第一节点之间存在对应关系。
该SPCR中包括UE在辅基站切换过程中的信息，示例性地包括以下中的一项或多项：
源辅基站管理的S-PSCell的小区标识(cell ID)、目标辅基站管理的T-PSCell的cell ID、在目标辅基站的随机接入信息、邻区的信道测量量、超时的定时器类型、UE与源辅基站最后一次数据传输到UE与目标辅基站第一次数据传输之间的时间间隔。应理解，该邻区可以为源辅基站管理的S-PSCell的邻区和/或目标辅基站管理的T-PSCell的邻区。
以上这些信息可以是与UE切换到所述目标辅基站过程中存在的潜在失败相关的，也可以称为潜在失败信息。
作为一种方式，SPCR中可以包括第一节点的标识信息。UE将第一节点的标识信息记录在SPCR中。
作为另一种方式，第一节点的标识信息是独立于SPCR的信息。
可选地，UE发送包含第一节点的标识信息与SPCR的一条消息。可选地，第一节点的标识信息与SPCR也可以包含在不同消息中。可以将SPCR作为一个容器(container)，SPCR中可以不包括第一节点的标识信息，UE将第一节点的标识信息作为一个独立的信元记录到SPCR之外。应理解，如果将第一节点的标识信息记录到SPCR之外，一方面下文中的至少一个中间节点可以不解析SPCR就获取第一节点的标识信息，从而降低SPCR的发送时延，另一方面也可以避免因基站制式不同而导致下文中的至少一个中间节点无法解析SPCR的情况。
总之，通过上述两种方式，UE不仅仅记录了SPCR，还记录该SPCR对应的第一节点的标识信息，使得SPCR能够关联到第一节点。由于该SPCR是由第一节点发送的触发条件被触发记录的，该SPCR可以包含与第一节点相关的潜在失败信息，因此，第一节点可以被认为是该SPCR对应的目的节点，也就是说，最终该SPCR可以被发送到第一节点，第一节点根据该SPCR进行移动性参数优化，解决潜在失败问题。
该第一节点的标识信息用于表征该SPCR对应的触发条件的来源。该来源可以为上述主基站#1、源辅基站或目标辅基站。
例如，第一节点的标识信息可以为小区全球标识(cell global identity，CGI)或封闭接入组(closed access group，CAG)标识。
SPCR的格式与作为目的节点的第一节点的制式是对应的，从而，目的节点可以解析SPCR。可以理解，如果接收到SPCR的网络节点的制式与该SPCR的格式不对应，则该网络节点不能解析该SPCR。其中，SPCR的格式可以是指承载第一报告的无线资源控制(raido resource control，RRC)层信令的格式，例如，不同格式的RRC层信令中的信元设计可以不同。示例性地，如果第一节点为LTE基站，则该SPCR为LTE格式的；如果第一节点为NR基站，则该SPCR为NR格式的。
S203，UE向第一节点发送SPCR。相应地，第一节点接收来自UE的SPCR。
例如，第一节点为主基站#1，则UE向主基站#1发送SPCR#1。
又例如，第一节点为目标辅基站，则UE向目标辅基站发送SPCR#2。
又例如，第一节点为源辅基站，则UE向源辅基站发送SPCR#3。
后续将对传输SPCR的过程进行详细说明。
S204，第一节点根据SPCR对辅基站切换流程进行优化。
示例性地，SPCR中包括邻区信道测量量，第一节点可以根据该邻区信道测量量选择信道质量较好的小区用于后续其他UE进行辅基站切换。例如，根据SPCR报告，主基站#1确定UE在目标辅基站的接入时间过长，而邻站的信道测量结果又好于目标辅基站的信道测量结果，则针对之后切换辅基站的UE，主基站#1可以将这些UE优先向信道测量结果更好的邻站切换。
又例如，根据SPCR报告，主基站#1或源辅基站确定由于切换时间过晚，导致UE成功接入到目标辅基站之前，UE和源辅基站之间已经出现多次下行失步，则主基站#1或源辅基站可以将其他UE执行辅基站切换的时间提前。
又例如，根据SPCR报告，目标辅基站确定由于切换时间过早导致潜在失败，目标辅基站可以向主基站#1发送指示信息，以将其他UE执行辅基站切换的时间推迟。
根据本申请的方法，UE能够正确及时地将SPCR发送到第一节点，使得该SPCR能有效用于进行移动性参数优化，从而提高SPCR的利用效率，提升移动性优化效果。此外，基于第一节点优化的移动性参数，可以提高后续辅基站切换流程的成功率，保障双连接通信的连续性。
下面对S203中UE向第一节点发送SPCR的方式进行详细说明：
方式1：
UE直接向第一节点发送SPCR。
情况1：
如果满足触发条件#1，UE记录SPCR#1和主基站#1的标识信息(例如，主基站#1管理的PCell的CGI)。
即，SPCR#1与主基站#1对应，SPCR#1最终应发送到主基站#1。
应理解，在情况1中，UE可以将主基站#1的标识信息记录到SPCR#1中，或者作为独立的信息记录到SPCR#1之外，不予限制。
UE根据记录的主基站#1的标识信息向主基站#1发送SPCR#1。
情况2：
如果满足触发条件#2，UE记录SPCR#2和目标辅基站的标识信息(例如，目标辅基站管理的T-PSCell的CGI)。
应理解，在情况2中，UE可以将目标辅基站的标识信息记录到SPCR#2中，或者作为独立的信息记录到SPCR#2之外，不予限制。
UE根据记录的目标辅基站的标识信息向目标辅基站发送SPCR#2。
方式2：
如图3所示，UE通过至少一个中间节点向第一节点发送SPCR。该至少一个中间节点中包括第一中间节点，可选地还包括第二中间节点。
此时，UE还向第一中间节点发送第一节点的标识信息。应理解，如果该至少一个中间节点包括第二中间节点，则UE还向第一中间节点发送第二中间节点的标识信息。
该第一中间节点为UE接入的节点。
在一个实施方式中，UE根据第一中间节点与第一节点的制式，判断第一中间节点是否支持该SPCR对应的RAT。换言之，UE判断第一中间节点是否能够解析SPCR。具体地，如果第一中间节点与第一节点为相同制式的基站，则第一中间节点支持该SPCR对应的RAT，即，第一中间节点能够解析该SPCR。如果第一中间节点与第一节点为不同制式的基站，则第一中间节点不支持该SPCR对应的RAT，即，第一中间节点不能解析该SPCR。
例如，如果第一中间节点与第一节点均为LTE基站，或者均为NR基站，则第一中间节点与第一节点为相同制式的基站；如果其中一个为LTE基站，另一个为NR基站，则第一中间节点与第一节点为不同制式的基站；如果其中一个为NR基站，另一个为未来6G系统中的基站，则第一中间节点与第一节点为不同制式的基站。
如果UE确定第一中间节点能够解析SPCR，则SPCR中包括第一节点的标识信息。即，S204中UE在记录该SPCR时，将第一节点的标识信息也记录到SPCR中；或者，UE也可以将第一节点的标识信息作为独立于SPCR的信息记录。
如果UE确定第一中间节点不能够解析SPCR，则UE可以将第一节点的标识信息作 为独立于SPCR的信息记录，即，将第一节点的标识信息记录到SPCR之外。例如，SPCR作为一个container，且将第一节点的标识信息作为该container之外的信元。进而，UE可以发送包含该container以及第一节点的标识信息的消息给第一中间节点。
该第一中间节点可以为前述主基站#1、目标辅基站或主基站#2(目标主基站的一例)。该主基站#2为UE发生主基站切换后接入的主基站(即，从主基站#1切换到主基站#2)。
下面结合不同的场景对方式2进行描述。
##场景1：NR-DC场景，主基站#1为连接5G核心网的NR基站，源辅基站和目标辅基站为NR基站。
a：第一中间节点为主基站#1。
如果满足触发条件#3，UE以NR格式记录SPCR#3。由于源辅基站与主基站#1制式相同，UE确定主基站#1能够解析该SPCR#3，则在S202中UE可以将源辅基站的标识信息记录到SPCR#3中。当然，UE也可以把源辅基站的标识信息记录在SPCR#3之外。
例如，源辅基站的标识信息可以为源辅基站管理的S-PSCell的CGI。
以SPCR#3中包括源辅基站的标识信息为例，具体的发送过程包括：
步骤1：UE向主基站#1发送SPCR#3。
步骤2：主基站#1根据SPCR#3中包括的源辅基站的标识信息，向源辅基站发送SPCR#3。
具体地，UE和主基站#1可以通过一个消息或多个消息发送SPCR#3，本申请对此不作限定。
b：第一中间节点为主基站#2，且主基站#2为NR基站。
此时，由于主基站#2与第一节点的制式相同，UE确定主基站#2能够解析SPCR，UE可以将第一节点的标识信息记录在SPCR中。当然，UE也可以把第一节点的标识信息记录在SPCR之外。下面以将第一节点的标识信息记录在SPCR中为例进行说明。
示例一：如果满足触发条件#1，UE记录SPCR#1。SPCR#1中可以包括主基站#1的标识信息。

作为第一种情况，SPCR#2中可以包括目标辅基站的标识信息、主基站#1的标识信息和指示信息，该指示信息用于指示主基站#1为传输SPCR#2的中间节点，目标辅基站为SPCR#2对应的目的节点。即，可以通过直接(显式)指示的方式通知主基站#2，中间节点和目的节点分别是哪一个节点。
或者，该指示信息用于指示主基站#1为传输SPCR#2的中间节点。此时，可以在UE和主基站#2中提前配置规则，默认目标辅基站为SPCR#2对应的目的节点。
或者，该指示信息用于指示目标辅基站为SPCR#2对应的目的节点。此时，可以在UE和主基站#2中提前配置规则，默认主基站#1为传输SPCR#2的中间节点。
作为第二种情况，UE不向主基站#2发送上述指示信息。在UE和主基站#2中预先配置确定中间节点和目的节点的规则，通过间接(隐式)指示的方式通知主基站#2，中间节点和目的节点分别为哪一个节点。
例如，按目标辅基站的标识信息和主基站#1的标识信息在一组比特中的顺序确定中间节点和目的节点。例如，一组比特中前5个比特用于指示传输SPCR#2的中间节点，后5个比特用于指示SPCR#2对应的目的节点。
又例如，可以预先在UE和主基站#2中配置，SPCR中包括的基站标识为目的节点的标识，SPCR之外的基站标识为中间节点的标识。即，主基站#1的标识信息在SPCR#2之外，目标辅基站的标识信息在SPCR#2之内。
