目前，为了降低配置条件主辅小区添加/变更(conditional PSCell addition/change，CPAC)占用的开销，终端设备可以基于一个CPAC配置进行多轮CPAC，又称“连续CPAC过程”。这样，网络设备无需在每轮CPAC的过程中为终端设备重新提供CPAC配置。然而，传统的CPAC配置中仅会包含一个SCG的SCG状态，在连续CPAC过程中，终端设备经过多轮CPAC过程需要变更到多个SCG，此时，终端设备无法获知多个SCG中每个SCG的SCG状态，导致终端设备、主节点、辅节点的理解不一致，从而终端设备与主节点、辅节点之间无法正常通信。

为了便于理解，下文结合图1介绍条件主辅小区添加/变更(conditional PSCell addition/change，CPAC)过程。
图1中，终端设备103或终端设备104可以与网络设备101和网络设备102双连接，其中，一个网络设备为MN，另一个网络设备为SN。MN中的一个或多个服务小区属于主小区组(master cell group，MCG)。通常，MCG可以包括主小区(primary cell，PCell)。在一些实现方式中，MCG除了包含PCell，还可以包括一个或多个辅小区(secondary cell，SCell)。SN中的一个或多个服务小区属于辅小区组(secondary cell group，SCG)。通常，SCG中可以包括主辅小区(primary secondary cell，PSCell)。在一些实现方式中，SCG除了包括PSCell还可以包括一个或多个SCell。
在图1所示的通信系统10中，终端设备103或终端设备104可以进行CPAC。例如， 终端设备103可以通过下述示例1进行条件主辅小区添加(conditional PSCell addition，CPA)，通过下述示例2进行条件主辅小区变更(conditional PSCell change，CPC)。
示例1，以终端设备103与网络设备101建立了RRC连接，终端设备103要进行CPA，与网络设备102建立连接为例，网络设备101与终端设备103建立RRC连接后，可以为终端设备103配置一个或多个候选PSCell，该一个或多个候选PSCell包括网络设备102为终端设备103配置的PSCell和其他网络设备为终端设备103配置的PSCell；网络设备101向终端设备103发送该一个或多个候选PSCell的配置信息1，候选PSCell的配置信息1包括候选PSCell的配置1和添加条件。终端设备103接收到来自网络设备101的该一个或多个候选PSCell的配置信息1，可以检测该一个或多个候选PSCell的添加条件，在检测到至少一个满足添加条件的候选PSCell时，终端设备103选择其中一个候选PSCell(如网络设备102为终端配置的候选PSCell)，并应用该候选PSCell的配置。后续，终端设备103与该候选PSCell发起随机接入，并在候选PSCell随机接入成功之后，与网络设备101和网络设备102建立了双连接。其中，候选PSCell的配置信息1也可以称为候选PSCell的CPA配置信息1，本申请实施例对该配置信息的名称不予限制。
可以理解的，终端设备103检测到多个满足添加条件的候选PSCell时，可以根据预置的策略选择一个候选PSCell，并应用该候选PSCell的配置。例如，终端设备103检测到多个满足添加条件的候选PSCell时，可以随机选择一个候选PSCell，并应用该候选PSCell的配置；或者，可以在该多个满足添加条件的候选PSCell中，选择信号质量最好的候选PSCell，并应用该候选PSCell的配置；或者，可以在该多个满足添加条件并且波束(beam)数量大于或等于门限值的候选PSCell中，选择波束数量最多的候选PSCell，并应用该候选PSCell的配置。上述仅是终端设备103选择候选PSCell的示例，终端设备103还可以通过其他方式选择候选PSCell，不予限制。
示例2，以终端设备103与网络设备101和网络设备102双连接，网络设备101为MN，网络设备102为SN，终端设备103要进行CPC为例，网络设备101可以为终端设备103配置一个或多个候选PSCell；网络设备101向终端设备103发送该一个或多个候选PSCell的配置信息2，候选PSCell的配置信息2包括候选PSCell的配置2和变更条件。终端设备103接收到来自网络设备101的该一个或多个候选PSCell的配置信息2，可以检测该一个或多个候选PSCell的变更条件，在检测到至少一个满足变更条件的候选PSCell时，终端设备103选择其中一个候选PSCell，并应用该候选PSCell的配置。后续，终端设备103与该候选PSCell发起随机接入，并在候选PSCell随机接入成功之后，与网络设备101和该候选PSCell所属辅基站建立了双连接。其中，候选PSCell的配置信息2也可以称为候选PSCell的CPC配置信息2，不予限制。
可以理解的，终端设备103检测到多个满足变更条件的候选PSCell时，可以根据预置的策略选择一个候选PSCell，并应用该候选PSCell的配置。例如，终端设备103检测到多个满足变更条件的候选PSCell时，可以随机选择一个候选PSCell，并应用该候选PSCell的配置；或者，可以在该多个满足变更条件的候选PSCell中，选择信号质量最好的候选PSCell，并应用该候选PSCell的配置；或者，可以在该多个满足变更条件并且波束(beam)数量大于或等于门限值的候选PSCell中，选择波束数量最多的候选PSCell，并应用该候选PSCell的配置。上述仅是终端设备103选择候选PSCell的示例，终端设备103还可以通过其他方式选择候选PSCell，不予限制。
需要说明的是，在本申请实施例中，对于任一网络设备为终端配置的一个或多个候选PSCell中的任一候选PSCell，终端进行CPA时，候选PSCell的配置信息1，以及终端进行CPC时，候选PSCell的配置信息2可以统称为候选PSCell的配置信息，终端进行CPA时候选PSCell的配置1以及终端进行CPC时候选PSCell的配置2可以统称为候选PSCell的配置。该候选PSCell的配置信息包括候选PSCell的配置和添加/变更条件。其中，终端 进行CPA时，候选PSCell的配置用于终端添加该候选PSCell后，与该候选PSCell通信，候选PSCell的添加/变更条件包括候选PSCell的添加条件，候选PSCell的添加条件用于终端确定是否添加该候选PSCell。终端进行CPC时，候选PSCell的配置用于终端将源PSCell变更为该候选PSCell后与该候选PSCell通信，候选PSCell的添加/变更条件包括候选PSCell的变更条件，候选PSCell的变更条件用于终端确定是否将源PSCell变更为该候选PSCell。
在终端设备103接收到了一个或多个候选PSCell的配置和添加/变更条件，但是还没有检测出满足添加/变更条件的PSCell时，终端设备103还可以从当前MN切换到信号质量较好的目标MN，例如，终端设备103可以从网络设备101切换到网络设备105上。通常，当终端设备103执行MN切换后，当前MN会释放为终端设备103配置的一个或多个候选PSCell，目标MN与终端设备103建立RRC连接后，可以重新为终端设备103配置一个或多个候选PSCell，并向终端设备103发送目标MN为终端配置的一个或多个候选PSCell的配置信息用于终端进行CPAC，目标MN为终端配置的一个或多个候选PSCell的配置信息包括该候选PSCell的配置和添加/变更条件。
通常，候选PSCell的配置和添加/变更条件一般包括较多的信息，例如，候选PSCell的配置包括：候选PSCell的配置的标识，和/或，候选PSCell为终端分配的随机接入资源，和/或，小区无线网络临时标识(cell radio network temporary identifier，CRNIT)，和/或，候选PSCell的全球小区识别码(cell global identification，CGI)，和/或，候选PSCell的物理小区标识(physical cell identifier，PCI)，和/或，候选PSCell对应的频率信息。候选PSCell对应的频率信息可以包括以下一种或多种：同步信号块的绝对频率(如absoluteFrequency SSB)、参考资源模块(common RB0)的绝对频率位置(如absoluteFrequencyPointA)、频率带宽列表(如frequencyBandList)、子载波间隔(subcarrier spacing，SCS)特定的载波列表(如scs-SpecificCarrierList)等。候选PSCell的配置还包括候选PSCell对应的资源信息，候选PSCell对应的资源信息包括以下一种或多种：承载配置参数(radioBearerConfig)、小区组配置(cellGroupConfig)参数、物理层(physical layer，PHY layer)配置参数、媒体接入控制(media access control，MAC)层配置参数、无线链路控制(radio link control，RLC)层配置参数、分组数据汇聚层协议(packet data convergence protocol，PDCP)层配置参数、服务数据适配协议(service data adaptation protocol，SDAP)层配置参数或RRC层配置参数。候选PSCell的配置也可以称为候选PSCell的CPAC配置、候选PSCell的CPAC配置信息等，本申请实施例对上述配置的名称不作具体限定。
候选PSCell的添加/变更条件用于终端确定是否添加该候选PSCell，或者用于终端确定是否将源PSCell变更为该候选PSCell，例如，若终端检测到候选PSCell满足该候选PSCell的添加/变更条件时，终端确定添加该候选PSCell，或者将源PSCell变更为该候选PSCell，若终端检测到候选PSCell不满足该候选PSCell的添加/变更条件时，终端确定不添加该候选PSCell，或者不将源PSCell变更为该候选PSCell。
可选的，候选PSCell的添加/变更条件包括候选PSCell的添加/变更条件的执行事件类型，该执行事件类型也可以称为测量事件或者上报事件等。终端可以测量该候选PSCell的信号质量，或者测量该候选PSCell的信号质量和该候选PSCell的邻区的信号质量，并根据测量结果和该执行事件类型确定是否添加该候选PSCell，或者确定是否将源PSCell变更为该候选PSCell。
一种可能的实现方式，该执行事件类型包括一个或多个事件，例如，该执行事件类型可以包括以下事件中的一种或多种：事件A3、事件A4、事件A5、事件B1、或事件B2。其中，事件A3表示邻区信号质量比特殊小区(special cell，SpCell)信号质量大于或等于一定的偏置(offset)。事件A4表示邻区信号质量大于或等于一定门限。事件A5表示SpCell信号质量小于或等于门限1(threshold 1)，并且邻区信号质量大于或等于门限2(threshold 2)。事件B1表示跨无线接入技术(inter radio access technology，inter RAT)的邻区信号质量大于 或等于一定的门限。事件B2表示PCell信号质量小于或等于门限3(threshold 3)，并且inter RAT的邻区信号质量大于或等于门限4(threshold 4)。上述事件仅是执行事件类型中事件的示例，执行事件类型还可以包括其他事件，不予限制。该执行事件类型还包括该执行事件类型中事件对应的门限值。该执行事件类型还包括满足该执行事件类型中事件的时间长度(time To Trigger)，和/或，进入/离开该执行事件类型中事件时的迟滞值(hysteresis)等。另外，该执行事件类型中的事件可以对应一个或多个门限值，例如，事件A5对应两个门限值。该执行事件类型中的同一个事件可以对应不同的测量量，例如，事件A3可以对应A3参考信号接收功率(reference signal received power，RSRP)和A3参考信号接收质量(reference signal received quality，RSRQ)。
通常，在终端设备执行上文介绍的CPAC过程之前，网络设备会为终端设备提供CPAC配置，相应地，终端设备在基于网络设备提供的CPAC配置变更PSCell。在一些实现方式中，网络设备可以根据业务情况(例如，传输时延、待传输数据的数据量等)以及信道测量情况(例如，信道状态)来判断终端设备是否需要CPAC。
另外，在一些实现方式中，上述CPAC配置可以包括候选小区配置列表、执行条件以及小区配置。
上述候选小区列表可以理解为是用于CPA或CPC的候选小区配置列表。在该候选小区列表中可以包含一个或多个候选小区的小区信息。每个候选小区的小区信息可以包含配置信息标识。需要说明的是，配置信息的ID可以基于网络设备为终端设备配置的候选小区的数量确定。例如，网络设备为终端设备提供5个候选小区的配置信息，那么上述小区的配置信息ID可以用于标识5个候选小区的配置信息。
上述执行条件可以是用于指示终端设备执行CPA或CPC的执行条件。
上述小区配置可以由候选SN提供给MN的SCG配置。在一些实现方式中，上述SCG配置可以由SN通过Xn接口发送给MN，相应地，由MN透传给终端设备。在一种实现方式中，上述SCG配置可以包括候选SCG的配置，其中，候选SCG的配置可以包含小区ID、无线承载配置、逻辑信道配置、RLC配置、MAC配置、物理层配置以及SCell配置。
需要说明的是，如上文介绍一个SCG可以包含一个或多个SCell，相应地，上述SCG配置可以包含一个或多个SCell配置，本申请实施例对此不作限定。
目前，为了帮助终端设备节约功耗，为SCG设置了两种不同的状态：去激活态和激活态。通常，终端设备接入SCG状态为去激活态的SCG后的功耗小于终端设备接入SCG状态为激活态的SCG后的功耗。在一些实现方式中，当终端设备接入的SCG的SCG状态为去激活态，终端设备在接入SCG之后的终端行为可以包括：停止监听PSCell发送的物理下行控制信道(physical downlink control channel，PDCCH)；执行MN和/或SN配置的测量；SCG内的SCell均处于去激活状态；不执行信道探测参考信号(sounding reference signal，SRS)的传输；不执行PSCell上的物理上行共享信道(physical uplink share channel，PUSCH)的传输；执行PSCell上的无线链路监测(radio link monitoring，RLM)和波束失败检测(beam failure detection，BFD)。
目前，SCG的SCG状态可以由网络设备通过无线资源控制(radio resource control，RRC)信令指示给终端设备。在一些实现方式中，网络设备可以通过在RRC重配置(RRC reconfiguration)请求或RRC恢复(RRC resume)请求的信息元素(information elements，IE)中包含“scg-state”字段指示来指示SCG的SCG状态。为例便于理解，下文以通过RRC重配置请求中的“scg-state”来指示SCG的SCG状态为例示出了RRC重配置请求的代码。

需要说明的是，上文介绍的CPAC配置、SCG配置、PScell配置以及SCG状态为去激活态时终端设备的行为都仅作为一种示例介绍，上述各个配置中包含的内容可以是现有通信协议中定义的，也可以是未来通信协议中更新的。另外，终端设备的行为也可以是现有协议定义的，也可以是未来通信协议中定义的，本申请实施例对此不作限定。
如上文介绍，终端设备基于网络设备提供的CPAC配置执行CPAC之后，都会释放相应的CPAC配置。当终端设备需要进行下一次CPAC时，网络设备需要重新为终端设备提供CPAC配置。如此以来，会增大网络设备传输CPAC配置所需的开销。然而，这种在终端设备每轮CPAC过程中，网络设备都为终端设备重新提供CPAC配置其实是不必要的。因为在一些情况下，终端设备进行CPA或CPC使用的CPAC配置可能相同，例如，当终端设备在小范围内移动时，终端设备每轮CPAC的过程使用的CPAC的配置相同。
因此，为了降低配置CPAC占用的开销，本申请实施例提供一种连续CPAC过程，即终端设备可以基于一个CPAC配置进行多轮CPAC。这样，网络设备无需在每轮CPAC的过程中为终端设备重新提供CPAC配置，有利于降低配置CPAC占用的开销。
在一些实现方式中，终端设备可以在一段时间内基于同一CPAC进行多轮CPAC。其中一段时间可以是预定义的，也可以是预配置的。在另一些实现方式中，在满足第一条件的情况下，终端设备可以基于同一CPAC配置进行多轮CPAC配置。其中，第一条件例如可以是终端设备的移动范围小于阈值。当然，本申请实施例对第一条件的内容不作具体限定。另外，上述第一条件可以是网络配置的，上述第一条件还可以是预定义的。
目前，传统的CPAC配置中通常会包含一个目标SCG的SCG状态，然而，在连续CPAC过程中，终端设备可能经过多轮CPAC过程切换到多个目标SCG，此时，终端设备无法获知多个目标SCG中每个目标SCG的SCG状态，导致终端设备、主节点、辅节点的理解不一致，从而终端设备与主节点、辅节点之间无法正常通信。
例如，假设多个目标SCG中的目标SCG1的SCG状态为激活态，由于网络设备为终端设备提供的CPAC配置中并不包含目标SCG1的SCG状态，导致终端设备无法获知，终端设备在接入目标SCG1后处于去激活态，在这种情况下，如果辅节点按照目标SCG1的SCG状态为激活态误判终端设备处于激活态，而通过目标SCG1向终端设备发送数据，则终端设备无法正常接收该数据，导致终端设备与辅节点之间的数据传输失败。
为了避免上述问题，本申请提供一种通信方法，当终端设备基于一个CPAC配置(又称“第一CPAC配置”)执行多轮CPAC变更了多个SCG时，这多个SCG中至少部分SCG的SCG状态可以由主节点MN或SN指示的，和/或多个SCG中至少部分SCG的SCG状态是预定义的。下文结合图2介绍本申请实施例中多个SCG的SCG状态。参见图2，在步骤S210中，终端设备基于第一SCG的SCG状态与SN通信，第一SCG属于上文中的多个SCG。
需要说明的是，当终端设备变更到多个SCG中的某一个SCG时，该SCG可以视为终端设备本次CPAC过程中的目标SCG，相应地，多个SCG中除目标SCG之外的其他SCG可以视为候选SCG。下文为了便于描述，本申请主要从终端设备变更到的多个SCG的角度来介绍，并不区分每轮CPAC过程中的目标SCG和候选SCG。
如上文所述本申请实施例中多个SCG的SCG状态的确定方式可以分为两种，在确定方式一中，多个SCG中至少部分的SCG状态由MN或SN指示的。在确定方式二中，多个SCG中至少部分的SCG状态为预定义的。下文针对上述两种方式进行介绍。
在确定方式一中，MN和SN可以通过向终端设备发送第一消息，供终端设备确定多个SCG的SCG状态。或者说，第一消息用于确定多个SCG的SCG状态。
上述通过第一消息确定多个SCG的SCG状态的方式有很多种，为了便于理解，下文主要结合三种方式介绍，本申请实施例并不限于以下三种方式。
方式一、第一消息可以包括多个SCG的SCG状态信息。
在一些实现方式中，上述第一消息可以包括多个SCG中每个SCG的标识与多个SCG中每个SCG的SCG状态信息之间的映射关系。在另一种实现方式中，上述第一消息还可以包含SCG状态列表，SCG状态列表包含多个SCG中每个SCG的状态。
例如，表1示出了SCG状态列表的一种可能的形式。在表1中，标识为ID1的SCG的SCG状态为去激活态，标识为ID2的SCG的SCG状态为激活态。
表1
SCG标识 SCG状态
ID1 去激活
ID2 激活
相应地，终端设备在介绍到上述第一信息后，可以基于第一消息中包含的多个SCG的SCG状态确定当前变更到的(或者准备变更的)SCG的SCG状态。即，上述方法还包括：终端设备基于第一消息确定第一SCG的SCG状态，第一消息中携带第一SCG的SCG状态。
方式二、第一消息可以仅指示多个SCG中第二SCG的SCG状态。
相应地，终端设备基于第二SCG的SCG状态确定多个SCG中其他SCG的SCG状态。在一些实现方式中，其他SCG的SCG状态可以与第二SCG的SCG状态相同，例如，当第二SCG的SCG状态为去激活态，其他SCG的SCG状态可以为去激活态。在另一些实现方式中，其他SCG的SCG状态可以与第二SCG的SCG状态相反，例如，当第二SCG的SCG为激活态，其他SCG的SCG状态可以为去激活态。
如上文所述，传统的方案中，网络设备在为终端设备提供新的CPAC配置后，会通过RRC信令为终端设备指示目标SCG的SCG状态，因此，为了兼容现有协议的规定，或者说减少对现有协议的修改，上述第二SCG可以是现有协议中网络设备通过RRC信令向终端设备指示的。
当然，如果不考虑兼容现有协议，在另一些实现方式中，上述第二SCG还可以是多次CPAC过程中终端设备第一次执行CPAC过程变更到的PSCell所属SCG，或者说，多次CPAC过程中终端设备最早执行CPAC过程变更到的PSCell所属SCG。例如，上述多次CPAC过程包含CPAC过程1、CPAC过程2以及CPAC过程3，其中CPAC过程1是多轮CPAC过程中终端设备第一次执行的CPAC过程，相应地，CPAC过程2是在终端设备执行CPAC过程1之后执行的CPAC过程，CPAC过程3是终端设备在执行CPAC过程2之后执行的CPAC过程。这样，上述第二SCG可以是CPAC过程1中终端设备变更的PSCell所属的SCG。
方式三、第一消息可以仅指示多个SCG中源PSCell所属的源SCG的SCG状态。
也就是说，多次CPAC过程中终端设备每次执行CPAC过程需要从源PSCell所属的源SCG变更到目标PSCell所属的目标SCG，其中，目标SCG的SCG状态是根据源SCG的SCG状态确定的。
相应地，终端设备基于源SCG的SCG状态确定多个SCG中其他SCG的SCG状态。在一些实现方式中，其他SCG的SCG状态可以与源SCG的SCG状态相同，例如，当源SCG的SCG状态为去激活态，其他SCG的SCG状态可以为去激活态。在另一些实现方式中，其他SCG的SCG状态可以与源SCG的SCG状态相反，例如，当源SCG的SCG为激活态，其他SCG的SCG状态可以为去激活态。
如上文所述，传统的方案中，网络设备在为终端设备提供新的CPAC配置后，会通过RRC信令为终端设备指示目标SCG的SCG状态，因此，为了兼容现有协议的规定，或者说为了减少对现有协议的修改，上述源SCG可以是现有协议中网络设备通过RRC信令向 终端设备指示的。
当然，如果不考虑兼容现有协议，在另一些实现方式中，上述源SCG还可以是多次CPAC过程中终端设备第一次执行CPAC过程中的源SCG，或者说，多次CPAC过程中终端设备最早执行CPAC过程中的源SCG。例如，上述多次CPAC过程包含CPAC过程1、CPAC过程2以及CPAC过程3，其中CPAC过程1是多轮CPAC过程中终端设备第一次执行的CPAC过程，相应地，CPAC过程2是在终端设备执行CPAC过程1之后执行的CPAC过程，CPAC过程3是终端设备在执行CPAC过程2之后执行的CPAC过程。这样，上述源SCG可以是CPAC过程1中终端设备在变更之前接入的SCG。
上文结合方式一至方式三，介绍了确定方式一中终端设备基于第一消息的确定多个SCG的SCG状态的方法，下文介绍第一消息的发送方式。如上文所述，第一消息可以是由MN发送的也可以是由SN发送的，因此，下文基于两种传输方式分别介绍。
在传输方式一中，MN向终端设备发送第一消息。
在一些实现方式中，MN可以将第一消息承载于SCG配置(又称“第二SCG配置”)中。例如SCG配置可以包含SCG1的配置信息1以及执行条件1，SCG2的配置信息2以及执行条件2，此时，可以在SCG1的配置信息1中添加SCG1的SCG状态(即上述第一消息中的部分信息)，可以在SCG1的配置信息1中添加SCG1的SCG状态(即上述第一消息中的部分信息)。在另一些实现方式中，MN可以将第一消息承载于单独的配置信息中发送给终端设备。
在传输方式二中，SN通过MN向终端设备发送第一消息。
相应地，MN可以不对第一消息进行处理，并直接将第一消息透传给终端设备。
在一些实现方式中，第一消息可以承载于SCG配置(又称“第一SCG配置”)中。例如SCG配置可以包含SCG1的配置信息1以及执行条件1，SCG2的配置信息2以及执行条件2，此时，可以在SCG1的配置信息1中添加SCG1的SCG状态(即上述第一消息中的部分信息)，可以在SCG1的配置信息1中添加SCG1的SCG状态(即上述第一消息中的部分信息)。在另一些实现方式中，SN可以将第一消息承载于单独的配置信息中通过MN发送给终端设备。
在确定方式二中，多个SCG中至少部分的SCG状态为预定义的。
上述确定方式二可以包括多个SCG中的部分或全部SCG的SCG状态可以为预定义的。在一些实现方式中，第一消息可以仅指示多个SCG中第三SCG的SCG状态，多个SCG中其他SCG状态可以是预定义的。或者说，多个SCG中其他SCG状态可以是默认的。相应地，终端设备基于第三SCG的SCG状态确定第三SCG的SCG状态，其他SCG的SCG状态可以基于预定义的SCG状态确定。例如，可以预定义其他SCG的SCG状态为去激活。又例如，可以预定义其他SCG的SCG状态为激活态。
在另一些实现方式中，多次CPAC过程中终端设备每次执行CPAC过程需要从源PSCell所属的源SCG变更到目标PSCell所属的目标SCG，其中，源SCG的SCG状态可以是预定义的，相应地，目标SCG的SCG状态是根据源SCG的SCG状态确定的。这种方式也可以理解为“终端自主确定SCG的SCG状态”。
相应地，终端设备基于源SCG的SCG状态确定多个SCG中其他SCG的SCG状态。在一些实现方式中，其他SCG的SCG状态可以与源SCG的SCG状态相同，例如，当源SCG的SCG状态为去激活态，其他SCG的SCG状态可以为去激活态。在另一些实现方式中，其他SCG的SCG状态可以与源SCG的SCG状态相反，例如，当源SCG的SCG为激活态，其他SCG的SCG状态可以为去激活态。
另外，假设第一SCG的SCG状态为去激活态，当终端设备接入第一SCG后，终端设备什么时候处于去激活态，本申请实施例对此不作限定。
在一些实现方式中，终端设备可以在向SN发送第一随机接入信道(random access  channel，RACH)之后，进入去激活态。即在终端设备通过第一SCG向SN发送第一随机接入信道RACH之后，终端设备基于去激活态与SN通信。
在另一些实现方式中，终端设备可以在向SN发送第二RACH，且竞争冲突成功解决之后，进入去激活态。即，若终端设备通过第一SCG向SN发送第二RACH，且竞争冲突成功解决，终端设备基于去激活态与SN通信。
在另一些实现方式中，终端设备可以在向SN发送第二RACH，竞争冲突成功解决且在预设时间段内未接收到指示第一SCG的SCG状态的指示信息之后，进入去激活态。即若终端设备通过第一SCG向SN发送第二RACH，竞争冲突成功解决，且在预设时间段内未接收到第二消息，终端设备基于去激活态与SN通信，第二消息用于指示第一SCG的SCG状态。
