具体实施方式
为了方便理解本申请实施例的技术方案,首先给出本申请相关技术的简要介绍如下。
1、人工智能(artificial intelligence,AI)技术
AI在许多方面具有重要的应用潜力,例如复杂未知环境建模、学习,信道预测,智能信号生成与处理,网络状态跟踪与智能调度,网络优化部署等方面,对通信技术的研究有着重要的意义。引入AI技术的通信系统中,设备可以配置AI模型,通过AI模型使用基于AI的方法替换原有网络功能中基于数值公式的方法,从而提高网络资源使用效率,提升用户业务体验。
2、感知网络
感知网络指具有感知业务、网络、用户和终端设备,以及环境物体的属性与状态的系统,具体地,感知网络可以根据感知网络中的节点,例如传感器等设备,获取感知网络中的目标对象的信息,从而实现目标定位(包括测距、测速以及测角)、目标成像、目标检测和目标识别等功能。
终端设备在移动时,由于各种类型的遮挡,例如车辆,楼宇,树木等,均可能导致终端设备与被遮挡的基站之间的链路发生中断。为了保证数据的持续传输,可以为终端设备同时配置多个与不同基站间的连接,当其中一个连接中断时,可以利用其它的连接继续传输数据,这种终端设备需要同时维持至少两个连接的技术可以称为多连接技术。示例性的,如图1所示,终端设备同时维持与基站1和基站2之间的连接。在时刻1,这两个连接都正常工作。在时刻2,终端设备与基站1之间的连接因为终端设备被遮挡而中断,此时终端设备可以通过与基站2之间的连接传输数据。在时刻3,终端设备不再被遮挡,终端设备与基站1之间的连接恢复,终端设备同时与基站1和基站2保持连接。
但是,终端设备同时维持至少两个连接,会导致终端设备侧和基站侧的资源以及功率的开销显著增加。且目前主要由基站根据终端设备上报的信息控制终端设备是否维持多连接,这会导致额外的信令开销和时延。因此,如何在数据不中断传输的基础上,降低资源、信令、功率等开销和时延,是目前亟待解决的问题。

如图5所示,为本申请实施例提供的一种连接控制方法。图5中以第一网络设备、第二网络设备和终端设备作为该交互示意的执行主体为例来示意该方法,但本申请并不限制该交互示意的执行主体。例如,图5中的第一网络设备也可以是支持该第一网络设备实现该方法的芯片、芯片系统、或处理器,还可以是能实现全部或部分第一网络设备功能的逻辑模块或软件;图5中的终端设备也可以是支持该终端设备实现该方法的芯片、芯片系统、或处理器,还可以是能实现全部或部分终端设备功能的逻辑模块或软件;图5中的第二网络设备也可以是支持该第二网络设备实现该方法的芯片、芯片系统、或处理器,还可以是能实现全部或部分第二网络设备功能的逻辑模块或软件。该连接控制方法包括S501-S504:
S501、终端设备向第一网络设备发送第一请求消息,相对应的,第一网络设备接收第一请求消息。其中,第一请求消息用于请求与第二网络设备建立第二连接;第一请求消息包括第一时间信息;第一时间信息指示终端设备与第一网络设备建立的第一连接的中断时间。
S502、第一网络设备向第二网络设备发送第一请求消息,相对应的,第二网络设备接收到来自第一网络设备的第一请求消息。
S503、终端设备与第二网络设备建立第二连接。
S504、终端设备通过第二连接传输数据。
对于S501,本申请实施例中,终端设备与第一网络设备建立有第一连接。终端设备可以根据预测的第一连接的连接状态,确定是否向第一网络发送第一请求消息。若预测第一连接将要中断,终端设备会向第一网络设备发送第一请求消息,请求与第二网络设备建立新连接,该新连接可以称为第二连接。其中,第一请求消息包括指示第 一连接的中断时间的第一时间信息。
需要说明的是,本申请实施例的某些场景中,第一请求消息可以等同于第一时间信息,这种情况可以理解为第一请求消息仅包括第一时间信息,或者第一请求消息即为第一时间信息。该情况中,S501可以理解为终端设备向第一网络设备发送第一时间信息,第一网络设备根据第一时间信息获知终端设备请求与第二网络设备建立第二连接。
本申请实施例中,终端设备可以通过多种形式的第一时间信息指示第一连接的中断时间。例如,第一时间信息可以包括第一连接的中断时间的起始时刻(starting time)和结束时刻(ending time)。或者,第一时间信息可以包括第一连接的中断时间的起始时刻以及中断时长(duration)。其中,中断时长为从起始时刻到结束时刻的时长,即第一连接的中断时长。或者,第一时间信息可以包括第一连接的中断时间的结束时刻以及中断时长。
需要说明的是,本申请实施例并不限制第一时间信息的时间单位,例如,可以为时隙(slot)、符号(symbol)或者迷你时隙(mini-slot)等时间单位,也可以为秒,毫秒或微秒时间单位。以下以第一时间信息的时间单位为时隙,进行示例性的说明。若第一时间信息包括第一连接的中断时间的起始时刻和/或结束时刻,起始时刻和/或结束时刻可以通过时隙索引指示。若第一时间信息包括中断时长,中断时长可以通过时隙的数量指示。
以下介绍如何预测第一连接的连接状态。
一种可能的实现中,可以由终端设备自身对第一连接的连接状态进行预测,得到预测结果。或者,终端设备可以从其他设备处获取预测结果。其中,预测结果指示预测的第一连接的连接状态。
一种可能的实现中,预测的第一连接的连接状态可以是预测的第二预设时长后的第一连接的连接状态。例如,第二预设时长为1分钟,终端设备可以预测1分钟后第一连接的连接状态。可选的,第一连接的连接状态可以周期性进行预测。例如,终端设备可以每隔1分钟,预测一次第一连接的连接状态。
一种可能的实现中,可以以概率形式预测第一连接的连接状态。在第一连接的连接状态包括中断和正常工作的情况下,可以分别预测第一连接被中断的概率和正常工作的概率。或者,可以预测第一连接被中断的概率,第一连接正常工作的概率可以根据第一连接被中断的概率确定。或者,可以预测第一连接正常工作的概率,第一连接被中断的概率可以根据第一连接正常工作的概率确定。例如,终端设备预测第一连接的连接状态有80%的概率为中断,或者,也可以称为终端设备预测第一连接被中断的概率为80%。
在以概率形式预测第一连接的连接状态的场景中,第一时间信息指示的第一连接的中断时间可以为第一连接被中断的概率大于或等于第二预设门限的时间,其中,第二预设门限可以根据实际需求配置。例如,第二预设门限为80%,终端设备预测第一连接在时隙1被中断的概率为85%,在时隙2被中断的概率为90%,在时隙3被中断的概率为30%,则终端设备预测的第一连接的中断时间为时隙1至时隙2。
又一种可能的实现中,在第一连接的连接状态包括中断和正常工作的情况下,可 以预测第一连接的连接状态是被中断还是正常工作,从而确定第一连接的中断时间。
可选的,本申请实施例中,第一连接的连接状态可以是根据AI模型和/或感知网络进行预测的。换言之,第一时间信息,或者说第一连接的中断时间可以是根据AI模型和/或感知网络确定的。
以下介绍本申请实施例中,根据AI模型和/或感知网络确定第一连接的中断时间的可能实现方式。
一种可能的实现方式中,可以根据感知网络获取表征终端设备的移动性的辅助信息,并根据辅助信息对第一连接的连接状态进行预测,确定第一连接的中断时间。例如,辅助信息可以包括终端设备的位置信息、移动方向信息以及终端设备的移动速度信息中的至少一项信息。其中,可以由终端设备通过感知网络获取辅助信息,并根据辅助信息进行预测,或者,也可以由其他设备通过感知网络获取辅助信息,并根据辅助信息进行预测,终端设备可以从该设备处获取预测结果。
另一种可能的实现方式中,由AI模型对第一连接的连接状态进行预测,并输出预测结果,从而根据AI模型输出的预测结果,确定第一连接的中断时间。可选的,输入AI模型的,用于获取预测结果的信息,可以是用于表征终端设备的移动性的辅助信息。进一步地,输入AI模型的辅助信息可以是通过感知网络获取的,或者,也可以是通过其他网络,例如通信网络获取的,本申请实施例对此不做限制。其中,AI模型可以是配置在终端设备上的,或者,也可以是配置在其他设备上的,终端设备可以从配置有AI模型的设备处获取预测结果。
可选的,若根据AI模型和/或感知网络确定第一时间信息,为了确保第二连接的建立需求的可靠性,终端设备向第一网络设备发送第一请求消息的条件可以包括:AI模型和/或感知网络的准确度大于或等于第一预设门限。换言之,在AI模型和/或感知网络的准确度大于或等于第一预设门限的情况下,终端设备向第一网络设备发送第一请求消息。其中,第一预设门限可以根据实际需求设置。
可选的,第一请求消息还可以包括第一时间点,第一时间点为终端设备期望的第二连接建立完成的时刻。
本申请实施例中,期望的可以理解为希望实现的,希望达到的,或者预期的目标。例如,第一时间点可以为终端设备希望的第二连接建立完成的目标时刻。
可选的,终端设备期望的时刻可以是终端设备根据预配置的算法和/或模型确定的。一种可能的实现方式中,终端设备期望的时刻可以是根据AI模型和/或感知网络确定的。
本申请实施例中,第一时间点的时间单位可以参考上文对第一时间信息的时间单位的介绍。示例性的,假设第一时间点的时间单位为时隙,第一时间点可以通过时隙索引指示,第一时间点可以为该时隙索引对应的时隙的起始时刻或者结束时刻,其中,可选的,可以通过预定义或者信令配置的方式,定义第一时间点应该为时隙的起始时刻还是时隙的结束时刻。需要说明的是,下文中出现的时间点,例如第二时间点,其时间单位也可以参考此处的介绍,在此统一说明,往后不再赘述。
本申请实施例中,预定义的可以理解为协议预定义的,信令配置的可以理解为由高层或者物理层信令配置的。高层信令例如可以包括无线资源控制(radio resource  control,RRC)信令、媒体接入控制(medium access control,MAC)控制元素(control element,CE)、无线链路控制(radio link control,RLC)信令等。物理层信令例如可以包括物理下行控制信息(downlink control information,DCI)、通过下行物理层信道传输的信令等,物理下行信道例如可以为物理下行控制信道(physical downlink control channel,PDCCH)或者物理下行共享信道(physical downlink shared channel,PDSCH)等。
可选的,为了保证数据可以正常传输,第一时间点可以早于或者等于第一连接的中断时间的起始时刻。第一网络设备可以根据第一请求消息获知终端设备期望的第二连接建立完成的时刻,具体在下文介绍S502时进行说明,此处不展开介绍。
可选的,第一请求消息还可以包括第二网络设备的标识,以使第一网络设备确定第二网络设备。
以下介绍终端设备如何向第一网络设备发送第一请求消息。
一种可能的实现方式中,终端设备可以从预定义或者信令配置的一个或多个第一时频资源中,确定出目标第一时频资源,并通过目标第一时频资源向第一网络设备发送第一请求消息。
可选的,终端设备可以根据第一时间点和/或第一网络设备处理第一请求消息所需的时间,从预定义或者信令配置的一个或多个第一时频资源中确定目标第一时频资源。其中,第一网络设备处理第一请求消息所需的时间,指第一网络设备处理第一请求消息所需的时长。第一网络设备处理第一请求消息所需的时间可以是终端设备预测得到的,例如可以通过AI模型和/或感知网络进行预测。或者第一网络设备处理第一请求消息所需的时间可以是预定义或者信令配置的。其中,可以理解的是,若终端设备可以根据第一时间点确定目标第一时频资源,目标第一时频资源的时域位置应该早于第一时间点。
示例性的,假设终端设备预配置了3个第一时频资源,在终端设备根据第一时间点和第一网络设备处理第一请求消息所需的时间确定目标第一时频资源的情况下,若第一网络设备处理第一请求消息所需的时间较长,终端设备可以从这3个第一时频资源中,选择时域上最早的第一时频资源,即第一个第一时频资源作为目标第一时频资源,防止第一网络设备来不及在第一时间点之前处理完第一请求消息。若第一网络设备处理第一请求消息所需的时间较短,终端设备可以从这3个第一时频资源中选择第二个第一时频资源或者第三个第一时频资源作为目标第一时频资源。
进一步地,终端设备在确定目标第一时频资源时,还可以考虑第一时频资源有没有被占用。例如,第一时频资源有没有被配置用于传输其他数据或信令。
另一种可能的实现方式中,终端设备可以通过用于传输上行数据的资源,向第一网络设备发送第一请求消息。例如,第一请求消息可以承载在MAC CE中。
可选的,终端设备向第一网络设备发送第一时间信息后,若预测得到的第一连接的中断时间有更新,终端设备可以再次向第一网络设备发送新的第一时间信息,新的第一时间信息指示更新后的第一连接的中断时间。进一步地,第一网络设备可以向第二网络设备发送新的第一时间信息。例如,终端设备第一次对第一连接的连接状态进行预测,得到第一连接的中断时间为时隙1至时隙5,终端设备向第一网络设备发送 指示第一连接的中断时间为时隙1至时隙5的第一时间信息。之后终端设备再次对第一连接的连接状态进行预测,得到的第一连接的中断时间更新为时隙1至时隙6,终端设备再向第一网络设备发送指示第一连接的中断时间更新为时隙1至时隙6的第一时间信息。
可选的,终端设备请求建立第二连接的第二网络设备,可以是在第一连接的中断时间内,预测与终端设备建立的新连接可以正常工作的网络设备。例如,终端设备预配置有一个或多个备选网络设备,终端设备确定第一连接的中断时间后,可以预测若与备选网络设备建立新连接,建立的新连接在第一连接的中断时间内能否正常工作。从而终端设备可以从备选网络设备中,选择预测出在第一连接的中断时间内,建立的新连接可以正常工作的备选网络设备作为第二网络设备。其中,预测建立的新连接能否在第一连接的中断时间内正常工作的具体实现,可以参考上文对如何预测第一连接的连接状态的介绍,在此不再赘述。
对于S502,第一网络设备接收到第一请求消息后,向第二网络设备发送第一请求消息,以使第二网络设备获知终端设备请求建立第二连接。
可选的,在第一请求消息包括第一时间点的情况下,第一网络设备可以根据第一时间点,确定终端设备期望的第二连接建立完成的时刻,从而根据第一时间点确定用于发送第一请求消息的第二时间点,在第二时间点向第二网络设备发送第一请求消息。其中,可以理解的是,第二时间点早于第一时间点。示例性的,如果第一时间点为时隙3,换言之,终端设备期望第二连接在索引为3的时隙内建立完成。第一网络设备可以根据第一时间点,在索引为1的时隙内向第二网络设备发送第一请求消息。
或者,第一网络设备也可以根据接收到第一请求消息的时间,确定何时向第二网络设备发送第一请求消息。例如,第一网络设备可以以接收到第一请求消息的时刻为起始时间点,在预定义的一段时长之后,向第二网络设备发送第一请求消息。
可选的,第一网络设备向第二网络设备发送第一请求消息后,第二网络设备若同意与终端设备建立第二连接,第二网络设备可以向第一网络设备发送第一确认消息,第一确认消息指示第二网络设备同意与终端设备建立第二连接。第一网络设备收到第一确认消息后,向终端设备发送第一确认消息。其中,第一确认消息也可以称为第一请求消息的响应消息。
可选的,第一确认消息可以包括用于终端设备建立第二连接的配置信息和/或资源。例如,第一确认消息可以包括第二网络设备的标识信息、终端设备在第二网络设备处的小区-无线网络临时标识符(cell-radio network tempory identity,Cell-RNTI)、第二网络设备的安全算法、第二网络设备的随机接入信道(random access channel,RACH)资源信息、第二网络设备的参考信号配置信息、同步信号块(synchronization signal block,SSB)的信息,以及第二网络设备的RACH资源信息与第二网络设备的参考信号配置信息的关联信息等中的一项或多项。其中,参考信号配置信息可以包括:探测参考信号(sounding reference signal,SRS)的配置信息,或者信道状态信息参考信息(channel state information reference signal,CSI-RS)的配置信息。
进一步地,在第一请求消息包括第一时间点的情况下,第一网络设备可以根据第一时间点,确定用于发送第一确认消息的第三时间点,在第三时间点向终端设备发送 第一确认消息。其中,可以理解的是,第三时间点早于第一时间点。示例性的,如果第一时间点为索引为3的时隙,换言之,终端设备期望第二连接在索引为3的时隙内建立完成。第一网络设备在收到第一确认消息后,可以根据第一时间点,在索引为2的时隙内向终端设备发送第一确认消息。
或者,第一网络设备也可以根据接收到第一确认消息的时间,确定何时向终端设备发送第一请求消息。例如,第一网络设备可以以接收到第一确认消息的时刻为起始时间点,在预定义的一段时长之后,向终端设备发送第一确认消息。
本申请实施例中,第一网络设备在接收到第一请求消息后,可以根据第一时间信息,在第一时间信息指示的第一连接的中断时间内执行不同的行为。
可选的,第一网络设备可以在第一连接的中断时间内,停止向终端设备发送数据,以达到节约功耗和资源的目的。
或者,第一网络设备可以在第一连接的中断时间内,依然向终端设备发送数据,防止由于预测不准确,在第一时间信息指示的第一连接的中断时间内第一连接实际未中断,导致数据传输失败。或者防止因为第二连接建立失败,导致数据传输失败。
另一方面,可选的,终端设备在第一连接的中断时间内,可以停止通过第一连接接收数据。或者,终端设备也可以在第一连接的中断时间内,依然对第一网络设备的数据进行接收。

如图7所示,为本申请实施例提供的另一种连接控制方法。图7中以第二网络设备和终端设备作为该交互示意的执行主体为例来示意该方法,但本申请并不限制该交互示意的执行主体。例如,图7中的终端设备也可以是支持该终端设备实现该方法的芯片、芯片系统、或处理器,还可以是能实现全部或部分终端设备功能的逻辑模块或软件;图7中的第二网络设备也可以是支持该第二网络设备实现该方法的芯片、芯片系统、或处理器,还可以是能实现全部或部分第二网络设备功能的逻辑模块或软件。该连接控制方法包括S701-S703:

S702、第二连接从第一模式切换至第二模式。
S703、终端设备在第二模式下通过第二连接传输数据。
对于S701,本申请实施例中,终端设备与第一网络设备建立有第一连接。终端设备可以根据预测的第一连接的连接状态,确定是否向第一网络发送第三请求消息。若预测第一连接将要中断,终端设备会向第二网络设备发送第三请求消息,请求将与第二网络设备建立的第二连接从第一模式切换至第二模式。其中,第三请求消息包括指示第一连接的中断时间的第二时间信息。
本申请实施例中,终端设备工作在第二模式下的功率高于终端设备工作在第一模式下的功率。因此,也可以将第二模式称为正常功率模式,将第一模式称为节约功率模式。其中,这里的功率(终端设备工作在第二模式下或者工作在第一模式下的功率)可以包括终端设备发送数据的功率和/或终端设备接收数据的功率。
本申请实施例中,第一模式可以理解为终端设备的功率低于正常功率模式下的功率的模式。其中正常功率模式下的功率指当终端设备处于连接态(connected)时进行上行数据发送或者下行数据接收时的功率。第一模式可以包括多种子模式,例如可以包括空闲态、去激活态(inactive)以及连接态。在上述三种状态下,终端设备可以根据网络设备配置的不连续接收(discontinuous reception,DRX)机制,周期性地在某些时候进入睡眠状态(sleep mode),不去监测寻呼(paging)消息或者PDCCH,而需要监测的时候,则从睡眠状态中唤醒(wake up),从而使终端设备达到省电的目的。
本申请实施例中,第一连接可以保持为第二模式。
需要说明的是,本申请实施例的某些场景中,第三请求消息可以等同于第二时间信息,这种情况可以理解为第三请求消息仅包括第二时间信息,或者第三请求消息即为第二时间信息。该情况中,S701可以理解为终端设备向第二网络设备发送第二时间信息,第二网络设备根据第二时间信息获知终端设备请求将第二连接切换至第二模式。
S701中,第二时间信息可以参考上文对S501中,第一时间信息的介绍,在此不再赘述。
需要说明的是,S701中,第一连接的中断时间可以为第一连接被中断的概率大于或等于第四预设门限的时间。其中,第四预设门限可以与S501中的第二预设门限相同,也可以不同。
可选的,终端设备还可以向第一网络设备发送第二时间信息,第一网络设备可以根据第二时间信息确定第一连接的中断时间。进一步地,第一网络设备可以根据第二时间信息,在第一连接的中断时间内执行不同的行为:停止通过第一连接向终端设备发送数据,或者,依然通过第一连接向终端设备发送数据。
S701中,如何预测第一连接的连接状态,可以参考上文对S501中,如何预测第一连接的连接状态的介绍,在此不再赘述。

可选的,终端设备可以根据第八时间点和/或第二网络设备处理第三请求消息所需的时间,从预定义或信令配置的一个或多个第三时频资源中确定目标第三时频资源。其中,第二网络设备处理第三请求消息所需的时间,指第二网络设备处理第三请求消息所需的时长。第三网络设备处理第三请求消息所需的时间可以是终端设备预测得到的,例如可以通过AI模型和/或感知网络进行预测。或者第二网络设备处理第三请求消息所需的时间可以是预定义或者信令配置的。
其中,终端设备根据第八时间点确定目标第三时频资源时,目标第三时频资源的时域位置早于第八时间点。
进一步地,终端设备在确定目标第三时频资源时,还可以考虑第三时频资源有没有被占用。例如,第三时频资源有没有被配置用于传输其他数据或信令。

例如,终端设备第一次对第一连接的连接状态进行预测,得到第一连接的中断时间为时隙1至时隙5,终端设备向第一网络设备和第二网络设备发送指示第一连接的中断时间为时隙1至时隙5的第二时间信息。之后终端设备再次对第一连接的连接状态进行预测,得到的第一连接的中断时间更新为时隙1至时隙6,终端设备再向第一网络设备和第二网络设备发送指示第一连接的中断时间更新为时隙1至时隙6的第二时间信息。
对于S702,终端设备向第二网络设备发送第三请求消息之后,终端设备和第二网络设备可以将第二连接从第一模式切换至第二模式。
具体地,终端设备侧和第二网络设备侧均将第二连接从第一模式切换至第二模式,从而使第二连接从第一模式切换至第二模式。可以理解的是,在终端设备和第二网络设备两侧,第二连接均已经切换至第二模式,则可以称为切换完成。
可选的,终端设备在向第二网络设备发送第三请求消息之后,若第二网络设备同意将第二连接切换至第二模式,第二网络设备可以向终端设备发送第三确认消息,第三确认消息指示第二网络设备同意将第二连接切换至第二模式。其中,第三确认消息也可以称为第三请求消息的响应消息。在终端设备接收到第二确认消息之后,终端设备将第二连接从第一模式切换至第二模式。
进一步地,在第三请求消息包括第八时间点的情况下,第二网络设备可以根据第八时间点,确定用于发送第三确认消息的第十一时间点,在第十一时间点向终端设备发送第三确认消息。其中,可以理解的是,第十一时间点早于第八时间点。示例性的,如果第八时间点为索引为3的时隙,换言之,终端设备期望第二连接在索引为3的时隙内切换至第二模式。第二网络设备在收到第三请求消息后,可以根据第八时间点,在索引为2的时隙内向终端设备发送第三确认消息。
可选的,第二网络设备可以在收到第三请求消息后,也可以不向终端设备发送第三确认消息,而是直接根据第二时间信息指示的第一连接的中断时间,确定将第二连接切换至第二模式的时刻。示例性的,如果第二时间信息指示第一连接的中断时间为时隙2至时隙5,第二网络设备在收到第二时间信息后,可以根据第二时间信息,在时隙2内将第二连接切换至第二模式。或者,在第三请求消息包括第八时间点的情况下,第二网络设备可以根据第八时间点确定将第二连接切换至第二模式的时刻,例如可以直接将第八时间点作为将第二连接切换至第二模式的时刻,或者将位于第八时间点之前,且与第八时间点之间的时间间隔为一定间隔的时间点作为第二连接切换至第二模式的时刻。

或者,在终端设备不向第二网络设备发送第四请求消息的情况中,第二网络设备可以根据第三请求消息中,第二时间信息指示的第一连接的中断时间,确定用于将第二连接切换至第一模式的第十三时间点。例如,第二时间信息指示第一连接的中断时间的结束时刻为时隙4,为了保证数据传输不会中断,第二网络设备可以在时隙5将第二连接切换至第一模式,即第十三时间点为时隙4。
可选的,第二网络设备可以向终端设备发送第四确认消息,第四确认消息指示第二网络设备同意将第二连接切换至第一模式。第四确认消息可以是第四请求消息的响应消息,也可以是第二网络设备主动发送的指示消息(例如,第二网络设备根据第一连接的中断时间确定用于将第二连接切换至第一模式的第十三时间点后,可以向终端设备发送第四确认消息指示第二网络设备会在第十三时间点将第二连接切换至第一模式)。终端设备可以在收到第四确认消息后,将第二连接切换至第一模式。进一步地,若第四确认消息是第四请求消息的响应消息,且第四请求消息包括第九时间点,第二网络设备可以根据第九时间点,确定向终端设备发送第四确认消息的时刻。

S1004-S1006中,t3-2、t3-3和t3-4可以是第一网络设备和第三网络设备根据第十时间点确定的。
S1007、在时刻3-5(t3-5),终端设备与第三网络设备之间的第二模式的第三连接建立完成。
S1008、在t4-1’,第一连接开始中断,终端设备通过第二模式的第三连接与第三网络设备传输数据。其中,t4-1’可以与t4-1为同一时刻,也可以为不同时刻。
