具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
本申请实施例描述的网络架构以及业务场景是为了更加清楚地说明本申请实施例的技术方案，并不构成对本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
目前，相关标准组织正在研究NTN技术，NTN技术一般采用卫星通信的方式向地面用户提供通信服务。相比于地面的蜂窝通信网络，卫星通信具有很多独特的优点。首先，卫星通信不受用户地域的限制，例如一般的陆地通信不能覆盖海洋、高山、沙漠等无法搭设通信设备或由于人口稀少而不做通信覆盖的区域，而对于卫星通信来说，由于一颗卫星即可以覆盖较大的地面，加之卫星可以围绕地球做轨道运动，因此理论上地球上每一个角落都可以被卫星通信覆盖。其次，卫星通信有较大的社会价值。卫星通信在边远山区、贫穷落后的国家或地区都可以以较低的成本覆盖到，从而使这些地区的人们享受到先进的语音通信和移动互联网技术，有利于缩小与发达地区的数字鸿沟，促进这些地区的发展。再次，卫星通信距离远，且通信距离增大通讯的成本没有明显增加；最后，卫星通信的稳定性高，不受自然灾害的限制。
通信卫星按照轨道高度的不同分为LEO(Low-Earth Orbit，低地球轨道)卫星、MEO(Medium-Earth Orbit，中地球轨道)卫星、GEO(Geostationary Earth Orbit，地球同步轨道)卫星、HEO(High Elliptical Orbit，高椭圆轨道)卫星等等。目前阶段主要研究的是LEO和GEO。
1、LEO
低轨道卫星高度范围为500km～1500km，相应轨道周期约为1.5小时～2小时。用户间单跳通信的信号传播延迟一般小于20ms。最大卫星可视时间20分钟。信号传播距离短，链路损耗少，对用户终端设备的发射功率要求不高。
2、GEO
地球同步轨道卫星，轨道高度为35786km，围绕地球旋转周期为24小时。用户间单跳通信的信号传播延迟一般为250ms。
为了保证卫星的覆盖以及提升整个卫星通信系统的系统容量，卫星采用多波束覆盖地面，一颗卫星可以形成几十甚至数百个波束来覆盖地面；一个卫星波束可以覆盖直径几十至上百公里的地面区域。
在基于NTN技术构建的卫星网络架构中，通信卫星上的转发器是通信卫星的核心部件，它的作用是：将卫星上天线接收到的由地面站发送的电话、电报、传真、数据和图像等微弱的信号进行放大、变频，然后再通过发射天线把信号发射到另外的地点，以实现通过卫星进行两个地点的通信。由此看出，通信卫星的转发器数量的多少，是衡量某一卫星通信能力大小的标准。当代通信卫星已经有上百台转发器。目前，转发器有两种。一种是透明转发器，它对接收的信号除进行放大和变频外，不进行任何加工处理，只是单纯地完成转发任务，因此它对任何信号都是“透明”的。另一种是处理转发器(再生型)，它除了进行信号转发外，还具有信号处理的功能。进行信号处理的转发器有多种，随通信需要而选定，分别具有下述功能和特点：
(1)通过对信号解调和再生，可去掉上行线路中叠加在信号上的噪声，提高整个通信链 路的传输质量；
(2)通过对信号的解调和再调制，进行上下链路分开设计，可使上下链路实行不同的调制体制和多址方式，以降低传输要求和地面设备的复杂性；
(3)通过卫星上信号处理，可实现用户线路的信道、频率、功率和波束的动态分配，使卫星资源得到最佳利用；
(4)通过前向链路与返回链路信号处理器连接，可以实现移动用户之间只经一次转发通信，以减小空间传输时延；
(5)通过卫星上信号处理，可建立星际通信链路，以实现卫星星际联网。星际通信链路是指卫星与卫星之间的通信链路，其功能和特点是：地球上任意两点之间的通信可不通过地面网路而实现直达通信，有利于地面管理中心对整个卫星移动通信系统的统一管理。
请参考图1，其示出了一种卫星网络架构的示意图，该卫星网络架构中的通信卫星是透明转发(transparent payload)的卫星。如图1所示，该卫星网络架构包括：终端设备10、卫星20、NTN网关30、网络设备40和核心网设备50。
终端设备10和网络设备40之间可通过空口(如Uu接口)进行通信。在图1所示架构中，网络设备40可以部署在地面，终端设备10和网络设备40之间的上下行通信，可以通过卫星20和NTN网关30(通常位于地面)进行中转传输。以上行传输为例，终端设备10将上行信号发送给卫星20，卫星20将上述上行信号转发给NTN网关30，再由NTN网关30将上述上行信号转发给网络设备40，后续由网络设备40将上述上行信号发送给核心网设备50。以下行传输为例，来自核心网设备50的下行信号发送给网络设备40，网络设备40将下行信号发送给NTN网关30，NTN网关30将上述下行信号转发给卫星20，再由卫星20将上述下行信号转发给终端设备10。
请参考图2，其示出了另一种卫星网络架构的示意图，该卫星网络架构中的通信卫星是再生转发(regenerative payload)的卫星。如图2所示，该卫星网络架构包括：终端设备10、卫星20、NTN网关30和核心网设备50。
在图2所示架构中，网络设备40的功能集成在卫星20上，也即卫星20具备网络设备40的功能。终端设备10和卫星20之间可通过空口(如Uu接口)进行通信。卫星20和NTN网关30(通常位于地面)之间可通过SRI(Satellite Radio Interface，卫星无线接口)进行通信。
在图2所示架构中，以上行传输为例，终端设备10将上行信号发送给卫星20，卫星20将上述上行信号转发给NTN网关30，再由NTN网关30将上述上行信号发送给核心网设备50。以下行传输为例，来自核心网设备50的下行信号发送给NTN网关30，NTN网关30将上述下行信号转发给卫星20，再由卫星20将上述下行信号转发给终端设备10。
在上述图1和图2所示的网络架构中，网络设备40是用于为终端设备10提供无线通信服务的设备。网络设备40与终端设备10之间可以建立连接，从而通过该连接进行通信，包括信令和数据的交互。网络设备40的数量可以有多个，两个邻近的网络设备40之间也可以通过有线或者无线的方式进行通信。终端设备10可以在不同的网络设备40之间进行切换，也即与不同的网络设备40建立连接。
以蜂窝通信网络为例，蜂窝通信网络中的网络设备40可以是基站。基站是一种部署在接入网中用以为终端设备10提供无线通信功能的装置。基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在5G NR系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一名称可能会变化。为方便描述，本申请实施例中，上述为终端设备10提供无线通信功能的装置统称为基站或网络设备。
另外，本申请实施例中涉及的终端设备10，可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)，终端设备(terminal device) 等等。为方便描述，本申请实施例中，上面提到的设备统称为终端设备。
另外，以5G NTN网络为例，NTN网络中可以包括多颗卫星20。一颗卫星20可以覆盖一定范围的地面区域，为该地面区域上的终端设备10提供无线通信服务。另外，卫星20可以围绕地球做轨道运动，通过布设多个卫星20，可以实现对地球表面的不同区域的通信覆盖。
另外，在本申请实施例中，名词“网络”和“系统”通常混用，但本领域技术人员可以理解其含义。
当卫星20高速移动时，卫星20和NTN网关30之间的连接会发生切换，即从一个NTN网关切换到另一个NTN网关，该切换过程可称为馈电链路切换(feeder link switch)。在本申请中，馈电链路(feeder link)是指卫星20和NTN网关30之间的无线链路，也称为馈线链路或者其他名称，本申请实施例对此不作限定。
如图3所示，卫星20发生馈电链路切换，从第一NTN网关31切换至第二NTN网关32。
如果第一NTN网关31和第二NTN网关32连接到两个不同的网络设备(如基站，该基站可以是完整的基站，也可以是CU(Centralized Unit，集中单元))下的两个小区，或者连接到同一个网络设备下的两个小区，那么针对该卫星20覆盖区域内所有的终端设备，都需要在馈电链路切换完成后，从原来的小区切换到新的小区内。
如果第一NTN网关31和第二NTN网关32连接到同一个网络设备下的同一个小区，那么理论上终端设备不需要进行切换操作。
馈电链路切换有如下两种方案：一种是硬切换(hard switch)，即卫星先和原来的NTN网关断掉连接之后再和新的NTN网关进行连接，即break-before-make(断开后连接)；另一种是软切换(soft switch)，即卫星在保持原来的NTN网关连接时先与新的NTN网关建立连接，之后再断掉原来的NTN网关连接，即make-before-break(连接后断开)。
对于连接到同一个小区的两个NTN网关，卫星在这两个NTN网关间执行馈电链路切换(硬切换)的过程中，存在一段时间内卫星没有与任何NTN网关连接的情况，在这段时间内终端设备与网络设备(如基站)之间是无法进行上下行传输的。例如，在这段时间内网络设备无法向终端设备成功发送下行信号，包括SSB(Synchronization Signal and PBCH block，同步信号块)和CSI-RS(Channel State Information-Reference Signal，信道状态信息-参考信号)等，也无法成功接收来自终端设备的上行信号。因此，在这段时间内，如果终端设备和网络设备之间触发执行一些上下行传输，是不会成功的，反而导致终端设备和网络设备执行一些不必要的操作。
在本申请中，针对上述情形，也即对于连接到同一个小区的两个NTN网关，卫星在这两个NTN网关间执行馈电链路切换(硬切换)的过程中，终端设备和网络设备之间暂停进行上行传输和/或下行传输，从而避免终端设备和网络设备执行一些不必要的操作，降低系统开销。
下面，将通过几个实施例对本申请技术方案进行介绍说明。
请参考图4，其示出了本申请一个实施例提供的传输控制方法的流程图，该方法可应用于终端设备中，该方法可以包括如下几个步骤(410～420)：
步骤410，接收来自于网络设备的指示信息，该指示信息用于指示终端设备连接的卫星在第一NTN网关和第二NTN网关之间发生馈电链路切换，该第一NTN网关和第二NTN网关连接到网络设备下的同一个小区。
可选地，终端设备连接的卫星在第一NTN网关和第二NTN网关之间发生馈电链路切换，是指从第一NTN网关切换至第二NTN网关，且该切换过程为硬切换，也即卫星先断开与第一NTN网关之间的连接，然后再建立与第二NTN网关之间的连接。
网络设备在获知上述馈电链路切换的事件之后，向终端设备发送指示信息。可选地，该指示信息包括以下至少一项：第一时间信息、第二时间信息和时长信息。第一时间信息用于指示馈电链路切换的起始时刻，第二时间信息用于指示馈电链路切换的完成时刻，时长信息用于指示馈电链路切换的执行时长。示例性地，假设馈电链路切换的起始时刻为t1，完成时 刻为t2，执行时长为Δt，那么t2＝t1+Δt。
另外，在本申请实施例中，对承载上述指示信息的消息或信令不作限定。例如，终端设备接收来自于网络设备的系统消息，该系统消息中包括上述指示信息；或者，终端设备接收来自于网络设备的RRC(Radio Resource Control，无线资源控制)信令，该RRC信令中包括上述指示信息；或者，终端设备接收来自于网络设备的MAC(Media Access Control，媒体接入控制)CE(Control Element，控制元素)信令，该MAC CE信令中包括上述指示信息。
步骤420，根据指示信息，在馈电链路切换的过程中，暂停与网络设备之间进行上行传输和/或下行传输。
可选地，终端设备根据该指示信息，确定馈电链路切换的起始时刻和完成时刻，并在馈电链路切换的过程中(也即从馈电链路切换的起始时刻开始，到馈电链路切换的完成时刻为止的时间段内)，暂停与网络设备之间进行上行传输和/或下行传输。终端设备与网络设备之间可以只暂停上行传输，也可以只暂停下行传输，或者同时暂停上行传输和下行传输，本申请实施例对此不作限定。
在示例性实施例中，终端设备和网络设备之间实现暂停上下行传输的方式可以是：暂停运行与终端设备的MAC实体相关的第一定时器，该第一定时器用于控制MAC实体进行上行传输和/或下行传输。在该第一定时器的运行过程中，可能会触发执行上下行传输，通过暂停运行该第一定时器，即可避免触发执行上下行传输。
可选地，第一定时器包括但不限于以下至少一项：
1、预留给CG(Configured Grant，配置授权)的每个上行HARQ(Hybrid Automatic Repeat reQuest，混合自动重传请求)进程对应的配置授权定时器configuredGrantTimer；
配置授权定时器configuredGrantTimer用于控制预留给CG的上行HARQ进程的使用，例如对于预留给CG的上行HARQ进程，每次在使用该上行HARQ进程传输之后，启动configuredGrantTimer，在configuredGrantTimer运行期间内，无法在CG上再使用该上行HARQ进程传输，直至configuredGrantTimer超时后才能再在CG上使用该上行HARQ进程传输。
2、每个SR(Scheduling Request，调度请求)配置对应的SR禁止定时器sr-ProhibitTimer；
SR禁止定时器sr-ProhibitTimer定时器用于限制在PUCCH(Physical Uplink Control Channel，物理上行控制信道)中传输的SR信号，当该定时器正在运行时，是不能发送SR的，一旦该定时器超时，终端设备就可以重新发送SR，直到达到最大发送次数。
3、缓存状态报告重传定时器retxBSR-Timer；
对于缓存状态报告重传定时器retxBSR-Timer，在每一次上报BSR(Buffer Status Report，缓存状态报告)时启动或重启retxBSR-Timer。
4、缓存状态报告周期定时器periodicBSR-Timer；
对于缓存状态报告周期定时器periodicBSR-Timer，在每一次上报BSR，并且并不是所有的BSR都是长截短BSR(Long truncated BSR)或者短截短BSR(Short truncated BSR)时启动periodicBSR-Timer。
5、非连续接收非激活定时器drx-InactivityTimer；
非连续接收非激活定时器drx-InactivityTimer，是指配置的监控下行PDCCH(Physical Downlink Control Channel，物理下行控制信道)的定时器。终端设备在接收到指示上行的新传数据或者下行的新传数据的PDCCH后，启动drx-InactivityTimer，在drx-InactivityTimer运行期间，终端设备需要监听PDCCH。
6、每个下行HARQ进程对应的非连续接收下行重传定时器drx-RetransmissionTimerDL；
对于每一DL HARQ进程，终端设备等待DL重传调度的最大持续时间。如果定时器drx-HARQ-RTT-TimerDL超时，并且终端设备针对该下行HARQ进程的PDSCH(Physical Downlink Shared Channel，物理下行共享信道)反馈的是NACK(Negative Acknowledgment，否定确认)，则启动定时器drx-RetransmissionTimerDL。该定时器drx-RetransmissionTimerDL活动期间，终端设备保持激活态，以接收网络设备可能向该终端设备发送指示调度下行重传 或者新传的PDCCH。
7、每个上行HARQ进程对应的非连续接收上行重传定时器drx-RetransmissionTimerUL；
对于每一UL HARQ进程，终端等待UL重传的最大持续时间。如果定时器drx-HARQ-RTT-TimerUL超时，则启动定时器drx-RetransmissionTimerUL。该定时器drx-RetransmissionTimerUL活动期间，终端设备保持激活态，以接收网络设备可能向该终端设备发送指示调度上行重传或者新传的PDCCH。
8、非连续接收短周期定时器drx-ShortCycleTimer；
当配置了短周期DRX(Short DRX cycle)时，如果drx-InactivityTimer超时，或收到DRX Command MAC CE，则启动或重启drx-ShortCycleTimer，并开始使用短周期DRX。如果drx-ShortCycleTimer超时，则开始使用长周期DRX(Long DRX cycle)。
9、每个SCell(Secondary Cell，辅小区)对应的辅小区去激活定时器sCellDeactivationTimer；
辅小区去激活定时器sCellDeactivationTimer用于维护辅小区状态，例如在接收到指示激活辅小区的信令或在该辅小区中有数据传输时，启动或重启sCellDeactivationTimer，在sCellDeactivationTimer超时后，去激活该辅小区。
10、部分工作带宽非激活定时器bwp-InactivityTimer；
部分工作带宽非激活定时器bwp-InactivityTimer用于计时终端设备多长时间没有数据收发，在bwp-InactivityTimer超时之后切换至Default BWP(默认BWP)或者DL initial BWP(下行初始BWP)。
11、数据非激活定时器dataInactivityTimer；
当终端设备在监听控制信道期间收到了针对DTCH(Dedicated Transmission Channel，专用传输信道)、DCCH(Dedicated Control Channel，专用控制信道)或者CCCH(Common Control Channel，公共控制信道)的MAC SDU(Service Data Unit，服务数据单元)，或者发送了针对DTCH或者DCCH的MAC SDU时，终端设备启动或重启该定时器，在该定时器超时之前，终端设备连续监听控制信道。
12、用于波束失败检测的波束失败检测定时器beamFailureDetectionTimer；
终端设备在每次接收到波束故障实例的指示时都启动(或重启)该定时器，若该定时器超时则表明所接收到的波束故障实例不连续，终端设备的MAC层实体可以将波束失败计数器重新置零。
13、用于波束失败恢复的波束失败恢复定时器beamFailureRecoveryTimer；
该定时器用于监控波束故障恢复过程是否成功。
14、TAG(Timing Advance Group，定时提前组)对应的时间校准定时器timeAlignmentTimer。
终端设备在接收到TA Command(TA命令)之后启动该定时器，该定时器超时则认为终端设备处于上行失步状态。
可选地，如图5所示，上述步骤420之后还包括：
步骤430，在馈电链路切换完成后，恢复与网络设备之间进行上行传输和/或下行传输。
在馈电链路切换完成后，卫星与新的NTN网关已成功建立连接，因此可以正常为终端设备提供上下行传输服务。在本申请中，在馈电链路切换完成后，终端设备恢复与网络设备之间进行上行传输和/或下行传输，从而及时恢复上下行传输，保证用户体验。
可选地，如果在馈电链路切换的过程中暂停运行第一定时器，则在馈电链路切换完成后，恢复运行第一定时器，从而保证上下行传输的恢复。
下面，通过几个示例对第一定时器暂停运行和恢复运行的时刻进行介绍说明。
在一个示例中，指示信息包括第一时间信息和第二时间信息，第一时间信息用于指示馈电链路切换的起始时刻t1，第二时间信息用于指示馈电链路切换的完成时刻t2。终端设备可以在起始时刻t1，暂停运行第一定时器；另外，在完成时刻t2，恢复运行第一定时器。
在另一个示例中，指示信息包括第二时间信息，该第二时间信息用于指示馈电链路切换的完成时刻t2。终端设备可以在接收到指示信息的时刻，暂停运行第一定时器；另外，在完成时刻t2，恢复运行第一定时器。
在另一个示例中，指示信息包括第一时间信息和时长信息，第一时间信息用于指示馈电链路切换的起始时刻t1，时长信息用于指示馈电链路切换的执行时长Δt。终端设备可以在起始时刻t1，暂停运行第一定时器；另外，在馈电链路切换的完成时刻t1+Δt，恢复运行第一定时器。
如图6所示，在t1时刻，卫星20断开与第一NTN网关31的连接，开始馈电链路切换，从第一NTN网关31切换至第二NTN网关32；在t2时刻，卫星20完成馈电链路切换，与第二NTN网关32成功建立连接。相应地，在t1时刻，终端设备暂停运行MAC实体的第一定时器；在t2时刻，终端设备恢复运行MAC实体的第一定时器。通过上述方式，实现在馈电链路切换的过程中，终端设备和网络设备之间暂停进行上行传输和/或下行传输。
综上所述，本申请实施例提供的技术方案，对于连接到同一个小区的两个NTN网关，卫星在这两个NTN网关间执行馈电链路切换(硬切换)的过程中，终端设备和网络设备之间暂停进行上行传输和/或下行传输，从而避免终端设备和网络设备执行一些不必要的操作，降低系统开销。
