本申请实施例中涉及的“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a、b或c中的至少一项(个)， 可以表示：a，b，c，a和b，a和c，b和c，或a、b和c，其中a、b、c中的每一个本身可以是元素，也可以是包含一个或多个元素的集合。
以及，除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。例如，第一信息和第二信息，只是为了区分不同的信息，而并不是表示这两种信息的内容、优先级、发送顺序或者重要程度等的不同。
本申请实施例中出现的“连接”是指直接连接或者间接连接等各种连接方式，以实现设备间的通信，本申请实施例对此不做任何限定。
本申请实施例结合终端、卫星和网络设备描述了各个实施例。下面对其进行具体介绍。
具体的，本申请实施例中的终端可以是用户设备(user equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、智能终端、无线通信设备、用户代理或用户装置。终端还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、中继设备、车载设备、可穿戴设备、下一代通信系统例如NR网络中的终端或者未来演进的公用陆地移动通信网络(public land mobile network，PLMN)中的终端等，对此不作具体限定。
进一步的，终端可以部署在陆地上，包括室内或室外、手持、穿戴或车载；可以部署在水面上(如轮船等)；还可以部署在空中(如飞机、气球和卫星等)。
进一步的，终端可以是手机(mobile phone)、平板电脑、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self driving)中的车载设备、远程医疗(remote medical)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备或智慧家庭(smart home)中的无线终端设备等。
具体的，本申请实施例中的卫星可以是载有弯管有效载荷(bent pipe payload)或再生有效载荷(regenerative payload)信号发射机的航天器，其通常运行在300至1500km之间的高度的近地轨道(low earth orbit，LEO)、在7000至25000km之间的高度的中地轨道(medium earth orbit，MEO)、在35786km的高度的同步地球轨道(geostationary earth orbit，GEO)或者在400至50000km之间的高度的高椭圆轨道(high elliptical orbit，HEO)。也就是说，卫星按照轨道高度的不同可以为LEO卫星、MEO卫星、GEO卫星或者HEO 卫星等。
进一步的，NTN通信系统中的卫星通常会在地面上产生一个或多个波束(beam，或者称为beam footprint)，并且该一个或多个波束在地面上会形成小区。
具体的，本申请实施例中的网络设备(包括第一网络设备和第二网络设备)可以是全球移动通讯(global system of mobile communication，GSM)通信系统或者码分多址(code division multiple access，CDMA)通信系统中的基站(base transceiver station，BTS)、宽带码分多址(wideband code division multiple access，WCDMA)通信系统中的基站(nodeB，NB)、长期演进(long term evolution，LTE)通信系统中的演进型基站(evolutional node B，eNB或eNodeB)或者新无线(new radio，NR)通信系统中的基站(gNB)。网络设备还可以是无线局域网WLAN中的接入点(access point，AP)、中继站、未来演进的PLMN网络中的网络设备或者NTN通信系统中的网络设备等。
需要说明的是，在一些网络部署中，gNB可以包括集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，而gNB还可以包括有源天线单元(active antenna unit，AAU)。其中，CU可以实现gNB的部分功能，而DU也可以实现gNB的部分功能。比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)层和分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能；DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、媒体接入控制(medium access control，MAC)层和物理(physical，PHY)层的功能。另外，AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因此，高层信令(如RRC层信令)可以认为是由DU发送的，或者由DU+AAU发送的。可以理解的是，网络设备可以包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，对此不做具体限制。
示例性的，本申请实施例应用的通信系统，如图1所示。非地面网络通信系统10可以包括终端甲110、第一网络设备120、第二网络设备130、第一小区140、第二小区150、卫星160、卫星170。其中，终端甲110、第一网络设备120以及第二网络设备130可以位于地球表面，而卫星160、卫星170位于地球轨道。卫星160可以向信号覆盖的目标地理区域提供第一小区140进行通信服务，并且可以与位于信号覆盖区域内的终端甲110进行通信，卫星170可以向信号覆盖的目标地理区域提供第二小区150进行通信服务，并且可以与位于信号覆盖区域内的终端甲110进行通信，且第二小区150是第一小 区140之后第一个覆盖该目标地理区域的小区。
结合图1所示的通信系统，对本申请实施例的信息传输方法进行介绍。
示例的，图2A为本申请实施例提供的一种信息传输方法的流程示意图，如图2A所示，该信息传输具体包括如下步骤：
S101、第一网络设备在目标地理区域的第一小区切换到第二小区之前，向第二网络设备提供辅助信息。
S102、所述第二网络设备在所述第一小区切换到所述第二小区之前，接收来自所述第一网络设备的辅助信息。
作为一种具体的实施方式，所述提供辅助信息是指传输所述辅助信息到目标结点。
其中，所述第一小区为所述第一网络设备对应的小区，所述第二小区为第二网络设备对应的小区。所述目标地理区域可以是地球表面的任意一个第一小区和第二小区均能覆盖的地理区域。
目标地理区域的第一小区切换到第二小区是指为目标区域提供服务的小区从第一小区切换到第二小区。
可见，本示例中，通过在所述第一小区切换到所述第二小区之前完成第一网络设备和第二网络设备之间的信息传输，实现第二小区为目标地理区域提供服务之后，处于该目标地理区域中的终端与第二网络设备之间的数据交互过程中原本需要第二网络设备获取的辅助信息在所述第一小区切换到所述第二小区之前已经获取完成，可以直接使用，减少终端与第二网络设备之间的数据交互流程，节约终端的能耗，同时，节省了无线资源。
其中，所述辅助信息包括但不限于第一通知信息和/或第三通知信息；所述第一通知信息包括上下文信息和/或缓存状态报告信息，所述上下文信息包括在所述第一小区中处于连接态或INACTIVE态的至少一个终端的至少一个上下文中的部分或者全部，所述缓存状态报告信息包括在所述至少一个终端的至少一个缓存状态报告中的部分或者全部，所述缓存状态报告是指所述终端在所述第一小区停止向所述目标地理区域提供服务的时刻对应的缓存状态报告；所述第三通知信息用于指示来自所述第一小区的终端的RRC重建立请求不携带所述第一小区的标识信息。
示例性地，第一小区的标识信息可以是第一小区的物理小区标识PCI，也可以是第一小区的全球小区标识CGI，或其它形式的第一小区的标识信息。
其中，对所述至少一个终端的数量不作具体限定，可以理解的是，一个所述终端对应一个上下文和/或一个缓存状态报告。
进一步的，所述缓存状态报告可以包括但不限于待传输数据量。
在一个可能的实施例中，所述向第二网络设备提供辅助信息的实现方式可以是一次向第二网络设备发送所述第一通知信息；或者，分多次向第二网 络设备发送所述第一通知信息。其中，所述多次可以是3次，5次，10次，100次，等等，不做具体限定，且每次发送的第一通知信息中的上下文数量和/或缓存状态报告数量不作具体限定。
在一个可能的实施例中，所述至少一个上下文中的部分或者全部中每个上下文的发送时机在该上下文对应的终端执行所述第一小区的无线链路失败RLF相关操作的结束时刻之前。
举例来说，所述至少一个终端包括终端甲，终端乙，终端丙，终端丁。所述至少一个上下文包括与该终端甲对应的上下文A，该终端乙对应的上下文B，该终端丙对应的上下文C，该终端丁对应的上下文D。若该终端甲向所述第一网络设备执行RLF相关操作的结束时刻为时刻1，该终端乙向所述第一网络设备执行RLF相关操作的结束时刻为时刻1，该终端丙向所述第一网络设备执行RLF相关操作的结束时刻为时刻2，该终端丁向所述第一网络设备执行RLF相关操作的结束时刻为时刻2；则上下文A和上下文B的发送时机在时刻1之前，上下文C的发送时机在时刻2之前，上下文D的发送时机在时刻3之前。
需要说明的是，若第一网络设备在终端执行所述第一小区的无线链路失败RLF相关操作的结束时刻之前，向第二网络设备发送终端的上下文，则第二网络设备不再需要在该终端与第二小区的RRC重建立过程向第一网络设备请求该终端的上下文。获取该终端的上下文，使得该终端与第二小区的RRC重建立过程中，减少第二网络设备向第一网络设备请求终端上下文的流程，提升终端与第二小区的RRC重建立的快捷性。
在具体的应用场景中，如图2B所示出的，UE处于目标地理区域中，该目标地理区域的小区Cell 1切换到小区Cell 2的流程，从T1时刻之后，T1时刻为Cell 1停止服务该目标地理区域的时刻，UE会进入与Cell 1所对应的基站的RLF流程，在该RLF流程完成之后，该UE会进入与Cell 2的RRC重建立流程，在UE进入RLF流程和RRC重建立流程，UE不能传输数据，Cell 1对应的基站在该UE执行该基站的RLF相关操作的结束时刻T2之前，将该UE的上下文发送到Cell 2对应的基站，因为Cell 2对应的基站已经从Cell 1对应的基站处获取到该UE的上下文，参考图2C，图2C中，Cell 1对应的基站在T2之前，未将该UE的上下文发送到Cell 2对应的基站，则在该UE与Cell 2的RRC重建立流程中，Cell 2对应的基站需要向Cell 1对应的基站请求获取该UE的上下文，而如图2B所示出的，则在该UE与Cell 2的RRC重建立流程中，Cell 2对应的基站不需要向Cell 1对应的基站请求获取该UE的上下文，节省了无线资源。
在一个可能的实施例中，所述至少一个缓存状态报告中的部分或者全部中每个缓存状态报告的发送时机在该缓存状态报告对应的终端执行与所述第 二网络设备的RRC重建立操作的结束时刻之前。
举例来说，所述至少一个终端包括终端甲，终端乙，终端丙，终端丁。所述至少一个缓存状态报告包括与该终端甲对应的缓存状态报告A，该终端乙对应的缓存状态报告B，该终端丙对应的缓存状态报告C，该终端丁对应的缓存状态报告D。若终端甲执行与所述第二网络设备的RRC重建立操作的结束时刻为时刻1，该终端乙执行与所述第二网络设备的RRC重建立操作的结束时刻为时刻1，该终端丙执行与所述第二网络设备的RRC重建立操作的结束时刻为时刻2，该终端丁执行与所述第二网络设备的RRC重建立操作的结束时刻为时刻2，则缓存状态报告A和缓存状态报告B的发送时机在时刻1之前，缓存状态报告C的发送时机在时刻2之前，缓存状态报告D的发送时机在时刻3之前。
需要说明的是，若第一网络设备在终端执行与所述第二网络设备的RRC重建立操作的结束时刻之前，向第二网络设备发送该终端的缓存状态报告(如待传输数据量)，则在该终端在接入第二小区之后，无需再向第二网络设备发送该待传输数据量。
在具体的应用场景中，如图2C所示出的，UE处于目标地理区域中，该目标地理区域的Cell 1切换到Cell 2的流程，从T1时刻之后，T1时刻为Cell1停止服务该目标地理区域的时刻，UE会进入与Cell 1所对应的基站的RLF流程，在该RLF流程完成之后，该UE会进入与Cell 2的RRC重建立流程，在UE完成RLF流程和RRC重建立流程之后，UE和Cell 1对应的基站进行数据传输，Cell 1对应的基站在该UE执行与所述第二网络设备的RRC重建立操作的结束时刻T2之前，将该UE的待传输数据量(该UE在Cell 1停止向所述目标地理区域提供服务的时刻对应的待传输数据量)发送到Cell 2对应的基站，因此，该UE不需要向Cell 2对应的基站上报该UE的待传输数据量，节省了无线资源，减少了UE耗电。
在一个可能的实施例中，所述辅助信息包括所述第三通知信息，所述第二网络设备在所述第一小区切换到所述第二小区之前，接收来自所述第一网络设备的辅助信息之后，所述方法还包括：若获取到不携带标识信息的RRC重建立请求，则所述第二网络设备向第三网络设备获取第一小区的PCI信息，所述PCI信息用于指示所述第一小区的PCI；所述第二网络设备根据所述PCI信息确定所述RRC重建立请求的终端的PCI为所述第一小区的PCI。
即是，第二小区能够通过第三网络设备配置，获知覆盖目标地理区域的上一个小区是第一小区。
示例的，本申请实施例提供的又一种信息传输方法。终端在目标地理区域的第一小区切换到第二小区之前，获取辅助信息。
其中，所述第一小区为所述第一网络设备对应的小区，所述第二小区为第二网络设备对应的小区，所述终端为在所述第一小区中处于连接态或INACTIVE态的终端。
其中，所述辅助信息包括第二通知信息和/或第四通知信息；所述第二通知信息用于指示向所述第二小区发送的RRC重建立请求不携带所述第一小区的标识信息；所述第四通知信息用于指示所述第一小区的停止覆盖所述目标地理区域的时刻和所述第二小区开始覆盖所述目标地理区域的时刻。
可见，本示例中，在第一小区中处于连接态或INACTIVE态的终端在目标地理区域的第一小区切换到第二小区之前，获取辅助信息，实现第二小区为目标地理区域提供服务之后，终端直接基于辅助信息与第二网络设备进行数据交互，因为，终端在所述第一小区切换到所述第二小区之前针对辅助信息的获取以及完成，可以直接使用，减少第二网络设备向终端或者第一网络设备请求辅助信息的流程，节省了无线资源。
其中，所述第二通知信息是所述第一网络设备配置的。
实际应用中，为了保证该UE和Cell 2对应的基站在RRC重建立流程中获取信息一致性。可以通过在目标地理区域的Cell 1切换到Cell 2之前，通过所述第一网络设备向第二网络设备发送第三通知信息(参见方法示例1中针对第三通知信息的描述，此处不再赘述)，或者通过协议规定该Cell 2对应的第二网络设备的第三通知信息。
需要明确的是，实际应用中，第二通知信息和第三通知信息是协同出现的。
若所述第二通知信息是所述第一网络设备配置的，则参考图3A，图3A为本申请实施例提供的另一种信息传输处理方法的流程图，如图3A所示，信息传输处理方法具体包括如下步骤。
S201、第一网络设备在目标地理区域的第一小区切换到第二小区之前，向终端提供辅助信息。
S201、所述终端在所述第一小区切换到所述第二小区之前，接收来自所述第一网络设备的辅助信息。
此种情况下，为了保证UE和Cell 2对应的基站在RRC重建立流程中获取信息一致性。所述第一网络设备也可以提所述第一小区切换到所述第二小区之前，向第二网络设备发送第三通知信息。
在具体的应用场景中，如图3B所示出的，UE处于目标地理区域中，该目标地理区域的Cell 1切换到Cell 2的流程，从T1时刻之后，T1时刻为Cell 1停止服务该目标地理区域的时刻，UE会进入与Cell 1所对应的基站的RLF流程，在该RLF流程完成之后，该UE会进入与Cell 2的RRC重建立流程，在T1之前，若Cell 1对应的基站向该UE发送了第二指示信息，并向Cell 2 对应的基站发送了第三指示信息，在RLF流程中，UE基于该第二指示信息生成不携带Cell 1的标识信息的RRC重建立请求，并向Cell 2对应的基站发送该RRC重建立请求，Cell 2对应的基站接收到RRC重建立请求之后，基于第三指示信息，确定出该UE来自该Cell 1，可通过接收来自第三网络设备的PCI信息，获知覆盖当前地理区域的上一个小区是cell 1。
在一个可能的实施例中，所述辅助信息包括所述第四通知信息，所述终端获取辅助信息之后，所述方法还包括：所述终端在所述第二小区覆盖所述目标地理区域之后，若所述终端完成第一传输块的预设次数的传输，则根据第四通知信息确定所述目标地理区域的所述第一小区的剩余覆盖时长，所述第二传输块为所述第一传输块之后的第一个待传输的传输块；所述终端根据所述剩余覆盖时长判断是否能完成第二传输块的所述预设次数的传输；若能完成第二传输块的所述预设次数的传输，则所述终端获取所述第二传输块的传输方式，所述传输方式包括通过所述第一小区传输，或者，通过所述第二小区传输；所述终端根据所述传输方式传输所述第二传输块。
其中，该预设次数是预先配置的，该预设次数可以是3次，4次，8次，等等，不作具体限定。
在一个可能的实施例中，所述传输方式是所述终端根据所述第二传输块的时延预算剩余量确定的，或者所述第一网络设备通过RRC信令和媒体接入控制控制信元MAC CE信令中的至少一种配置的。
具体的，终端根据所述第二传输块的时延预算剩余量确定的传输方式的实现方式具体可以是：判断所述第二传输块的时延预算是否大于门限；如果时延预算大于门限，就确定传输方式为通过所述第二小区传输所述待传输的传输块；如果时延预算小于门限，就确定所述传输方式为通过所述第一小区传输。
在一个可能的实施例中，若不能完成第二传输块的所述预设次数的传输，则通过所述第二小区传输所述第二传输块。
在具体的应用场景中，如图3C所示出的，UE处于目标地理区域中，T1为Cell 1停止服务该目标地理区域的时刻，T4为Cell 2开始服务该目标地理区域的时刻，则T1至T4之间的时间段为Cell 1为目标区域提供服务以及Cell 2为目标区域提供服务存在重合的时间段，若Cell 1对应的基站在T4之前向该UE发送第四指示信息，若UE在T1之后完成对传输块TB1重复传输N次，则会基于第四指示信息确定该目标地理区域的Cell 1的剩余覆盖时长，以进一步获取针对TB1之后需要传输的TB2进行的传输方式。
