具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
卫星通信系统是一种典型的非地面移动通信系统。如图1所示，卫星通信系统一般可以包括卫星101、地面网关102、地面基站103以及核心网104，其中，卫星101与地面基站103通过地面网关102建立通信连接，地面基站103与核心网104建立通信连接。卫星101可以转发地面基站103的通信信号，从而实现对地面基站103无法覆盖的区域的补充。在这些区域里面UE(英文：User Equipment；中文：用户设备)可以和卫星进行通信，尤其是对于偏远地区、沙漠、高山、海洋等地面基站无法覆盖的区域，卫星能够实现对其有效覆盖。
如图2所示，通常来说，卫星通信系统中的卫星101可以包括低轨道卫星和高轨道卫星，需要指出的是，这里的低轨道卫星和高轨道卫星是相对的概念，换言之，在本申请实施例中，飞行高度相对较低的卫星称为低轨道卫星，而飞行高度相对较高的卫星称为高轨道卫星。
在一种可能的情况下，低轨道卫星和高轨道卫星之间没有通信链路，这意味着高轨道卫星与低轨道卫星之间是相对独立的状态。如图3所示，高轨道卫星g1通过地面网关w1和地面基站d1进行通信，低轨道卫星g2通过地面网关w2和地面基站d2进行通信，在图3中，低轨道卫星和高轨道卫星之间没有通信链路，是相对独立的状态。
在另一种可能的情况下，低轨道卫星和高轨道卫星之间存在通信链路，在这种情况下，典型的系统架构如图4和图5所示。
在图4中，高轨道卫星g1与低轨道卫星g2之间存在地面基站接口，也即是，高轨道卫星g1与低轨道卫星g2通过地面网关与同一地面基站建立通信连接，或者，高轨道卫星与低轨道卫星通过地面网关与存在基站间接口的不同的地面基站建立通信连接，在这种架构中，地面基站可以对高轨道卫星与低轨道卫星进行协调和配置。
在图5中，高轨道卫星g1与低轨道卫星g2存在卫星间接口，高轨道卫星g1和低轨道卫星g2可以通过卫星间接口直接通信，以进行相互协调，需要指出的是，尽管图5中示出高轨道卫星g1不与地面基站通信连接，但是，在实际实现时，这种架构中的高轨道卫星g1也可以通过地面网关与地面基站通信连接。
一般来说，高轨道卫星对应的小区(可以称为高轨道卫星小区)的覆盖范围相对较广，而低轨道卫星对应的小区(可以称为低轨道卫星小区)的覆盖范围相对较小，且，低轨道卫星小区的覆盖范围会随着低轨道卫星的运动而移动。
由于低轨道卫星小区的覆盖范围相对较小，且，低轨道卫星小区的覆盖范围会随着低轨道卫星的运动而移动，因此，低轨道卫星小区难以实现连续覆盖，也即是存在着覆盖盲区，相比之下，高轨道卫星小区的覆盖范围相对较大，且，高轨道卫星一般不存在覆盖盲区。
请参考图6，在t1到t2的时间段内UE处于低轨道卫星小区的覆盖范围内，其可以通过低轨道卫星小区与地面基站进行通信，在t2到t3的时间段内由于当前覆盖UE的低轨道卫星飞离，而新的低轨道卫星并未抵达，因此，在这段时间内UE没有低轨道卫星覆盖，t3到t4时间内新的低轨道卫星抵达，使得UE重新进入低轨道卫星小区的覆盖范围内。如图6所示，由于存在覆盖盲区，因此，UE的通信是不连续的。
请参考图7，在图7中，t1至t4的时间段内，高轨道卫星小区一直对UE进行覆盖，其一直可以为UE提供通信服务，因此，高轨道卫星小区的覆盖能力相较于低轨道卫星小区而言较强，其一般不存在覆盖盲区。
除此以外，由于高轨道卫星与地面的距离较远，受到发射功率的限制，UE一般只能在高轨道卫星小区中进行下行信号的接收，而无法进行上行通信，低轨道卫星与地面的距离较近，UE一般可以在低轨道卫星小区内进行上下行双向通信。
由于卫星通信系统具有和一般的无线通信系统不同的架构以及特性，因此，需要针对卫星通信系统进行单独地研究，当前，如何提升卫星通信系统的性能已经成为重点研究方向。
有鉴于此，本申请实施例提供了一种卫星通信方法，可以应用于UE中，请参考图8，该卫星通信 方法包括以下步骤：
步骤801、UE接收高轨道卫星发送的下行信号。
其中，该下行信号携带低轨道卫星小区的系统信息和低轨道卫星小区对应的低轨道卫星的星历信息。
在本申请的可选实施例中，该下行信号可以为系统广播信息，该系统信息可以包括低轨道卫星小区的工作频率和/或带宽，该星历信息可以包括低轨道卫星的运行速度、轨道位置等用于跟踪、预测、计算以及描绘低轨道卫星运行状态的信息。
步骤802、UE基于该系统信息和该星历信息接入低轨道卫星小区。
如上文所述，由于低轨道卫星小区的覆盖范围相对较小，且，低轨道卫星小区的覆盖范围会随着低轨道卫星的运动而移动，因此，低轨道卫星小区难以实现连续覆盖，存在着覆盖盲区。现有技术中，UE在失去低轨道卫星小区的覆盖之后，就会在低轨道卫星小区的所有可能的带宽以及工作频率上搜索低轨道卫星小区，而在低轨道卫星的覆盖盲区中，这种搜索是徒劳的，直至UE重新进入低轨道卫星小区的覆盖范围内，UE才可以通过搜索接入低轨道卫星小区中。
上述现有技术的方式需要UE进行长时间的搜网，而且，UE在部分时段内的搜网是徒劳的，这导致UE的搜网效率较低，功耗较大。
而在本申请提供的实施例中，UE可以优先在高轨道卫星小区的所有可能的带宽以及工作频率上搜索高轨道卫星小区，以获取高轨道卫星小区的下行信号，其中，该下行信号中携带低轨道卫星小区的系统信息和低轨道卫星小区对应的低轨道卫星的星历信息，这样，UE就可以基于该系统信息和该星历信息进行有针对性地搜网，因此，可以极大地减小UE搜网的时间，提升UE搜网的效率，降低UE的功耗。
请参考图9，在图8所示实施方式的基础上，其示出了UE基于系统信息和星历信息接入低轨道卫星小区的过程的流程图，如图9所示，该过程包括以下步骤：
步骤901、UE基于星历信息确定低轨道卫星小区的到达时间。
其中，该到达时间用于指示低轨道卫星小区的覆盖范围移动至目标区域的时刻，该目标区域为UE所处的区域。
步骤902、UE根据到达时间确定小区接入时间，并在小区接入时间基于系统信息接入低轨道卫星小区。
换言之，在本申请实施例中，UE可以基于星历信息确定低轨道卫星小区开始覆盖UE的时间，也即是上文中的到达时间，UE可以基于该到达时间确定小区接入时间，其中，该小区接入时间可以为该到达时间，也可以为与该到达时间相差较小的一个时间，UE在该小区接入时间进行搜网并接入低轨道卫星小区可以避免UE在低轨道卫星的覆盖盲区中进行徒劳地搜网，因此，可以极大地减小UE搜网的时间，提升UE搜网的效率，降低UE的功耗。
除此以外，UE可以基于系统信息确定低轨道卫星小区的工作频率和/或带宽，这样，UE在进行搜网时就不需要在低轨道卫星小区的所有可能的带宽以及工作频率上进行搜索，而是可以根据系统信息在特定的带宽和/或工作频率上搜网，因此，也可以起到减小UE搜网的时间，提升UE搜网的效率，降低UE的功耗的作用。
请参考图10，本申请实施例还提供了另一种卫星通信方法，可以应用于卫星通信系统的高轨道卫星中，请参考图10，该卫星通信方法包括以下步骤：
步骤1001、高轨道卫星发送下行信号。
其中，该下行信号携带低轨道卫星小区的系统信息和低轨道卫星小区对应的低轨道卫星的星历信息，该系统信息和该星历信息用于供UE基于系统信息和星历信息接入低轨道卫星小区。
与上文所述同理地，在本申请的可选实施例中，该下行信号可以为系统广播信息，该系统信息可以包括低轨道卫星小区的工作频率和/或带宽。
请参考图11，本申请实施例还提供了另一种卫星通信方法，可以应用于卫星通信系统中，请参考图11，该卫星通信方法包括以下步骤：
步骤1101、高轨道卫星发送下行信号。
其中，该下行信号携带低轨道卫星小区的系统信息和低轨道卫星小区对应的低轨道卫星的星历信息。
步骤1102、UE接收高轨道卫星发送的下行信号。
步骤1103、UE基于星历信息确定低轨道卫星小区的到达时间。
步骤1104、UE根据到达时间确定小区接入时间，并在小区接入时间基于系统信息接入低轨道卫星小区。
需要指出的是，图8至图11对应的卫星通信方法，可以应用于低轨道卫星和高轨道卫星之间没有通信链路，以及低轨道卫星和高轨道卫星之间存在通信链路的架构中。
请参考图12，本申请实施例还提供了另一种卫星通信方法，可以应用于UE中，如图11所示，该卫星通信方法包括以下步骤：
步骤1201、UE与低轨道卫星小区和高轨道卫星小区建立双连接。
其中，高轨道卫星小区对应的高轨道卫星用于向UE转发地面基站的下行数据，低轨道卫星小区对应的低轨道卫星用于接收以及向地面基站转发UE发送的上行数据，并用于向UE转发地面基站的下行数据。
换言之，请参考图13，在本申请实施例中，UE可以通过低轨道卫星小区与地面基站进行上下行通信，并可以通过高轨道卫星小区与地面基站进行下行通信。
如上文所述，低轨道卫星小区的覆盖范围较小，且，存在着覆盖盲区，而高轨道卫星小区的覆盖范围较大，且，一般不存在覆盖盲区，但是，由于受到发射功率的限制，UE一般无法通过高轨道卫星小区与地面基站进行上行通信。
基于以上情况，在本申请实施例提供的卫星通信方法中，UE可以与低轨道卫星小区和高轨道卫星小区建立双连接，这样，在低轨道卫星的覆盖盲区中，就可以由高轨道卫星小区实现对UE的信号覆盖，使得在低轨道卫星的覆盖盲区中，UE可以通过高轨道卫星小区接收地面基站的下行数据，这样，高轨道卫星小区就可以作为低轨道卫星小区的覆盖补充，从而实现对UE的连续信号覆盖，提升卫星通信系统的性能。
同时，在低轨道卫星小区的覆盖范围内，可以由高轨道卫星和低轨道卫星共同向UE发送地面基站的下行数据，因此，可以实现对低轨道卫星的负载分流，实现通信容量的扩充，实现更高的数据吞吐量。
请参考图14，其示出了一种示例性地UE与低轨道卫星小区和高轨道卫星小区建立双连接的技术过程，该技术过程包括以下步骤：
步骤1401、UE接入低轨道卫星小区，并通过低轨道卫星小区向地面基站上报UE的连接支持能力，以供地面基站根据连接支持能力为UE配置高轨道卫星小区。
在本申请的可选实施例中，UE可以基于上文中图8至图11任一对应的卫星通信方法接入低轨道卫星小区中。
在本申请的可选实施例中，该连接支持能力可以包括以下内容中的至少一种：UE支持接入的小区的工作频率；UE支持接入的小区的工作频段；UE支持的双连接频段组合。
与上文所述的连接支持能力对应的，地面基站为UE配置的高轨道卫星小区需要满足以下内容中的至少一种：高轨道卫星小区的工作频率和UE支持接入的小区的工作频率相匹配；高轨道卫星小区的工作频段和UE支持接入的小区的工作频段相匹配；高轨道卫星小区的工作频段以及UE接入的低轨道卫星小区的工作频段与UE支持的双连接频段组合相匹配。
步骤1402、UE基于地面基站的配置与高轨道卫星小区建立下行连接。
需要指出的是，如上文所述，低轨道卫星小区具有覆盖盲区，在现有技术中，进入覆盖盲区之后，UE与低轨道卫星小区的通信链路将会断开，在由覆盖盲区重新进入低轨道卫星小区的覆盖范围之后，UE需要重新接入低轨道卫星小区，如果UE频繁地执行接入低轨道卫星小区的过程，并且，在每次接入低轨道卫星小区之后，都执行向地面基站上报UE的连接支持能力的过程，地面基站都执行为UE配置高轨道卫星小区的过程，会导致整个过程非常繁琐，效率较低。
而考虑到虽然与UE通信连接的低轨道卫星会发生变化，但对于UE而言，与其保持连接的地面基站是不变的。因此，在本申请实施例中，当UE进入覆盖盲区之后，地面基站并不在信令层面上释放UE与低轨道卫星小区和高轨道卫星小区的连接，而是保留其连接信息，在UE重新进入低轨道卫星小区的覆盖范围之后，地面基站将该连接信息发送至新的低轨道卫星中，以重新激活UE与低轨道卫星小区的连接，这样，在信令层面上，UE始终保持与低轨道卫星和高轨道卫星小区的连接，因此，UE不需要频繁地执行接入低轨道卫星小区的过程，也不需要多次执行向地面基站上报UE的连接支持能力的过程，地面基站也不需要多次执行为UE配置高轨道小区的过程，故而可以简化流程，提升通信效率。
请参考图15，在上文所述的基础上，图15示出了一种示例性卫星通信方法的流程图，如图15所 示，该卫星通信方法包括以下步骤：
步骤1501、UE通过高轨道卫星小区或者低轨道卫星小区接收地面基站下发的覆盖时间。
其中，该覆盖时间用于指示低轨道卫星小区的通信信号覆盖UE的时间段。
在本申请的可选实施例中，地面基站可以通过RRC高层信令向UE下发该覆盖时间，也可以通过下行控制信息向UE下发该覆盖时间，本申请实施例对此不作具体限定。
步骤1502、UE根据覆盖时间，通过高轨道卫星小区和低轨道卫星小区中的至少一个与地面基站进行通信。
在本申请实施例中，虽然在UE进入覆盖盲区之后，地面基站并不在信令层面上释放UE与低轨道卫星小区和高轨道卫星小区的连接，但是，实际上UE无法通过低轨道卫星小区与地面基站进行通信。除此以外，不同的UE的能力不同，有些UE在同一时间只能保持一个通信连接，对于这部分UE而言，其需要在位于低轨道卫星小区的覆盖范围内时，选择与低轨道卫星小区和高轨道卫星小区中的一个保持通信连接，以与地面基站进行通信。
考虑到以上情况，地面基站可以向UE下发低轨道卫星小区的通信信号覆盖UE的时间段，也即是覆盖时间，UE可以根据覆盖时间，通过高轨道卫星小区和低轨道卫星小区中的至少一个与地面基站进行通信。
其中，在本申请的可选实施例中，在覆盖时间内，UE可以通过低轨道卫星小区与地面基站进行上下行通信，并通过高轨道卫星小区与地面基站进行下行通信(UE具有同时保持两个通信连接的能力)；或者，UE暂停通过高轨道卫星小区与地面基站进行下行通信，并通过低轨道卫星小区与地面基站进行上下行通信(UE只有在同一时间仅保持一个通信连接的能力)。
在覆盖时间之外，UE通过高轨道卫星小区与地面基站进行下行通信，并暂停通过低轨道卫星小区与地面基站进行上下行通信。
请参考图16，其示出了另一种卫星通信方法的流程图，应用于卫星通信系统的地面基站中，如图16所示，该卫星通信方法包括以下步骤：
步骤1601、地面基站接收UE在接入低轨道卫星小区后通过低轨道卫星小区上报的UE的连接支持能力。
在本申请的可选实施例中，该连接支持能力包括以下内容中的至少一种：UE支持接入的小区的工作频率；UE支持接入的小区的工作频段；UE支持的双连接频段组合。
步骤1602、地面基站根据该连接支持能力为UE配置高轨道卫星小区，以供UE与高轨道卫星小区建立下行连接。
其中，高轨道卫星小区对应的高轨道卫星用于向UE转发地面基站的下行数据，低轨道卫星小区对应的低轨道卫星用于接收以及向地面基站转发UE发送的上行数据，并用于向UE转发地面基站的下行数据。
如上文所述，在UE于高轨道卫星小区和低轨道卫星小区建立双连接之后，当UE进入覆盖盲区之后，地面基站并不在信令层面上释放UE与低轨道卫星小区和高轨道卫星小区的连接，而是保留其连接信息，在UE重新进入低轨道卫星小区的覆盖范围之后，地面基站将该连接信息发送至新的低轨道卫星中，以重新激活UE与低轨道卫星小区的连接，这样，在信令层面上，UE始终保持与低轨道卫星和高轨道卫星小区的连接。
请参考图17，在图16所示的方法的基础上，本申请还提供了另一种卫星通信方法，该卫星通信方法包括以下步骤：
步骤1701、地面基站通过低轨道卫星小区或者高轨道卫星小区向UE下发覆盖时间。
其中，该覆盖时间用于指示低轨道卫星小区的通信信号覆盖UE的时间段，以供UE根据覆盖时间，通过高轨道卫星小区和低轨道卫星小区中的至少一个与地面基站进行通信。
需要指出的是，图12至图17对应的卫星通信方法，可以应用于低轨道卫星和高轨道卫星之间存在通信链路的架构中。
如上文所述，在低轨道卫星和高轨道卫星之间存在通信链路的架构中，高轨道卫星与低轨道卫星可以基于地面基站接口通信连接，在这种情况下，可以由地面基站实现下行数据的负载分流，也即是，地面基站可以将下行数据发送至高轨道卫星和低轨道卫星中的至少一个，以由高轨道卫星和/或低轨道卫星将下行数据转发至UE。
此外，在低轨道卫星和高轨道卫星之间存在通信链路的架构中，高轨道卫星与低轨道卫星还可以基于卫星间接口通信连接，在这种情况下，地面基站可以将下行数据发送至低轨道卫星，以由低轨道卫星 基于卫星间接口将下行数据转发至高轨道卫星，而后，再由高轨道卫星和低轨道卫星共同将下行数据转发至UE。
请参考图18，其示出了本申请实施例提供的另一种卫星通信方法，应用于卫星通信系统中的低轨道卫星中，如图18所示，该卫星通信方法包括以下步骤：
步骤1801、低轨道卫星接收并向地面基站转发UE上报的UE的连接支持能力，以供地面基站根据连接支持能力为UE配置高轨道卫星小区。
其中，高轨道卫星小区对应的高轨道卫星用于向UE转发地面基站的下行数据，低轨道卫星用于接收以及向地面基站转发UE发送的上行数据，并用于向UE转发地面基站的下行数据。
如上文所述，在高轨道卫星与低轨道卫星基于卫星间接口通信连接的情况下，低轨道卫星可以接收地面基站发送的下行数据，并基于卫星间接口将下行数据转发至高轨道卫星，而后，再由高轨道卫星和低轨道卫星共同将下行数据转发至UE。
请参考图19，其示出了在图18所示的卫星通信方法的基础上，本申请实施例还提供了另一种卫星通信方法，如图19所示，该卫星通信方法包括以下步骤：
