其中，非地面移动通信子网络和地面移动通信子网络采用相同或者统一的无线接入技术。
上述跨层载波聚合模式也可以称为层间载波聚合模式。
可选地，在步骤103中设置成跨层载波聚合模式中将覆盖范围最大的子网络的信号作为主载波。
也就是，网络控制单元可以依据终端当前工作对应的子网络是单层覆盖还是多层覆盖来决定是否进行层间载波聚合。如果只有单层覆盖，则该覆盖对应的子网络设置成独立工作模式或者层内载波聚合模式。如果有多层覆盖，则将各层覆盖对应的子网络设置成层间载波聚合模式。

可以理解的是，在本公开实施例中对于网络控制单元通知的第一信息和执行的顺序不做具体限定。

也就是，网络控制单元可以对正在通信的各层子网络的状态进行检测，出现异常情况时，网络控制单元可以提前发送协调信息，关闭该层子网络的信号发送或禁止用户接入该层子网络，通知用户切换到其他层子网络。
可以理解的是，在本公开实施例中对于网络控制单元通知的第二信息的方式和执行的顺序不做具体限定。
在一些实施方式中，图1所示的方法还可以包括：动态配置或静态配置所述非地面移动通信子网络和/或所述地面移动通信子网络的工作带宽。可以理解的是，在本公开实施例中对于网络控制单元配置各层子网络的工作带宽的方式和执行的顺序不做具体限定。
比如，针对静态配置，各层子网络只工作在分配的工作带宽；针对动态配置，各层子网络均能工作在整个系统带宽，但实际占用的带宽可以与系统的容量和/或速率需求等因素有关，所有子网络的实际占用带宽总和小于等于整个系统带宽；可选地，不同的子网络可以配置为不同的载波或者不同的部分带宽(Bandwidth Part，BWP)。
可选地，对同一地区提供小区覆盖的非地面移动通信子网络和地面移动通信子网络的无线信号所使用的频段是通过对通信系统的带宽划分获得的。
比如，非地面移动通信子网络使用系统带宽中较低的频段。
可选地，带宽划分可以是预先分配好的静态划分，即非地面移动通信子网络的无线信号和地面移动通信子网络的无线信号分别工作在固定的带宽。
可选地，带宽划分可以是随时变化的动态划分，即非地面移动通信子网络的无线信号和地面移动通信子网络的无线信号的工作带宽可以发生变化。示例性地，网络控制单元依据容量和/或数据传输的速率需求来计算非地面移动通信子网络和地面移动通信子网络各自需要的工作带宽；又示例性地，网络控制单元动态调整非地面移动通信子网络和地面移动通信子网络的工作带宽。
可以理解的是，所有子网络的实际占用带宽总和小于等于整个系统带宽。
在本公开实施例中，非地面移动通信子网络和地面移动通信子网络采用相同或者统一的无线接入技术，比如，4G、5G、6G等无线接入技术，也就是能够让非地面移动通信和地面移动通信形成的异构立体覆盖被当作一个统一的网络系统来进行通信，避免非地面通信系统和地面移动通信系统的相关技术中的“双系统”工作方式，带来了无线资源、系统建设与设备实现等多个方面的浪费的问题。

下面结合实施例一和实施例二介绍本公开的实施方式。
实施例一：GEO星座+LEO星座+地面蜂窝基站的3层异构立体网络。
所述非地面移动通信子网络包括：GEO星座、LEO星座和与所述GEO星座、LEO星座通信连接的地面信关站；
所述地面移动通信子网络包括：地面基站；
所述网络控制单元分别与所述地面信关站、地面基站通信连接。
如图4所示，假设某个通信系统由GEO星座、LEO星座、地面信关站、地面蜂窝基站、网络控制单元和终端组成，形成了3层异构立体分层覆盖。
从终端角度来看，由GEO星座和地面信关站组成的子网络形成了覆盖区域最大的第1层覆盖，由LEO星座和地面信关站组成的子网络形成了覆盖区域次之的第2层覆盖，地面蜂窝基站形成了区域最小的第3层覆盖。即，针对终端所在的地面蜂窝基站覆盖的区域，还有着固定不动的GEO卫星和快速运动的LEO卫星的覆盖。
在网络控制单元的统一协调处理下，各层覆盖所形成的子网络的占用带 宽有着静态或者动态的划分方式。
假设系统的工作带宽为B MHz，在静态方式下，将总带宽B MHz固定地划分为不重叠的3段，假设记为B 1，B 2，B 3，则满足B 1+B 2+B 3≤B。3段带宽分别分配给三层覆盖的子网络，使得三层覆盖的子网络只按照给定的带宽去进行设计，如GEO星座子网络只工作在带宽B 1，LEO星座子网络只工作在带宽B 2，地面基站子网络只工作在带宽B 3。
假设系统的工作带宽为B MHz，在动态方式下，三层覆盖的子网络均按照整个工作带宽B去进行设计，但实际工作的带宽是动态变化的，与特定区域、特定时间的系统容量和速率需求等因素有关。不失一般性，假设终端处于第i个区域，其对应的3层覆盖的子网络的工作带宽分别为B 1,i，B 2,i，B 3,i，则有B 1,i+B 2,i+B 3,i≤B；假设终端处于第j个区域，其对应的3层覆盖的子网络的工作带宽分别为B 1,j，B 2,j，B 3,j，则有B 1,j+B 2,j+B 3,j≤B；因为第i个区域和第j个区域的系统容量和速率需求不同，存在B 1,i≠B 1,j，B 2,i≠B 2,j，B 3,i≠B 3,j。
在网络控制单元的统一协调处理下，各层覆盖的子网络通过载波聚合的方式来为终端提供服务。
可以理解的是，可以将GEO卫星形成的第1层覆盖作为主载波，用于终端的接入、同步、控制和低速率数据传输；可以将LEO卫星形成的第2层覆盖和地面基站形成的第3层覆盖均作为辅载波，用于终端的高速率数据传输。
终端与网络通信过程中，网络会实时监测自身工作状态的变化，终端也会实时地将自身信息通知给网络，便于网络对当前工作状态做更好地判断和处理。例如，假如网络检测到终端连接的多层星座子网络有1层星座子网络的卫星不可用时，网络通知终端断开与不可用卫星的连接，转入其他星座子网络和/或地面子网络进行通信。
需要说明的是，图4中的终端，可以直接与GEO星座通信连接，地面信关站GW2可以与一个或多个第2个LEO卫星星座中的卫星通信连接。
实施例二：LEO星座+地面蜂窝基站的3层异构立体网络。
如图5所示，假设某个通信系统由LEO星座、地面信关站、地面蜂窝基站、网络控制单元和终端组成，形成了3层异构立体分层覆盖。
所述非地面移动通信子网络包括：LEO星座和与所述LEO星座通信连接 的地面信关站；
所述地面移动通信子网络包括：地面基站；
所述网络控制单元分别与所述地面信关站、所述地面基站通信连接。
从终端角度来看，由LEO星座和地面信关站组成的子网络形成了控制波束和点波束的2层覆盖，其中控制波束为覆盖区域最大的第1层覆盖，点波束为覆盖区域次之的第2层覆盖，地面蜂窝基站形成了区域最小的第3层覆盖。即，针对终端所在的地面蜂窝基站覆盖的区域，还有着快速运动的LEO卫星的控制波束覆盖和点波束覆盖。
在网络控制单元的统一协调处理下，各层覆盖所形成的子网络的占用带宽有着静态或者动态的划分方式。
假设系统的工作带宽为B MHz，在静态方式下，将总带宽B MHz固定地划分为不重叠的3段，假设记为B 1，B 2，B 3，则满足B 1+B 2+B 3≤B。3段带宽分别分配给三层覆盖的子网络，使得三层覆盖的子网络只按照给定的带宽去进行设计，如LEO星座的控制波束子网络只工作在带宽B 1，LEO星座的点波束子网络只工作在带宽B 2，地面基站子网络只工作在带宽B 3。
假设系统的工作带宽为B MHz，在动态方式下，三层覆盖的子网络均按照整个工作带宽B去进行设计，但实际工作的带宽是动态变化的，与特定区域、特定时间的系统容量和速率需求等因素有关。不失一般性，假设终端处于第i个区域，其对应的3层覆盖的子网络的工作带宽分别为B 1,i，B 2,i，B 3,i，则有B 1,i+B 2,i+B 3,i≤B；假设终端处于第j个区域，其对应的3层覆盖的子网络的工作带宽分别为B 1,j，B 2,j，B 3,j，则有B 1,j+B 2,j+B 3,j≤B；因为第i个区域和第j个区域的系统容量和速率需求不同，存在B 1,i≠B 1,j，B 2,i≠B 2,j，B 3,i≠B 3,j。
在网络控制单元的统一协调处理下，各层覆盖的子网络通过载波聚合的方式来为终端提供服务。
可以理解的是，可以将LEO卫星的控制波束形成的第1层覆盖作为主载波，用于终端的接入、同步、控制和低速率数据传输；可以将LEO卫星的点波束形成的第2层覆盖和地面基站形成的第3层覆盖均作为辅载波，用于终端的高速率数据传输。
终端与网络通信过程中，网络会实时监测自身工作状态的变化，终端也 会实时地将自身信息通知给网络，便于网络对当前工作状态做更好地判断和处理。例如，假如网络检测到终端连接的地面子网络不可用时，网络通知终端断开与地面子网络的连接，转入与各卫星子网络进行通信。
