具体实施方式
下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员基于本公开所获得的所有其他实施例,都属于本公开保护的范围。
由于目前所分配单独ATG专用频率大多数仅仅分配了较小的带宽,且目前很难单独划出一段宽带频率来给ATG系统单独使用,而用户对于航空移动业务带宽需求则不断提升,因此,迫切需要提供一种满足用户对于航空移动业务带宽需求的方案。
本公开实施例公开了航空移动通信系统、方法、装置、电子设备及介质,以下分别进行说明。
本公开实施例提供了航空移动通信系统,参见图1,图1为本公开实施例的航空移动通信系统的一种示意图,包括:
ATG终端110和多个ATG基站120;ATG终端的信号频率与IMT基站的信号频率至少部分相同;
ATG基站,用于在自身通信服务的目标ATG终端需要切换ATG基站时,生成针对目标ATG终端的测量指令,并将测量指令发送给目标ATG终端;ATG终端110可以包括目标ATG终端;
目标ATG终端,用于在接收到测量指令之后,基于测量指令获取通 信范围内多个ATG基站的下行信号,得到各下行信号的测量结果,并将各下行信号的测量结果发送至为自身提供通信服务的ATG基站;
ATG基站,还用于接收各下行信号的测量结果,以及获取目标ATG终端到每一个ATG基站的上行信号所覆盖区域中IMT基站的数量;基于各下行信号的测量结果、以及IMT基站的数量确定出目标ATG基站,并向目标ATG终端发送切换基站指令,向目标ATG基站发送为目标ATG终端提供服务的指令;
目标ATG终端,用于在接收到切换基站指令后,发送上行信号至目标ATG基站;
目标ATG基站,用于在接收到为目标ATG终端提供服务指令之后,为目标ATG终端提供通信服务。
本公开中,ATG终端的信号频率与IMT基站的信号频率至少部分相同,也就是说,航空移动通信中的ATG终端与地面IMT基站可以采用相同频率,以此可以拓宽ATG终端可以使用的频率带宽,从而满足用户对航空移动业务带宽的需求。而且,当目标ATG终端需要切换ATG基站,当前为目标ATG终端提供通信服务的ATG基站基于其他基站至目标ATG终端的下行信号的测量结果、目标ATG终端到其他每一个ATG基站的上行信号所覆盖区域中IMT基站的数量确定出目标ATG基站,从而在目标ATG终端需要切换ATG基站时,可以基于其他基站至目标ATG终端的下行信号的信号质量、目标ATG终端到其他每一个ATG基站的上行信号所覆盖区域中IMT基站的数量从其他ATG基站中确定出合适的ATG基站。
当ATG终端与ATG基站进行通信的频率与IMT基站区域的频率相同时,即ATG系统(ATG终端与ATG基站进行通信的系统)与IMT系统(IMT基站提供通信服务的系统)进行同频组网,如图2所示,ATG终端从飞机上对着地面ATG基站发射上行信号时,将会对地面IMT基站的上行产生同频干扰信号,并且由于ATG终端对地发射信号时覆盖地域范围非常大,地面大量IMT基站都会收到ATG终端干扰信号,这对IMT系统性能影响巨大。同时,地面IMT基站由于天线上旁瓣向上发射下行信号,每个IMT基站天线的上旁瓣均不一致,且对空发射链路损耗较 小,大量地面IMT基站对空发射的下行同频信号将对ATG基站的下行链路产生干扰,甚至在部分空域形成大量IMT基站下行信号叠加的集总强干扰区域。
而且,如图3a所示,为了实现飞行过程中持续为航空器上用户提供航空移动ATG业务,ATG终端在不同的ATG基站间切换上下行链路,并保持ATG通信的平稳性,因此当ATG基站为ATG终端提供通信服务时,ATG基站需要确定目标ATG终端在何种条件下需要切换ATG基站,具体的,可以基于ATG基站与目标ATG终端之间的通信信号质量和/或ATG终端到该ATG基站的上行信号对其覆盖区域中的IMT基站是否存在上行干扰及干扰程度来确定。例如,当ATG基站与目标ATG终端之间的通信信号质量低于预设阈值时,为了保持ATG通信的平稳性,可以确定ATG终端需要切换ATG基站,或者,当ATG终端到该ATG基站的上行信号对上行信号所覆盖区域中的IMT基站存在上行干扰,且干扰程度超过预设阈值,则确定ATG终端需要切换ATG基站。
在确定目标ATG终端需要切换ATG基站时,生成针对目标ATG终端的测量指令,并将测量指令发送给目标ATG终端,该测量指令用于指示目标ATG终端测量其他ATG基站的下行信号,具体的,该测量指令用于指示目标ATG终端测量其通信范围内的所有ATG基站的下行信号,得到各下行信号的测量结果,其中,各下行信号的测量结果表征各个下行信号的质量测量结果,其中可以包括各个下行信号的信噪比和/或信号强度等表征信号质量的信息,然后下行信号的质量测量结果发送给ATG基站,由ATG基站选择目标ATG基站。
进一步的,该测量指令用于指示目标ATG终端测量为目标ATG终端提供通信服务的ATG基站邻近的ATG基站。例如,目前ATG终端与ATG基站1进行通信,ATG基站1本身存储了邻近ATG基站的信息,假如ATG基站1邻近的基站为ATG基站2,ATG基站3,ATG基站4,则ATG终端可以仅测量ATG基站2,ATG基站3,ATG基站4的下行信号,然后将获取到的ATG基站的下行信号的质量测量结果发送给ATG基站,由ATG基站选择目标ATG基站。
ATG基站接收各下行信号的测量结果后,并获取目标ATG终端到每 一个ATG基站的上行信号所覆盖区域中IMT基站的数量。其中,ATG基站可以存储周边的各个IMT基站的具体信息,基于预先存储的各个IMT基站的位置信息来确定每一个ATG基站的上行信号所覆盖区域中IMT基站的数量。基于各下行信号的测量结果、以及IMT基站的数量确定出目标ATG基站,并向目标ATG终端发送切换基站指令,向目标ATG基站发送为目标ATG终端提供服务指令,以使目标ATG终端在接收到基站指令后,发送上行信号至目标ATG基站,目标ATG基站,在接收到为目标ATG终端提供服务指令之后,为目标ATG终端提供通信服务。
在一种可能的实施例中,ATG基站可用于:
接收各下行信号的测量结果后,确定各下行信号的信号质量;
当不存在预设数量个ATG基站的下行信号的信号质量达到预设信号质量阈值时,将对应的下行信号的信号质量最好的ATG基站作为目标ATG基站;
当存在预设数量个ATG基站的下行信号的信号质量达到预设信号质量阈值时,针对每一个通信范围内ATG基站,获取目标ATG终端到该ATG基站的上行信号所覆盖区域中IMT基站的数量;将数量最小的ATG基站作为目标ATG基站。
ATG基站接收到各个下行信号的测量结果之后,可以基于信号的信噪比和/或信号的信号强度等任一表征信号质量的参数来确定各下行信号的信号质量,如果当不存在预设数量个下行信号的信号质量达到预设信号质量阈值时,直接选择下行信号质量最好的ATG基站作为目标ATG基站,当存在预设数量个ATG基站的下行信号的信号质量达到预设信号质量阈值时,则优先选择ATG终端到该邻近ATG基站上行信号所覆盖IMT网络基站数量较少的ATG基站作为目标ATG基站,预设数量可以基于实际情况进行设定,例如设定为1,在此不作限定。
如图3所示,为了实现飞行过程中持续为航空器上用户提供航空移动ATG业务,ATG终端在不同的ATG基站间切换上下行链路,并保持ATG通信的平稳性,当ATG终端进行切换时,如果切换目标ATG基站 只有1个,则只要目标ATG基站信号质量达到要求,即可将ATG上下行链路切换到该目标ATG基站,但当ATG终端进行切换时,存在多个信号质量相当的目标ATG基站时,优先选择ATG终端到该邻近ATG基站上行信号所覆盖IMT网络基站数量较少的ATG基站作为目标ATG基站,从而降低当ATG基站与ATG终端进行通信的频率与IMT基站对应的网络频率相同时,ATG终端到该ATG基站的上行信号干扰IMT基站对应的网络的可能性。
在一种可能的实施例中,ATG基站可用于:
在为目标ATG终端提供通信服务时,若接收到指定IMT基站发送的预设信号时,生成测量指令;其中,指定IMT基站为目标ATG终端到该ATG基站的上行信号所覆盖区域中的IMT基站;预设信号表征目标ATG终端到该ATG基站的上行信号对指定IMT基站存在上行干扰,且干扰超过预设干扰阈值。
IMT基站在检测到自身受到上行干扰时,且受到的上行干扰超过预设干扰阈值时,IMT基站向周边所有相邻的ATG基站发送预设信号,以向周边所有相邻的ATG基站告知本身受到了上行干扰。其中,预设信号可以为任意表征ATG终端到该ATG基站的上行信号对其存在上行干扰的指示信号,例如,可以为干扰信号本身,或者ATG基站与IMT约定好的指示信号,如信号“1”,表征受到上行干扰且受到的上行干扰超过预设干扰阈值。
进一步的,ATG基站在为目标ATG终端提供通信服务时,可以与该目标ATG终端到该ATG基站的上行信号所覆盖区域中的IMT基站协议何种信号表征对IMT基站造成了上行干扰,比如,当IMT基站向ATG基站发送信号“1”时,则表征目标ATG终端到该ATG基站的上行信号对其造成上行干扰,且受到的上行干扰超过预设干扰阈值。
各个ATG基站接收到IMT基站发送的预设信号之后,可以基于IMT基站位置信息及自身服务的ATG终端位置分析是否是自身服务的ATG终端的其自身的上行信号对该IMT基站产生的干扰,ATG基站确定IMT基站的位置信息的方式为:各ATG基站内部可以存储其邻近基站的属性信 息,该属性信息包括IMT基站的标识信息,以及IMT基站的位置信息,IMT基站给各个ATG基站发送的预设信号包括其本身的标识信息,ATG基站接收到预设信号之后,可以基于IMT基站的标识信息确定其对应的位置信息。然后基于自身服务的ATG终端的位置信息,确定自身服务的ATG终端到该ATG基站的上行信号所覆盖区域,然后判断IMT基站的位置是否在自身服务的ATG终端到该ATG基站的上行信号所覆盖区域中,若在,则确定是自身服务的ATG终端的其自身的上行信号对该IMT基站产生的干扰。
若ATG基站确定是自身服务的ATG终端的其自身的上行信号对该IMT基站产生的干扰,则生成测量指令,以使目标ATG终端在接收到上述测量指令之后,基于上述测量指令获取通信范围内多个ATG基站的下行信号,当前为目标ATG终端提供通信服务的ATG基站基于其他基站至目标ATG终端的下行信号的信号质量、目标ATG终端到其他每一个ATG基站的上行信号所覆盖区域中IMT基站的数量确定出目标ATG基站,从而在目标ATG终端需要切换ATG基站时,可以基于其他基站至目标ATG终端的下行信号的信号质量、目标ATG终端到其他每一个ATG基站的上行信号所覆盖区域中IMT基站的数量从其他ATG基站中确定出合适的ATG基站,以避免对地面的IMT基站所对应的网络区域造成上行干扰。
示例性的,ATG终端的天线采用多面阵形式进行部署。
为了实现ATG终端与地面不同位置的ATG基站间通信,飞机在航路上飞行时需在不同的ATG基站间切换上下行链路。ATG终端天线可以采用全向天线或多面阵天线的设计方案,因为全向天线将会同时接收来自各个方向地面IMT基站干扰,且会干扰更大范围的地面IMT网络,因此ATG终端可以采用多面阵天线的部署方案,这样当确定了ATG基站之后,可以采用一面天线与ATG基站进行通信,以此不必接收来自所有方向地面MIT基站发出的信号,同时也不会对所有方向的地面IMT基站造成干扰,以此降低当ATG基站与ATG终端进行通信的频率与IMT基站对应的网络频率相同时,ATG终端到该ATG基站的上行信号干扰IMT基站对应的网络的可能性。
在一种可能的实施例中,ATG终端可以包括多个ATG终端天线,ATG基站还可用于:
在为目标ATG终端提供通信服务时,针对每一个通信范围内ATG基站,获取该ATG基站对应的ATG终端天线的发射波束的宽度;
根据ATG终端天线的发射波束的宽度计算目标ATG终端到该ATG基站的上行信号所覆盖区域;
计算覆盖区域中IMT基站的数量。
ATG终端可以包括有多个ATG终端天线,且ATG终端天线可以采用多面阵的方式进行排布,以此实现对地面各个角度信号的接收和发射,如,ATG终端采用一个五面阵天线,除了前后左右各有一面天线之外,对地还有一面天线。在确定了为其提供通信ATG基站之后,ATG终端可以采用一面天线与ATG基站进行通信,如图3b所示,ATG终端天线2发出的ATG上行信号与ATG基站2进行通信,ATG终端天线3发出的ATG上行信号与ATG基站3进行通信,同时ATG终端天线2上行信号将可能干扰IMT网络区域2的IMT基站,ATG终端天线3上行信号也将可能干扰IMT网络区域3的IMT基站。因此,ATG基站在为目标ATG终端提供通信服务时,可以获取该ATG基站对应的ATG终端天线的发射波束的宽度,具体的,ATG终端可以将为ATG基站发射射频信号的ATG终端天线的发射波束的宽度发送给ATG基站,ATG基站可以基于ATG终端天线的发射波束的宽度计算目标ATG终端到该ATG基站的上行信号所覆盖区域。
另外,ATG基站可以存储周边的各个IMT基站的具体信息,例如,IMT基站的位置信息等,在计算得到目标ATG终端到该ATG基站的上行信号所覆盖区域之后,可以确定该区域内都部署了哪些IMT基站,进一步的可以确定出该区域中IMT基站的数量。为了降低当ATG基站与ATG终端进行通信的频率与IMT基站对应的网络频率相同时,ATG终端到该ATG基站的上行信号干扰IMT基站对应的网络的可能性。
如图4所示,图4为本公开实施例提供的应用于航空移动通信系统的一种交互示意图。
图中所示的ATG基站是为ATG终端提供通信服务的ATG基站,邻 近基站为该ATG基站的邻近ATG基站,IMT基站为ATG终端到该ATG基站的上行信号覆盖区域中的IMT基站,ATG终端的信号频率与IMT基站的信号频率至少部分相同。
具体交互过程如下:

ATG终端的信号频率与IMT基站的信号频率至少部分相同,也就是说,航空移动通信中的ATG终端与地面IMT基站可以采用相同频率,以 此可以拓宽ATG终端可以使用的频率带宽,从而满足用户对航空移动业务带宽的需求。而且,当目标ATG终端需要切换ATG基站,当前为目标ATG终端提供通信服务的ATG基站基于其他基站至目标ATG终端的下行信号的信号质量、目标ATG终端到其他每一个ATG基站的上行信号所覆盖区域中IMT基站的数量确定出目标ATG基站,从而在目标ATG终端需要切换ATG基站时,可以基于其他基站至目标ATG终端的下行信号的信号质量、目标ATG终端到其他每一个ATG基站的上行信号所覆盖区域中IMT基站的数量从其他ATG基站中确定出合适的ATG基站。
且当ATG终端进行切换时,存在多个信号质量相当的目标ATG基站时,优先选择ATG终端到该邻近ATG基站上行信号所覆盖IMT网络基站数量较少的ATG基站作为目标ATG基站,从而降低当ATG基站与ATG终端进行通信的频率与IMT基站对应的网络频率相同时,ATG终端到该ATG基站的上行信号干扰IMT基站对应的网络的可能性。
