Description
本发明涉及通信技术领域，尤其涉及一种位置关系确定方法及装置。
无人驾驶飞机，简称无人机(UAV，Unmanned Aerial Vehicle)，是指利用无线电遥控设备和自备的程序控制装置操纵的不载人飞行器。无人机实际上是无人驾驶飞行器的统称，从技术角度定义可以将无人机分为：无人固定翼机、无人垂直起降机、无人飞艇、无人直升机、无人多旋翼飞行器、无人伞翼机等。而随着无人机技术的快速发展、成本的降低以及功能的完善，无人机越来越多的应用于普通消费者群体中。而无人机+行业应用，是无人机真正的刚需；目前无人机在航拍、农业、植保、微型自拍、快递运输、灾难救援、观察野生动物、监控传染病、测绘、新闻报道、电力巡检、救灾、影视拍摄、制造浪漫等领域的应用，极大地拓展了无人机本身的用途，许多国家都在积极发展无人机技术与扩展行业应用。
为了进一步拓展无人机的应用范围，第三代合作伙伴计划(3GPP，3rd Generation Partnership Project)通过了“Enhanced Support for Aerial Vehicles”立项，旨在研究并标准化如何能够使蜂窝网络为无人机提供满足需求的服务。无人机飞行一般有两种模式：一种为固定模式，是指操控者会在控制器上规划好无人机的飞行线路，这样无人机就可以按照规划好的路线飞行，控制器也不用时时刻刻对无人机进行控制；另一种模式为动态模式，是指控制者会通过控制器对无人机进行实时的遥控。而针对于固定模式，由于无人机的飞行路线和轨迹是固定的，因此，蜂窝网络可以预判无人机会经过哪些蜂窝网络基站。
当前，以3GPP为代表的研究机构认为无人机的飞行路径会对提升无人机的移动性产生帮助；然而，相关技术中并未给出如何基于无人机的飞行路径来提升无人机的移动性。

为了能够实现基于无人机的飞行路径提升无人机的移动性，蜂窝网络的基站在获得无人机的飞行路径后，还需要判定相邻基站是否在无人机的飞行路径上；然而，相关技术中并未给出如何判定相邻基站是否在无人机的飞行路径上的解决方案，这就无法实现基于无人机的飞行路径提升无人机的移动性，限制了无人机的移动性提升空间。
为了解决上述问题，本发明实施例提供了一种位置关系确定方法，方法包括：获取无人机的飞行路径信息；获取与源基站相邻的邻基站的位置信息；在邻基站的位置信息与无人机的飞行路径信息匹配时，确定邻基站位于无人机的飞行路径上。本发明实施例提供的位置关系确定方法，通过获取邻基站的位置信息，在邻基站的位置信息与无人机的飞行路径信息匹配时，确定邻基站位于无人机的飞行路径上，解决了如何判定相邻基站是否在无人机的飞行路径上的问题，这就可以提前通知邻基站预先为优化无人机的移动性做准备，例如邻基站可以提前为无人机预留资源，有助于解决无人机的移动性提升问题。
本发明实施例记载的技术方案可以用于判断邻基站是否位于无人机的飞行路径上；参见图1示出的本发明实施例中位置关系确定方法的一个可选的应用场景；图1所示的应用场景中涉及：无人机控制设备11、无人机12、蜂窝网络的基站13、蜂窝网络的基站14及网络15；其中，无人机控制设备11例如可以是无人机专用控制器，也可以是安装有无人机控制软件的智能手机、平板电脑或穿戴式设备(如手环)等设备；基站14为基站13的邻基站；无人机控制设备11通过有线或无线的方式接入到网络15；无人机12当前已接入基站13；蜂窝网络例如是2G/3G/4G/5G网络；用户使用无人机控制设备11，借助蜂窝网络可以远程操控无人机12。图1中示出的应用场景仅是本发明实施例记载的技术方案的一个可能的应用场景示例，其他应用场景可以包括图1未涉及的设备和网络。
基于上述分析，提出以下各具体实施例。
图2是根据一示例性实施例示出的一种位置关系确定方法的流程图，该位置关系确定方法可以应用于蜂窝网络的基站中，该方法的执行主体可以为源基站。如图2所示，该方法包括以下步骤201-203：

示例的，源基站获取到无人机的飞行路径信息时，经由源基站与邻基站之间的基站间接口，向邻基站发送无人机的飞行路径信息。例如，源基站获取到无人机的飞行路径信息时，通过X2接口向邻基站发送基站配置更新(ENB CONFIGURATION UPDATE)信令，在ENB CONFIGURATION UPDATE信令中携带无人机的飞行路径信息；邻基站接收到ENB
CONFIGURATION UPDATE之后，解析ENB CONFIGURATION UPDATE得到无人机的飞行路径信息，然后，邻基站向源基站回复基站配置更新确认(ENB CONFIGURATION UPDATE ACKNOWLEDGE)。邻基站获取到无人机的飞行路径信息之后，通过获取与邻基站相邻的其他基站的位置信息，在与邻基站相邻的其他基站中搜索位于无人机的飞行路径上的目标基站，这就可以提前通知目标基站预先为优化无人机的移动性做准备，例如目标基站可以提前为无人机预留资源，有助于解决无人机的移动性提升问题。
在步骤202中，获取与源基站相邻的邻基站的位置信息；
示例的，步骤201与步骤202的执行不分先后，可以先执行步骤201再执行步骤202，也可以先执行步骤202再执行步骤201，或者，同时执行步骤201与步骤202，本发明对此不做限定。

或者，源基站也可以向邻基站请求邻基站的位置信息，例如，源基站可以向邻基站发送位置信息请求消息，其中，位置信息请求消息用于请求邻基站向源基站发送邻基站的位置信息；源基站在接收到位置信息请求消息时，向源基站发送位置信息响应消息，其中，位置信息响应消息中包括邻基站的位置信息；源基站接收邻基站发送的位置信息响应消息，通过解析位置信息响应消息，得到邻基站的位置信息。
示例的，源基站向邻基站请求邻基站的位置信息的实现方式至少可以包括以下任意一种方式：
方式1)基站和邻基站可以在建立基站间接口建立过程中通过接口信令交互各自的位置信息。例如，源基站在建立源基站与邻基站之间的基站间接口时，向邻基站发送位置信息互换请求消息，其中，位置信息互换请求消息中包括源基站的位置信息；邻基站接收到信息互换请求消息时，向源基站发送位置信息互换响应消息，其中，位置信息互换响应消息中包括邻基站的位置信息；源基站接收邻基站发送的位置信息互换响应消息，获得邻基站的位置信息。基站间接口例如X2接口。
例如，源基站和邻基站通过接口信令X2建立请求(X2 SETUP REQUEST)信令和X2建立响应(X2 SETUP RESPONSE)信令，达到交互各自的位置信息的目的；具体地，源基站在建立源基站与邻基站之间的X2接口时，向邻基站发送X2 SETUP REQUEST，其中，X2 SETUP REQUEST中包括源基站的位置信息；邻基站接收到X2 SETUP REQUEST时，向源基站发送X2 SETUP RESPONSE，其中，X2 SETUP RESPONSE中包括邻基站的位置信息；源基站接收邻基站发送的邻基站的位置信息，获得邻基站的位置信息。
示例的，源基站获取源基站的位置信息的实现方式可以包括：1)调用卫星定位系统对源基站进行定位，得到源基站的位置信息；2)向OAM系统发送携带源基站标识的位置请求，及接收OAM系统发送的源基站的位置信息。
示例的，邻基站获取邻基站的位置信息的实现方式可以包括：1)调用卫星定位系统对邻基站进行定位，得到邻基站的位置信息；2)向OAM系统发送携带邻基站标识的位置请求，及接收OAM系统发送的邻基站的位置信息。
方式2)基站和邻基站可以在基站间接口建立之后进行位置信息的传递。例如，源基站在获取到无人机的飞行路径信息时，向邻基站发送资源状态请求(RESOURCE STATUS REQUEST)，其中，RESOURCE STATUS REQUEST中包括用以请求邻基站位置信息的指示信息，可选的，源基站通过X2接口向邻基站发送RESOURCE STATUS REQUEST；邻基站接收到RESOURCE STATUS REQUEST，根据指示信息向源基站发送携带邻基站的位置信息的资源状态响应(RESOURCE STATUS RESPONSE)，可选的，邻基站通过X2接口向源基站返回RESOURCE STATUS RESPONSE；源基站接收邻基站发送的RESOURCE STATUS RESPONSE，获得邻基站的位置信息。
在步骤203中，在邻基站的位置信息与无人机的飞行路径信息匹配时，确定邻基站位于无人机的飞行路径上。
示例的，获取到邻基站的位置信息之后，判断邻基站的位置信息与无人机的飞行路径信息是否匹配：在邻基站的位置信息与无人机的飞行路径信息匹配时，确定邻基站位于无人机的飞行路径上；在邻基站的位置信息与无人机的飞行路径信息不匹配时，流程结束。
示例的，判断邻基站的位置信息与无人机的飞行路径信息是否匹配的步骤可以包括：根据邻基站的位置信息，确定邻基站相对于无人机的飞行路径的偏离值；判断偏离值是否小于预设阈值：在偏离值小于预设阈值时，确定邻基站位于无人机的飞行路径上；在偏离值大于等于预设阈值时，确定邻基站不在无人机的飞行路径上。
示例的，在确定邻基站位于无人机的飞行路径上时，向邻基站发送无线资源预留指示，其中，无线资源预留指示用于指示邻基站为无人机预留无线资源；邻基站接收到无线资源预留指示时，为无人机预留无线资源，能够提高无人机切换至邻基站的切换成功率，提升无人机的移动性。
采用本发明实施例提供的技术方案，通过获取邻基站的位置信息，在邻基站的位置信息与无人机的飞行路径信息匹配时，确定邻基站位于无人机的飞行路径上，解决了如何判定相邻基站是否在无人机的飞行路径上的问题，这就可以提前通知邻基站预先为优化无人机的移动性做准备，例如邻基站可以提前为无人机预留资源，有助于提升无人机的移动性，如此，能够提高用户体验。
