以下，对本发明的相关技术给出说明。
飞行路径
UE的AS层可能通过上层(例如应用层)获取到自己的飞行路径(flight path)。所述飞行路径可以包括但不限于路径上的途经点(waypoint)列表。所述途经点列表中的每个途经点的信息可以包括但不限于：途经点的位置信息，到达途经点的时间信息。途经点的位置信息可以由椭球三维坐标的相关信息表示。到达途径点的时间信息可以是UE打算/预计到达该途经点的时间信息，所述时间信息可以是绝对时间(例如：UTC时间)。
飞行路径报告
在RRC连接建立流程中，UE在收到网络发送的RRC建立(RRCSetup)消息后，如果所述UE有可获得的飞行路径，则所述UE在发送给网络的RRC建立完成(RRCSetupComplete)消息中包含飞行路径信息可获得指示(flightPathInfoAvailable)，用于指示飞行路径信息可获得(例如flightPathInfoAvailable置为TRUE)。类似的，在RRC连接重配置流程中，UE在收到网路发送的RRC重配(RRCReconfiguration)消息后，如果所述UE有可获得的飞行路径，则所述UE在发送给网络的RRC重配完成(RRCReconfigurationComplete)消息中包含飞行路径信息可获得指示(flightPathInfoAvailable)，用于指示飞行路径信息可获得。在RRC连接恢复流程中，UE在收到网路发送的RRC恢复(RRCResume)消息后，如果所述UE有可获得的飞行路径，则所述UE在发送给网络的RRC重配完成(RRCResumeComplete)消息中包含飞行路径信息可获得指示(flightPathInfoAvailable)，用于指示飞行路径信息可获得。在RRC连接重建流程中，UE在收到网路发送的RRC重建(RRCReestablishment)消息后，如果所述UE有可获得的飞行路径，则所述UE在发送给网络的RRC重配完成(RRCReestablishmentComplete)消息中包含飞行路径信息可获得指示(flightPathInfoAvailable)，用于指示飞行路径信息可获得。
网络侧可以根据UE在上述流程中上报的飞行路径信息可获得指示(flightPathInfoAvailable)，确定是否要求UE上报飞行路径。UE接收网络发送的UE信息请求(UEInformationRequest)消息。如果所述UEInformationRequest消息中包含飞行路径信息请求(flightPathInfoReq)配置，并且如果所述UE有可获得的飞行路径信息，则所述UE在UE信息响应(UEInformationResponse)消息中包含飞行路径信息报告(flightPathInfoReport)，并且将所述飞行路径信息报告设置为包含所述飞行路径沿途的途经点列表。进一步的，flightPathInfoReq配置中可能包含但不限于如下配置：最大途经点个数，包含时间戳指示(includeTimeStamp)。所述flightPathInfoReport中的途经点列表中的途经点个数不超过最大途经点个数。如果flightPathInfoReq中包含includeTimeStamp(并且includeTimeStamp被设置为TRUE)，如果时间戳信息在所述UE侧是可获得的，则所述UE将flightPathInfoReport中的时间戳(timeStamp)域设置为所述UE打算/预计到达的每个途经点的时间。所述UE将UEInformationResponse消息递交给底层传输。
时间戳信息只有在网络侧配置了需要包含时才会包含在UE上报的飞行路径信息报告中，否则飞行路径信息报告中不包含时间戳信息。这是由网络需要UE上报飞行路径的用途决定的，例如在网络只是利用UE的飞行路径报告确定小区范围如何划分等情况下，网络可能就不需要飞行路径中的途经点的时间戳信息，而只需要飞行路径中的途经点的位置信息。
飞行路径变更
对于NR UAV，如果飞行路径发生变更，UE可以向网络发送变更指示信息。网络收到UE发送的变更指示信息后，可以通过向UE发送UEInformationRequest消息要求UE上报飞行路径报告。由于飞行路径中的途经点信息可以包括途经点的位置信息和到达途经点的时间信息，飞行路径变更存在多种可能性：飞行路径的位置信息没有发生变更而时间信息发生变更；飞行路径的位置信息发生变更而时间信息没有发生变更；飞行路径的位置信息和时间信息都发生变更。
针对飞行路径变更的多种情况，本发明讨论UE如何判断飞行路径发生变更以及飞行路径发生变更后如何指示给网络，一方面让网络能够及时地获知到UE的飞行路径用于网络规划和对UE的移动控制和调度控制等用途； 另一方面也避免不必要的变更指示和飞行路径上报，减少无线资源的浪费和节省功耗。
以下，详细描述本发明对于上述问题的若干实施例。
