图1示例性地示出了一种本申请应用的通信系统100的示意图。如图1所示,该通信系统100主要包括终端设备(User Equipment,UE)101、接入网(Access Network,AN)设备102、接入与移动性管理功能(Access and Mobility Management Function,AMF)实体103、会话管理功能(Session Management Function,SMF)实体104、用户面功能(User Plane Function,UPF)实体105、策略控 制功能(Policy Control function,PCF)实体106、统一数据管理(Unified Data Management,UDM)实体107、数据网络(Data Network,DN)108、应用功能(Application Function,AF)实体109、鉴权服务器功能(Authentication Server Function,AUSF)实体110、网络切片选择功能(Network Slice Selection Function,NSSF)实体111。

本申请实施例结合终端设备和网络设备描述了各个实施例,其中:终端设备也可以称为用户设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置等。终端设备可以是WLAN中的站点(STAION,ST),可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及下一代通信系统,例如,NR网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)网络中的终端设备等。
作为示例而非限定,在本申请实施例中,该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备,是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称,如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上,或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备,更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能,例如:智能手表或智能眼镜等,以及只专注于某一类应用功能,需要和其它设备如智能手机配合使用,如各类进行体征监测的智能手环、智能首饰等。
上述AN设备102可以是用于与移动设备通信的设备,AN设备102可以是WLAN中的接入点(Access Point,AP),GSM或CDMA中的基站(Base Transceiver Station,BTS),也可以是WCDMA中的基站(NodeB,NB),还可以是LTE中的演进型基站(Evolutional Node B,eNB或eNodeB),或者中继站或接入点,或者车载设备、可穿戴设备以及NR网络中的基站(gNB)或者未来演进的PLMN 网络中的网络设备等。
在本申请实施例中,网络设备为小区提供服务,终端设备通过该小区使用的传输资源(例如,频域资源,或者说,频谱资源)与网络设备进行通信,该小区可以是网络设备(例如基站)对应的小区,小区可以属于宏基站,也可以属于小小区(Small cell)对应的基站,这里的小小区可以包括:城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等,这些小小区具有覆盖范围小、发射功率低的特点,适用于提供高速率的数据传输服务。
随着移动通信技术的发展,接入第三代合作伙伴计划(The 3rd Generation Partnership Project,3GPP)移动通信网络的终端设备已经不限于人们手持的终端设备。越来越多的机器设备例如无人机也将成为广泛的无线通信网络使用场景。无人机等设备在接入3GPP网络时,也是作为终端设备接入,如图2所示,无人机(Unmanned Aerial Vehicle,UAV)接入3GPP网络之后,可以通过3GPP网络建立与无人机管理中心(Unmanned Aerial System Traffic Management,UTM)的连接,UTM负责无人机的注册、位置跟踪等管理功能,并可以控制无人机的例如飞行路线等行为。无人机接入3GPP网络之后,还可以通过3GPP网络建立与无人机控制器之间的连接,由无人机控制器控制无人机的行为。
在无人机的飞行过程中,地理围栏是一种重要的管控方式。例如可以设置禁飞区,无人机需要知道禁飞区的范围,从而避免在禁飞区飞行,一旦无人机飞入禁飞区,UTM会采取相应的管控措施,例如接管无人机控制器对无人机的操控,控制无人机飞离禁飞区,或者通知权威第三方实体(Third Party Authorized Entity,TPAE)接管对无人机的操控或者监控,TPAE例如可以是归属于公安系统的无人机控制器。
地理围栏可以在应用层实现,也就是UTM可以通过应用层的数据交互将地理围栏信息配置在UAV侧,当UAV飞入到禁飞区时,UTM采取相应的管控措施,例如收回飞行授权,或者通知TPAE进行管控等。考虑UAV通过3GPP网络接入的情况,禁飞区的设置对于3GPP网络是透明的,也就是说3GPP网络并不了解地理围栏信息的存在,从而可能发生将正常飞行的UAV的数据通路切换到禁飞区的网络设备,导致UAV信号中断等情况的发生,并且因为UTM依赖3GPP网络提供的UAV位置信息,例如UAV在3GPP网络所处的小区标识,来确定UAV的实际位置,这也会造成UTM错误地将正常飞行的UAV认为是飞行在禁飞区的UAV,从而采取错误的管控措施。
基于上述问题,本申请提出在3GPP网络中引入地理围栏区域的概念,使得3GPP网络可以获得UAV的地理围栏区域信息,例如禁飞区信息,UAV的地理围栏区域信息可以发送到终端设备、基站、AMF实体、SMF实体,从而使3GPP网络更好的服务于无人机接入的管控。

步骤22,UAV向源基站进行测量报告。
步骤23,源基站根据测量报告判断需要将UAV切换到其他基站/小区。源基站为UAV选择目标基站/目标小区时,需要考虑地理围栏区域信息,例如优先选择位于允许飞行区域的小区,避免将UAV切换到位于禁止飞行区域的小区。
