Description

位置确定方法、装置、通信设备和存储介质 技术领域
本申请涉及无线通信技术领域但不限于无线通信技术领域，尤其涉及位置确定方法、装置、通信设备和存储介质。
背景技术
地面移动通信已经进入第五代(5 th Generation)蜂窝移动通信时代，卫星通信和地面5G移动通信的融合将实现天地一体化网络。5G蜂窝移动通信网络中的非地面网络(NTN，Non-Terrestrial Networks)场景包括8个增强型移动宽带(eMBB，Enhanced Mobile Broadband)场景和2个大规模机器类通信(mMTC，Massive Machine Type Communication)场景。借助卫星的广域覆盖能力，可以使运营商在地面网络基础设施不发达地区提供5G商用服务，实现5G业务连续性，尤其是在应急通信、海事通信、航空通信及铁路沿线通信等场景中发挥作用。
在非地面网络场景中，由于卫星相对地面位置的快速变化，终端被同一颗卫星连续覆盖的时间只有十几分钟，对于采用多波束的低轨卫星，同一波束连续覆盖终端的时间只有几分钟，因此如何快速准确地进行切换是非地面网络场景中需要考虑的问题。

请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个终端11以及若干个基站12。
其中，终端11可以是指向用户提供语音和/或数据连通性的设备。终端11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，终端11可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)、移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment，UE)。或者，终端11也可以是无人飞行器的设备。或者，终端11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，终端11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。其中，该无线通信系统 可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，MTC系统。
其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站12的具体实现方式不加以限定。
基站12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，终端11之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13 可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
本公开实施例涉及的执行主体包括但不限于：支持蜂窝移动通信的空中接入网设备如基站等，以及核心网设备等。
本公开实施例的一种应用场景为，如图2所示，在地面网络系统中，UE在小区中央和小区边缘的测量得到的接收信号强度有较大差异，可以根据小区中央和小区边缘的接收信号强度的差异来判断UE是否在小区边缘，进而确定是否进行重选小区或切换小区。
如图3所示，对非地面网络系统中，由于传播距离比较长，低地球轨道(LEO，Low Earth Orbit)卫星高度可达300-1500公里，终端UE在小区中心和小区边缘测量的接收信号强度变化不大。如果非地面网络系统中采用原来5G NR的小区重选和RSRP/RSRQ测量上报机制，终端UE或者NTN基站(gNB)或者地面gNB很难准确判断终端UE是否处于小区边缘，在空闲态下很难准确判断在是否需要发起邻小区测量进行可能的小区重选，在连接态下，NTN gNB或者地面gNB很难准确判断是否需要发起小区切换过程。
如图4所示，本示例性实施例提供一种位置确定方法，可以应用于无线通信的UE中，位置确定方法可以包括：
步骤401：基于测量得到的空中接入网设备在服务小区发射的无线信号 的定位测量结果，确定所述UE相对于所述服务小区的位置关系；其中，所述定位测量结果指示所述UE相对于所述空中接入网设备的位置关系。
UE可以是采用蜂窝移动通信网络技术进行无线通信的手机终端等。空中接入网设备可以是蜂窝移动通信网络的NTN基站，如卫星，由高空气球携带的小型基站等。
测量结果可以是UE基于在服务小区内空中接入网设备的发射信号测量得到的UE与空中接入网设备的相对位置关系等，例如，UE可以测量空中接入网设备的发射信号的飞行时间(TOF，Time of Fly)和到达角度等，基于飞行时间可以确定UE与空中接入网设备的信号飞行距离，即UE与空中接入网设备的距离。
由于NTN基站的信号覆盖范围在空间上较为固定，如图3所示，NTN基站的信号覆盖范围呈现圆锥体的形状。UE可以基于信号的飞行时间和到达角度等测量结果，确定与NTN基站的相对位置关系，进而确定UE在所述服务小区中的位置。
示例性的，如图5所示，NTN基站在空中向地面发送无线信号，在地面形成UE的服务小区。服务小区的中心点可以是NTN基站在地面的垂直投影点。圆锥体信号覆盖范围中，锥棱与锥底的角度为β，如果UE接收到的无线信号的到达角度α大于或等于β，则认为UE在服务小区内部，如果α小于β则认为UE在服务小区外部。这里，锥棱与锥底的角度β可以根据NTN基站的波束确定。
UE可以测量NTN基站发射信号的飞行时长，NTN基站发射信号时，可以携带关于发射时间点的信息，UE基于信号的接收时间点和发射时间点可以确定信号的飞行时长，结合信号传播速度，可以确定信号的飞行时长。如图6所示，服务小区形成的圆锥体信号覆盖范围中，NTN基站发射的信号的最长飞行时长为圆锥体棱长，如果UE接收到的无线信号的飞行距离小 于或等于棱长，则认为UE在服务小区内部，如果飞行距离大于棱长，则认为UE在服务小区外部。这里，圆锥体棱长可以根据NTN基站的波束确定。
确定的UE与所述服务小区的位置关系可以用于确定是否需要切换小区等，这里，切换小区可以包括：在UE处于空闲态时进行小区重选，或，在UE处于连接态时进行小区切换。
这里，棱长和角度值β可以预先商定，也可以由空中接入网设备通过携带在系统消息中广播给UE，或者携带在RRC信令中发送给UE。
如此，针对NTN基站等移动空中接入网设备，通过测量服务小区无线信号确定UE与空中接入网设备的相对位置，进而确定UE与服务小区的位置关系，提高UE确定在服务小区内位置的精度。进而可以准确判断是否切换小区，减少采用无线信号接收强度等确定切换小区时机出现的不准确情况。
在一个实施例中，所述方法还包括：接收指示所述空中接入网设备的高度的位置指示信息；
所述基于测量得到的空中接入网设备在服务小区发射的无线信号的定位测量结果，确定所述UE相对于所述服务小区的位置关系，包括：
基于所述位置指示信息和所述定位测量结果，确定所述UE相对于所述服务小区中心点的距离。
位置指示信息可以用于指示NTN基站等空中接入网设备的位置，如：空中接入网设备的高度等。这里，空中接入网设备的高度可以是空中接入网设备到地面的垂线长度。NTN基站等指示空中接入网设备在向地面发送信号时，通常垂直向地面发射，因此，在地面形成圆形的信号覆盖区域。圆形的信号覆盖区域的中心，为空中接入网设备垂直投影点，同样也是小区的中心位置。此外，即使空中接入网设备不是垂直向地面发射无线信号的，其向地面发射无线信号的角度也可以是固定的，或是周期性变化的。 该角度可以通过无线信令实时地通知UE，或者也可以是预先为空中接入网设备或UE所知的(例如，通过通信协议)。空中接入网设备或UE可以根据该角度，结合空中接入网设备的高度，得到与空中接入网设备相关联的服务小区的中心位置，从而确定所述UE相对于所述服务小区中心点的距离。
NTN基站可以通过广播的系统消息或者RRC信令等携带位置指示信息，将位置指示信息发送给UE。
位置指示信息可以由NTN基站直接发送给UE，或者也可以由NTN基站的地面站，即地面基站，通过NTN基站发送给UE。
UE在服务小区内与NTN基站建立通信连接，NTN基站向UE发送指示信息指示NTN基站距地面的高度。
UE确定NTN基站距地面的高度后，UE可以基于信号的飞行时间和到达角度等测量结果，采用基于勾股定理等，确定UE到服务小区中的距离。
如此，可以实现UE到服务小区中的距离的准确计算，提高UE到服务小区中的距离计算的准确性。
在一个实施例中，所述基于所述位置指示信息和所述定位测量结果，确定所述UE相对于所述服务小区中心点的距离，包括至少以下之一：
基于所述空中接入网设备的高度和所述无线信号的到达角度，确定所述UE与所述服务小区中心点的距离；
基于所述空中接入网设备的高度和所述UE与所述空中接入网设备的距离，确定所述UE与所述服务小区中心点的距离。
如图7所示，在已知空中接入网设备的高度，和空中接入网设备发射的无线信号的到达角度的前提下，可以基于三角函数关系等，确定UE与服务小区中心的距离。
如图6所示，UE可以根据自身的定位信息以及从星历表等中查询得到 的卫星等空中接入网设备的位置，确定UE与空中接入网设备的距离。例如，UE的定位信息是通过全球定位系统(GPS)、北斗定位系统(BDS)等卫星定位系统得到的，或者是由基站或其他网络侧设备通知的该终端的大致位置得到的。在已知空中接入网设备的高度，和空中接入网设备发射与UE之间的距离的前提下，可以基于勾股定理等，确定UE与服务小区中心的距离。
如此，可以实现UE到服务小区中的距离的准确计算，提高UE到服务小区中的距离计算的准确性。
在一个实施例中，所述UE与所述空中接入网设备的距离是基于所述无线信号的飞行时间来确定的。
UE可以测量空中接入网设备发射的无线信号的飞行时间，空中接入网设备可以在无线信号中携带该无线信号的发射时间信息，UE根据接收该无线信号的接收时间和发射时间确定无线信号的飞行时间。UE可以根据无线信号的飞行时间确定无线信号的飞行距离，即UE与空中接入网设备的距离。
在一个实施例中，所述方法可以包括：
基于所述UE相对于所述服务小区的位置关系，确定是否进行邻小区测量，或者确定进行邻小区测量的频度。
例如，当基于UE相对于所述服务小区的位置关系，确定UE位于距离服务小区的边缘一定距离之内时(例如，UE距小区边缘的距离小于一个阈值)，则可以使得UE进行邻小区测量，或者可以使得UE增加邻小区测量的频度。而随着UE越来越远离服务小区边缘而靠近服务小区中心时，可以逐渐降低邻小区测量的频度，或在UE距离服务小区中心一定范围内时，不进行邻小区测量。从而达到节省终端电量的目的。
在一个实施例中，所述方法可以包括：
基于所述UE相对于所述服务小区的位置关系，确定是否进行小区的切换。
这里，可以根据UE与所述服务小区的位置关系，确定是否进行小区的切换。
例如，如图5所示，当无线信号的到达角度α减β之差小于角度阈值时，则确定UE接近服务小区边缘，可以切换小区。
如图6所述，如果UE接收到的无线信号的飞行距离小于棱长，并且棱长与无线信号飞行距离之差小于预定的距离阈值，则确定UE接近服务小区边缘，可以切换小区。
这里，角度阈值和预定的距离阈值可以预先商定，也可以由空中接入网设备通过携带在系统消息中广播给UE，或者携带在RRC信令中发送给UE。
当UE处于连接态，如果需要进行切换小区，可以向空中接入网设备发送切换请求，由空中接入网设备确定是否进行小区切换。
当UE处于空闲态，如果确定UE接近服务小区边缘，可以切换小区，可以由UE确定进行小区重选。UE进行小区重选时，可以首先进行邻小区的无线信号测量，UE可以将无线信号测量结果满足切换条件的邻小区确定为新的服务小区进行随机接入。
在一个实施例中，所述基于所述UE相对于所述服务小区的位置关系，确定是否进行小区的切换，包括以下之一：
响应于所述UE处于空闲态，并且所述UE与所述服务小区中心点的距离大于距离阈值，进行小区重选；

如图8所示，本示例性实施例提供一种位置确定方法，可以应用于无线通信的空中接入网设备中，位置确定方法可以包括：
步骤801：发送指示所述空中接入网设备的高度的位置指示信息，其中，所述位置指示信息，用于确定UE与服务小区的位置关系。
UE可以是采用蜂窝移动通信网络技术进行无线通信的手机终端等。空 中接入网设备可以是移动空中接入网设备。移动空中接入网设备可以是蜂窝移动通信网络的NTN基站，如卫星，由高空气球携带的小型基站等。
测量结果可以是UE基于在服务小区内空中接入网设备的发射信号测量得到的UE与空中接入网设备的相对位置关系等，例如，UE可以测量空中接入网设备的发射信号的飞行时间(TOF，Time of Fly)和到达角度等。
位置指示信息可以用于指示NTN基站等空中接入网设备的位置，如：空中接入网设备的高度等。这里，空中接入网设备的高度可以是空中接入网设备到地面的垂线长度。NTN基站等指示空中接入网设备在向地面发送信号时，通常垂直向地面发射，因此，在地面形成圆形的信号覆盖区域。圆形的信号覆盖区域的中心，为空中接入网设备垂直投影点，同样也是小区的中心位置。
NTN基站可以通过广播的系统消息或者RRC信令等携带位置指示信息，将位置指示信息发送给UE。
位置指示信息可以由NTN基站直接发送给UE，或者也可以由NTN基站的地面站，即地面基站，通过NTN基站发送给UE。
UE在服务小区内与NTN基站建立通信连接，NTN基站向UE发送指示信息指示NTN基站距地面的高度。
UE确定NTN基站距地面的高度后，UE可以基于信号的飞行时间和到达角度等测量结果，采用基于勾股定理等，确定UE到服务小区中的距离。
示例性的，如图5所示，NTN基站在空中向地面发送无线信号，在地面形成UE的服务小区。服务小区的中心点可以是NTN基站在地面的垂直投影点。圆锥体信号覆盖范围中，锥棱与锥底的角度为β，如果UE接收到的无线信号的到达角度α大于或等于β，则认为UE在服务小区内部，如果α小于β则认为UE在服务小区外部。这里，锥棱与锥底的角度β可以根据NTN基站的波束确定。
UE可以测量NTN基站发射信号的飞行时长，NTN基站发射信号时，可以携带关于发射时间点的信息，UE基于信号的接收时间点和发射时间点可以确定信号的飞行时长，结合信号传播速度，可以确定信号的飞行时长。如图6所示，服务小区形成的圆锥体信号覆盖范围中，NTN基站发射的信号的最长飞行时长为圆锥体棱长，如果UE接收到的无线信号的飞行距离小于或等于棱长，则认为UE在服务小区内部，如果飞行距离大于棱长，则认为UE在服务小区外部。这里，圆锥体棱长可以根据NTN基站的波束确定。
如图7所示，在已知空中接入网设备的高度，和空中接入网设备发射的无线信号的到达角度的前提下，可以基于三角函数关系等，确定UE与服务小区中心的距离。
如图6所示，UE可以根据自身的定位信息以及从星历表等中查询得到的卫星等空中接入网设备的位置，确定UE与空中接入网设备的距离。在已知空中接入网设备的高度，和空中接入网设备发射与UE之间的距离的前提下，可以基于勾股定理等，确定UE与服务小区中心的距离。

在一个实施例中，所述无线信号的测量结果包括：所述无线信号的到达角度和/或所述无线信号的飞行时间。
在一个实施例中，所述无线信号的测量结果包括：所述无线信号的到达角度和/或所述无线信号的飞行时间。

如图6所示，可以根据空中接入网设备发射的无线信号的飞行时间，确定空中接入网设备到UE之间的直线距离，即无线信号的飞行距离。在已知空中接入网设备的高度，和空中接入网设备与UE之间的距离的前提下，可以基于勾股定理等，确定UE与服务小区中心的距离。该距离的确定方法在描述终端侧技术方案时已详细描述，再此不再赘述。
如此，可以实现UE到服务小区中的距离的准确计算，提高UE到服务小区中的距离计算的准确性。
在一个实施例中，所述方法可以包括：
基于所述UE相对于所述服务小区的位置关系，确定是否指示UE进行邻小区测量，或者指示UE提高进行邻小区测量的频度。
例如，当基于UE相对于所述服务小区的位置关系，确定UE位于距离服务小区的边缘一定距离之内时(例如，UE距小区边缘的距离小于一个阈 值)，则可以使得UE进行邻小区测量，或者可以使得UE增加邻小区测量的频度。而随着UE越来越远离服务小区边缘而靠近服务小区中心时，可以逐渐降低UE进行邻小区测量的频度，或指示UE在距离服务小区中心一定范围内时，不进行邻小区测量。从而达到节省终端电量的目的。
在一个实施例中，空中接入网设备可以通过RRC信令或DCI信令等控制信令，来指示UE是否进行邻小区测量，或携带UE进行与邻小区测量的频度相关联信息。例如，该信息可以指示UE进行邻小区测量的特定频度，或指示UE相对于当前的邻小区测量频度应增加或降低的偏移值，或指示UE提高或降低特定步长的邻小区测量频度。
在一个实施例中，所述方法可以包括：

在一个实施例中，所述方法还包括：
响应于所述UE在所述服务小区中的位置满足切换条件，对所述UE进行小区切换。
当空中接入网设备判定UE是否位于服务小区边缘时，空中接入网设备可以启动小区切换流程，指示UE进行邻小区的无线信号测量。并基于UE上报的邻小区的无线信号测量结果选择满足条件的邻小区作为UE新的服务小区。
本公开还公开了一种邻小区测量的方法，可以应用于空中接入网设备，包括，空中接入网设备确定UE相对于与空中接入网设备相关联的服务小区的位置关系；基于所述UE相对于所述服务小区的位置关系，确定是否指示UE进行邻小区测量，或者确定指示UE进行邻小区测量的频度。例如，当 基于UE相对于所述服务小区的位置关系，确定UE位于距离服务小区的边缘一定距离之内时(例如，UE距小区边缘的距离小于一个阈值)，则可以指示UE进行邻小区测量，或者可以指示UE增加邻小区测量的频度。而随着UE越来越远离服务小区边缘而靠近服务小区中心时，可以逐渐降低邻小区测量的频度，或在UE距离服务小区中心一定范围内时，指示UE不进行邻小区测量。通过该方法，可以达到节省终端电量的目的。
在一个实施例中，空中接入网设备可以通过RRC信令或DCI信令等控制信令，来指示UE是否进行邻小区测量，或携带UE进行与邻小区测量的频度相关联信息。例如，该信息可以指示UE进行邻小区测量的特定频度，或指示UE相对于当前的邻小区测量频度应增加或降低的偏移值，或指示UE提高或降低特定步长的邻小区测量频度。
以下结合上述任意实施例提供一个具体示例：
判定NTN小区边界的机制如下所述：
1：在波束随着卫星移动的场景中，卫星向所覆盖的区域广播卫星高度信息，并把小区中心位置作为与终端UE的参考点；

周期性上报方式：终端UE周期性向NTN gNB或者地面gNB上报位置信息，NTN gNB或者地面gNB通过上报的位置信息与小区中心位置信息进行比较，判定UE是否位于小区边缘；
事件触发上报方式：当UE与小区中心位置参考点的距离差大于位置门 限值时，则判定UE处于小区边缘，终端UE上报小区边缘指示信息。
4：在idle态下，NTN gNB或者地面gNB通过广播信令或者RRC测量配置信令的方式向UE配置小区边界判定的位置门限值，当UE与小区中心位置参考点的距离差大于位置门限值时，则判定UE处于小区边缘，触发邻小区测量；
在idle态下，通过设定不同的位置门限值判断UE是处于小区边缘区域还是小区中心区域，当终端UE被认为是处于小区边缘区域时，则UE触发邻小区测量，当终端UE被认为是处于小区中心区域，终端UE可不对邻小区进行测量以便节省功率，如图三所示。
