技术领域

背景技术
目前第四代移动通信技术(the 4th Generation mobile communication technology,4G)/第五代移动通信技术(the 5th Generation mobile communication technology,5G)依赖无线接入技术(Radio Access Technology dependent,RAT dependent)定位方法,都是通过多传输接收点(Transmission-Reception Point,TRP)的收发来实现的,通常每个cell下都会部署多个TRP。
但卫星系统中,具体的网络覆盖是由卫星实现的,TRP的部署只可能在卫星端。另外,卫星互联网系统中,地面形成的是类似蜂窝网络的覆盖,尤其是对低轨星座,很难要求UE始终在多颗卫星的有效覆盖范围内,很难实现多星定位。
因此当前的4G/5G RAT dependent定位方法难以应用于卫星互联网系统。

参见图1a,来自UE/LCS client/AMF的LCS定位业务请求,通过AMF发送给LMF,因此开启了LMF定位业务。LMF通过3a、3b步骤最终获得了终端的位置信息,通过步骤4发送给AMF,携带终端位置等信息。
LTE定位协议(LTE Positioning Protocol,LPP)上行定位流程
RAT相关的上行定位方法,包括上行链路到达时间差(Uplink Time Difference Of Arrival,UL-TDOA)和上行链路到达角度(Uplink Angel Of Arrival,UL-AOA)。在这两种定位方法中,服务基站和多个TRPs会基于从定位服务器LMF获取的辅助数据信息,同时对UE传输的探测参考信号(Sounding Reference Signal,SRS)进行接收和测量,包括针对上行链路传输的水平到达角(Azimuth Angel Of Arrival,A-AoA),上行链路传输的垂直到达角(Zenith Angel Of Arrival,Z-AoA),相对到达时间(Relative Time of Arrival,RTOA)以及参考信号接收功率(Reference Signal Receiving Power,RSRP)等的测量。服务基站和多个TRPs会将其测量结果传递给定位服务器LMF,由LMF基于SRS测量结果和其它配置信息来进行最终的位置计算。
具体的上行定位流程如图1b所示,包括以下步骤:
步骤0:LMF可能使用LMF触发的TRP Information Exchange Procedure获取上行定位(UL AOA或UL TDOA)所需的TRP信息。
步骤1:LMF可能基于LPP协议获取目标UE的定位能力。
步骤2:LMF向服务gNB发送NRPPa POSITIONING INFORMATION REQUEST信令,请求目标UE的上行SRS配置信息。
步骤3:服务gNB确定可用的上行SRS资源分配,并通过步骤3a为目标UE配置上行SRS资源集合。
步骤4:服务gNB通过NRPPa POSITIONING INFORMATION RESPONSE信令向LMF上报上行SRS的配置信息。
步骤5:LMF可能请求激活UE SRS传输,向目标UE的服务gNB发送NRPPa POSITIONING ACTIVATION REQUEST消息,包括要激活的SP SRS资源或者Aperiodic SRS资源。随后,gNB激活上行SRS传输。目标UE根据上行SRS资源配置,开始传输上行SRS。所述SRS的时域行为由gNB配置。
步骤6:LMF通过NRPPa MEASUREMENT REQUEST信令向选定的多个gNB发送上行SRS配置信息。所述的配置信息包括gNB/TRP执行上行测量的所有信息。
步骤7:步骤6中配置的每个gNB执行上行SRS的测量。
步骤8:每个gNB通过NRPPa Measurement Response信令向LMF上报上行SRS测量结果。
步骤9:针对SP SRS或AP SRS的情况,LMF向服务gNB发送NRPPa POSITIONING DEACTIVATION消息以停止SP SRS或AP SRS的传输。
参见图1c,基站配置SRS信号流程如图1c所示。
请参见图1d,图1d是本公开实施可应用的网络构架的结构示意图,如图1d所示,包括终端11,卫星12和卫星信关站13,其中:
需要说明的是,图1d中示出的是单个卫星12沿移动方向在不同时刻处于不同位置的场景,即如图1d所示,卫星12在T0、T1、T2、T3分别处于不同的位置。
在实际应用场景中,卫星信关站13可以设置在网络设备附近,用于从网络设备获取通信数据,然后将通信数据发送给卫星12,通过卫星12将通信数据发送给终端11,同理,终端的通信数据也可以通过卫星12发送给卫星信关站13,然后发送给网络设备,实现卫星互联网下的通信数据传输。
其中,本公开实施例涉及的终端11,可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备等。在不同的系统中,终端设备的名称可能也不相同,例如在5G系统中,终端设备可以称为用户设备(User Equipment,UE)。无线终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网(Core Network,CN)进行通信,无线终端设备可以是移动终端设备,如移 动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(Session Initiated Protocol,SIP)话机、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)、Redcap终端等设备。无线终端设备也可以称为系统、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(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户装置(user device),本公开实施例中并不限定。
本公开实施例涉及的网络设备,可以是基站,该基站可以包括多个为终端提供服务的小区。根据具体应用场合不同,基站又可以称为接入点,或者可以是接入网中在空中接口上通过一个或多个扇区与无线终端设备通信的设备,或者其它名称。网络设备可用于将收到的空中帧与网际协议(Internet Protocol,IP)分组进行相互更换,作为无线终端设备与接入网的其余部分之间的路由器,其中接入网的其余部分可包括网际协议(IP)通信网络。网络设备还可协调对空中接口的属性管理。例如,本公开实施例涉及的网络设备可以是全球移动通信系统(Global System for Mobile communications,GSM)或码分多址接入(Code Division Multiple Access,CDMA)中的网络设备(Base Transceiver Station,BTS),也可以是带宽码分多址接入(Wide-band Code Division Multiple Access,WCDMA)中的网络设备(NodeB),还可以是长期演进(long term evolution,LTE)系统中的演进型网络设备(evolutional Node B,eNB或e-NodeB)、5G网络架构(next generation system)中的5G基站(gNB)、6G中的基站,也可以是家庭演进基站(Home evolved Node B,HeNB)、中继节点(relay node)、家庭基站(femto)、微微基站(pico)等,本公开实施例中并不限定。在一些网络结构中,网络设备可以包括集中单元(centralized unit,CU)和分布单元(distributed unit,DU),集中单元和分布单元也可以地理上分开布置。在一些网络结构中,网络设备可以包括发送接收点 (Transmitting Receiving Point,TRP)。
目前4G/5G RAT dependent定位方法,都是通过多TRP的收发来实现的,通常每个cell下都会部署多个TRP。但卫星系统中,具体的网络覆盖是由卫星实现的,TRP的部署只可能在卫星端。另外,卫星互联网系统中,地面形成的是类似蜂窝网络的覆盖,尤其是对低轨星座,很难要求UE始终在多颗卫星的有效覆盖范围内,很难实现多星定位。
当前的4G/5G RAT dependent定位方法难以直接应用于卫星互联网系统,尤其是低轨星座的场景下,需要设计一种基于单星的定位方法。
此外,传统的RAT-dependent DL定位方法,LMF提前知道网络中的TRP的部署情况,以及每个TRP的定位参考信号(Positioning Reference Signal,PRS)的配置。LMF根据DL定位需求以及UE当前的服务小区的位置,确定让UE测量哪些TRP的PRS信号,并将相关PRS通过LPP协议配置给UE。
但在低轨卫星系统中,TRP和卫星是一体的,TRP会随着卫星快速移动的,LMF很难确定定位某个UE所需要的TRP/卫星,很难确定该为UE配置哪些PRS资源。
下面结合附图,通过一些实施例及其应用场景对本公开实施例提供的上行定位方法进行详细地说明。
请参见图2,本公开实施例提供的一种上行定位方法,该方法的执行主体为网络设备,可选地,该网络设备可以是基站,方法包括以下步骤:

具体地,如果LMF知道星历的话,则卫星信息可以只包括卫星ID即可;如果LMF不知道星历的话,则卫星信息可以只包括只有卫星的位置信息即可,当然也不排除两个信息都提供。
在一种可能的实施方式中,网络设备确定多个定位测量时间点具体是由 网络设备自身确定出该多个定位测量时间点,即LMF只是向网络设备发送上行定位请求消息以请求进行上行定位,而具体的定位测量时间点则完全由网络设备自身确定,例如:LMF不提供任何时间信息,基站基于星历等信息确定要执行上行定位的多个时间点以及相应的分配资源。

其中,多个定位测量结果是网络设备在多个定位测量时间点中的每个定位测量时间点,指示与定位测量时间点对应的卫星执行上行定位测量得到的。
本公开实施例中,网络设备接收定位管理功能(Location Management Function,LMF)发送的上行定位请求消息;网络设备确定多个定位测量时间点以及每个定位测量资源对应的卫星信息,并根据这些信息执行上行定位测量得到多个定位测量结果,网络设备向LMF发送给定位测量结果以及每个定位测量结果对应的定位测量时间点和/或卫星信息。由于卫星是处于移动状态的,那么对应多个定位测量时间点,卫星会分别位于多个不同的位置,这样在多个定位测量时间点进行上行定位测量,能够等效于相关技术中的定位方法中的多TRP定位测量,从而通过单星完成终端位置上行定位的方法,在卫星互联网系统中的上行定位。

下面通过多个实施例对本公开提供的上行定位方法进行举例说明:
实施例一:卫星互联网系统中UL定位方法的支持(单星无切换,LMF提供定位时间需求信息)
LMF向基站请求发起某个UE的上行定位请求,请求中包括上文所述的定位测量的时间要求信息(比如:要进行4次测量,间隔不小于5秒,需要在x时刻之前完成)。
基站基于LMF的请求,和或UE当前的服务卫星、服务小区,以及星历等信息,确定用于完成定位测量的具体的多个时间点,以及每个时间点参与定位测量的卫星信息(选定的卫星可以为当前的服务卫星,也可以是即将为UE服务的卫星,取决于基站对定位测量的时间决策)。
在上述指定的定位测量的相关时间点,基站让选定的卫星完成相关UL定位测量,在所有的测量完成后,将结果反馈给LMF。
结果中包含具体的测量结果、每个结果对应的时间信息,以及每个结果对应的卫星信息。
LMF基于gNB反馈的结果,计算出UE的位置。
实施例二:卫星互联网系统中UL定位方法的支持(单星无切换,LMF指示具体的定位时间)
整体过程同实施例一,主要区别在于:
基站基于UE当前的服务卫星、服务小区,结合星历等信息,以及LMF指定的时间信息,确定在每个时间点用于完成UL定位测量卫星信息。
实施例三:卫星互联网系统中UL定位方法的支持(UL定位测量过程中UE发生小区间切换,甚至星间切换,所述切换都是一个基站下的小区间的切换,包括星内,也包括星间。)
如果定位测量的过程中UE发生了小区间切换(同基站,同星或者不同星)
gNB确定具体的定位时间点的机制同实施例一或二,只是不同的时间点下,参与定位过程的小区或者卫星可能发生变化。
在每个时间点gNB指示对应的参与定位测量的卫星完成上行定位测量。在所有的测量均完成后,将每个时间点的测量结果,以及对应的参与上行定位测量的卫星信息反馈给LMF。
LMF根据上述信息计算得出UE位置,完成UL定位过程。
