针对现有技术的定位方法中,当用户设备的网络环境不佳时,容易出现定位能力下降或定位精度不高的问题,本公开提供了一种定位方法、用户设备及网络设备,通过利用目标UE的临近UE可对目标UE进行辅助定位,使得网络设备可基于辅助定位信息执行对目标UE的定位处理,提升定位精度。
其中,方法和装置是基于同一申请构思的,由于方法和装置解决问题的原理相似,因此装置和方法的实施可以相互参见,重复之处不再赘述。
为了清楚理解本公开的技术方案,首先对现有技术的方案进行详细介绍。
图1是本公开提供的一种网络架构,如图1所示的,该网络架构中包括有终端设备(包括目标UE以及临近UE)以及网络设备。
其中,图1中的终端设备,其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。
本公开实施例涉及的终端设备,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)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。
而本实施例中涉及的网络设备,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),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)节点和分布单元(distributed unit,DU)节点,集中单元和分布单元也可以地理上分开布置。此外,本公开中网络中的网元设备包括但不限于位置管理功能(Location Management Function,简称LMF)。
在如图1所示的通信系统中,一般包括有多个终端设备(如图所示的UE),在本公开中将以各终端设备中的其中一个终端设备(也称目标UE)的定位为例进行说明,而其中的临近UE是指可与目标UE经过临近发现流程通信的终端设备。
在现有定位技术中,目标UE可基于UE自身或第三方应用(应用功能/位置功能客户端,Application Function/Location Services client,简称AF/LCS client)发起定位请求,以使网络侧基于定位请求对其进行定位处理。
其中,通过目标UE自身发起定位请求的定位方式称为MO-LR(Mobile Originated-Location Request)。而通过AF/LCS client发起定位请求的定位方式称为MT-LR(Mobile Terminated-Location Request)。
图2为基于MO-LR的定位方法的流程示意图,如图2所示的,MO-LR的定位方法包括:
步骤201、目标UE进行注册流程在网络中完成注册;
步骤202、目标UE发起MO-LR的服务请求,建立其与接入与移动性管理功能AMF的信令通道;
步骤203、目标UE向接入与移动性管理功能AMF发起MO-LR的定位请求,请求网络对其定位;
步骤204、接入与移动性管理功能AMF选择匹配的位置管理功能LMF,并请求位置管理功能LMF对该目标UE进行定位;
步骤205、位置管理功能LMF对目标UE进行定位,并将定位结果返回给移动性管理功能AMF;
步骤206、移动性管理功能AMF将定位结果发送给移动位置中心网关GMLC;
步骤207、移动位置中心网关GMLC将定位结果直接发送给位置服务客户端LCS client或者通过网络能力开放功能NEF发送给应用功能AF;
步骤207、位置服务客户端/网络能力开放功能LCS client/AF返回响应信息,通过移动位置中心网关GMLC返回给移动性管理功能AMF并进一步返回给目标UE。
其中,在步骤205中,在位置管理功能LMF对目标UE进行定位的过程中,位置管理功能LMF会向目标UE发送自身定位信息的请求,目标UE会在接受请求之后将自身定位信息返回给位置管理功能LMF。位置管理功能LMF会基于该自身定位信息对目标UE进行定位处理,以得到目标UE的定位结果。
图3为基于MT-LR的定位方法的流程示意图,如图3所示的,MT-LR的定位方法包括:
步骤301、目标UE进行注册流程在网络中完成注册;
步骤302、位置服务客户端/网络能力开放功能LCS client/AF发起MT-LR的服务请求,并发送给移动位置中心网关GMLC,以请求网络对目标UE进行定位;
步骤303、GMLC将目标UE的定位请求发送给移动性管理功能AMF;
步骤304、移动性管理功能AMF选择匹配的位置管理功能LMF,请求位置管理功能LMF对该目标UE进行定位;
步骤305、请求位置管理功能LMF对目标UE进行定位,并将定位结果返回给移动性管理功能AMF;
步骤306、移动性管理功能AMF将定位结果发送给移动位置中心网关GMLC;
步骤307、移动位置中心网关GMLC将定位结果直接发送给位置服务客户端LCS client或者通过网络能力开放功能NEF发送给应用功能AF。
其中,在步骤305中,在位置管理功能LMF对目标UE进行定位的过程中,位置管 理功能LMF会向目标UE发送自身定位信息的请求,目标UE会在接受请求之后将自身定位信息返回给位置管理功能LMF。位置管理功能LMF会基于该自身定位信息对目标UE进行定位处理,以得到目标UE的定位结果。
而无论是MO-LR的定位方法还是MT-LR的定位方法,网络侧的位置管理功能LMF均将根据目标UE的自身定位信息对目标UE进行定位处理。
但是,网络侧对目标UE进行定位处理依赖于目标UE周边的网络设备的定位能力,一旦目标UE周边的网络设备的定位能力不足的情况,如出现目标UE的信号强度不佳/信号质量差,和/或,目标UE周边的网络设备数量较少等情况,目标UE返回给位置管理功能LMF的自身定位信息的准确性将大大降低,这会导致位置管理功能LMF对目标UE的进行定位所得到定位结果的精准度将受到极大的影响。
基于这样的技术问题,本公开考虑到可利用临近通信技术ProSe(Proximity Services)来提升目标UE的定位能力。即,通过利用临近UE对目标UE进行辅助定位测量,得到目标UE的辅助定位信息。网络侧将根据获取的目标UE的自身定位信息结合目标UE的辅助定位信息进行定位处理,得到目标UE的定位结果。
具体来说,在ProSe中,UE与UE之间可通过PC5接口进行的Layer 2/Layer 3通信,并且,UE与网络之间可通过Uu接口进行的Layer 2/Layer 3通信。基于此,当目标UE的定位能力不佳时,可利用ProSe技术确定出目标UE的临近UE以作为中继UE(relay UE),利用该中继UE(临近UE)的中继通信以提升目标UE的定位能力。
也就是说,通过将定位服务技术和ProSe技术相结合,通过使临近UE对目标UE进行辅助定位,并将辅助定位信息发送给网络,从而使得网络侧能够结合辅助定位信息更好对目标UE进行定位,得到更高精度的定位结果。
以下将参照附图并结合如上提供的各步骤来具体描述本公开的实施例。
实施例一
图4是本公开提供的一种定位方法的流程示意图,结合前述图1所示网络设备的结构和功能步骤,如图4所示的,本实施例的执行主体为图1所示结构中的用户设备,本实施例提供的方法将应用于目标UE。
结合图4,本实施例提供的定位方法至少包括以下几个步骤:
步骤401、向位置管理功能LMF发送定位服务请求;
步骤402、接收位置管理功能LMF发送的第一辅助请求消息;
步骤403、根据第一辅助请求消息请求临近UE对目标UE进行辅助定位测量,得到临近UE返回的辅助定位信息;
步骤404、向位置管理功能LMF发送第一响应消息,其中,第一响应消息包括目标UE的自身定位信息和辅助定位信息;
步骤405、获得定位结果;其中,定位结果是位置管理功能LMF根据第一响应消 息对目标UE进行定位处理获得的。
需要明确的是,本公开实施例一是针对于基于MO-LR的定位方法进行的改进。
在本公开的步骤401中,目标UE会基于用户使用需求生成定位服务请求,并通过网络侧的接入与移动性管理功能AMF,将该定位服务请求发送至位置管理功能LMF,而位置管理功能LMF将根据该定位服务请求触发本公开提供的定位方法对目标UE的定位。
其中,在本公开实施例一提供的定位方法中,与现有技术不同的是,目标UE是支持辅助定位功能的。其中,如步骤402所述的,当目标UE发出定位服务请求后,目标UE会接收到网络侧的位置管理功能LMF发送的第一辅助请求消息。其中,该第一辅助请求消息是位置管理功能LMF在确定触发辅助定位进程的情况下发出的,而位置管理功能LMF确定触发对所述目标UE的辅助定位进程的判定方式可参见实施例二的相关描述,本实施例一中不对此进行过多赘述。
在步骤403中,目标UE接收到第一辅助请求消息之后,目标UE将向该目标UE的临近UE发送辅助定位测量的请求,以请求临近UE对目标UE进行辅助定位测量,得到临近UE返回的辅助定位信息。
其中,辅助定位信息包括:临近UE的位置信息和/或临近UE与目标UE之间的相对位置信息。
示例性的,临近UE的位置信息包括:临近UE的绝对位置,和/或,临近UE的相对位置;其中,临近UE的绝对位置可以但不局限于是例如经纬度,临近UE的相对位置,临近UE相对于固定坐标的距离。
其中进一步的,为了提升定位精度,辅助定位信息中还包括:临近UE与目标UE之间的相对位置信息。示例性的,临近UE与目标UE之间的相对位置信息包括距离,方向,方位角,RTT,信号强度变化等信息。
此外,再进一步的,辅助定位信息中还包括临近UE的未来轨迹,临近UE的速度等。
而上述的临近UE则是指目标UE经过临近发现流程确定出的同样具有支持临近辅助定位功能的UE。具体的,临近发现流程则是基于前述提及的ProSe技术实时进行的通信过程,其包括但不限于通过协商或广播以建立通信通道,实现UE之间的业务交互和信息交互。
在可选实施方式中,临近发现流程可为周期性触发的流程,即目标UE可按照预定周期重复执行临近发现流程以确定目标UE当前所处环境的临近UE。对于每一次临近发现流程来说,目标UE可先发现其周边的UE并取得通信。随后,目标UE将确定其周边的UE是否支持临近辅助定位。其中,目标UE通过判断周边的UE发送信令或广播消息中是否携带有“支持临近辅助定位”的参数来确定该周边UE是否支持临近辅助定位功能。
即,当目标UE发现周边的UE发送信令或广播消息中携带有“支持临近辅助定位” 的参数时,目标UE确定该周边的UE支持临近辅助定位功能,此时,该周边的UE可作为目标UE的临近UE;反之,当目标UE发现周边的UE发送信令或广播消息中未携带有“支持临近辅助定位”的参数时,目标UE确定该周边的UE不支持临近辅助定位功能,此时,该周边的UE不可作为目标UE的临近UE。
在步骤404中,目标UE将在获取辅助定位信息之后向位置管理功能LMF发送第一响应消息,其中,所述第一响应消息包括目标UE的自身定位信息和所述辅助定位信息。
其中,目标UE的自身定位信息是指目标UE对自身位置进行定位测量获得的信息,示例性的,目标UE的自身定位信息包括:目标UE的绝对位置,和/或,目标UE的相对位置;其中,目标UE的绝对位置可例如经纬度,目标UE的相对位置可例如目标UE相对于固定坐标的距离;此外,该自身定位信息中还可携带包括目标UE当前所处网络的网络环境的信息,如信号质量、信号强度、周边基站数量等等。需要明确的是,该自身定位信息的具体获取方式与现有技术类似,在本公开中对其获取方式和具体构成不进行限制。
当目标UE得到自身定位信息之后,会将该自身定位信息和前述得到的辅助定位信息打包得到第一响应消息,并将该第一响应消息发送至位置管理功能LMF。
步骤405中,目标UE从位置管理功能LMF获得定位结果;其中,所述定位结果是所述位置管理功能LMF根据所述第一响应消息对所述目标UE进行定位处理获得的。其中,LMF根据目标UE的自身定位信息和辅助定位信息确定其定位结果的具体实现过程与基站的辅助定位实现过程类似,在本公开中不做更多赘述。
至此,目标UE得到定位结果,与现有技术相比,该定位结果的定位精度明显提升。
在上述实施方式的基础上,目标UE的位置发生变动或网络环境发生变动均会引起其临近UE出现变化,目标UE发送给位置管理功能LMF的辅助定位信息可能不满足辅助定位条件。此时,目标UE将接收所述位置管理功能LMF发送的重发消息,并根据该重发消息重新执行临近发现流程,以将新的临近UE返回的新的辅助定位信息发送至位置管理功能LMF。
即,目标UE接收所述位置管理功能LMF发送的重发消息;其中,所述重发消息是所述位置管理功能LMF在确定所述辅助定位信息不满足辅助定位条件时发送的;根据所述重发消息重新执行临近发现流程以确定新的临近UE,请求所述新的临近UE对目标UE进行辅助定位测量,得到所述新的临近UE返回的新的辅助定位信息;向所述位置管理功能LMF发送重发响应信息,其中,所述重发响应信息中包括所述新的辅助定位信息以及所述目标UE的自身定位信息。
示例性地,定位请求中可能要求对目标UE进行周期性定位或延迟定位,或者目标UE过早的执行了临近发现过程,则可能造成以下情况:后期定位时,目标UE的临近UE会发生变化,那么目标UE返回给LMF的辅助定位信息可能会不符合LMF之前的要 求。
示例性的,LMF判断目标UE上报的辅助定位信息不满足辅助定位条件,辅助定位信息不满足辅助定位条件具体可以是例如临近UE数量太少,或临近UE的信号太差等,则重复执行辅助定位信息获取以及上报步骤。
在上述实施方式的基础上,本公开的目标UE还需要向网络侧表明自身支持临近辅助定位的功能,以便于位置管理功能LMF可基于目标UE的定位服务请求执行基于辅助定位的定位处理。
其中,目标UE可通过多种方式向网络表明自身具有该临近辅助定位的功能:
在第一种情况中,目标UE可通过在注册流程中向网络侧表明自身支持临近辅助定位功能。即,目标UE向网络侧发送注册信息,所述注册信息包括第一临近辅助定位参数,所述第一临近辅助定位参数用于表征目标UE支持临近辅助定位功能。
具体来说,在目标UE入网后,会先执行注册流程,其注册流程包括但不限于:初始注册、移动性注册、周期性注册、紧急注册。在注册过程中,目标UE会将第一临近辅助定位参数写入注册信息中,以告知包括位置管理功能LMF在内的网络设备,该目标UE支持临近辅助定位功能。进一步的,注册信息中还包括有目标UE的应用层标识,该应用层标识为UE在临近发现/通信过程中使用的应用层标识。
在第二种情况中,目标UE通过定位服务请求向网络侧表明自身支持临近辅助定位功能。即,定位服务请求中携带第二临近辅助定位参数,所述第二临近辅助定位参数用于表征目标UE支持临近辅助定位功能。
具体的,目标UE可在其发起的定位服务请求中写入“支持临近辅助定位”参数(即,第二临近辅助定位参数)。当网络侧的位置管理功能LMF在获取到该定位服务请求之后,将根据其中的第二临近辅助定位参数确定出目标UE支持临近辅助定位功能。
在第三种情况中,目标UE还可通过用户签约信息告知网络侧自身支持临近辅助定位功能。具体来说,
具体的,用户签约信息是指目标UE在入网时与网络供应商在签约时所生成的信息,其一般包括但不限于用户身份信息、用户开设业务需求等等。一般的,该用户签约信息是存储在网络侧的统一数据管理服务器UDM中的。
一方面,在目标UE入网时,目标UE可通过接入与移动性管理功能AMF在其对应的上下文中写入第二临近辅助定位参数。
另一方面,目标UE还可通过调用网络能力开放功能NEF将第二临近辅助定位参数写入所述用户签约信息。具体的,目标UE的LCS client/AF还可通过调用网络能力开放功能NEF的Nnef_ParameterProvision_Ceate/Update/Delete等的服务调用统一数 据管理服务器UDM的Nudm_ParameterProvision_Ceate/Update/Delete服务,以对UDM中存储的目标UE的用户签约信息进行更新,并在用户签约信息中写入第二临近辅助定位参数。
位置管理功能LMF可通过接入与移动性管理功能AMF查询统一数据管理服务器UDM中的用户签约信息,并得到用户签约信息携带有第二临近辅助定位参数确定出目标UE具备临近辅助定位能力。
上述提供的在多种信息中携带用于表示“目标UE支持临近辅助定位功能”的相关参数的方式可同时存在,即可能情况中,目标UE可同时在不同流程的信息中分别携带有第一临近辅助定位参数、第二临近辅助定位参数以及第三临近辅助定位参数。而对于位置管理功能LMF来说,其在获取到任一临近辅助定位参数时,均可确定出目标UE支持临近辅助定位功能。
本公开实施例一提供的定位方法,结合临近通信技术实现对用户设备的定位,其中,目标UE向位置管理功能LMF发送定位服务请求;接收位置管理功能LMF发送的第一辅助请求消息;根据所述第一辅助请求消息请求临近UE对目标UE进行辅助定位测量,得到所述临近UE返回的辅助定位信息;向所述位置管理功能LMF发送第一响应消息,其中,所述第一响应消息包括所述目标UE的自身定位信息和所述辅助定位信息;获得定位结果;其中,所述定位结果是所述位置管理功能LMF根据所述第一响应消息对所述目标UE进行定位处理获得的。与现有的基于MO-LR或MT-LR的定位技术相比,本公开实施例一提供的定位技术在定位处理时将结合辅助定位信息,其定位能力更强,精度更高。
实施例二
图5是本公开提供的另一种定位方法的流程示意图,结合前述图1所示网络设备的结构和功能步骤,如图5所示的,本实施例的执行主体为图1所示结构中的网络设备,本实施例提供的方法将应用于网络侧的位置管理功能LMF。
结合图5,本实施例提供的定位方法至少包括以下几个步骤:
步骤501、接收对目标UE进行定位的定位服务请求。
步骤502、若确定所述目标UE支持临近辅助定位功能且确定触发对所述目标UE的辅助定位进程,则获得所述目标UE的自身定位信息和辅助定位信息;其中,所述辅助定位信息是临近UE对所述目标UE进行辅助定位测量所获得的信息。
步骤503、根据所述目标UE的自身定位信息和辅助定位信息对所述目标UE进行定位处理,得到定位结果。
需要明确的是,在本公开中,而无论是针对MO-LR的定位方法还是MT-LR的定位方法,均可采用本公开实施例二所提供的定位方法以进行对目标UE进行定位。
在本公开实施例中,位置管理功能LMF在执行对目标UE的定位过程中利用了 ProSe技术以提升目标UE的定位能力和定位精度。
在步骤501中,网络侧的位置管理功能LMF将接收到对目标UE进行定位的定位服务请求。
在本实施例中,定位服务请求可为基于MO-LR发起的请求,即该定位服务请求可为目标UE通过接入与移动性管理功能AMF发起定位服务请求;在定位服务请求还可为基于MT-LR发起的请求,即,位置服务客户端/网络能力开放功能LCS client/AF发起MT-LR的定位服务请求。
在本实施方式中,位置管理功能LMF接收到定位服务请求之后,将对目标UE是否支持临近辅助定位功能进行判定,还会对是否要触发辅助定位进程进行判定。
如步骤502和503所述的,位置管理功能LMF会在确定目标UE支持临近辅助定位功能且确定触发对所述目标UE的辅助定位进程的情况下,获取到目标UE的自身定位信息和辅助定位信息,并基于该目标UE的自身定位信息和辅助定位信息确定出目标UE的定位结果,以返回给目标UE。
在可选实施方式中,位置管理功能LMF在获取到辅助定位信息之后,还会对辅助定位信息是否满足辅助定位条件进行判定,以保证仅在辅助定位信息满足辅助定位条件的情况下执行定位处理。
示例性的,辅助定位信息不满足辅助定位条件可如辅助定位信息来自N个临近UE,而N小于阈值;还可如,提供辅助定位信息的临近UE的信号质量较差等。
而一旦确定辅助定位信息不满足辅助定位条件,位置管理功能LMF将会要求目标UE重新进行临近发现流程,以重新确定临近UE并重新获得目标UE的辅助定位信息。
也就是说,若位置管理功能LMF确定所述辅助定位信息不满足辅助定位条件,则向所述目标UE发送重发消息,所述重发消息用于请求所述目标UE重新执行临近发现流程。
相应的,当目标UE获取重发消息之后,可如之前实施例所述的,重新执行临近发现流程以确定新的临近UE,并将新的临近UE对目标UE进行辅助定位测量所得到新的辅助定位信息通过重发响应信息返回给位置管理功能LMF。
通过这样的方式,能够有效保证辅助定位信息的信息质量,有利于进一步提升定位结果的精度。
在上述实施方式的基础上,本实施例二中提供了两种不同的获取到目标UE的自身定位信息和辅助定位信息的实现方式。
图6为本公开提供的定位方法的第一信令示意图,结合图6所示的,在方式一中,位置管理功能LMF可直接要求目标UE返回自身定位信息和辅助定位信息:
步骤5021a、向所述目标UE发送第一辅助请求消息,所述第一辅助请求消息用于请求所述目标UE上报辅助定位信息;
步骤5022a、接收所述目标UE返回的第一响应信息,所述响应信息包括所述目标UE的自身定位信息和所述辅助定位信息。
如步骤5021a-5022a所述的,位置管理功能LMF可通过第一辅助请求消息,要求目标UE直接上报辅助定位信息。而相应的,目标UE在获取到该第一辅助请求消息之后,将通过与临近UE的交互,得到辅助定位信息;同时,还通过自身定位测量得到自身定位信息。随后,目标UE会将该两种信息同时发送给位置管理功能LMF,以供位置管理功能LMF进行定位处理。
图7为本公开提供的一种定位方法的第二信令示意图,结合图7所示的,在方式二中,位置管理功能LMF可要求目标UE返回临近UE的UE信息,并通过UE信息要求临近UE直接返回目标UE的辅助定位信息:
步骤5021b、向目标UE发送第二辅助请求消息,所述第二辅助请求消息用于请求所述目标UE上报所述临近UE的标识信息;
步骤5022b、接收所述目标UE返回的第二响应信息,所述第二响应信息包括所述目标UE的自身定位信息和所述临近UE的标识信息。
步骤5023b、根据所述标识信息向所述临近UE发送第三辅助请求消息,所述第三辅助请求消息用于请求所述临近UE对所述目标UE进行辅助定位测量;
步骤5024b、接收所述临近UE返回的所述目标UE的辅助定位信息。
如步骤5021b-5024b所述的,位置管理功能LMF可通过第二辅助请求消息,要求目标UE直接上报其当前临近UE的标识信息。而目标UE在获取到第二辅助请求消息时,其一方面可将最近一次执行临近发现流程确定出的临近UE的标识信息返回给位置管理功能LMF,另一方面还对自身定位测量得到自身定位信息同步返回给位置管理功能LMF。而当位置管理功能LMF得到临近UE的标识信息之后,可通过临近UE的标识信息与临近UE建立通信,并要求临近UE对目标UE进行辅助定位测量,从而得到目标UE的辅助定位信息,以进行定位处理。
特别的,在本公开实施例中,还提供了位置管理功能LMF如何确定目标UE支持临近辅助定位功能的方式。位置管理功能LMF可通过获取目标UE在不同通信过程中产生的信息来判断该目标UE是否支持临近辅助定位功能。
在第一种情况中,位置管理功能LMF根据目标UE的注册信息,确定所述目标UE支持临近辅助定位功能。
具体的,目标UE在入网后会将注册信息发送至网络侧的各网络设备。而位置管理功能LMF可在获取到该注册信息后,将对该注册信息中是否存在临近辅助定位参数进行判定。
其中,当位置管理功能LMF确定出该注册信息中存在临近辅助定位参数时,位置 管理功能LMF将确定出目标UE支持临近辅助定位功能;反之,当位置管理功能LMF确定出该注册信息中不存在临近辅助定位参数时,位置管理功能LMF将确定出目标UE可能不支持临近辅助定位功能。
在第二种情况中,位置管理功能LMF根据所述定位服务请求,确定所述目标UE支持临近辅助定位功能。
具体的,位置管理功能LMF可在获取到该定位服务请求后,将对该定位服务请求中是否存在临近辅助定位参数进行判定。
如前所述的,定位服务请求可为基于MO-LR发起的请求,也可为基于MT-LR发起的请求。
其中,当定位服务请求是基于MO-LR时,目标UE在发起定位服务请求时会将“支持临近辅助定位”参数写入请求中,以由接入与移动性管理功能AMF将定位服务请求发送至位置管理功能LMF。
当定位服务请求是基于MT-LR时,AF/LCS Client在发起定位服务请求时,会将目标UE的UE标识以及“支持临近辅助定位”参数写入请求,以依次通过移动位置中心网关GMLC和接入与移动性管理功能AMF,将该请求发送至位置管理功能LMF。
基于此,当位置管理功能LMF获取到定位服务请求之后,通过判断该定位服务请求中存在临近辅助定位参数即可确定目标UE是否支持临近辅助定位功能。即,当位置管理功能LMF确定出该定位服务请求中存在临近辅助定位参数时,位置管理功能LMF将确定出目标UE支持临近辅助定位功能;反之,当位置管理功能LMF确定出该定位服务请求中不存在临近辅助定位参数时,位置管理功能LMF将确定出目标UE可能不支持临近辅助定位功能。
第三种情况,位置管理功能LMF根据所述目标UE的用户签约信息,确定所述目标UE支持临近辅助定位功能。
具体的,位置管理功能LMF在确定接收到定位服务请求之后,还将从查询统一数据管理服务器UDM中读取目标UE的用户签约信息。
其中,当位置管理功能LMF确定出该用户签约信息中存在临近辅助定位参数时,位置管理功能LMF将确定出目标UE支持临近辅助定位功能;反之,当位置管理功能LMF确定出该用户签约信息中不存在临近辅助定位参数时,位置管理功能LMF将确定出目标UE可能不支持临近辅助定位功能。
需要明确的是,对于位置管理功能LMF来说,当其在任意一种情况下确定目标UE的信息存在临近辅助定位参数时,均可确定出目标UE支持临近辅助定位功能。
在上述实施方式的基础上,本公开实施例还提供了位置管理功能LMF确定触发目 标UE的辅助定位进程的具体方式。
即,若确定当前网络符合如下条件中的至少一个条件,则触发对所述目标UE的辅助定位进程;其中,所述至少一个条件包括:所述目标UE的当前网络环境符合辅助定位的网络环境;所述定位服务请求中携带有辅助定位处理的定位需求信息。
具体的,目标UE的当前网络环境具体可包括:目标UE周围可测量基站的数量、目标UE的信号质量等。网络侧可对目标UE的当前网络环境进行感知,并在发现目标UE周围可测量基站的数量较少,或者,目标UE的信号质量较差的情况下,触发对目标UE的辅助定位进程。
此外,当定位服务请求中携带有辅助定位处理的定位需求信息时,也将触发对目标UE的辅助定位进程。具体的,定位需求信息是指对目标UE触发定位服务的需求。在一些实际业务中,对于目标UE的定位结果的精度要求较高,此时,定位服务请求中所描述的定位需求信息会写入相应参数以表征网络侧需要对目标UE进行基于辅助定位的定位处理。
在上述实施方式的基础上,位置管理功能LMF也同时支持现有技术中的定位方法。一般的,若位置管理功能LMF确定目标UE符合如下条件时,将采用现有的定位方法对目标UE进行定位。
即,若确定所述目标UE符合以下条件之一向目标UE发送自身定位信息的上报请求;根据所述目标UE返回的所述自身定位信息对所述目标UE进行定位处理,得到所述目标UE的定位结果;其中所述条件包括:所述目标UE不支持临近辅助定位功能;确定不触发对所述目标UE的辅助定位进程;当前网络设备不支持临近辅助定位功能。
其中,对于目标UE不支持临近辅助定位功能和确定不触发对所述目标UE的辅助定位进程的确定可参见前述实施方式,本实施方式对此不进行赘述。而对于确定当前网络设备不支持临近辅助定位功能的实现方式,则是指位置管理功能LMF本身不支持基于辅助定位信息的定位运算处理。
在图6的基础上,图8为本公开提供的定位方法的第三信令示意图,该图8所示的第三信令示意图为图6所示流程的完整信令流程,该流程包括:
S1、目标UE进行注册流程在网络中完成注册;执行S2a,或者,执行S21b。

S4、位置管理功能LMF向目标UE发送第一辅助请求消息,第一辅助请求消息用于请求目标UE上报辅助定位信息。

S6、目标UE将向临近UE发送辅助定位测量的请求,以请求临近UE对目标UE进行辅助定位测量。
S7、目标UE得到临近UE返回的辅助定位信息。
S8、目标UE向位置管理功能LMF发送第一响应消息,该第一响应消息中包括自身定位信息和辅助定位信息。
S9、位置管理功能LMF根据目标UE的自身定位信息和辅助定位信息对目标UE进行定位处理,得到定位结果,并将该定位结果发送至接入与移动性管理功能AMF;根据需求,执行S10a,和/或,执行S10b。
S10a、接入与移动性管理功能AMF将定位结果返回给目标UE。
S10b、接入与移动性管理功能AMF通过移动位置中心网关GMLC,将定位结果发送给位置服务客户端LCS client或者通过网络能力开放功能NEF发送给应用功能AF。
上述的S4-S9的过程与现有技术(参见图2或图3)不同,其余步骤与现有技术类似。在该过程中,位置管理功能LMF可通过第一辅助请求消息,要求目标UE直接上报辅助定位信息。而相应的,目标UE在获取到该第一辅助请求消息之后,将通过与临近UE的交互,得到辅助定位信息;同时,还通过自身定位测量得到自身定位信息。随后,目标UE会将该两种信息同时发送给位置管理功能LMF,以供位置管理功能LMF进行定位处理。
在图7的基础上,图9为本公开提供的定位方法的第四信令示意图,该图9所示的第四信令示意图为图7所示流程的完整信令流程,该流程包括:
S1、目标UE进行注册流程在网络中完成注册;执行S2a,或者,执行S21b。
S2a、目标UE向接入与移动性管理功能AMF发起MO-LR的服务请求,请求网络侧对其定位;执行S3。
S21b、位置服务客户端/网络能力开放功能LCS client/AF向移动位置中心网关GMLC发起MT-LR的服务请求,以请求网络侧对目标UE进行定位;
S22b、GMLC向接入与移动性管理功能AMF发送目标UE的定位请求;执行S3。
S3、接入与移动性管理功能AMF选择匹配的位置管理功能LMF,将定位服务请求发送至位置管理功能LMF,以请求LMF对该目标UE进行定位。
若确定目标UE支持临近辅助定位功能且确定触发对目标UE的辅助定位进程,执行S4。
S4、位置管理功能LMF向目标UE发送第二辅助请求消息,第二辅助请求消息用于请求目标UE上报临近UE的标识信息。
S5、目标UE执行临近发现流程,以确定临近UE。其中,该S5可早于S2a或S21b,本公开对其触发时机不进行限制。
S6、目标UE向位置管理功能LMF发送第二响应信息,该第二响应消息中包括自身定位信息和临近UE的标识信息。

S8、位置管理功能LMF得到临近UE返回的辅助定位信息。

S10a、接入与移动性管理功能AMF将定位结果返回给目标UE。
S10b、接入与移动性管理功能AMF通过移动位置中心网关GMLC,将定位结果发送给位置服务客户端LCS client或者通过网络能力开放功能NEF发送给应用功能AF。
上述的S4-S9的过程与现有技术(参见图2或图3)不同,其余步骤与现有技术类似。位置管理功能LMF可通过第二辅助请求消息,要求目标UE直接上报其当前临近UE的标识信息。而目标UE在获取到第二辅助请求消息时,其一方面可将最近一次执行临近发现流程确定出的临近UE的标识信息返回给位置管理功能LMF,另一方面还对自身定位测量得到自身定位信息同步返回给位置管理功能LMF。而当位置管理功能LMF得到临近UE的标识信息之后,可通过临近UE的标识信息与临近UE建立通信,并要求临近UE对目标UE进行辅助定位测量,从而得到目标UE的辅助定位信息,以进行定位处理。
如图8和图9所示的方案中,由于网络通过将LCS技术和ProSe相结合,通过使临近UE可对目标UE进行辅助定位,并将辅助定位信息发送给网络侧,从而使得网络能更好的目标UE进行定位,如实现更高的定位精度。
本公开提供的定位方法,结合临近通信技术实现对用户设备的定位,其中,网络设备接收对目标UE的定位服务请求;若确定目标UE支持临近辅助定位功能且网络设备确定触发对目标UE的辅助定位进程,则网络设备获得目标UE的自身定位信息和辅助定位信息,并根据目标UE的自身定位信息和辅助定位信息对目标UE进行定位处理,得到定位结果;其中,辅助定位信息是临近UE对目标UE进行辅助定位测量所获得的信息。与现有技术相比,本公开提供的定位技术在定位处理时将结合辅助定位信息, 其定位能力更强,精度更高。
