目前,存在有一种使用RAT-dependent定位技术来对终端的位置信息进行定位的方法,在该定位过程中,定位管理功能(Location Management Function,LMF)设备通过LCS(location service)获得终端的位置信息,使用RAT-dependent定位技术。在该定位过程中,终端、基站、接入移动管理功能(Access and Mobility Management Function,AMF)设备以及定位管理功能设备这多个设备之间多次交互,增加了定位时延。
其中,LCS即通过NR引入的定位功能来获取UE的位置。接入移动管理功能设备负责注册、连接、可达性、移动性及与安全和访问管理和业务授权。
为了解决上述问题,本公开实施例提供一种定位方法、装置、存储介质及芯片,以减少定位方法中交互的设备,降低定位时延。
下面先介绍本公开实施例的实施环境。
本申请实施例的技术方案可以应用于各种通信系统。该通信系统可以包括4G(the 4th Generation,第四代)通信系统、5G(the 5th Generation,第五代)通信系统、和其他未来的无线通信系统(比如6G)中的一种或多种。该通信系统也可以包括陆上公用移动通信网(Public Land Mobile Network,PLMN)网络、非地面网络(Non-Terrestrial Networks,NTN)通信系统、设备到设备(Device-to-Device,D2D)通信系统、机器到机器(Machine to Machine,M2M)通信系统、物联网(Internet of Things,IoT)通信系统、车联网(Vehicle-to-Everything,V2X)通信系统或者其他通信系统中的一种或多种。
图1是根据一示例性实施例示出的一种通信系统的示意图。如图1所示,该通信系统可以包括终端101和基站102。该通信系统可以用于支持4G(the 4th Generation,第四代)网络接入技术,例如长期演进(Long Term Evolution,LTE)接入技术,或者,5G(the 5th Generation,第五代)网络接入技术,如新型无线入技术(New Radio Access Technology,New RAT),或者,其他未来的无线通信技术。需要说明的是,在该通信系统中,上概述终端和基站的数量均可以为一个或多个,图1所示通信系统的终端和基站的数量仅为一种实施例的适应性举例,本 公开对此不做限定。
图1中的终端可以是一种提供语音或者数据连通性的电子设备,例如也可以称为用户设备(User Equipment,UE),用户单元(Subscriber Unit),移动台(Mobile Station),站台(Station),终端设备等。示例地,该终端可以包括智能手机、智能可穿戴设备、智能音箱、智能平板、无线调制解调器(modem)、无线本地环路(Wireless Local Loop,WLL)台、PDA(Personal Digital Assistant,个人数字助理)、CPE(Customer Premise Equipment,客户终端设备)等。随着无线通信技术的发展,可以接入通信系统、可以与通信系统的基站进行通信,或者通过通信系统与其它物体进行通信的设备都可以是本公开实施例中的终端,例如,智能交通中的终端和汽车、智能家居中的家用设备、智能电网中的电力抄表仪器、电压监测仪器、环境监测仪器、智能安全网络中的视频监测仪器、收款机等。在本公开实施例中,终端可以与基站进行通信。图1中的基站也可以称为接入网设备。
图2是根据一示例性实施例示出的另一种通信系统的示意图。该通信系统针对一种定位服务的场景,在该定位服务中可以应用到本公开实施例的定位方法。下面对应用该通信系统的定位服务进行介绍。
如图2所示,该通信系统可以包括终端201和5G基站202和接入移动管理功能设备203。其中,终端201可以向5G基站202上报自身的位置信息,该位置信息例如可以是终端201基于其具备的GNSS定位的能力,确定的GNSS位置信息。在终端201将自身的位置信息上报到5G基站202之后,5G基站202可以根据终端201的位置信息选择合适的接入移动管理功能设备203,例如,5G基站202可以根据的终端201的位置信息确定终端201所在的国家,然后为终端201选择部署在终端201所在国家的接入移动管理功能设备203;5G基站202还可以根据终端201的位置信息,确定对应的寻呼区域(tracking area),以及tracking area code,并将相关信息发送给接入移动管理功能设备203;5G基站202还可以根据终端201的位置构建CGI(cell global ID),并将cell global ID发送给接入移动管理功能设备203。
然而,在上述过程中,考虑到终端201的位置信息存在被篡改的可能,因此,需要网络能够验证终端201上报的位置信息是否可靠。这种情况下,可以使用本公开实施例的定位方法,使得5G基站202获取到终端201的位置信息,并利用获取到的终端201的位置信息来用于对终端201上报的位置信息进行验证。以使得接入移动管理功能设备203得到终端201的验证结果。

在另一个实施例中,基站在不同位置发送的定位参考信号包括,同一个基站在不同TRP发送的定位参考信号。
在一些情况下,一个基站可以有多个TRP(Transmitting and Receiving Point,传输点),从而,通过同一个基站的不同位置的TRP,便可以在不同发送位置发送定位参考信号。
