具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
图1是现有技术中的一种定位终端设备的方法和设备的无线通信系统100架构的示意性框图。如图1所示，该系统100架构包括，终端设备110，无线接入网设备120，接入和移动管理功能网元130(access&mobility function，AMF)，定位管理中心网元140(location management function，LMF)，路口径移动定位中心网元150(gateway mobile location centre，GMLC)。
其中，图1中的终端设备可以用于通过无线空口连接到运营商部署的接入网设备，继而通过接入网设备连接到数据网络；接入网设备主要用于实现无线物理层功能、资源调度和无线资源管理、无线接入控制以及移动性管理等功能；接入和移动性管理功能主要用于终端设备的设备注册、安全认证、移动性管理和位置管理等，定位管理中心主要用于定位终端设备的位置，该LMF位于核心网内部，该LMF必须通过AMF与无线接入网设备通信；该路口径移动定位中心与外部网络连接，接收外部网络的定位需求或者将定位结果发送到外部网络。
在图1的所示的网络中，各功能单元之间可以通过下一代(next generation，NG)接口建立连接实现通信，如：终端设备通过新无线(new radio，NR)接口与接入网设备建立空口连接，用于传输用户面数据和控制面信令；终端设备可以通过NG接口1(简称N1)与AMF建立控制面信令连接；AMF可以通过NLs接口与LMF建立连接；AMF可以通过NLg接口与GLMC建立连接。
应理解，本申请中的网元之间的接口名称仅是示例性的，网元之间的接口还可以是其他名称，本申请对接口的名称不予限。
应理解，该网络架构还可以包括其他功能单元或功能网元，例如，系统100还可以包括用户面功能网元(user plane funtion，UPF)，数据网络(data network，DN)，会话管理功能网元(session management function，SMF)，策略控制功能网元(policy control function，PCF)，应用功能网元(application function，AF)。其中，UPF用于对数据流进行转发、QoS控制、计费统计等；DN可对应于多种不同的业务域，例如IP多媒体子系统(IP multimedia subsystem，IMS)、互联网Internet、互联网协议电视(internet protocol television，IPTV)、其他运营商业务域等，主要用于为终端设备提供多种数据业务服务，其中可以包含例如服务器、路由器、网关等网络设备；AMF用于进行终端设备的接入和移动性管理，接收PCF提供的UE的移动性策略以及网络选择策略并进行策略执行；SMF用于进行PCF提供的会话以及业务流控制策略并进行策略执行；PCF可以根据AF的请求信息、运营商策略、用户签约信息等生成策略与计费控制规则，控制网络行为，并下发策略与计费控制规则至控制面网元；AF主要提供应用侧对网络侧的需求，包括业务流的服务质量需求、用户设备的移动性需求等。
需要说明的是，图1仅为示例性架构图，除图1中所示功能单元之外，该网络架构还可以包括其他功能单元或功能网元，本申请实施例对此不进行限定。
上述的部分网元可以独立工作，也可以组合在一起实现某些控制功能，如：AMF、SMF和PCF可以组合在一起作为管理设备，用于完成终端设备的接入鉴权、安全加密、位置 注册等接入控制和移动性管理功能，以及用户面传输路径的建立、释放和更改等会话管理功能，以及分析一些切片(slice)相关的数据(如拥塞)、终端设备相关的数据的功能，UPF作为网关设备主要完成用户面数据的路由转发等功能，如：负责对终端设备的数据报文过滤、数据传输/转发、速率控制、生成计费信息等。
下面根据图2对现有技术中定位终端设备的方法的过程进行简单描述。
在210中，AMF获取来自不同设备的定位请求，该定位请求用于指示对终端设备定位，该定位请求信息可以来源于三个设备，分别是终端设备发送的定位请求，或外部网络发送的定位请求(该外部网络通过GMLC通知AMF)，或AMF本身的定位需求。
在220中，AMF在获取到不同位置的定位请求后，将定位请求发送给定位中心LMF。
在230中，定位中心LMF与终端设备或者接入网设备进行信令的交互。该信令主要包括LMF向终端设备或者接入网设备定位能力询问，终端设备或者接入网设备定位能力反馈，LMF基于反馈决定使用的定位方法，辅助信息的发送，测量数据的请求，终端设备或者接入网设备在测量了数据后再发送回LMF，LMF基于这些测量数据，计算出UE的位置。这里LMF与UE的信令交互为新空口定位协议(NR Positioning Protocol，NRPP)，LMF与无线接入网设备的信令交互为附加新空口定位协议(NR Positioning Protocol Annex，NRPPa)，该NRPP协议和NRPPa分别对应于LTE中的LTE定位协议(LTE Positioning Protocol，LPP)和附加LTE定位协议(LTE Positioning Protocol Annex，LPPa)。
在240中，该LMF将计算出的终端设备的位置发送给AMF，然后AMF再发回各个发送定位请求信息的设备。
在现有技术中，目前LMF的都在核心网内部，这样的话一旦LMF有定位需求，与终端设备或者无线接入网设备进行NRPP或者NRPPa信令交互中，就需要经过AMF，以NRPP为例，数据的路径为终端设备-无线接入网设备-AMF-LMF，这样需要花费大致2s的延时。不能够满足5G系统下对定位时延的要求。
基于上述问题，本申请提供了一种定位终端设备的方法和设备，接入和移动管理功能网元AMF获取用于定位终端设备的请求，确定使用定位管理中心网元定位所述终端设备，该定位管理中心网元与无线接入网设备具有通信接口，可以直接与无线接入网设备通信，数据可以不经过AMF，直接和无线接入网设备或者终端设备进行传输，则可以减少信令传输时间，降低定位终端设备的延时。
下面是本申请提供地一种定位终端设备的方法和设备的无线通信系统200的架构的示意性框图。如图3所示，该系统300包括终端设备310，无线接入网设备320，分布式定位管理中心网元330(location management function distributed，LMFd)，接入和移动管理功能(access&mobility function，AMF)340，集中式定位管理中心网元350(location management function centralized，LMFc)，路口径移动定位中心360(gateway mobile location centre，GMLC)。该分布式定位管理中心网元LMFd与无线接入网设备之间具有通信接口，该LMFd可以不经过AMF与无线接入网设备进行通信，该系统300中可以包括多个分布式定位管理中心网元LMFd，该分布式定位管理中心网元LMFd下也可以接入多个无线接入网设备，本申请对此并不进行限定。

本申请实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备可以是全球移动通讯(Global System of Mobile communication，GSM)系统或码分多址(Code Division Multiple Access，CDMA)中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional NodeB，eNB或eNodeB)，还可以是云无线接入网络(Cloud Radio Access Network，CRAN)场景下的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等，本申请实施例并不限定。

具体而言，一种方式为该RRC信令中使用一个新的协议，例如UL NRPP Transport/DL NRPP Transport,专门用来传输NRPP的信息。第二种方式是该RCC信令中用现有的某个协议，比如用现有携带的NAS信令的协议，但是加入协议的标志信息，以区分是NAS的协议还是包括NRPP的协议。
应理解，在本申请中，该LMFd与终端设备进行NRPP的信令交互可以包括该LMFd向该终端设备发送下行的NRPP的信令或者该终端设备向该LMFd发送上行的NRPP的信令，该下行的NRPP的信令与上行的NRPP的信令之间没有时间上的先后顺序，并且该下行的NRPP的信令与上行的NRPP的信令可以重复发送。
还应理解，该LMFd与无线接入网设备进行NRPPa的信令交互可以包括该LMFd向该无线接入网设备发送下行的NRPPa的信令或者该无线接入网设备向该LMFd发送上行的NRPP的信令，该下行的NRPPa的信令与上行的NRPPa的信令之间没有时间上的先后顺序，并且该下行的NRPPa的信令与上行的NRPPa的信令可以重复发送。
