终端设备可以是一种具有无线收发功能的设备，也可以称之为终端(terminal)。终端设备可以指各种形式的用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)、接入终端设备、车载终端设备、工业控制终端设备、UE单元、UE站、移动站、远方站、远程终端设备、移动设备、UE终端设备、无线通信设备、UE代理或UE装置等。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、可穿戴设备，未来通信***中的终端设备等。终端设备可以是固定的或者移动的。在一些实施例中，终端设备还可以是具有收发功能的装置，例如芯片模组。其中，芯片模组可以包括芯片，还可以包括其它分立器件。本申请的实施例对终端设备所采用的具体技术和具体设备形态不作限定。
网络设备可以是一种为终端设备提供无线通信功能的设备，也可称为网络设备或无线接入网(radio access network，RAN)设备等。网络设备可包括但不限于：演进型节点B(evolved node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、网络设备控制器(base station controller，BSC)、网络设备收发台(base transceiver station，BTS)、家庭网络设备(例如，home evolved Node B，或home Node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WIFI)***中的接入点(access point，AP)、无线中继节点、无线回传节点、收发节点(transmission and reception point，TRP)、传输点(transmission point，TP)等；还可以为5G、6G甚至7G***中使用的设备，如NR***中的gNB，或传输点(TRP或TP)。在一些实施例中，网络设备还可以为具有为终端设备提供无线通信功能的装置，例如芯片模组。示例的，芯片模组可以包括芯片，还可以包括其它分立器件。本申请的实施例对网络设备所采用的具体技术和具体设备形态不作限定。

1.Uu口定位
Uu口定位指通过Uu口(或称为蜂窝网通信接口)发送的终端设备与网络设备之间的定位参考信号实现的定位。Uu口定位还可以描述为主定位、主链路定位或Uu链路定位等。终端设备与网络设备之间的定位参考信号可以是信道探测参考信号(SRS)和/或定位参考信号(PRS)。
Uu口定位可分为上行链路(uplink，UL)定位和下行链路(downlink，DL)定位。Uu口定位的定位请求类型主要分为以下三种：移动初始位置请求(mobile originated location request,MO-LR)，移动终结位置请求(mobile terminated location request，MT-LR)和网络 诱发位置请求(network induced location request,NI-LR)。其中，MO-LR是终端设备向当前服务公用陆地移动通信网络(public land mobile network，PLMN)发送的位置请求；MT-LR是定位服务(location service，LCS)客户端、内部或外部应用功能(application function,AF)向当前服务PLMN发起的位置请求；NI-LR是终端设备的服务AMF为监管业务发起的位置请求，如终端设备的紧急呼叫。
(1)Uu口定位流程
以MO-LR为例，请参阅图2，图2为Uu口定位中MO-LR的定位流程示意图。如图2中所示，该Uu口定位***中包括终端设备(UE)，接入网设备和核心网设备三部分，其中，核心网设备包括接入和移动性管理功能(AMF)设备和定位管理功能(LMF)设备。如图2所示的定位流程包括但不限于以下步骤：
S201，UE触发业务请求以建立和AMF的信令连接。
当UE处于连接管理空闲(connection management–idle，CM-IDLE)态时，UE可触发业务请求来建立和AMF的信令连接。
S202，UE向AMF发送MO-LR。
其中，MO-LR可携带在UL非接入层(non-access-stratum，NAS)传输(transport)消息中。UE发送的NAS消息可直接发送至AMF处。可选的，MO-LR请求信息中可包括LPP定位消息，LPP定位消息可包括定位请求类型，如请求估计UE的位置信息，或请求估计UE的位置信息并将UE的位置信息发送至LCS客户端或AF，或者，请求定位辅助数据等。在MO-LR中包括请求估计UE的位置信息，或包括请求估计UE的位置信息并发送给LCS客户端或者AF的情况下，MO-LR还可携带定位的服务质量(quality of service,QoS)要求信息。可选的，QoS要求信息可包括定位精度、定位响应时间、LCS QoS等级等信息中的一项或多项。
S203，AMF选择LMF，并向LMF发起定位请求信息。
AMF根据本地配置信息或者其他信息选择合适的LMF，示例性的，其他信息可以是QoS需求信息。可选的，该定位请求信息可以是确定位置请求(nlmf_location_determinelocation request)消息。该定位请求信息中可包括LCS相关标识信息、当前服务小区标识、UE类型、UE定位需求信息。其中，UE定位需求信息用于指示UE是否进行定位估计，和/或，指示UE是否请求定位辅助信息等。
S204，LMF发起UE定位过程(UE positioning)。
