具体实施方式
基于位置的服务(location based services，LBS)，是利用各类型的定位技术来获取终端设备当前所在位置，然后通过移动互联网向终端设备提供信息资源和基础服务。LBS服务中融合了移动通讯、互联网络、空间定位、位置信息、大数据等多种信息技术，利用移动互联网络服务平台进行数据更新和交互，使用户可以通过空间定位来获取相应的服务。
目前，定位方法有很多，包括但不限于：全球定位系统(global positioning system，GPS)定位、接入网设备定位、无线保真(wireless fidelity，WiFi)辅助定位、辅助全球定位系统(assisted global positioning system，A-GPS)定位、北斗定位等。
其中，接入网设备定位需要使用部署的网络架构，如第四代(4th generation，4G)网络或第五代(5th generation，5G)网络等。为便于说明，本申请实施例以图1所示的5G 网络架构为例进行说明。5G网络架构中包括终端设备、接入网设备(也称为无线接入网(radio access network，RAN)设备)和核心网(core network)三部分。
其中，终端设备是用于实现无线通信功能的设备，如手机、物联网终端设备等，主要指被定位的对象，负责测量，收集定位相关数据。
接入网设备除了用于实现无线接入有关的功能之外，还收集定位数据(如终端设备的位置信息)，并将定位数据上报至核心网，由核心网基于定位数据确定终端设备的位置。接入网设备包括但不限于下一代基站(g nodeB，gNB)、演进型节点B(evolved node B，eNB)等。
核心网内与定位相关的网元主要包括：接入和移动管理功能(access and mobility management function，AMF)网元、位置管理功能(location management function，LMF)网元、网络能力开放功能(network exposure function，NEF)网元、网关移动定位中心(gateway mobile location center，GMLC)网元、统一数据管理(unified data management，UDM)网元、应用功能(application function，AF)网元。
AMF网元主要负责移动网络中的移动性管理，如用户位置更新、用户注册网络、用户切换等。
UDM网元用于存储用户数据，如签约信息、鉴权/授权信息。
LMF网元主要负责定位业务时进行定位请求管理，定位资源调配以及确定终端设备的位置。
GMLC网元主要负责定位业务的定位请求处理，并为定位业务选择合适的AMF网元。
AF网元，可用于向核心网发起定位业务，并从核心网获取到终端设备的位置。
本申请实施例中的会话管理网元、移动性管理网元、位置管理网元、应用功能网元分别可以是图1中的SMF、AMF、LMF、AF，也可以是未来通信如第六代(6th generation，6G)网络中具有上述SMF、AMF、LMF、AF的功能的网元，本申请对此不限定。为方便说明，本申请以会话管理网元、移动性管理网元、位置管理网元、应用功能网元分别为上述SMF、AMF、LMF、AF为例进行说明。
为实现快速定位终端设备的位置，本申请实施例提供一种定位方法，该方法基于控制面的消息交互实现定位。LMF通过AMF与接入网设备交互，从接入网设备获取到用于定位的信息(比如终端设备的位置信息)，进而LMF基于获取到的用于定位的信息确定终端设备的位置。该方法中，接入网设备与LMF之间的消息需要由AMF转发，而AMF是控制面网元，并且一般部署的位置距离LMF较远，导致接入网设备与LMF之间的消息收发路径较长，最终导致完成一次终端设备的定位需要花费较长的时间。
为此，本申请实施例还提供一种定位方法，该方法通过用户面实现终端设备的定位。
参考图2，为本申请实施例提供的一种定位方法示意图。该方法包括以下步骤：
步骤201，LMF通过会话向终端设备发送第一消息。相应地，终端设备通过该会话收到该第一消息。
该第一消息用于请求终端设备的位置信息。该第一消息例如是定位消息(position message)。
会话是用于为终端设备与数据网络(DN)之间提供数据连通性，终端设备的上下行数 据需要通过会话来承载。该会话例如可以是协议数据单元(protocol data unit，PDU)会话，PDU的类型可以是网络之间的互联协议(internet protocol，IP)，或者以太网(Ethernet)，或者无结构类型。
需要注意的是，第一消息也可以替换为一个容器(container)，该容器包括用于请求终端设备的位置信息的信息。
步骤202，终端设备通过该会话向接入网设备发送第一消息。相应地，接入网设备通过该会话收到该第一消息。
可选的，第一消息采用LMF与接入网设备之间的定位协议。可选的，该定位协议为新无线位置协议A(New Radio Positioning Protocol A，NRPPa)。可选的，当该定位协议是NRPPa，则该第一消息可以替换为NRPPa容器。当第一消息采用LMF与接入网设备之间的定位协议，则终端设备从LMF收到第一消息后，不解析该第一消息，而是将该第一消息透传给接入网设备，可以提升通信安全性和减少终端设备的开销。
可选的，上述步骤201中，LMF可以通过会话向终端设备发送第二消息，该第二消息携带上述第一消息。该第二消息采用LMF与终端设备之间的定位协议，如长期演进(long term evolution，LTE)定位协议(LTE positioning protocol，LPP)，第一消息采用LMF与接入网设备之间的定位协议，如NRPPa。
步骤203，接入网设备根据第一消息，通过该会话向终端设备发送终端设备的位置信息。相应地，终端设备收到终端设备的位置信息。
该终端设备的位置信息用于计算终端设备的位置。
可选的，接入网设备确定终端设备的位置信息。该位置信息例如是location information，该位置信息可以包括定位参考信号(position reference singal，PRS)和/或探测参考信号(sounding reference signal，SRS)。
可选的，第一消息包括终端设备的关联标识和用于指示定位方法的信息。可选的，终端设备的关联标识用于关联该终端设备，该定位方法为接入网设备测量终端设备发送的无线信号，并上报终端设备的位置信息至LMF。例如，参考3GPP TS 38.455中9.1.1.1节中描述，第一消息包括的终端设备的关联标识可以通过LMF UE Measurement ID体现，第一消息包括的用于指示定位方法的信息可以通过Measurement Quantities Item体现。其中，Measurement Quantities Item可以包括Cell-ID,到达角(Angle of Arrival，AOA),时间提前类型1(Timing Advance Type 1),时间提前类型2(Timing Advance Type 2),参考信号接收功率(reference signal receiving power,RSRP),参考信号接收质量(reference signal receiving quality，RSRQ)中的一项或多项。
可选的，接入网设备基于第一消息向终端设备发送测量请求，该测量请求指示终端设备发送用于接入网设备测量的无线信号，终端设备根据测量请求向接入网设备发送无线信号。接入网设备测量该无线信号，得到终端设备的位置信息。可选的，该测量请求携带发送无线信号的频点、发送无线信号的时间、发送无线信号的时间间隔中的至少一项。
步骤204，终端设备通过该会话向LMF发送终端设备的位置信息。相应地，LMF收到终端设备的位置信息。
步骤205，LMF根据终端设备的位置信息，确定终端设备的位置。
该终端设备的位置，比如可以经纬度或坐标点等。
作为一种实现方法，上述会话中存在两条不同的服务质量(quality of service，QoS) 流，比如下行方向存在第一QoS流，上行方向存在第二QoS流。可选的，上述方案中，LMF通过第一QoS流向终端设备发送第一消息，终端设备通过第二QoS流向接入网设备发送第一消息，然后接入网设备通过第一QoS流向终端设备发送终端设备的位置信息，终端设备通过第二QoS流向LMF发送终端设备的位置信息。
基于上述方案，LMF通过会话，经由终端设备向接入网设备发送用于请求终端设备的位置信息的第一消息(也可以称为定位信令)，接入网设备基于第一消息，通过该会话，经由终端设备向LMF反馈终端设备的位置信息，从而LMF可以确定终端设备的位置，也即，该方法是通过用户面传递用于定位的定位信令和终端设备的位置信息。由于用户面路径较短且传输时延较短，因而可以实现快速传输用于定位的定位信令和终端设备的位置信息，进而可以降低定位终端设备的位置的时延，实现快速定位终端设备的位置。
并且，相较于上述提供的基于控制面传输用于定位的定位信令和终端设备的位置信息的方法，可以避免接入网设备与LMF之间的用于定位的定位信令和终端设备的位置信息需要经过控制面的AMF迂回，因而可以降低传输时延，进而可以降低定位终端设备的位置的时延，实现快速定位终端设备的位置。
参考图3，为本申请实施例提供的一种定位方法示意图。该方法包括以下步骤：
步骤301，LMF向SMF发送会话创建请求。相应地，SMF收到该会话创建请求。
该会话创建请求用于请求建立用于传输终端设备的位置信息的会话。
步骤302，SMF向接入网设备发送指示信息。相应地，接入网设备收到该指示信息。
SMF收到该会话创建请求后，建立该会话，并在建立会话的过程中，向接入网设备发送指示信息。可选的，还向终端设备发送LMF的位置信息。
该指示信息用于指示建立的会话与定位业务相关。由于LMF请求SMF创建的会话是用于传输终端设备的位置信息，也即与定位业务相关，因此SMF基于该会话建立请求向接入网设备发送该指示信息，以指示该会话与定位业务相关。
步骤303，LMF通过该会话向接入网设备发送第一消息。相应地，接入网设备通过该会话收到该第一消息。
该第一消息用于请求终端设备的位置信息。该第一消息例如是定位消息(position message)。
会话是用于为终端设备与数据网络(DN)之间提供数据连通性，终端设备的上下行数据需要通过会话来承载。该会话例如可以是协议数据单元(PDU)会话，PDU的类型可以是网络之间的互联协议(IP)，或者以太网(Ethernet)，或者无结构类型。
需要注意的是，第一消息也可以替换为一个容器(container)，该容器包括用于请求终端设备的位置信息的信息。
可选的，第一消息采用LMF与接入网设备之间的定位协议。可选的，该定位协议为NRPPa。可选的，当该定位协议是NRPPa，则该第一消息替换为NRPPa容器。
接入网设备收到上述指示信息，确定该会话与定位业务相关，因此可以基于该指示信息接收第一消息，并且解析该第一消息。也即，接入网设备根据该指示信息，截取第一消息，确定直接解析该第一消息，并基于该第一消息确定终端设备的位置信息。
步骤304，接入网设备根据第一消息，通过该会话向LMF发送终端设备的位置信息。相应地，LMF收到终端设备的位置信息。
该终端设备的位置信息用于计算终端设备的位置。
可选的，接入网设备确定终端设备的位置信息。该位置信息例如是location information，该位置信息可以包括定位参考信号(PRS)和/或探测参考信号(SRS)。
可选的，第一消息包括终端设备的关联标识和用于指示定位方法的信息。可选的，终端设备的关联标识用于关联该终端设备，该定位方法为接入网设备测量终端设备发送的无线信号，并上报终端设备的位置信息至LMF。例如，参考3GPP TS 38.455中9.1.1.1节中描述，第一消息包括的终端设备的关联标识可以通过LMF UE Measurement ID体现，第一消息包括的用于指示定位方法的信息可以通过Measurement Quantities Item体现。其中，Measurement Quantities Item可以包括Cell-ID,到达角(Angle of Arrival，AOA),时间提前类型1(Timing Advance Type 1),时间提前类型2(Timing Advance Type 2),参考信号接收功率(RSRP),参考信号接收质量(RSRQ)中的一项或多项。
可选的，接入网设备基于第一消息向终端设备发送测量请求，该测量请求指示终端设备发送用于接入网设备测量的无线信号，终端设备根据测量请求向接入网设备发送无线信号。接入网设备测量该无线信号，得到终端设备的位置信息。可选的，该测量请求携带发送无线信号的频点、发送无线信号的时间、发送无线信号的时间间隔中的至少一项。
步骤305，LMF根据终端设备的位置信息，确定终端设备的位置。

作为一种实现方法，上述会话中存在两条不同的QoS流，比如下行方向存在第一QoS流，上行方向存在第二QoS流。可选的，上述方案中，LMF通过第一QoS流向终端设备发送第一消息，终端设备通过第二QoS流向接入网设备发送第一消息，然后接入网设备通过第一QoS流向终端设备发送终端设备的位置信息，终端设备通过第二QoS流向LMF发送终端设备的位置信息。
基于上述方案，LMF通过会话向接入网设备发送用于请求终端设备的位置信息的第一消息(也可以称为定位信令)，接入网设备基于第一消息，通过该会话向LMF反馈终端设备的位置信息，从而LMF可以确定终端设备的位置，也即，该方法是通过用户面传递用于定位的定位信令和终端设备的位置信息。由于用户面路径较短且传输时延较短，因而可以实现快速传输用于定位的定位信令和终端设备的位置信息，进而可以降低定位终端设备的位置的时延，实现快速定位终端设备的位置。

步骤412，AMF向GMLC发送定位响应。相应地，GMLC收到该定位响应。
该定位响应携带终端设备的位置。
步骤413，GMLC向第三方设备发送定位响应。相应地，第三方设备收到该定位响应。
该定位响应携带终端设备的位置。
基于上述方案，LMF通过会话，经由终端设备向接入网设备发送用于请求终端设备的位置信息的NRPPa容器(也可以称为定位信令)，接入网设备基于NRPPa容器，通过该会话，经由终端设备向LMF反馈终端设备的位置信息，从而LMF可以确定终端设备的位置，也即，该方法是通过用户面传递用于定位的定位信令和终端设备的位置信息。由于用户面路径较短且传输时延较短，因而可以实现快速传输用于定位的定位信令和终端设备的位置信息，进而可以降低定位终端设备的位置的时延，实现快速定位终端设备的位置。
并且，相较于上述提供的基于控制面传输用于定位的定位信令和终端设备的位置信息的方法，可以避免接入网设备与LMF之间的用于定位的定位信令和终端设备的位置信息需要经过控制面的AMF迂回，因而可以降低传输时延，进而可以降低定位终端设备的位置的时延，实现快速定位终端设备的位置。
下面结合具体示例，对上述图3对应的定位方法进行具体说明。以下图5对应的实施例是上述图3对应的实施例的具体示例。参考图5，为本申请实施例提供的一种定位方法示意图。该方法包括以下步骤：
该方法包括以下步骤：
步骤501至步骤503，同上述步骤401至步骤403，可参考前述描述。
步骤504，LMF向SMF发送会话建立请求。相应地，SMF收到该会话建立请求。
该会话创建请求用于请求建立用于传输终端设备的位置信息的会话。可选的，该会话建立请求携带指示信息，该指示信息用于指示接入网设备的NRPPa层处理该会话的报文。
会话是用于为终端设备与数据网络(DN)之间提供数据连通性，终端设备的上下行数据需要通过会话来承载。该会话例如可以是协议数据单元(PDU)会话，PDU的类型可以是网络之间的互联协议(IP)，或者以太网(Ethernet)，或者无结构类型。作为一种可替代的实现方法，该步骤504也可以由以下步骤504’替换：
步骤504’，LMF向SMF发送会话修改请求。相应地，SMF收到该会话修改请求。
该会话修改请求用于请求SMF更新终端设备与LMF之间的会话，且该会话用于传输终端设备的位置信息。可选的，该会话建立请求携带指示信息，该指示信息用于指示接入网设备的NRPPa层处理该会话的报文。
步骤505，SMF向接入网设备发送指示信息。相应地，接入网设备收到该指示信息。
该指示信息用于指示建立的会话与定位业务相关。由于LMF请求SMF创建或更新的会话是用于传输终端设备的位置信息，也即与定位业务相关，因此SMF基于会话建立请求或会话修改请求，向接入网设备发送该指示信息，以指示该会话与定位业务相关。
步骤506，LMF通过会话向接入网设备发送报文。相应地，接入网设备通过会话收到报文。
可选的，该报文携带NRPPa容器，该NRPPa容器携带终端设备的关联标识和用于指示定位方法的信息。可选的，终端设备的关联标识用于关联该终端设备，该定位方法为接入网设备测量终端设备发送的无线信号，并上报终端设备的位置信息至LMF。可选的，该NRPPa容器采用LMF与接入网设备之间的NRPPa定位协议。
该报文是由LMF通过UPF发送至接入网设备的。作为一种实现方法，LMF获取LMF与UPF之间的隧道端点标识(Tunnel Endpoint Identifier,TEID)，然后将NRPPa容器封装在通用无线分组业务(General packet radio service，GPRS)隧道协议(GPRS Tunneling Protocol，GTP)报文，并将GTP报文通过该TEID对应的GTP隧道发送至接入网设备。
步骤507，接入网设备根据指示信息，处理该报文。
接入网设备从SMF收到上述指示信息后，确定该会话与定位业务相关，因此可以基于该指示信息接收并解析该报文。也即，接入网设备根据该指示信息，确定直接解析该报文，并基于该报文确定终端设备的位置信息。
比如，接入网设备解析报文并获取报文中的NRPPa容器，并从NRPPa容器中获取终端设备的关联标识和用于指示定位方法的信息。
步骤508，接入网设备确定终端设备的位置信息。
其中，接入网设备确定终端设备的位置信息的方法，可以参考前述实施例描述，不再赘述。该位置信息例如是location information，该位置信息可以包括定位参考信号(PRS)和/或探测参考信号(SRS)。
步骤509，接入网设备通过会话向LMF发送NRPPa消息。相应地，LMF通过会话收到NRPPa消息。
该NRPPa消息携带NRPPa容器，该NRPPa容器携带终端设备的位置信息。
该NRPPa消息是由接入网设备通过UPF发送至LMF的。
步骤510至步骤513，同上述步骤410至步骤413。
基于上述方案，LMF通过会话向接入网设备发送用于请求终端设备的位置信息的NRPPa容器(也可以称为定位信令)，接入网设备基于NRPPa容器，通过该会话向LMF反馈终端设备的位置信息，从而LMF可以确定终端设备的位置，也即，该方法是通过用户面传递用于定位的定位信令和终端设备的位置信息。由于用户面路径较短且传输时延较短，因而可以实现快速传输用于定位的定位信令和终端设备的位置信息，进而可以降低定位终端设备的位置的时延，实现快速定位终端设备的位置。
并且，相较于上述提供的基于控制面传输用于定位的定位信令和终端设备的位置信息的方法，可以避免接入网设备与LMF之间的用于定位的定位信令和终端设备的位置信息需要经过控制面的AMF迂回，因而可以降低传输时延，进而可以降低定位终端设备的位置的时延，实现快速定位终端设备的位置。
