降低定位功耗的方法、网元、终端、装置及存储介质
相关申请的交叉引用
本公开要求于2022年05月06日提交的申请号为202210489993.8，发明名称为“降低定位功耗的方法、网元、终端、装置及存储介质”的中国专利申请的优先权，其通过引用方式全部并入本文。
技术领域
本公开涉及通信技术领域，尤其涉及一种降低定位功耗的方法、网元、终端、装置及存储介质。
背景技术
在相关技术中，由无线接入网(Radio Access Network,RAN)节点决定是否执行低功耗定位，因RAN节点可获取的信息较少，例如无法获得用户设备(User Equipment，UE)签约信息、位置服务(Location Services，LCS)客户端类型、业务类型等只有核心网网元才可获取的信息，所以相关技术不能支持更多的需求，例如无法支持对具有特定签约的UE执行低功耗定位，或者无法对特定类型的LCS客户端执行低功耗定位。
另外，相关技术只能降低推迟的定位过程的事件报告过程中的UE功耗，未考虑如何降低一次性定位过程的UE功耗，尤其是如何降低移动范围有限的设备(例如在工厂内运输物料的车，机械臂等)或静态物联网(Internet of Things，IoT)设备的一次性定位的功耗。

首先对本发明涉及的相关内容进行介绍。
1)位置服务架构
位置服务架构如图1所示。位置服务架构中UE和各网元的主要功能简介如下：
UE根据定位请求获取位置测量信息，在本地计算位置或将测量信息转发至位置管理功能(Location Management Function，LMF)进行位置计算。UE和LMF之间沿用了4G系统的LTE定位协议(LTE Positioning Protocol，LPP)协议。
(R)AN参与对目标UE进行定位的定位过程，向LMF提供定位相关信 息，并在AMF或LMF和目标UE之间传输定位消息。LMF和gNB之间使用的是NR定位协议A(NR positioning protocol A，NRPPa)协议。
网关移动定位中心(Gateway Mobile Location Centre，GMLC)是外部LCS客户端请求定位服务时，访问公共陆地移动网络(public land mobile network，PLMN)的第一个节点，GMLC从UDM获取路由信息以及UE LCS隐私属性，进行隐私检查，然后根据路由信息转发定位消息。
位置请求功能(Location Require Function，LRF)为发起互联网多媒体子系统(IP Multimedia Subsystem，IMS)紧急会话的UE提供路由信息，可与GMLC进行合设。
UDM存储UE的LCS隐私设置和路由信息。
AMF管理从GMLC、NEF或UE接收到的定位请求，为定位请求选择LMF，支持加密辅助数据的广播，和UE定位能力存储。
LMF负责管理和调度对UE进行定位所需的资源，当从服务AMF接收到定位请求时，LMF与UE和接入网络交互获取定位辅助信息或位置信息。LMF可决定使用局部坐标系。
NEF可向应用功能(Application Function，AF)开放位置服务。
2)低功耗定位
相关技术中，在推迟的5G核心网移动终止位置请求(5GC Mobile Terminated Location Request，5GC-MT-LR)过程中，LMF向UE发送事件类型及相关信息后，UE可进入RRC非激活(RRC_INACTIVE)状态。
处于RRC_INACTIVE状态的UE监测到事件发生时，UE向LMF发送事件通知，该事件报告内可能包括测量信息，LMF还可能请求RAN节点提供测量信息。LMF根据测量计算UE位置，然后向UE返回事件报告确认。
RAN节点可在发送事件报告确认后，释放无线资源控制(Radio Resource Control，RRC)连接，使得UE保持在RRC_INACTIVE状态。
因为上述过程不需要UE进入连接态，因此降低了UE功耗。
相关的降低定位功耗的技术对核心网透明，因此无法支持特定场景下的UE低功耗定位，例如对于具有特定签约的UE、特定的LCS客户端类型，或 特定的LCS服务质量(Quality of Service,QoS)。
相关降低定位功耗的技术仅能降低推迟的定位过程的事件报告过程的UE功耗，未考虑如何在一次性定位过程中降低功耗，尤其是如何降低移动范围有限的设备(例如在工厂内运输物料的车，机械臂等)或静态IoT设备的一次性定位的功耗。
为了解决上述问题，本申请实施例提供了降低定位功耗的方法、网元、终端、装置及存储介质，用以解决相关技术中无法支持特定场景下或具有特定需求的终端的低功耗定位的缺陷。
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。
图2为本发明实施例提供的降低定位功耗的方法的流程示意图之一。如图2所示，该降低定位功耗的方法包括：
步骤200、第一网元向第二网元或第三网元发送第一消息，所述第一消息中携带低功耗指示和/或区域信息，所述低功耗指示用于指示执行低功耗定位过程，所述区域信息用于指示允许终端发送事件报告的区域。
需要说明的是，在本发明实施例中，第一网元可以是AMF网元，也可以是其他能够实现本发明实施例中第一网元的功能的其他CN网元。下面以第一网元为AMF网元为例进行说明。
第二网元可以是RAN网元。第三网元可以是LMF网元，或其他能够实现本发明实施例中第三网元的功能的其他CN网元。
一种实施方式中，第一网元向第二网元发送第一消息包括：AMF网元向RAN网元发送第一消息。具体地，第一消息为寻呼消息，该寻呼消息中携带低功耗指示，所述低功耗指示用于指示执行低功耗定位过程。低功耗指示也可以称为低功耗定位指示，两者在本申请中含义相同。
RAN网元接收来自第一网元的第一消息，第一消息中携带低功耗指示，则RAN网元开始寻呼UE，向UE发送寻呼消息，该寻呼消息中携带低功耗指示。UE监听到寻呼消息，根据低功耗指示，执行低功耗定位过程，即在空闲态或非激活态执行定位测量，并将测量结果发送至第一网元。
另一种实施方式中，第一网元向第二网元发送第一消息包括：AMF网元向LMF网元发送第一消息。具体地，第一消息为定位请求消息，所述定位请求消息用于请求LMF网元计算UE位置。所述第一消息中携带低功耗指示，所述低功耗指示用于指示执行低功耗定位过程，从而触发LMF网元执行低功耗定位过程。
LMF网元执行低功耗定位过程，包括以下至少一项：减少测量次数、减少测量参数、触发UE执行低功耗定位过程，提供低功耗定位配置信息，计算UE位置。
其中，低功耗定位配置信息为终端执行低功耗定位过程所需的信息，例如测量次数，测量参数、定位方法等。
可选地，AMF网元向LMF网元发送的第一消息中还携带测量信息，该测量信息是终端执行低功耗定位过程获得的。
在一些可选的实施方式中，第一网元向第二网元或第三网元发送第一消息，第一消息中携带区域信息，所述区域信息用于指示允许终端发送事件报告的区域。
可以理解，终端位于区域信息所指示的区域内才会上报事件报告。
下面通过一个具体的实施例对区域信息的使用进行描述。
1、LCS客户端向GMLC网元发送位置请求消息，携带区域信息。该区域信息表明UE位于该区域内时发送事件报告。
2、GMLC网元向AMF网元发送位置请求消息，携带区域信息。
3、AMF网元向LMF网元发送位置请求消息，携带区域信息。
4、LMF网元向UE发送LCS周期触发调用请求消息，携带区域信息。
5、UE接收到该信息后，当UE发现事件发生时(例如定位周期到达，或者UE的移动距离超过特定的长度)，只有UE位于上述区域信息指示的区域内时，UE才执行定位测量，位置计算，以及向网络发送事件报告。
需要说明的是，当UE监测到事件发生时，只有UE位于上述区域信息指示的区域内时，UE才执行执行定位测量，位置计算，以及向网络发送事件报告等操作，从而避免了UE在每次事件发生时都执行上述操作，因此降低了 功耗。
在本发明实施例中，通过第一网元向第二网元或第三网元发送第一消息，第一消息中携带低功耗指示和/或区域信息，低功耗指示用于指示执行低功耗定位过程，区域信息为允许终端发送事件报告的区域，由核心网网元确定执行低功耗定位，并向第二网元或第三网元发送第一消息，从而触发终端执行低功耗定位过程，减少了UE和网络的交互以及UE处于连接态的时间，降低了定位功耗，能够支持特定场景下或具有特定需求的终端的低功耗定位，实用性强。
在一种可选的实施方式中，所述第一网元向第二网元或第三网元发送第一消息之前，所述方法还包括：
确定第一信息中携带低功耗指示，其中，所述第一信息包括以下至少一项：终端能力，客户端请求消息，终端请求消息，LCS服务质量，终端签约信息，终端的服务小区，网络能力，运营商策略，LCS客户端类型，服务类型。
可以理解的是，由第一网元确定触发低功耗定位，第一网元根据以下信息中的一项或多项确定触发低功耗定位：
1)终端能力：支持低功耗定位的能力；
2)客户端请求消息，客户端请求消息包括：AF/LCS客户端请求消息，即AF/LCS客户端提供低功耗相关信息，该低功耗相关信息可以是新定义的参数，也可以包含在相关的LCS QoS内(要做低功耗定位)；
3)终端请求消息：UE提供低功耗相关信息，该低功耗相关信息可以是新定义的参数，也可以包含在相关的LCS QoS内；
4)LCS服务质量(LCS QoS)：LCS QoS内包含低功耗相关信息；
5)终端签约信息，例如，低功耗签约信息，LCS隐私属性包括低功耗指示；
6)终端的服务小区；
7)网络能力：网络设备中RAN网元、核心网网元支持低功耗定位能力；
8)运营商策略；
9)LCS客户端类型，例如，特定LCS客户端类型(如公安使用的LCS客户端)；
10)服务类型，例如，非紧急服务；
11)终端信息，例如电量、上层应用请求、所处环境等。
在本发明实施例中，第一网元根据第一信息确定执行低功耗定位，相比于相关技术只能由RAN网元确定是否执行低功耗定位，能够支持特定场景下或具有特定需求的终端的低功耗定位。
值得说明的是，本发明实施例提供的降低定位功耗的方法，决定是否执行低功耗定位的也可以是UE，或其他网络功能(例如，第二网元(如RAN网元)，第三网元(如LMF网元)，第四网元(如GMLC网元))。
低功耗定位的决策点不同，需要在不同NF之间传输低功耗指示：
a)如果由GMLC网元决定，则GMLC网元向AMF网元发送低功耗指示，AMF网元向LMF网元发送低功耗指示；
b)如果由AMF网元决定，则AMF网元向LMF网元发送低功耗指示；
c)如果由UE决定，则UE向AMF网元发送低功耗指示，AMF网元向LMF网元发送低功耗指示；
d)如果由LMF网元决定，则LMF网元向UE或RAN节点发送低功耗指示。
支持低功耗定位，对网络功能选择的影响：
a)GMLC网元选择AMF网元时，选择支持低功耗定位能力的AMF网元。GMLC网元本地配置有AMF网元的能力或从NRF网元获取AMF网元的能力。
b)AMF网元选择LMF网元时，选择支持低功耗定位能力的LMF网元。AMF网元本地配置有LMF网元的能力或从NRF网元获取LMF网元的能力。
c)RAN节点选择AMF网元时，选择支持低功耗定位能力的AMF网元。UE发送给RAN节点的AN参数中包括低功耗指示。
当LMF网元接收到低功耗指示后，LMF网元可降低测量次数，触发IDLE或RRC_INACTIVE定位等相关的降低功耗的过程。对于移动范围有限的设 备(例如在工厂内运输物料的车，机械臂等)或静态IoT设备，本发明通过提前向这些设备提供低功耗定位配置信息，上述UE可在空闲态或非激活态使用低功耗定位配置信息执行定位测量，通过减少UE和网络的交互以及减小UE处于连接态的时间，降低定位功耗。
在一种可选的实施方式中，所述第一网元向第二网元或第三网元发送第一消息之前，所述方法还包括：
接收来自第四网元的定位请求消息，所述定位请求消息中携带低功耗指示。
需要说明的是，第四网元可以是GMLC网元。
其中，第四网元可以是从LCS客户端接收到低功耗指示，该低功耗指示可以是新定义的参数，也可以是现有参数。
如果使用现有参数，可为该现有参数定义新的可取值或新增子参数。例如在LCS QoS参数内引入低功耗定位参数，或者定义新的服务类型Service type或LCS客户端类型(Client type)的可取值(如低功耗定位)。
第一网元接收来自第四网元的定位请求消息，所述定位请求消息中携带低功耗指示，从而第一网元向第二网元或第三网元发送第一消息，从而在不同NF之间传输低功耗指示。
需要说明的是，若第一网元接收来自第四网元的定位请求消息中未携带低功耗指示，则第一网元确定第一信息中携带低功耗指示。
可选地，所述第一网元向第二网元或第三网元发送第一消息之前，所述方法还包括：
所述第一网元接收来自终端或所述第二网元的第二消息，所述第二消息中携带以下至少一项：第一能力信息；低功耗定位请求消息；低功耗指示；
可选地，第二网元向第一网元发送第二消息，是指转发终端发送的第二消息。
一种可选的实施方式中，第一网元向第二网元或第三网元发送第一消息之前，第一网元接收来自终端或第二网元的第二消息，第二消息中携带第一能力信息。
其中，所述第一能力信息用于指示所述终端支持低功耗定位。
在第一网元发送低功耗指示之前，终端与第一网元进行能力协商。
图3为本发明实施例提供的终端与第一网元进行能力协商的示意图。如图3所示，终端与第一网元进行能力协商的过程包括：
1、UE向RAN节点发送接入消息，接入消息携带支持注册请求消息和第一能力信息(可选)。其中注册请求消息中携带第一能力信息。RAN节点根据UE支持低功耗定位能力选择支持该能力的AMF。
2、RAN节点向AMF发送N2消息，消息携带步骤1的注册请求消息。
3、AMF向RAN节点发送N2消息，消息携带注册接受消息。AMF可能在注册接受消息中携带接受/拒绝低功耗定位，例如AMF根据自身能力、网络能力、UE签约、网络策略等判断是否可为UE提供低功耗定位服务。
4、RAN节点向UE发送接入回复消息，所述接入回复消息中携带注册接受消息，所述注册接受消息中携带第一指示信息，所述第一指示信息用于指示接受低功耗定位或拒绝低功耗定位。
一种可选的实施方式中，第一网元向第二网元或第三网元发送第一消息之前，第一网元接收来自终端或第二网元的第二消息，第二消息中携带低功耗定位请求消息。
在本发明实施例中，低功耗定位请求消息，用于请求执行低功耗定位过程，或者用于请求执行低功耗定位过程所需的信息。
可以理解，终端或第二网元向第一网元发送低功耗定位请求消息，第一网元接收到该低功耗定位请求消息，向第二网元或第三网元发送第一消息，从而实现了在NF之间传输低功耗指示，可以触发终端执行低功耗定位过程。
一种可选的实施方式中，第一网元向第二网元或第三网元发送第一消息之前，第一网元接收来自终端或第二网元的第二消息，第二消息中携带低功耗指示。
终端或第二网元向第一网元发送第二消息，第二消息中携带低功耗指示，该低功耗指示可以是新定义的参数，也可以是现有参数。如果使用现有参数，可为该现有参数定义新的可取值或新增子参数。例如在LCS QoS参数内引入 低功耗定位参数，或者定义新的服务类型Service type或LCS客户端类型(Client type)的可取值(如低功耗定位)。
一种可选的实施方式中，第一网元向第二网元或第三网元发送第一消息之前，第一网元接收来自终端或第二网元的第二消息，第二消息中携带第一能力信息，低功耗定位请求消息和低功耗指示中的至少两项。
需要说明的是，若第一网元接收来自终端或第二网元的第二消息中未携带低功耗指示，则第一网元确定第一信息中携带低功耗指示。
图4为本发明实施例提供的UE或网络功能决定触发低功耗定位的流程示意图。如图4所示，UE或网络功能决定触发低功耗定位包括：
1、AMF从UE接收到低功耗定位请求消息(即图4 1b中的移动始发位置请求(mobile originating location request，MO-LR)消息)或从GMLC接收到定位请求消息(即图4 0a中的位置请求消息)，消息携带低功耗指示。其中，GMLC是从LCS客户端接收到低功耗指示。该低功耗指示可以是新定义的参数，也可以是现有参数。如果使用现有参数，可为该参数定义新的可取值或新增子参数。例如在LCS QoS参数内引入低功耗定位参数，或者定义新的service type或LCS Client type的可取值(如低功耗定位)。
或者步骤1a和步骤1b未携带低功耗定位指示，AMF决定触发低功耗定位。例如AMF可根据UE能力，UE签约，网络能力，运营商策略，UE服务小区，LCS client type，service type等参数做出决策。
2、AMF向LMF发送第一消息(此处为决定UE位置请求消息)，第一消息携带低功耗指示。如果LMF未从AMF接收到低功耗指示，LMF也可能确定执行低功耗定位，例如根据LCS QoS，LCS client type，service type，UE能力，运营商策略，UE的服务小区等。LMF触发低功耗定位的操作，例如减少测量参数，触发RRC_INACTIVE定位等。
可以理解，若第一网元接收来自终端或第二网元的第二消息中未携带低功耗指示，或者，第一网元接收来自第四网元的定位请求消息中未携带低功耗指示，则第一网元确定第一信息中携带低功耗指示，若第三网元未从第一网元接收到低功耗指示，则第三网元也可能确定是否执行低功耗定位。具体 的，第三网元根据第一信息确定执行低功耗定位。第一信息可以参考前述实施例中的描述，在此不再赘述。
可选地，所述方法还包括：
向所述终端或第二网元发送第二回复消息，所述第二回复消息中携带低功耗定位配置信息。
可以理解，第二网元接收到第一网元发送的第一消息后，第二网元会寻呼UE，从而在UE监听到寻呼中，执行低功耗定位过程。第三网元接收到第一网元发送的第一消息后，第三网元会触发UE执行低功耗定位过程。
在本发明实施例中，终端根据提前获得的低功耗定位配置信息，执行低功耗定位过程。低功耗定位配置信息为终端执行低功耗定位过程中所需要的信息。
本发明实施例关注的是网络提前将低功耗定位配置信息提供给UE，UE进入空闲(IDLE)态或非激活态(RRC_INACTIVE)后，当UE需要定位时，UE根据从网络接收到的低功耗定位配置信息执行定位测量，然后通过业务请求(service request)消息将测量结果提供给网络，LMF计算UE位置，并将结果通过service accept发送给UE。然后，UE再次进入IDLE态。该方法提前将低功耗定位配置信息提供给UE，UE可在IDLE态或RRC_INACTIVE态下执行定位测量，本发明实施例通过减少UE和网络的交互，以及减小UE处于连接态的时间，降低了定位功耗。
