具体地，终端101接入到移动基站102，移动基站102接入到主基站(Donor gNB)103，主基站103对外接入到核心网(Core Network，CN)104。在该场景中，终端101通过移动基站102接入网络，由于移动基站102在不停的移动，导致无法根据终端101当前接入的移动基站102确定定位参考信号的配置，进而实现定位功能。因此，在终端通过移动基站(Relay)接入网络的场景中，如何定位终端位置成为一个亟需解决的问题。Specifically, the terminal 101 is connected to the mobile base station 102, the mobile base station 102 is connected to the primary base station (Donor gNB) 103, and the primary base station 103 is externally connected to the core network (Core Network, CN) 104. In this scenario, the terminal 101 accesses the network through the mobile base station 102. Since the mobile base station 102 is constantly moving, it is impossible to determine the configuration of the positioning reference signal according to the mobile base station 102 currently accessed by the terminal 101, thereby realizing the positioning function. Therefore, in a scenario where a terminal accesses a network through a mobile base station (Relay), how to locate the location of the terminal becomes an urgent problem to be solved.

第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)在R16完成了基于NR信号进行终端定位的一个版本，弥补了R15标准不支持基于NR信号进行定位的不足。目前，3GPP R16版本的定位标准支持各种基于NR信号的上、下行定位技术，终端和基站定位测量，上、下行定位参考信号设计，定位过程以及基于NR信号进行终端定位的功能。The 3rd Generation Partnership Project (3GPP) completed a version of terminal positioning based on NR signals in R16, which made up for the deficiency that the R15 standard does not support positioning based on NR signals. Currently, the positioning standards of the 3GPP R16 version support various NR signal-based uplink and downlink positioning technologies, terminal and base station positioning measurement, uplink and downlink positioning reference signal design, positioning process and terminal positioning based on NR signals.
常见的基于下行定位参考信号(Positioning Reference Signal,PRS)(即DL PRS)或者上行探测参考信号(Sounding Reference Signal,SRS)(即UL SRS)进行的定位方法包括基于到达时差定位法(Time  difference of Arriva，TDOA)或者基于角度的定位法。其中，在终端直接接入接入网设备的情况下，DL PRS一般由接入网设备发送，终端进行测量，并将测量结果或者定位估计结果上报给LMF。在终端直接接入接入网设备的情况下，UL SRS由终端发送，接入网设备进行测量，并将测量结果上报给LMF。LMF基于终端和/或接入网设备的测量结果或者定位估计结果，解算出终端位置。Common positioning methods based on downlink positioning reference signal (Positioning Reference Signal, PRS) (ie DL PRS) or uplink sounding reference signal (Sounding Reference Signal, SRS) (ie UL SRS) include positioning based on time difference of arrival (Time difference of Arriva, TDOA) or angle-based positioning. Among them, when the terminal directly accesses the access network device, the DL PRS is generally sent by the access network device, and the terminal performs measurement and reports the measurement result or location estimation result to the LMF. In the case that the terminal directly accesses the access network device, the UL SRS is sent by the terminal, and the access network device performs measurement and reports the measurement result to the LMF. The LMF calculates the location of the terminal based on the measurement results or location estimation results of the terminal and/or access network equipment.
在上述定位过程中，为支持PRS和SRS的测量，LMF需要为终端或接入网设备配置合适的PRS或者SRS，并且指示终端或接入网设备去测量合适的PRS或者SRS。目前，LMF确定PRS或者SRS配置，或者指示终端或者接入网设备去测量的具体的PRS或者SRS时，是根据终端当前接入的具体接入网设备的位置确定的。但在终端通过移动基站接入接入网设备的工作场景中，由于移动基站在不停的移动，LMF无法确定PRS或者SRS的配置，进而无法实现定位功能，导致终端当前的位置难以确定。In the above positioning process, in order to support PRS and SRS measurement, LMF needs to configure appropriate PRS or SRS for terminal or access network equipment, and instruct terminal or access network equipment to measure appropriate PRS or SRS. At present, when the LMF determines the PRS or SRS configuration, or instructs the terminal or the access network device to measure the specific PRS or SRS, it is determined according to the location of the specific access network device currently accessed by the terminal. However, in the working scenario where the terminal accesses the access network equipment through the mobile base station, because the mobile base station is constantly moving, the LMF cannot determine the configuration of the PRS or SRS, and thus cannot realize the positioning function, making it difficult to determine the current location of the terminal.
为了解决该问题，在本申请实施例中，将移动基站的位置作为接入到移动基站的终端的位置，这样即使移动基站在不停的移动，仍然可以确定终端的位置，实现对终端的有效定位。本申请具体可以通过以下方案一或方案二实现。方案一和方案二的区别在于，方案一中LMF将移动基站的位置作为终端的位置，并将移动基站的位置发送给终端，方案二中，移动基站获取自身位置，并将自身位置发送给终端。以下对方案一和方案二具体进行描述。In order to solve this problem, in the embodiment of the present application, the position of the mobile base station is used as the position of the terminal connected to the mobile base station, so that even if the mobile base station is constantly moving, the position of the terminal can still be determined, and effective monitoring of the terminal can be realized. position. The present application can specifically be realized through the following scheme 1 or scheme 2. The difference between scheme 1 and scheme 2 is that in scheme 1, the LMF uses the location of the mobile base station as the location of the terminal, and sends the location of the mobile base station to the terminal. In scheme 2, the mobile base station obtains its own location and sends its own location to the terminal . The scheme 1 and scheme 2 are described in detail below.

该情况下，方式2在具体实现时可以包括：LMF与第一指示信息指示的移动基站执行定位流程，获取移动基站的定位信息，根据定位信息确定移动基站的位置。In this case, method 2 may include: the LMF executes a positioning process with the mobile base station indicated by the first indication information, acquires the positioning information of the mobile base station, and determines the position of the mobile base station according to the positioning information.
其中，LMF与移动基站可以采用合适的定位方法，执行定位流程。使用的定位方法可以是以下方法中的一种或多种：基于LTE信号的增强型小区ID(Enhanced Cell ID,E-CID)定位方法,基于NR信号的NR增强小区ID(NR E-CID)定位方法，基于NR信号的上行到达时间差的定位方法(UL-TDOA)，基于NR信号的上行到达角定位方法(UL-AoA)，基于NR信号的下行到达时间差的定位方法(DL-TDOA)，基于NR信号的下行离开角度的定位方法(DL-AOD)，基于NR信号的多次往返时间定位方法(Multi-RTT)，基于LTE信号的观测到达时间差(OTDOA)定位方法，本申请实施例不做限制。具体的定位流程为本领域技术人员所熟知的，此处不再赘述。Wherein, the LMF and the mobile base station can adopt a suitable positioning method to execute a positioning process.

Optionally, LCS QoS requirements may include one or more of the following parameters: LCS QoS level, positioning accuracy and response time.
其中，LCS QoS等级定义了定位业务和其他QoS参数(如精度)的依赖程度。LCS QoS等级分为两种，一是尽力而为等级(Best effort class)，二是确定等级(Assured Class)。尽力而为等级定义了最宽松的QoS要求，即，如果当前估计的位置无法满足其他QoS需求，该定位结果仍然可以被反馈到定位请求端。如果无法获得估计的位置，则反馈一个Error。确定等级定义了一个位置请求可满足的最严格的精度需求。即，如果当前估计的位置无法满足其他QoS需求，该定位结果将被丢弃。Among them, the LCS QoS level defines the degree of dependence between positioning services and other QoS parameters (such as accuracy). There are two types of LCS QoS classes, one is Best effort class and the other is Assured Class. The best-effort level defines the most relaxed QoS requirements, that is, if the current estimated position cannot meet other QoS requirements, the positioning result can still be fed back to the positioning requester. If the estimated position cannot be obtained, an Error is returned. The certainty level defines the most stringent accuracy requirements that a location request can satisfy. That is, if the current estimated location cannot meet other QoS requirements, the positioning result will be discarded.
定位精度可以分为水平精度和垂直精度。响应时间可以分为无延时、低延时、和时延容忍。Positioning accuracy can be divided into horizontal accuracy and vertical accuracy. Response time can be divided into no delay, low delay, and delay tolerance.

In addition, the uplink NAS message sent by the terminal may also be a NAS Location Notification Feedback Result (NAS Location Notification Return Result) message, which is responsible for privacy verification of the terminal. The NAS location notification feedback result message is triggered by a positioning request initiated by an external AF or an external client, that is, a Mobile Terminated Location Request (MT-LR) request. That is, the NAS message in S22) may be the MO-LR request message itself, or the privacy verification feedback message triggered by the MT-LR. That is to say, the positioning process involved in this application can be based on MO-LR request or MT-LR request. This application does not limit it. The detailed process of specific MO-LR and MT-LR request process can refer to 3GPP The relevant descriptions in the communication protocol TS 23.273 will not be repeated here.
参照通信协议(例如TS32.272)，目前定位请求可以包括三种，分别是MO-LR,MT-LR和网络诱发位置请求(Network Induced Location Request,NI-LR)。Referring to the communication protocol (such as TS32.272), the current location request can include three types, namely MO-LR, MT-LR and Network Induced Location Request (NI-LR).
具体地，MO-LR是移动终端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 LCS客户端、内部或外部AF向当前服务PLMN发起的位置请求；NI-LR是终端的服务AMF为监管业务发起的位置请求，如终端的紧急呼叫。Specifically, MO-LR is the location request sent by the mobile terminal to the current serving Public Land Mobile Network (PLMN); MT-LR is the location request initiated by the LCS client, internal or external AF to the current serving PLMN ; NI-LR is the location request initiated by the service AMF of the terminal for supervision services, such as the emergency call of the terminal.

S303在具体实现时，在LMF中不存在满足终端的LCS QoS需求的移动基站的定位结果的情况下，LMF可以通过方式1或方式2获取移动基站的位置，并向终端发送移动基站的位置。在LMF中存在满足终端的LCS QoS需求的移动基站的定位结果的情况下，将满足LCS QoS需求的移动基站的定位结果发送至终端。针对后者，S301在具体实现时，LMF可以从本地获取移动基站的位置。In specific implementation of S303, if there is no positioning result of the mobile base station that meets the LCS QoS requirements of the terminal in the LMF, the LMF can obtain the position of the mobile base station through mode 1 or mode 2, and send the position of the mobile base station to the terminal. If there is a positioning result of the mobile base station that meets the LCS QoS requirement of the terminal in the LMF, the positioning result of the mobile base station that meets the LCS QoS requirement is sent to the terminal. Regarding the latter, when S301 is specifically implemented, the LMF may locally obtain the location of the mobile base station.
其中，LMF可以在确定存在满足终端的LCS QoS需求中的部分或全部参数的移动基站的定位结果的情况下，确定存在满足终端的LCS QoS需求的移动基站的定位结果，否则，确定不存在满足终端的LCS QoS需求的移动基站的定位结果。Among them, the LMF can determine that there is a positioning result of the mobile base station that meets the LCS QoS requirements of the terminal when it is determined that there is a positioning result of the mobile base station that meets some or all of the parameters in the LCS QoS requirements of the terminal; The positioning result of the mobile base station according to the LCS QoS requirement of the terminal.
在一个非限制性的具体实施方式中，LMF可以先判断LCS QoS等级是否满足需求，若是，再确认定位精度是否满足需求，若是，再确定响应时间是否满足需求，若是，则确定存在满足终端的LCS QoS需求的移动基站的定位结果，否则，确定不存在满足终端的LCS QoS需求的移动基站的定位结果。需要指出的是，此处的判断顺序以及判断的参数个数仅仅为示例，在实际实现时可以有其他顺序和/或参数 个数，本申请不作限制。In a non-limiting specific implementation, the LMF can first judge whether the LCS QoS level meets the requirements, if so, then confirm whether the positioning accuracy meets the requirements, if so, then determine whether the response time meets the requirements, and if so, determine that there is a location that meets the requirements of the terminal Otherwise, it is determined that there is no positioning result of the mobile base station that meets the LCS QoS requirements of the terminal. It should be pointed out that the order of judgment and the number of parameters for judgment here are only examples, and there may be other orders and/or numbers of parameters in actual implementation, which are not limited in this application.
在图3示出的定位方法中，终端发送NAS消息至AMF，AMF发送确定位置请求消息至LMF，LMF获取移动基站的位置，并向终端发送移动基站的位置，或者，终端发送NAS消息至AMF，AMF将满足终端的LCS QoS需求的移动基站的定位结果发送至终端，从而可以有效确定终端的定位，填补现有技术中的空白。In the positioning method shown in Figure 3, the terminal sends a NAS message to the AMF, and the AMF sends a location determination request message to the LMF, and the LMF acquires the location of the mobile base station and sends the location of the mobile base station to the terminal, or the terminal sends a NAS message to the AMF , AMF sends the positioning result of the mobile base station that meets the LCS QoS requirements of the terminal to the terminal, so that the positioning of the terminal can be effectively determined and the gap in the existing technology is filled.

本申请实施例中，终端的NAS层向AS层发送定位消息，使得终端可以直接通过AS层信令向其接入的移动基站发送第一定位请求信息，从而将现有方案中的定位请求消息的传输从NAS层发送转移 到AS层发送，信令跳数从4跳降低到了1跳，大大降低了定位时延，简化了定位的信令开销，以实现通过移动基站对终端的定位的目的。In the embodiment of this application, the NAS layer of the terminal sends a positioning message to the AS layer, so that the terminal can directly send the first positioning request information to the mobile base station it accesses through AS layer signaling, so that the positioning request message in the existing solution The transmission is transferred from the NAS layer to the AS layer, and the number of signaling hops is reduced from 4 hops to 1 hop, which greatly reduces the positioning delay and simplifies the signaling overhead of positioning, so as to realize the positioning of the terminal through the mobile base station .
