技术领域technical field

本申请属于终端通信技术领域，具体涉及一种定位方法的确定方法、终端及网络侧设备。The present application belongs to the technical field of terminal communication, and in particular relates to a method for determining a positioning method, a terminal and a network side device.

背景技术Background technique

目前，在对目标终端进行定位时，可以使用多种定位方法实现。比如，可以使用基于蜂窝网的定位方法(可以称为RAT-dependent方法)对目标终端进行定位，即通过目标终端与基站之间的Uu口进行定位参考信号的发送和测量来实现定位，比如使用下行链路达到时间差(Down Link Time Difference of Arrival，DL-TDOA)的定位方法进行定位，或者，也可以使用不基于蜂窝网的定位方法(可以称为RAT-independent方法)对目标终端进行定位，比如使用全球卫星导航***(Global Navigation Satellite System，GNSS)进行定位，或者，还可以使用旁链路(sidelink，终端与其他节点(除基站)之间的通信链路，也可以称为副链路，直连链路，侧链路，边链路等)对目标终端进行定位。然而，在实际对目标终端进行定位时，还缺少一种有效的技术方案以确定具体使用哪种定位方法对目标终端进行定位。At present, when locating a target terminal, various locating methods can be used. For example, a positioning method based on a cellular network (which may be called a RAT-dependent method) can be used to locate the target terminal, that is, the positioning is realized by sending and measuring positioning reference signals through the Uu interface between the target terminal and the base station, such as using Downlink Time Difference of Arrival (Down Link Time Difference of Arrival, DL-TDOA) positioning method for positioning, or a positioning method not based on the cellular network (which may be called a RAT-independent method) can also be used to locate the target terminal, For example, use the Global Navigation Satellite System (GNSS) for positioning, or you can also use the sidelink (sidelink, the communication link between the terminal and other nodes (except the base station), which can also be called a secondary link , direct link, side link, side link, etc.) to locate the target terminal. However, when actually locating the target terminal, there is still a lack of an effective technical solution to determine which locating method is specifically used to locate the target terminal.

When determining the target positioning method according to the priority ranking of different positioning methods, it may be determined whether the condition of the first positioning method is satisfied according to the priority ranking of different positioning methods. Preferably, whether the condition of the first positioning method is satisfied can be determined sequentially according to the descending order of priorities of different positioning methods. If the judging result is that the condition of the first positioning method is satisfied, the first positioning method currently being judged is determined as the target positioning method and the judging step is stopped. If the judging result is that the condition of the first positioning method is not met, continue to judge the condition of the first positioning method with the next priority until the target positioning method is determined.

比如，在不同定位方法的优先级排序为旁链路定位方法和RAT-dependent方法之间的优先级排序且旁链路定位方法的优先级大于RAT-dependent方法的优先级，则可以先判断是否满足旁链路定位方法的条件，若满足，则将旁链路定位方法确定为目标定位方法，若不满足，则继续判断是否满足RAT-dependent方法的条件，若满足，则将RAT-dependent方法确定为目标定位方法。其中，若将旁链路定位方法确定为目标定位方法，则具体可以是将旁链路定位方法中的任一种定位方法作为目标定位方法，或者，也可以基于旁链路定位方法中的多种定位方法的优先级排序进行条件判断，并根据判断结果选择其中一种旁链路定位方法作为目标定位方法。For example, if the priority ranking of different positioning methods is the priority ranking between the sidelink positioning method and the RAT-dependent method, and the priority of the sidelink positioning method is greater than that of the RAT-dependent method, it can be determined first whether Satisfy the conditions of the side-link positioning method, if so, then determine the side-link positioning method as the target positioning method, if not, continue to judge whether the conditions of the RAT-dependent method are met, if satisfied, then use the RAT-dependent method identified as the targeting method. Wherein, if the side-link positioning method is determined as the target positioning method, specifically, any positioning method in the side-link positioning method may be used as the target positioning method, or it may also be based on multiple positioning methods in the side-link positioning method. According to the priority ranking of the positioning methods, the conditions are judged, and one of the side link positioning methods is selected as the target positioning method according to the judgment result.

If necessary, other UEs send feedback information to the Target UE. The feedback information of other UEs may be, for example, sidelink positioning capabilities of other UEs, zone information of other UEs, movement status of other UEs, location information of other UEs, and the like.

步骤17：Target UE根据收到的反馈信息情况，选出用于sidelink定位的Anchor UE。Step 17: The Target UE selects the Anchor UE for sidelink positioning according to the received feedback information.

步骤18：Target UE在选出Anchor UE后，Target UE定位Target UE的位置信息。Step 18: After the Target UE selects the Anchor UE, the Target UE locates the location information of the Target UE.

具体地，Target UE可以通过以下步骤18a-1至步骤18a-3定位Target UE的位置信息，或者，也可以通过以下步骤18b-1至步骤18b-3定位Target UE的位置信息，具体采用哪种方式可以由协议约定、由网络配置(比如网络预配置)、或由Target UE实现等。比如，如果网络侧设备已经预配置给Target UE，则可以通过步骤18a-1至步骤18a-3定位Target UE的位置信息，如果Target UE不具备配置sidelink定位配置信息的能力，则可以通过步骤18b-1至步骤18b-3定位Target UE的位置信息。Specifically, the Target UE can locate the location information of the Target UE through the following steps 18a-1 to 18a-3, or it can also locate the location information of the Target UE through the following steps 18b-1 to 18b-3, which one is used specifically? The method can be stipulated by the protocol, configured by the network (for example, pre-configured by the network), or realized by the Target UE, etc. For example, if the network side device has been pre-configured to the Target UE, the location information of the Target UE can be located through steps 18a-1 to 18a-3, and if the Target UE does not have the ability to configure sidelink positioning configuration information, it can be located through step 18b -1 to step 18b-3 locate the location information of the Target UE.

步骤18a-1：Target UE确定sidelink定位的配置信息(比如旁链路定位参考信号(Positioning Reference Signal，PRS)的配置)，可以是网络预配置，也可以是Target UE自己决定。然后Target UE发送该sidelink定位的配置信息给Anchor UE，同时向Anchor UE请求Anchor UE的位置信息等(可选地，如果步骤15中的反馈信息已经包含“其他UE的位置信息”，则可以不向Anchor UE请求Anchor UE的位置信息)。Step 18a-1: The Target UE determines the configuration information of sidelink positioning (such as the configuration of the Positioning Reference Signal (PRS) of the sidelink), which may be pre-configured by the network or determined by the Target UE itself. Then the Target UE sends the configuration information of the sidelink positioning to the Anchor UE, and at the same time requests the Anchor UE's location information, etc. Request the location information of the Anchor UE from the Anchor UE).

步骤18a-2：Anchor UE收到Target UE发送的sidelink定位的配置信息、Anchor UE位置信息的请求等后，Anchor UE向Target UE发送sidelink定位的测量结果、Anchor UE的位置信息等。Step 18a-2: After the Anchor UE receives the configuration information of sidelink positioning sent by the Target UE, the request for the location information of the Anchor UE, etc., the Anchor UE sends the measurement result of the sidelink positioning and the location information of the Anchor UE to the Target UE.

步骤18a-3：Target UE收到Anchor UE发送的sidelink定位的测量结果、Anchor UE的位置信息等后，Target UE根据测量结果、Anchor UE位置信息等，计算出Target UE的定位结果。Step 18a-3: After the Target UE receives the sidelink positioning measurement result sent by the Anchor UE, the location information of the Anchor UE, etc., the Target UE calculates the positioning result of the Target UE according to the measurement result and the location information of the Anchor UE.

步骤18b-1：Target UE向Anchor UE请求sidelink定位的配置信息(可以是只发请求，也可以同时发送sidelink定位的配置信息的内容)，同时向Anchor UE请求Anchor UE的位置信息等(可选地，如果步骤15中的反馈信息已经包含“其他UE的位置信息”，则可以不向Anchor UE请求Anchor UE的位置信息)。Step 18b-1: The Target UE requests the configuration information of the sidelink positioning from the Anchor UE (it can only send the request, or can also send the content of the configuration information of the sidelink positioning at the same time), and at the same time requests the location information of the Anchor UE from the Anchor UE, etc. (optional Specifically, if the feedback information in step 15 already includes "location information of other UEs", the location information of the Anchor UE may not be requested from the Anchor UE).

步骤18b-2：Anchor UE收到Target UE发送的请求信息后，Anchor UE向Target UE发送sidelink定位的配置信息、Anchor UE的位置信息等。Step 18b-2: After the Anchor UE receives the request information sent by the Target UE, the Anchor UE sends the configuration information of sidelink positioning, the location information of the Anchor UE, etc. to the Target UE.

步骤18b-3：Target UE收到Anchor UE发送的sidelink定位的配置信息、Anchor UE的位置信息等后，Target UE进行sidelink定位测量，根据测量结果、Anchor UE位置信息等，计算出Target UE的定位结果。Step 18b-3: After the Target UE receives the sidelink positioning configuration information sent by the Anchor UE, the location information of the Anchor UE, etc., the Target UE performs sidelink positioning measurement, and calculates the positioning of the Target UE according to the measurement results and the location information of the Anchor UE. result.

第二种应用场景：The second application scenario:

步骤21：Target UE的定位需要被获得，LMF接收location service request消息。Step 21: The location of the Target UE needs to be obtained, and the LMF receives the location service request message.

比如，Target UE的应用层有定位需求(比如，V2X app)且处于网络覆盖范围内，则Target UE向AMF发送location service request消息。AMF收到location service request消息后，AMF向LMF发送location service request消息。For example, if the application layer of the Target UE has positioning requirements (for example, V2X app) and is within the coverage of the network, the Target UE sends a location service request message to the AMF. After the AMF receives the location service request message, the AMF sends the location service request message to the LMF.

再比如，外部服务器(比如V2X server)有Target UE的定位需求，核心网的LCS entity向AMF发送location service request消息。AMF收到location service request消息后，AMF向LMF发送location service request消息。For another example, an external server (such as a V2X server) has a positioning requirement of a Target UE, and the LCS entity of the core network sends a location service request message to the AMF. After the AMF receives the location service request message, the AMF sends the location service request message to the LMF.

再比如，AMF有Target UE的定位需求，AMF向LMF发送location service request消息。For another example, the AMF has a positioning requirement of the Target UE, and the AMF sends a location service request message to the LMF.

步骤22：LMF收到location service request消息后，通过LPP消息(比如，Request Capabilities message)向Target UE and/orAnchor UE请求能力(比如，sidelink定位能力，DL-TDOA定位能力)。Step 22: After receiving the location service request message, the LMF requests capabilities (for example, sidelink positioning capability, DL-TDOA positioning capability) from the Target UE and/or Anchor UE through the LPP message (for example, Request Capabilities message).

步骤23：Target UE and/or Anchor UE收到LMF发送的能力请求消息后，Target UE and/or Anchor UE通过LPP消息(比如，Provide Capabilities message)向LMF反馈自己的能力信息(比如，sidelink定位能力，DL-TDOA定位能力)。Step 23: After Target UE and/or Anchor UE receives the capability request message sent by LMF, Target UE and/or Anchor UE feeds back its capability information (for example, sidelink positioning capability) to LMF through LPP message (for example, Provide Capabilities message) , DL-TDOA positioning capability).

步骤24：LMF根据收到的能力信息反馈情况和/或其他因素(比如，基站能力、QoS要求)从定位方法中确定目标定位方法(比如，决定采用sidelink定位方法，决定采用DL-TODA定位方法，决定采用sidelink定位方法和DL-TDOA定位方法两种定位方法。其中，sidelink定位方法的具体方法可以是四种sidelink定位方法中的任一种)。Step 24: The LMF determines the target positioning method from the positioning methods according to the received capability information feedback and/or other factors (such as base station capabilities, QoS requirements) (for example, decide to use the sidelink positioning method, decide to use the DL-TODA positioning method , it is decided to adopt two positioning methods, the sidelink positioning method and the DL-TDOA positioning method. Wherein, the specific method of the sidelink positioning method may be any one of the four sidelink positioning methods).
