在基于移动通信网络进行测距的过程中。请求端可以对一个终端进行绝对位置信息的测距，也可以对两个终端的相对位置信息进行测距/SL定位。若对终端进行位置信息测量时会得到终端的位置信息，在一些情况下，终端会拒绝暴露自身的位置信息。此时继续对终端进行位置信息进行测量，则可能导致终端的隐私被泄露。因此在终端拒绝位置信息暴露的情况下，如何进行测距/SL定位请求的响应还没有相关规范。In the process of ranging based on the mobile communication network, the requesting end can measure the absolute position information of a terminal, or measure the relative position information of two terminals/SL positioning. If the terminal's position information is measured, the terminal's position information will be obtained. In some cases, the terminal will refuse to disclose its own position information. At this time, continuing to measure the terminal's position information may cause the terminal's privacy to be leaked. Therefore, how to make a ranging/SL positioning request when the terminal refuses to disclose its position information? There is no specification for responses.

The communication device involves a requesting end and a network device, etc. The ranging method shown in FIG2A includes: after the first network device receives a ranging/SL positioning request from the requesting end for n terminals, the terminal information of the n terminals that refuses to expose the location information can be determined according to the privacy configuration of the n terminals, and whether to initiate ranging/SL positioning is determined according to the information of the terminal that refuses the location information. The embodiment of this scheme is: when the first network device determines the terminal information of the n terminals that refuses to expose the location information according to the first indication of the privacy configuration, and when the first network device determines that the privacy configuration of the terminal that accepts the exposure of the location information includes the second indication according to the first indication, the third network device is requested to obtain the user indication. The third network device will obtain the user indication, and further determine the verification result of whether the terminal currently refuses the information exposure according to the user indication. The verification result will be transmitted to the first network device. After receiving the verification result, the first network device determines whether to execute the ranging/SL positioning request. That is, in the embodiment corresponding to Figure 2A, if it is necessary to determine whether the terminal refuses to expose the location information at the current moment based on the user's instructions, the first network device will determine whether to perform ranging/SL positioning after obtaining the verification results of each need to determine whether the location information is refused to be exposed at the current moment based on the user's instructions.

针对隐私配置表明第m个终端接受位置信息暴露的情况下，且在第m个终端的隐私配置不包含第二指示的情况下，则不用获取用户指示第m个终端当前是否拒绝位置信息暴露的验证结果，此时单独根据隐私配置确定第m个终端是否拒绝位置信息的暴露。 In the case where the privacy configuration indicates that the mth terminal accepts exposure of location information and the privacy configuration of the mth terminal does not include a second indication, it is not necessary to obtain the verification result of the user indicating whether the mth terminal currently refuses exposure of location information. At this time, whether the mth terminal refuses exposure of location information is determined based on the privacy configuration alone.

在一些实施例中，第二指示可为隐私配置中的第二指示。第二指示，用于指示对应终端的第一指示接受位置信息暴露的情况下，需要基于用户指示进一步确定终端当前是否拒绝位置信息的暴露。In some embodiments, the second indication may be a second indication in a privacy configuration. The second indication is used to indicate that when the first indication of the corresponding terminal accepts the exposure of the location information, it is necessary to further determine whether the terminal currently refuses the exposure of the location information based on the user indication.

在一些实施例中，第三请求消息，用于获取验证结果。In some embodiments, the third request message is used to obtain a verification result.

在一些实施例中，第三请求消息包括第m个终端的标识。In some embodiments, the third request message includes an identifier of the mth terminal.

在一些实施例中，n个终端中任意的多个终端共用第三网络设备，则第一网络设备通过一条第三请求消息可以携带这多个终端的标识信息，通过一条第三请求消息触发第三网络设备进行验证并获得验证结果。In some embodiments, any multiple terminals among the n terminals share a third network device, and the first network device can carry identification information of the multiple terminals through a third request message, trigger the third network device to perform verification and obtain verification results through a third request message.

在另一些实施例中，n个终端中任意的多个终端分别对应一第三网络设备，则第一网络设备通过一条第三请求消息携带一个终端的标识信息，通过多条第三请求消息触发该终端对应的第三网络设备进行验证并获得验证结果。该验证结果可用于n个终端中拒绝位置信息暴露的终端信息的首次确定或单独确定。In other embodiments, any multiple terminals among the n terminals correspond to a third network device respectively, and the first network device carries the identification information of a terminal through a third request message, triggers the third network device corresponding to the terminal through multiple third request messages to perform verification and obtain verification results. The verification results can be used for the first determination or individual determination of the terminal information of the n terminals that refuses to expose the location information.

在一些实施例中，隐私配置单独包括第二指示而不包括第一指示的情况下，则仅仅需要根据用户指示确定终端是否拒绝位置信息的暴露。In some embodiments, when the privacy configuration includes the second indication alone but does not include the first indication, it is only necessary to determine whether the terminal refuses exposure of the location information according to the user indication.

在一些实施例中，隐私配置同时包括第一指示和第二指示的情况下，则需要在第一指示表明终端接受位置信息暴露的情况下，再需要根据用户指示确定该终端当前是否拒绝位置信息暴露。In some embodiments, when the privacy configuration includes both the first indication and the second indication, it is necessary to determine whether the terminal currently refuses location information exposure based on the user indication when the first indication indicates that the terminal accepts location information exposure.

在一些实施例中，第三网络设备可为终端的接入管理功能(Access Management Function，AMF)。不同的终端的AMF可相同或不同。In some embodiments, the third network device may be an access management function (AMF) of the terminal. The AMFs of different terminals may be the same or different.

若第三网络设备和第一网络设备位于同一个PLMN内，则第一网络设备直接向第三网络设备发送第三请求消息即可。If the third network device and the first network device are located in the same PLMN, the first network device may directly send the third request message to the third network device.

若第三网络设备和第一网络设备位于不同PLMN内，则该第一网络设备通过第三网络设备所在PLMN内的第一网络设备转发第三请求消息。If the third network device and the first network device are located in different PLMNs, the first network device forwards the third request message through the first network device in the PLMN where the third network device is located.

S2106：第三网络设备向第m个终端发送第五请求消息。S2106: The third network device sends a fifth request message to the mth terminal.

In some embodiments, the fifth request message includes query information.

在一些实施例中，该询问信息被显示在终端，可用于询问用户是否同意、拒绝或接受位置信息暴露。In some embodiments, the inquiry information is displayed on the terminal and can be used to ask the user whether to agree, refuse or accept the exposure of the location information.

在一些实施例中，验证结果包括成功结果和/或失败结果。In some embodiments, the verification result includes a success result and/or a failure result.

在一些实施例中，成功结果对应于接受位置信息暴露；失败结果对应于拒绝位置信息暴露。In some embodiments, a successful result corresponds to accepting the location information exposure; a failed result corresponds to rejecting the location information exposure.

在一些实施例中，第三网络设备在指定时长内成功接收到第五响应消息，根据用户指示确定验证结果。In some embodiments, the third network device successfully receives the fifth response message within a specified time period and determines the verification result according to the user's instructions.

例如，第三网络设备在指定时长内成功接收到第五响应消息且第五响应消息携带的用户指示表明拒绝位置信息暴露，向第一网络设备发送携带失败结果的第三响应消息。For example, the third network device successfully receives the fifth response message within the specified time period and the user instruction carried in the fifth response message indicates rejection of location information exposure, and sends a third response message carrying a failure result to the first network device.

又例如，第三网络设备在指定时长内成功接收到第五响应消息且第五响应消息携带的用户指示表明接受位置信息暴露，向第一网络设备发送携带成功结果的第三响应消息。For another example, the third network device successfully receives the fifth response message within the specified time period and the user indication carried in the fifth response message indicates acceptance of location information exposure, and sends a third response message carrying a success result to the first network device.

在一些实施例中，第三网络设备与对应终端的连接建立失败，向第一网络设备发送携带失败结果的第三响应消息；与对应终端建立的连接，用于发送第五请求消息以获取用户指示。In some embodiments, the third network device fails to establish a connection with the corresponding terminal, and sends a third response message carrying a failure result to the first network device; the connection established with the corresponding terminal is used to send a fifth request message to obtain user instructions.

例如，终端处于空闲态，则可能需要先寻呼终端以建立连接。For example, if the terminal is in an idle state, it may be necessary to page the terminal first to establish a connection.

在一些实施例中，在指定时长内未接收到对应终端的用户指示，向第一网络设备发送携带失败结果的第三响应消息。In some embodiments, if no user instruction from the corresponding terminal is received within a specified time period, a third response message carrying a failure result is sent to the first network device.

在一些实施例中，验证失败的原因包括以下指示之一：In some embodiments, the reason for the verification failure includes one of the following indications:

终端连接失败；Terminal connection failed;

终端无响应；The terminal is unresponsive;

在一些实施例中，第三响应消息会携带各终端验证失败的原因值或原因码且该原因值或原因码与对应的终端关联。如此，第一网络设备可知晓各个终端拒绝位置信息暴露的原因。In some embodiments, the third response message carries a reason value or a reason code for each terminal verification failure, and the reason value or the reason code is associated with the corresponding terminal. In this way, the first network device can know the reason why each terminal refuses to expose the location information.

在一些实施例中，第三响应消息可携带存在的验证失败都得原因，如此第一网络设备可知晓有终端拒绝位置信息暴露以及可能存在的原因，但不知晓各个终端具体的拒绝原因。In some embodiments, the third response message may carry all reasons for the existing verification failures, so that the first network device can know that a terminal refuses to expose the location information and the possible reasons, but does not know the specific reasons for the refusal of each terminal.

S2109：第一网络设备确定是否执行第一请求消息对应的测距/SL定位。S2109: The first network device determines whether to perform ranging/SL positioning corresponding to the first request message.

在一个实施例中，根据第一指示确定出n个终端中拒绝位置信息的第一个数；在隐私配置包括第二指示的情况下，根据用户指示确定n个终端中拒绝位置信息的第二个数；根据第一指示确定出n个终端中拒绝位置信息且在隐私配置包括第二指示的情况下根据用户指示确定n个终端中拒绝位置信息得到的第三个数。通常情况下，第三个数可为第一个数和第二个数的较大者。 In one embodiment, a first number of n terminals that reject location information is determined according to the first indication; if the privacy configuration includes the second indication, a second number of n terminals that reject location information is determined according to the user indication; a third number is obtained by determining the n terminals that reject location information according to the first indication and determining the n terminals that reject location information according to the user indication when the privacy configuration includes the second indication. Typically, the third number may be the larger of the first number and the second number.

在本公开实施例中，拒绝位置信息暴露的终端个数可为第一个数、第二个数或者第三个数。In the embodiment of the present disclosure, the number of terminals whose location information is refused to be exposed may be the first number, the second number or the third number.

在一些实施例中，根据拒绝位置信息暴露的终端信息，确定是否执行第一请求消息对应的测距/SL定位。In some embodiments, whether to perform ranging/SL positioning corresponding to the first request message is determined based on the terminal information that refuses to expose the location information.

在一些实施例中，根据n个终端中拒绝位置信息暴露的终端个数是否超过规则定义的个数，确定是否执行第一请求消息对应的测距/SL定位。In some embodiments, whether to execute ranging/SL positioning corresponding to the first request message is determined based on whether the number of terminals among the n terminals that refuse to expose their location information exceeds the number defined by the rule.

在一些实施例中，根据n个终端中规则限定必须参与测距/SL定位的终端是否拒绝位置信息暴露，确定是否执行第一请求消息对应的测距/SL定位。In some embodiments, whether to execute ranging/SL positioning corresponding to the first request message is determined based on whether the terminal that must participate in ranging/SL positioning according to the rules among the n terminals refuses to expose its location information.

在一些实施例中，若n个终端中拒绝位置信息暴露的终端个数超过规则定义的个数，确定不执行第一请求消息对应的测距/SL定位。In some embodiments, if the number of terminals among the n terminals that refuse to expose their location information exceeds the number defined by the rule, it is determined not to perform the ranging/SL positioning corresponding to the first request message.

在一些实施例中，若n个终端或者n-1个终端拒绝位置信息暴露，确定不执行第一请求消息对应的测距/SL定位。在这种情况下，认为测距/SL是相对测距，必须要有两个终端接受位置信息暴露才进行测距/SL定位。In some embodiments, if n terminals or n-1 terminals refuse to expose their location information, it is determined not to perform the ranging/SL positioning corresponding to the first request message. In this case, ranging/SL is considered to be relative ranging, and two terminals must accept the exposure of their location information before ranging/SL positioning is performed.

在一些实施例中，在n-1个终端拒绝位置信息暴露的情况下，根据类型信息指示的测距结果，确定是否执行测距/SL定位。In some embodiments, when n-1 terminals refuse to expose their location information, it is determined whether to perform ranging/SL positioning according to the ranging result indicated by the type information.

例如，在n-1个终端拒绝位置信息暴露的情况下，根据类型信息指示的测距结果为相对参考终端的距离和/或方向，确定执行测距/SL定位。For example, when n-1 terminals refuse to expose their location information, it is determined to perform ranging/SL positioning according to the ranging result indicated by the type information as the distance and/or direction relative to the reference terminal.

又例如，在n-1个终端拒绝位置信息暴露的情况下，根据类型信息指示的测距结果为指定终端之间的相对位置关系，确定不执行测距/SL定位。该指定终端不包含参考终端。For another example, when n-1 terminals refuse to expose their location information, it is determined not to perform ranging/SL positioning according to the relative position relationship between designated terminals indicated by the ranging result indicated by the type information. The designated terminals do not include the reference terminal.

还例如，在n-1个终端拒绝位置信息暴露的情况下，根据类型信息指示的测距结果为终端的绝对位置信息，确定继续执行测距/SL定位。For another example, when n-1 terminals refuse to expose their location information, it is determined to continue to perform ranging/SL positioning according to the ranging result indicated by the type information being the absolute location information of the terminal.

若大于或等于1且小于或等于n-2个终端拒绝位置信息暴露且规则不允许小于或等于n-2个终端拒绝位置信息暴露，停止执行第一请求消息对应的测距/SL定位；If more than or equal to 1 and less than or equal to n-2 terminals refuse to expose their location information and the rule does not allow less than or equal to n-2 terminals to refuse to expose their location information, stop executing the ranging/SL positioning corresponding to the first request message;

若大于或等于1且小于或等于n-2个终端拒绝位置信息暴露且规则指定必须参与测距的终端接受位置信息暴露，确定执行第一请求消息对应的测距/SL定位；If there are greater than or equal to 1 and less than or equal to n-2 terminals that refuse to expose their location information and the rule specifies that the terminals that must participate in ranging accept exposure of their location information, determine to perform ranging/SL positioning corresponding to the first request message;

若大于或等于1且小于或等于n-2个终端拒绝位置信息暴露且规则指定必须参与测距的终端拒绝位置信息暴露，确定不执行第一请求消息对应的测距/SL定位。If there are greater than or equal to 1 and less than or equal to n-2 terminals that refuse to expose their location information and the rule specifies that the terminals that must participate in ranging refuse to expose their location information, it is determined not to perform ranging/SL positioning corresponding to the first request message.

当然以上仅仅是确定是否执行测距/SL定位的举例说明，具体实现不局限于上述举例。Of course, the above is merely an example of determining whether to perform ranging/SL positioning, and the specific implementation is not limited to the above example.

S2110：第一网络设备向请求端发送第一响应消息。S2110: The first network device sends a first response message to the requesting end.

在一些实施例中，第一响应消息可包括成功响应消息和/或失败响应消息。In some embodiments, the first response message may include a success response message and/or a failure response message.

在一些实施例中，确定不执行第一请求消息对应的测距/SL定位请求，第一网络设备向请求端发送失败响应消息。In some embodiments, it is determined that the ranging/SL positioning request corresponding to the first request message is not to be executed, and the first network device sends a failure response message to the requesting end.

在一些实施例中，失败响应消息，指示测距/SL定位失败。In some embodiments, the failure response message indicates that ranging/SL positioning failed.

在一些实施例中，失败响应消息包括第一信息。In some embodiments, the failure response message includes first information.

在一些实施例中，第一信息用于指示测距定位失败的原因。In some embodiments, the first information is used to indicate the reason why the ranging and positioning fails.

在一些实施例中，第一信息指示以下至少之一：In some embodiments, the first information indicates at least one of the following:

规则不允许测距/SL定位；The rules do not allow ranging/SL positioning;

终端连接失败；Terminal connection failed;

终端无响应；The terminal is unresponsive;

在一些实施例中，第一信息可逐个终端指示测距/SL定位失败的原因，即第一信息将分别指示每一个终端的测距/SL定位失败的原因。In some embodiments, the first information may indicate the reason for the ranging/SL positioning failure for each terminal, that is, the first information will indicate the reason for the ranging/SL positioning failure of each terminal respectively.

在一些实施例中，第一信息不与终端关联，但是包括本次测距/SL定位失败的各种原因。In some embodiments, the first information is not associated with the terminal, but includes various reasons for the failure of the ranging/SL positioning.

失败消息携带上述信息，可由请求端根据失败原因确定是否重新发起测距/SL定位。The failure message carries the above information, and the requesting end can determine whether to re-initiate ranging/SL positioning based on the cause of the failure.

在一些实施例中，若确定执行第一请求消息对应的测距/SL定位，向请求端发送成功响应消息。In some embodiments, if it is determined to execute the ranging/SL positioning corresponding to the first request message, a success response message is sent to the requesting end.

在一些实施例中，成功响应消息包括测距定位结果。In some embodiments, the success response message includes a ranging positioning result.

在一些实施例中，若并未对所有终端执行测距/SL定位，则成功响应消息还包括以下至少之一：In some embodiments, if ranging/SL positioning is not performed for all terminals, the success response message further includes at least one of the following:

在一些实施例中，若有对所有终端测距/SL定位，则成功响应消息可不包含参与测距/SL定位的终端信息、未参与测距/SL定位的终端信息和/或，未参与测距/SL定位的终端的原因信息，从而减少信令开销。In some embodiments, if ranging/SL positioning is performed for all terminals, the success response message may not include terminal information participating in ranging/SL positioning, terminal information not participating in ranging/SL positioning, and/or reason information for terminals not participating in ranging/SL positioning, thereby reducing signaling overhead.

在一些实施例中，在需要获取用户指示确定终端当前时刻是否拒绝位置信息暴露的情况下，第一网络设备可以向根据隐私配置的第一指示确定接受位置信息暴露的第三网络设备，发送第三请求消息以触发第三网络设备获取到当前的用户指示。此时根据第一指示确定接受位置信息暴露的终端的第三网络设备可以相同或者不同。例如，有部分终端的第三网络设备与该第一网络设备位于相同的PLMN，有部分终端的第三网络设备与该第一网络设备位于不同的PLMN。第一网络设备接收到各个第三网络设备根据用户指示生成的验证结果之后，根据验证结果和规则最终确定是否发起测距/SL定位。故在这种情况下，无需第三网络设备进行是否执行测距/SL定位的判断，因此第三请求消息无需携带规则信息。In some embodiments, when it is necessary to obtain a user instruction to determine whether the terminal refuses to expose the location information at the current moment, the first A network device may send a third request message to a third network device that is determined to accept exposure of location information according to the first indication of the privacy configuration to trigger the third network device to obtain the current user indication. At this time, the third network device of the terminal that is determined to accept exposure of location information according to the first indication may be the same or different. For example, the third network devices of some terminals are located in the same PLMN as the first network device, and the third network devices of some terminals are located in a different PLMN from the first network device. After the first network device receives the verification results generated by each third network device according to the user indication, it finally determines whether to initiate ranging/SL positioning based on the verification results and the rules. Therefore, in this case, there is no need for the third network device to determine whether to perform ranging/SL positioning, so the third request message does not need to carry rule information.

图2B是根据本公开实施例示出的一种测距方法的交互示意图。如图2B所示，本公开实施例涉及测距方法，用于通信系统100。Fig. 2B is an interactive schematic diagram of a distance measurement method according to an embodiment of the present disclosure. As shown in Fig. 2B, the embodiment of the present disclosure relates to a distance measurement method, which is used in a communication system 100.

图2B所示的实施例，第一网络设备根据隐私配置的第一指示确定的拒绝位置信息暴露的终端信息直接确定是否符合执行测距/SL定位的条件。若第一网络设备确定符合执行测距/SL定位的条件，则向第三网络设备发送第四请求消息。该第四请求消息可触发第三网络设备发起测距/SL定位。第三网络设备收到第四请求消息之后，会根据终端隐私配置是否包含第二指示，进一步在终端的隐私配置包括第二指示的情况下获取终端的用户指示，并根据用户指示确定当前时刻拒绝位置信息暴露的终端信息，并进一步根据当前时刻拒绝位置信息暴露的终端信息和规则最终确定是否执行测距/SL定位策略。本公开实施例可适用于符合参加测距/SL定位条件的终端属于同一个第三网络设备的场景，此时第一网络设备仅需要向一个第三网络设备发送一条第四请求消息即可。In the embodiment shown in FIG2B , the first network device directly determines whether the conditions for performing ranging/SL positioning are met based on the terminal information that refuses location information exposure determined by the first indication of the privacy configuration. If the first network device determines that the conditions for performing ranging/SL positioning are met, a fourth request message is sent to the third network device. The fourth request message can trigger the third network device to initiate ranging/SL positioning. After receiving the fourth request message, the third network device will determine the terminal information that refuses location information exposure at the current moment based on whether the terminal privacy configuration includes the second indication, and further obtain the user indication of the terminal if the privacy configuration of the terminal includes the second indication, and determine the terminal information that refuses location information exposure at the current moment based on the user indication, and further determine whether to execute the ranging/SL positioning strategy based on the terminal information and rules that refuse location information exposure at the current moment. The disclosed embodiment can be applied to scenarios where terminals that meet the conditions for participating in ranging/SL positioning belong to the same third network device. At this time, the first network device only needs to send a fourth request message to a third network device.

在一些实施例中，若无终端拒绝位置信息暴露，确定符合执行第一请求消息对应的测距/SL定位的条件。在这种情况下可根据规则来确定，也可以直接确定执行测距/SL定位。In some embodiments, if no terminal refuses to expose the location information, it is determined that the conditions for performing the ranging/SL positioning corresponding to the first request message are met. In this case, it can be determined according to the rules, or it can be directly determined to perform the ranging/SL positioning.

在一些实施例中，若n个终端或者n-1个终端拒绝位置信息暴露，确定不符合执行第一请求消息对应的测距/SL定位的条件。在这种情况下，认为测距/SL是相对测距，必须要有两个终端接受位置信息暴露才进行测距/SL定位。In some embodiments, if n terminals or n-1 terminals refuse to expose their location information, it is determined that the conditions for performing the ranging/SL positioning corresponding to the first request message are not met. In this case, the ranging/SL is considered to be relative ranging, and two terminals must accept the exposure of their location information before performing ranging/SL positioning.

在一些实施例中，在n-1个终端拒绝位置信息暴露的情况下，根据类型信息指示的测距结果，确定是否符合执行测距/SL定位的条件。In some embodiments, when n-1 terminals refuse to expose their location information, it is determined whether the conditions for performing ranging/SL positioning are met based on the ranging result indicated by the type information.

例如，在n-1个终端拒绝位置信息暴露的情况下，根据类型信息指示的测距结果为相对参考终端的距离和/或方向，确定符合执行测距/SL定位的条件。For example, when n-1 terminals refuse to expose their location information, the ranging result indicated by the type information is the distance and/or direction relative to the reference terminal, and it is determined that the conditions for performing ranging/SL positioning are met.

又例如，n-1个终端拒绝位置信息暴露的情况下，根据类型信息指示的测距结果为指定终端之间的相对位置关系，确定符合不执行测距/SL定位的条件。该指定终端不包含参考终端。For another example, when n-1 terminals refuse to expose their location information, the ranging result indicated by the type information is the relative position relationship between the designated terminals, and it is determined that the condition of not performing ranging/SL positioning is met. The designated terminals do not include the reference terminal.

还例如，n-1个终端拒绝位置信息暴露的情况下，根据类型信息指示的测距结果为终端的绝对位置信息，确定继续执行测距/SL定位。For another example, when n-1 terminals refuse to expose their location information, the ranging result indicated by the type information is the absolute location information of the terminal, and it is determined to continue to perform ranging/SL positioning.

在一些实施例中，若n个终端中规则限定必须参与测距/SL定位的终端是否拒绝位置信息暴露，确定是否符合执行第一请求消息对应的测距/SL定位的条件。In some embodiments, if the rules among the n terminals stipulate whether the terminal that must participate in ranging/SL positioning refuses to expose its location information, it is determined whether the conditions for executing the ranging/SL positioning corresponding to the first request message are met.

在一些实施例中，若大于或等于1且小于或等于n-2个终端拒绝位置信息暴露，根据规则确定是否符合执行第一请求消息对应的测距/SL定位的条件，还包括以下至少之一：In some embodiments, if greater than or equal to 1 and less than or equal to n-2 terminals refuse to expose the location information, determining whether the condition for performing the ranging/SL positioning corresponding to the first request message is met according to the rule, further includes at least one of the following:

若大于或等于1且小于或等于n-2个终端拒绝位置信息暴露，且规则允许小于或等于n-2个终端拒绝位置信息暴露，确定符合执行第一请求消息对应的测距/SL定位的条件； If the number of terminals greater than or equal to 1 and less than or equal to n-2 refuses to expose the location information, and the rule allows less than or equal to n-2 terminals to refuse to expose the location information, it is determined that the conditions for performing the ranging/SL positioning corresponding to the first request message are met;

若大于或等于1且小于或等于n-2个终端拒绝位置信息暴露且规则不允许小于或等于n-2个终端拒绝位置信息暴露，确定不符合执行第一请求消息对应的测距/SL定位的条件；If the number of terminals greater than or equal to 1 and less than or equal to n-2 refuses to expose the location information and the rule does not allow the number of terminals less than or equal to n-2 to refuse to expose the location information, it is determined that the conditions for performing the ranging/SL positioning corresponding to the first request message are not met;

若大于或等于1且小于或等于n-2个终端拒绝位置信息暴露且规则指定必须参与测距的终端接受位置信息暴露，确定符合执行第一请求消息对应的测距/SL定位的条件；If greater than or equal to 1 and less than or equal to n-2 terminals refuse to expose their location information and the rule specifies that the terminals that must participate in ranging accept exposure of their location information, it is determined that the conditions for performing ranging/SL positioning corresponding to the first request message are met;

若大于或等于1且小于或等于n-2个终端拒绝位置信息暴露且规则指定必须参与测距的终端拒绝位置信息暴露，确定不符合执行第一请求消息对应的测距/SL定位的条件。If the number of terminals greater than or equal to 1 and less than or equal to n-2 refuses to expose the location information and the rule specifies that the terminals that must participate in ranging refuse to expose the location information, it is determined that the conditions for executing the ranging/SL positioning corresponding to the first request message are not met.

当然以上仅仅是确定是否符合执行测距/SL定位的条件的举例说明，具体实现不局限于上述举例。Of course, the above is merely an example of determining whether the conditions for performing ranging/SL positioning are met, and the specific implementation is not limited to the above example.

S2306：第一网络设备向第三网络设备发送第四请求消息。S2306: The first network device sends a fourth request message to the third network device.

In some embodiments, the reference terminal is a terminal specified by the requesting end, and the distance and/or direction of the measured terminal (or target terminal) relative to the reference terminal can be measured by ranging/SL positioning. In some cases, the location information of the reference terminal is known.

在一些实施例中，第四请求消息会携带指示信息，该指示信息，用于第三网络设备获取用户指示的终端。该指示信息可为符合测距/SL定位的条件的终端中需要用户指示的标识信息。In some embodiments, the fourth request message may carry indication information, which is used by the third network device to obtain the terminal indicated by the user. The indication information may be identification information of the terminal that meets the ranging/SL positioning conditions and requires user indication.

在一些实施例中，第一网络设备确定X个终端对应的第三网络设备相同，则第一网络设备直接向第三网络设备发送第四请求消息，而非是图2A对应实施例的第三请求消息。In some embodiments, if the first network device determines that the third network devices corresponding to the X terminals are the same, the first network device directly sends a fourth request message to the third network device instead of the third request message of the embodiment corresponding to FIG. 2A .

在一些实施例中，第一网络设备和第三网络设备可位于同一个PLMN中也可以位于不同的PLMN中。当第一网络设备和第三网络设备位于不同的PLMN时，第一网络设备通过第三网络设备所在PLMN的第一网络设备的信息转发或透传，与第三网络设备进行信息交互。In some embodiments, the first network device and the third network device may be located in the same PLMN or in different PLMNs. When the first network device and the third network device are located in different PLMNs, the first network device exchanges information with the third network device through information forwarding or transparent transmission of the first network device of the PLMN where the third network device is located.

在一些实施例中，第m个终端的隐私配置不包含第二指示的情况下，可确定第m个终端接受位置信息暴露，无需从第m个终端获取用户指示。In some embodiments, when the privacy configuration of the mth terminal does not include the second indication, it can be determined that the mth terminal accepts the exposure of the location information without obtaining a user indication from the mth terminal.

S2308：第三网络设备根据获取的用户指示得到验证结果。S2308: The third network device obtains a verification result according to the acquired user instruction.

在一些实施例中，第三网络设备获取到Y个终端的用户指示之后，根据Y个终端的用户指示，生成验证结果。In some embodiments, after the third network device obtains the user instructions of the Y terminals, it generates a verification result according to the user instructions of the Y terminals.

Y是参与测距/SL定位终端中隐私配置包含第二指示的终端个数。Y可为小于或等于X的正整数。Y is the number of terminals participating in ranging/SL positioning whose privacy configuration includes the second indication. Y can be a positive integer less than or equal to X.

在Y等于0的情况下，则可以跳过步骤S2306直接生成成功结果。When Y is equal to 0, step S2306 can be skipped to directly generate a successful result.

在一些实施例中，第m个终端的用户指示表明拒绝位置信息暴露，验证结果为失败结果，和/或，第m个终端的用户指示表明接受位置信息暴露，验证结果为成功结果，和/或，第m个终端位于网络覆盖范围外，验证结果为失败结果，和/或，在指定时长内未获取到第m个终端的用户指示，验证结果为失败结果，和/或，第三网络设备与第m个终端的连接建立失败，验证结果为失败结果。In some embodiments, the user indication of the mth terminal indicates rejection of location information exposure, and the verification result is a failure result, and/or, the user indication of the mth terminal indicates acceptance of location information exposure, and the verification result is a success result, and/or, the mth terminal is outside the network coverage, and the verification result is a failure result, and/or, the user indication of the mth terminal is not obtained within the specified time period, and the verification result is a failure result, and/or, the connection establishment between the third network device and the mth terminal fails, and the verification result is a failure result.

S2309：第三网络设备触发测距/SL定位测距以获得测距定位结果。S2309: The third network device triggers ranging/SL positioning ranging to obtain a ranging and positioning result.

在一些实施例中，第三网络设备可使用相关的测距/SL定位流程执行测距/SL定位。In some embodiments, the third network device may perform ranging/SL positioning using related ranging/SL positioning procedures.

在一些实施例中，第四响应消息可为拒绝消息。In some embodiments, the fourth response message may be a rejection message.

在一些实施例中，验证结果指示超过规则定义个数终端拒绝位置信息暴露，向第一网络设备发送拒绝消息。In some embodiments, the verification result indicates that the number of terminals exceeding the number defined by the rule refuses to expose the location information, and a rejection message is sent to the first network device.

在另一些实施例中，验证结果指示规则要求必须参与测距/SL定位的终端拒绝位置信息暴露，向第一网络设备发送拒绝消息。In other embodiments, the verification result indicates that the rule requires the terminal that must participate in ranging/SL positioning to refuse exposure of location information and send a rejection message to the first network device.

在一些实施例中，在一些实施例中，拒绝消息指示拒绝测距/SL定位。In some embodiments, in some embodiments, the rejection message indicates rejection of ranging/SL positioning.

在一些实施例中，拒绝消息还包括第三信息。第三信息指示拒绝测距/SL定位的原因。In some embodiments, the rejection message further includes third information. The third information indicates the reason for rejecting ranging/SL positioning.

在一些实施例中，第四响应消息可为成功消息。In some embodiments, the fourth response message may be a success message.

在一些实施例中，成功消息至少包括测距定位结果。In some embodiments, the success message includes at least a ranging and positioning result.

在一些实施例中，成功消息还包括以下至少之一：In some embodiments, the success message further includes at least one of the following:

在一些实施例中，X个终端均参与了测距/SL定位，则成功消息可不包含参与测距/SL定位的终端信息、未参与测距/SL定位的终端信息和/或未参与测距/SL定位的终端的原因信息，从而节省信令开销。In some embodiments, if all X terminals participate in ranging/SL positioning, the success message may not include information about terminals participating in ranging/SL positioning, information about terminals not participating in ranging/SL positioning, and/or reason information about terminals not participating in ranging/SL positioning, thereby saving signaling overhead.

在一些实施例中，少于X个终端参与了测距/SL定位，则成功消息可包含参与测距/SL定位的终端信息、未参与测距/SL定位的终端信息和/或未参与测距/SL定位的终端的原因信息，从而节省信令开销。In some embodiments, if fewer than X terminals participate in ranging/SL positioning, the success message may include information about terminals participating in ranging/SL positioning, information about terminals not participating in ranging/SL positioning, and/or reason information about terminals not participating in ranging/SL positioning, thereby saving signaling overhead.

第一响应消息的具体内容可参见图2A对应实施例的S2110的相关描述。For specific content of the first response message, please refer to the relevant description of S2110 of the embodiment corresponding to Figure 2A.

在本公开实施例中，第一网络设备根据隐私配置的第一指示确定出符合测距/SL定位的条件下，就向第三网络设备发送第四请求消息，以触发第三网络设备发起测距/SL定位测量。通常情况下，根据隐私配置的第一指示接受位置信息暴露的X终端可归属同一个第三网络设备。在这种情况下，第四请求消息可携带有用于第三网络设备根据验证结果最终确定是否执行测距/SL定位的规则，以方便第三网络设备基于规则最终确定是否执行测距/SL定位。In the disclosed embodiment, when the first network device determines that the conditions for ranging/SL positioning are met according to the first indication of the privacy configuration, the first network device sends a fourth request message to the third network device to trigger the third network device to initiate ranging/SL positioning measurement. Generally, the X terminal that accepts the exposure of location information according to the first indication of the privacy configuration can belong to the same third network device. In this case, the fourth request message may carry a rule for the third network device to finally determine whether to perform ranging/SL positioning based on the verification result, so as to facilitate the third network device to finally determine whether to perform ranging/SL positioning based on the rule.

如图3A所示，本公开实施例提供一种测距方法，由第一网络设备执行。As shown in FIG. 3A , an embodiment of the present disclosure provides a ranging method, which is executed by a first network device.

图3A所示的实施例与图2A所示的实施例相关。在有需要基于用户指示的验证结果确定最终拒绝位置信息的终端信息的情况下，第一网络设备会向通过第三请求信息触发第三网络设备获取用户指示以及验证结果，在获取到所有终端的验证结果之后，根据所需获得所有验证结果之后，由第一网络设备根据规则最终确定是否执行测距/SL定位。当然第一网络设备也可以单独根据隐私配置中的第一指示确定是否执行测距/SL定位，而无需获取用户指示的验证结果来最终确定是否执行测距/SL定位结果。The embodiment shown in FIG3A is related to the embodiment shown in FIG2A. In the case where it is necessary to determine the terminal information for the final rejection of the location information based on the verification result indicated by the user, the first network device will trigger the third network device through the third request information to obtain the user instruction and the verification result. After obtaining the verification results of all terminals, after obtaining all the verification results as required, the first network device will finally determine whether to perform ranging/SL positioning according to the rules. Of course, the first network device can also determine whether to perform ranging/SL positioning based on the first indication in the privacy configuration alone, without obtaining the verification result indicated by the user to finally determine whether to perform ranging/SL positioning results.

具体地，本公开实施例提供的测距方法可包括：Specifically, the ranging method provided by the embodiment of the present disclosure may include:

S3101：第一网络设备接收第一请求消息。S3101: The first network device receives a first request message.

在一些实施例中，第一网络设备接收请求端发送的第一请求消息。In some embodiments, the first network device receives a first request message sent by the requester.

在一些实施例中，第一请求消息，用于请求n个终端的测距/侧行链路SL定位。 In some embodiments, the first request message is used to request ranging/sidelink SL positioning of n terminals.

在一些实施例中，n是大于或等于2的正整数。In some embodiments, n is a positive integer greater than or equal to 2.

第一网络设备接收请求端的可选实施例都可以参见图2A对应实施例S2101。For optional embodiments of the first network device receiving the request end, please refer to the corresponding embodiment S2101 of Figure 2A.

在一些实施例中，第一网络设备可为GMLC。In some embodiments, the first network device may be a GMLC.

S3102：第一网络设备确定n个终端中拒绝位置信息暴露的终端信息。S3102: The first network device determines terminal information of n terminals that refuse to have their location information exposed.

在一些实施例中，确定n个终端中拒绝位置信息暴露的终端信息。该终端信息可包括终端个数和/或终端标识。In some embodiments, information of terminals that refuse to expose location information among n terminals is determined. The terminal information may include the number of terminals and/or terminal identifiers.

在一些实施例中，第一网络设备确定n个终端中拒绝位置信息暴露的终端个数可采用如下方式的至少其中之一：In some embodiments, the first network device may determine the number of terminals among the n terminals that refuse to expose their location information by using at least one of the following methods:

方式1：第一网络设备根据n个终端的隐私配置的第一指示，确定n个终端中拒绝位置信息暴露的终端。Mode 1: The first network device determines a terminal among the n terminals that refuses to expose its location information according to a first indication of the privacy configuration of the n terminals.

在一些实施例中，第一指示，单独指示对应终端是否拒绝暴露位置信息。In some embodiments, the first indication separately indicates whether the corresponding terminal refuses to expose the location information.

在另一些实施例中，第一指示，指示对应终端接受位置信息的条件，在不满足条件的情况下可认为终端拒绝位置信息的暴露。In some other embodiments, the first indication indicates a condition for the corresponding terminal to accept the location information. If the condition is not met, it can be considered that the terminal refuses to expose the location information.

此时，第一网络设备可从第二网络设备获取各个终端的隐私配置。第二网络设备可为UDM。At this time, the first network device may obtain the privacy configuration of each terminal from the second network device. The second network device may be a UDM.

在一些实施例中，隐私配置可作为终端的签约数据的组成部分。In some embodiments, the privacy configuration may be a component of the subscription data of the terminal.

在另一些实施例中，第一网络设备还可以从第二网络设备基于隐私配置返回的验证指示，该验证指示至少基于隐私配置中的第一指示确定的对应终端是否拒绝位置信息暴露。In some other embodiments, the first network device may also receive a verification indication returned by the second network device based on the privacy configuration, where the verification indication is at least based on whether the corresponding terminal determines based on the first indication in the privacy configuration whether to refuse location information exposure.

方式2：Method 2:

第一网络设备基于第m个终端的用户指示确定第m个终端是否拒绝位置信息暴露，并统计n个终端中拒绝位置信息暴露的终端。The first network device determines whether the mth terminal refuses location information exposure based on a user instruction of the mth terminal, and counts the terminals that refuse location information exposure among the n terminals.

在一些实施例中，第一网络设备在第m个终端的隐私配置包含第二指示时，基于第m个终端的用户指示确定第m个终端是否拒绝位置信息暴露。In some embodiments, when the privacy configuration of the mth terminal includes the second indication, the first network device determines whether the mth terminal refuses location information exposure based on a user indication of the mth terminal.

在另一些实施例中，第一网络设备也可以根据本地配置信息和/或运营商策略，基于第m个终端的用户指示确定第m个终端是否拒绝位置信息暴露。此处的m是小于或等于n的正整数。In some other embodiments, the first network device may also determine whether the mth terminal refuses location information exposure based on the user instruction of the mth terminal according to local configuration information and/or operator policy. Here, m is a positive integer less than or equal to n.

在需要基于第m个终端的用户指示确定第m个终端是否拒绝位置信息暴露的情况下，第一网络设备向第m个终端的第三网络设备发送第三请求消息。In a case where it is necessary to determine whether the mth terminal refuses location information exposure based on a user instruction of the mth terminal, the first network device sends a third request message to a third network device of the mth terminal.

在一些实施例中，第三请求消息用于获取验证结果。如此，第一网络设备会接收到第三网络设备基于第三请求消息返回的第三响应消息。In some embodiments, the third request message is used to obtain the verification result. In this way, the first network device will receive a third response message returned by the third network device based on the third request message.

在一些实施例中，第三响应消息包括验证结果。该验证结果，指示第m个终端的用户指示表明第m个终端的是否拒绝位置信息暴露。In some embodiments, the third response message includes a verification result, wherein the verification result indicates whether the user of the mth terminal indicates whether the mth terminal refuses to expose the location information.

在一些实施例中，验证结果包括成功结果和/或失败结果；成功结果对应于接受位置信息暴露；失败结果对应于拒绝位置信息暴露。In some embodiments, the verification result includes a success result and/or a failure result; a success result corresponds to accepting the location information exposure; a failure result corresponds to rejecting the location information exposure.

方式3：Method 3:

第一网络设备根据n个终端的隐私配置的第一指示确定n个终端中拒绝位置信息暴露的终端。 The first network device determines a terminal among the n terminals that refuses to expose location information according to the first indication of the privacy configuration of the n terminals.

在第m个终端的隐私配置包括第二指示且在根据第m个终端隐私配置的第一指示允许第m个终端暴露隐私的情况下，基于第m个终端的用户指示确定第m个终端是否拒绝位置信息暴露。When the privacy configuration of the mth terminal includes a second indication and the mth terminal is allowed to expose privacy according to the first indication of the privacy configuration of the mth terminal, it is determined whether the mth terminal refuses location information exposure based on a user indication of the mth terminal.

在这种方式可能存在n-a-b个终端接受位置信息暴露，其中，a可为根据第一指示确定拒绝位置信息暴露的终端个数，b可为第一指示允许位置信息暴露的情况下基于用户指示拒绝位置信息暴露的个数。在这种情况下，则n个终端中拒绝位置信息暴露的终端个数可为a+b。In this way, there may be n-a-b terminals that accept location information exposure, where a may be the number of terminals that refuse location information exposure according to the first indication, and b may be the number of terminals that refuse location information exposure based on user instructions when the first indication allows location information exposure. In this case, the number of terminals that refuse location information exposure among the n terminals may be a+b.

在方式3中，第一网络设备可以通过与第三网络设备之间的第三请求消息和第三响应消息的交互，可以实现获取到第m个终端用户指示的验证结果。In mode 3, the first network device can obtain the verification result indicated by the mth terminal user through the interaction of the third request message and the third response message between the first network device and the third network device.

在本实施例中，第一网络设备可以根据需要或者根据规则，选择上述任意一种方式确定n个终端中拒绝位置信息暴露的终端个数。In this embodiment, the first network device may select any of the above methods to determine the number of terminals that refuse to expose location information among the n terminals according to needs or rules.

S3103：第一网络设备确定是否执行第一请求消息对应的测距/SL定位。S3103: The first network device determines whether to perform ranging/SL positioning corresponding to the first request message.

在另一些实施例中，确定是否执行第一请求消息对应的测距/SL定位的可选实施方式可参见图2A对应实施例的相关部分。In other embodiments, an optional implementation method for determining whether to perform ranging/SL positioning corresponding to the first request message may refer to the relevant part of the embodiment corresponding to FIG. 2A .

在本公开实施例中，该步骤S3103的可选实施方式可参见图2A对应实施例S2109。In the embodiment of the present disclosure, the optional implementation of step S3103 can be found in the corresponding embodiment S2109 of FIG. 2A .

S3104：第一网络设备发送第一响应消息。S3104: The first network device sends a first response message.

在一些实施例中，第一网络设备向请求端发送第一响应消息。In some embodiments, the first network device sends a first response message to the requester.

在确定不执行测距/SL定位的情况下，第一网络设备向请求端发送失败响应消息。In the case of determining not to perform ranging/SL positioning, the first network device sends a failure response message to the requesting end.

在确定执行测距/SL定位的情况下，第一网络设备向请求端发送成功响应消息。When determining to perform ranging/SL positioning, the first network device sends a success response message to the requesting end.

规则不允许测距/SL定位；The rules do not allow ranging/SL positioning;

终端连接失败；Terminal connection failed;

终端无响应；The terminal is unresponsive;

在一些实施例中，第一信息可是终端粒度，指示每一个终端的测距/SL定位失败的原因。In some embodiments, the first information may be terminal granularity, indicating the reason why the ranging/SL positioning of each terminal fails.

在一些实施例中，成功响应消息包括测距定位结果。 In some embodiments, the success response message includes a ranging positioning result.

值得注意的是：在确定执行测距/SL定位的情况下，可以省略成功响应消息的发送，第一网络设备可以直接发起测距/SL定位，如此在获得测距定位结果之后将定位测距结果返回给请求端，从而减少第一网络设备和请求端之间的交互的消息数量。若有部分终端未参与测距/SL定位，可以将参与或未参与测距/SL定位的终端信息和测距定位结果一起返回给终端。It is worth noting that: in the case of determining to perform ranging/SL positioning, the sending of the success response message can be omitted, and the first network device can directly initiate ranging/SL positioning, so that after obtaining the ranging positioning result, the positioning ranging result is returned to the requesting end, thereby reducing the number of interactive messages between the first network device and the requesting end. If some terminals do not participate in ranging/SL positioning, the terminal information participating or not participating in ranging/SL positioning can be returned to the terminal together with the ranging positioning result.

在这种实施例中，在有需要基于用户指示的验证结果最终确定是否执行测距/SL定位结果的情况下，第一网络设备会从一个或多个第三网络设备接收到验证结果之后确定是否执行测距/SL定位，只有确定执行测距/SL定位的情况下，向第三网络设备发送触发测距/SL定位执行的请求消息。In this embodiment, when it is necessary to finally determine whether to execute ranging/SL positioning results based on the verification results indicated by the user, the first network device will determine whether to execute ranging/SL positioning after receiving the verification results from one or more third network devices. Only when it is determined to execute ranging/SL positioning, a request message to trigger the execution of ranging/SL positioning is sent to the third network device.

如图3B所示，本公开实施例提供一种测距方法，由第一网络设备执行。As shown in FIG. 3B , an embodiment of the present disclosure provides a ranging method, which is executed by a first network device.

图3B所示的测距方法可对应于图2B所示的实施例。第一网络设备可根据终端的隐私配置中第一指示确定符合是否执行测距/SL定位的条件。在符合测距/SL定位的条件的情况下，第一网络设备发送第四请求消息以触发测距/SL定位的执行。在一些实施例中第四请求消息可包括供第三网络设备等其他网络设备判断最终是否执行测距/SL定位的规则。The ranging method shown in FIG3B may correspond to the embodiment shown in FIG2B. The first network device may determine whether the conditions for performing ranging/SL positioning are met according to the first indication in the privacy configuration of the terminal. When the conditions for ranging/SL positioning are met, the first network device sends a fourth request message to trigger the execution of ranging/SL positioning. In some embodiments, the fourth request message may include rules for other network devices such as the third network device to determine whether to finally perform ranging/SL positioning.

如图3B所示，该测距方法可包括：As shown in FIG3B , the ranging method may include:

S3201：第一网络设备接收第一请求消息。S3201: The first network device receives a first request message.

S3202：第一网络设备根据隐私配置确定n个终端中拒绝位置信息暴露的终端信息。S3202: The first network device determines terminal information of n terminals that refuses to expose location information according to the privacy configuration.

在一些实施例中，根据隐私配置的第一指示，确定n个终端中拒绝位置信息暴露的终端信息。In some embodiments, according to the first indication of the privacy configuration, terminal information of the n terminals that refuses to expose location information is determined.

使得GMLC可通知服务请求端(例如AF/NF)接受或被拒绝的参与测距的终端。This allows the GMLC to notify the service requesting end (eg AF/NF) of the terminals participating in ranging that are accepted or rejected.

当服务被拒绝时，GMLC能够告知服务请求端(如AF/NF)实际原因。When a service is denied, the GMLC can inform the service requester (eg, AF/NF) of the actual reason.

在SL-MT-LR过程中，允许LCS客户端或AF/NF获取超过两个终端的测距/SL定位结果。GLMC确定这些终端的角色，这些UE的角色可包括：目标终端和参考终端等。且测距/SL定位结果可包括绝对位置、相对位置、终端之间的距离和/或方向等。In the SL-MT-LR process, the LCS client or AF/NF is allowed to obtain ranging/SL positioning results of more than two terminals. The GLMC determines the roles of these terminals, which may include: target terminal and reference terminal, etc. And the ranging/SL positioning results may include absolute position, relative position, distance and/or direction between terminals, etc.

方案1：Scenario 1:

如图6A所示，本公开实施例提供一种测距方法可包括：As shown in FIG6A , the present disclosure provides a ranging method which may include:

步骤1：LCS客户端或AF(通过NEF)向(H)GMLC发送LCS服务请求，以获取n个终端的测距/SL定位结果。该请求可能包括所需的QoS、所需的定位结果类型信息以及参考终端的信息。Step 1: The LCS client or AF (via NEF) sends an LCS service request to the (H)GMLC to obtain the ranging/SL positioning results of n terminals. The request may include the required QoS, the required positioning result type information, and the reference terminal information.

定位结果类型的信息可包括但不限于：与终端相关的绝对位置、相对位置或距离和/或方向。该要求亦可包括有关处理n个终端的规则，例如n个终端必须全部参与测距/SL定位，或允许n个终端的一部分被排除在测距/SL定位之外，等等。具体的规则可以根据业务需求而有所不同。The information of the positioning result type may include, but is not limited to: absolute position, relative position or distance and/or direction related to the terminal. The requirement may also include rules for handling n terminals, such as all n terminals must participate in ranging/SL positioning, or allow part of the n terminals to be excluded from ranging/SL positioning, etc. The specific rules may vary according to business needs.

在一些实施例中，该LCS服务请求还可包括：规则。示例性地，该规则可规定n个终端都必须参与测距，或部分终端可参与出测距。具体的规则可以根据服务需求而异。图6A中的UE就是终端，图6A中的UE1至UEn就是终端1至终端n。In some embodiments, the LCS service request may further include: rules. For example, the rule may specify that all n terminals must participate in ranging, or some terminals may participate in ranging. The specific rules may vary according to service requirements. The UE in FIG. 6A is a terminal, and UE1 to UEn in FIG. 6A are terminals 1 to n.

步骤2：GMLC向UDM发送Nudm-SDM-Get服务操作，以同时获取多个终端的隐私设置。UDM将返回终端的隐私设置给GMLC。GMLC将验证终端的LCS隐私配置。Step 2: GMLC sends Nudm-SDM-Get service operation to UDM to obtain the privacy settings of multiple terminals at the same time. UDM will return the privacy settings of the terminal to GMLC. GMLC will verify the LCS privacy configuration of the terminal.

如果n或n-1个终端没有被授权暴露位置信息，GMLC将确定停止服务且向LCS客户端或AF返回拒绝消息。在该拒绝消息中携带有失败原因。该失败原因可包括但不限于位置拒绝暴露位置信息等。这n或n-1个终端没有被授权暴露位置信息，即这n或n-1个终端拒绝暴露位置信息。If n or n-1 terminals are not authorized to expose location information, GMLC will determine to stop the service and return a rejection message to the LCS client or AF. The rejection message carries the failure reason. The failure reason may include but is not limited to the location rejection to expose location information. The n or n-1 terminals are not authorized to expose location information, that is, the n or n-1 terminals refuse to expose location information.

如果小于或等于n-2个终端没有被授权暴露位置信息，GMLC将根据本地规则确定是否继续执行该流程。如果规则允许，GMLC会进入步骤3。如果规则不允许，则GMLC将停止执行该流程，且向LCS客户端或者AF发送拒绝消息。该拒绝消息包括失败原因。该失败原因可包括但不限于位置拒绝暴露位置信息等。If less than or equal to n-2 terminals are not authorized to expose location information, GMLC will determine whether to continue the process based on local rules. If the rules allow, GMLC will proceed to step 3. If the rules do not allow, GMLC will stop executing the process. And send a rejection message to the LCS client or AF. The rejection message includes the failure reason. The failure reason may include but is not limited to the location rejection to expose the location information.

本地规则可由测距/SL定位应用或运营商提供或定义。如果是由测距/SL定位应用提供，GMLC可以从PCF或者NEF获取该规则。该规则可被运营商配置在PCF或者NEF上。当然PCF或NEF也可以从AF接收规则。该规则可以在步骤1中接收，或者通过其他步骤来接收。Local rules can be provided or defined by ranging/SL positioning applications or operators. If provided by ranging/SL positioning applications, GMLC can obtain the rules from PCF or NEF. The rules can be configured by the operator on PCF or NEF. Of course, PCF or NEF can also receive rules from AF. The rules can be received in step 1 or received through other steps.

步骤3：如果隐私配置具有隐私通知或隐私验证的指示符，则GMLC将向参与测距的各个终端对应的UDM发起Nudm-UECM_Get服操作。Step 3: If the privacy configuration has an indicator of privacy notification or privacy verification, the GMLC will initiate a Nudm-UECM_Get service operation to the UDM corresponding to each terminal participating in the ranging.

步骤4：GMLC向参与测距的终端的服务AMF发起Namf-Location-Notification服务操作，以请求m个终端的通知结果。Step 4: GMLC initiates the Namf-Location-Notification service operation to the serving AMF of the terminals participating in ranging to request the notification results of m terminals.

步骤5：服务AMF向终端发起NAS通知。Step 5: The service AMF initiates a NAS notification to the terminal.

步骤6：如果m个终端中有部分终端没有获得位置信息暴露的授权，或者有一些终端位于网络覆盖范围外使得服务AMF无法和终端建立NAS连接，服务AMF将向GMLC返回通知结果。该通知结果可指示失败原因。该失败原因可包括但不限于：位置拒绝或者信令连接失败等。Step 6: If some of the m terminals do not obtain authorization to disclose location information, or some terminals are located outside the network coverage so that the serving AMF cannot establish a NAS connection with the terminal, the serving AMF will return a notification result to the GMLC. The notification result may indicate the cause of the failure. The cause of the failure may include, but is not limited to, location rejection or signaling connection failure.

如果服务AMF与终端的信令连接建立失败，或部分终端在预设时长内没有回复，服务AMF将向GMLC指示失败。该失败原因可包括无响应。If the signaling connection between the serving AMF and the terminal fails to be established, or some terminals do not respond within a preset time, the serving AMF will indicate the failure to the GMLC. The failure reason may include no response.

GMLC在接受到所有服务AMF的通知结果之后，GMLC将根据规则检测是否继续流程。After receiving the notification results from all service AMFs, GMLC will check whether to continue the process according to the rules.

如果规则允许，则GMLC执行步骤7；If the rules allow, the GMLC executes step 7;

如果规则不允许，GMLC将停止该流程的执行，且向LCS客户端或AF返回失败消息。该拒绝消息可包括失败原因。该失败原因可包括但不限于：拒绝暴露位置、被规则拒绝等。在一些实施例中，该拒绝消息还可包括：拒绝暴露位置信息的终端清单、位于网络覆盖范围内的终端等。可选地，拒绝消息可包括多种失败原因。例如，失败原因可包括：各终端的拒绝消息。例如，终端1拒绝位置暴露，终端2的连接失败、终端3无用户响应。If the rules do not allow, the GMLC will stop the execution of the process and return a failure message to the LCS client or AF. The rejection message may include the reason for the failure. The reason for the failure may include, but is not limited to: refusal to expose the location, rejection by rules, etc. In some embodiments, the rejection message may also include: a list of terminals that refuse to expose location information, terminals within the network coverage, etc. Optionally, the rejection message may include multiple reasons for failure. For example, the failure reason may include: a rejection message from each terminal. For example, terminal 1 refuses location exposure, terminal 2 fails to connect, and terminal 3 has no user response.

步骤7：GMLC选择发起测距/SL定位的终端，并向终端的服务AMF发起Namf-Location-ProvidePositioningInfo服务操作，以请求n-i个终端的位置信息，i为因为没有授权或者没有隐私确认响应排除的终端个数。Step 7: GMLC selects the terminal to initiate ranging/SL positioning, and initiates the Namf-Location-ProvidePositioningInfo service operation to the terminal's service AMF to request the location information of n-i terminals, where i is the number of terminals excluded due to lack of authorization or privacy confirmation response.

步骤8：如果终端处于连接管理(Connected Management，CM)空闲态，AMF发起网络触发的服务请求以建立与终端之间的信令连接。Step 8: If the terminal is in the Connected Management (CM) idle state, AMF initiates a network-triggered service request to establish a signaling connection with the terminal.

如果信令连接建立失败，则AMF通知GMLC失败，且告知GMLC失败原因，该失败原因可为信令连接失败。(V)GMLC可向(H)GMLC发送Ngmlc-Location-Provide Location响应。该响应可包括失败原因。基于失败原因，GMLC可重新选择相互测距的两个终端，且重复执行步骤8或者向LCS客户端或AF返回拒绝消息。该拒绝消息可包括拒绝原因。该拒绝原因可包括：连接失败。If the signaling connection establishment fails, the AMF notifies the GMLC of the failure and informs the GMLC of the failure reason, which may be a signaling connection failure. (V)GMLC may send a Ngmlc-Location-Provide Location response to (H)GMLC. The response may include the failure reason. Based on the failure reason, the GMLC may reselect two terminals for mutual ranging and repeat step 8 or return a rejection message to the LCS client or AF. The rejection message may include the rejection reason. The rejection reason may include: connection failure.

步骤9-19可是常规的测距/SL定位流程，涉及的步骤可参见图6A，AMF、接入网(例如，新一代接入网(NG-RAN))。Steps 9-19 may be conventional ranging/SL positioning procedures, and the steps involved may be referred to in FIG. 6A , AMF, access network (eg, next generation access network (NG-RAN)).

步骤20：当在LCF服务响应中暴露测距/SL测距结果时，GMLC将通知LCS客户端或AF实际参与测距的终端的信息。具体可包括：在响应中指示参与测距的终端和/或未参与测距的终端。Step 20: When the ranging/SL ranging result is exposed in the LCF service response, the GMLC will notify the LCS client or AF actual The information of the terminals participating in the ranging may specifically include: indicating the terminals participating in the ranging and/or the terminals not participating in the ranging in the response.

方案2：Scenario 2:

如图6B所示，本公开实施例提供一种测距方法可包括：As shown in FIG6B , the present disclosure provides a ranging method which may include:

步骤S1：LCS客户端或AF(通过NEF)向(H)GMLC发送LCS服务请求，以获取n个终端的测距/SL定位结果。该请求可能包括所需的QoS、所需的定位结果类型信息以及参考终端的信息。Step S1: The LCS client or AF (via NEF) sends an LCS service request to the (H)GMLC to obtain the ranging/SL positioning results of n terminals. The request may include the required QoS, the required positioning result type information, and the reference terminal information.

定位结果类型的信息可包括但不限于：与终端相关的绝对位置、相对位置或相对于参考终端的距离和/或方向。该要求也可包括有关处理n个终端的规则。例如n个终端必须全部参与测距/SL定位，或允许n个终端的一部分被排除在测距/SL定位之外等等。具体的规则可以根据业务需求而有所不同。图6B中的UE就是终端，图6B中的UE1至UEn就是终端1至终端n。The information of the positioning result type may include but is not limited to: the absolute position, relative position or distance and/or direction relative to the reference terminal related to the terminal. The requirement may also include rules for processing n terminals. For example, all n terminals must participate in ranging/SL positioning, or a part of the n terminals may be excluded from ranging/SL positioning, etc. The specific rules may vary according to business requirements. The UE in Figure 6B is the terminal, and UE1 to UEn in Figure 6B are terminals 1 to terminal n.

在一些实施例中，该LCS服务请求还可包括：规则。该规则也可以称之为处理规则。In some embodiments, the LCS service request may further include: a rule. The rule may also be referred to as a processing rule.

示例性地，该规则可规定N个终端都必须参与测距，或部分终端可参与出测距。具体的规则可以根据服务需求而异。Exemplarily, the rule may stipulate that all N terminals must participate in ranging, or some terminals may participate in ranging. The specific rule may vary according to service requirements.

步骤S2：GMLC向UDM发送Nudm-SDM——Get服务操作，以同时获取多个终端的隐私设置。UDM将返回终端的隐私设置给GMLC。GMLC将验证终端的LCS隐私配置。Step S2: GMLC sends Nudm-SDM-Get service operation to UDM to obtain the privacy settings of multiple terminals at the same time. UDM will return the privacy settings of the terminal to GMLC. GMLC will verify the LCS privacy configuration of the terminal.

如果n或n-1个终端没有被授权暴露尾椎信息，GMLC将确定停止服务且向LCS客户端或AF返回拒绝消息。在该拒绝消息中携带有失败原因。该失败原因可包括但不限于位置拒绝暴露位置信息等。If n or n-1 terminals are not authorized to expose tail vertebra information, GMLC will determine to stop the service and return a rejection message to the LCS client or AF. The rejection message carries the failure reason. The failure reason may include but is not limited to the location rejection of exposing location information.

如果小于或等于n+2个终端没有被授权暴露位置信息，GMLC将根据本地规则确定是否继续执行该流程。如果规则允许，GMLC会进入步骤3。如果规则不允许，则GMLC将停止执行该流程，且向LCS客户端或者AF发送拒绝消息。该拒绝消息包括失败原因。该失败原因可包括但不限于终端拒绝暴露位置信息等。If less than or equal to n+2 terminals are not authorized to expose location information, GMLC will determine whether to continue the process according to local rules. If the rules allow, GMLC will proceed to step 3. If the rules do not allow, GMLC will stop executing the process and send a rejection message to the LCS client or AF. The rejection message includes the reason for failure. The reason for failure may include but is not limited to the terminal refusing to expose location information.

步骤S3：GMLC向n个终端的UDM发起Nudm-UECM-Get服务操作，以选择作为测距/SL定位操作的发起终端以及该发起终端的服务AMF。Step S3: GMLC initiates the Nudm-UECM-Get service operation to the UDMs of n terminals to select the initiating terminal as the ranging/SL positioning operation and the serving AMF of the initiating terminal.

步骤S4：在漫游的场景下，(H)GMLC将向(V)GMLC发送定位且请求。Step S4: In the roaming scenario, the (H)GMLC will send a positioning request to the (V)GMLC.

步骤S5：H)GMLC和(V)GMLC向发起终端的服务AMF发起Namf-Location-ProvidePositioningInfo服务操作，以请求n-a个终端的测距结果，其中a代表因为未被授权参与测距的终端个数。该未被授权参与测距的终端是基于隐私配置的验证确定的。GMLC同时将规则发送至终端的服务AMF。Step S5: H)GMLC and (V)GMLC initiate the Namf-Location-ProvidePositioningInfo service operation to the service AMF of the initiating terminal to request the ranging results of n-a terminals, where a represents the number of terminals that are not authorized to participate in ranging. The terminals that are not authorized to participate in ranging are determined based on the verification of the privacy configuration. GMLC also sends the rules to the service AMF of the terminal.

步骤S6：如果发起终端处于CM-空闲态，AMF发起网络触发服务请求流程以建立与发起终端建立信令连接。Step S6: If the initiating terminal is in CM-idle state, AMF initiates a network triggered service request process to establish a signaling connection with the initiating terminal.

如果信令连接建立失败，Namf-Location-ProvidePositioningInfo响应将由AMF发送至GMLC。该Namf-Location-ProvidePositioningInfo响应可包括失败原因。该失败原因可为信令连接失败。(V)GMLC可向(H)GMLC发送Ngmlc-location_ProvideLocation响应。该响应可包括失败原因。基于该失败原因可是由(H)GMLC可重新选择发起终端，并重新执行步骤S3，或向LCS客户端或者AF返回拒绝消息。该拒绝消息可包括失败原因。该失败原因可包括但不限于连接失败等。If the signalling connection establishment fails, the Namf-Location-ProvidePositioningInfo response will be sent by the AMF to the GMLC. The Namf-Location-ProvidePositioningInfo response may include a failure reason. The failure reason may be a signaling connection failure. The (V)GMLC may send a Ngmlc-location_ProvideLocation response to the (H)GMLC. The response may include a failure reason. Based on the failure reason, the (H)GMLC may reselect an initiating terminal and re-execute step S3, or return a rejection message to the LCS client or AF. The rejection message may include a failure reason. The failure reason may include, but is not limited to, a connection failure.

步骤S7-S8：如果隐私配置包含第二指示或者第二指示指示需要与用户交互，则AMF通过NAS-Location_Notification Invoke Request和NAS-Location_Notification return result与终端进行信息交互，从而获取到用户指示。Steps S7-S8: If the privacy configuration includes a second indication or the second indication requires interaction with the user, the AMF interacts with the terminal through NAS-Location_Notification Invoke Request and NAS-Location_Notification return result to obtain the user indication.

在m个终端中，如果有终端的用户拒绝位置信息暴露、或有终端在指定时间内未回复，或有部分终端位于网络覆盖范围外，则服务AMF不能与终端建立NAS连接。AMF可根据规则确定是否继续该流程。Among the m terminals, if the user of a terminal refuses to expose the location information, or a terminal does not respond within the specified time, or some terminals are out of network coverage, the service AMF cannot establish a NAS connection with the terminal. The AMF can determine whether to continue the process according to the rules.

如果规则允许，则AMF执行步骤S9；If the rule allows, the AMF executes step S9;

如果规则不允许，则AMF将停止执行该流程，且向(H)GMLC返回拒绝消息。该拒绝消息可通过(V)GMLC返回给(H)GMLC。该拒绝消息可包括失败原因。该失败原因可包括：拒绝位置信息暴露、无响应、规则不允许等。该拒绝消息还可包括：拒绝位置信息暴露的终端抢单、位于网络覆盖范围外的终端清单等。可选地，该拒绝消息可包括多种失败原因。示例性地，该失败原因可包括但不限于：各个终端的失败原因。例如，终端1拒绝位置暴露，终端2的连接失败、终端3无用户响应。If the rules do not allow, the AMF will stop executing the process and return a rejection message to the (H)GMLC. The rejection message can be returned to the (H)GMLC via the (V)GMLC. The rejection message may include the reason for failure. The reason for failure may include: rejection of location information exposure, no response, rule not allowed, etc. The rejection message may also include: rejection of terminal orders for location information exposure, a list of terminals outside the network coverage, etc. Optionally, the rejection message may include multiple reasons for failure. Exemplarily, the failure reason may include, but is not limited to: the failure reason of each terminal. For example, terminal 1 rejects location exposure, terminal 2 fails to connect, and terminal 3 has no user response.

步骤S9:服务AMF选择发起测距/SL定位的发起终端，且向发起终端的LMF发送NLmf_Location_Determine_Location服务操作，以请求测距结果。该策觉结果可包括步骤5中确定的n-a-b个终端的测距结果,其中，b指示基于隐私设备不参与测距的终端个数。Step S9: The serving AMF selects the initiating terminal that initiates ranging/SL positioning, and sends the NLmf_Location_Determine_Location service operation to the LMF of the initiating terminal to request the ranging result. The ranging result may include the ranging results of the n-a-b terminals determined in step 5, where b indicates the number of terminals that do not participate in ranging based on privacy devices.

步骤S10-S19可为常规的执行测距/SL定位的步骤。Steps S10-S19 may be conventional steps for performing ranging/SL positioning.

步骤S20：当在LCF服务响应中暴露测距/SL测距结果时，GMLC将通知LCS客户端或AF实际参与测距的终端的信息。具体可包括：在响应中指示参与测距的终端和/或未参与测距的终端。Step S20: When the ranging/SL ranging result is exposed in the LCF service response, the GMLC will notify the LCS client or AF of the information of the terminals actually participating in the ranging, which may specifically include: indicating the terminals participating in the ranging and/or the terminals not participating in the ranging in the response.
