The method is executed by the SMF network element, thereby providing a method for performing positioning verification on the UE by the SMF network element. As shown in FIG. 2 , the UE positioning verification method includes the following steps:

图3示出了根据本公开实施例的一种UE定位验证方法的流程示意图。该方法由SMF网元执行，从而提供了由SMF网元对UE执行定位验证的方法，在图2所示实施例的基础上，如图3所示，该UE定位验证方法包括以下步骤：FIG. 3 shows a schematic flowchart of a method for UE positioning verification according to an embodiment of the present disclosure. The method is executed by the SMF network element, thereby providing a method for performing positioning verification on the UE by the SMF network element. On the basis of the embodiment shown in FIG. 2 , as shown in FIG. 3 , the UE positioning verification method includes the following steps:

S301，基于定位验证信息或定位验证指示，确定是否针对UE执行定位验证。S301 , based on the positioning verification information or the positioning verification indication, determine whether to perform positioning verification for the UE.

其中，定位验证信息包括卫星链路指示和UE的位置标识信息中的至少一个。卫星链路指示用于指示UE是否正在使用卫星接入和卫星回程中的至少一种。位置标识信息包括以下信息中的至少一种：UE所在小区的标识、小区所属接入网节点的标识、以及UE对应的跟踪区域标识TAI。The positioning verification information includes at least one of a satellite link indication and UE location identification information. The satellite link indication is used to indicate whether the UE is using at least one of satellite access and satellite backhaul. The location identification information includes at least one of the following information: the identification of the cell where the UE is located, the identification of the access network node to which the cell belongs, and the tracking area identification TAI corresponding to the UE.

SMF网元可以基于卫星链路指示和/或UE的位置标识信息来确定是否针对UE执行定位验证。在一些实施例中，SMF网元可以无需进行判断而直接确定针对UE执行定位验证或确定不针对UE执行定位验证。即，SMF网元可以基于卫星链路指示和/或UE的位置标识信息来确定针对UE执行定位验证，或者SMF网元可以基于卫星链路指示和/或UE的位置标识信息来确定不针对UE执行定位验证。The SMF network element may determine whether to perform positioning verification for the UE based on the satellite link indication and/or the location identification information of the UE. In some embodiments, the SMF network element may directly determine to perform positioning verification for the UE or determine not to perform positioning verification for the UE without making a judgment. That is, the SMF network element may determine to perform positioning verification for the UE based on the satellite link indication and/or the location identification information of the UE, or the SMF network element may determine not to perform positioning verification for the UE based on the satellite link indication and/or the location identification information of the UE Perform location verification.

在一些实施例中，SMF网元可以基于卫星链路指示来确定是否针对UE执行定位验证，其中卫星链路指示用于指示UE是否正在使用卫星接入和/或卫星回程。在一些实施例中，SMF网元可以基于卫星链路指示来确定针对UE执行定位验证，其中卫星链路指示用于指示UE正在使用卫星接入和/或卫星回程。在一些实施例中，SMF网元可以基于卫星链路指示来确定不针对UE执行定位验证，其中卫星链路指示用于指示UE没有正在使用卫星接入和/或卫星回程。例如，如果检测到UE正在使用卫星接入和/或卫星回程，由于卫星的覆盖范围通常很大，有可能覆盖多个服务区域，例如可以覆盖多个省、甚至国家，在这种情况下，通过UE的上报位置信息(通常为小区标识、基站标识等)识别的覆盖可能大于兴趣域，则可能需要执行UE定位验证以识别UE的更准确位置信息，SMF网元基于指示UE正在使用卫星接入和/或卫星回程的卫星链路指示确定针对UE执行定位验证。又例如，如果检测到UE没有正在使用卫星接入和/或卫星回程，则可能不需要执行UE定位验证，SMF网元基于指示UE没有正在使用卫星接入和/或卫星回程的卫星链路指示确定不针对UE执行定位验证。因此，SMF网元可以基于指示UE是否正在使用卫星接入和/或卫星回程的卫星链路指示确定是否针对UE执行定位验证。In some embodiments, the SMF network element may determine whether to perform positioning verification for the UE based on a satellite link indication used to indicate whether the UE is using satellite access and/or satellite backhaul. In some embodiments, the SMF network element may determine to perform positioning verification for the UE based on the satellite link indication, which is used to indicate that the UE is using satellite access and/or satellite backhaul. In some embodiments, the SMF network element may determine not to perform location verification for the UE based on the satellite link indication, which is used to indicate that the UE is not using satellite access and/or satellite backhaul. For example, if it is detected that the UE is using satellite access and/or satellite backhaul, since the coverage of satellites is usually large, it is possible to cover multiple service areas, such as multiple provinces or even countries, in which case, The coverage identified by the UE's reported location information (usually cell ID, base station ID, etc.) may be larger than the area of interest, and UE positioning verification may need to be performed to identify the UE's more accurate position information. The SMF network element indicates that the UE is using satellite The satellite link indication for inbound and/or satellite backhaul determines to perform positioning verification for the UE. As another example, if it is detected that the UE is not using satellite access and/or satellite backhaul, UE positioning verification may not need to be performed, the SMF network element is based on the satellite link indication indicating that the UE is not using satellite access and/or satellite backhaul It is determined that positioning verification is not performed for the UE. Accordingly, the SMF network element may determine whether to perform positioning verification for the UE based on the satellite link indication indicating whether the UE is using satellite access and/or satellite backhaul.

在另一些实施例中，SMF网元可以基于UE的位置位置标识信息来确定是否针对UE执行定位验证，其中UE的位置位置标识信息包括以下信息中的至少一种：UE所在小区的标识、小区所属接入网节点的标识、以及UE对应的跟踪区域标识(TAI，Tracking Area Identity)。在一些实施例中，SMF网元可以基于UE的位置位置标识信息来确定针对UE执行定位验证，或者SMF网元可以基于UE的位置标识信息来确定不针对UE执行定位验证。例如，如果业务需求要对进入某个区域，例如，进入商场等场所的UE推送广告信息等，而由于通过UE的上报位置信息(通常为小区标识、基站标识等)识别的覆盖通常大于该区域，在这种情况下，为了避免向未进入该区域的UE误推送广告信息，可能需要执行UE定位验证以识别UE的更准确位置信息，SMF网元可以基于UE的位置标识信息来确定针对UE执行定位验证。又例如，如果UE的位置标识信息显示UE并未进入该商场，则可能不需要执行UE定位验证，SMF网元可以基于UE的位置标识信息来确定不针对UE执行定位验证。因此，SMF网元可以基于UE的位置标识信息来确定是否针对UE执行定位验证。In other embodiments, the SMF network element may determine whether to perform positioning verification for the UE based on the location and location identification information of the UE, where the location and location identification information of the UE includes at least one of the following information: an identifier of a cell where the UE is located, a cell The identity of the access network node to which it belongs, and the tracking area identity (TAI, Tracking Area Identity) corresponding to the UE. In some embodiments, the SMF network element may determine to perform positioning verification for the UE based on the location identification information of the UE, or the SMF network element may determine not to perform positioning verification for the UE based on the location identification information of the UE. For example, if the business needs to push advertisement information to a UE entering a certain area, for example, entering a shopping mall and other places, the coverage identified by the UE's reported location information (usually cell ID, base station ID, etc.) is usually larger than the area. In this case, in order to avoid falsely pushing advertisement information to UEs that do not enter the area, it may be necessary to perform UE positioning verification to identify more accurate position information of the UE. Perform location verification. For another example, if the location identification information of the UE shows that the UE has not entered the mall, UE positioning verification may not be performed, and the SMF network element may determine not to perform positioning verification for the UE based on the location identification information of the UE. Therefore, the SMF network element may determine whether to perform location verification for the UE based on the location identification information of the UE.

在另一些实施例中，SMF网元可以基于卫星链路指示和UE的位置标识信息来确定是否针对UE执行定位验证，其中卫星链路指示用于指示UE是否正在使用卫星接入和/或卫星回程；UE的位置标识信息包括以下信息中的至少一种：UE所在小区的标识、小区所属接入网节点的标识、以及UE对应的跟踪区域标识TAI。在一些实施例中，SMF网元可以基于卫星链路指示和UE的位置标识信息来确定针对UE执行定位验证，其中卫星链路指示用于指示UE正在使用卫星接入和/或卫星回程；UE的位置标识信息包括以下信息中的至少一种：UE所在小区的标识、小区所属接入网节点的标识、以及UE对应的跟踪区域标识TAI。在一些实施例中，SMF网元可以基于卫星链路指示和UE的位置标识信息来确定不针对UE执行定位验证，其中卫星链路指示用于指示UE没有正在使用卫星接入和/或卫星回程；UE的位置标识信息包括以下信息中的至少一种：UE所在小区的标识、小区所属接入网节点的标识、以及UE对应的跟踪区域标识TAI。例如，如果检测到UE正在使用卫星接入和/或卫星回程，由于卫星的覆盖范围通常很大，有可能覆盖多个服务区域，例如可以覆盖多个省、甚至国家，而业务需求要求对跨越服务区的UE推送提示信息等，在这种情况下，由于通过UE的上报位置信息(通常为小区标识、基站标识等)难以识别UE是否跨越服务区，因此可能需要执行UE定位验证以更准确地识别UE是否跨越服务区。因此，SMF网元可以基于卫星链路指示和UE的位置标识信息来确定是否针对UE执行定位验证。In other embodiments, the SMF network element may determine whether to perform positioning verification for the UE based on the satellite link indication and the UE's location identification information, wherein the satellite link indication is used to indicate whether the UE is using satellite access and/or satellite Backhaul; the location identity information of the UE includes at least one of the following information: the identity of the cell where the UE is located, the identity of the access network node to which the cell belongs, and the tracking area identity TAI corresponding to the UE. In some embodiments, the SMF network element may determine to perform positioning verification for the UE based on the satellite link indication and the UE's location identification information, wherein the satellite link indication is used to indicate that the UE is using satellite access and/or satellite backhaul; the UE The location identification information includes at least one of the following information: the identification of the cell where the UE is located, the identification of the access network node to which the cell belongs, and the tracking area identification TAI corresponding to the UE. In some embodiments, the SMF network element may determine not to perform location verification for the UE based on the satellite link indication and the UE's location identification information, where the satellite link indication is used to indicate that the UE is not using satellite access and/or satellite backhaul ; The location identification information of the UE includes at least one of the following information: the identification of the cell where the UE is located, the identification of the access network node to which the cell belongs, and the tracking area identification TAI corresponding to the UE. For example, if it is detected that the UE is using satellite access and/or satellite backhaul, since the coverage of satellites is usually large, it is possible to cover multiple service areas, such as multiple provinces or even countries, and business needs require In this case, it is difficult to identify whether the UE crosses the service area through the reported location information of the UE (usually cell ID, base station ID, etc.), so it may be necessary to perform UE positioning verification to be more accurate. to identify whether the UE crosses the service area. Therefore, the SMF network element can determine whether to perform positioning verification for the UE based on the satellite link indication and the location identification information of the UE.

此外，SMF网元可以基于定位验证指示来确定是否针对UE执行定位验证。在本实施例中，定位验证指示可以来自其他网元。例如，该定位验证指示可以来自策略控制功能(PCF，policy control function)网元。该定位验证指示可以是其他网元基于定位验证信息得出。其中，定位验证信息可以包括卫星链路指示和UE的位置标识信息中的至少一个。卫星链路指示可以用于指示UE是否正在使用卫星接入和卫星回程中的至少一种。位置标识信息可以包括以下信息中的至少一种：UE所在小区的标识、小区所属接入网节点的标识、以及UE对应的跟踪区域标识TAI。其他网元可以基于定位验证信息确定是否针对UE执行定位验证，并在确定执行定位验证时，向SMF网元发送定位验证指示。其中，其他网元基于定位验证信息得出定位验证指示的方式可以参考以上SMF网元基于定位验证信息确定是否针对UE执行定位验证的描述。Furthermore, the SMF network element may determine whether to perform positioning verification for the UE based on the positioning verification indication. In this embodiment, the location verification indication may come from other network elements. For example, the location verification indication may come from a policy control function (PCF, policy control function) network element. The location verification indication may be obtained by other network elements based on the location verification information. The positioning verification information may include at least one of a satellite link indication and UE location identification information. The satellite link indication may be used to indicate whether the UE is using at least one of satellite access and satellite backhaul. The location identification information may include at least one of the following information: an identification of a cell where the UE is located, an identification of an access network node to which the cell belongs, and a tracking area identification TAI corresponding to the UE. Other network elements may determine whether to perform positioning verification for the UE based on the positioning verification information, and send a positioning verification indication to the SMF network element when determining to perform positioning verification. The manner in which other network elements obtain the positioning verification indication based on the positioning verification information may refer to the above description of whether the SMF network element determines whether to perform positioning verification for the UE based on the positioning verification information.

具体地，其他网元可以基于定位验证信息和在其他网元中的预配置策略得出。预配置策略可以包括以下信息中的至少一种：使用卫星链路的UE是否需要比小区级定位粒度更细的粒度的信息、需要比小区级定位粒度更细的粒度的UE业务信息、及指定需要比小区级定位粒度更细的粒度的区域的策略信息。其他网元可以基于定位验证信息和其他网元中预配置的策略确定是否针对UE执行定位验证，并在确定执行定位验证时，向SMF网元发送定位验证指示。Specifically, the other network elements can be obtained based on the location verification information and the preconfigured policies in the other network elements. The pre-configured policy may include at least one of the following information: whether the UE using the satellite link needs information with finer granularity than cell-level positioning granularity, UE traffic information requiring finer granularity than cell-level positioning granularity, and specifying Policy information for areas requiring finer granularity than cell-level positioning granularity. Other network elements may determine whether to perform positioning verification for the UE based on the positioning verification information and policies preconfigured in other network elements, and send a positioning verification instruction to the SMF network element when determining to perform positioning verification.

也就是说，SMF网元可以从其他网元接收到定位验证指示并基于定位验证指示来确定是否针对UE执行定位验证。在一些实施例中，SMF网元可以无需进行判断而直接确定针对UE执行定位验证或确定不针对UE执行定位验证。即，SMF网元可以基于定位验证指示(例如，该定位验证指示可以指示进行定位验证)来确定针对UE执行定位验证，或者SMF网元可以基于定位验证指示(例如，该定位验证指示为否定指示，即其指示不进行定位验证)来确定不针对UE执行定位验证。当然，在一些实施例中，如果没有接收到定位验证指示，则默认确定不针对UE执行定位验证。That is, the SMF network element may receive the positioning verification indication from other network elements and determine whether to perform positioning verification for the UE based on the positioning verification indication. In some embodiments, the SMF network element may directly determine to perform positioning verification for the UE or determine not to perform positioning verification for the UE without making a judgment.

UE traffic information with a granularity of 100 Å, and policy information specifying areas that require finer granularity than cell-level positioning granularity.

在本实施例中，SMF网元可以基于包括卫星链路指示和/或UE的位置标识信息的定位验证信息和预配置策略来确定是否针对UE执行定位验证。在一些实施例中，SMF网元可以无需进行判断而直接确定针对UE执行定位验证或确定不针对UE执行定位验证。即，SMF网元可以基于包括卫星链路指示和/或UE的位置标识信息的定位验证信息和预配置策略来确定针对UE执行定位验证，或者SMF网元可以基于包括卫星链路指示和/或UE的位置标识信息的定位验证信息和预配置策略来确定不针对UE执行定位验证。In this embodiment, the SMF network element may determine whether to perform positioning verification for the UE based on the positioning verification information including the satellite link indication and/or the location identification information of the UE and a pre-configured policy. In some embodiments, the SMF network element may directly determine to perform positioning verification for the UE or determine not to perform positioning verification for the UE without making a judgment. That is, the SMF network element may determine to perform positioning verification for the UE based on the positioning verification information including the satellite link indication and/or the UE's location identification information and the pre-configured policy, or the SMF network element may determine to perform positioning verification for the UE based on the positioning verification information including the satellite link indication and/or The location verification information of the UE's location identification information and a pre-configured policy determine not to perform location verification for the UE.

在一些实施例中，SMF网元可以基于卫星链路指示和预配置策略来确定是否针对UE执行定位验证，其中卫星链路指示用于指示UE是否正在使用卫星接入和/或卫星回程。在一些实施例中，SMF网元可以基于卫星链路指示和预配置策略来确定针对UE执行定位验证，其中卫星链路指示用于指示UE正在使用卫星接入和/或卫星回程。在一些实施例中，SMF网元可以基于卫星链路指示和预配置策略来确定不针对UE执行定位验证，其中卫星链路指示用于指示UE没有正在使用卫星接入和/或卫星回程。例如，如果检测到UE使用卫星接入和/或卫星回程，由于卫星的覆盖范围通常很大，有可能覆盖多个服务区域，例如可以覆盖多个省、甚至国家，在这种情况下，通过UE的上报位置信息(通常为小区标识、基站标识等)识别的覆盖可能大于兴趣域，而如果SMF网元中预配置的策略指示使用卫星接入和/或卫星链路的UE需要比小区级定位粒度更细的粒度，则需要执行UE定位验证以识别UE的更准确位置信息，SMF网元基于指示UE正在使用卫星接入和/或卫星回程的卫星链路指示和预配置策略确定针对UE执行定位验证；而如果SMF网元中预配置的策略指示使用卫星接入和/或卫星链路的UE不需要比小区级定位粒度更细的粒度，则不需要执行UE定位验证，SMF网元基于指示UE没有正在使用卫星接入和/或卫星回程的卫星链路指示和预配置策略确定针对UE执行定位验证。因此，SMF网元可以基于指示UE是否正在使用卫星接入和/或卫星回程的卫星链路指示和预配置策略来确定是否针对UE执行定位验证。In some embodiments, the SMF network element may determine whether to perform positioning verification for the UE based on a satellite link indication used to indicate whether the UE is using satellite access and/or satellite backhaul and a preconfigured policy. In some embodiments, the SMF network element may determine to perform positioning verification for the UE based on a satellite link indication used to indicate that the UE is using satellite access and/or satellite backhaul, and a preconfigured policy. In some embodiments, the SMF network element may determine not to perform location verification for the UE based on a satellite link indication used to indicate that the UE is not using satellite access and/or satellite backhaul, and a preconfigured policy. For example, if it is detected that the UE uses satellite access and/or satellite backhaul, since the coverage of satellites is usually large, it is possible to cover multiple service areas, such as multiple provinces or even countries, in this case, through The coverage identified by the UE's reported location information (usually cell ID, base station ID, etc.) may be larger than the area of interest, and if the pre-configured policy in the SMF network element indicates that the UE using satellite access and/or satellite link needs to be more than cell-level The positioning granularity is finer, and UE positioning verification needs to be performed to identify more accurate position information of the UE. The SMF network element determines the target for the UE based on the satellite link indication indicating that the UE is using satellite access and/or satellite backhaul and a pre-configured policy. Perform positioning verification; whereas if the pre-configured policy in the SMF network element indicates that UEs using satellite access and/or satellite links do not need a finer granularity than cell-level positioning granularity, then the UE positioning verification does not need to be performed, the SMF network element The determination to perform location verification for the UE is based on a satellite link indication and a preconfigured policy indicating that the UE is not using satellite access and/or satellite backhaul. Accordingly, the SMF network element may determine whether to perform location verification for the UE based on a satellite link indication and a preconfigured policy indicating whether the UE is using satellite access and/or satellite backhaul.

在另一些实施例中，SMF网元可以基于UE的位置标识信息和预配置策略来确定是否针对UE执行定位验证，其中UE的位置标识信息包括以下信息中的至少一种：UE所在小区的标识、小区所属接入网节点的标识、以及UE对应的跟踪区域标识TAI。在一些实施例中，SMF网元可以基于UE的位置标识信息和预配置策略来确定针对UE执行定位验证，或者SMF网元可以基于UE的位置标识信息和预配置策略来确定不针对UE执行定位验证。例如，SMF网元中预配置的策略指示需要比小区级定位粒度更细的粒度的UE订阅业务，如果UE已经订阅了上述UE订阅业务中的某项业务，例如，该业务为要对进入某个区域，例如，进入商场等场所的UE推送广告信息等，而由于通过UE的上报位置信息(通常为小区标识、基站标识等)识别的覆盖通常大于该区域，在这种情况下，为了避免向未进入该区域的UE误推送广告信息，需要执行UE定位验证以识别UE的更准确位置信息，SMF网元可以基于UE的位置标识信息和预配置策略来确定针对UE执行定位验证。又例如，如果UE的位置标识信息显示UE并未进入该商场，则可能不需要执行UE定位验证，SMF网元可以基于UE的位置标识信息和预配置策略来确定不针对UE执行定位验证。因此，SMF网元可以基于UE的位置标识信息和预配置策略来确定是否针对UE执行定位验证。In other embodiments, the SMF network element may determine whether to perform positioning verification for the UE based on the location identification information of the UE and a pre-configured policy, where the location identification information of the UE includes at least one of the following information: an identification of a cell where the UE is located. , the identifier of the access network node to which the cell belongs, and the tracking area identifier TAI corresponding to the UE. In some embodiments, the SMF network element may determine to perform positioning verification for the UE based on the location identification information of the UE and a preconfigured policy, or the SMF network element may determine not to perform positioning for the UE based on the location identification information of the UE and the preconfigured policy verify. For example, the pre-configured policy in the SMF network element indicates that UE subscription services with finer granularity than cell-level positioning granularity are required. If the UE has subscribed to a certain service in the above UE subscription services, for example, the service For example, UEs entering shopping malls and other places push advertisement information, etc., and because the coverage identified by the UE's reported location information (usually cell ID, base station ID, etc.) is usually larger than the area, in this case, in order to avoid To push advertisement information to UEs that do not enter the area by mistake, UE positioning verification needs to be performed to identify more accurate location information of the UE. The SMF network element can determine to perform positioning verification for the UE based on the UE's location identification information and pre-configured policies. For another example, if the location identification information of the UE shows that the UE has not entered the mall, UE positioning verification may not be performed, and the SMF network element may determine not to perform positioning verification for the UE based on the location identification information of the UE and a preconfigured policy. Therefore, the SMF network element may determine whether to perform positioning verification for the UE based on the UE's location identification information and a preconfigured policy.

在另一些实施例中，SMF网元可以基于卫星链路指示、UE的位置标识信息和预配置策略来确定是否针对UE执行定位验证，其中卫星链路指示用于指示UE是否正在使用卫星接入和/或卫星回程；UE的位置标识信息包括以下信息中的至少一种：UE所在小区的标识、小区所属接入网节点的标识、以及UE对应的跟踪区域标识TAI。在一些实施例中，SMF网元可以基于卫星链路指示、UE的位置标识信息和预配置策略来确定针对UE执行定位验证，其中卫星链路指示用于指示UE正在使用卫星接入和/或卫星回程；UE的位置标识信息包括以下信息中的至少一种：UE所在小区的标识、小区所属接入网节点的标识、以及UE对应的跟踪区域标识TAI。在一些实施例中，SMF网元可以基于卫星链路指示、UE的位置标识信息和预配置策略来确定不针对UE执行定位验证，其中卫星链路指示用于指示UE没有正在使用卫星接入和/或卫星回程；UE的位置标识信息包括以下信息中的至少一种：UE所在小区的标识、小区所属接入网节点的标识、以及UE对应的跟踪区域标识TAI。例如，如果检测到UE正在使用卫星接入和/或卫星回程，由于卫星的覆盖范围通常很大，有可能覆盖多个服务区域，例如可以覆盖多个省、甚至国家，而UE已经订阅了某项业务为SMF网元中预配置的策略指示的需要比小区级定位粒度更细的粒度的UE订阅业务，例如订阅业务对跨越服务区的UE采用不同费率等，在这种情况下，由于通过UE的上报位置信息(通常为小区标识、基站标识等)难以识别UE是否跨越服务区，因此需要执行UE定位验证以更准确地识别UE是否跨越服务区。因此，SMF网元可以基于卫星链路指示、UE的位置标识信息和预配置策略来确定是否针对UE执行定位验证。In other embodiments, the SMF network element may determine whether to perform location verification for the UE based on the satellite link indication, the UE's location identification information, and a pre-configured policy, wherein the satellite link indication is used to indicate whether the UE is using satellite access and/or satellite backhaul; the location identity information of the UE includes at least one of the following information: the identity of the cell where the UE is located, the identity of the access network node to which the cell belongs, and the tracking area identity TAI corresponding to the UE. In some embodiments, the SMF network element may determine to perform location verification for the UE based on a satellite link indication, which is used to indicate that the UE is using satellite access and/or a pre-configured policy, and the UE's location identification information Satellite backhaul; the location identification information of the UE includes at least one of the following information: the identification of the cell where the UE is located, the identification of the access network node to which the cell belongs, and the tracking area identification TAI corresponding to the UE. In some embodiments, the SMF network element may determine not to perform positioning verification for the UE based on the satellite link indication, which is used to indicate that the UE is not using satellite access and /or satellite backhaul; the location identity information of the UE includes at least one of the following information: the identity of the cell where the UE is located, the identity of the access network node to which the cell belongs, and the tracking area identity TAI corresponding to the UE. For example, if it is detected that the UE is using satellite access and/or satellite backhaul, since the coverage of satellites is usually large, it is possible to cover multiple service areas, such as multiple provinces or even countries, and the UE has subscribed to a certain service area. The service is a UE subscription service indicated by the pre-configured policy in the SMF network element that requires a finer granularity than the cell-level positioning granularity. For example, the subscription service uses different rates for UEs that cross service areas. It is difficult to identify whether the UE crosses the service area through the reported location information of the UE (usually cell identifier, base station identifier, etc.), so it is necessary to perform UE positioning verification to more accurately identify whether the UE crosses the service area. Therefore, the SMF network element can determine whether to perform positioning verification for the UE based on the satellite link indication, the UE's location identification information and the pre-configured policy.

S4012，将定位验证信息上报给策略控制功能PCF网元，以便PCF网元基于定位验证信息和PCF网元中的预配置策略确定是否针对UE执行定位验证；以及在从PCF网元接收到定位验证指示信息时，确定针对UE执行定位验证。S4012, reporting the positioning verification information to the policy control function PCF network element, so that the PCF network element determines whether to perform positioning verification for the UE based on the positioning verification information and the preconfigured policy in the PCF network element; and after receiving the positioning verification from the PCF network element When the information is indicated, it is determined to perform positioning verification for the UE.

其中预配置策略包括以下信息中的至少一种：使用卫星链路的UE是否需要比小区级定位粒度更细的粒度的信息、需要比小区级定位粒度更细的粒度的UE业务信息、及指定需要比小区级定位粒度更细的粒度的区域的策略信息，定位验证指示信息包括指示执行定位验证的定位验证指示且为PCF网元在确定针对UE执行定位验证时发送。The pre-configured policy includes at least one of the following information: whether the UE using the satellite link needs information with finer granularity than cell-level positioning granularity, UE service information requiring finer granularity than cell-level positioning granularity, and a specified Policy information for an area requiring finer granularity than cell-level positioning granularity, the positioning verification indication information includes a positioning verification indication instructing to perform positioning verification and is sent by the PCF network element when determining to perform positioning verification for the UE.

在本实施例中，SMF网元可以将定位验证信息上报给策略控制功能(PCF，policy control function)网元，而PCF网元中预配置有策略，该策略可以包括以下信息中的至少一种：使用卫星链路的UE是否需要比小区级定位粒度更细的粒度的信息、需要比小区级定位粒度更细的粒度的UE业务信息、及指定需要比小区级定位粒度更细的粒度的区域的策略信息，PCF网元可以基于包括卫星链路指示和/或UE的位置标识信息的定位验证信息和预配置策略来确定是否针对UE执行定位验证。其中，PCF网元基于定位验证信息和预配置策略来确定是否针对UE执行定位验证的方式与SMF网元基于定位验证信息和预配置策略来确定是否针对UE执行定位验证的方式类似，可参考以上描述，在此不再赘诉。如果PCF网元确定针对UE执行定位验证，则PCF网元可以向SMF网元发送定位验证指示用以指示SMF网元执行定位验证。In this embodiment, the SMF network element may report the location verification information to the policy control function (PCF, policy control function) network element, and the PCF network element is preconfigured with a policy, and the policy may include at least one of the following information : Whether the UE using the satellite link needs information with finer granularity than cell-level positioning granularity, UE service information with finer granularity than cell-level positioning granularity, and specifies areas that require finer-grained granularity than cell-level positioning granularity The PCF network element may determine whether to perform positioning verification for the UE based on the positioning verification information including the satellite link indication and/or the UE's location identification information and the preconfigured policy. The way in which the PCF network element determines whether to perform positioning verification for the UE based on the positioning verification information and the pre-configured policy is similar to the way that the SMF network element determines whether to perform the positioning verification for the UE based on the positioning verification information and the pre-configured policy. The description will not be repeated here. If the PCF network element determines to perform positioning verification for the UE, the PCF network element may send a positioning verification indication to the SMF network element to instruct the SMF network element to perform positioning verification.

在一些实施例中，定位验证指示信息包括对UE执行定位验证的时间周期。In some embodiments, the positioning verification indication information includes a time period for performing positioning verification on the UE.

在本实施例中，PCF网元可以确定按照一定的时间周期来对UE执行定位验证。PCF网元可以将对UE执行定位验证的时间周期以及定位验证指示发送给SMF网元，以指示SMF网元按照该时间周期来对UE执行定位验证。通过这种方式，可以避免总是对该UE执行定位验证，从而节省资源。In this embodiment, the PCF network element may determine to perform positioning verification on the UE according to a certain time period. The PCF network element may send a time period for performing positioning verification to the UE and a positioning verification instruction to the SMF network element, so as to instruct the SMF network element to perform positioning verification for the UE according to the time period. In this way, it is possible to avoid always performing positioning verification for the UE, thereby saving resources.

As another example, if it is detected that the UE is not using satellite access and/or satellite backhaul, then UE positioning verification may not need to be performed, the AMF network element based on the satellite link indication indicating that the UE is not using satellite access and/or satellite backhaul It is determined that positioning verification is not performed for the UE. . Accordingly, the AMF network element may determine whether to perform positioning verification for the UE based on the satellite link indication indicating whether the UE is using satellite access and/or satellite backhaul.

在另一些实施例中，AMF网元可以基于UE的位置标识信息来确定是否针对UE执行定位验证，其中UE的位置标识信息包括以下信息中的至少一种：UE所在小区的标识、小区所属接入网节点的标识、以及UE对应的跟踪区域标识TAI。在一些实施例中，AMF网元可以基于UE的位置标识信息来确定针对UE执行定位验证，或者AMF网元可以基于UE的位置标识信息来确定不针对UE执行定位验证。例如，如果业务需求要对进入某个区域，例如，进入商场等场所的UE推送广告信息等，而由于通过UE的上报位置信息(通常为小区标识、基站标识等)识别的覆盖通常大于该区域，在这种情况下，为了避免向未进入该区域的UE误推送广告信息，可能需要执行UE定位验证以识别UE的更准确位置信息，AMF网元可以基于UE的位置标识信息来确定针对UE执行定位验证。又例如，如果UE的位置标识信息显示UE并未进入该商场，则可能不需要执行UE定位验证，AMF网元可以基于UE的位置标识信息来确定不针对UE执行定位验证。因此，AMF网元可以基于UE的位置标识信息来确定是否针对UE执行定位验证。In other embodiments, the AMF network element may determine whether to perform positioning verification for the UE based on the location identification information of the UE, where the location identification information of the UE includes at least one of the following information: the identity of the cell where the UE is located, the access point to which the cell belongs, and the location identification information of the UE. The identifier of the network access node and the tracking area identifier TAI corresponding to the UE. In some embodiments, the AMF network element may determine to perform positioning verification for the UE based on the location identification information of the UE, or the AMF network element may determine not to perform positioning verification for the UE based on the location identification information of the UE. For example, if the business needs to push advertisement information to a UE entering a certain area, for example, entering a shopping mall and other places, the coverage identified by the UE's reported location information (usually cell ID, base station ID, etc.) is usually larger than the area. In this case, in order to avoid falsely pushing advertisement information to UEs that do not enter the area, it may be necessary to perform UE location verification to identify more accurate location information of the UE. Perform location verification. For another example, if the location identification information of the UE shows that the UE has not entered the mall, UE positioning verification may not be performed, and the AMF network element may determine not to perform positioning verification for the UE based on the location identification information of the UE. Therefore, the AMF network element may determine whether to perform location verification for the UE based on the location identification information of the UE.

在另一些实施例中，AMF网元可以基于卫星链路指示和UE的位置标识信息来确定是否针对UE执行定位验证，其中卫星链路指示用于指示UE是否正在使用卫星接入和/或卫星回程；UE的位置标识信息包括以下信息中的至少一种：UE所在小区的标识、小区所属接入网节点的标识、以及UE对应的跟踪区域标识TAI。在一些实施例中，AMF网元可以基于卫星链路指示和UE的位置标识信息来确定针对UE执行定位验证，其中卫星链路指示用于指示UE正在使用卫星接入和/或卫星回程；UE的位置标识信息包括以下信息中的至少一种：UE所在小区的标识、小区所属接入网节点的标识、以及UE对应的跟踪区域标识TAI。在一些实施例中，AMF网元可以基于卫星链路指示和UE的位置标识信息来确定不针对UE执行定位验证，其中卫星链路指示用于指示UE没有正在使用卫星接入和/或卫星回程；UE的位置标识信息包括以下信息中的至少一种：UE所在小区的标识、小区所属接入网节点的标识、以及UE对应的跟踪区域标识TAI。例如，如果检测到UE正在使用卫星接入和/或卫星回程，由于卫星的覆盖范围通常很大，有可能覆盖多个服务区域，例如可以覆盖多个省、甚至国家，而业务需求要求对跨越服务区的UE推送提示信息等，在这种情况下，由于通过UE的上报位置信息(通常为小区标识、基站标识等)难以识别UE是否跨越服务区，因此可能需要执行UE定位验证以更准确地识别UE是否跨越服务区。又例如，如果检测到UE正在使用卫星接入和/或卫星回程，由于卫星的覆盖范围通常很大，有可能覆盖多个服务区域，例如可以覆盖多个省、甚至国家，而如果UE跨越边境，由于不同国家有可能采用不同运营商，在这种情况下，由于通过UE的上报位置信息(通常为小区标识、基站标识等)难以识别UE是否跨越边境，因此需要执行UE定位验证以更准确地识别UE是否跨越边境，以便能够重选局域移动管理锚点(PLMA，previously attached local mobility anchor)网元。因此，AMF网元可以基于卫星链路指示和UE的位置标识信息来确定是否针对UE执行定位验证。In other embodiments, the AMF network element may determine whether to perform positioning verification for the UE based on the satellite link indication and the UE's location identification information, wherein the satellite link indication is used to indicate whether the UE is using satellite access and/or satellite Backhaul; the location identity information of the UE includes at least one of the following information: the identity of the cell where the UE is located, the identity of the access network node to which the cell belongs, and the tracking area identity TAI corresponding to the UE. In some embodiments, the AMF network element may determine to perform positioning verification for the UE based on the satellite link indication and the UE's location identification information, wherein the satellite link indication is used to indicate that the UE is using satellite access and/or satellite backhaul; the UE The location identification information includes at least one of the following information: the identification of the cell where the UE is located, the identification of the access network node to which the cell belongs, and the tracking area identification TAI corresponding to the UE. In some embodiments, the AMF network element may determine not to perform location verification for the UE based on the satellite link indication and the UE's location identification information, where the satellite link indication is used to indicate that the UE is not using satellite access and/or satellite backhaul ; The location identification information of the UE includes at least one of the following information: the identification of the cell where the UE is located, the identification of the access network node to which the cell belongs, and the tracking area identification TAI corresponding to the UE. For example, if it is detected that the UE is using satellite access and/or satellite backhaul, since the coverage of satellites is usually large, it is possible to cover multiple service areas, such as multiple provinces or even countries, and business needs require In this case, it is difficult to identify whether the UE crosses the service area through the reported location information of the UE (usually cell ID, base station ID, etc.), so it may be necessary to perform UE positioning verification to be more accurate. to identify whether the UE crosses the service area. As another example, if it is detected that the UE is using satellite access and/or satellite backhaul, since the coverage of satellites is usually large, it is possible to cover multiple service areas, such as multiple provinces or even countries, while if the UE crosses a border , since different countries may use different operators, in this case, it is difficult to identify whether the UE crosses the border through the reported location information of the UE (usually cell ID, base station ID, etc.), so it is necessary to perform UE positioning verification to be more accurate. It can identify whether the UE crosses the border, so as to be able to re-select the local mobility management anchor (PLMA, previously attached local mobility anchor) network element. Therefore, the AMF network element can determine whether to perform positioning verification for the UE based on the satellite link indication and the location identification information of the UE.

此外，AMF网元可以基于定位验证指示来确定是否针对UE执行定位验证。在本实施例中，定位验证指示可以来自其他网元。例如，该定位验证指示可以来自PCF网元或者来自SMF网元。该定位验证指示可以是其他网元基于定位验证信息得出。其中，定位验证信息可以包括卫星链路指示和UE的位置标识信息中的至少一个。卫星链路指示可以用于指示UE是否正在使用卫星接入和卫星回程中的至少一种。位置标识信息可以包括以下信息中的至少一种：UE所在小区的标识、小区所属接入网节点的标识、以及UE对应的跟踪区域标识TAI。其他网元可以基于定位验证信息确定是否针对UE执行定位验证，并在确定执行定位验证时，向AMF网元发送定位验证指示。其中，其他网元基于定位验证信息得出定位验证指示的方式可以参考以上AMF网元基于定位验证信息确定是否针对UE执行定位验证的描述。Furthermore, the AMF network element may determine whether to perform positioning verification for the UE based on the positioning verification indication. In this embodiment, the location verification indication may come from other network elements. For example, the location verification indication may come from a PCF network element or from an SMF network element. The location verification indication may be obtained by other network elements based on the location verification information. The positioning verification information may include at least one of a satellite link indication and UE location identification information. The satellite link indication may be used to indicate whether the UE is using at least one of satellite access and satellite backhaul. The location identification information may include at least one of the following information: an identification of a cell where the UE is located, an identification of an access network node to which the cell belongs, and a tracking area identification TAI corresponding to the UE. Other network elements may determine whether to perform positioning verification for the UE based on the positioning verification information, and send a positioning verification indication to the AMF network element when determining to perform positioning verification. The manner in which other network elements obtain the positioning verification indication based on the positioning verification information may refer to the above description of whether the AMF network element determines whether to perform positioning verification for the UE based on the positioning verification information.

具体地，其他网元可以基于定位验证信息和在其他网元中的预配置策略得出。预配置策略可以包括以下信息中的至少一种：使用卫星链路的UE是否需要比小区级定位粒度更细的粒度的信息、需要比小区级定位粒度更细的粒度的UE业务信息、及指定需要比小区级定位粒度更细的粒度的区域的策略信息。其他网元可以基于定位验证信息和其他网元中预配置的策略确定是否针对UE执行定位验证，并在确定执行定位验证时，向AMF网元发送定位验证指示。Specifically, the other network elements can be obtained based on the location verification information and the preconfigured policies in the other network elements. The pre-configured policy may include at least one of the following information: whether the UE using the satellite link needs information with finer granularity than cell-level positioning granularity, UE traffic information requiring finer granularity than cell-level positioning granularity, and specifying Policy information for areas requiring finer granularity than cell-level positioning granularity. Other network elements may determine whether to perform positioning verification for the UE based on the positioning verification information and policies preconfigured in other network elements, and send a positioning verification indication to the AMF network element when determining to perform positioning verification.

也就是说，AMF网元可以从其他网元接收到定位验证指示并基于定位验证指示来确定是否针对UE执行定位验证。在一些实施例中，AMF网元可以无需进行判断而直接确定针对UE执行定位验证或确定不针对UE执行定位验证。即，AMF网元可以基于定位验证指示(例如，该定位验证指示可以指示进行定位验证)来确定针对UE执行定位验证，或者AMF网元可以基于定位验证指示(例如，该定位验证指示为否定指示，即其指示不进行定位验证)来确定不针对UE执行定位验证。当然，在一些实施例中，如果没有接收到定位验证指示，则默认确定不针对UE执行定位验证。That is, the AMF network element may receive the positioning verification indication from other network elements and determine whether to perform positioning verification for the UE based on the positioning verification indication. In some embodiments, the AMF network element may directly determine to perform positioning verification for the UE or determine not to perform positioning verification for the UE without making a judgment. That is, the AMF network element may determine to perform positioning verification for the UE based on the positioning verification indication (eg, the positioning verification indication may indicate to perform positioning verification), or the AMF network element may determine to perform positioning verification for the UE based on the positioning verification indication (eg, the positioning verification indication is a negative indication) , that is, it indicates that positioning verification is not to be performed) to determine that positioning verification is not performed for the UE. Of course, in some embodiments, if no positioning verification indication is received, it is determined by default that positioning verification is not performed for the UE.

在本实施例中，AMF网元可以基于包括卫星链路指示和/或UE的位置标识信息的定位验证信息和预配置策略来确定是否针对UE执行定位验证。在一些实施例中，AMF网元可以无需进行判断而直接确定针对UE执行定位验证或确定不针对UE执行定位验证。即，AMF网元可以基于包括卫星链路指示和/或UE的位置标识信息的定位验证信息和预配置策略来确定针对UE执行定位验证，或者AMF网元可以基于包括卫星链路指示和/或UE的位置标识信息的定位验证信息和预配置策略来确定不针对UE执行定位验证。In this embodiment, the AMF network element may determine whether to perform positioning verification for the UE based on the positioning verification information including the satellite link indication and/or the location identification information of the UE and a preconfigured policy. In some embodiments, the AMF network element may directly determine to perform positioning verification for the UE or determine not to perform positioning verification for the UE without making a judgment. That is, the AMF network element may determine to perform positioning verification for the UE based on the positioning verification information including the satellite link indication and/or the UE's location identification information and the preconfigured policy, or the AMF network element may determine to perform positioning verification for the UE based on the positioning verification information including the satellite link indication and/or The location verification information of the UE's location identification information and a pre-configured policy determine not to perform location verification for the UE.

In some embodiments, the AMF network element may determine to perform location verification for the UE based on a satellite link indication used to indicate that the UE is using satellite access and/or satellite backhaul, and a preconfigured policy. In some embodiments, the AMF network element may determine not to perform location verification for the UE based on a satellite link indication used to indicate that the UE is not using satellite access and/or satellite backhaul, and a preconfigured policy. For example, if it is detected that the UE uses satellite access and/or satellite backhaul, since the coverage of satellites is usually large, it is possible to cover multiple service areas, such as multiple provinces or even countries, in this case, through The coverage identified by the reported location information of the UE (usually cell ID, base station ID, etc.) may be larger than the area of interest, and if the pre-configured policy in the AMF network element indicates that the UE using satellite access and/or satellite link needs to be more than cell-level The positioning granularity is finer, and UE positioning verification needs to be performed to identify more accurate position information of the UE. The AMF network element determines the target for the UE based on the satellite link indication indicating that the UE is using satellite access and/or satellite backhaul and a pre-configured policy. Perform positioning verification; whereas if the pre-configured policy in the AMF network element indicates that UEs using satellite access and/or satellite links do not require a finer granularity than cell-level positioning granularity, then the UE positioning verification does not need to be performed, and the AMF network element The determination to perform location verification for the UE is based on a satellite link indication and a preconfigured policy indicating that the UE is not using satellite access and/or satellite backhaul. Accordingly, the AMF network element may determine whether to perform location verification for the UE based on a satellite link indication and a preconfigured policy indicating whether the UE is using satellite access and/or satellite backhaul.

在另一些实施例中，AMF网元可以基于UE的位置标识信息和预配置策略来确定是否针对UE执行定位验证，其中UE的位置标识信息包括以下信息中的至少一种：UE所在小区的标识、小区所属接入网节点的标识、以及UE对应的跟踪区域标识TAI。在一些实施例中，AMF网元可以基于UE的位置标识信息和预配置策略来确定针对UE执行定位验证，或者AMF网元可以基于UE的位置标识信息和预配置策略来确定不针对UE执行定位验证。例如，AMF网元中预配置的策略指示需要比小区级定位粒度更细的粒度的UE订阅业务，如果UE已经订阅了上述UE订阅业务中的某项业务，例如，该业务为要对进入某个区域，例如，进入商场等场所的UE推送广告信息等，而由于通过UE的上报位置信息 (通常为小区标识、基站标识等)识别的覆盖通常大于该区域，在这种情况下，为了避免向未进入该区域的UE误推送广告信息，需要执行UE定位验证以识别UE的更准确位置信息，AMF网元可以基于UE的位置标识信息和预配置策略来确定针对UE执行定位验证。又例如，AMF网元中预配置的策略指示需要比小区级定位粒度更细的粒度的区域，如果UE进入该区域，由于通过UE的上报位置信息(通常为小区标识、基站标识等)识别的覆盖粒度不满足该区域所需粒度，在这种情况下，需要执行UE定位验证以识别UE的更准确位置信息，AMF网元可以基于UE的位置标识信息和预配置策略来确定针对UE执行定位验证。又例如，如果UE的位置标识信息显示UE并未进入该区域，则可能不需要执行UE定位验证，AMF网元可以基于UE的位置标识信息和预配置策略来确定不针对UE执行定位验证。因此，AMF网元可以基于UE的位置标识信息和预配置策略来确定是否针对UE执行定位验证。In other embodiments, the AMF network element may determine whether to perform location verification for the UE based on the location identification information of the UE and a preconfigured policy, where the location identification information of the UE includes at least one of the following information: an identifier of a cell where the UE is located. , the identifier of the access network node to which the cell belongs, and the tracking area identifier TAI corresponding to the UE. In some embodiments, the AMF network element may determine to perform positioning verification for the UE based on the UE's location identification information and a pre-configured policy, or the AMF network element may determine not to perform positioning for the UE based on the UE's location identification information and a pre-configured policy verify. For example, the pre-configured policy in the AMF network element indicates that UE subscription services with finer granularity than cell-level positioning granularity are required. If the UE has subscribed to a certain service in the above UE subscription services, for example, the service For example, UEs entering shopping malls and other places push advertisement information, etc., and because the coverage identified by the UE's reported location information (usually cell ID, base station ID, etc.) is usually larger than the area, in this case, in order to avoid To push advertisement information to UEs that do not enter the area by mistake, UE positioning verification needs to be performed to identify more accurate location information of the UE. For another example, the pre-configured policy indication in the AMF network element requires an area with finer granularity than the cell-level positioning granularity. If the UE enters the area, the location information (usually the cell ID, base station ID, etc.) identified by the UE is identified by the reported location information. The coverage granularity does not meet the granularity required for the area. In this case, UE positioning verification needs to be performed to identify the more accurate position information of the UE. The AMF network element can determine to perform positioning for the UE based on the UE's position identification information and pre-configured policies. verify. For another example, if the location identification information of the UE shows that the UE does not enter the area, UE positioning verification may not be performed, and the AMF network element may determine not to perform positioning verification for the UE based on the location identification information of the UE and a preconfigured policy. Therefore, the AMF network element can determine whether to perform positioning verification for the UE based on the UE's location identification information and a preconfigured policy.

在另一些实施例中，AMF网元可以基于卫星链路指示、UE的位置标识信息和预配置策略来确定是否针对UE执行定位验证，其中卫星链路指示用于指示UE是否正在使用卫星接入和/或卫星回程；UE的位置标识信息包括以下信息中的至少一种：UE所在小区的标识、小区所属接入网节点的标识、以及UE对应的跟踪区域标识TAI。在一些实施例中，AMF网元可以基于卫星链路指示、UE的位置标识信息和预配置策略来确定针对UE执行定位验证，其中卫星链路指示用于指示UE正在使用卫星接入和/或卫星回程；UE的位置标识信息包括以下信息中的至少一种：UE所在小区的标识、小区所属接入网节点的标识、以及UE对应的跟踪区域标识TAI。在一些实施例中，AMF网元可以基于卫星链路指示、UE的位置标识信息和预配置策略来确定不针对UE执行定位验证，其中卫星链路指示用于指示UE没有正在使用卫星接入和/或卫星回程；UE的位置标识信息包括以下信息中的至少一种：UE所在小区的标识、小区所属接入网节点的标识、以及UE对应的跟踪区域标识TAI。例如，如果检测到UE正在使用卫星接入和/或卫星回程，由于卫星的覆盖范围通常很大，有可能覆盖多个服务区域，例如可以覆盖多个省、甚至国家，而UE已经订阅了某项业务为AMF网元中预配置的策略指示的需要比小区级定位粒度更细的粒度的UE订阅业务，例如订阅业务要求对跨越服务区的UE采用不同费率等，在这种情况下，由于通过UE的上报位置信息(通常为小区标识、基站标识等)难以识别UE是否跨越服务区，因此需要执行UE定位验证以更准确地识别UE是否跨越服务区。又例如，如果检测到UE正在使用卫星接入和/或卫星回程，由于卫星的覆盖范围通常很大，有可能覆盖多个服务区域，例如可以覆盖多个省、甚至国家，而如果UE跨越边境，由于不同国家有可能采用不同运营商，在这种情况下，由于通过UE的上报位置信息(通常为小区标识、基站标识等)难以识别UE是否跨越边境，因此需要执行UE定位验证以更准确地识别UE是否跨越边境，以便能够重选局域移动管理锚点(PLMA，previously attached local mobility anchor)网元。因此，AMF网元可以基于卫星链路指示、UE的位置标识信息和预配置策略来确定是否针对UE执行定位验证。In other embodiments, the AMF network element may determine whether to perform positioning verification for the UE based on the satellite link indication, the UE's location identification information, and a pre-configured policy, wherein the satellite link indication is used to indicate whether the UE is using satellite access and/or satellite backhaul; the location identity information of the UE includes at least one of the following information: the identity of the cell where the UE is located, the identity of the access network node to which the cell belongs, and the tracking area identity TAI corresponding to the UE. In some embodiments, the AMF network element may determine to perform location verification for the UE based on a satellite link indication, which is used to indicate that the UE is using satellite access and/or Satellite backhaul; the location identification information of the UE includes at least one of the following information: the identification of the cell where the UE is located, the identification of the access network node to which the cell belongs, and the tracking area identification TAI corresponding to the UE. In some embodiments, the AMF network element may determine not to perform positioning verification for the UE based on the satellite link indication, which is used to indicate that the UE is not using satellite access and /or satellite backhaul; the location identity information of the UE includes at least one of the following information: the identity of the cell where the UE is located, the identity of the access network node to which the cell belongs, and the tracking area identity TAI corresponding to the UE. For example, if it is detected that the UE is using satellite access and/or satellite backhaul, since the coverage of satellites is usually large, it is possible to cover multiple service areas, such as multiple provinces or even countries, and the UE has subscribed to a certain service area. The service is a UE subscription service that requires a finer granularity than the cell-level positioning granularity indicated by the preconfigured policy in the AMF network element. For example, the subscription service requires different rates for UEs that cross service areas. In this case, Since it is difficult to identify whether the UE crosses the service area through the reported location information of the UE (usually the cell identifier, base station identifier, etc.), it is necessary to perform UE positioning verification to more accurately identify whether the UE crosses the service area. For another example, if it is detected that the UE is using satellite access and/or satellite backhaul, since the coverage of satellites is usually large, it is possible to cover multiple service areas, such as multiple provinces or even countries, while if the UE crosses a border , since different countries may use different operators, in this case, it is difficult to identify whether the UE crosses the border through the reported location information of the UE (usually cell ID, base station ID, etc.), so it is necessary to perform UE positioning verification to be more accurate. It can identify whether the UE crosses the border, so as to be able to re-select the local mobility management anchor (PLMA, previously attached local mobility anchor) network element. Therefore, the AMF network element can determine whether to perform positioning verification for the UE based on the satellite link indication, the UE's location identification information and the pre-configured policy.
