In the current mobile communication network system, the location information of user equipment (UE, user equipment) can be reported to the network side. However, in some scenarios, the accuracy of the location information reported by the user equipment may not meet the requirements, and the reported location information needs to be verified to obtain more accurate location information. However, in the prior art, there is no method of how to determine whether positioning verification is required.

Therefore, the present application provides a confirmation method and device for UE positioning verification, which can determine whether to perform positioning verification for the UE based on positioning verification information, thereby making up for the lack of how to determine whether to perform UE positioning verification in the prior art.

FIG. 1 shows a schematic flowchart of a method for confirming UE positioning verification according to an embodiment of the present disclosure. The method is executed by the first network element, thereby providing a confirmation method for performing positioning verification on the UE. As shown in FIG. 1 , the confirmation method for the UE positioning verification includes the following steps:

S101, based on the positioning verification information, determine whether to perform positioning verification for the UE.

In the embodiments of the present disclosure, the network device can determine whether to perform positioning verification for the UE based on the positioning verification information, thereby making up for the lack of how to determine whether to perform the UE positioning verification in the prior art.

In some embodiments, the location verification information may include at least one of a satellite link indication and location identification information of the UE. 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.

That is, the first 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 first 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 first 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 first network element may determine not to perform the positioning verification based on the satellite link indication and/or the location identification information of the UE. Perform positioning verification for the UE.

In some embodiments, the first network element may determine not to perform location verification for the UE based on a satellite link indication, wherein the satellite link indication 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 first network element is based on indicating that the UE is using satellites The satellite link indication for access and/or satellite backhaul determines that positioning verification is performed for the UE. As another example, if it is detected that the UE is not using satellite access and/or satellite backhaul, it may not be necessary to perform UE positioning verification, the first network element is based on a satellite link indicating that the UE is not using satellite access and/or satellite backhaul Indicates that it is determined not to perform positioning verification for the UE. Accordingly, the first 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.

In some other embodiments, the first network element may determine whether to perform positioning verification for the UE based on location identification information of the UE, 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, a The identity of the access network node and the tracking area identity (TAI, Tracking Area Identity) corresponding to the UE. In some embodiments, the first network element may determine to perform positioning verification for the UE based on the location identification information of the UE, or the first 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. The UE performs positioning verification. For another example, if the location identification information of the UE shows that the UE has not entered the mall, the UE positioning verification may not need to be performed, and the first network element may determine not to perform positioning verification for the UE based on the location identification information of the UE. Therefore, the first network element may determine whether to perform positioning verification for the UE based on the location identification information of the UE.

In other embodiments, the first network element may determine whether to perform positioning verification for the UE based on a satellite link indication and location identification information of the UE, wherein the satellite link indication is used to indicate whether 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 first network element may determine to perform positioning verification for the UE based on a satellite link indication and location identification information of the UE, wherein the satellite link indication is used to indicate that 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 first network element may determine not to perform positioning verification for the UE based on a satellite link indication and location identification information of the UE, wherein the satellite link indication 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 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 first network element may determine whether to perform positioning verification for the UE based on the satellite link indication and the location identification information of the UE.

In some embodiments, the first network element may include at least one of a session management function (SMF, session management function) network element and an access and mobility management function (AMF, access and mobility management function) network element.

As shown in FIG. 2 , the confirmation method for the UE positioning verification includes the following steps:

S201, based on the positioning verification indication, determine whether to perform positioning verification for the UE.

In this embodiment, the location verification indication may come from the second network element. For example, when the first network element is an SMF network element, the location verification indication may come from a policy control function (PCF, policy control function) network element. When the first network element is an AMF network element, the location verification indication may come from a PCF network element or an SMF network element. The location verification indication may be obtained by the second network element 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. The second network element may determine whether to perform positioning verification for the UE based on the positioning verification information, and send a positioning verification indication to the first network element when it is determined to perform positioning verification. Wherein, for the manner in which the second network element obtains the positioning verification indication based on the positioning verification information, reference may be made to the above description of whether the first network element determines whether to perform positioning verification for the UE based on the positioning verification information.

Specifically, the second network element may be obtained based on the location verification information and a preconfigured policy in the second network element.

The second network element may determine whether to perform positioning verification for the UE based on the positioning verification information and a policy preconfigured in the second network element, and send a positioning verification indication to the first network element when determining to perform positioning verification.

That is, the first network element may receive the positioning verification indication from the second network element and determine whether to perform positioning verification for the UE based on the positioning verification indication. In some embodiments, the first 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 first 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 first 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, ie 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.

In the embodiment of the present disclosure, the network device can determine whether to perform positioning verification for the UE based on the positioning verification indication, thereby making up for the lack of how to determine whether to perform the UE positioning verification in the prior art.

FIG. 3 shows a schematic flowchart of a method for confirming UE positioning verification according to an embodiment of the present disclosure. The method is executed by the SMF network element, thereby providing a confirmation method for performing positioning verification on the UE by the SMF network element. On the basis of the embodiment shown in FIG. 1 , as shown in FIG. 3 , the confirmation method for the UE positioning verification includes the following: step:

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

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.

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.

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.

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.

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.

The positioning verification indication information includes a positioning verification indication indicating that positioning verification is performed, and is sent by the PCF network element when it is determined to perform positioning verification for the UE.

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.

In some embodiments, the location verification indication information is carried in a session management (SM, session management) policy association establishment response or an SM policy association modification response, and is sent by the PCF network element to the SMF network element.

In this embodiment, the PCF network element may send the location verification indication information to the SMF network element through the SM policy association establishment response or the SM policy association modification response. Specifically, the location verification indication information may be carried in the SM policy association establishment response or the SM policy association modification response.

The PCF network element may send a time period for performing positioning verification on the UE and a positioning verification instruction to the SMF network element, so as to instruct the SMF network element to perform positioning verification on 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.

In the embodiment of the present disclosure, the SMF network element may determine whether to perform positioning verification for the UE based on the positioning verification information and the pre-configured policy or may send the positioning verification information to the PCF network element so that the PCF network element based on the positioning verification information and the pre-configured policy Determining whether to perform positioning verification for the UE makes up for the lack of how to determine whether to perform the positioning verification of the UE in the prior art.

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.

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.

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 pre-configured 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 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. 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, the UE's location identification information and the pre-configured policy.

In some embodiments, the PCF 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 PCF 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 PCF 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.

The PCF 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 PCF network element indicates that UEs using satellite access and/or satellite links do not need a finer granularity than cell-level positioning granularity, then UE positioning verification does not need to be performed, and the PCF 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. Thus, the PCF network element may determine whether to perform location verification for the UE based on the satellite link indication and preconfigured policy indicating whether the UE is using satellite access and/or satellite backhaul.

In other embodiments, the PCF 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.

For example, the pre-configured policy in the PCF 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, if the UE's location identification information shows that the UE has not entered the mall, UE positioning verification may not be performed, and the PCF network element may determine not to perform positioning verification for the UE based on the UE's location identification information and a preconfigured policy. Therefore, the PCF network element may determine whether to perform positioning verification for the UE based on the UE's location identification information and a preconfigured policy.
