[0055] In order to better understand the method for reporting terminal device location information in a non-terrestrial network disclosed by the embodiments of the present application, the communication system used by the embodiments of the present application is described first.

[0056] Please refer to Figure 1 , Figure 1 is a schematic structural diagram of a communication system according to an embodiment of the present application.

Figure 1 The communication system shown takes one network side device 101 and one terminal device 102 as an example.

[0057] It should be noted that the technical solutions of the embodiments of the present application can be applied to an NTN communication system. NTN is an important technology introduced by 5G, which provides wireless resources through satellites (or unmanned aerial vehicles) instead of ground base stations.

The embodiments of the present application do not limit the specific technology and specific device form adopted by the network side device.

[0058] The terminal device 102 in the embodiments of the present application is an entity on the user side for receiving or transmitting signals, such as a mobile phone. The terminal device can also be referred to as user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc. The terminal device can be a car, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver function, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in transportation safety, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal device.

[0059] It can be understood that the communication system described in the embodiments of the present application is for more clearly illustrating the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided by the embodiments of the present application. It can be known by those skilled in the art that with the evolution of system architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0060] The method for reporting terminal device location information in a non-terrestrial network, the apparatus, the communication device, and the storage medium provided in the present application will be described in detail below with reference to the accompanying drawings.

[0061] Please refer to Figure 2 , Figure 2 is a flowchart of a method for reporting terminal device location information in a non-terrestrial network provided by an embodiment of the present application. It should be noted that the method for reporting terminal device location information in a non-terrestrial network of the present embodiment can be applied to a terminal device. That is, the method of the present embodiment can be described from the terminal device side. As shown in Figure 2 , the method for reporting terminal device location information in a non-terrestrial network can include but is not limited to the following steps.

[0062] Step S201, obtaining location information of a terminal device.

[0063] In one implementation, the terminal device can obtain location information with lower accuracy. Wherein, the accuracy is less than the accuracy of the positioning system in the terminal device, so as to ensure that the accurate location of the terminal device is not disclosed.

[0064] In another implementation, the terminal device can obtain location information after de-privacy. For example, after obtaining geographic coordinates through its own positioning system, the terminal device processes the geographic coordinates through a de-privacy processing method to obtain location information after de-privacy, which can ensure that the accurate location of the terminal device is not disclosed.

[0065] Step S202, reporting the location information of the terminal device to a network side device.

[0066] In one implementation, the terminal device can report the location information to the network side device based on the control information of the network side device. Wherein, in some embodiments, the control information of the network side device at least includes any one or more of the following: a location reporting indication sent by the network side device to the terminal device through dedicated signaling; a location reporting indication carried in system broadcast by the network side device; a periodic reporting of location information configured by the network side device for the terminal device through dedicated signaling; a range of areas provided by the network side device in system broadcast or dedicated signaling.

[0067] In other words, network-side devices can send location reporting instructions to terminal devices via dedicated signaling, and the terminal devices, upon receiving the instructions, report their own location information. Alternatively, network-side devices can carry location reporting instructions in system broadcasts, and the terminal devices report their location information after establishing an RRC (Radio Resource Control) connection. Alternatively, network-side devices can configure periodic location reporting for terminal devices via dedicated signaling, and this period can be provided to the terminal devices so that they can periodically report their location information. Alternatively, network-side devices can provide an area range in system broadcasts or dedicated signaling; if the terminal device's location is within the area range, the terminal device reports its location information; if the terminal device's location is outside the area range, the terminal device does not report its location information. As an example, the area range can be defined by multiple coordinate points or by a reference point and radius; this application does not specifically limit this.

[0068] By implementing the embodiments of this application, the location information of the terminal device can be reported to the network-side device, enabling the network side to provide appropriate services to the terminal device based on the reported location, including selecting the local operator core network node, thereby ensuring normal communication between the terminal device and the NTN network.

[0069] To address the issue of potential privacy violations associated with terminal devices reporting their location, terminal devices can report their location with lower precision. For example, they can report their location to the network-side device after removing privacy concerns. As an example, the location information reported to the network-side device can include, but is not limited to, any of the following: region identifier; offset location information; anchor point identifier. In other words, the terminal device can report its region identifier, its offset location information, or its anchor point identifier to the network-side device to achieve location reporting.

[0070] It should be noted that the location information reported to the network-side device can be privacy-deprecated location information. The "area identifier, offset location information, or anchor point identifier" given above are several examples for the convenience of understanding this application. In addition to the "area identifier, offset location information, or anchor point identifier" given above, the privacy-deprecated location information can also be other forms of information, and this application does not make specific limitations on this.

[0071] It should also be noted that the method of obtaining location information will vary depending on the content of the location information reported to the network-side device. The following will describe how terminal devices report their own location in non-terrestrial networks from three aspects: location information including area identifier, offset location information, or anchor point identifier.

[0072] Please see Figure 3 , Figure 3 This is a flowchart illustrating a method for reporting terminal device location information in a non-terrestrial network, as provided in an embodiment of this application. It should be noted that the method for reporting terminal device location information in a non-terrestrial network according to this application embodiment can be applied to the terminal device. In other words, the method in this application embodiment can be described from the perspective of the terminal device.

[0073] In this embodiment, the location information includes a region identifier; that is, in this embodiment, the region identifier of the terminal device is reported to the network-side device. Figure 3 As shown, the method for reporting the location information of terminal devices in this non-terrestrial network may include, but is not limited to, the following steps.

[0074] Step S301: Obtain the region identifier of the terminal device.

[0075] Optionally, the region identifier can be obtained from the length and width of the region, as well as the longitude and latitude lengths of the terminal device's own geographic coordinates. As an example, obtain the geographic coordinates of the terminal device, obtain the length and width of the region, and obtain the region identifier of the terminal device based on the longitude and latitude lengths of the geographic coordinates, the length and width of the region.

[0076] In one implementation, a first value can be obtained based on the longitude length of the geographic coordinates and the length of the region, and a second value can be obtained based on the latitude length of the geographic coordinates and the width of the region. The region identifier of the terminal device can then be obtained based on the first and second values. For example, the terminal device can take the quotient of the longitude length of the geographic coordinates and the length of the region, using the quotient as the first value; take the quotient of the latitude length of the geographic coordinates and the width of the region, using the quotient as the second value; and combine the first and second values ​​to obtain the region identifier of the terminal device.

[0077] It should be noted that the geographical coordinates in this embodiment can be either absolute or relative geographical coordinates. In one optional implementation, when the geographical coordinates are relative geographical coordinates, the relative geographical coordinates of the terminal device relative to the network-side device can be calculated using the absolute geographical coordinates, and these relative geographical coordinates can be used as the geographical coordinates of the terminal device.

[0078] For example, the above-mentioned method for obtaining the geographic coordinates of a terminal device can be implemented as follows: obtain the absolute geographic coordinates of the terminal device; based on the absolute geographic coordinates, obtain the relative geographic coordinates of the terminal device relative to the origin; where the origin is the absolute geographic coordinates configured by the network-side device. That is, when using relative geographic coordinates, the origin is the absolute geographic coordinates configured by the network-side device (such as a base station), and the terminal device calculates its relative geographic coordinates relative to the origin based on its own absolute geographic coordinates.

[0079] In one alternative implementation, when the quotient of the longitude of the geographic coordinates and the length of the region has a remainder, and / or when the quotient of the latitude of the geographic coordinates and the width of the region has a remainder, the quotient result can be rounded up, or the quotient result can be rounded down.

[0080] As an example, the length and width of the area can be the same. Additionally, in some embodiments of this application, the length and width of the area can be configured by the network, specified by a protocol, or provided by pre-configuration. For example, the length and width of the area can be configured by the network-side device, or specified by a communication protocol; or the length and width of the area can be pre-configured by the terminal device at the factory.

[0081] Step S302: Report the area identifier of the terminal device to the network side device.

[0082] In the embodiments of this application, step S302 can be implemented in any of the ways described in the embodiments of this application. The embodiments of this application do not limit this, nor will they be described in detail.

[0083] By implementing the embodiments of this application, the region identifier of the terminal device can be calculated using the length and width of the region, as well as the longitude and latitude lengths of the terminal device's own geographical coordinates. This region identifier can then be reported to the network-side device as the location of the terminal device, thereby ensuring that the true and accurate location of the terminal device is not leaked and that the privacy of the terminal device is not violated.

[0084] To further ensure normal communication between the terminal device and the network, when the terminal device changes location, it can report the updated area identifier to the network-side device. In some embodiments according to this application, such as... Figure 3 As shown, the method for reporting the location information of terminal devices in the non-terrestrial network may further include step S303.

[0085] Step S303: In response to a change in the area identifier of the terminal device, the updated area identifier is reported to the network-side device.

[0086] In other words, when the area identifier of a terminal device changes, it indicates that the location of the terminal device has changed. The terminal device can report the updated area identifier to the network-side device to ensure normal communication between the terminal device and the network.

[0087] Optionally, in response to a change in the region identifier of the terminal device that persists for a first preset time period, the terminal device reports the updated region identifier to the network-side device. In other words, after the region identifier of the terminal device changes and persists for a certain period, the terminal device reports the updated region identifier to the network-side device.

[0088] One approach is to use a timer to determine whether the area identifier change has persisted for a certain period. In one implementation, when the terminal device's area identifier changes, a timer is started. During the timer's execution, if the terminal device returns to the area identifier before the timer started, the timer is stopped. If the timer expires, it indicates that the terminal device's area identifier has changed and persisted for a period of time. The terminal device then needs to re-report its location information, which means reporting the updated area identifier to the network-side device to ensure normal communication between the terminal device and the network.

[0089] Please see Figure 4 , Figure 4 This is a flowchart illustrating a method for reporting terminal device location information in a non-terrestrial network, as provided in an embodiment of this application. It should be noted that the method for reporting terminal device location information in a non-terrestrial network according to this application embodiment can be applied to the terminal device. That is, the method in this application embodiment can be described from the perspective of the terminal device. In this embodiment, the location information includes offset location information; that is, this application embodiment reports the offset location information of the terminal device to the network-side device. Figure 4 As shown, the method for reporting the location information of terminal devices in this non-terrestrial network may include, but is not limited to, the following steps.

[0090] Step S401: Obtain the offset position information of the terminal device.

[0091] Optionally, the offset position information can be obtained based on the offset and the position information of the terminal device. The method of obtaining the offset position information will also be different depending on the method of generating the offset.

[0092] In one implementation, the offset generated by the terminal device may include a first offset angle and a first offset length. Based on the generated first offset angle and first offset length, the terminal device obtains the offset position information of the terminal device using the polar coordinate system method with the absolute geographical location of the terminal device as the pole.

[0093] As an example, the terminal device can generate a first random angle value between a first angle and a first maximum angle, and use this first random angle value as the first offset angle; it can also generate a first random length value between a first length and a first maximum length, and use this first random length value as the first offset length. For example, taking a first angle of 0 degrees, a first maximum angle of 360 degrees, and a first length of 0 as an example, the terminal device can randomly generate an angle between 0 and 360 degrees, and use this angle as the first offset angle; it can also randomly generate a value between 0 and the first maximum length, and use this value as the first offset length. The terminal device can obtain its offset position information using a polar coordinate system based on the first offset angle and the first offset length. Here, the pole of the polar coordinate system represents the absolute geographical location of the terminal device, and the polar axis of the polar coordinate system can be a parallel of latitude, a parallel of latitude, or another direction specified by the protocol. Furthermore, the first maximum length can be configured by the network, specified by the protocol, or pre-configured by the terminal device at the factory.

[0094] In another implementation, the offset generated by the terminal device may include a second offset angle. Based on the generated second offset angle and a preset second offset length, the terminal device obtains its offset position information using a polar coordinate system, with the terminal device's absolute geographical location as the pole.

[0095] As an example, the terminal device can generate a second random angle value between the second angle and the second maximum angle, and use this second random angle value as the second offset angle. For example, taking a second angle of 0 degrees and a second maximum angle of 360 degrees as an example, the terminal device can randomly generate an angle between 0 and 360 degrees, and use this angle as the second offset angle. Based on this second offset angle and a preset second offset length, the terminal device can obtain its offset position information using a polar coordinate system, with the terminal device's absolute geographical location as the pole. The polar axis of the polar coordinate system can be a parallel of latitude, a parallel of latitude, or another direction specified by the protocol. Furthermore, the second offset length can be configured by the network, specified by the protocol, or pre-configured by the terminal device at the factory.

[0096] In another implementation, the offset generated by the terminal device may include the offset longitude length and the offset latitude length. The terminal device obtains its offset position information based on the generated offset longitude length, offset latitude length, and the terminal device's geographical coordinates.

[0097] As an example, the terminal device generates a second random length value between the second length and the second maximum length, and uses this second random length value as the offset longitude length; it also generates a third random length value between the third length and the third maximum length, and uses this third random length value as the offset latitude length. For example, with the second length and the third length both being 0, the terminal device can randomly generate a value between 0 and the second maximum length, using this value as the offset longitude length, and also randomly generate a value between 0 and the third maximum length, using this value as the offset latitude length. The terminal device's geographic location coordinates are summed with the offset longitude length and the offset latitude length. For example, the longitude coordinates in the geographic location coordinates are summed with the offset longitude length, and the latitude coordinates in the geographic location coordinates are summed with the offset latitude length. The array formed by these two sums serves as the offset position information of the terminal device.

[0098] In one alternative implementation, the third maximum length can be the maximum width. The second maximum length and the maximum width can be the same. It should be noted that the second and third maximum lengths can be configured by the network, specified by the protocol, or provided by the terminal device pre-configured at the factory.

[0099] Step S402: Report the offset position information of the terminal device to the network side device.

[0100] In the embodiments of this application, step S402 can be implemented in any of the ways described in the embodiments of this application. The embodiments of this application do not limit this, nor will they be described in detail.

[0101] By implementing the embodiments of this application, the offset angle and offset length generated by the terminal device can be used to obtain the offset position information of the terminal device according to the polar coordinate system, with the absolute geographical location of the terminal device as the pole. This offset position information is then reported to the network-side device as the location of the terminal device, ensuring normal communication between the terminal device and the network while also preventing the leakage of the terminal device's true and accurate location and protecting its privacy.

[0102] To further ensure normal communication between the terminal device and the network, when the terminal device changes location, it can report the updated offset location information to the network-side device. In some embodiments according to this application, such as... Figure 4 As shown, the method for reporting the location information of terminal devices in the non-terrestrial network may further include step S403.

[0103] Step S403: In response to a change in the location of the terminal device, and the distance between the updated location information and the previously reported location information is greater than a threshold value, the updated location information is reported.

[0104] In other words, when the location of a terminal device changes and is updated, and the distance between the updated location information and the location information reported last time is greater than a threshold, it indicates that the location of the terminal device has changed and it needs to report the updated location information to the network side device to ensure normal communication between the terminal device and the network.

[0105] Optionally, in response to a change in the location of the terminal device, and if the distance between the updated location information and the previously reported location information is greater than a threshold value and continues for a second preset time period, the updated location information is reported to the network-side device.

[0106] In other words, when the location of a terminal device changes and is updated, and the distance between the updated location and the previously reported location exceeds a threshold for a sustained period, the terminal device will report the updated offset location information to the network-side device. A timer can be used to determine whether the location change has persisted for a certain period. In one implementation, when the terminal device's location changes and is updated, and the distance between the updated location and the previously reported location exceeds a threshold, a timer is started. During the timer's operation, if the distance between the terminal device and the previously reported offset location is less than the threshold, the timer is stopped. If the timer times out, it indicates that the terminal device's location has changed and is updated, and the distance between the updated location and the previously reported location exceeds the threshold for a sustained period. The terminal device then needs to re-report its location information, i.e., report the updated offset location information to the network-side device, to ensure normal communication between the terminal device and the network.

[0107] In one implementation, when the location of the terminal device changes and is updated, and the distance between the updated location information and the previously reported location information exceeds a threshold, the updated location information reported to the network-side device can be calculated using a new offset. Alternatively, it can be calculated using the offset generated during the previous location report. In other words, when the terminal device reports offset location information to the network-side device, if the terminal device's location changes, updated location information needs to be reported to the network-side device. This updated location information can be calculated using a newly generated offset by the terminal device, or it can be calculated using the offset generated during the previous location report.

[0108] Please see Figure 5 , Figure 5This is a flowchart illustrating a method for reporting terminal device location information in a non-terrestrial network, as provided in an embodiment of this application. It should be noted that the method for reporting terminal device location information in a non-terrestrial network according to this application can be applied to the terminal device. That is, the method in this application can be described from the perspective of the terminal device. In this embodiment, the location information includes an anchor point identifier; that is, this embodiment reports the anchor point identifier of the terminal device to the network-side device. Figure 5 As shown, the method for reporting the location information of terminal devices in this non-terrestrial network may include, but is not limited to, the following steps.

[0109] Step S501: Obtain the anchor point identifier of the terminal device.

[0110] Optionally, the anchor point identifier can be obtained by calculating the coordinates of the nearest anchor point to the terminal device. As an example, the distances between the terminal device and at least one anchor point are calculated, and the nearest anchor point is obtained from the at least one anchor point. The anchor point identifier of the nearest anchor point is used as the anchor point identifier of the terminal device. Optionally, the anchor point identifier and anchor point coordinates can be sent to the terminal device by the network-side device. For example, when the terminal device establishes a connection with the network-side device, the network-side device can send an anchor point sequence to the terminal device, wherein the anchor point sequence includes at least one anchor point identifier and the anchor point coordinates corresponding to the anchor point identifier. The terminal device can calculate its own distance to the anchor point coordinates and use the nearest anchor point identifier as the anchor point identifier of the terminal device.

[0111] Step S502: Report the anchor point identifier of the terminal device to the network side device.

[0112] In the embodiments of this application, step S502 can be implemented in any of the embodiments of this application. The embodiments of this application do not limit this and will not be described in detail.

[0113] In one implementation, the distance of the terminal device from the nearest anchor point can also be reported to the network-side device. That is, the nearest anchor point is found, and the anchor point identifier of the nearest anchor point is reported as the location of the terminal device to the network-side device. The distance of the terminal device from the nearest anchor point can also be reported.

[0114] By implementing the embodiments of this application, the identifier of the anchor point closest to the terminal device, calculated from the calculation, can be used as the location of the terminal device and reported to the network-side device. This enables the network to provide appropriate services based on the different locations of the terminal device, thereby ensuring that the true and accurate location of the terminal device is not disclosed and that the privacy of the terminal device is not violated.

[0115] To further ensure normal communication between the terminal device and the network, when the terminal device changes location, it can report the updated anchor point identifier to the network-side device. In some embodiments according to this application, such as... Figure 5 As shown, the method for reporting the location information of terminal devices in the non-terrestrial network may further include step S503.

[0116] Step S503: In response to a change in the anchor point of the terminal device, the updated anchor point identifier is reported to the network-side device.

[0117] In other words, when the nearest anchor point to the terminal device changes, it indicates that the terminal device's location has changed. The terminal device can then report the updated anchor point identifier to the network-side device to ensure normal communication between the terminal device and the network.

[0118] Optionally, in response to a change in the nearest anchor point to the terminal device that persists for a third preset time period, the terminal device reports the updated anchor point identifier to the network-side device. In other words, after a change in the nearest anchor point to the terminal device persists for a certain period, the terminal device reports the updated anchor point identifier to the network-side device.

[0119] One approach is to use a timer to determine if the change in the nearest anchor point has persisted for a certain period. In one implementation, when the nearest anchor point to the terminal device changes (e.g., from nearest anchor point 1 to nearest anchor point 2), a timer is started. During the timer's operation, if the nearest anchor point to the terminal device becomes the same as the anchor point in the last report, the timer is stopped. If the timer expires, it indicates that the nearest anchor point to the terminal device has changed and persisted for a certain period. The terminal device then needs to re-report its location information, which involves reporting the updated anchor point identifier to the network-side device to ensure normal communication between the terminal device and the network.

[0120] It is understood that the above embodiments describe the implementation of the method for reporting terminal device location information in a non-terrestrial network from the terminal device side. This application also proposes another method for reporting terminal device location information in a non-terrestrial network. The implementation of this method from the network side will be described below. Please refer to... Figure 6 , Figure 6 This is a flowchart illustrating another method for reporting terminal device location information in a non-terrestrial network, as provided in an embodiment of this application. It should be noted that the method for reporting terminal device location information in a non-terrestrial network according to this application embodiment can be applied to network-side devices. That is, the method in this application embodiment can also be described from the perspective of network-side devices. Figure 6 As shown, the method for reporting the location information of terminal devices in this non-terrestrial network may include, but is not limited to, the following steps.

[0121] Step S601: Receive location information reported by the terminal device.

[0122] In this embodiment, the terminal device can obtain location information with lower precision and report the obtained location information to the network-side device, so that the network-side device can receive the location information reported by the terminal device and provide appropriate services to the terminal device based on the location information.

[0123] In another implementation, the terminal device can obtain privacy-degraded location information. For example, after obtaining geographic coordinates through its own positioning system, the terminal device processes these geographic coordinates using a privacy-degraded method to obtain privacy-degraded location information. This location information is then reported to the network-side device, enabling the network-side device to receive the location information reported by the terminal device and provide appropriate services to the terminal device based on this location information.

[0124] To address the issue of potential privacy violations associated with terminal devices reporting their own locations, terminal devices can report their locations with lower precision. For example, they can report their location to the network-side device after removing privacy concerns. As an example, the location information reported to the network-side device should include at least one of the following: a region identifier; offset location information; or an anchor point identifier. In other words, the terminal device can report its region identifier, its offset location information, or its anchor point identifier to the network-side device to achieve location reporting.

[0125] It should be noted that the location information reported to the network-side device can be privacy-deprecated location information. The "area identifier, offset location information, or anchor point identifier" given above are several examples for the convenience of understanding this application. In addition to the "area identifier, offset location information, or anchor point identifier" given above, the privacy-deprecated location information can also be other forms of information, and this application does not make specific limitations on this.

[0126] It should also be noted that the method of obtaining location information will differ depending on the content of the location information reported to the network-side device. For details on how terminal devices obtain their own location information, please refer to the above. Figures 3 to 5 The embodiments shown are described herein, but this application does not limit them, and will not repeat them further.

[0127] In one implementation, the network-side device can send control information to the terminal device and receive location information reported by the terminal device based on the control information. That is, the network-side device can send control information to the terminal device so that the terminal device can report its own location information based on the control information. In some embodiments, the control information of the network-side device includes at least one or more of the following: a location reporting instruction sent by the network-side device to the terminal device via dedicated signaling; a location reporting instruction carried by the network-side device in system broadcast; periodic location information configured by the network-side device for the terminal device via dedicated signaling; and a regional range provided by the network-side device in system broadcast or dedicated signaling.

[0128] In other words, network-side devices can send location reporting instructions to terminal devices via dedicated signaling, and the terminal devices, upon receiving the instructions, report their own location information. Alternatively, network-side devices can carry location reporting instructions in system broadcasts, and the terminal devices report their location information after establishing an RRC connection. Alternatively, network-side devices can configure the terminal devices to periodically report location information via dedicated signaling, and this period can be provided by the network-side devices to the terminal devices so that they can periodically report their own location information. Alternatively, network-side devices can provide a region range in system broadcasts or dedicated signaling; if the terminal device's location is within this region, the terminal device reports its location information; if the terminal device's location is not within this region, the terminal device does not report its location information. As an example, this region range can be defined by multiple coordinate points or by a reference point and radius; this application does not specifically limit this.

[0129] By implementing the embodiments of this application, the terminal device can report its own location to the network side device, so that the network side can provide appropriate services to the terminal device based on the reported location, including selecting the local operator core network node, thereby ensuring normal communication between the terminal device and the NTN network.

[0130] In the embodiments provided above, the methods provided by the embodiments of this application have been described from the perspectives of terminal devices and network-side devices, respectively. To implement the functions of the methods provided in the embodiments of this application, the terminal device and the network-side device may include hardware structures and software modules, implementing the above functions in the form of hardware structures, software modules, or a combination of hardware structures and software modules. One of the above functions can be executed in the form of hardware structures, software modules, or a combination of hardware structures and software modules.

It should be noted that the device in this embodiment can be a terminal device, a device within a terminal device, or a device compatible with a terminal device. Figure 7 The apparatus 700 for reporting terminal device location information in a non-terrestrial network may include an acquisition module 701 and a transceiver module 702. The transceiver module may be a transceiver or a communication interface.

[0146] Optionally, the transceiver module 702 is specifically used to: in response to a change in the location of the terminal device, and when the distance between the updated location information and the location information at the time of the last report is greater than a threshold value and continues for a second preset time period, report the updated location information to the network-side device.

[0147] In some embodiments of this application, the acquisition module 701 is specifically used to: calculate the distance between the terminal device and at least one anchor point; acquire the nearest anchor point from the at least one anchor point; and use the anchor point identifier of the nearest anchor point as the anchor point identifier of the terminal device.
