[0002] With the continuous development of Internet of Things applications, in the complex scenario of connecting all things, there are more and more applications for terminal location information.

[0003] In related technologies, in a satellite communication network, location information reporting can be triggered according to the timing advance (TA) compensation value TTA corresponding to a terminal device, or the change amount of the specific timing advance TA of the terminal device. Among them, the specific TA of the terminal device is the TA between the terminal device and the satellite, that is, the service link timing advance TA, which is equal to the common pre-compensation TTA - common TA. However, this method of triggering location information reporting has the phenomenon of frequently triggering location information reporting, resulting in waste of resources.

[0044] Here, exemplary embodiments will be described in detail, and examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0045] For ease of understanding, first, the terms related to the present disclosure are introduced.

[0046] 1. Non-Terrestrial Networks (NTN)

[0047] The non-terrestrial network is a global seamless coverage integrated communication network that combines satellite communication systems with 5G to complement each other, meeting various business needs of users everywhere. It is an important direction for future communication development.

[0048] 2. Timing Advance (TA)

[0049] Signals are delayed during spatial transmission. For example, if a terminal device moves away from the base station during a call, the signal sent from the base station will reach the terminal device "later and later", and at the same time, the signal of the terminal device will also reach the base station "later and later". Excessive delay will cause the signal of a certain terminal device received by the base station in this time slot to overlap with the time slot of the signal of another terminal device received by the base station in the next time slot, resulting in inter-symbol interference. Therefore, during data transmission, the uplink transmission of the terminal device requires a certain advance amount to ensure that the time intervals at which the uplink transmissions of different users reach the base station are less than a predefined threshold. The base station can send a timing advance command to the terminal device on the downlink channel, indicating the time for the terminal device to send in advance, and this time is the timing advance amount.

[0050] Please refer to Figure 1 ,Figure 1 Schematic diagram of the architecture of a communication system provided by an embodiment of the present disclosure. The communication system may include, but is not limited to, a network device and a terminal device. Figure 1 The number and form of the devices shown are only for illustration and do not constitute a limitation to the embodiments of the present disclosure. In practical applications, it may include two or more network devices and two or more terminal devices.

The embodiments of the present disclosure do not limit the specific technologies and specific device forms adopted by the terminal device.

[0054] It can be understood that the communication system described in the embodiments of the present disclosure is to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art know that with the evolution of the system architecture and the emergence of new service scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0055] Generally, when the change amount of the timing advance (TA) compensation value TTA corresponding to the terminal device, or the change amount of the TA of the serving link of the terminal device exceeds a certain threshold, the location information reporting is triggered. When the terminal device moves, or the satellite moves, it may cause a change in TA and trigger the location information reporting. This is contrary to the original intention of introducing the TA reporting based on the location information of the terminal device. The reason why we introduce the location information reporting is that through the location information of the terminal device, the network can calculate the round-trip time (RTT) between the terminal device and the satellite, and thus, based on this round-trip time, perform uplink scheduling without the terminal device reporting TA frequently. Therefore, it is necessary to modify the triggering condition to exclude the factor of satellite movement. The following will introduce in detail a method and device for reporting location information provided by the present disclosure with reference to the accompanying drawings.

[0056] Please refer to Figure 2 , Figure 2 which is a schematic flowchart of a method for reporting location information provided by an embodiment of the present disclosure, and this method is executed by a terminal device. As Figure 2 shown, this method may include but is not limited to the following steps:

[0057] Step 201, determine that the timing advance (TA) change value corresponding to the terminal device is greater than a threshold value, where the TA change is caused by the position change of the terminal device.

[0058] In the present disclosure, considering that in the NTN network, due to the large coverage area of satellites, the network device needs to know the location information of the terminal device to select a suitable access and mobility management function (AMF) for the terminal device. Therefore, the terminal device needs to report its location information when meeting the trigger condition or periodically. However, due to the movement of the terminal device or the satellite, it may cause the terminal device to meet the trigger condition for reporting location information, resulting in waste of resources. To avoid the phenomenon that the terminal device does not move, but only due to the movement of the satellite, the TA change value is greater than the threshold value and triggers the reporting of location information, the present disclosure can eliminate the influence of satellite movement on the TA change value, only retain the TA change value caused by the position change of the terminal device, and report the location information of the terminal device to the network device when the TA change value corresponding to the terminal device caused by its own position change is greater than the threshold value.

[0059] In the present disclosure, after obtaining the location information, the terminal device can determine the TA change value according to the current location information, or the previous reported location information, and the current satellite location information, or the satellite location corresponding to the previous reported location information. Then, the TA change value can be compared with a preset threshold value.

[0060] Step 202, report the location information of the terminal device to the network device.

[0061] In the present disclosure, when the TA change value corresponding to the terminal device is greater than the threshold value, it can be determined that the position of the terminal device has changed and the reporting condition of the location information is met. At this time, the terminal device can report the location information of the terminal device to the network device. Thus, the network device can calculate the round-trip time (RTT) between the terminal device and the satellite according to the location information reported by the terminal device.

[0062] Optionally, when it is determined that the current TA change value is less than or equal to the threshold value, reporting the location information to the network device is not triggered.

[0063] Optionally, the terminal device may report location information only when there is available location information, where the location information may be commonLocationInfo, bt-LocationInfo, wlan-LocationInfo, sensor-LocationInfo, etc.

[0064] Optionally, when the network device indicates the configuration information for reporting location information through a connection reconfiguration message, the terminal device may configure the location information in the test report corresponding to the reportconfig IE of the configuration information. Thus, the network device can determine the location information of the terminal device based on the test report.

[0065] In the present disclosure, after the terminal device determines that the timing advance TA change value caused by the location change of the terminal device corresponding to the terminal device is greater than the threshold, the terminal device reports the location information of the terminal device to the network device. Thus, the terminal device reports location information only when the TA change value caused by its own location change is greater than the threshold, thereby avoiding the phenomenon of reporting location information triggered by satellite movement and effectively avoiding waste of resources.

[0066] Please refer to Figure 3 , Figure 3 which is a schematic flowchart of a method for reporting location information provided by an embodiment of the present disclosure, and this method is executed by the terminal device. As Figure 3 shown, this method may include but is not limited to the following steps:

[0067] Step 301, determine a first TA value according to the first location information currently corresponding to the terminal device and the second location information currently corresponding to the satellite.

[0068] Among them, since the first TA value is determined according to the location of the terminal device and the location of the satellite, the first TA value is the TA value corresponding to the service link, that is, the specific timing advance TA value unique to the terminal device.

[0069] In the present disclosure, the terminal device may determine the second location information currently corresponding to the satellite according to the ephemeris corresponding to the satellite, or may also determine the second location information according to the indication of other terminal devices or network devices. The present disclosure does not make any limitation thereto.

[0070] Step 302, determine a second TA value according to the third location information reported by the terminal device last time and the second location information.

[0071] In the present disclosure, when the terminal device reports location information, it can record the location information of the corresponding terminal device and the location information of the satellite. Then, at the current moment, based on the third location information of the terminal device reported previously and the second location information of the current satellite that are recorded, the second TA value can be calculated.

[0072] Step 303: Determine the TA change value according to the difference between the first TA value and the second TA value.

[0073] In the present disclosure, the first TA value and the second TA value can be subtracted from each other, and then this difference value can be determined as the TA change value corresponding to the terminal device.

[0074] Step 304: Determine that the timing advance TA change value corresponding to the terminal device is greater than the threshold value.

[0075] Step 305: Report the location information of the terminal device to the network device.

[0076] In the present disclosure, for the specific implementation process of steps 304 - 305, reference can be made to the detailed description of any embodiment of the present disclosure, which will not be elaborated herein.

[0077] It can be understood that since the TA value corresponding to the service link can represent the distance between the terminal device and the satellite, in the present disclosure, based on the second location information of the current satellite and the location information of the terminal device before and after movement respectively, the TA values corresponding to the two service links are determined, and then the TA change value is determined. Since this TA change value is determined based on the same location information of the satellite, that is, the change of the satellite's location is not considered, when determining whether the location information reporting condition is satisfied, only the change of the terminal device's location is considered, and the change of the satellite's location is not considered, effectively avoiding the waste of resources caused by the reporting of location information triggered only by the change of the satellite's location while the terminal device's location remains unchanged.

[0078] In the present disclosure, the terminal device can determine the first TA value according to the current first location information corresponding to the terminal device and the current second location information corresponding to the satellite, and determine the second TA value according to the third location information reported previously by the terminal device and the second location information. Then, according to the difference between the first TA value and the second TA value, the TA change value can be determined. When the timing advance TA change value corresponding to the terminal device is greater than the threshold value, the location information of the terminal device can be reported to the network device. Thus, by determining the TA change value based on the current location information of the satellite and the location information of the terminal device before and after movement, the part of the TA change value caused by the movement of the satellite is effectively eliminated, thereby avoiding the phenomenon of reporting location information triggered only by the movement of the satellite and effectively avoiding the waste of resources.

[0079] Please refer to Figure 4 , Figure 4It is a schematic flowchart of a method for reporting location information provided by an embodiment of the present disclosure, and this method is executed by a terminal device. As Figure 4 shown, this method may include but is not limited to the following steps:

[0080] Step 401, determine a first TA compensation value according to the first location information currently corresponding to the terminal device and the second location information currently corresponding to the satellite.

[0081] In the present disclosure, during the random access process, when a terminal sends a preamble after a random access channel (RACH) opportunity, the network needs to know the corresponding transmission opportunity when receiving the preamble, so as to correctly address the random access request during the random access response and perform uplink timing adjustment. However, in a satellite communication system, the round-trip delay difference between different terminals reaching the base station can be up to 10.3 ms. When the interval between opportunities is less than the maximum round-trip delay difference, the preamble reception windows of different opportunities overlap, and the base station cannot infer the transmission opportunity subframe and uplink timing deviation of the received preamble. For the above preamble reception ambiguity problem, it can be solved by TA pre-compensation, that is, before sending the preamble, the terminal device advances the timing of the uplink (UL) of the terminal device according to the RTT between the terminal and the base station, so as to ensure that the time difference between the preambles sent by different terminal devices at the same opportunity reaching the base station is limited within 1 subframe.

[0082] In the present disclosure, the terminal device may determine the second location information currently corresponding to the satellite according to the ephemeris corresponding to the satellite, or may also determine the second location information according to the indication of other terminal devices or network devices. The present disclosure does not make any limitation in this regard.

[0083] In the present disclosure, while obtaining the current location information, the terminal device may determine the location information of the currently serving satellite, and determine the current location information of the terminal device as the first location information and the current location information of the satellite as the second location information. Then, according to the first location information currently corresponding to the terminal device and the second location information currently corresponding to the satellite, the first TA compensation value TTA can be calculated.

[0084] Generally, TTA may be equivalent to the RTT between the terminal device and the satellite plus the common TA, where the common TA is the RTT of the link between the satellite and the network device.

[0085] Step 402, determine a second TA compensation value according to the third location information reported by the terminal device last time and the second location information.

[0086] In the present disclosure, when the terminal device reports location information, it can record the location information of the corresponding terminal device and the location information of the satellite. Then, at the current moment, based on the third location information of the terminal device reported previously and the second location of the current satellite, the second TA compensation value can be calculated.

[0087] Step 403: Determine the TA change value according to the difference between the first TA compensation value and the second TA compensation value.

[0088] In the present disclosure, the first TA compensation value and the second TA compensation value can be subtracted from each other. Then, this difference value can be determined as the TA change value corresponding to the terminal device.

[0089] Step 404: Determine that the timing advance TA change value corresponding to the terminal device is greater than the threshold value.

[0090] Step 405: Report the location information of the terminal device to the network device.

[0091] In the present disclosure, for the specific implementation process of steps 404 - 405, reference can be made to the detailed description of any embodiment of the present disclosure, which will not be elaborated herein.

[0092] It can be understood that since the TA compensation value TTA can represent the distance between the terminal device and the satellite, in the present disclosure, based on the second location information of the current satellite and the location information of the terminal device before and after movement respectively, two TA compensation values are determined, and then the TA change value is determined. Since this TA change value is determined based on the same location information of the satellite, that is, the change of the satellite location is not considered, when determining whether the location information reporting condition is met, only the change of the terminal device location is considered, and the change of the satellite location is not considered, effectively avoiding the waste of resources caused by the reporting of location information triggered only by the change of the satellite location while the terminal device location remains unchanged.

[0093] In the present disclosure, the terminal device can determine the first TA compensation value according to the current first location information corresponding to the terminal device and the current second location information corresponding to the satellite, and determine the second TA compensation value according to the third location information reported previously by the terminal device and the second location information. Then, according to the difference between the first TA compensation value and the second TA compensation value, the TA change value can be determined. When the timing advance TA change value corresponding to the terminal device is greater than the threshold value, the location information of the terminal device is reported to the network device. Thus, by determining the TA change value based on the current location information of the satellite and the location information of the terminal device before and after movement, the part of the TA change value caused by the movement of the satellite is effectively eliminated, thereby avoiding the phenomenon of reporting location information triggered only by the movement of the satellite, and effectively avoiding the waste of resources.

[0094] Please refer toFigure 5 , Figure 5 is a schematic flowchart of a method for reporting location information provided by an embodiment of the present disclosure, and this method is executed by a terminal device. As Figure 5 shown, this method may include but is not limited to the following steps:

[0095] Step 501: Determine a third TA value according to the first location corresponding to the terminal device currently and the fourth location corresponding to the satellite at the previous time of reporting location information.

[0096] Among them, since the first TA value is based on the position of the terminal device and the position of the satellite, the first TA value is the TA value corresponding to the service link, that is, the specific timing advance TA value unique to the terminal device.

[0097] In the present disclosure, the terminal device may determine the current corresponding location information of the satellite according to the ephemeris corresponding to the satellite, or may also determine the location information according to the indication of other terminal devices or network devices. The present disclosure does not make any limitations in this regard.

[0098] In the present disclosure, when the terminal device reports location information, it may record the corresponding location information of the terminal device and the location information of the satellite. Then, at the current moment, the third TA value can be calculated according to the fourth location information of the satellite corresponding to the previously reported location information and the first location information corresponding to the current terminal device.

[0099] Step 502: Determine a fourth TA value according to the third location information and the fourth location information reported by the terminal device last time.

[0100] In the present disclosure, the terminal device may calculate the fourth TA value according to the third location information of the terminal device reported last time and the fourth location information of the satellite recorded at the current moment.

[0101] Step 503: Determine a TA change value according to the difference between the third TA value and the fourth TA value.

[0102] In the present disclosure, the third TA value and the fourth TA value can be subtracted from each other, and then this difference can be determined as the TA change value corresponding to the terminal device.

[0103] Step 504: Determine that the timing advance TA change value corresponding to the terminal device is greater than the threshold value.

[0104] Step 505: Report the location information of the terminal device to the network device.

[0105] In the present disclosure, for the specific implementation process of steps 504 - 505, reference may be made to the detailed description of any embodiment of the present disclosure, which will not be elaborated here.

[0106] It can be understood that since the TA value corresponding to the service link can represent the distance between the terminal device and the satellite, in the present disclosure, based on the fourth position information of the satellite corresponding to the previous reported location information, and the location information of the terminal device before and after movement, the TA values corresponding to the two service links are determined, and then the TA change value is determined. Since this TA change value is determined based on the same position information of the satellite, that is, the change in the position of the satellite is not considered, when determining whether the location information reporting condition is satisfied, only the change in the position of the terminal device is considered, and the change in the position of the satellite is not considered, effectively avoiding the reporting of location information triggered only by the change in the position of the satellite while the position of the terminal device remains unchanged, resulting in waste of resources.

[0107] In the present disclosure, the terminal device can determine the third TA value according to the first position corresponding to the terminal device currently and the fourth position information of the satellite corresponding to the previous reported location information, and determine the fourth TA value according to the third position information and the fourth position information reported by the terminal device previously. Then, the TA change value can be determined according to the difference between the third TA value and the fourth TA value. When the timing advance TA change value corresponding to the terminal device is greater than the threshold value, the location information of the terminal device is reported to the network device. Thus, by determining the TA change value based on the fourth position information of the satellite corresponding to the previous reported location information and the location information of the terminal device before and after movement, the part of the TA change value caused by the movement of the satellite is effectively excluded, thereby avoiding the phenomenon of reporting location information triggered only by the movement of the satellite, and effectively avoiding waste of resources.

[0108] Please refer to Figure 6 , Figure 6 which is a schematic flowchart of a method for reporting location information provided by an embodiment of the present disclosure, and this method is executed by the terminal device. As Figure 6 shown, the method may include but is not limited to the following steps:

[0109] Step 601, determine a third TA compensation value according to the first position corresponding to the terminal device currently and the fourth position information of the satellite corresponding to the previous reported location information.

[0110] In the present disclosure, during the random access process, after a terminal sends a preamble at a random access channel (RACH) opportunity, the network needs to know the corresponding transmission opportunity when receiving the preamble, so as to correctly address the random access request during the random access response and perform uplink timing adjustment. However, in a satellite communication system, the round-trip delay difference between different terminals reaching the base station can be up to 10.3 ms. When the interval between opportunities is less than the maximum round-trip delay difference, the preamble reception windows of different opportunities overlap, and the base station cannot infer the transmission opportunity subframe and uplink timing deviation of the received preamble. For the above preamble reception ambiguity problem, it can be solved by TA pre-compensation, that is, before the terminal device sends the preamble, the timing of the uplink (UL) of the terminal device is advanced according to the round-trip time (RTT) between the terminal and the base station, so as to ensure that the time difference between the preambles sent by different terminal devices at the same opportunity reaching the base station is limited within one subframe.

[0111] In the present disclosure, the terminal device can determine the current corresponding position information of the satellite according to the ephemeris corresponding to the satellite, or, alternatively, can also determine the position information according to the indication of other terminal devices or network devices. The present disclosure does not make any limitation thereto.

[0112] In the present disclosure, when reporting the position information, the terminal device can record the corresponding position information of the terminal device and the position information of the satellite, and then, at the current moment, can calculate the third TA compensation value TTA according to the fourth position information of the satellite corresponding to the previous reported position information and the first position information corresponding to the current terminal device.

[0113] Generally, TTA can be equivalent to the RTT between the terminal device and the satellite plus the common TA, where the common TA is the RTT of the link from the satellite to the network device.

[0114] Step 602: Determine a fourth TA compensation value according to the third position information and the fourth position information reported by the terminal device last time.

[0115] In the present disclosure, the terminal device can calculate the fourth TA compensation value according to the third position information and the fourth position information of the terminal device reported last time recorded at the current moment.

[0116] Step 603: Determine a TA change value according to the difference between the third TA compensation value and the fourth TA compensation value.

[0117] In the present disclosure, the third TA compensation value and the fourth TA compensation value can be subtracted from each other, and then this difference value can be determined as the TA change value corresponding to the terminal device.

[0118] Step 604: Determine that the timing advance (TA) change value corresponding to the terminal device is greater than the threshold value.

[0119] Step 605: Report the location information of the terminal device to the network device.

[0120] In the present disclosure, for the specific implementation process of steps 604 - 605, reference can be made to the detailed description of any embodiment of the present disclosure, which will not be elaborated here.

[0121] It can be understood that since the TA compensation value TTA can represent the distance between the terminal device and the satellite, the fourth position information of the satellite corresponding to the previous reported location information in the present disclosure, and the location information of the terminal device before and after movement are used to determine two TA compensation values, and then the TA change value is determined. Since this TA change value is determined based on the same position information of the satellite, that is, the change of the satellite position is not considered, when determining whether the location information reporting condition is satisfied, only the change of the terminal device position is considered, and the change of the satellite position is not considered, effectively avoiding the waste of resources caused by the reporting of location information triggered only by the change of the satellite position while the terminal device position remains unchanged.

[0122] In the present disclosure, the terminal device can determine the third TA compensation value according to the current first position corresponding to the terminal device and the fourth position of the satellite corresponding to the previous reported location information, and determine the second TA compensation value according to the third position information reported by the terminal device previously and the fourth position information of the satellite. Then, according to the difference between the third TA compensation value and the second TA compensation value, the TA change value is determined. When the timing advance (TA) change value corresponding to the terminal device is greater than the threshold value, the location information of the terminal device is reported to the network device. Thus, by determining the TA change value based on the fourth position information of the satellite corresponding to the previous reported location information and the location information of the terminal device before and after movement, the part of the TA change value caused by the movement of the satellite is effectively eliminated, thereby avoiding the phenomenon of reporting location information triggered only by the movement of the satellite and effectively avoiding the waste of resources.

[0123] Please refer to Figure 7 , Figure 7 which is a schematic flowchart of a method for reporting location information provided by an embodiment of the present disclosure, and this method is executed by the terminal device. As Figure 7 shown, this method may include but is not limited to the following steps:

[0124] Step 701: Receive the indication information sent by the network device, and the indication information is used to indicate the configuration information for the terminal device to report location information.

[0125] Among them, the configuration information may include any one of the following: description information of the TA change value, a periodic value of the reporting location information, and TA report configuration information based on a media access control control element (MAC CE).

[0126] In the present disclosure, the description information of the TA change value can be used to describe the specific meaning of the TA change value. The terminal device can determine how to determine the TA change value that triggers the reporting of location information through the description information of the TA change value. It can be understood that the TA change value determined according to the description information of the TA change value only considers the TA change brought about by the location change of the terminal device. That is, the form of determining the TA change value according to the description information of the TA change value can be the form described in any embodiment of the present disclosure, which will not be elaborated here.

[0127] Optionally, if the configuration information includes the description information of the TA change value, the configuration information may further include a threshold value, so that the terminal device can trigger the reporting of location information when it determines that the TA change value is greater than the threshold value according to the description information of the TA change value.

[0128] Optionally, when the configuration information of the reporting location information indicated by the network device includes a periodic value of the reporting location information, the terminal device can report the location information periodically according to this periodic value.

[0129] Optionally, when the configuration information of the reporting location information indicated by the network device includes TA report configuration information based on MAC CE, the terminal device can report the location information according to the TA report configuration information based on MAC CE.

[0130] Optionally, the network device can configure the configuration information of the reporting location information in the connection reconfiguration message, and the configuration information may include a reporting configuration reportconfig information element (IE), and configure the description information of the TA change value in the EventTriggerConfig IE of the reportconfig IE.

[0131] Optionally, the configuration information may further include a hysteresis hysteresis parameter, a trigger time timeToTrigger, etc. Thus, the terminal device can trigger the reporting of location information according to the indicated hysteresis parameter or timeToTrigger.

[0132] Step 702, when the configuration information includes the description information of the TA change value and a threshold value, the terminal device determines whether the current TA change value is greater than the threshold value.

[0133] Step 703: When it is determined that the current TA change value is greater than the threshold, report the location information of the terminal device to the network device.

[0134] Step 704: When it is determined that the current TA change value is less than or equal to the threshold, do not trigger reporting the location information to the network device.

[0135] In the present disclosure, for the specific implementation processes of steps 703 - 704, reference may be made to the detailed description of any embodiment of the present disclosure, which will not be elaborated herein.

[0136] In the present disclosure, after receiving the configuration information indication message sent by the network device for instructing the terminal device to report location information, the terminal device may report the location information of the terminal device to the network device when the timing advance (TA) change value corresponding to the terminal device is greater than the threshold. Thus, by determining the TA change value only based on the location change of the terminal device, the part of the TA change value caused by satellite movement is excluded, thereby avoiding the phenomenon of triggering location information reporting due to satellite movement and effectively avoiding waste of resources.

[0137] Please refer to Figure 8 , Figure 8 which is a schematic flowchart of a method for reporting location information provided by an embodiment of the present disclosure, and this method is executed by the network device. As Figure 8 shown, the method may include but is not limited to the following steps:

[0138] Step 801: Receive the location information of the terminal device sent by the terminal device, where the location information is sent by the terminal device when it is determined that the timing advance (TA) change value caused by the location change of the terminal device is greater than the threshold.

[0139] In the present disclosure, considering that in the NTN network, due to the large coverage area of satellites, the network device needs to know the location information of the terminal device to select a suitable access and mobility management function (AMF) for the terminal device, and thus the terminal device needs to report its location information when meeting the trigger condition or periodically. However, due to the movement of the terminal device or the movement of the satellite, it may cause the terminal device to meet the trigger condition for reporting location information, resulting in waste of resources. To avoid the phenomenon that the terminal device does not move but only due to the movement of the satellite, the TA change value is greater than the threshold, triggering the reporting of location information, the present disclosure can exclude the influence of satellite movement on the TA change value, only retain the TA change value caused by the location change of the terminal device, and report the location information of the terminal device to the network device when the timing advance (TA) change value corresponding to the terminal device caused by its own location change is greater than the threshold.

[0140] In the present disclosure, after the terminal device obtains the location information, it can determine the TA change value according to the current location information, or the previously reported location information, and the current satellite location information, or the satellite location corresponding to the previously reported location information. After that, it can compare the TA change value with a preset threshold value. When the TA change value corresponding to the timing advance of the terminal device is greater than the threshold value, it can be determined that the location of the terminal device has changed and the reporting condition of the location information is satisfied. At this time, the terminal device can report the location information to the network device. Thus, the network device can calculate the RTT between the terminal device and the satellite according to the location information reported by the terminal device.

[0141] Optionally, when it is determined that the current TA change value is less than or equal to the threshold value, reporting the location information to the network device is not triggered.

[0142] Optionally, the terminal device can report the location information only when there is available location information, where the location information can be commonLocationInfo, bt-LocationInfo, wlan-LocationInfo, sensor-LocationInfo, etc.

[0143] Optionally, when the network device indicates the configuration information for reporting the location information through a connection reconfiguration message, the terminal device can configure the location information in the test report corresponding to the reportconfig IE of the configuration information. Thus, the network device can determine the location information of the terminal device according to the test report.

[0144] In the present disclosure, the network device can receive the location information of the terminal device sent when it is determined that the TA change value caused by the location change of the terminal device is greater than the threshold value. Thus, the terminal device reports the location information only when the TA change value caused by its own location change is greater than the threshold value, thereby avoiding the phenomenon of reporting the location information triggered by the movement of the satellite and effectively avoiding the waste of resources.

[0145] Please refer to Figure 9 , Figure 9 which is a schematic flow chart of a method for reporting location information provided by an embodiment of the present disclosure, and this method is executed by the network device. As Figure 9 shown, this method may include but is not limited to the following steps:

[0146] Step 901, sending indication information to the terminal device, where the indication information is used to indicate the configuration information for the terminal device to report location information.

[0147] Among them, the configuration information may include any one of the following: description information of the TA change value, the periodic value of the reporting location information, and the TA report configuration information based on the media access control control element (MAC CE).

[0148] In the present disclosure, the description information of the TA change value can be used to describe the specific meaning of the TA change value. The terminal device can determine the TA change value that triggers the reporting of the location information based on the description information of the TA change value and how to determine it. It can be understood that the TA change value determined according to the description information of the TA change value only considers the TA change caused by the location change of the terminal device. That is, the form of the TA change value determined according to the description information of the TA change value can be the form described in any embodiment of the present disclosure, which will not be elaborated here.

[0149] Optionally, the description information of the TA change value may include: determining a first TA value from the first location information currently corresponding to the terminal device and the second location information currently corresponding to the satellite; determining a second TA value from the third location information reported by the terminal device last time and the second location information; determining the TA change value from the difference between the first TA value and the second TA value.

[0150] Optionally, the description information of the TA change value may include: determining a first TA compensation value from the first location information currently corresponding to the terminal device and the second location information currently corresponding to the satellite; determining a second TA compensation value from the third location information reported by the terminal device last time and the second location information; determining the TA change value from the difference between the first TA compensation value and the second TA compensation value.

[0151] Optionally, the description information of the TA change value may include: determining a third TA value from the first location currently corresponding to the terminal device and the fourth location of the satellite when the location information was reported last time; determining a fourth TA value from the third location information reported by the terminal device last time and the fourth location information; determining the TA change value from the difference between the third TA value and the fourth TA value.

[0152] Optionally, the description information of the TA change value may include: determining a third TA compensation value from the first location currently corresponding to the terminal device and the fourth location information of the satellite when the location information was reported last time; determining a fourth TA compensation value from the third location information reported by the terminal device last time and the fourth location information of the satellite; determining the TA change value from the difference between the third TA compensation value and the fourth TA compensation value.

[0153] Optionally, if the configuration information includes the description information of the TA change value, the configuration information may further include a threshold value. Thus, the terminal device can trigger the reporting of location information when it determines that the TA change value is greater than the threshold value according to the description information of the TA change value.

[0154] Optionally, when the configuration information for indicating the reporting of location information by the network device includes the periodic value for reporting location information, the terminal device can report location information periodically according to this periodic value.

[0155] Optionally, when the configuration information for indicating the reporting of location information by the network device includes the TA report configuration information based on MAC CE, the terminal device can report location information according to the TA report configuration information based on MAC CE.

[0156] Optionally, the network device can configure the configuration information for reporting location information in the connection reconfiguration message, and the configuration information may include the reportconfig information element (IE), and configure the description information of the TA change value in the EventTriggerConfig IE in the reportconfig IE.

[0157] Optionally, the configuration information may further include parameters such as hysteresis and timeToTrigger. Thus, the terminal device can trigger the reporting of location information according to the indicated hysteresis parameter or timeToTrigger.

[0158] Step 902: Receive the location information of the terminal device reported by the terminal device, where the location information is sent by the terminal device when it determines that the timing advance (TA) change value caused by the location change of the terminal device is greater than the threshold value.

[0159] In the present disclosure, for the specific implementation process of step 902, reference can be made to the detailed description of any embodiment in the present disclosure, which will not be elaborated here.

[0160] In the present disclosure, the network device can send indication information including the configuration information for indicating the terminal device to report location information to the terminal device, and then can receive the location information of the terminal device sent by the terminal device when it determines that the TA change value caused by the location change of the terminal device is greater than the threshold value. Thus, the terminal device only reports location information when the TA change value caused by its own location change is greater than the threshold value, thereby avoiding the phenomenon of triggering location information reporting due to satellite movement and effectively avoiding waste of resources.
