[0035] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0039] Figure 1 It is a schematic flow chart of a method for reporting location-related information according to an embodiment of the present disclosure. The method for reporting location-related information shown in this embodiment can be executed by a terminal, and the terminal includes but is not limited to a communication device such as a mobile phone, a tablet computer, a wearable device, a sensor, and an Internet of Things device. The terminal can communicate with a base station, and the base station includes but is not limited to a base station in a 4G, 5G, 6G, and other communication systems.

[0040] like Figure 1As shown, the method for reporting location-related information may include the following steps:

[0041] In step S101, reducing the accuracy of the location-related information of the terminal;

[0042] In step S102, the location-related information with reduced accuracy is reported to the base station.

[0043] In one embodiment, the terminal and the base station may communicate through a terrestrial network or through a non-terrestrial network (NTN). The technical solution of the present disclosure may be applicable to scenarios where the terminal and the base station communicate in a terrestrial network or in a non-terrestrial network. The following mainly illustrates the technical solution of the present disclosure in the scenario where the terminal and the base station communicate in a non-terrestrial network.

[0044] In a non-terrestrial network, a terminal can communicate with a base station via a satellite. For example, the base station transmits a signal to a satellite, and the satellite transmits a signal to the terminal. There are two main working modes of the satellite, one is a transparent transmission mode, and the other is a regeneration mode.

[0045] Since satellites move at high altitudes, their coverage is large and can even span several countries. The core networks of different countries may be different. For example, the access and mobility management functions (AMF) in the core networks are different. Therefore, for terminals within the satellite coverage, it is necessary to select the appropriate core network access for the terminal based on the terminal's location. In this case, the required accuracy for the terminal's location is generally not high, and an accuracy of 2 kilometers is sufficient.

[0046] Of course, in addition to this case, the present disclosure is also applicable to other situations where the location accuracy is not required to be high, and some embodiments may even not consider the network side's requirements for location accuracy.

[0047] According to the embodiments of the present disclosure, the terminal can determine its own location-related information and reduce the accuracy of the location-related information, and then report the location-related information with reduced accuracy to the base station, which is beneficial to preventing the base station and other network-side devices from obtaining location-related information with too high accuracy, thereby causing the privacy of the terminal user to be leaked.

[0048] In one embodiment, the location-related information includes at least one of the following:

[0049] Position coordinate information, timing advance TA (Timing Advance).

[0050] The TA may be an uplink TA pre-compensated by the terminal. In a non-terrestrial network, it is difficult for the network to determine the uplink TA of the terminal, so it is difficult for the network to compensate for the uplink TA. The terminal itself may pre-compensate the uplink TA.

[0051] In one embodiment, the triggering event for the terminal to report location-related information includes at least one of the following:

[0052] Timing advance reporting TA report, minimization of drive test MDT (Minimization of Drive-Test), self-organizing network SON (Self Organization Network, also known as self-optimizing network), base station indication reporting of location related information.

[0053] Among them, when the terminal is performing MDT, the terminal can carry the location-related information in the measurement report and send it to the base station in the connected state; when the terminal is performing SON, the terminal can carry the location-related information in the measurement report and send it to the base station in the connected state; when the terminal is performing pre-compensated TA, the terminal can send the location-related information to the base station; when the terminal receives an indication from the base station and determines that the location-related information needs to be reported, the terminal can also send the location-related information to the base station.

[0054] For the two cases where the triggering event is MDT or SON, the base station may carry the measurement configuration in the connection reconfiguration message, and may carry the event triggering configuration and / or periodic reporting configuration in the reporting configuration information element IE of the measurement configuration, and may carry an indication in the event triggering configuration or the periodic reporting configuration to instruct the terminal to report the location-related information. The terminal may report the location-related information based on the event configured in the event triggering configuration, or report the location-related information based on the period configured in the periodic reporting configuration.

[0055] The indication in the trigger configuration and / or the periodic report configuration may be carried in at least one of the following IEs, for example:

[0056] include CommonLocationInfo-r16 IE;

[0057] include BT-Meas-r16 IE;

[0058] include WLAN-Meas-r16 IE;

[0059] include Sensor-Meas-r16 IE.

[0060] In one embodiment, the method further comprises: when it is determined according to the instruction of the base station that the location-related information without reducing the precision needs to be reported, reporting the location-related information without reducing the precision to the base station.

[0061] In one embodiment, in addition to reporting the location-related information after reducing the precision to the base station, the terminal may also report the location-related information before reducing the precision to the base station, or may report both the location-related information after reducing the precision and the location-related information before reducing the precision. The specific information may be determined according to the instructions of the base station. For example, when the base station indicates that the location-related information without reducing the precision needs to be reported, the location-related information without reducing the precision may be reported to the base station. Among them, the indication may be carried in the event trigger configuration or the periodic report configuration, indicating that the location-related information without reducing the precision needs to be reported.

[0062] That is to say, the terminal can report the location-related information before reducing the accuracy to the base station, and can also report the location-related information after reducing the accuracy to the base station. In order for the base station to determine whether the received location-related information has been reduced in accuracy, after reporting the location-related information, the terminal can also indicate whether the reported location-related information has been reduced in accuracy.

[0063] Among them, the base station can also determine whether the terminal has agreed to user consent for reporting the location information without reducing the accuracy based on the terminal's contract information. If the terminal agrees to report the location information without reducing the accuracy, the base station will instruct the terminal to report the location-related information without reducing the accuracy as needed. If the terminal does not agree to report the location information without reducing the accuracy, the base station will not instruct the terminal to report the location-related information without reducing the accuracy.

[0064] How to reduce the accuracy of location-related information is exemplified below through several embodiments. In one embodiment, the manner of reducing the accuracy of the location-related information of the terminal includes at least one of the following:

[0065] Setting the value of the preset bit in the position-related information to a specified value;

[0066] Setting the value of a preset bit in the position-related information to a random value;

[0067] Add, subtract, multiply or divide the value of the preset bit in the position-related information by a random value;

[0068] The value of the preset bit in the position-related information is ignored.

[0069] It should be noted that the preset bits may be one or more bits in the location-related information, and may be continuous bits or discontinuous bits. The following mainly describes the present disclosure in an exemplary manner when the preset bits are the lowest bits of the location-related information. For example, the preset bits are the lowest two bits of the location-related information.

[0070] In one embodiment, the precision can be reduced by setting the value of the preset position in the location-related information to a specified value, such as zero. For example, if the location-related information is location coordinate information, which is expressed by longitude and latitude, and the longitude and latitude are accurate to two decimal places, then the two decimal places can be set to zero to reduce the precision of the location-related information; for example, if the location-related information is TA, which is expressed by millisecond-level time, and the time is accurate to two decimal places, then the two decimal places can be set to zero to reduce the precision of the location-related information.

[0071] In one embodiment, the precision can be reduced by setting the value of the preset position in the location-related information to a random value. For example, if the location-related information is location coordinate information, which is expressed by longitude and latitude, and the longitude and latitude are accurate to two decimal places, then the two decimal places can be set to a random value to reduce the precision of the location-related information; for example, if the location-related information is TA, which is expressed by millisecond-level time, and the time is accurate to two decimal places, then the two decimal places can be set to a random value to reduce the precision of the location-related information.

[0072] In one embodiment, the precision can be reduced by adding, subtracting, multiplying, or dividing the value of the preset position in the location-related information by a random value. For example, if the location-related information is location coordinate information, which is expressed by longitude and latitude, and the longitude and latitude are accurate to two decimal places, then the precision of the location-related information can be reduced by adding a random value to the two decimal places; for example, if the location-related information is TA, which is expressed by millisecond-level time, and the time is accurate to two decimal places, then the precision of the location-related information can be reduced by subtracting a random value from the two decimal places.

[0073] In one embodiment, the accuracy can be reduced by ignoring the value of the preset position in the location-related information. For example, if the location-related information is the location coordinate information, which is expressed by longitude and latitude, and the longitude and latitude are accurate to two decimal places, then the last two digits are ignored (that is, only the integer value is retained) to reduce the accuracy of the location-related information; for example, if the location-related information is TA, which is expressed by millisecond time, and the time is accurate to two decimal places, then the last two digits are ignored (that is, only the integer value is retained) to reduce the accuracy of the location-related information.

[0074] It should be noted that when the location-related information is TA, since the order of magnitude of TA is generally very small, such as at the millisecond level, if the adjustment precision is large, it may seriously affect the accuracy of TA. Therefore, for TA, the main method of reducing precision with a smaller amplitude can be used, such as adding or subtracting a random value to the value of the preset position in the location-related information.

[0075] In one embodiment, when the location related information is location coordinate information, the location related information with reduced precision is carried in an information element IE and sent to the base station, and the information element includes at least one of the following:

[0076] Location coordinate information element locationCoordinate IE;

[0077] Bluetooth log measurement result table information element LogMeasResultListBT IE;

[0078] Wireless LAN log measurement result table information element LogMeasResultWLAN IE;

[0079] Sensor location information information element Sensor-LocationInfo IE.

[0080] Figure 2 FIG. 1 is a schematic flow chart of another method for reporting location-related information according to an embodiment of the present disclosure. Figure 2 As shown, when the information element is the location coordinate information element, the step of reducing the accuracy of the location-related information of the terminal includes:

[0081] In step S201, the accuracy of the location-related information is reduced by adjusting the uncertainty field in the location coordinate information element.

[0082] In the locationCoordinate IE, the uncertainty field may represent an elliptical range, within which the location-related information is located, but is not specifically determined. The smaller the range, the higher the accuracy of the location-related information, and the larger the range, the lower the accuracy of the location-related information.

[0083] Therefore, the above range can be changed by adjusting the uncertainty field, thereby adjusting the accuracy of location-related information.

[0084] The uncertainty field may also be set to a special value agreed upon with the base station, so that after the locationCoordinate IE is reported, the base station can determine that the accuracy of the location-related information has been adjusted based on the uncertainty field being a special value.

[0085] Figure 3 FIG. 1 is a schematic flow chart of another method for reporting location-related information according to an embodiment of the present disclosure. Figure 3 As shown, the information element includes a Bluetooth log measurement result table information element and / or a wireless local area network log measurement result table information element, and the step of reducing the accuracy of the location-related information of the terminal includes:

[0086] In step S301, the accuracy of the location-related information is reduced by adjusting the received signal strength indication field in the Bluetooth log measurement result table information element and / or the wireless local area network log measurement result table information element.

[0087] In the LogMeasResultListBT IE or the LogMeasResultWLAN IE, the location-related information may be determined according to a received signal strength indication RSSI (Received Signal Strength Indication) field. Therefore, the accuracy of the location-related information may be reduced by adjusting the RSSI field.

[0088] Among them, the unit of the RSSI field can be dB. Therefore, for the adjustment of the RSSI field, in addition to adding or subtracting a random value from the value of the preset bit in the location-related information, you can also multiply or divide the value of the preset bit in the location-related information by a random value.

[0089] Figure 4 FIG. 1 is a schematic flow chart of another method for reporting location-related information according to an embodiment of the present disclosure. Figure 4 As shown, when the information element is the sensor location information information element, the step of reducing the accuracy of the location-related information of the terminal includes:

[0090] In step S401, the accuracy of the location-related information is reduced by adjusting the atmospheric pressure field in the sensor location information information element.

[0091] In the Sensor-LocationInfo IE, the location-related information can be determined based on the atmospheric pressure field, for example, it can be used to determine the location-related information in the direction perpendicular to the horizontal plane in the location-related information. Therefore, the accuracy of the location-related information can be reduced by adjusting the atmospheric pressure field.

[0092] Figure 5 FIG. 1 is a schematic flow chart of another method for reporting location-related information according to an embodiment of the present disclosure. Figure 5 As shown, the method also includes:

[0093] In step S501, the purpose of reporting location-related information is indicated, wherein the purpose includes at least one of the following: timing advance reporting TA report, minimization of drive tests MDT, and self-organizing network SON.

[0094] In one embodiment, after reporting the location-related information with reduced precision, the terminal may also indicate the purpose of reporting the location-related information, so that the base station determines the purpose of the terminal reporting the location-related information, so as to perform appropriate operations according to the location-related information with reduced precision reported by the terminal.

[0095] Figure 6 FIG. 1 is a schematic flow chart of another method for reporting location-related information according to an embodiment of the present disclosure. Figure 6 As shown, the step of reducing the accuracy of the location-related information of the terminal includes:

[0096] In step S601, the accuracy of the location-related information is reduced according to the accuracy reduction requirement indicated by the base station.

[0097] In one embodiment, the base station can indicate the accuracy reduction requirement to the terminal, indicating to what extent the accuracy needs to be reduced. For example, the accuracy can be reduced to 2 kilometers. The terminal can then reduce the accuracy of location-related information based on the accuracy reduction requirement to ensure that the reported location-related information after the reduced accuracy can meet the needs of the base station.

[0098] In one embodiment, reporting the location-related information with reduced accuracy to the base station includes:

[0099] When the triggering condition is met, the location-related information with reduced accuracy is reported.

[0100] Among them, the trigger condition can be agreed upon by the protocol, or agreed upon by the base station and the terminal, or configured by the base station to the terminal. When reporting location-related information, the terminal can first determine whether the trigger condition is met, and only report the location-related information when the trigger condition is met.

[0101] For example, in the case of base station configuration, the base station can carry the trigger condition in the trigger event configuration EventTriggerConfig of the NR (New Radio) report configuration ReportConfigNR IE.

[0102] In one embodiment, when the location-related information is location coordinate information, the trigger condition includes a location offset threshold;

[0103] When the distance between the current position coordinate information and the position at which the position-related information was previously reported is greater than the position offset threshold offset, it is determined that the trigger condition is met.

[0104] When the terminal needs to report location-related information with reduced precision, it can first determine the terminal's position when the location-related information was last reported, such as P0, and the terminal's current position, such as P1, and then calculate the distance P01 between P0 and P1. When P01 is greater than offset, it can be determined that the trigger condition is met, and then the location-related information with reduced precision is reported.

[0105] It should be noted that the last reported location information may refer to the last reported location information without reducing the accuracy. Of course, it can also be set as needed, such as the last reported location information with reduced accuracy or the last reported location information with unreduced accuracy.

[0106] In one embodiment, when the location-related information is location coordinate information, the trigger condition includes a location offset threshold offset and a hysteresis threshold Hysteresis;

[0107] Wherein, when the difference between the distance between the current position and the position when the position-related information was last reported and the hysteresis threshold is greater than the position offset threshold, it is determined that the trigger condition is met; when the sum of the distance between the current position and the position when the position-related information was last reported and the hysteresis threshold is less than the position offset threshold, it is determined that the trigger condition is not met; or

[0108] When the sum of the distance between the current position and the position when the position-related information was previously reported and the hysteresis threshold is less than the position offset threshold, it is determined that the trigger condition is met; when the difference between the distance between the current position and the position when the position-related information was previously reported and the hysteresis threshold is greater than the position offset threshold, it is determined that the trigger condition is not met.

[0109] When the terminal needs to report location-related information with reduced accuracy, it can first determine the location of the terminal when the location-related information was last reported, such as P0, and the current location of the terminal, such as P1, and then calculate the distance P01 between P0 and P1, and then determine whether the trigger condition is met based on the relationship between P01 and Hysteresis and offset.

[0110] For example, it can be set that the condition of P01 - Hysteresis > offset satisfies the trigger condition;

[0111] And it can be set that the condition of P01 + Hysteresis < offset does not satisfy the trigger condition.

[0112] Or it can be set that the condition of P01 + Hysteresis < offset satisfies the trigger condition;

[0113] And it can be set that the condition of P01 - Hysteresis > offset does not satisfy the trigger condition.

[0114] Then, when the terminal determines that the trigger condition is satisfied, it can trigger the reporting of the location - related information after reducing the accuracy; while when it determines that the trigger condition is not satisfied, it does not need to report the location - related information after reducing the accuracy. If the terminal is currently reporting (such as periodic reporting) the location - related information after reducing the accuracy, it can stop reporting the location - related information after reducing the accuracy.

[0115] In one embodiment, for the trigger condition, an effective time can also be set. Then, when the terminal determines that the trigger condition is satisfied and is currently within the effective time, it triggers the reporting of the location - related information after reducing the accuracy, while if it is not currently within the effective time, it does not need to trigger the reporting of the location - related information after reducing the accuracy.

[0116] In one embodiment, when the location - related information is TA, there are mainly two ways for the terminal to report TA. One is the TA report method (the reported content can be TA or location coordinate information), and in this method, the medium - side carries TA for reporting through the control element (MAC CE) of the control layer; the other is the method of reporting the user equipment location (UE location) (the reported content can be TA or location coordinate information), and in this method, the TA is carried for reporting through the radio resource control (RRC) signaling. The following mainly gives an exemplary description of these two cases.

[0117] Figure 7 is a schematic flowchart of another method for reporting location - related information shown according to an embodiment of the present disclosure. As Figure 7 shown, when the location - related information is the timing advance TA, the method further includes:

[0118] In step S701, when it is determined according to the indication of the base station to report the timing advance by the timing - advance reporting method, determine whether the trigger condition is satisfied according to the change amount between the current timing advance and the timing advance at the time of the most recent reporting of location - related information.

[0119] In one embodiment, the base station can instruct the terminal to report TA in a certain manner, for example, the reporting manner is TA reporting. The terminal can determine the timing advance when the most recent location-related information was reported, for example, called TA0, and the current timing advance, for example, called TA1, and then calculate the change TA01 between TA0 and TA1, and determine whether the trigger condition is met based on TA01.

[0120] For example, if TA01 is greater than the TA threshold, it is determined that the trigger condition is met, and the location-related information with reduced accuracy is reported; for example, if TA01 is less than the TA threshold, it is determined that the trigger condition is not met, and the location-related information with reduced accuracy is not reported.

[0121] The most recent location-related information reported may be the TA or the location coordinate information.

[0122] In one embodiment, determining whether the trigger condition is met according to a change between the current timing advance TA and the timing advance TA when the most recent location related information is reported includes:

[0123] It is determined whether the trigger condition is met according to a change between the current timing advance and the timing advance when the most recent location-related information is reported and the reported content is the timing advance.

[0124] That is, the terminal may be set to determine the timing advance when the most recent location-related information is reported, specifically, the TA when the most recent location-related information is reported and the content reported is the TA.

[0125] Figure 8 FIG. 1 is a schematic flow chart of another method for reporting location-related information according to an embodiment of the present disclosure. Figure 8 As shown, the reported location-related information after reducing the precision includes:

[0126] In step S801, when it is determined according to the instruction of the base station to report the location-related information in other ways, when reporting the TA in the TA reporting way has been triggered, the reporting of the TA in the TA reporting way is cancelled.

[0127] In one embodiment, when the base station instructs the terminal to report the TA through the TA reporting method, it may also instruct the terminal to report the location-related information through other methods. For example, if the purpose of reporting the location-related information is MDT or SON, then the other method refers to reporting the location-related information in the MDT or SON process.

[0128] In this case, the terminal needs to report TA in the manner in which TA is reported, and also needs to report location-related information in other ways. However, the effects of TA and location-related information on the network side are generally similar, so under normal circumstances, there is no need to report TA in the manner in which TA is reported, and also report location-related information in other ways.

[0129] Therefore, in this embodiment, when the TA reporting method is triggered, the TA reporting method can be canceled. For example, when the MAC CE carrying the TA has not been delivered to the lower layer, or has not been put into the MAC PDU (Protocol Data Unit), the cancellation action can be performed. Accordingly, repeated uploading of information with similar functions can be avoided, which is conducive to saving communication resources.

[0130] Fig. 9 FIG. 1 is a schematic flow chart of another method for reporting location-related information according to an embodiment of the present disclosure. Fig. 9 As shown, when the location-related information is a timing advance TA, the method further includes:

[0131] In step S901, when determining to report the timing advance by reporting the user equipment position according to the instruction of the base station, whether the trigger condition is met is determined according to the change between the current position and the position of the terminal when the position-related information was last reported.

[0132] In one embodiment, the base station can instruct the terminal to report TA in a certain manner, for example, the reporting manner is TA reporting. The terminal can determine the location of the terminal when the last location-related information was reported, such as L0, and the current fixed location, such as L1, and then calculate the change L01 between L0 and L1, and determine whether the trigger condition is met based on L01.

[0133] For example, if L01 is greater than the TA threshold, it is determined that the trigger condition is met, and the location-related information with reduced accuracy is reported; for example, if L01 is less than the TA threshold, it is determined that the trigger condition is not met, and the location-related information with reduced accuracy is not reported.

[0134] The most recent location-related information reported may be the TA or the location coordinate information.

[0135] In one embodiment, determining whether the trigger condition is met according to a change between the current position and the position of the terminal when the position related information was last reported includes:

[0136] Whether the trigger condition is met is determined according to a change in the position of the terminal between the current position and the last time the position-related information is reported and the reported content is position coordinate information.

[0137] That is, the terminal may be configured to determine the location of the terminal when the most recent location-related information was reported, specifically, the location of the terminal when the most recent location-related information was reported and the reported content was the location coordinates.

[0138] Fig.10 FIG. 1 is a schematic flow chart of another method for reporting location-related information according to an embodiment of the present disclosure. Fig.10 As shown, the reported location-related information after reducing the precision includes:

[0139] In step S1001, in a case where location-related information is reported by other means according to the instruction of the base station, in a case where reporting TA by reporting the location of the user equipment has been triggered, reporting TA by reporting the location of the user equipment is canceled, or TA is reported by reporting the location of the user equipment and location-related information is reported by other means.

[0140] In one embodiment, when the base station instructs the terminal to report the TA by means of UE location reporting, it may also instruct the terminal to report the location related information by other means. For example, if the purpose of reporting the location related information is MDT or SON, then the other means refers to reporting the location related information by means of reporting the location related information during the MDT or SON process.

[0141] In this case, the terminal needs to report TA through UE location reporting and report location-related information through other methods. However, the effects of TA and location-related information on the network side are generally similar, so under normal circumstances, there is no need to report TA through UE location reporting and report location-related information through other methods.

[0142] Therefore, in this embodiment, when the reporting of location-related information through other methods has been triggered and the reporting of TA through UE location reporting is triggered, you can try to cancel the reporting of TA through UE location reporting. Accordingly, you can avoid repeatedly uploading information with similar functions, which is beneficial to saving communication resources.

[0143] However, since TA is reported by UE location reporting, TA is carried in RRC signaling and the cancellation action may fail. Therefore, location related information may be reported by other methods and TA may be reported by UE location reporting.

[0144] In the case where the terminal reports both location-related information through other means and TA through UE location reporting, the location-related information reported through other means may also be TA, which may cause the base station to receive two TAs, making it difficult to distinguish the roles of the two TAs. Therefore, in this case, the terminal can indicate the purpose of reporting TA through UE location reporting and the purpose of location-related information reported through other means, such as TA report, UE location, MDT, SON, etc., so that the base station can perform appropriate processing on the two received information. In addition, it can also indicate which reported information has its precision reduced and which has not been reduced.

[0145] Fig.11 FIG. 1 is a schematic flow chart of another method for reporting location-related information according to an embodiment of the present disclosure. Fig.11 As shown, the method also includes:

[0146] In step S1101, when handover to a target base station is required, the location-related information is sent to the target base station.

[0147] In one embodiment, when the terminal determines that it needs to switch base stations, it can determine the target base station to switch to, and then report the location-related information to the target base station so that the target base station can determine the location-related information of the terminal in time.

[0148] In an embodiment, sending the location-related information to the target base station includes: sending the location-related information to the target base station during a handover to the target base station.

[0149] The terminal may send location-related information to the target base station during the switching process, for example, by sending a connection reconfiguration completion message carrying location-related information to the target base station so that the target base station can determine the location-related information of the terminal as soon as possible.

[0150] In one embodiment, sending the location-related information to the target base station includes: when it is determined that the location-related information needs to be reported based on the reconfiguration message sent by the target base station, sending the location-related information to the target base station during and / or after switching to the target base station.

[0151] The terminal can first determine whether it is necessary to report location-related information based on the reconfiguration message sent by the target base station. If it is determined that the location-related information needs to be reported, the location-related information can be sent to the target base station during the process of switching to the target base station, for example, by sending the location-related information to the target base station through a connection reconfiguration completion message, or by sending the location-related information to the target base station after switching to the target base station, for example, by triggering measurement reporting and carrying the location-related information in a measurement report and sending it to the target base station.

[0152] If it is determined that the location-related information does not need to be reported, the location-related information does not need to be sent to the target base station. Accordingly, unnecessary location-related information reporting can be avoided, which is beneficial to avoiding waste of communication resources.

[0153] It should be noted that the location-related information reported to the target base station may be location-related information with reduced accuracy or location-related information without reduced accuracy, and the specific configuration may be made as required.

[0154] In one embodiment, whether to obtain location-related information with reduced accuracy and report it when available location-related information is not stored is determined based on at least one of the following:

[0155] an indication of the base station;

[0156] Reporting a triggering event of the location-related information;

[0157] The purpose of reporting the location-related information;

[0158] The state of the terminal;

[0159] The location-related information needs to be reduced to a precision.

[0160] In one embodiment, when the terminal needs to report location-related information with reduced precision, it first needs to store available location-related information, that is, available location-related information. For example, location-related information is stored in the terminal, and the location-related information has not expired. For example, the time difference between the acquisition time of the stored location-related information and the current time is less than a preset duration, then it can be determined that the terminal stores available location-related information.

[0161] However, in some cases, the terminal does not store the available location-related information. In this case, the terminal can choose not to report the location-related information with reduced precision, or can choose to obtain the location-related information and then report the obtained location-related information with reduced precision. Which of these two operations is to be performed can be determined based on the instructions of the base station, based on the triggering event for reporting the location-related information, based on the purpose of reporting the location-related information, based on the state of the terminal, or based on the precision of the location-related information.

[0162] For example, according to the instructions of the base station:

[0163] When the base station instructs the terminal to report location-related information, if the base station clearly instructs the terminal to report available location-related information, then when the terminal triggers reporting of location-related information, if the available location-related information is not stored, it is not necessary to obtain the location-related information; if the available location-related information is stored, the available location-related information is reported;

[0164] If the terminal is only instructed to report location-related information, then when the terminal triggers the reporting of location-related information, if the available location-related information is not stored, the terminal can obtain the location-related information, and then report the obtained location-related information after reducing the precision; if the available location-related information is stored, the stored available location-related information will be reported after reducing the precision.

[0165] In addition, if the base station does not instruct to report available location-related information, nor does it instruct to report location-related information, then when the terminal triggers the reporting of location-related information, if the available location-related information is not stored, it is not necessary to obtain the location-related information; if the available location-related information is stored, the available location-related information is reported.

[0166] For example, it is determined according to the triggering event of reporting the location-related information:

[0167] The base station can configure a trigger event for the terminal to report location-related information. When the terminal reports the trigger location-related information, it can first determine whether the trigger event is met. If the trigger event is met, the terminal reports. If not, the terminal does not report.

[0168] When it is determined that the trigger event is met, if the terminal does not store the available location-related information, then it can be determined whether to obtain the location-related information based on the trigger event. For example, if the base station configures trigger event A, which requires the terminal to report the available location-related information, and trigger event B, which requires the terminal to report the location-related information, then when trigger event A is met, if the terminal does not store the available location-related information, it is not necessary to obtain the location-related information. If the available location-related information is stored, the available location-related information is reported; when trigger event B is met, if the available location-related information is not stored, the location-related information can be obtained, and then the obtained location-related information is reported after reducing the precision. If the available location-related information is stored, the stored available location-related information is reported after reducing the precision.

[0169] For example, it is determined according to the purpose of reporting the location related information:

[0170] The base station can configure the purpose of reporting location-related information for the terminal, such as TA report, SON, MDT, LCS (location service), etc. When the terminal triggers the reporting of location-related information, if the terminal does not store the available location-related information, it can determine whether to obtain the location-related information according to the purpose.

[0171] For example, if the base station's purpose is TA report, the terminal needs to report available location-related information, and if the purpose is MDT, the terminal needs to report available location-related information. Then, when the terminal determines that the purpose is TA report, if the terminal does not store available location-related information, it does not need to obtain location-related information. If the available location-related information is stored, the available location-related information is reported. When the terminal determines that the purpose is MDT, if the available location-related information is not stored, it can obtain location-related information, and then report the obtained location-related information after reducing the precision. If the available location-related information is stored, the stored available location-related information is reported after reducing the precision.

[0172] For example, it is determined according to the state of the terminal:

[0173] When the terminal triggers reporting of location-related information, if the terminal does not store available location-related information, it can determine whether to obtain location-related information based on its own status.

[0174] For example, when the terminal is in the initial random access state or the base station switching state, if the terminal does not store the available location-related information, it can obtain the location-related information, and then report the obtained location-related information after reducing the precision. If the available location-related information is stored, the stored available location-related information is reported after reducing the precision.

[0175] In addition, when the terminal is in a connected state, if the triggering event for reporting location-related information is that the difference between the current location-related information and the most recently reported location-related information is large, for example, greater than a preset value, if the terminal has not stored the available location-related information, it can obtain the location-related information, and then report the obtained location-related information after reducing the precision; if the available location-related information is stored, the stored available location-related information will be reported after reducing the precision.

[0176] When the terminal is in other states, if the terminal does not store the available location related information, it is not necessary to obtain the location related information. If the available location related information is stored, the available location related information is reported.

[0177] For example, according to the accuracy of the location-related information:

[0178] The base station can instruct the terminal to reduce the accuracy to which the location-related information needs to be reduced, and the terminal can also independently determine the accuracy to which the location-related information needs to be reduced. When the terminal triggers the reporting of location-related information, if the terminal does not store the available location-related information, it can determine whether to obtain the location-related information based on the accuracy to which the location-related information needs to be reduced. In this case, the base station does not need to instruct the terminal whether to report the available location-related information.

[0179] For example, when the terminal determines that it needs to report coarse accuracy (for example, accuracy is lower than the preset accuracy), if the terminal does not store the available location-related information, it can obtain the location-related information, and then report the obtained location-related information after reducing the accuracy. If the available location-related information is stored, the stored available location-related information will be reported after reducing the accuracy. For example, when the terminal determines that it needs to report high accuracy (for example, accuracy is higher than the preset accuracy), if the terminal does not store the available location-related information, it does not need to obtain the location-related information. If the available location-related information is stored, the available location-related information will be reported.

[0180] Fig.12It is a schematic flow chart of a method for receiving location-related information according to an embodiment of the present disclosure. The method for receiving location-related information shown in this embodiment can be executed by a base station, and the base station can communicate with a terminal, and the terminal includes but is not limited to a mobile phone, a tablet computer, a wearable device, a sensor, an Internet of Things device and other communication devices, and the base station includes but is not limited to a base station in a 4G, 5G, 6G and other communication systems.

[0181] like Fig.12 As shown, the method for receiving location-related information may include the following steps:

[0182] In step S1201, location-related information with reduced accuracy sent by a receiving terminal.

[0183] In one embodiment, the terminal and the base station may communicate through a terrestrial network or a non-terrestrial network. The technical solution of the present disclosure may be applicable to a scenario where the terminal and the base station communicate in a terrestrial network or a scenario where the terminal and the base station communicate in a non-terrestrial network. The following mainly illustrates the technical solution of the present disclosure in a scenario where the terminal and the base station communicate in a non-terrestrial network.

[0184] In a non-terrestrial network, a terminal can communicate with a base station via a satellite. For example, the base station transmits a signal to a satellite, and the satellite transmits a signal to the terminal. There are two main working modes of the satellite, one is a transparent transmission mode, and the other is a regeneration mode.

[0185] Since satellites move at high altitudes, their coverage is large and can even span several countries. The core networks of different countries may be different. For example, the access mobility management function AMF in the core network is different. Therefore, for terminals within the satellite coverage, it is necessary to select the appropriate core network access for the terminal based on the terminal's location. In this case, the accuracy required for the terminal's location is generally not high, and an accuracy of 2 kilometers is sufficient.

[0186] Of course, in addition to this case, the present disclosure is also applicable to other situations where the location accuracy is not required to be high, and some embodiments may even not consider the network side's requirements for location accuracy.

[0187] According to the embodiments of the present disclosure, the terminal can determine its own location-related information and reduce the accuracy of the location-related information, and then report the location-related information with reduced accuracy to the base station, which is beneficial to preventing the base station and other network-side devices from obtaining location-related information with too high accuracy, thereby causing the privacy of the terminal user to be leaked.

[0188] In one embodiment, the location-related information includes at least one of the following:

[0189] Position coordinate information, timing advance TA (Timing Advance).

[0190] The TA may be an uplink TA pre-compensated by the terminal. In a non-terrestrial network, it is difficult for the network to determine the uplink TA of the terminal, so it is difficult for the network to compensate the uplink TA. The terminal itself may pre-compensate the uplink TA.

[0191] In one embodiment, when the location related information is location coordinate information, the location related information with reduced precision is obtained in an information element IE, and the information element includes at least one of the following:

[0192] Location coordinate information element locationCoordinate IE;

[0193] Bluetooth log measurement result table information element LogMeasResultListBT IE;

[0194] Wireless LAN log measurement result table information element LogMeasResultWLAN IE;

[0195] Sensor location information information element Sensor-LocationInfo IE.

[0196] Fig.13 FIG. 1 is a schematic flow chart of another method for receiving location-related information according to an embodiment of the present disclosure. Fig.13 As shown, the method also includes:

[0197] In step S1301, the purpose of the terminal reporting location-related information is determined according to an instruction of the terminal, wherein the purpose includes at least one of the following: timing advance reporting TA report, minimization of drive tests MDT, and self-organizing network SON.

[0198] In one embodiment, after reporting the location-related information with reduced precision, the terminal may also indicate the purpose of reporting the location-related information, so that the base station determines the purpose of the terminal reporting the location-related information, so as to perform appropriate operations according to the location-related information with reduced precision reported by the terminal.

[0199] Fig.14 FIG. 1 is a schematic flow chart of another method for receiving location-related information according to an embodiment of the present disclosure. Fig.14 As shown, the method also includes:

[0200] In step S1401, a precision reduction request is sent to the terminal.

[0201] In one embodiment, the base station can indicate the accuracy reduction requirement to the terminal, indicating to what extent the accuracy needs to be reduced. For example, the accuracy can be reduced to 2 kilometers. The terminal can then reduce the accuracy of location-related information based on the accuracy reduction requirement to ensure that the reported location-related information after the reduced accuracy can meet the needs of the base station.

[0202] Fig.15 FIG. 1 is a schematic flow chart of another method for receiving location-related information according to an embodiment of the present disclosure. Fig.15 As shown, the method also includes:

[0203] In step S1501, the location-related information without reducing the accuracy sent by the terminal is received.

[0204] In one embodiment, in addition to reporting the location-related information after reducing the precision to the base station, the terminal may also report the location-related information before reducing the precision to the base station, or may report both the location-related information after reducing the precision and the location-related information before reducing the precision. The specific information may be determined according to the instructions of the base station. For example, when the base station indicates that the location-related information without reducing the precision needs to be reported, the location-related information without reducing the precision may be reported to the base station. Among them, the indication may be carried in the event trigger configuration or the periodic report configuration, indicating that the location-related information without reducing the precision needs to be reported.

[0205] That is to say, the terminal can report to the base station both the location-related information before reducing the accuracy and the location-related information after reducing the accuracy. Therefore, after reporting the location-related information, the terminal can also indicate whether the reported location-related information has been reduced in accuracy, so that the base station can determine whether the received location-related information has been reduced in accuracy.

[0206] Among them, the base station can also determine whether the terminal has agreed to user consent for reporting the location information without reducing the accuracy based on the terminal's contract information. If the terminal agrees to report the location information without reducing the accuracy, the base station will instruct the terminal to report the location-related information without reducing the accuracy as needed. If the terminal does not agree to report the location information without reducing the accuracy, the base station will not instruct the terminal to report the location-related information without reducing the accuracy.

[0207] Fig.16 FIG. 1 is a schematic flow chart of another method for receiving location-related information according to an embodiment of the present disclosure. Fig.16 As shown, the method also includes:

[0208] In step S1601, when the terminal needs to switch to a target base station, the location-related information is sent to the target base station.

[0209] In one embodiment, when the terminal determines that it needs to switch base stations, it can determine the target base station to be switched to, and then send the location-related information to the target base station, for example, through an interface between base stations, or through a core network, so that the target base station can determine the location-related information of the terminal in a timely manner. In addition, it can also indicate whether the location-related information sent to the target base station has reduced accuracy or has not reduced accuracy.

[0210] Corresponding to the aforementioned embodiments of the method for reporting location-related information and the method for receiving location-related information, the present disclosure also provides embodiments of a device for reporting location-related information and a device for receiving location-related information.
