[0104] The embodiments of the present disclosure will be further described below in conjunction with the accompanying drawings and specific implementation manners.

[0105] Here, the exemplary embodiments will be described in detail, and their examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the embodiments of 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.

[0106] The network - side needs to obtain the positioning capabilities of the user equipment (UE), so that the network - side can determine the positioning technology and use the determined positioning technology to locate the UE. The positioning capabilities of the UE include the identifier of the positioning technology supported by the UE, or, simultaneously include the identifier of the positioning technology supported by the UE and the positioning performance parameters of each positioning technology.

[0107] The methods for the network - side to obtain the positioning capabilities of the UE include the following two:

[0108] Method 1: The network sends a positioning capability request message to the UE, which indicates that there are multiple specified positioning technologies. After receiving the positioning capability request message, the UE checks whether it supports the above-mentioned specified positioning technologies, determines the specified positioning technologies it can support, and sends a response message to the network. This response message only contains the positioning technologies that the UE can support.

[0109] Method 2: The UE actively reports its positioning capability to the network.

[0110] At present, when NR locates UE, method 1 is used for positioning, that is, each time the UE is located, the UE needs to report its positioning capability. When the UE uses the same positioning technology for a long time, the UE frequently reports the same positioning capability, which will increase the positioning delay and cause a waste of wireless transmission resources.

[0111] In NR R17, in order to reduce positioning delay, the UE may not be required to use the above method 1 to report its positioning capability in each positioning process. Instead, after the UE reports the positioning capability once, the network side stores the positioning capability of the UE, and uses the stored positioning capability to locate the UE in the subsequent set time period or the set number of positioning times. When the network side uses the stored UE positioning capability, if the environment in which the UE is located changes, some positioning capabilities of the UE may no longer be applicable to the current environment of the UE, and the network side cannot promptly obtain the real-time positioning capability of the UE. The network side may use positioning technology that is not applicable to the environment in which the UE is located, causing the network side to fail to locate the UE, affecting the service quality of the UE.

[0112] For example, the UE can support two positioning technologies, namely Assisted GPS (A-GPS) positioning technology and Down Link-Time difference of Arrival (DL-TDOA) positioning technology. A-GPS positioning technology completes positioning based on GPS signals, and DL-TDOA positioning technology completes positioning based on Positioning Reference Signals (GPS).

[0113] At a certain moment, because the PRS signal quality and GPS signal quality of the UE's environment are both very good, the UE determines that the positioning capabilities in the current environment include DL-TDOA and A-GPS, and the positioning capabilities reported by the UE include DL-TDOA and A-GPS. The network side stores the positioning capabilities of this UE and records that the positioning technologies included in the positioning capabilities of this UE are DL-TDOA and A-GPS.

[0114] After a period of time, the UE moves to a new location where the GPS signal quality is poor and the PRS signal quality is good in the environment it is in. If the network uses A-GPS to locate the UE based on the stored UE positioning capabilities at this time, it is very likely to cause the positioning to fail.

[0115] Alternatively, at a certain moment, the network requests the positioning capabilities of the UE. The UE supports DL-TDOA and A-GPS as the positioning technologies, so the reported positioning capabilities of the UE include DL-TDOA and A-GPS. In fact, the GPS signal quality is poor and the PRS signal quality is good in the environment where the UE is at this time. If the network only selects the A-GPS positioning technology based on the positioning technologies supported by the UE reported by the UE, it is very likely to cause the positioning to fail or the positioning accuracy not to meet the requirements.

[0116] Embodiments of the present disclosure provide a positioning method, which is applied to the UE. Refer to Figure 1 , Figure 1 is a flowchart of a positioning method shown according to an exemplary embodiment. As Figure 1 shown, this method includes:

[0117] Step S11, sending information for indicating positioning-related parameters of the user equipment, where the positioning-related parameters of the user equipment are used to enable the network-side device to determine positioning parameters for positioning the user equipment.

[0118] In an embodiment, the network-side device is a core network device and / or a base station. In one embodiment, the core network device is a Location Management Function (LMF), or an Access and Mobility Management Function (AMF). In one embodiment, the base station can be a base station device based on any generation of communication technology.

[0119] The positioning capabilities include the identification of the positioning technologies supported by the UE, or simultaneously include the identification of the positioning technologies supported by the UE and the positioning performance parameters of each positioning technology. For example: when the positioning technology is DL-TDOA, its positioning performance parameters include at least one of the following fields: DL-TDOA mode, measurement capability, QCL processing capability, etc.

[0120] In an embodiment, the positioning-related parameters of the user equipment are positioning capability assistance information.

[0121] In this embodiment, in addition to reporting the positioning capability, the user equipment also reports information for indicating positioning-related parameters of the user equipment, and uses the positioning-related parameters to characterize the availability of the positioning technology supported by the user equipment, so that the network-side device can determine the optimal positioning technology and positioning parameters for the user equipment in the current network environment according to the real-time positioning-related parameters of the user equipment, improving the positioning accuracy and effectiveness, and overcoming the problem in the related technology that when the user equipment fails to report the positioning capability in time, the network-side device uses a positioning technology that the user equipment does not currently support for positioning, resulting in positioning failure.

[0122] An embodiment of the present disclosure provides a positioning method applied to a UE. This method includes Figure 1 the method shown, and: the positioning-related parameters of the user equipment at least include: positioning signal quality indication information. The positioning signal quality indication information is used to indicate at least one positioning signal quality corresponding to at least one positioning technology supported by the user equipment; wherein, the user equipment supports at least one positioning technology.

[0123] That is, in this embodiment, the positioning signal quality corresponding to the positioning technology supported by the UE is reported, thereby providing reliable reference information for the network-side device to determine the positioning technology used by the UE.

[0124] In one implementation, the positioning technologies supported by the UE can include many types, such as: GPS positioning, positioning based on positioning reference signals, WiFi-based positioning, and so on. For the sake of illustration, in the embodiments of the present disclosure, the case where the UE supports two positioning technologies, namely GPS positioning and positioning based on positioning reference signals, is taken as an example for illustration. That is: the positioning technologies indicated by the UE include at least one of the following two categories:

[0125] The first category is satellite-based positioning technologies.

[0126] For example: the first type of positioning method is the Global Positioning System (GPS) positioning method, the Assisted GPS (A-GPS) positioning method, the Global Navigation Satellite System (GNSS) positioning method, etc.

[0127] The second category is positioning technologies based on positioning reference signals.

[0128] For example, the second type of positioning method includes: Down Link-Time difference of Arrival (DL-TDOA) positioning method, Up Link-Time difference of Arrival (UL-TDOA) positioning method, Down Link Angle of Departure (DL-AoD) positioning method, Up Link Angle of Arrival (UL-AoA) positioning method, Enhanced Cell-1D (E-CID) positioning method, etc.

[0129] For the first type of positioning technology: The positioning signal quality indication information corresponding to the satellite-based positioning technology may include: Carrier to Noise Ratio of the satellite signal and / or the number of signal sources measurable by the user equipment (i.e., the number of satellites measurable by the UE).

[0130] For the second type of positioning technology: The positioning signal quality indication information corresponding to the positioning reference signal-based positioning technology may include: Reference Signal Receiving Power (RSRP) and / or Reference Signal Receiving Quality (RSRQ). Among them, the positioning signal quality characterization parameter may be the measurement result of the UE for one base station or the set of measurement results of the UE for multiple base stations.

[0131] In an embodiment, the information of the positioning-related parameters includes:

[0132] The positioning signal quality indication information corresponding to the satellite-based positioning technology, and the positioning signal quality indication information corresponding to the satellite-based positioning technology includes: Carrier to Noise Ratio of the satellite signal and / or the number of satellites measurable by the user equipment;

[0133] And / or, the positioning signal quality indication information corresponding to the positioning reference signal-based positioning technology, including: Reference Signal Receiving Power and / or Reference Signal Receiving Quality.

[0134] For example, the positioning technologies supported by the user equipment include: A-GNSS (Assisted-GNSS) and DL-TDOA. A-GNSS belongs to the first type of positioning technology, and the positioning signal quality characterization parameters include: the carrier-to-noise ratio of the satellite signal (Carrier to Noise Ratio) and / or the number of signal sources measurable by the user equipment (e.g., the number of satellites measurable by the UE). DL-TDOA belongs to the second type of positioning technology, and the positioning signal quality characterization parameters include: RSRP and / or RSRQ.

[0135] Selection conditions are set in the network-side device to select a positioning technology and positioning parameters according to at least one positioning signal quality characterization parameter.

[0136] In this embodiment, when the UE reports its positioning capabilities, it also reports the positioning-related parameters of the user equipment. These positioning-related parameters include the positioning signal quality characterization parameters corresponding to the positioning technologies supported by the UE, enabling the network side to not only know the positioning technologies supported by the UE but also the quality of the positioning signals of each positioning technology used by the UE in the current environment. Thus, by comprehensively considering the quality of the positioning signals of each positioning technology, the network side can select the positioning technology with the best positioning quality in the current environment from the positioning technologies supported by the UE, ensuring the smooth completion of positioning and improving the positioning success rate.

[0137] Embodiments of the present disclosure provide a positioning method applied to a UE. This method includes Figure 1 the method shown, and: the positioning-related parameters of the UE include: the recommended positioning technology; wherein, the recommended positioning technology is the positioning technology recommended for use by the user equipment. In a possible embodiment of the present disclosure, the recommended positioning technology may be the positioning technology recommended for use by the network-side device. The recommended positioning technology is one or more of the positioning technologies supported by the UE. That is: the UE can recommend one positioning technology, and the UE can also recommend two or more positioning technologies. In some embodiments, when the UE recommends two or more positioning technologies, it may also include parameters related to the priority of the recommended positioning technologies.

[0138] In one implementation manner, the recommended positioning technology is one or more of the positioning technologies with the best positioning signal quality of the UE in the current environment. For example: the UE obtains the positioning signal quality of each positioning technology in real time and selects the positioning technology with the best positioning signal quality as the recommended positioning technology. Another example: the UE obtains the positioning signal quality of each positioning technology in real time and selects several positioning technologies with the best positioning signal quality as the recommended positioning technologies.

[0139] When the network - side device determines a positioning technology to locate the UE based on positioning - related parameters, it preferentially adopts the recommended positioning technology. Or, after comprehensively evaluating according to the relevant parameters and the recommended positioning technology, it determines a positioning technology. Among them, the relevant parameters can be, for example: the positioning capability of the UE, or environmental parameters, or parameters related to the comprehensive scheduling of multiple UEs in the system, and so on.

[0140] That is, in this embodiment, the recommended positioning technology of the UE is reported, thus providing reliable reference information for the network - side device to determine the positioning technology used by the UE.

[0141] In this embodiment, by reporting the recommended positioning technology of the UE while reporting the positioning capability, the decision - making weight of the UE for the selection of the positioning technology is increased, and the network - side device can directly use the recommended positioning technology of the UE, saving the processing capacity of the network - side device.

[0142] An embodiment of the present disclosure provides a positioning method applied to a UE. This method includes Figure 1 the method shown, and: the positioning - related parameters of the UE include: the recommended positioning technology, and at least one positioning signal quality indication information corresponding to the positioning technology supported by the user equipment.

[0143] That is, in this embodiment, the recommended positioning technology of the UE is reported, and at least includes the positioning signal quality indication information corresponding to the recommended positioning technology, thus providing reliable reference information for the network - side device to determine the positioning technology used by the UE.

[0144] Of course, those skilled in the art can understand that in this embodiment, the UE can report the recommended positioning technology, the positioning signal quality indication information corresponding to the recommended positioning technology, and can also report the positioning signal quality indication information corresponding to other positioning technologies supported by the UE.

[0145] In this embodiment, combining the above two embodiments, when the UE reports its positioning capability, it also reports the positioning - related parameters of the user equipment and the recommended positioning technology of the UE. The positioning - related parameters include the positioning signal quality indication information corresponding to the positioning technology supported by the UE, enabling the network - side to not only know the positioning technology supported by the UE, but also know the quality of the positioning signals of each positioning technology used by the UE in the current environment. Thus, considering the quality of the positioning signals of each positioning technology, it selects the positioning technology with the best positioning quality in the current environment from the positioning technologies supported by the UE, or directly uses the recommended positioning technology of the UE, saving the processing capacity of the network - side device, or comprehensively considering the quality of the positioning signals of each positioning technology and the recommended positioning technology of the UE, and selecting the positioning technology with the best positioning quality in the current environment from the positioning technologies supported by the UE.

[0146] An embodiment of the present disclosure provides a positioning method applied to a UE, and this method includes Figure 1 the method shown, and: the positioning-related parameters of the user equipment at least include: at least one positioning technology supported by the user equipment and at least one corresponding positioning signal quality indication information, and a recommended positioning technology;

[0147] Wherein, the positioning signal quality indication information is used to indicate at least one positioning signal quality corresponding to at least one positioning technology supported by the user equipment, and the recommended positioning technology is the positioning technology recommended for use by the user equipment.

[0148] In this embodiment, the UE reports all the positioning technologies it supports and the positioning signal quality indication information corresponding to each positioning technology, and also reports the recommended positioning technology, so that the network side can obtain as much information as possible about the positioning situation of the UE, and thus determine the most applicable positioning parameters in the current environment where the UE is located.

[0149] An embodiment of the present disclosure provides a positioning method applied to a UE, and this method includes Figure 1 the method shown, and:

[0150] In step S11, information for indicating the positioning-related parameters of the user equipment is sent, including: sending a Long-Term Evolution (LTE) Positioning Protocol (LPP) message to a network-side device, where the LTE Positioning Protocol (LPP) message at least carries the information for indicating the positioning-related parameters of the user equipment.

[0151] In one embodiment, the information on the positioning-related parameters is sent during the LPP positioning capability transfer procedure (LPPCapability Transfer Procedure), that is, it can be sent through any appropriate signaling during the LPP positioning capability transfer procedure (LPPCapability Transfer Procedure). In another embodiment, the information on the positioning-related parameters is sent during the LPP positioning capability indication procedure (LPP Capability Indication Procedure), that is, it can be sent through any appropriate signaling during the LPP positioning capability indication procedure (LPP Capability Indication Procedure). In still other embodiments, the information on the positioning-related parameters is sent through the Provide Capabilities message during the LPP positioning capability transfer procedure (LPP Capability Transfer Procedure). In some embodiments, the information on the positioning-related parameters is sent through the Provide Capabilities message during the LPP positioning capability indication procedure (LPPCapability Indication Procedure). In one embodiment, positioning capability assistance information is carried in the Provide Capabilities message in the LPP message, and this Provide Capabilities message is the Provide Capabilities message during the LPP capability transfer procedure (LPP Capability Transfer Procedure).

[0152] As Figure 2 shown, the network-side device sends a Request Capabilities message to the UE. After receiving this Request Capabilities message, the UE responds to this Request Capabilities message and sends a Provide Capabilities message to the network-side device. The positioning capability and the information for indicating the positioning-related parameters of the user equipment are carried in the Provide Capabilities message sent to the network-side device here.

[0153] In one embodiment, the information for indicating the positioning-related parameters of the user equipment is carried in the Provide Capabilities message in the LPP message. This Provide Capabilities message is the Provide Capabilities message in the LPP Capability Indication Procedure.

[0154] As Figure 3 shown, the UE actively sends a Provide Capabilities message to the network-side device, and the positioning capabilities and the information for indicating the positioning-related parameters of the user equipment are carried in this Provide Capabilities message.

[0155] Embodiments of the present disclosure provide a positioning method applied to a UE. This method includes Figure 1 the method shown, and:

[0156] In step S11, the information for indicating the positioning-related parameters of the user equipment is sent, including: sending a user equipment assistance information message to the base station, and carrying the information for indicating the positioning-related parameters of the user equipment in the user equipment assistance information message, so that the base station forwards the user equipment assistance information message to the core network device.

[0157] In one embodiment, the user equipment assistance information message is the UE Assistance Information message fed back by the UE after receiving the RRC Reconfiguration message. Among them, RRC in the RRC Reconfiguration message refers to Radio Resource Control.

[0158] As Figure 4 shown, the information for indicating the positioning-related parameters of the user equipment is sent, including:

[0159] Step S401, the UE receives a Radio Resource Control Reconfiguration message (RRC Reconfiguration) from the base station.

[0160] Step S402: In response to receiving a Radio Resource Control Reconfiguration message (RRC Reconfiguration), the UE sends a UE Assistance Information message to the base station, carrying positioning capabilities and information indicating positioning-related parameters of the user equipment in the UE Assistance Information message.

[0161] Step S403: The base station forwards the UE Assistance Information message to the core network device through an NR Positioning Protocol A (NRPPa) message.

[0162] An embodiment of the present disclosure provides a positioning method applied to a UE. Referring to Figure 5 , Figure 5 is a flowchart of a positioning method shown according to an exemplary embodiment. This method includes:

[0163] Step S51: Receive a positioning capability request message from a network-side device.

[0164] Step S52: According to the positioning capability reporting indication in the positioning capability request message, send the positioning capability and / or the information indicating the positioning-related parameters of the user equipment to the network-side device.

[0165] In one embodiment, the positioning capability request message in Step S51 includes one of the following positioning capability reporting indications: One, a periodic reporting indication;

[0166] Two, a reporting indication triggered by a change in positioning capability;

[0167] Three, a reporting indication triggered by a positioning signal quality threshold.

[0168] In one embodiment, in Step S52, according to the positioning capability reporting indication in the positioning capability request information, sending the positioning capability and the information indicating the positioning-related parameters of the user equipment to the network-side device includes one of the following:

[0169] One, according to the periodic reporting indication, periodically report the positioning capability and the information indicating the positioning-related parameters of the user equipment;

[0170] Two, according to the reporting indication triggered by a change in positioning capability, when the positioning capability of the user equipment changes, report the positioning capability and the information indicating the positioning-related parameters of the user equipment;

[0171] Third, according to the reporting indication triggered based on the positioning signal quality threshold, when the positioning signal quality of at least one positioning technology of the user equipment is lower than or higher than the triggering threshold, report the positioning capability and information for indicating the positioning-related parameters of the user equipment.

[0172] In one embodiment, when the UE uses the above third reporting method, that is, according to the reporting indication triggered based on the positioning signal quality threshold, when the positioning signal quality of at least one positioning technology of the user equipment is lower than or higher than the triggering threshold, it also reports the information of the triggering threshold that triggers this reporting.

[0173] Typically, in step S52, the UE can simultaneously send the positioning capability and the information for indicating the positioning-related parameters of the user equipment to the network-side device.

[0174] In this embodiment, the UE obtains the positioning capability reporting indication by receiving the positioning capability request message, and reports using the corresponding reporting method according to the positioning capability reporting indication, which can improve the timeliness and effectiveness of the positioning capability reporting, overcome the problem of resource waste caused by the UE's frequent reporting in the related technology, and the problem that the network-side positioning fails because the positioning capability change cannot be reported in time when the positioning capability changes.

[0175] The embodiment of the present disclosure provides a positioning method applied to a UE. This method includes Figure 5 The method shown, and: the positioning capability request message received from the network-side device in step S51 includes a periodic reporting indication. In step S52, according to the positioning capability reporting indication in the positioning capability request message, send the positioning capability and the information for indicating the positioning-related parameters of the user equipment to the network-side device, including: the UE periodically reports the positioning capability and the information for indicating the positioning-related parameters of the user equipment.

[0176] In one embodiment, the UE reports the positioning capability and the information for indicating the positioning-related parameters of the user equipment when the reporting period arrives.

[0177] In one case, a preset reporting period value is stored in the UE.

[0178] In another case, the positioning capability request message received by the UE from the network-side device further includes the value of the reporting period. The UE obtains the specific value of the reporting period from the positioning capability request message.

[0179] The embodiment of the present disclosure provides a positioning method applied to a UE. This method includes Figure 5The method shown, and: The positioning capability request message received from the network-side device in step S51 includes a reporting indication triggered based on a change in positioning capability. In step S52, according to the positioning capability reporting indication in the positioning capability request message, send the positioning capability and the information for indicating the positioning-related parameters of the user equipment to the network-side device, including: According to the reporting indication triggered based on the change in positioning capability, when the positioning capability of the user equipment changes, report the positioning capability and the information for indicating the positioning-related parameters of the user equipment.

[0180] In one embodiment, the change in positioning capability includes at least one of the following:

[0181] One, the set of positioning technologies supported by the UE changes, that is, the positioning technologies included in the positioning set change. For example, if the original positioning set is {A-GNSS, DL-TDOA} and the positioning set is updated to {A-GNSS}, it means the positioning set has changed.

[0182] Two, the change in positioning capability includes a change in the positioning performance parameters of the positioning technologies supported by the UE.

[0183] Embodiments of the present disclosure provide a positioning method applied to a UE. This method includes Figure 5 The method shown, and: The positioning capability request message received from the network-side device in step S51 includes a reporting indication triggered based on a positioning signal quality threshold. In step S52, according to the positioning capability reporting indication in the positioning capability request message, send the positioning capability and the information for indicating the positioning-related parameters of the user equipment to the network-side device, including: According to the reporting indication triggered based on the positioning signal quality threshold, when the positioning signal quality of at least one positioning technology of the user equipment is lower than or higher than the trigger threshold, report the positioning capability and the information for indicating the positioning-related parameters of the user equipment.

[0184] In one embodiment, the values of the trigger thresholds for the positioning signal quality of each positioning technology are already stored in the UE.

[0185] In one embodiment, the positioning capability request message received by the UE from the network-side device further includes the value of the trigger threshold for the positioning signal quality. The UE obtains the value of the trigger threshold from the positioning capability request message.

[0186] In one embodiment, when the positioning signal quality of at least one positioning technology of the user equipment is lower than or higher than the trigger threshold, the UE also reports the information of the trigger threshold that triggers this reporting, so that the network-side device can conveniently know which positioning signal threshold in which positioning technology triggers the reporting.

[0187] For example: Receive a positioning capability request message from a network-side device, where the positioning capability request message includes a reporting indication triggered by a threshold of A-GNSS signal quality. When the A-GNSS signal quality is less than the A-GNSS signal quality threshold, report the positioning capability and information for indicating positioning-related parameters of the user equipment, and also report the corresponding identifier of the A-GNSS signal quality threshold.

[0188] An embodiment of the present disclosure provides a positioning method applied to a UE. This method includes Figure 5 the method shown, and: the positioning capability request message received from the network-side device in step S51 includes a reporting indication of a time point calculated based on an algorithm, and also includes information indicating a first algorithm.

[0189] The UE determines the reporting time point according to the first algorithm and reports at the reporting time point, and the time intervals between multiple adjacent reporting time points corresponding to the first algorithm are not exactly the same.

[0190] In an embodiment, the first algorithm includes one of the following:

[0191] One, within each set duration, use a set strategy to determine the interval between each set of adjacent reporting time points.

[0192] 1. The set strategy includes a set duration, a starting interval value, and an increment.

[0193] For example: The set duration is 3 seconds, and the set strategy is to calculate the moment of each reporting time point with a starting interval value of 20 ms and an increment of 1 ms. The start moment of a first set duration is t.

[0194] The first reporting time point t1 is t + 20 ms.

[0195] The second reporting time point t2 is t1 + 21 ms.

[0196] The third reporting time point t3 is t2 + 22 ms.

[0197] The fourth reporting time point t4 is t3 + 23 ms.

[0198] ...... And so on until the set duration ends. Restart the calculation of a set duration.

[0199] 2. The set strategy includes: a set duration, a starting interval value, and a decrement.

[0200] The set duration is 1 second, and the set strategy is to calculate the moment of each reporting time point with a starting interval value of 500 ms and a decrement of 1 ms. For example, the start moment of a first set duration is t.

[0201] The first reporting time point t1 is t + 500 ms.

[0202] The second reporting time point t2 is t1 + 499 ms.

[0203] The third reporting time point t3 is t2 + 498 ms.

[0204] The fourth reporting time point t4 is t3 + 497 ms.

[0205] ...... And so on until the set duration ends. Then start calculating a new set duration.

[0206] 3. The set strategy includes a set duration and a sequence of interval values. The sequence of interval values includes multiple interval values arranged in order.

[0207] The set duration is 1 second, and the sequence of interval values is 20 ms, 40 ms, 60 ms, and 80 ms. Within a set duration, the sequence of interval values is cyclically used. For example, the start time of a set duration is t.

[0208] The first reporting time point t1 is t + 20 ms.

[0209] The second reporting time point t2 is t1 + 40 ms.

[0210] The third reporting time point t3 is t2 + 60 ms.

[0211] The fourth reporting time point t4 is t3 + 80 ms.

[0212] The fifth reporting time point t5 is t4 + 20 ms.

[0213] The sixth reporting time point t6 is t5 + 40 ms.

[0214] ...... And so on until the set duration ends. Then start calculating a new set duration.

[0215] Second, use a set function to determine the interval between each pair of adjacent reporting time points. Among them, the set function is a function with the time point as the X-axis and the time interval as the Y-axis. According to a time point, a time interval can be calculated using the set function. For example: the set function is a sine deformation function, a cosine deformation function, etc.

[0216] For example: the intervals calculated by the set function are successively: D1, D2, D3, D4......, and the unit of each interval is ms.

[0217] The start time is t.

[0218] The first reporting time point t1 is t + D1.

[0219] The second reporting time point t2 is t1 + D2.

[0220] The third reporting time point t3 is t2 + D3.

[0221] The fourth reporting time point t4 is t3 + D4.

[0222] ... and so on.

[0223] The embodiment of the present disclosure provides a positioning method applied to a UE. This method includes Figure 5 the method shown, and: the positioning capability request message received from the network side device in step S51 includes a reporting indication triggered based on the degree of change in the positioning signal quality.

[0224] When the degree of change in the positioning signal quality of any positioning technology of the UE is greater than or equal to the set degree of change, the UE reports the positioning capability and information for indicating the positioning-related parameters of the user equipment.

[0225] The positioning technology is a satellite-based positioning technology, and the positioning signal quality characterization parameters include: carrier-to-noise ratio (Carrier to Noise Ratio) and / or the number of signal sources (i.e., the number of satellites measurable by the UE).

[0226] The positioning technology is a positioning reference signal-based positioning technology, and the positioning signal quality characterization parameter is the quality of the positioning reference signal. The quality of this positioning reference signal includes: reference signal receiving power (RSRP, Reference Signal Receiving Power) and / or reference signal receiving quality (RSRQ, Reference Signal Receiving Quality). Among them, the quality of the positioning reference signal can be the measurement result of a base station for a UE, or a set of measurement results of multiple base stations for the same UE.

[0227] There are various ways to represent the degree of change, such as percentage, change value, etc.

[0228] For example: when the degree of change is a percentage, the set degree is 20%. When the original parameter value is X, the degree of change is 20%, and after the parameter value is updated to Y, when the absolute value of the difference between Y and X is greater than 20% of X, it is considered that the degree of change of this parameter is greater than the set degree; when the absolute value of the difference between Y and X is equal to 20% of X, it is considered that the degree of change of this parameter is equal to the set degree; when the absolute value of the difference between Y and X is less than 20% of X, it is considered that the degree of change of this parameter is less than the set degree.

[0229] For example, when the degree of change is a change value, the set change value is Z. When the original parameter value is X and the parameter value is updated to Y, if the absolute value of the difference between Y and X is greater than Z, it is considered that the degree of change of this parameter is greater than the set degree; if the absolute value of the difference between Y and X is equal to Z, it is considered that the degree of change of this parameter is equal to the set degree; if the absolute value of the difference between Y and X is less than Z, it is considered that the degree of change of this parameter is less than the set degree.

[0230] The embodiments of the present disclosure provide a positioning method applied to a UE. This method includes Figure 5 the method shown in the figure, and: the positioning capability request message received from the network-side device in step S51 includes at least two of the following indications: periodic reporting indication, reporting indication triggered by a change in positioning capability, reporting indication triggered by a positioning signal quality threshold, reporting indication at a time point calculated based on an algorithm, and reporting indication triggered by a change in the degree of positioning signal quality.

[0231] When the UE meets the reporting conditions corresponding to any indication included in the positioning capability request message, it reports the positioning capability and information for indicating the positioning-related parameters of the user equipment.

[0232] The embodiments of the present disclosure provide a positioning method applied to a UE. This method includes Figure 5 the method shown in the figure, and: a positioning capability request message is received from the network-side device in step S51, and the positioning capability request message includes a field for indicating a reporting indication, and the reporting indication is used to represent the positioning capability reporting method.

[0233] For example:

[0234] When the value in this field is 000, it represents a periodic reporting indication;

[0235] When the value in this field is 001, it represents a reporting indication triggered by a change in positioning capability;

[0236] When the value in this field is 002, it represents a reporting indication triggered by a positioning signal quality threshold;

[0237] When the value in this field is 003, it represents a periodic reporting indication and a reporting indication triggered by a change in positioning capability;

[0238] When the value in this field is 004, it represents a periodic reporting indication and a reporting indication triggered by a positioning signal quality threshold;

[0239] When the value in this field is 005, it represents a periodic reporting indication, a reporting indication triggered by a change in positioning capability, and a reporting indication triggered by a positioning signal quality threshold.

[0240] The embodiments of the present disclosure provide a positioning method applied to a network-side device. Refer toFigure 6 , Figure 6 is a flowchart of a positioning method shown according to an exemplary embodiment. As Figure 6 shown, this method includes:

[0242] Step S62, determining positioning parameters for positioning the user equipment according to the information for indicating the positioning-related parameters of the user equipment.

[0243] In this embodiment, in addition to receiving the positioning capabilities reported by the user equipment, the network-side device also receives the information sent by the user equipment for indicating the positioning-related parameters of the user equipment, determines the availability of the positioning technologies supported by the user equipment according to this information, so that the network-side device can determine the optimal positioning technology and positioning parameters for the user equipment in the current network environment according to the real-time positioning-related parameters of the user equipment, improving the positioning accuracy and effectiveness, and overcoming the problem in the related art that when the user equipment fails to report the positioning capabilities in time, the network-side device uses a positioning technology that the user equipment does not currently support for positioning, resulting in positioning failure.

[0244] An embodiment of the present disclosure provides a positioning method, which is applied to a network-side device. This method includes Figure 6 the method shown, and: the positioning-related parameters of the user equipment in the information for indicating the positioning-related parameters of the user equipment in step S61 at least include: positioning signal quality indication information; wherein the positioning signal quality indication information is used to indicate at least one positioning signal quality corresponding to at least one positioning technology supported by the user equipment;

[0245] wherein, the user equipment supports at least one positioning technology;

[0246] In step S62, determining the positioning parameters for positioning the user equipment according to the information for indicating the positioning-related parameters of the user equipment includes: determining the positioning parameters for positioning the user equipment from the positioning technologies supported by the user equipment according to the positioning signal quality indication information.

[0247] That is, in this embodiment, the network-side device determines the positioning signal quality corresponding to the positioning technology supported by the UE, so that the positioning technology used by the UE can be determined more accurately.

[0248] In one embodiment, the positioning techniques supported by the UE may include many types, such as: GPS positioning, positioning based on positioning reference signals, WiFi-based positioning, and so on. For the sake of convenience, in the embodiments of the present disclosure, the two positioning techniques of GPS positioning and positioning based on positioning reference signals supported by the UE are taken as examples for illustration. That is, the positioning techniques indicated by the UE include at least one of the following two categories:

[0249] The first category, satellite-based positioning techniques;

[0250] The second category, positioning techniques based on positioning reference signals.

[0253] Selection conditions are set in the network-side device for selecting a positioning technique and positioning parameters according to the positioning signal quality indication information.

[0254] For example: The selection condition is: determine the positioning technique with the best signal quality according to the signal quality characterization information, and use the positioning technique with the best signal quality to position the user equipment.

[0255] For example: The selection condition is: when A-GNSS is included in the positioning capabilities and the carrier-to-noise ratio of A-GNSS is greater than or equal to the first threshold, select A-GNSS as the positioning technique; when A-GNSS is included in the positioning capabilities and the carrier-to-noise ratio of A-GNSS is less than the first threshold, select any other positioning technique in the positioning capabilities.

[0256] For example: The selection condition is: when A-GNSS is included in the positioning capabilities, the carrier-to-noise ratio of A-GNSS is greater than the first threshold, and the number of signal sources is greater than or equal to the second threshold, select A-GNSS as the positioning technique; when A-GNSS is included in the positioning capabilities and the number of signal sources of A-GNSS is less than the second threshold, select any other positioning technique in the positioning capabilities.

When the carrier-to-noise ratio of A-GNSS is less than the first threshold or the number of signal sources is less than the second threshold, any other positioning technology in the positioning capability is selected.

[0286] An embodiment of the present disclosure provides a positioning method, which is applied to a base station device. This method includes Figure 6 The method shown in the figure, and: In step S61, receive the information for indicating the positioning-related parameters of the user equipment sent by the user equipment, including: receive the UE Assistance Information message sent by the user equipment, and the information for indicating the positioning-related parameters of the user equipment is carried in the UE Assistance Information message; The method further includes: forwarding the UE Assistance Information message to the core network device. Specifically, the base station receives the UE Assistance Information message sent by the user equipment and forwards the UE Assistance Information message to the core network device.

[0287] An embodiment of the present disclosure provides a positioning method, which is applied to a network-side device. Refer to Figure 7 , Figure 7 is a flowchart of a positioning method shown according to an exemplary embodiment, as Figure 7 shown, including:

[0288] Step S71, send a positioning capability request message to the user equipment, and include a positioning capability reporting indication in the positioning capability request message.

[0289] In an embodiment, send a positioning capability request message to the user equipment, and include one of the following positioning capability reporting indications in the positioning capability request message:

[0290] Periodic reporting indication;

[0291] Reporting indication triggered based on a change in positioning capability;

[0292] Reporting indication triggered based on a positioning signal quality threshold.

[0293] In an embodiment, in step S71, send a positioning capability request message to the user equipment, and include a periodic reporting indication in the positioning capability request message.

[0294] In an example, send a positioning capability request message to the user equipment, include a periodic reporting indication in the positioning capability request message, and include the value of the reporting period.

[0295] In one example, the network-side device sets the reporting period in one of the following ways:

[0296] 1. Set the same reporting period for each UE.

[0297] 2. Set the same reporting period for UEs of the same type and different reporting periods for UEs of different types. Here, the type refers to the manufacturer, model of the UE, and the type of the supported radio communication network (such as 4G, non-standalone 5G network, standalone 5G network, etc.).

[0298] 3. Determine a real-time variable reporting period for each UE according to the historical positioning information of each UE.

[0299] For example: The value of the reporting period is negatively correlated with the change amplitude of the positioning position of the UE, that is, the larger the change amplitude of the positioning position of the UE, the smaller the value of the reporting period, and the smaller the change amplitude of the positioning position of the UE, the larger the value of the reporting period.

[0304] In one embodiment, in step S71, a positioning capability request message is sent to the user equipment, and a reporting indication triggered based on the degree of change in positioning signal quality is included in the positioning capability request message, so that when the degree of change in the positioning signal quality of any positioning technology of the UE is greater than a set degree of change, the positioning capability and information for indicating positioning-related parameters of the user equipment are reported.
