[0055] FIG1 is a block diagram of a wireless communication system applicable to an embodiment of the present application.

Wearable devices include: smart watches, smart bracelets, smart headphones, smart glasses, smart jewelry (smart bracelets, smart bracelets, smart rings, smart necklaces, smart anklets, smart anklets, etc.), smart wristbands, smart clothing, etc. Among them, the vehicle-mounted device can also be called a vehicle-mounted terminal, vehicle-mounted controller, vehicle-mounted module, vehicle-mounted component, vehicle-mounted chip or vehicle-mounted unit, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application.
[0056] A terminal may also be referred to as user equipment (UE), terminal equipment, access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device, etc.

The access network device may include a base station, a wireless local area network (WLAN) access point (AP), or a wireless fidelity (WiFi) node. Among them, the base station can be referred to as Node B (NB), Evolved Node B (eNB), the next generation Node B (gNB), New Radio Node B (NR Node B), access point, Relay Base Station (RBS), Serving Base Station (SBS), Base Transceiver Station (BTS), radio base station, radio transceiver, Basic Service Set (BSS), Extended Service Set (ESS), Home Node B (HNB), Home Evolved Node B (home evolved Node B), Transmission Reception Point (TRP) or other appropriate terms in the field. As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.
[0058] In some embodiments of the present application, the access network device may be a satellite or a balloon station. For example, the satellite may be a low earth orbit (LEO) satellite, a medium earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, a high elliptical orbit (HEO) satellite, etc. In some embodiments of the present application, the network device may also be a base station located in a location such as land or water.
[0059] To facilitate understanding of the embodiments of the present application, non-terrestrial networks related to the present application are described.
[0060] Non-terrestrial networks refer to networks or network segments that use satellite or unmanned aircraft system (UAS) platforms for transmission. Compared with terrestrial networks (TN), satellite-based non-terrestrial communication systems have a wider coverage area. Typical applicable scenarios include situations where ground base stations cannot be built or are damaged, such as continuous coverage in remote mountainous areas, deserts, oceans, and forests, and emergency communications when ground base stations are damaged due to natural disasters.
[0061] In the embodiment of the present application, the satellite may include but is not limited to LEO satellites, MEO satellites, GEO satellites, and HEO satellites.
[0062] There are two types of NTN communication systems: those based on transparent payloads and those based on regenerative payloads. In some scenarios, only the transparent payload-based NTN communication system is considered. In this deployment scenario, terminals, base stations, and core network equipment are all deployed on the ground. Communication data between terminals and network equipment is relayed via satellites in the air, as shown in Figure 2. In this communication system, satellites only forward data between base stations and terminals and do not decode or process this data. In the regenerative payload-based NTN communication system, satellites have some or all of the base station functions and can decode and process uplink or downlink data. As shown in Figure 3, the link between the satellite and the terminal is the service link, the link between the satellite and the ground gateway is the feeder link, and the link between satellites is the intersatellite link.
[0063] In the NTN communication system, the following cell deployments can be included:
[0064] Earth-moving cell: The cell (ground coverage area) moves over time;
[0065] Quasi-earth-fixed cell: A cell covers one geographic area for a period of time and a different geographic area for another period of time. For example, a satellite can achieve this by generating a steerable beam.
[0066] Earth-fixed cell: A cell that consistently covers the same geographical area, such as the cell coverage provided by geostationary satellites.
[0067] To facilitate understanding of the embodiments of the present application, the location-based measurement initiation related to the present application is described.
[0068] Due to the subtle near-far effect in the NTN communication system, a location-based cell reselection measurement criterion is introduced. The terminal can determine whether to start neighbor cell measurement based on the Reference Signal Receiving Power (RSRP) / Reference Signal Receiving Quality (RSRQ) measurement criterion and the location-based measurement criterion.
[0069] If the traditional S criterion is met (i.e., the Srxlev / Squal ratio of the serving cell is greater than a threshold), and the distance between the terminal and the reference location of the serving cell is less than a threshold, the terminal may not perform measurements on neighboring cells of the same or lower priority levels on the same or different frequencies, or on neighboring cells of different radio access technologies (RATs) with lower priority levels. The reference location and threshold of the serving cell are broadcast via system messages.
[0070] To facilitate understanding of the embodiments of the present application, the discontinuous coverage related to the present application is explained.
[0071] In the early stages of NTN deployment, satellite deployment is not very dense and coverage holes may occur. If a terminal detects a coverage hole based on satellite assistance information, the terminal does not need to perform idle state operations related to NTN.
[0072] To facilitate understanding of the embodiments of the present application, the mobility of NTN and TN (NTN-TN mobility) related to the present application is described.
[0073] Since the coverage area of the NTN cell is much larger than that of the TN cell, in the area where the NTN cell and the TN cell overlap, in order to avoid the terminal performing unnecessary TN measurements, the NTN cell can broadcast the coverage area of the TN cell. If the terminal is not in the TN coverage area, the terminal does not perform measurements on the frequency corresponding to the TN coverage area.
[0074] In a TN system, in order to enable the network side to analyze network coverage holes, the network side can configure the terminal to perform measurements and record in a non-connected state. After the terminal becomes connected, it can report the recorded information based on the instructions of the network side.
[0075] However, in the NTN system, how terminals perform measurement recording to assist the network side in analyzing network coverage vulnerabilities or optimizing network configuration is an urgent problem that needs to be solved.
[0076] The measurement recording method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.
[0077] FIG4 is a schematic diagram of a measurement recording method provided in an embodiment of the present application. As shown in FIG4 , the method 400 includes at least part of the following:
[0078] S401: A terminal obtains a first configuration, where the first configuration is used to configure a condition for the terminal to perform measurement logging.
[0079] S402: The terminal performs measurement recording according to the first configuration.
[0080] In some embodiments, the first configuration is used to configure a condition for the terminal to perform measurement logging in a non-connected state. The non-connected state may include a Radio Resource Control (RRC) idle (RRC_IDLE) state and / or an RRC inactive (RRC_INACTIVE) state.
[0081] In some embodiments, the first configuration may be obtained from a first network-side device, which may be a network-side device connected to the terminal before the terminal enters the unconnected state, that is, the first configuration is obtained when the terminal is in the connected state. For example, the first configuration may be carried in a LoggedMeasurementConfiguration message.
[0082] In the embodiment of the present application, the terminal performing measurement logging may include: the terminal recording a measurement result (eg, a signal measurement result) of at least one of a serving cell and a neighboring cell, wherein at least one of the serving cell and the neighboring cell is an NTN cell.
[0083] Optionally, the measurement result may include but is not limited to at least one of the following:
[0084] Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Received Signal Strength Indication (RSSI), Signal to Interference plus Noise Ratio (SINR).
[0085] In some embodiments, the first configuration includes at least one of the following:
[0086] information related to a first event, where the first event is related to a first distance;
[0087] first area related information, where the first area is related to at least one of a terrestrial network TN area and a geographical area;
[0088] Information related to a second event, where the second event is related to the terminal detecting that coverage of a non-terrestrial network NTN is lost.
[0089] In some embodiments, the first distance may be the distance between the location of the terminal and a reference location of the cell.
[0090] In some specific embodiments, the cell may be a serving cell of the terminal, and the first distance may be a distance between the location of the terminal and a reference location of the serving cell of the terminal. For example, when the terminal is in a camped normally state, the cell may be the serving cell of the terminal.
[0091] In some embodiments, the first event being related to the first distance may include that the first distance may be used to determine whether the first event is satisfied, for example, by comparing the first distance with a first distance threshold to determine whether the first event is satisfied.
[0092] In some embodiments, the first event is considered satisfied when the first distance is greater than or equal to a first distance threshold.
[0093] In some embodiments, the first event-related information includes at least one of the following:
[0094] a first parameter, wherein the first parameter is used to determine a first distance threshold;
[0095] at least one second distance threshold, each second distance threshold being related to at least one of an orbital altitude of a satellite and a coverage area of an NTN cell, the at least one second distance threshold being used to determine the first distance threshold;
[0096] The first distance threshold is used to evaluate whether a condition for performing measurement recording is met, or the first distance threshold is used to evaluate whether a first event is met.
[0097] In some embodiments, the first parameter and the third distance threshold are used to determine the first distance threshold. The third distance threshold may be a distance threshold corresponding to a cell involved in the first distance, such as a distance threshold corresponding to a serving cell of the terminal. Optionally, the third distance threshold is used for location-based measurement initiation by the terminal in a non-connected state.
[0098] In some embodiments, the first parameter can be used to characterize the relationship between the first distance threshold and the third distance threshold, such as a ratio relationship. Optionally, the first parameter can be expressed as a fraction, percentage, or the like. That is, the first parameter can be a scaling factor (or coefficient) of the first distance threshold relative to the third distance threshold. Another example is a difference relationship, such as the first parameter can be an offset value of the first distance threshold relative to the third distance threshold.
[0099] Since the near-far effect is not obvious in NTN, starting measurement based on existing signal measurement results may lead to unnecessary measurement records or omission of necessary measurement records.
[0100] Therefore, in the embodiment of the present application, the terminal may be configured to evaluate whether the first event is satisfied to perform measurement recording, so that measurement recording can be performed in a timely manner when measurement recording is required, thereby reducing unnecessary measurement recording.
[0101] Furthermore, in the embodiment of the present application, the first parameter configured on the network side can enable the first distance threshold determined by the terminal to adapt to NTN cells with different coverage areas, thereby enabling the terminal to perform measurement logging at an appropriate time.
[0102] In some embodiments, the at least one second distance threshold may include at least one of the following:
[0103] a second distance threshold corresponding to a low orbital altitude (e.g., an orbital altitude corresponding to a LEO satellite);
[0104] a second distance threshold corresponding to a medium orbit altitude (e.g., an orbit altitude corresponding to a MEO satellite);
[0105] a second distance threshold corresponding to a high orbital altitude (e.g., an orbital altitude corresponding to a HEO satellite);
[0106] A second distance threshold corresponding to a geosynchronous orbit altitude (eg, an orbit altitude corresponding to a GEO satellite).
[0107] As a specific example, the at least one second distance threshold may include at least one of the following:
[0108] The second distance threshold corresponding to orbital altitudes of 100km-500km;
[0109] The second distance threshold corresponding to orbital altitudes of 500km-1000km;
[0110] The second distance threshold corresponding to orbit altitudes above 1000km.
[0111] In some embodiments, the at least one second distance threshold may include at least one second distance threshold corresponding to the coverage area (or coverage radius) of the NTN cell. For example, the at least one second distance threshold may include a second distance threshold corresponding to the coverage area of the first cell, a second distance threshold corresponding to the coverage area of the second cell, etc., wherein the coverage area of the first cell is larger than the coverage area of the second cell, or the coverage radius of the coverage area of the first cell is larger than the coverage radius of the coverage area of the second cell.
[0112] In some embodiments, the higher the satellite's orbital altitude or the larger the NTN cell coverage area, the larger the corresponding second distance threshold.
[0113] For example, the second distance threshold corresponding to the low orbit altitude is smaller than the second distance threshold corresponding to the medium orbit altitude.
[0114] For another example, the second distance threshold corresponding to the medium orbit altitude is smaller than the second distance threshold corresponding to the high orbit altitude.
[0115] For another example, the second distance threshold corresponding to the first cell coverage area is greater than the second distance threshold corresponding to the second cell coverage area.
[0116] This is because the higher the orbit altitude, the larger the cell coverage range, or in other words, the larger the coverage radius. In this case, if the configured second distance threshold is small, the terminal will perform measurement recording at the wrong time, and will not be able to record the real coverage hole data, and will increase the burden of the terminal performing measurement recording. If the configured second distance threshold is large, the terminal will not perform measurement recording at the actual coverage hole, that is, the terminal will not perform measurement recording at the correct time, and thus cannot provide real coverage hole data to the network, and cannot assist the network in analyzing coverage holes or optimizing network configuration.
[0117] Therefore, in an embodiment of the present application, by configuring a corresponding second distance threshold based on the satellite's orbital altitude and / or the cell coverage area of the NTN, it is convenient for the terminal to determine whether to perform measurement recording based on an appropriate second distance threshold in different NTN cells, and measurement recording can be performed at an appropriate time, and the burden of performing unnecessary measurement recording can be reduced.
[0118] In some embodiments of the present application, the method 400 further includes:
[0119] The terminal determines a first distance threshold according to first event related information.
[0120] In some cases, when the first event-related information includes the first parameter, the terminal determines the first distance threshold according to the first parameter and a third distance threshold corresponding to a serving cell of the terminal.
[0121] For example, the first parameter is used to represent the ratio of the first distance threshold to the third distance threshold, and the product of the first parameter and the third distance threshold may be determined as the first distance threshold.
[0122] For another example, the first parameter is used to represent the difference between the first distance threshold and the third distance threshold, and the sum of the first parameter and the third distance threshold can be determined as the first distance threshold.
[0123] In other cases, when the first event-related information includes the at least one second distance threshold, the terminal determines the first distance threshold based on satellite assistance information of the serving cell. Optionally, the satellite assistance information of the serving cell may include ephemeris information of the serving cell.
[0124] For example, the terminal may obtain the orbital altitude of the satellite based on satellite auxiliary information (such as ephemeris information) of the serving cell, and then determine the second distance threshold corresponding to the orbital altitude as the first distance threshold.
[0125] Exemplarily, if the terminal determines that the satellite of the serving cell is a GSO according to the ephemeris information of the serving cell, the first distance threshold is determined to be the second distance threshold corresponding to the GSO.
[0126] In some embodiments, when the first configuration includes information related to the first event, the terminal performs measurement logging according to the first configuration, including:
[0127] When the first distance is greater than or equal to a first distance threshold (ie, a first event is satisfied), the terminal performs measurement logging, where the first distance is the distance between the position of the terminal and a reference position of a serving cell of the terminal.
[0128] In some embodiments, performing measurement logging according to the first configuration includes:
[0129] When at least one of the following conditions is met, the terminal performs measurement recording according to the first event related information:
[0130] The terminal obtains a third distance threshold corresponding to the serving cell of the terminal;
[0131] The terminal obtains a reference position of the serving cell;
[0132] The terminal obtains the location of the terminal.
[0133] In some embodiments, the terminal may obtain the third distance threshold corresponding to the serving cell of the terminal, which may include:
[0134] The terminal obtains system information of the serving cell (for example, for the NR system, obtains SIB19), wherein the system information of the serving cell includes a third distance threshold (distanceThresh) corresponding to the serving cell, and the third distance threshold is used for the terminal to initiate location-based measurement in a non-connected state.
[0135] In some embodiments, the terminal acquiring the reference position of the serving cell may include:
[0136] The terminal obtains system information of the serving cell (e.g., a system information block (SIB)), wherein the system information of the serving cell includes a first reference location. In this case, the terminal may determine that the first reference location is a reference location of the serving cell, optionally, the serving cell is a quasi-earth-fixed cell; or
[0137] The terminal obtains system information of the serving cell (for example, a system information block (SIB)), where the system information of the serving cell includes a second reference position (for example, movingreferenceLocation). In this case, the terminal can determine the reference position of the serving cell based on the second reference position, the ephemeris information of the serving cell, and the reference time (for example, epoch time). Optionally, the serving cell is an earth-moving cell.
[0138] In some embodiments, the first reference location is used in an NTN quasi-Earth fixed system, and the terminal initiates location-based measurement in a non-connected state. Optionally, the system information of the serving cell may include a referenceLocation parameter, and the reference location indicated by the referenceLocation parameter may be determined as the first reference location.
[0139] In some embodiments, the second reference location may be a reference location of a serving cell at a reference time (e.g., epoch time) provided by an earth-moving system, for initiating location-based measurements by the terminal in a non-connected state. Optionally, the system information of the serving cell may include a movingReferenceLocation parameter, and the reference location indicated by the movingReferenceLocation parameter may be determined as the second reference location.
[0140] In some embodiments, the system information of the serving cell may be system information including satellite assistance information, such as SIB19 in the NR system or SIB31 in the LTE system.
[0141] In some embodiments of the present application, the first region-related information includes at least one of the following:
[0142] At least one TN area identifier (tn-AreaId), where each TN area identifier is used to indicate a TN area;
[0143] At least one second parameter, wherein each second parameter is associated with at least one TN region identifier, and the second parameter is used to determine the first region, for example, the second parameter is used to determine a distance threshold corresponding to the first region;
[0144] At least one geographical area information is used to determine at least one geographical area.
[0145] Optionally, the geographic area information may include a reference location of the geographic area and a distance threshold of the geographic area. That is, a geographic area may be represented by the reference location and the distance threshold. Optionally, the distance threshold of the geographic area may be a predefined value. In this case, the first area-related information may not include the distance threshold of the geographic area.
[0146] Optionally, the geographic area information may include multiple reference locations, that is, a geographic area may be represented by multiple reference locations.
[0147] In some embodiments, when the first configuration includes information related to the first area, the terminal performing measurement logging according to the first configuration includes:
[0148] In case the terminal is in the first area, the terminal performs measurement logging.
[0149] In some embodiments, the method 400 further includes:
[0150] The terminal determines the first area according to first area related information.
[0151] Case 1: The first area is determined according to the TN area. Case 1-1: The terminal determines the first area according to at least one TN area identifier.
[0152] For example, the terminal determines the TN area indicated by the at least one TN area identifier as the first area.
[0153] In this case, it can be considered that the first area includes at least one TN area, and the first area can correspond to at least one reference position and at least one distance threshold, the at least one reference position is the reference position of the at least one TN area, and the at least one distance threshold is the distance threshold of the at least one TN area.
[0154] Case 1-2: The terminal determines the first area according to the TN area indicated by the at least one TN area identifier and the associated second parameter.
[0155] In this case, the first area can be considered to include at least one sub-area, each sub-area is determined based on a TN area and an associated second parameter. Each sub-area corresponds to a reference position and a distance threshold. The reference position corresponding to each sub-area is the reference position of the corresponding TN area, and the distance threshold corresponding to each sub-area is determined based on the distance threshold of the corresponding TN area and the second parameter.
[0156] It can be seen from this that the TN area in case 1-1 can also be considered as a sub-area of the first area. The difference from case 1-2 is that: the distance threshold of the sub-area is determined according to the distance threshold corresponding to the TN area, or according to the second parameter and the distance threshold corresponding to the TN area.
[0157] In some embodiments, the second parameter can be used to characterize the relationship between the distance threshold corresponding to the sub-region of the first region and the distance threshold corresponding to the TN region, such as a ratio relationship. Optionally, the second parameter can be expressed as a fraction, percentage, or the like, that is, the second parameter can be a scaling factor (or coefficient) of the distance threshold corresponding to the sub-region relative to the distance threshold corresponding to the TN region. For another example, a difference relationship can be used, for example, the second parameter can be an offset value of the distance threshold corresponding to the sub-region relative to the distance threshold corresponding to the TN region.
[0158] Case 2: The first region is determined based on a geographical area.
[0159] Case 2-1: The terminal determines the first area according to at least one piece of geographic area information, where the geographic area information includes a reference location and a distance threshold.
[0160] For example, the terminal may determine a geographic area based on the reference location and distance threshold of each geographic area. Optionally, the terminal may use the center of the area as the reference location of the geographic area, and the distance between the center and the boundary of the area as the distance threshold of the geographic area. The first area may include the at least one geographic area. That is, each geographic area may be considered a sub-area of the first area, the distance threshold of the sub-area is determined based on the distance threshold of the geographic area, and the reference location of the sub-area is the reference location of the geographic area.
[0161] Case 2-1: The terminal determines the first area according to at least one piece of geographic area information, where the geographic area information includes multiple reference locations.
[0162] For example, the terminal may determine a geographic area based on multiple reference locations in each geographic area information. For example, the geographic area may be an area surrounded by the multiple reference locations. The first area may include the at least one geographic area. Each geographic area may be considered a sub-area of the first area, the distance threshold of the sub-area is determined based on the distance threshold of the geographic area, and the reference location of the sub-area is the reference location of the geographic area.
[0163] In some embodiments, the terminal is in the first area, including at least one of the following:
[0164] The distance between the terminal and any reference position of the TN area is less than or equal to a fourth distance threshold;
[0165] The distance between the terminal and any reference position of the geographical area is less than or equal to a distance threshold of the geographical area;
[0166] The fourth distance threshold is a distance threshold corresponding to the TN area; or, the fourth distance threshold is determined according to the distance threshold corresponding to the TN area and a second parameter associated with the TN area.
[0167] That is, when the distance between the position of the terminal and the reference position of any sub-area in the first area is less than the distance threshold corresponding to the sub-area, it can be considered that the terminal is in the first area.
[0168] In an embodiment of the present application, the first area may refer to an area where the terminal needs to perform measurement recording. Since the coverage area of the NTN cell is much larger than the coverage area of the TN cell, configuring the area where the terminal performs measurement recording in units of NTN cells may cause the terminal to perform unnecessary measurement recording. In an embodiment of the present application, the area where the terminal performs measurement recording can be configured in units of TN areas, which is conducive to achieving refined area configuration and can reduce the burden of the terminal performing unnecessary measurement recording.
[0169] In some embodiments, the second event-related information includes first indication information, where the first indication information is used to instruct the terminal to perform measurement logging when it detects that the terminal loses coverage of the NTN.
[0170] Optionally, the second event may include the terminal detecting that the coverage of the NTN is lost, or it may be considered that the second event is satisfied when the terminal detects that the coverage of the NTN is lost.
[0171] In some embodiments, when the first configuration includes information related to the second event (for example, including first indication information), the terminal performs measurement logging according to the first configuration, including:
[0172] In case the terminal detects that the coverage of the NTN is lost, the terminal performs measurement logging;
[0173] The terminal detects whether it loses NTN coverage based on satellite assistance information.
[0174] In some embodiments, the satellite assistance information can be obtained through system information, for example, in the NR system, through SIB19, and in the LTE system, through SIB31.
[0175] In some embodiments of the present application, before the terminal performs measurement recording, the method 300 further includes:
[0176] The terminal stores the first configuration.
[0177] Optionally, the terminal stores the first configuration to the first variable.

[0183] In some embodiments, the terminal obtains the reference position of the TN area and the distance threshold of the TN area through a first network side device, and the first network side device is a network side device that provides the first configuration.
[0184] For example, the terminal may obtain the reference position of the TN area and the distance threshold of the TN area through the system information (eg, SIB19) of the first network side device.
[0185] In some embodiments, the terminal performs measurement logging, including:

[0192] In some embodiments, the time information of the execution record can be expressed in absolute time, such as Universal Coordinated Time (UTC), or can be expressed in relative time, such as a time offset relative to a reference time, which can be, for example, epoch time.
[0193] In some embodiments, the terminal may detect whether the NTN coverage is restored based on the satellite assistance information.
[0194] Optionally, when the terminal performs measurement logging based on the first event related information, the first information may include a distance between the terminal and a reference position of the first cell.
[0195] Optionally, when the terminal performs measurement logging based on the second event related information, the first information may include at least one first frequency information and / or at least one second frequency information.
[0196] In some embodiments, the at least one first frequency domain information is a subset of the third frequency information. For example, the at least one first frequency domain information can be used to indicate a frequency detected by the terminal in the third frequency information when the terminal recovers coverage of the NTN.
[0197] In some embodiments, the at least one second frequency domain information is a subset of the third frequency information. For example, the at least one second frequency domain information can be used to indicate frequencies that the terminal has not detected in the third frequency information when the terminal recovers coverage of the NTN.
[0198] In some embodiments, the third frequency information is used to indicate at least one frequency. The third frequency information may be configured by a network-side device, for example, auxiliary information configured by the network-side device before the terminal loses coverage. Optionally, the third frequency information may be auxiliary information for discontinuous coverage. Optionally, for an LTE system, the third frequency information may be carrierFreqList in SIB32.
[0199] In some embodiments, when the terminal recovers the coverage of the NTN, it may perform frequency detection based on the third frequency information and record detected frequencies and / or undetected frequencies.
[0200] In some embodiments, the first cell includes at least one of the following:
[0201] The cell where the terminal last resided;
[0202] The cell in which the terminal currently resides;
[0203] A neighboring cell of the serving cell of the terminal.
[0204] For example, when the terminal is in a camped normally state, the first cell may include a cell in which the terminal is currently camped (or in other words, a serving cell of the terminal) and / or a neighboring cell of the serving cell of the terminal.
[0205] For another example, when the terminal is in any cell selection state, the first cell may include the cell where the terminal resided most recently.
[0206] In some embodiments, the method 400 further includes:

[0232] In the embodiment of FIG5 , the first configuration includes information related to the first event. As shown in FIG5 , the following steps may be included:
[0233] S501, the terminal receives a first configuration sent by a network side device, where the first configuration is used to configure a condition for the terminal to perform measurement logging, for example, a condition for the terminal to perform measurement logging in a non-connected state (eg, RRC_IDLE state or RRC_INACTIVE state).

The first configuration includes information related to a first event, a first area, and a second event, wherein the first event is related to the distance between the terminal and the reference position of the cell. Therefore, the terminal can use the information related to the first event to determine whether the terminal is located within the coverage of the cell.

Therefore, it can be determined whether the terminal is within the first area based on the information related to the first area. The second event is related to the terminal detecting the loss of NTN coverage. Therefore, the terminal can determine whether the terminal has lost NTN coverage based on the information related to the second event. The terminal can perform measurement recording based on the first configuration, which can enable the terminal to obtain rich coverage vulnerability data, thereby assisting network-side equipment in analyzing network coverage vulnerabilities or optimizing network configurations.
