Furthermore, objects distinguished by “first” and “second” are generally of a single category, and the number of objects is not limited, for example, a first object may be one or more first objects.

[0026] The technical solutions in the embodiments of the present disclosure are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are merely some rather than all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present disclosure fall within the protection scope of the present disclosure.

[0027] To facilitate a clearer understanding of the technical solutions of various embodiments of the present disclosure, some technical content related to the embodiments of the present disclosure is first introduced.

[0028] 1. MDT Measurement Collection Reporting of UE

[0029] MDT measurement collection reporting of a UE includes two types: immediate MDT (Immediate MDT) measurement collection reporting, and logged MDT (Logged MDT) measurement collection reporting. Both types of MDT measurement collection reporting are configured, managed, and delivered by a network side.

[0030] After configuration information for Immediate MDT measurement collection reporting is delivered to a base station node, radio resource management (Radio Resource Management, RRM) measurement configuration and reporting procedures are reused over an air interface. The UE receives relevant MDT measurement configuration information in a radio resource control (Radio Resource Control, RRC) reconfiguration message, and reports a measurement result to a base station side immediately after completing measurement result collection.

[0031] After configuration information for Logged MDT measurement collection reporting is delivered to the base station node, the configuration information is delivered to the UE over the air interface using a LoggedMeasurementConfiguration (logged measurement configuration) message. The UE starts measurement logging only after entering an idle state or an inactive state, and stores logged results at a UE side. After the UE returns to a connected state, the UE has an opportunity to indicate to a network side that relevant logged MDT results are stored, and then sends them to the network side.

[0032] From another dimension, MDT measurement collection reporting of the UE may further be classified into two usages: signalling based MDT (Signalling based MDT) measurement collection reporting, and management based MDT (Management based MDT) measurement collection reporting.

[0033] Signalling based MDT measurement collection reporting is used to track signal conditions of a single UE. Its MDT configuration is forwarded layer by layer by an operator through core network nodes. In a new radio (New Radio, NR) system, the MDT configuration is transmitted to the base station side through core network nodes such as a unified data management (Unified Data Management, UDM) and an access and mobility management function (Access and Mobility Management Function, AMF). For logged MDT measurement collection reporting, the base station sends MDT configuration information to the UE, and the UE performs measurement collection subsequently, and then reports the same. For immediate MDT measurement collection reporting, the base station sends partial information related to UE measurement in the MDT configuration to the UE.

[0034] Management based MDT measurement collection reporting is used to collect overall signal conditions within a certain area coverage. Its MDT configuration is directly sent by the operator to an involved base station side. According to MDT configuration information, the base station side may select some or all UEs to perform relevant MDT data measurement collection. For Logged MDT measurement collection reporting, the base station sends the MDT configuration information to selected UEs, which perform measurement collection subsequently and report the same. For Immediate MDT measurement collection reporting, the base station sends partial information related to UE measurement in the MDT configuration to the UE.

[0035] 2. Area Restriction for MDT Configuration

[0036] MDT configuration includes area restriction information for MDT measurement collection of the UE. For Signalling based MDT measurement collection reporting, the area restriction information may be carried in an interface signaling transmitted to the base station through a core network node and in air interface configuration for Signalling based logged MDT (signalling based logged MDT) measurement collection reporting. For Management based MDT measurement collection reporting, the area restriction information is not transmitted through the core network node, and the area restriction information may be carried in air interface configuration for Management based logged MDT (management based logged MDT) measurement collection reporting.

[0037] Area restriction contents of the MDT configuration include the following:a. restriction information for a serving cell where the UE is located. For example, the UE is restricted to perform MDT data measurement collection only when its serving cell is in a PLMN / SNPN / TA / cell list configured by a network.b. restriction information for a neighboring cell. For example, in a case where the UE is allowed to perform MDT data measurement collection, a frequency point and a cell identifier of the neighboring cell for which the UE may perform measurement collection are restricted.

[0038] 3. Scenario Classification of Non-Terrestrial Network (Non-Terrestrial Network, NTN) Service Links

[0039] Earth-fixed (Earth-fixed) scenario: a satellite remains stationary relative to a fixed position on the ground, so a beam providing coverage continuously covers a same geographical area. In this scenario, mobility and other behaviors of a UE in an NTN cell are substantially consistent with those in a terrestrial network (Terrestrial Network, TN) cell.

[0040] Quasi-Earth-fixed (Quasi-Earth-fixed) scenario: a beam providing coverage covers a geographical area for a limited time and covers another geographical area for another limited time. In this scenario, a ground NTN area covered by the beam does not move or change for a certain period, and is covered by another beam in a subsequent period.

[0041] Earth-moving (Earth-moving) scenario: coverage is provided by a beam with a coverage area sliding on a surface of the earth. Since a satellite orbit is not synchronized with the Earth’s rotation, the NTN cell in this scenario moves continuously.

[0042] 4. Cell Reselection Enhancement for Quasi-Earth-fixed Scenario or Earth-moving Scenario

[0043] For cell reselection enhancement in the Quasi-Earth-fixed scenario, a solution of broadcasting reference location information of a cell (serving cell or neighboring cell) in system information is introduced. The reference location information is associated with delivered time information, epoch time (epoch time). If a UE has valid location information, using a distance between the UE and the reference location of the cell (serving cell and / or neighboring cell) is supported to assist cell reselection. A service stop time t-Service of the serving cell is further introduced, so that the UE triggers measurement of the neighboring cell in a timely manner. The service stop time of the serving cell is broadcast to the UE via the system information.

[0044] For cell reselection enhancement in the Earth-moving scenario, a solution of providing moving reference point information (movingReferenceLocation) at a certain time (epoch time) to a terminal is introduced. The terminal may estimate a real-time cell reference point position for a future period according to information such as ephemeris, epoch time, movingReferenceLocation and so on.

[0045] 5. Reselection Enhancement from NTN Cell to TN Cell

[0046] An area of the NTN cell is much larger than that of the TN cell. The NTN cell may have many TN neighboring cells, and these neighboring cells may be distributed only at certain positions of the NTN cell. At positions without TN deployment, to avoid unnecessary power consumption caused by measurement of these frequency points, reselection enhancement from the NTN cell to the TN cell is introduced. Location information of a TN coverage area is broadcast for the NTN cell, and the UE may determine whether to start measurement of corresponding frequency points according to whether TN coverage exists around. The TN coverage area is constituted by an area list, and information of each TN coverage area includes: a TN area identifier (e.g., tn-AreaId-r18), a reference point parameter (e.g., tn-ReferenceLocation-r18), and a radius parameter (e.g., tn-DistanceRadius-r18).

[0047] In the above related art, the restriction range in the MDT configuration is divided into three levels: the network level (the network includes PLMN and / or SNPN), the TA level, and the cell level. However, for the NTN cell, a geographical range covered by a single NTN cell is excessively large. For different NTN scenarios, satellites or beams covering an NTN area may change, or an NTN satellite coverage area may move. Adopting the MDT configuration in the above related art is not conducive for operators to collect MDT results in a targeted manner, and may cause waste of power consumption overhead during MDT measurement collection by the UE.

[0048] For a TN scenario, although a geographical range of the TN cell is smaller than that of the NTN cell, MDT configuration solution in the above related art is also not conducive for operators to collect MDT results in a targeted manner, and also has a problem of possible waste of power consumption overhead during MDT measurement collection by the UE.

[0049] To address the above problems, the present disclosure provides solutions, and the solutions may be applicable to both NTN scenario and TN scenario. The network side can configure a range for the terminal to perform MDT measurement collection in a targeted manner as required, thereby improving the flexibility of MDT measurement collection and reducing unnecessary terminal power consumption.

[0050] FIG. 1 is a schematic flowchart of an MDT measurement collection method provided by an embodiment of the present disclosure, applied to a terminal. As shown in FIG. 1, the method includes the following steps.

[0051] Step 100: receiving MDT configuration information sent by a network device, where the MDT configuration information includes restriction information for MDT measurement collection, and the restriction information includes at least one of cell type restriction information, area restriction information, or time restriction information.

[0052] Step 101: performing MDT measurement collection based on the MDT configuration information.

[0053] Specifically, the network device (e.g., a base station) in the present disclosure may carry the restriction information for MDT measurement collection in the MDT configuration information sent to the terminal, so as to configure a range for the terminal to perform MDT measurement collection in a targeted manner.

[0054] In the present disclosure, MDT measurement collection refers to: at a terminal side, collection and logging of terminal available measurement results (measurements or measurement results), measurement configurations, measurement-related information and the like for MDT purposes; and / or at the terminal side, performing terminal measurement only for MDT purposes, and collecting and logging relevant measurement results, measurement configurations, measurement-related information and the like.

[0055] In some embodiments, the MDT configuration information may be NTN-related MDT configuration information.

[0056] In some embodiments, the cell type restriction information includes one or more of the following indication information.

[0057] (1) First indication information, where the first indication information is used to indicate that the terminal measures and collects MDT data of a TN cell and / or an NTN cell.

[0058] For example, the network device carries the first indication information in the MDT configuration information sent to the terminal, and the first indication information indicates that the terminal collects measurement results of the TN cell only, or indicates that the terminal collects measurement results of the NTN cell only, or indicates that the terminal collects measurement results of both the NTN cell and the TN cell. The terminal may perform MDT measurement collection for a restricted cell type according to indication of the first indication information.

[0059] (2) Second indication information, where the second indication information is used to indicate whether the terminal is allowed to measure and collect MDT data of the NTN cell in a case where the terminal camps on or is connected to the TN cell.

[0060] For example, the network device carries the second indication information in the MDT configuration information sent to the terminal, and the second indication information indicates whether the terminal is allowed to collect measurement results on an NTN frequency point or the NTN cell when the terminal camps on or is connected to the TN cell. When the terminal camps on or is connected to the TN cell, the terminal may determine whether to perform NTN-related MDT measurement collection according to indication of the second indication information.

[0061] (3) Third indication information, where the third indication information is used to indicate whether the terminal is allowed to measure and collect MDT data of the TN cell in a case where the terminal camps on or is connected to the NTN cell.

[0062] For example, the network device carries the third indication information in the MDT configuration information sent to the terminal, and the third indication information indicates whether the terminal is allowed to collect measurement results on a TN frequency point or the TN cell when the terminal camps on or is connected to the NTN cell. When the terminal camps on or is connected to the NTN cell, the terminal may determine whether to perform TN-related MDT measurement collection according to indication of the third indication information.

[0063] By indicating the cell type restriction information for MDT measurement collection through one or more of the first indication information, the second indication information, and the third indication information, various targeted MDT measurement collection requirements can be satisfied, and the flexibility of MDT measurement collection is improved.

[0064] In some embodiments, the area restriction information includes one or more of the following.

[0065] (1) A TN area identifier. The TN area identifier is used to identify a TN coverage area.

[0066] In some implementations, an area for MDT measurement collection may be indicated in combination with “information of a TN coverage area broadcast by a network for an NTN cell” mentioned in related art. For example, in a case where the network broadcasts the information of the TN coverage area for the NTN cell, if an area for MDT measurement collection includes the TN coverage area, the network device may directly carry a TN area identifier corresponding to the area for MDT measurement collection in the MDT configuration information. The terminal may obtain a specific area range according to the TN area identifier carried in the MDT configuration information in combination with the information of the TN coverage area broadcast by the network.

[0067] (2) A restricted area list. The restricted area list is an area list for MDT measurement collection.

[0068] In some embodiments, each entry in the restricted area list includes a reference point parameter and a radius parameter. The reference point parameter is used to determine a reference point position, and the radius parameter is used to determine a radius of an area range to be restricted, which may be a radius value, a distance threshold, or the like. A specific area range can be determined by combining the reference point position and the radius.

[0069] For example, for the NTN cell, the restricted area list may be used for MDT data collection within a partial geographical position range in the NTN cell, avoiding MDT collection for unnecessary geographical positions and saving terminal power consumption. For the TN cell, the restricted area list may include MDT data collection for geographical ranges corresponding to multiple TN cells, without delivering cell identifiers of these cells, saving configuration signaling.

[0070] In some embodiments, each entry in the restricted area list includes a logical identifier (Identifier, ID) mapped to a fixed area. The fixed area is an area mapped according to a certain mapping rule, such as an area mapped based on a nine-grid format, three-sector angle of a base station, or the like. The terminal and the network device follow the same mapping rule, which may be agreed upon in a protocol or indicated by the network side to the terminal.

[0071] For example, both the terminal and the network device divide the NTN cell according to a nine-grid mapping rule. One NTN cell may be divided into 9 areas, and each area corresponds to a logical identifier. The network device may indicate that the terminal performs MDT measurement only for one or more areas in the NTN cell, e.g., performing MDT measurement collection only for an area with a mapped logical identifier of 0.

[0072] (3) Restricted frequency point information. The restricted frequency point information is used to indicate which frequency points the terminal performs MDT measurement collection for.

[0073] Since TN and NTN are basically deployed on different frequency points, in some implementations, the restricted frequency point information may be used to indicate MDT measurement collection for the TN cell or the NTN cell.

[0074] In some embodiments, the restricted frequency point information is common restricted frequency point information for performing MDT measurement collection for a serving cell and performing MDT measurement collection for a neighboring cell, that is, MDT measurement collection for the serving cell of the terminal and the neighboring cell shares a same set of restricted frequency point information. Or, the restricted frequency point information includes restricted frequency point information configured for performing MDT measurement collection for the serving cell, and / or restricted frequency point information configured for performing MDT measurement collection for the neighboring cell, that is, MDT measurement collection for the serving cell of the terminal and the neighboring cell may each be separately configured with or without respective restricted frequency information.

[0075] A restricted area range for MDT measurement collection is indicated through a combination of one or more of the TN area identifier, the restricted area list, and the restricted frequency point information, thereby improving the flexibility of MDT configuration and saving signaling overhead as much as possible.

[0076] In some embodiments, the time restriction information includes any one of the following.

[0077] (1) Deadline information for measurement collection. The deadline information for measurement collection is used to indicate a deadline time point for the terminal to perform MDT measurement collection.

[0078] In some implementations, for NTN-related MDT measurement collection, the deadline time point for measurement collection may be a time calculated by the network at which the NTN cell ends covering a certain area position.

[0079] When the MDT configuration information indicates only the deadline information for measurement collection, the terminal may determine a start time point for MDT measurement collection in other manners, such as protocol agreement: the start time point for the terminal to perform MDT measurement collection is when the terminal receives the MDT configuration information, or when a certain condition is satisfied (e.g., when the terminal enters an idle state or an inactive state, or when the terminal enters a network-configured cell, or when the terminal enters an area range restricted by the MDT configuration information, etc.).

[0080] (2) Start time information for measurement collection and the deadline information for measurement collection. The start time information for measurement collection is used to indicate a start time point for the terminal to perform MDT measurement collection.

[0081] In some implementations, for NTN-related MDT measurement collection, a start time point for measurement collection may be a time calculated by the network at which the NTN cell covers a certain area position; the deadline time point for measurement collection may be a time calculated by the network at which the NTN cell ends covering the certain area position.

[0082] (3) The start time information for measurement collection and duration information for measurement collection. The duration information for measurement collection is used to indicate a duration for the terminal to perform MDT measurement collection.

[0083] In some implementations, for NTN-related MDT measurement collection, the start time point for measurement collection may be a time calculated by the network at which the NTN cell covers a certain area position; the deadline time point calculated according to the duration information for measurement collection may be a time calculated by the network at which the NTN cell ends covering the certain area position.

[0084] In some embodiments, for the Earth moving scenario, since a position of the NTN cell continuously changes in this scenario, to avoid unnecessary power consumption, the network may configure the terminal to perform MDT measurement collection only within a set time according to ephemeris information and the like (by carrying the time restriction information in the MDT configuration information). For other time, since the NTN cell required for the terminal to measure has not covered an area where the network desires to perform MDT measurement collection, the measurement collection behavior of the terminal may be stopped.

[0085] In some embodiments, for the Quasi-Earth-fixed scenario, since satellites or beams covering the NTN cell may be different in different time periods in this scenario, for targeted measurement, the network may configure the terminal to perform MDT measurement collection only within a set time according to ephemeris information and the like (by carrying the time restriction information in the MDT configuration information). For other time, e.g., a time point of switching satellites or beams, since the NTN cell may be covered by a different satellite or beam, the measurement collection behavior of the terminal may be stopped.

[0086] A specific indication manner or time format of the time restriction information is not limited in the present disclosure, and existing parameter information may be partially reused, or indication may be performed through newly defined time parameters, etc. For example, a time format relative to t-Service (the service stop time of the serving cell) may be used to indicate the start time point for measurement collection or the deadline time point for measurement collection, a time format of epoch time may be used to save signaling, or a time format of coordinated universal time (Coordinated Universal Time, UTC) may be directly configured, etc.

[0087] By configuring one or more of the start time information for measurement collection, the deadline information for measurement collection, and the duration information for measurement collection, a time period for the terminal to perform MDT measurement collection can be indicated more flexibly, thereby avoiding waste of terminal power caused by continuous measurement collection at unnecessary time.

[0088] In some embodiments, the restriction information is one or more sets of restriction information, each set of the restriction information is associated with one or more cells, or each set of the restriction information is associated with one or more tracking areas, or each set of the restriction information is associated with one or more networks.

[0089] For example, the MDT configuration information carries one or more of multiple sets of cell type restriction information, multiple sets of area restriction information, and multiple sets of time restriction information. One set of area restriction information and one set of time restriction information are configured for each cell or cell group, or one set of cell type restriction information and one set of area restriction information are configured for each network or network group (the network includes PLMN and / or SNPN), or one set of time restriction information is configured for each TA or TA list, etc.

[0090] In the present disclosure, the cell type restriction information, the area restriction information, and the time restriction information may be arranged and combined according to existing restriction range levels in MDT configuration at different network / tracking area / cell levels, and the terminal may perform MDT measurement collection based on combined restriction information.

[0091] By configuring one or more sets of restriction information for MDT measurement collection, and associating them with cells, tracking areas, or networks, different MDT measurement collection requirements for different cells, tracking areas, or networks can be satisfied, thereby improving the flexibility of MDT measurement collection.

[0092] In the embodiments of the present disclosure, the area restriction information and / or the time restriction information carried in the MDT configuration information may partially reuse parameter information in existing NTN / TN-related configurations, or the network may deliver newly defined restriction information to the terminal, which is not limited in the present disclosure.

[0093] According to the MDT measurement collection method provided by the embodiments of the present disclosure, by carrying at least one of the cell type restriction information, the area restriction information, or the time restriction information for MDT measurement collection in the MDT configuration information, a range for the terminal to perform MDT measurement collection can be configured in a targeted manner, thereby improving the flexibility of MDT measurement collection, and reducing unnecessary terminal power consumption.

[0094] In some embodiments, the method further includes the following operation.

[0095] Reporting an MDT measurement collection report, where the MDT measurement collection report includes one or more of the following.

[0096] (1) A type of the serving cell of the terminal when collecting an MDT result.

[0097] For example, after performing MDT measurement based on the MDT configuration information, the terminal reports the MDT measurement collection report. The MDT measurement collection report includes the MDT result, and also carries the type of the serving cell of the terminal when the terminal collects the MDT result, e.g., the serving cell of the terminal when the terminal collects the MDT result is the TN cell or the NTN cell.

[0098] (2) A satellite identifier of a serving satellite of the terminal when collecting the MDT result.

[0099] For example, after performing MDT measurement based on the MDT configuration information, the terminal reports the MDT measurement collection report. The MDT measurement collection report includes the MDT result, and also carries the satellite identifier of the serving satellite of the terminal when the terminal collects the MDT result. The satellite identifier indicates which satellite serves the terminal when the terminal collects the MDT result.

[0100] (3) Geographic location information of the terminal when collecting the MDT result.

[0101] For example, after performing MDT measurement based on the MDT configuration information, the terminal reports the MDT measurement collection report. The MDT measurement collection report includes the MDT result, and also carries the geographic location information of the terminal when the terminal collects the MDT result, so that the network can learn a position of the terminal when collecting the MDT result.

[0102] (4) The MDT configuration information.

[0103] For example, after performing MDT measurement based on the MDT configuration information, the terminal reports the MDT measurement collection report. The MDT measurement collection report includes the MDT result, and also carries corresponding MDT configuration information to indicate the MDT configuration information based on which the MDT result is obtained.

[0104] Taking Logged MDT measurement collection reporting as an example, after configuration information for Logged MDT measurement collection reporting is delivered to the terminal, the terminal starts measurement logging after entering an idle state or an inactive state, and stores logging results at the terminal side. After the terminal returns to a connected state, the terminal has an opportunity to report stored Logged MDT results to the network side. In this case, the terminal may carry the MDT configuration information in the MDT measurement collection report, and the MDT configuration information is associated with the Logged MDT results, so that the network side can learn the MDT configuration information based on which each Logged MDT result is obtained.

[0105] For Immediate MDT measurement collection reporting, the terminal reports in a timely manner, so the network side can associate content reported by the terminal with cell information at that time and MDT configuration information, and report to an operator collection node.

[0106] (5) A result calculated by the terminal through calculation based on the MDT configuration information.

[0107] For example, after receiving the MDT configuration information from the network side, the terminal independently calculates results such as a reference time, a cell reference point position for each Earth-moving cell according to ephemeris information and the like, and carries these results obtained by calculating in the MDT measurement collection report for reporting when reporting the MDT measurement collection report.

[0108] By reporting various information related to the MDT measurement collection report when reporting the report, more auxiliary information is provided for the network side to analyze the MDT measurement collection report, which helps to improve the comprehensiveness and accuracy of MDT measurement collection report analysis.

[0109] FIG. 2 is a schematic flowchart of an MDT configuration method provided by an embodiment of the present disclosure, applied to a network device (e.g., a base station). As shown in FIG. 2, the method includes the following steps.

[0110] Step 200: sending MDT configuration information to a terminal, where the MDT configuration information includes restriction information for MDT measurement collection, and the restriction information includes at least one of cell type restriction information, area restriction information, or time restriction information.

[0111] Specifically, the network device in the present disclosure may carry the restriction information for MDT measurement collection in the MDT configuration information sent to the terminal, so as to configure a range for the terminal to perform MDT measurement collection in a targeted manner.

[0112] In some embodiments, the MDT configuration information may be NTN-related MDT configuration information.

[0113] In some embodiments, the cell type restriction information includes one or more of the following indication information.

[0114] (1) First indication information, where the first indication information is used to indicate that the terminal measures and collects MDT data of a TN cell and / or an NTN cell.

[0115] For example, the network device carries the first indication information in the MDT configuration information sent to the terminal, and the first indication information indicates that the terminal collects measurement results of the TN cell only, or indicates that the terminal collects measurement results of the NTN cell only, or indicates that the terminal collects measurement results of both the NTN cell and the TN cell. The terminal may perform MDT measurement collection for a restricted cell type according to indication of the first indication information.

[0116] (2) Second indication information, where the second indication information is used to indicate whether the terminal is allowed to measure and collect MDT data of the NTN cell in a case where the terminal camps on or is connected to the TN cell.

[0117] For example, the network device carries the second indication information in the MDT configuration information sent to the terminal, and the second indication information indicates whether the terminal is allowed to collect measurement results on an NTN frequency point or the NTN cell when the terminal camps on or is connected to the TN cell. When the terminal camps on or is connected to the TN cell, the terminal may determine whether to perform NTN-related MDT measurement collection according to indication of the second indication information.

[0118] (3) Third indication information, where the third indication information is used to indicate whether the terminal is allowed to measure and collect MDT data of the TN cell in a case where the terminal camps on or is connected to the NTN cell.

[0119] For example, the network device carries the third indication information in the MDT configuration information sent to the terminal, and the third indication information indicates whether the terminal is allowed to collect measurement results on a TN frequency point or the TN cell when the terminal camps on or is connected to the NTN cell. When the terminal camps on or is connected to the NTN cell, the terminal may determine whether to perform TN-related MDT measurement collection according to indication of the third indication information.

[0120] By indicating the cell type restriction information for MDT measurement collection through one or more of the first indication information, the second indication information, and the third indication information, various targeted MDT measurement collection requirements can be satisfied, and the flexibility of MDT measurement collection is improved.

[0121] In some embodiments, the area restriction information includes one or more of the following.

[0122] (1) A TN area identifier. The TN area identifier is used to identify a TN coverage area.

[0123] In some implementations, an area for MDT measurement collection may be indicated in combination with “information of a TN coverage area broadcast by a network for an NTN cell” mentioned in related art. For example, in a case where the network broadcasts the information of the TN coverage area for the NTN cell, if an area for MDT measurement collection includes the TN coverage area, the network device may directly carry a TN area identifier corresponding to the area for MDT measurement collection in the MDT configuration information. The terminal may obtain a specific area range according to the TN area identifier carried in the MDT configuration information in combination with the information of the TN coverage area broadcast by the network.

[0124] (2) A restricted area list. The restricted area list is an area list for MDT measurement collection.

[0125] In some embodiments, each entry in the restricted area list includes a reference point parameter and a radius parameter. The reference point parameter is used to determine a reference point position, and the radius parameter is used to determine a radius of an area range to be restricted, which may be a radius value, a distance threshold, or the like. A specific area range can be determined by combining the reference point position and the radius.

[0126] For example, for the NTN cell, the restricted area list may be used for MDT data collection within a partial geographical position range in the NTN cell, avoiding MDT collection for unnecessary geographical positions and saving terminal power consumption. For the TN cell, the restricted area list may include MDT data collection for geographical ranges corresponding to multiple TN cells, without delivering cell identifiers of these cells, saving configuration signaling.

[0127] In some embodiments, each entry in the restricted area list includes a logical identifier mapped to a fixed area. The fixed area is an area mapped according to a certain mapping rule, such as an area mapped based on a nine-grid format, three-sector angle of a base station, or the like. The terminal and the network device follow the same mapping rule, which may be agreed upon in a protocol or indicated by the network side to the terminal.

[0128] For example, both the terminal and the network device divide the NTN cell according to a nine-grid mapping rule. One NTN cell may be divided into 9 areas, and each area corresponds to a logical identifier. The network device may indicate that the terminal performs MDT measurement only for one or more areas in the NTN cell, e.g., performing MDT measurement collection only for an area with a mapped logical identifier of 0.

[0129] (3) Restricted frequency point information. The restricted frequency point information is used to indicate which frequency points the terminal performs MDT measurement collection for.

[0130] Since TN and NTN are basically deployed on different frequency points, in some implementations, the restricted frequency point information may be used to indicate MDT measurement collection for the TN cell or the NTN cell.

[0131] In some embodiments, the restricted frequency point information is common restricted frequency point information for performing MDT measurement collection for a serving cell and performing MDT measurement collection for a neighboring cell, that is, MDT measurement collection for the serving cell of the terminal and the neighboring cell shares a same set of restricted frequency point information. Or, the restricted frequency point information includes restricted frequency point information configured for performing MDT measurement collection for the serving cell, and / or restricted frequency point information configured for performing MDT measurement collection for the neighboring cell, that is, MDT measurement collection for the serving cell of the terminal and the neighboring cell may each be separately configured with or without respective restricted frequency information.

[0132] A restricted area range for MDT measurement collection is indicated through a combination of one or more of the TN area identifier, the restricted area list, and the restricted frequency point information, thereby improving the flexibility of MDT configuration and saving signaling overhead as much as possible.

[0133] In some embodiments, the time restriction information includes any one of the following.

[0134] (1) Deadline information for measurement collection. The deadline information for measurement collection is used to indicate a deadline time point for the terminal to perform MDT measurement collection.

[0135] In some implementations, for NTN-related MDT measurement collection, the deadline time point for measurement collection may be a time calculated by the network at which the NTN cell ends covering a certain area position.

[0136] When the MDT configuration information indicates only the deadline information for measurement collection, the terminal may determine a start time point for MDT measurement collection in other manners, such as protocol agreement: the start time point for the terminal to perform MDT measurement collection is when the terminal receives the MDT configuration information, or when a certain condition is satisfied (e.g., when the terminal enters an idle state or an inactive state, or when the terminal enters a network-configured cell, or when the terminal enters an area range restricted by the MDT configuration information, etc.).

[0137] (2) Start time information for measurement collection and the deadline information for measurement collection. The start time information for measurement collection is used to indicate a start time point for the terminal to perform MDT measurement collection.

[0138] In some implementations, for NTN-related MDT measurement collection, a start time point for measurement collection may be a time calculated by the network at which the NTN cell covers a certain area position; the deadline time point for measurement collection may be a time calculated by the network at which the NTN cell ends covering the certain area position.

[0139] (3) The start time information for measurement collection and duration information for measurement collection. The duration information for measurement collection is used to indicate a duration for the terminal to perform MDT measurement collection.

[0140] In some implementations, for NTN-related MDT measurement collection, the start time point for measurement collection may be a time calculated by the network at which the NTN cell covers a certain area position; the deadline time point calculated according to the duration information for measurement collection may be a time calculated by the network at which the NTN cell ends covering the certain area position.

[0141] In some embodiments, for the Earth moving scenario, since a position of the NTN cell continuously changes in this scenario, to avoid unnecessary power consumption, the network may configure the terminal to perform MDT measurement collection only within a set time according to ephemeris information and the like (by carrying the time restriction information in the MDT configuration information). For other time, since the NTN cell required for the terminal to measure has not covered an area where the network desires to perform MDT measurement collection, the measurement collection behavior of the terminal may be stopped.

[0142] In some embodiments, for the Quasi-Earth-fixed scenario, since satellites or beams covering the NTN cell may be different in different time periods in this scenario, for targeted measurement, the network may configure the terminal to perform MDT measurement collection only within a set time according to ephemeris information and the like (by carrying the time restriction information in the MDT configuration information). For other time, e.g., a time point of switching satellites or beams, since the NTN cell may be covered by a different satellite or beam, the measurement collection behavior of the terminal may be stopped.

[0143] A specific indication manner or time format of the time restriction information is not limited in the present disclosure, and existing parameter information may be partially reused, or indication may be performed through newly defined time parameters, etc. For example, a time format relative to t-Service (the service stop time of the serving cell) may be used to indicate the start time point for measurement collection or the deadline time point for measurement collection, a time format of epoch time may be used to save signaling, or a time format of UTC time may be directly configured, etc.

[0144] By configuring one or more of the start time information for measurement collection, the deadline information for measurement collection, and the duration information for measurement collection, a time period for the terminal to perform MDT measurement collection can be indicated more flexibly, thereby avoiding waste of terminal power caused by continuous measurement collection at unnecessary time.

[0145] In some embodiments, the restriction information is one or more sets of restriction information, each set of the restriction information is associated with one or more cells, or each set of the restriction information is associated with one or more tracking areas, or each set of the restriction information is associated with one or more networks.

[0146] For example, the MDT configuration information carries one or more of multiple sets of cell type restriction information, multiple sets of area restriction information, and multiple sets of time restriction information. One set of area restriction information and one set of time restriction information are configured for each cell or cell group, or one set of cell type restriction information and one set of area restriction information are configured for each network or network group (the network includes PLMN and / or SNPN), or one set of time restriction information is configured for each TA or TA list, etc.

[0147] By configuring one or more sets of restriction information for MDT measurement collection, and associating them with cells, tracking areas, or networks, different MDT measurement collection requirements for different cells, tracking areas, or networks can be satisfied, thereby improving the flexibility of MDT measurement collection.

[0148] In the embodiments of the present disclosure, the area restriction information and / or the time restriction information carried in the MDT configuration information may partially reuse parameter information in existing NTN / TN-related configurations, or the network may deliver newly defined restriction information to the terminal, which is not limited in the present disclosure.

[0149] According to the MDT configuration method provided by the embodiments of the present disclosure, by carrying at least one of the cell type restriction information, the area restriction information, or the time restriction information for MDT measurement collection in the MDT configuration information, a range for the terminal to perform MDT measurement collection can be configured in a targeted manner, thereby improving the flexibility of MDT measurement collection, and reducing unnecessary terminal power consumption.

[0150] In some embodiments, the method further includes the following operation.

[0151] Receiving an MDT measurement collection report sent by the terminal, where the MDT measurement collection report includes one or more of the following.

[0152] (1) A type of the serving cell of the terminal when collecting an MDT result.

[0153] For example, after performing MDT measurement based on the MDT configuration information, the terminal reports the MDT measurement collection report. The MDT measurement collection report includes the MDT result, and also carries the type of the serving cell of the terminal when the terminal collects the MDT result, e.g., the serving cell of the terminal when the terminal collects the MDT result is the TN cell or the NTN cell.

[0154] (2) A satellite identifier of a serving satellite of the terminal when collecting the MDT result.

[0155] For example, after performing MDT measurement based on the MDT configuration information, the terminal reports the MDT measurement collection report. The MDT measurement collection report includes the MDT result, and also carries the satellite identifier of the serving satellite of the terminal when the terminal collects the MDT result. The satellite identifier indicates which satellite serves the terminal when the terminal collects the MDT result.

[0156] (3) Geographic location information of the terminal when collecting the MDT result.

[0157] For example, after performing MDT measurement based on the MDT configuration information, the terminal reports the MDT measurement collection report. The MDT measurement collection report includes the MDT result, and also carries the geographic location information of the terminal when the terminal collects the MDT result, so that the network can learn a position of the terminal when collecting the MDT result.

[0158] (4) The MDT configuration information.

[0159] For example, after performing MDT measurement based on the MDT configuration information, the terminal reports the MDT measurement collection report. The MDT measurement collection report includes the MDT result, and also carries corresponding MDT configuration information to indicate the MDT configuration information based on which the MDT result is obtained.

[0160] Taking Logged MDT measurement collection reporting as an example, after configuration information for Logged MDT measurement collection reporting is delivered to the terminal, the terminal starts measurement logging after entering an idle state or an inactive state, and stores logging results at the terminal side. After the terminal returns to a connected state, the terminal has an opportunity to report stored Logged MDT results to the network side. In this case, the terminal may carry the MDT configuration information in the MDT measurement collection report, and the MDT configuration information is associated with the Logged MDT results, so that the network side can learn the MDT configuration information based on which each Logged MDT result is obtained.

[0161] For Immediate MDT measurement collection reporting, the terminal reports in a timely manner, so the network side can associate content reported by the terminal with cell information at that time and MDT configuration information, and report to an operator collection node.

[0162] (5) A result calculated by the terminal through calculation based on the MDT configuration information.

[0163] For example, after receiving the MDT configuration information from the network side, the terminal independently calculates results such as a reference time, a cell reference point position for each Earth-moving cell according to ephemeris information and the like, and carries these results obtained by calculating in the MDT measurement collection report for reporting when reporting the MDT measurement collection report.

[0164] By reporting various information related to the MDT measurement collection report when reporting the report, more auxiliary information is provided for the network side to analyze the MDT measurement collection report, which helps to improve the comprehensiveness and accuracy of MDT measurement collection report analysis.

[0165] The methods provided in various embodiments of the present disclosure are based on the same application concept. Therefore, for implementations of the methods, reference may be made to each other, and repeated details will not be elaborated here.

[0166] The methods provided in the foregoing embodiments of the present disclosure are illustrated below through examples of specific application scenarios.

[0167] Example 1: Cell type restriction information.

[0168] In MDT configuration, a measurement collection indication of the NTN cell and / or the TN cell may be carried. The indication manner may be one or more of the following.

[0169] (1) Indicating collection of only measurement results of the TN cell, or collection of only measurement results of the NTN cell, or collection of measurement results of both the NTN cell and the TN cell.

[0170] (2) Indicating whether to allow collection of measurement results on an NTN frequency point or the NTN cell when the UE camps on or is connected to the TN cell.

[0171] (3) Indicating whether to allow collection of measurement results on a TN frequency point or the TN cell when the UE camps on or is connected to the NTN cell.

[0172] Example 2: Area restriction information.

[0173] In MDT configuration, a restriction parameter related to a location area may be carried. The carrying manner may be one or more of the following.

[0174] (1) For a cell for which the network broadcasts TN coverage area information, the area restriction information in the MDT configuration may carry a TN area identifier. This method leverages the existing measurement area scope configured for a TN coverage area in NTN for reselection to TN cell, so MDT measurement collection may be performed mainly for the TN coverage area.

[0175] (2) Area restriction information in the MDT configuration may carry a restricted area list.

[0176] i. Each entry in the list includes a reference point coordinate plus a radius or a threshold.

[0177] In this manner, an area restriction range may be set regardless of a type of a cell for which MDT measurement collection is performed. For the NTN cell, the list may be used for MDT data collection within a partial geographical position range in the NTN cell, avoiding MDT collection for unnecessary geographical positions and saving UE power consumption. For the TN cell, the list may include MDT data collection for geographical ranges corresponding to multiple TN cells, without delivering cell identifiers of these cells, saving configuration signaling.

[0178] ii. Each entry in the list includes a logical ID mapped to a fixed area.

[0179] In this manner, in each NTN cell, a logical ID may be used to map to a fixed area. The fixed area is mapped according to a certain mapping rule, such as a nine-grid format, a three-sector angle of a base station, or the like. Both the UE and the base station divide the NTN cell according to the same mapping rule. The mapping rule may be a default rule between the UE and the network side, or delivered by the network side. For example, the network side configures the UE to divide the NTN cell according to a nine-grid rule, and perform MDT measurement collection only for an area with a mapping ID=0.

[0180] (3) An area range in the MDT configuration may carry restricted frequency point information requiring MDT measurement collection. In this manner, since TN and NTN are basically deployed on different frequency points, carrying relevant frequency point information can explicitly indicate MDT measurement collection for different types of frequency points of TN or NTN. The restricted frequency point information may restrict a serving cell of the UE, and / or restrict a range of neighboring cell MDT data measurement collection performed by the UE:i. the serving cell of the UE and the neighboring cell share a same piece of restricted frequency point information for MDT measurement collection.ii. the serving cell of the UE and the neighboring cell may be separately configured with / not configured with respective restricted frequency point information for MDT measurement collection.

[0181] The foregoing area restriction information may partially reuse existing information in NTN configuration parameters, such as a location reference point movingReferenceLocation of a cell in the Earth-moving scenario.

[0182] Example 3: Time restriction information.

[0183] In MDT configuration, the time restriction information may be carried. The carrying manner may be one or more of the following.

[0184] (1) The carried time restriction information includes deadline information for measurement collection. A start time point for MDT measurement collection of the UE is when MDT-related configuration is received, or when a certain condition is satisfied (e.g., entering an idle state or an inactive state, entering a network-configured cell, or entering a location restricted area in Example 2, etc.). A deadline time point is a time point indicated by the deadline information for measurement collection.

[0185] (2) The carried time restriction information includes start time information for measurement collection plus the deadline information for measurement collection, or the start time information for measurement collection plus duration information for measurement collection. A start time point for measurement collection may be a time calculated by the network at which the NTN cell covers a certain area position, i.e., the start time point for MDT measurement collection. A deadline time point for measurement collection or a deadline time point obtained through calculation according to the duration information for measurement collection may be a time calculated by the network at which the NTN cell ends covering the certain area position, i.e., the deadline time point for MDT measurement collection.

[0186] Carrying the time restriction information for the Earth moving scenario:since a position of the NTN cell continuously changes in the Earth moving scenario, to avoid unnecessary power consumption, the network may configure the UE to perform MDT measurement collection only within a set time according to ephemeris information and the like. For other time, since the NTN cell required for the UE to measure has not covered an area where the network desires to perform MDT measurement collection, the measurement collection behavior of the UE may be stopped.

[0187] Carrying the time restriction information for the Quasi-Earth-fixed scenario:since satellites or beams covering the NTN cell may be different in different time periods in the Quasi-Earth-fixed scenario, for targeted measurement collection, the network may configure the UE to perform MDT measurement collection only within a set time according to ephemeris information and the like. For other time, e.g., a time point of switching satellites or beams, since the NTN cell may be covered by a different satellite or beam, the measurement collection behavior of the UE may be stopped.

[0188] The foregoing time restriction information may partially reuse existing information in NTN configuration parameters, such as deadline for measurement collection t-Service of a cell.

[0189] It should be noted that the cell type restriction information in Example 1, the area restriction information in Example 2, and the time restriction information in Example 3 may be arranged and combined according to existing restriction range levels in MDT configuration at different network / tracking area / cell levels.

[0190] Example 4: Protocol signaling plane enhancement and base station processing.

[0191] At a protocol level, the foregoing various restriction information may be carried over a wired network in:(1) interface MDT configuration for Signalling based MDT measurement collection reporting transmitted to a base station via a core network, and / or(2) wired network MDT configuration for Management based MDT measurement collection reporting directly sent by an operator to a base station.

[0192] At a protocol level, the foregoing enhanced information (restriction information) may be carried over an air interface in:(1) air interface MDT configuration for Signalling based MDT measurement collection reporting, and / or,(2) air interface MDT configuration for Management based MDT measurement collection reporting.

[0193] For MDT configuration information carried over the wired network, the MDT configuration information carried over the wired network may be different from that carried over the air interface due to processing of partial content by the base station. For example, for the area restriction information, the base station may receive multiple area ranges for which MDT measurement collection is required to be performed, the base station may configure a UE close to a certain restricted area range to perform possible Logged MDT measurement collection reporting for the restricted area. For another example, for the time restriction information, configuration information for Immediate MDT measurement collection reporting is transmitted between base station nodes as the UE moves, the base station may trigger the UE to perform MDT measurement collection over the air interface only when the UE reaches a start time point for performing MDT measurement collection.

[0194] Example 5: UE reports an MDT measurement collection result.

[0195] Under the foregoing MDT measurement collection restrictions, when reporting the MDT measurement collection result, the UE may carry:

[0196] (1) A type of a serving cell where the UE is located when collecting an MDT result, e.g., a TN cell or an NTN cell.

[0197] (2) An identifier of a serving satellite of the UE when collecting the MDT result.

[0198] (3) Geographic location information of the UE when collecting the MDT result.

[0199] (4) The MDT configuration information received by the UE from a base station side.

[0200] (5) A result calculated by the UE after receiving the MDT configuration information from the base station side, e.g., a reference time, a cell reference point position and the like for each Earth-moving cell independently calculated by the UE according to ephemeris information.

[0201] Content reported by the UE over the air interface for Logged MDT measurement collection reporting is logging entries at periodic different time points or event-triggered logging entries (including multiple logs (periodically) and a single log therein). Therefore, information carried in different logging entries may differ. For example, information carried in logging entries 1 and 2 is relevant information for measurement collection for restricted area A, while the UE changes to restricted area B when collecting logging entry 3, and thus relevant information is carried for restricted area B.

[0202] For Immediate MDT measurement collection reporting, the UE reports in a timely manner, so the base station may associate content reported by the UE with cell information at that time and MDT configuration information, and report to an operator collection node.

[0203] The methods and apparatuses provided in various embodiments of the present disclosure are based on the same application concept. Since principles of the methods and apparatuses for solving problems are similar, for implementations of the apparatuses and methods, reference may be made to each other, and repeated parts will not be elaborated here.
