It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the present disclosure can be implemented in an order other than that illustrated or described herein. Furthermore, the objects distinguished by "first" and "second" are generally of the same type, and do not limit the number of objects. For example, the first object can be one or more.

[0130] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0131] In order to facilitate a clearer understanding of the technical solutions of the various embodiments of the present disclosure, some technical contents related to the various embodiments of the present disclosure are first introduced.

[0132] 1. UE MDT measurement collection and reporting

[0133] The MDT measurement collection and reporting of the UE is divided into two types: immediate MDT measurement collection and reporting and logged MDT measurement collection and reporting. Both types of MDT measurement collection and reporting are configured, managed and issued by the network side.

[0134] After the configuration information of Immediate MDT measurement collection and reporting is sent to the base station node, the radio resource management (Radio Resource Management, RRM) measurement configuration and reporting process is multiplexed on the air interface. The UE receives the relevant MDT measurement configuration information in the radio resource control (Radio Resource Control, RRC) reconfiguration message and reports it to the base station side immediately after performing measurement result collection.

[0135] After the configuration information for Logged MDT measurement collection and reporting is sent to the eNodeB, it is sent to the UE over the air interface using the LoggedMeasurementConfiguration message. The UE only enables measurement logging when it enters the idle or inactive state, and stores the logged results on the UE side. Only when the UE returns to the connected state can it indicate to the network that it has stored the relevant Logged MDT results and then send them to the network.

[0136] From another perspective, the UE's MDT measurement collection and reporting can be divided into two types: signaling-based MDT (Signalling based MDT) measurement collection and reporting and management-based MDT (Management based MDT) measurement collection and reporting.

[0137] Signalling based MDT measurement collection and reporting is used to track the signal status of a single UE. Its MDT configuration is forwarded by the operator through the core network nodes layer by layer. In the New Radio (NR) system, it will be passed to the base station side through core network nodes such as Unified Data Management (UDM) and Access and Mobility Management Function (AMF). For Logged MDT measurement collection and reporting, the base station sends the MDT configuration information to the UE, and the UE subsequently performs measurement collection and reporting; for Immediate MDT measurement collection and reporting, the base station sends part of the information related to UE measurement in the MDT configuration to the UE.

[0138] Management-based MDT measurement collection and reporting is used to collect overall signal conditions within a specific area. The MDT configuration is sent directly by the operator to the relevant base stations. Based on this MDT configuration, the base station can select some or all UEs to perform MDT data measurement collection. For Logged MDT measurement collection and reporting, the base station sends the MDT configuration information to the selected UEs, which then perform measurement collection and report. For Immediate MDT measurement collection and reporting, the base station sends the UE the portion of the MDT configuration related to UE measurements.

[0139] 2. Regional restrictions for MDT configuration

[0140] The MDT configuration includes MDT measurement collection area restriction information for the UE. For Signaling-based MDT measurement collection reports, this area restriction information can be carried in the interface signaling transmitted to the base station via the core network node, as well as in the air interface configuration of Signaling-based logged MDT (signaling-based logged MDT) measurement collection reports. For Management-based MDT measurement collection reports, which are not transmitted via the core network node, this area restriction information can be carried in the air interface configuration of Management-based logged MDT (management-based logged MDT) measurement collection reports.

[0141] The area restrictions configured by MDT include:

[0142] a. Restriction information for the serving cell where the UE is located. For example, the UE is restricted to perform MDT data measurement and collection only when its serving cell is in the PLMN / SNPN / TA / cell list configured by the network.

[0143] b. Restriction information for neighboring cells: For example, when the UE is allowed to perform MDT data measurement and collection, the frequency points and cell identifiers of neighboring cells that the UE can measure and collect are restricted.

[0144] 3. Scenario Classification of Non-Terrestrial Network (NTN) Service Links

[0145] In geostationary (Earth-fixed) scenarios, the satellite maintains the same position relative to the ground, so the beam providing coverage continuously covers the same geographic area. In this scenario, UE mobility and other behaviors are essentially the same between NTN cells and terrestrial network (TN) cells.

[0146] Quasi-geostationary (QGS) scenario: A beam provides coverage for one geographic area for a limited period of time and another geographic area for another limited period of time. In this scenario, the terrestrial NTN area covered by the beam does not move or change during one period of time, and is covered by a different beam during the next period of time.

[0147] Earth-moving scenario: Coverage is provided by beams that slide across the Earth's surface. Because the satellite's orbit is not synchronized with the Earth's rotation, the NTN cell in this scenario is constantly moving.

[0148] 4. Enhanced cell reselection in Quasi-Earth-fixed or Earth-moving scenarios

[0149] To enhance cell reselection in Quasi-Earth-fixed scenarios, a scheme is introduced to broadcast the reference location information of the cell (serving cell or neighboring cell) in the system information. This reference location information is associated with a transmitted epoch time. If the UE has valid location information, the distance between the UE and the reference location of the cell (serving cell and / or neighboring cell) is supported to assist cell reselection. The out-of-service time t-Service of the serving cell is also introduced to enable the UE to trigger measurements of neighboring cells in a timely manner. The out-of-service time of the serving cell is broadcast to the UE via system information.

[0150] For enhanced cell reselection in Earth-moving scenarios, a moving reference point information (movingReferenceLocation) at a certain moment (epoch time) is provided to the terminal. The terminal can estimate the real-time cell reference point location for a period of time in the future based on the ephemeris, epoch time, and movingReferenceLocation information.

[0151] 5. Enhanced reselection from NTN cell to TN cell

[0152] The area of ​​an NTN cell is much larger than that of a TN cell. An NTN cell may have many TN neighboring cells, and these neighboring cells may only be distributed in certain locations of the NTN cell. In locations where there is no TN deployment, in order to avoid unnecessary energy consumption caused by measurements on these frequency points, an enhancement for reselection from NTN cells to TN cells is introduced. The location information of the TN coverage area is broadcasted to the NTN cell, and the UE can decide whether to enable measurement of the corresponding frequency points based on whether there is TN coverage in the surrounding area. The TN coverage area is composed of an area list. The information of each TN coverage area includes: a TN area identifier (such as tn-AreaId-r18), a reference point parameter (such as tn-ReferenceLocation-r18), and a radius parameter (such as tn-DistanceRadius-r18).

[0153] The restriction range in the MDT configuration of the above-mentioned related technologies is divided into three levels: network level (the network includes PLMN and / or SNPN), TA level, and cell level. However, for NTN cells, the geographical scope covered by a single NTN cell is too large, and for different NTN scenarios, the satellites or beams covering the NTN area may change, or the NTN satellite coverage area may move. The MDT configuration using the above-mentioned related technologies is not conducive to operators to collect MDT results in a targeted manner, and the energy consumption overhead of performing MDT measurement collection on the UE may also be wasted.

[0154] For TN scenarios, although the geographical range of TN cells is smaller than that of NTN cells, the MDT configuration schemes of the above-mentioned related technologies are also not conducive to operators collecting MDT results in a targeted manner, and there is also a potential problem of wasted energy consumption when UE performs MDT measurement collection.

[0155] To address the above issues, the present disclosure provides a solution that is applicable to both NTN and TN scenarios. The network side can configure the scope of MDT measurement collection for the terminal as needed, thereby improving the flexibility of MDT measurement collection and reducing unnecessary terminal power consumption.

[0156] FIG1 is a flow chart of an MDT measurement collection method provided in an embodiment of the present disclosure. The method is applied to a terminal. As shown in FIG1 , the method includes the following steps:

[0157] Step 100: Receive MDT configuration information sent by a network device. The MDT configuration information includes restriction information for MDT measurement collection. The restriction information includes at least one of cell type restriction information, area restriction information, and time restriction information.

[0158] Step 101: Perform MDT measurement collection based on MDT configuration information.

[0159] Specifically, in the present disclosure, a network device (eg, a base station) may carry MDT measurement collection restriction information in the MDT configuration information sent to a terminal, so as to configure the scope of MDT measurement collection for the terminal in a targeted manner.

[0160] In this disclosure, MDT measurement collection refers to: on the terminal side, the collection and recording of available terminal measurement results (measurement or measurement result), measurement configuration, measurement-related information, etc. for MDT purposes; and / or, on the terminal side, the performance of terminal measurements solely for MDT purposes, and the collection and recording of relevant measurement results, measurement configuration, measurement-related information, etc.

[0161] In some embodiments, the MDT configuration information may be NTN-related MDT configuration information.

[0162] In some embodiments, the cell type restriction information includes one or more of the following indication information:

[0163] (1) First indication information: The first indication information is used to instruct the terminal to measure and collect MDT data of TN cells and / or NTN cells.

[0164] For example, the network device carries first indication information in the MDT configuration information sent to the terminal, where the first indication information instructs the terminal to collect only measurement results of TN cells, or instructs the terminal to collect only measurement results of NTN cells, or instructs the terminal to collect measurement results of both NTN cells and TN cells. The terminal may perform MDT measurement collection for the restricted cell types according to the indication of the first indication information.

[0165] (2) Second indication information: The second indication information is used to indicate whether the terminal is allowed to measure and collect MDT data of the NTN cell when the terminal resides in or is connected to the TN cell.

[0166] For example, the network device may include second indication information in the MDT configuration information sent to the terminal. The second indication information indicates whether the terminal is allowed to collect measurement results on NTN frequencies or NTN cells when the terminal is residing in or connected to a TN cell. When the terminal is residing in or connected to a TN cell, the terminal may determine whether to perform NTN-related MDT measurement collection based on the second indication information.

[0167] (3) Third indication information: The third indication information is used to indicate whether the terminal is allowed to measure and collect MDT data of the TN cell when the terminal resides in or is connected to the NTN cell.

[0168] For example, the network device carries third indication information in the MDT configuration information sent to the terminal. The third indication information indicates whether the terminal is allowed to collect measurement results on TN frequencies or TN cells when the terminal is residing in or connected to an NTN cell. When the terminal is residing in or connected to the NTN cell, the terminal can determine whether to perform TN-related MDT measurement collection based on the third indication information.

[0169] Indicating the cell type restriction information for MDT measurement collection by one or more of the first indication information, the second indication information, and the third indication information can meet various targeted MDT measurement collection requirements and improve the flexibility of MDT measurement collection.

[0170] In some embodiments, the region restriction information includes one or more of the following:

[0171] (1) TN area identifier: The TN area identifier is used to identify the TN coverage area.

[0172] In some implementations, the area for MDT measurement collection can be indicated in combination with the "information of the TN coverage area broadcast by the network for the NTN cell" mentioned in the relevant technology. For example, when the network broadcasts the information of the TN coverage area for the NTN cell, if the area for MDT measurement collection includes the TN coverage area, the network device can directly carry the TN area identifier corresponding to the area for MDT measurement collection in the MDT configuration information. The terminal can obtain the specific area range based on the TN area identifier carried in the MDT configuration information and the information of the TN coverage area broadcast by the network.

[0173] (2) Restricted area list: The restricted area list is a list of areas where MDT measurements are collected.

[0174] 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 the reference point location, and the radius parameter is used to determine the radius of the area to be restricted. It can be a radius value or a distance threshold. The reference point location combined with the radius can determine the specific area range.

[0175] For example, for NTN cells, it can be used to collect MDT data for part of the geographical location range within the NTN cell, avoiding performing MDT collection on unnecessary geographical locations and saving terminal energy consumption; for TN cells, it can include MDT data collection for the geographical range corresponding to multiple TN cells, without having to send the cell identifiers of these cells, saving configuration signaling.

[0176] In some embodiments, each entry in the restricted area list includes a logical identifier (ID) that maps 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-square grid, a 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 the protocol or instructed to the terminal by the network side.

[0177] For example, both the terminal and the network device divide the NTN cell according to the nine-square grid mapping rule. An NTN cell can be divided into 9 areas, each area corresponds to a logical identifier. The network device can instruct the terminal to perform MDT measurements only for one or some areas in the NTN cell, such as performing MDT measurement collection only for the area with the mapped logical identifier 0.

[0178] (3) Restricted frequency point information: The restricted frequency point information is used to indicate which frequency points the terminal should perform MDT measurement collection on.

[0179] Since TN and NTN are basically deployed at different frequencies, in some implementations, frequency information may be restricted to indicate whether to perform MDT measurement collection on a TN cell or an NTN cell.

[0180] In some embodiments, the restricted frequency information is restricted frequency information shared by MDT measurement collection for the serving cell and MDT measurement collection for the neighboring cell, that is, the MDT measurement collection of the serving cell and the neighboring cell of the terminal share the same set of restricted frequency information; or, the restricted frequency information includes restricted frequency information configured for MDT measurement collection for the serving cell and / or restricted frequency information configured for MDT measurement collection for the neighboring cell, that is, the MDT measurement collection of the serving cell and the neighboring cell of the terminal can be separately configured or not configured with their own restricted frequency information.

[0181] The restricted area range for MDT measurement collection is indicated by one or more combinations of TN area identifiers, restricted area lists, and restricted frequency information, thereby improving the flexibility of MDT configuration and saving signaling overhead as much as possible.

[0182] In some embodiments, the time limit information includes any of the following:

[0183] (1) Measurement collection deadline information: The measurement collection deadline information is used to indicate the deadline point for the terminal to perform MDT measurement collection.

[0184] In some implementations, for NTN-related MDT measurement collection, the measurement collection cutoff time point may be the time when the NTN cell ends covering a certain area, as calculated by the network.

[0185] In the case where the MDT configuration information only indicates the cutoff time information for measurement collection, the terminal may determine the starting time point for the terminal to perform MDT measurement collection through other methods. For example, the protocol stipulates that the starting time point for the terminal to perform MDT measurement collection is when the terminal receives the MDT configuration information, or when certain conditions are met (for example, when the terminal enters an idle state or an inactive state, or when the terminal enters a cell configured by the network, or when the terminal enters an area restricted in the MDT configuration information, etc.).

[0186] (2) Measurement collection start time information and measurement collection end time information: The measurement start time information is used to indicate the start time point of the terminal performing MDT measurement collection.

[0187] In some implementations, for NTN-related MDT measurement collection, the measurement start time point may be the time when the NTN cell covers a certain area as calculated by the network; the measurement collection end time point may be the time when the NTN cell ends covering a certain area as calculated by the network.

[0188] (3) Measurement collection start time information and measurement collection duration information: The measurement duration information is used to indicate the duration of the MDT measurement collection performed by the terminal.

[0189] In some implementations, for NTN-related MDT measurement collection, the start time point of the measurement collection may be the moment when the NTN cell covers a certain area, as calculated by the network; the end time point calculated based on the measurement duration information may be the moment when the NTN cell ends covering a certain area, as calculated by the network.

[0190] In some embodiments, for the Earth moving scenario, since the location of the NTN cell is constantly changing in this scenario, in order to avoid unnecessary power consumption, the network can configure the terminal to perform MDT measurement collection only within a set time based on ephemeris information, etc. (by carrying time limit information in the above-mentioned MDT configuration information). For other times, since the NTN cell that the terminal is required to measure has not yet covered the area where the network wants to perform MDT measurement collection, the terminal's measurement collection behavior can be turned off.

[0191] In some embodiments, for the Quasi-Earth-fixed scenario, since the satellites or beams covering the NTN cell in different time periods in this scenario may be different, in order to perform targeted measurements, the network can configure the terminal to perform MDT measurement collection only within the set time based on ephemeris information, etc. (by carrying time limit information in the above-mentioned MDT configuration information). For other times, such as the time point when the satellite or beam is changed, since the NTN cell may be covered by different satellites or beams, the terminal's measurement collection behavior can be turned off.

[0192] The present disclosure does not limit the specific indication method or time format of the above-mentioned time limit information. Existing parameter information can be partially reused, or it can be indicated through newly defined time parameters, etc. For example, the time format relative to t-Service (the out-of-service time of the serving cell) can be used to indicate the start time point or the end time point of measurement collection, or the time format of epoch time can be used to save signaling, or the time format of Coordinated Universal Time (UTC) can be directly configured, etc.

[0193] By configuring one or more of the measurement collection start time information, measurement collection end time information, and measurement collection duration information, the terminal can be more flexibly instructed to perform the MDT measurement collection time period, thereby avoiding unnecessary continuous measurement collection behavior that wastes terminal power.

[0194] In some embodiments, the restriction information is one or more sets, each set of restriction information is associated with one or more cells, or each set of restriction information is associated with one or more tracking areas, or each set of restriction information is associated with one or more networks.

[0195] 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. A set of area restriction information and a set of time restriction information are configured for each cell or cell group, or a set of cell type restriction information and a set of area restriction information are configured for each network or network group (the network includes PLMN and / or SNPN), or a set of time restriction information is configured for each TA or TA list, and so on.

[0196] In the present disclosure, the cell type restriction information, the area restriction information, and the time restriction information can be arranged and combined according to the existing restriction range levels in the MDT configuration at different network / tracking area / cell levels, and the terminal can perform MDT measurement collection based on the combined restriction information.

[0197] By configuring one or more sets of MDT measurement collection restriction information and associating them with cells, tracking areas or networks, different MDT measurement collection requirements for different cells, tracking areas or networks can be met, thereby improving the flexibility of MDT measurement collection.

[0198] In the embodiment of the present disclosure, the area restriction information and / or time restriction information carried in the MDT configuration information may partially reuse parameter information in the existing NTN / TN related configuration, or the network may send newly defined restriction information to the terminal, which is not limited in the present disclosure.

[0199] The MDT measurement collection method provided in the embodiments of the present disclosure can specifically configure the scope of MDT measurement collection for a terminal by carrying at least one of cell type restriction information, area restriction information, and time restriction information for MDT measurement collection in MDT configuration information, thereby improving the flexibility of MDT measurement collection and reducing unnecessary terminal power consumption.

[0200] In some embodiments, the method further comprises:

[0201] Report an MDT measurement collection report. The MDT measurement collection report contains one or more of the following:

[0202] (1) The type of the terminal's serving cell when collecting MDT results.

[0203] For example, after performing MDT measurement based on the MDT configuration information, the terminal reports an 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. For example, when the terminal collects the MDT result, the serving cell of the terminal is a TN cell or an NTN cell.

[0204] (2) The satellite identifier of the terminal's serving satellite when collecting MDT results.

[0205] For example, after the terminal performs MDT measurement based on the MDT configuration information, it reports an MDT measurement collection report. The MDT measurement collection report includes the MDT result and also carries the satellite identifier of the terminal's serving satellite when the terminal collects the MDT result. The satellite identifier is used to indicate which satellite provided service to the terminal when the terminal collected the MDT result.

[0206] (3) The geographical location information of the terminal when collecting MDT results.

[0207] For example, after performing MDT measurement based on MDT configuration information, the terminal reports an MDT measurement collection report. The MDT measurement collection report includes the MDT result and also carries the geographical location information of the terminal when the terminal collects the MDT result, so that the network can understand the location of the terminal when the MDT result is collected.

[0208] (4)MDT configuration information.

[0209] For example, after performing MDT measurement based on MDT configuration information, the terminal reports an MDT measurement collection report. The MDT measurement collection report includes an MDT result and also carries corresponding MDT configuration information to indicate the MDT configuration information based on which the MDT result is obtained.

[0210] Taking Logged MDT measurement collection and reporting as an example, after the configuration information for Logged MDT measurement collection and reporting is delivered to the terminal, the terminal starts recording measurements only after entering the idle or inactive state, and stores the recorded results on the terminal side. Only after the terminal returns to the connected state can the terminal report its stored Logged MDT results to the network side. In this case, the terminal can include MDT configuration information in the MDT measurement collection report. The MDT configuration information is associated with the Logged MDT results, allowing the network side to understand the MDT configuration information used to perform the MDT measurements for each Logged MDT result.

[0211] For Immediate MDT measurement collection and reporting, the terminal side reports in a timely manner. Therefore, the network side can associate the terminal report content with the current cell information and MDT configuration information and report it to the operator's collection node.

[0212] (5) The result calculated by the terminal based on the MDT configuration information.

[0213] For example, after receiving the MDT configuration information from the network side, the terminal calculates the reference time and cell reference point position of each Earth-moving cell by itself through ephemeris information, etc. When reporting the MDT measurement collection report, the terminal carries these calculated results in the MDT measurement collection report and reports them together.

[0214] By reporting various report-related information when reporting the MDT measurement collection 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 the MDT measurement collection report analysis.

[0215] FIG2 is a flow chart of an MDT configuration method provided in an embodiment of the present disclosure. The method is applied to a network device (e.g., a base station). As shown in FIG2 , the method includes the following steps:

[0216] Step 200: Send MDT configuration information to the terminal. The MDT configuration information includes restriction information for MDT measurement collection. The restriction information includes at least one of cell type restriction information, area restriction information, and time restriction information.

[0217] Specifically, in the present disclosure, the network device may carry MDT measurement collection restriction information in the MDT configuration information sent to the terminal, so as to configure the scope of the MDT measurement collection of the terminal in a targeted manner.

[0218] In some embodiments, the MDT configuration information may be NTN-related MDT configuration information.

[0219] In some embodiments, the cell type restriction information includes one or more of the following indication information:

[0220] (1) First indication information: The first indication information is used to instruct the terminal to measure and collect MDT data of TN cells and / or NTN cells.

[0221] For example, the network device carries first indication information in the MDT configuration information sent to the terminal, where the first indication information instructs the terminal to collect only measurement results of TN cells, or instructs the terminal to collect only measurement results of NTN cells, or instructs the terminal to collect measurement results of both NTN cells and TN cells. The terminal may perform MDT measurement collection for the restricted cell types according to the indication of the first indication information.

[0222] (2) Second indication information: The second indication information is used to indicate whether the terminal is allowed to measure and collect MDT data of the NTN cell when the terminal resides in or is connected to the TN cell.

[0223] For example, the network device may include second indication information in the MDT configuration information sent to the terminal. The second indication information indicates whether the terminal is allowed to collect measurement results on NTN frequencies or NTN cells when the terminal is residing in or connected to a TN cell. When the terminal is residing in or connected to a TN cell, the terminal may determine whether to perform NTN-related MDT measurement collection based on the second indication information.

[0224] (3) Third indication information: The third indication information is used to indicate whether the terminal is allowed to measure and collect MDT data of the TN cell when the terminal resides in or is connected to the NTN cell.

[0225] For example, the network device carries third indication information in the MDT configuration information sent to the terminal. The third indication information indicates whether the terminal is allowed to collect measurement results on TN frequencies or TN cells when the terminal is residing in or connected to an NTN cell. When the terminal is residing in or connected to the NTN cell, the terminal can determine whether to perform TN-related MDT measurement collection based on the third indication information.

[0226] Indicating the cell type restriction information for MDT measurement collection by one or more of the first indication information, the second indication information, and the third indication information can meet various targeted MDT measurement collection requirements and improve the flexibility of MDT measurement collection.

[0227] In some embodiments, the region restriction information includes one or more of the following:

[0228] (1) TN area identifier: The TN area identifier is used to identify the TN coverage area.

[0229] In some implementations, the area for MDT measurement collection can be indicated in combination with the "information of the TN coverage area broadcast by the network for the NTN cell" mentioned in the relevant technology. For example, when the network broadcasts the information of the TN coverage area for the NTN cell, if the area for MDT measurement collection includes the TN coverage area, the network device can directly carry the TN area identifier corresponding to the area for MDT measurement collection in the MDT configuration information. The terminal can obtain the specific area range based on the TN area identifier carried in the MDT configuration information and the information of the TN coverage area broadcast by the network.

[0230] (2) Restricted area list: The restricted area list is a list of areas where MDT measurements are collected.

[0231] 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 the reference point location, and the radius parameter is used to determine the radius of the area to be restricted. It can be a radius value or a distance threshold. The reference point location combined with the radius can determine the specific area range.

[0232] For example, for NTN cells, it can be used to collect MDT data for part of the geographical location range within the NTN cell, avoiding performing MDT collection on unnecessary geographical locations and saving terminal energy consumption; for TN cells, it can include MDT data collection for the geographical range corresponding to multiple TN cells, without having to send the cell identifiers of these cells, saving configuration signaling.

[0233] In some embodiments, each entry in the restricted area list includes a logical identifier that maps to a fixed area. The fixed area is mapped using a certain mapping rule, such as a nine-square grid, a base station's three-sector angle, or the like. The terminal and the network device follow the same mapping rule, which can be agreed upon in the protocol or instructed to the terminal by the network.

[0234] For example, both the terminal and the network device divide the NTN cell according to the nine-square grid mapping rule. An NTN cell can be divided into 9 areas, each area corresponds to a logical identifier. The network device can instruct the terminal to perform MDT measurements only for one or some areas in the NTN cell, such as performing MDT measurement collection only for the area with the mapped logical identifier 0.

[0235] (3) Restricted frequency point information: The restricted frequency point information is used to indicate which frequency points the terminal should perform MDT measurement collection on.

[0236] Since TN and NTN are basically deployed at different frequencies, in some implementations, frequency information may be restricted to indicate whether to perform MDT measurement collection on a TN cell or an NTN cell.

[0237] In some embodiments, the restricted frequency information is restricted frequency information shared by MDT measurement collection for the serving cell and MDT measurement collection for the neighboring cell, that is, the MDT measurement collection of the serving cell and the neighboring cell of the terminal share the same set of restricted frequency information; or, the restricted frequency information includes restricted frequency information configured for MDT measurement collection for the serving cell and / or restricted frequency information configured for MDT measurement collection for the neighboring cell, that is, the MDT measurement collection of the serving cell and the neighboring cell of the terminal can be separately configured or not configured with their own restricted frequency information.

[0238] The restricted area range for MDT measurement collection is indicated by one or more combinations of TN area identifiers, restricted area lists, and restricted frequency information, thereby improving the flexibility of MDT configuration and saving signaling overhead as much as possible.

[0239] In some embodiments, the time limit information includes any of the following:

[0240] (1) Measurement collection deadline information: The measurement collection deadline information is used to indicate the deadline point for the terminal to perform MDT measurement collection.

[0241] In some implementations, for NTN-related MDT measurement collection, the measurement collection cutoff time point may be the time when the NTN cell ends covering a certain area, as calculated by the network.

[0242] In the case where the MDT configuration information only indicates the cutoff time information for measurement collection, the terminal may determine the starting time point for the terminal to perform MDT measurement collection through other methods. For example, the protocol stipulates that the starting time point for the terminal to perform MDT measurement collection is when the terminal receives the MDT configuration information, or when certain conditions are met (for example, when the terminal enters an idle state or an inactive state, or when the terminal enters a cell configured by the network, or when the terminal enters an area restricted in the MDT configuration information, etc.).

[0243] (2) Measurement collection start time information and measurement collection end time information: The measurement collection start time information is used to indicate the start time point of the terminal performing MDT measurement collection.

[0244] In some implementations, for NTN-related MDT measurement collection, the start time point of measurement collection may be the time when the NTN cell covers a certain area as calculated by the network; the end time point of measurement collection may be the time when the NTN cell ends covering a certain area as calculated by the network.

[0245] (3) Measurement collection start time information and measurement collection duration information: The measurement collection duration information is used to indicate the duration of the terminal performing MDT measurement collection.

[0246] In some implementations, for NTN-related MDT measurement collection, the start time point of the measurement collection may be the moment when the NTN cell covers a certain area, as calculated by the network; the end time point calculated based on the duration information of the measurement collection may be the moment when the NTN cell ends covering a certain area, as calculated by the network.

[0247] In some embodiments, for the Earth moving scenario, since the location of the NTN cell is constantly changing in this scenario, in order to avoid unnecessary power consumption, the network can configure the terminal to perform MDT measurement collection only within a set time based on ephemeris information, etc. (by carrying time limit information in the above-mentioned MDT configuration information). For other times, since the NTN cell that the terminal is required to measure has not yet covered the area where the network wants to perform MDT measurement collection, the terminal's measurement collection behavior can be turned off.

[0248] In some embodiments, for the Quasi-Earth-fixed scenario, since the satellites or beams covering the NTN cell in different time periods in this scenario may be different, in order to perform targeted measurements, the network can configure the terminal to perform MDT measurement collection only within the set time based on ephemeris information, etc. (by carrying time limit information in the above-mentioned MDT configuration information). For other times, such as the time point when the satellite or beam is changed, since the NTN cell may be covered by different satellites or beams, the terminal's measurement collection behavior can be turned off.

[0249] The present disclosure does not limit the specific indication method or time format of the above-mentioned time limit information. Existing parameter information can be partially reused, or it can be indicated through newly defined time parameters, etc. For example, the time format relative to t-Service (the out-of-service time of the serving cell) can be used to indicate the start time point or the end time point of measurement collection, or the time format of epoch time can be used to save signaling, or the time format of UTC time can be directly used, etc.

[0250] By configuring one or more of the measurement collection start time information, measurement collection end time information, and measurement collection duration information, the terminal can be more flexibly instructed to perform the MDT measurement collection time period, thereby avoiding unnecessary continuous measurement collection behavior that wastes terminal power.

[0251] In some embodiments, the restriction information is one or more sets, each set of restriction information is associated with one or more cells, or each set of restriction information is associated with one or more tracking areas, or each set of restriction information is associated with one or more networks.

[0252] 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. A set of area restriction information and a set of time restriction information are configured for each cell or cell group, or a set of cell type restriction information and a set of area restriction information are configured for each network or network group (the network includes PLMN and / or SNPN), or a set of time restriction information is configured for each TA or TA list, and so on.

[0253] By configuring one or more sets of MDT measurement collection restriction information and associating them with cells, tracking areas or networks, different MDT measurement collection requirements for different cells, tracking areas or networks can be met, thereby improving the flexibility of MDT measurement collection.

[0254] In the embodiment of the present disclosure, the area restriction information and / or time restriction information carried in the MDT configuration information may partially reuse parameter information in the existing NTN / TN related configuration, or the network may send newly defined restriction information to the terminal, which is not limited in the present disclosure.

[0255] The MDT configuration method provided in the embodiments of the present disclosure can specifically configure the scope of MDT measurement collection for a terminal by carrying at least one of cell type restriction information, area restriction information, and time restriction information for MDT measurement collection in MDT configuration information, thereby improving the flexibility of MDT measurement collection and reducing unnecessary terminal power consumption.

[0256] In some embodiments, the method further comprises:

[0257] Receive an MDT measurement collection report sent by a terminal. The MDT measurement collection report includes one or more of the following:

[0258] (1) The type of the terminal's serving cell when collecting MDT results.

[0259] For example, after performing MDT measurement based on the MDT configuration information, the terminal reports an 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. For example, when the terminal collects the MDT result, the serving cell of the terminal is a TN cell or an NTN cell.

[0260] (2) The satellite identifier of the terminal's serving satellite when collecting MDT results.

[0261] For example, after the terminal performs MDT measurement based on the MDT configuration information, it reports an MDT measurement collection report. The MDT measurement collection report includes the MDT result and also carries the satellite identifier of the terminal's serving satellite when the terminal collects the MDT result. The satellite identifier is used to indicate which satellite provided service to the terminal when the terminal collected the MDT result.

[0262] (3) The geographical location information of the terminal when collecting MDT results.

[0263] For example, after performing MDT measurement based on MDT configuration information, the terminal reports an MDT measurement collection report. The MDT measurement collection report includes the MDT result and also carries the geographical location information of the terminal when the terminal collects the MDT result, so that the network can understand the location of the terminal when the MDT result is collected.

[0264] (4)MDT configuration information.

[0265] For example, after performing MDT measurement based on MDT configuration information, the terminal reports an MDT measurement collection report. The MDT measurement collection report includes an MDT result and also carries corresponding MDT configuration information to indicate the MDT configuration information based on which the MDT result is obtained.

[0266] Taking Logged MDT measurement collection and reporting as an example, after the configuration information for Logged MDT measurement collection and reporting is delivered to the terminal, the terminal starts recording measurements only after entering the idle or inactive state, and stores the recorded results on the terminal side. Only after the terminal returns to the connected state can the terminal report its stored Logged MDT results to the network side. In this case, the terminal can include MDT configuration information in the MDT measurement collection report. The MDT configuration information is associated with the Logged MDT results, allowing the network side to understand the MDT configuration information used to perform the MDT measurements for each Logged MDT result.

[0267] For Immediate MDT measurement collection and reporting, the terminal side reports in a timely manner. Therefore, the network side can associate the terminal report content with the current cell information and MDT configuration information and report it to the operator's collection node.

[0268] (5) The result calculated by the terminal based on the MDT configuration information.

[0269] For example, after receiving the MDT configuration information from the network side, the terminal calculates the reference time and cell reference point position of each Earth-moving cell by itself through ephemeris information, etc. When reporting the MDT measurement collection report, the terminal carries these calculated results in the MDT measurement collection report and reports them together.

[0270] By reporting various report-related information when reporting the MDT measurement collection 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 the MDT measurement collection report analysis.

[0271] The methods provided in the various embodiments of the present disclosure are based on the same application concept, so the implementation of each method can refer to each other, and the repeated parts will not be repeated.

[0272] The following describes the methods provided in the above embodiments of the present disclosure through examples of specific application scenarios.

[0273] Example 1: Cell type restriction information.

[0274] In the MDT configuration, NTN cell and / or TN cell measurement collection indication can be carried. The indication method can be one or more of the following:

[0275] (1) Instruct to collect only the measurement results of TN cells or only the measurement results of NTN cells, or instruct to collect the measurement results of both NTN cells and TN cells at the same time.

[0276] (2) Indicates whether to allow collection of measurement results on NTN frequencies or NTN cells when the UE is camped on or connected to a TN cell.

[0277] (3) Indicates whether to allow collection of measurement results on TN frequencies or TN cells when the UE is camped on or connected to an NTN cell.

[0278] Example 2: Regional restriction information.

[0279] In the MDT configuration, location area-related restriction parameters can be carried. The carrying method can be one or more of the following:

[0280] (1) For cells that broadcast TN coverage area information, the area restriction information in the MDT configuration can carry the TN area identifier. This approach leverages the existing measurement area range for TN cell reselection configured for TN coverage areas in the NTN, allowing MDT measurement collection to be performed primarily within the TN coverage area.

[0281] (2) The area restriction information in the MDT configuration can carry a list of restricted areas:

[0282] i. Each entry in the list contains a reference point coordinate + radius or threshold.

[0283] In this way, regardless of the cell type for which MDT measurement collection is performed, a restricted area can be set. For NTN cells, this can be used to collect MDT data for a portion of the geographic location within the NTN cell, avoiding unnecessary MDT collection at the location and saving UE energy consumption. For TN cells, MDT data collection can be included in the geographic range corresponding to multiple TN cells without having to send the cell identifiers of these cells, saving configuration signaling.

[0284] ii. Each entry in the list contains a logical ID that maps to a fixed area.

[0285] In this approach, within each NTN cell, a logical ID can be mapped to a fixed area. This fixed area is mapped using a mapping rule, such as a nine-square grid or a three-sector angle for a base station. Both the UE and the base station divide the NTN cell according to the same mapping rule. The mapping rule can be a default between the UE and the network, or issued by the network. For example, the network configures the UE to divide the NTN cell according to the nine-square grid rule and performs MDT measurement collection only for the area where the mapping ID = 0.

[0286] (3) The area range in the MDT configuration can carry the restricted frequency information required to perform MDT measurement collection. In this way, since TN and NTN are basically deployed at different frequency points, carrying the relevant frequency information can clearly indicate that MDT measurement collection should be performed on different types of frequency points of TN or NTN. The restricted frequency information can limit the UE's serving cell and / or limit the range of neighboring cell MDT data measurement collection performed by the UE:

[0287] i. The UE's serving cell and neighboring cell MDT measurement collection share the same restricted frequency information.

[0288] ii. The UE's serving cell and neighboring cell MDT measurement collection can be configured or not configured with their own restricted frequency information separately.

[0289] The above-mentioned area restriction information may partially reuse the existing information in the NTN configuration parameters, such as the location reference point movingReferenceLocation of the Earth moving scenario of this cell.

[0290] Example 3: Time limit information.

[0291] In the MDT configuration, time limit information can be carried in one or more of the following ways:

[0292] (1) The carried time limit information includes the measurement collection cutoff time information. The starting time point of the UE's MDT measurement collection time is when the MDT-related configuration is received, or when certain conditions are met (such as entering the idle state or inactive state, entering a cell configured by the network, or entering the location restriction area in Example 2, etc.), and the end time point is the time point indicated by the measurement collection cutoff time information.

[0293] (2) The time limit information carried includes the start time information of measurement collection + the end time information of measurement collection, or the start time information of measurement collection + the duration information of measurement collection. The start time point of measurement collection can be the moment when the NTN cell covers a certain area as calculated by the network, that is, the start time point of MDT measurement collection; the end time point of measurement collection, or the end time point calculated based on the duration information of measurement collection, can be the moment when the NTN cell ends covering a certain area as calculated by the network, that is, the end time point of MDT measurement collection.

[0294] For the Earth moving scenario, carry time limit information:

[0295] Due to the Earth Moving scenario, the location of the NTN cell is constantly changing. Therefore, to avoid unnecessary power consumption, the network can configure the UE to perform MDT measurement collection only during the set time based on ephemeris information. At other times, since the NTN cell that the UE is required to measure has not yet covered the area where the network wants to perform MDT measurement collection, its measurement collection behavior can be turned off.

[0296] For the Quasi-Earth-fixed scenario, carry time limit information:

[0297] Due to the Quasi-Earth-fixed scenario, the satellites or beams covering the NTN cell may be different in different time periods. Therefore, in order to collect targeted measurements, the network can configure the UE to perform MDT measurement collection only during the set time based on ephemeris information. For other times, such as the time point when the satellite / beam is changed, the measurement collection behavior can be disabled because the NTN cell may be covered by different satellites / beams.

[0298] The above time limit information may partially reuse the existing information in the NTN configuration parameters, such as the cutoff time t-Service for measurement collection in the current cell.

[0299] 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 can be arranged and combined according to the existing restriction range levels in the MDT configuration at different network / tracking area / cell levels.

[0300] Example 4: Protocol signaling plane enhancement and base station processing.

[0301] At the protocol level, the aforementioned restriction information can be carried in the following formats on the wired network:

[0302] (1) The interface MDT configuration for Signaling-based MDT measurement collection and reporting transmitted to the base station via the core network, and / or

[0303] (2) The wired network MDT configuration reported by the operator in the Management-based MDT measurement collection directly sent to the base station.

[0304] The above-mentioned enhanced information (restriction information), at the protocol level, can be carried in the air interface:

[0305] (1) Signaling based MDT measurement collection and reporting in the air interface MDT configuration, and / or,

[0306] (2) Management based MDT measurement collection and reporting in the air interface MDT configuration.

[0307] The MDT configuration information carried by the wired network may differ between the MDT configuration information carried by the wired network and the air interface due to base station processing of some content. For example, for area restriction information, the base station may have received multiple area ranges for MDT measurement collection. The base station can configure UEs approaching a restricted area to perform Logged MDT measurement collection and reporting for that restricted area. For another example, for time restriction information, the configuration information for Immediate MDT measurement collection and reporting is transmitted between base station nodes as the UE moves. The base station can trigger the UE to perform MDT measurement collection over the air interface only when the UE reaches the starting time point for MDT measurement collection.

[0308] Example 5: UE reports MDT measurement collection results.

[0309] To address the above MDT measurement collection restrictions, when reporting MDT measurement collection results, the UE can carry:

[0310] (1) The type of the serving cell in which the UE is located when collecting MDT results, such as a TN cell or an NTN cell.

[0311] (2) The identifier of the UE's serving satellite when the UE collects MDT results.

[0312] (3) The geographical location information of the UE when the UE collects the MDT results.

[0313] (4) The UE receives the MDT configuration information from the base station.

[0314] (5) After receiving the MDT configuration information from the base station, the UE calculates the results, for example, the reference time and cell reference point position for each Earth-moving cell calculated by the UE itself using ephemeris information.

[0315] The content of the Logged MDT measurement collection and reporting on the UE's air interface is a log entry for different periodic time points, or a log entry triggered by an event (including multiple records (periodic) and single records). Therefore, the information carried in different log entries may be different. For example, the information carried in log entries 1 and 2 is related to the measurement collection of restricted area A, while when the UE collects log entry 3, it changes to restricted area B, and carries relevant information for restricted area B.

[0316] For Immediate MDT measurement collection and reporting, the UE side reports in a timely manner. Therefore, the base station can associate the UE report content with the current cell information and MDT configuration information and report it to the operator's collection node.

[0317] The methods and devices provided in the various embodiments of the present disclosure are based on the same application concept.
