Description

Information processing method, device, terminal and network equipment

This disclosure claims priority to the Chinese patent application filed on April 3, 2024, with application number 202410403506.0 and application name “Information Processing Method, Device, Terminal and Network Equipment”, the entire contents of which are incorporated herein by reference.

Technical Field

The present disclosure relates to the field of communication technologies, and in particular to an information processing method, apparatus, terminal, and network equipment.

Background Art

In transmission networks (TNs), terminals, or user equipment (UE), collect and report Self-Organizing Network (SON) and Minimization of Drive-Test (MDT) data for fixed-location network equipment (such as base stations) and the cells within them. In non-terrestrial networks (NTNs), however, if the service link is quasi-Earth-fixed or earth-moving, satellites covering the same location and the cells within their coverage may be located in different or mobile locations. Therefore, in NTNs, if terminals report SON and/or MDT information according to TNs, the network may be unable to determine which satellite or cell to adjust. Currently, there is no solution for terminals to perform SON and/or MDT reporting in NTNs.

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.

The following is an introduction to the relevant technologies involved in this disclosure:

1. UE MDT measurement record reporting

UE MDT measurement record reporting is divided into two types: Immediate MDT and Logged MDT. Both types of measurement record reporting are configured, managed, and issued by the network device side. Specifically:

Immediate MDT: After the configuration information is sent to the base station node, the radio resource management (RRM) measurement configuration and reporting process is reused on the air interface. The UE receives the relevant MDT measurement configuration information in the radio resource management (RRC) reconfiguration message and reports the measurement results to the network equipment immediately after performing the measurement collection.

Logged MDT: After configuration information is delivered to the base station, it is sent to the UE over the air interface using a Logged Measurement Configuration message. The UE only starts logging measurements when it enters the IDLE or INACTIVE states, and the results are stored on the UE. Once the UE returns to the CONNECTED state, it can indicate to the network device that it has stored the relevant Logged MDT results, which it then reports to the network device.

From another perspective, UE MDT measurement record reporting can be divided into two types: signaling-based MDT and management-based MDT. Specifically:

Signaling-based MDT: Used to track the signal status of a single UE. Its MDT configuration is forwarded by the operator through core network nodes. In the NR system, it is transmitted to the base station through core network nodes such as the Unified Data Management (UDM) network element and the Access and Mobility Management Function (AMF) network element. For logged MDT, the base station sends the MDT configuration information to the UE, which then collects and reports the measurement results. For immediate MDT, the base station sends the UE the portion of the MDT configuration related to UE measurements.

Management-based MDT: 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 the MDT configuration, the base station can select some or all UEs to collect relevant MDT measurement data. For logged MDT, the base station sends the MDT configuration information to the selected UEs, which then perform measurements, receive data, and report them. For immediate MDT, the base station sends the UE the portion of the MDT configuration related to UE measurements.

The UE's MDT measurement record reporting is generally performed by collecting existing measurement results on the UE side. For example, the UE can directly collect the measurement results of UE cell selection and/or reselection, and record and store these results for subsequent reporting; or the UE can perform additional measurements separately, and record and store these results for subsequent reporting.

The UE reports the Logged MDT record content, which is not real-time. It needs to send a result available indication to the network device later. The UE will report the relevant record content only after the network device requests it.

After the network device receives the Logged MDT record content reported by the UE, it will send it to OAM, such as the OAM trace collection entity (TCE), as input data for subsequent big data processing, refinement, and optimization.

2. UE SON record reporting

UE SON record reporting includes:

Connection Establishment/Resume Failure (CEF) Report: Records information about RRC establishment failure/resume failure on the UE side, and subsequently sends a result available indication to the network. Reports relevant record content upon receiving a request from the network side.

Radio Link Failure/Handover Failure (RLF/HOF) reporting: records radio link failure/handover failure information on the UE side, and subsequently sends a result available indication to the network. It reports the relevant record content upon receiving a request from the network side.

Random Access (RA) report: records the failure/success of random access on the UE side and reports the relevant record content after receiving a request from the network side;

Successful Handover Report/Successful PSCell (Addition/change) Report (SHR/SPR): Records critical failures of successful handover/addition or change of a Primary or Secondary Cell (PSCell) on the UE side, and subsequently sends a result available indication to the network. Reports the relevant record content upon receiving a request from the network device.

Mobility History Information (MHI): records the information of cell changes on the UE side, and subsequently sends an indication of the available results to the network device, and reports the relevant record content after receiving a request from the network device side.

After receiving the SON record report from the UE, the network equipment side will send the corresponding record content to the cell related to the failure, and perform optimization such as parameter adjustment in the cell.

The UE reports the SON record content not in real time, and needs to wait for the network device to request it before reporting the relevant record content.

After receiving the SON-related record content reported by the UE, the network device can send it to the network device where the UE is located when the record is executed (for example, the base station where the cell where the UE has an RLF is located), or the source network device and/or target network device (for example, the base station where the source cell and/or target cell where the UE has a handover failure, critical failure successful handover, etc. is located), for performing parameter optimization and adjustment on the cells and/or base stations where these UEs have connection or mobility problems; or the network device side can use the SON-related records reported by the UE (for example, MHI results) for various purposes including artificial intelligence (AI) and/or machine learning (ML) path prediction.

3. Types of NTN service links

The NTN service link is the connection between the UE and the NTN payload. There are three possible types:

(1) Earth-fixed: The satellite always remains in the same position relative to the ground, so the satellite beam providing coverage always continuously covers the same geographical area. In this scenario, the UE's mobility and other behaviors are basically the same between NTN cells and TN cells.

(2) Quasi-Earth-fixed: The satellite beam providing coverage covers 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 satellite beam does not move or change during one period of time, and is covered by another satellite beam during the next period of time.

(3) Earth moving: Coverage is provided by satellite beams that slide across the Earth’s surface. Since the satellite’s orbit is not synchronized with the Earth’s rotation, the NTN cell in this scenario is constantly moving.

4. NTN configuration information

NTN Configuration (NTN-Config): NTN auxiliary information, which provides the parameters required for the UE to access the NR NTN, including:

(1) Epoch Time: indicates the effective start time of NTN auxiliary information;

ntn-UlSyncValidityDuration: The validity duration configured by the network for NTN assistance information (i.e., serving cell and/or neighboring cell satellite ephemeris and common Timing Advance (TA) parameters), indicating the maximum duration (calculated from epochTime) that the UE can apply the assistance information without acquiring new assistance information.

(2) Ephemeris information (ephemerisInfo): Satellite ephemeris information, which can be in the format of position and velocity state vectors or orbital parameters;

(3) Timing Advance Information (ta-Info): includes common TA and drift-related parameters;

(4) Other information, such as TA reporting switch, time offset, polarization information of uplink and downlink transmission, etc.

Service Stop (t-Service): Indicates the time when the cell provided by the NTN system stops covering the current area. This field applies to service link switching in NTN Quasi-Earth Fixed and feeder link switching in NTN Quasi-Earth Fixed and Earth-moving systems.

Neighbor Cell Configuration Table (ntn-NeighCellConfigList): provides a list of NTN neighbor cells, including their NTN configuration (ntn-Config), carrier frequency, and PCI;

Reference Location: The reference location of the serving cell provided by the NTN quasi-terrestrial fixed system, used for starting location-based measurements in the RRC idle state (RRC_IDLE) and the RRC inactive state (RRC_INACTIVE).

MovingReferenceLocation: The reference location of the serving cell in the NTN Earth moving system at a certain time reference point. Used in location-based measurement triggers in RRC_IDLE and RRC_INACTIVE. The time reference of this field is indicated by the epochTime in the ntn-Config of the serving cell.

Distance threshold (distanceThresh): The distance threshold from the serving cell reference position, used for starting location-based measurements in RRC_IDLE and RRC_INACTIVE;

Satellite Switch with Resynchronization (satSwitchWithReSync): Provides the target satellite parameters required to perform satellite replacement and resynchronization, provided that the cell supports satellite replacement without changing the PCI. These parameters include the target satellite's NTN assistance information, the offset between the source and target satellite synchronization signal blocks (Synchronization Signal and PBCH block, SSB) required for possible soft satellite replacement, and the start time of coverage provided by the target satellite.

RACH-Less HO related parameters, including the TA and grant information used by the UE to perform non-random access handover.

5. NTN’s Unchanged PCI Satellite Replacement Mechanism

In the Quasi-Earth-fixed system of NTN, a satellite will cover a fixed geographic area for a period of time and this coverage will not change until the satellite leaves. When the currently providing coverage, satellite 0 (satellite 0), leaves and another satellite 1 (satellite 1) takes over, based on a reasonable satellite orbit layout and beam design, the upcoming cell 1 (Cell 1) can provide the same coverage as the current serving cell 0 (Cell 0). Moreover, by providing services through the same ground base station, two different satellites can provide the same service to the same area, so that the UE connected to the base station can use the same radio resource configuration. Therefore, the unchanged PCI mechanism can be used, so that the UE does not need to trigger the handover process to change the serving cell, but only needs to re-acquire the uplink and downlink synchronization with the target satellite, thereby avoiding the sending of handover commands during the handover process, saving overhead, and reducing data transmission interruption delay. The unchanged PCI mechanism includes two scenarios:

Hard satellite switch: The serving satellite switches at a fixed time T, with the source satellite serving before T and the target satellite serving after T. The terminal stops transmitting to the source cell at T and begins downlink synchronization with the target satellite.

Soft satellite switch: The source and target satellites can provide service or coverage to (almost) the same area for a period of time.

Considering that in a non-terrestrial network (NTN), when the service link is of Quasi-Earth-fixed type or Earth moving type, the satellites covering the same location and the locations of the cells covered by the satellites may be different or moving, which may result in the network equipment side being unable to determine which satellite or cell covered by the satellite to adjust the relevant parameters based on the SON and/or MDT reporting mechanism in the relevant technologies.

The disclosed embodiments provide an information processing method, apparatus, terminal, and network device to address the current lack of a solution for how terminals report SON and/or MDT for NTNs. The method and apparatus (or terminal or network device) are based on the same inventive concept. Because the principles underlying the problems solved by the method and apparatus (or terminal or network device) are similar, their implementations can refer to each other, and any repetitions will not be repeated.

As shown in FIG1 , an embodiment of the present disclosure provides an information processing method, comprising the following steps:

Step 11: The terminal sends a SON report and/or an MDT report to the first network device; wherein the SON report and/or the MDT report carries at least one of the following information:

second information related to NTN measurement of the terminal;

The third information is related to the change of the satellite and/or the change of the cell covered by the satellite.

In some embodiments, the first information includes but is not limited to: all parameters related to the satellite, or some parameters related to the satellite, or all parameters related to the cell covered by the satellite, or some parameters related to the satellite, etc. The embodiments of the present disclosure are not limited thereto.

For example, all parameters related to the unchanged PCI or some parameters related to the unchanged PCI; and/or all parameters related to RACH-LessHO or some parameters related to RACH-LessHO, etc., although the present disclosure is not limited thereto.

In the above solution, the terminal sends a SON report and/or MDT report to the first network device. The SON report and/or MDT report carries at least one of first information related to the satellite or the cell covered by the satellite, second information related to the terminal's non-terrestrial network (NTN) measurements, and third information related to satellite replacement and/or cell replacement covered by the satellite. This solution enables the terminal to report the NTN status of the SON and/or MDT records to the first network device under NTN conditions. This allows the first network device to determine, based on at least one of the first, second, and third information, which satellite or cell covered by the satellite to adjust the relevant parameters. This implements SON and/or MDT reporting under NTN conditions, resolving the current lack of a solution for how terminals can perform SON and/or MDT reporting under NTN conditions.

The configuration information includes at least one of the following, that is, the NTN reporting indication information includes at least one of the following:

The first indication information is used to indicate whether the terminal reports the first information; for example, the first indication information is an indication of whether the relevant parameters of the satellite or the cell covered by the satellite are carried. For example, the terminal receives the configuration information carrying the first indication information, that is, it is determined that the parameters related to the satellite or the cell covered by the satellite are carried in the SON report and/or the MDT report.

The second indication information is used to indicate whether the terminal reports the second information; for example, the second indication information is an indication of whether the NTN measurement-related parameters of the terminal are carried. For example, if the terminal receives the second indication information in the configuration information, it is determined that the NTN measurement-related parameters are carried in the SON report and/or the MDT report.

The fourth indication information is used to instruct the terminal to report some parameters in the first information; for example, the fourth indication information also instructs the terminal which parameters in the first information to report (for example, some parameters related to the satellite or the cell covered by the satellite), such as satellite identification information, NTN cell type, ephemeris information, etc.;

The fifth indication information is used to instruct the terminal to report some parameters in the second information; for example, the fifth indication information also instructs the terminal to report those parameters in the second information (such as some parameters related to the terminal's NTN measurement).

The sixth indication information is used to instruct the terminal to report some parameters in the third information; that is, the sixth indication information is used to instruct the terminal which parameters in the third information to report (for example, some parameters related to satellite replacement and/or cell replacement covered by the satellite).

In this embodiment, the network device configures for the terminal whether it needs to report one or more of the first information, the second information, and the third information, and/or the network device configures for the terminal which parameters in the first information need to be reported, which parameters in the second information need to be reported, and which parameters in the third information need to be reported. In this way, the terminal can report according to the requirements of the network device side, thereby ensuring that the content reported by the terminal can provide the network device for NTN optimization, and also reducing the waste of resource overhead caused by the terminal reporting a large amount of information.

In one or more embodiments, the method further comprises:

The terminal receives a system message or terminal-specific signaling sent by a first network device; wherein the system message or the terminal-specific signaling carries satellite identification information.

The terminal records the first information for an initial entry in the SON and/or MDT recording process;

The terminal records the first information for a specific entry in the SON and/or MDT recording process, wherein the first information corresponding to the specific entry is changed compared with the recorded first information.

For example, the terminal may record the first information in a manner such that the terminal records the first information separately for each entry in the SON and/or MDT recording process, that is, when the terminal records each entry in the SON and/or MDT recording process, the terminal records the corresponding first information separately for each entry.

For another example, the terminal may record the first information in such a manner that the terminal records the first information for a specific entry in the SON and/or MDT recording process, wherein the first information corresponding to the specific entry is changed compared to the recorded first information.

For another example, the terminal may record the first information in the following manner: the terminal records the first information for an initial entry in a SON and/or MDT recording process, and the terminal records the first information for a specific entry in a SON and/or MDT recording process, where the first information corresponding to the specific entry changes compared to the previously recorded first information. In other words, during the SON and/or MDT recording process, the terminal may start recording from the first entry, and record the first information when the first information in subsequent SON and/or MDT recording changes compared to the previously recorded first information.

It should be noted that when the terminal records the first information for a specific entry in the SON and/or MDT recording process, it may record all parameters in the first information for the specific entry, or it may record parameters in the first information that have changed compared to the previous record for the specific entry, etc. The embodiments of the present disclosure are not limited to this.

A first time interval between the moment when the terminal performs SON and/or MDT logging and the moment when the terminal sends a SON report and/or MDT report; for example, the first time interval may also be referred to as a first time length, that is, the length of time that elapses from the moment when the terminal performs SON and/or MDT logging to the moment when the terminal sends a SON report and/or MDT report.

The second time interval between the time when the terminal executes SON and/or MDT recording and the time when the terminal switches to the target satellite or the cell covered by the target satellite; for example, the second time interval may also be referred to as the second time length, i.e., the length of time that elapses from the time when the terminal executes SON and/or MDT recording to the time when the terminal switches to the target satellite or the cell covered by the target satellite. For example, the second time interval between the time when the terminal executes RLF report recording in SON and/or MDT recording and the time when the terminal switches to the target satellite. In this way, the network device can determine whether the occurrence of RLF is caused by the terminal switching to the target satellite based on the second time interval, thereby determining the correlation therebetween. Of course, the embodiments of the present disclosure are not limited to this.

A third time interval between the time when the terminal executes SON and/or MDT recording and the time when the terminal most recently executed SON and/or MDT recording; for example, the third time interval may be referred to as a third time length. For example, when the terminal executes SON and/or MDT recording multiple times, the time interval between adjacent records is the time length between two adjacent records executed by the terminal.

In this embodiment, the terminal reports at least one of the second information, so that the network device can learn the NTN information and/or location information related to the terminal, thereby ensuring that the network device can make more timely and accurate optimization strategies when performing NTN optimization.

The distance between the terminal and the reference position of the NTN serving cell. For example, the reference position of the NTN serving cell can be the reference point position issued by Quasi-Earth Fixed or the reference point position calculated based on ephemeris information issued by Earth-Moving. For example, the network device can issue the reference position of the NTN serving cell to the terminal, and the terminal can determine the distance between itself and the reference position of the NTN serving cell and report it to the network device.

The terminal's relative position relative to the reference position of the NTN serving cell. For example, the reference position of the NTN serving cell can be the reference point position issued by Quasi-Earth Fixed or the reference point position calculated based on ephemeris information issued by Earth-Moving. For example, the network device can issue the reference position of the NTN serving cell to the terminal, and the terminal can determine its relative position relative to the reference position of the NTN serving cell and report it to the network device.

The first network device sends a SON report to the second network device, where the SON report carries at least one of the first information, the second information, and the third information.

For example, after the first network device receives the SON report and/or MDT report reported by the terminal, the first network device can perform big data optimization based on the SON report and/or MDT report and generate an optimization strategy, or the first network device can optimize the parameters of the corresponding satellite or the cell covered by the satellite based on the SON report and/or MDT report and generate an optimization strategy, etc. The specific implementation may depend on the network side, and the embodiments of the present disclosure are not limited to this.

It should be noted that the first network device is a network device that receives the SON report and/or MDT report sent by the terminal, and the second network device can be the network device where the terminal performs SON recording, or the source network device or the target network device, etc. The embodiment of the present disclosure is not limited to this.

In one or some embodiments, before the first network device receives the SON report and/or MDT report sent by the terminal, the method further includes:

The first network device sends configuration information to the terminal; wherein the configuration information includes at least one of the following:

First indication information, used to instruct the terminal whether to report the first information;

In one or more embodiments, the method further comprises:

The first network device sends a system message or terminal-specific signaling to the terminal; wherein the system message or the terminal-specific signaling carries satellite identification information.

In some embodiments, the first information includes at least one of the following parameters:

Location information related to the terminal's location.

The time information related to the NTN measurement of the terminal includes at least one of the following:

Time information of sending SON report and/or MDT report by the terminal;

The absolute time when the terminal executes SON and/or MDT recording;

a first time interval between the terminal performing SON and/or MDT logging and the terminal sending a SON report and/or MDT report;

a second time interval between the terminal executing SON and/or MDT logging and the terminal switching to the target satellite or the cell covered by the target satellite;

a third time interval between the terminal performing SON and/or MDT logging and the terminal's most recently performed SON and/or MDT logging;

The first network device receives time information of the SON report and/or the MDT report sent by the terminal.

In one or some embodiments, after the first network device receives the SON report and/or MDT report sent by the terminal, the method further includes at least one of the following:

When the time information related to the terminal's NTN measurement includes the absolute time at which the terminal executed SON and/or MDT logging, the first network device performs NTN optimization based on the first information corresponding to the absolute time. For example, when the terminal reports the absolute time at which it executed SON and/or MDT logging, the first network device may associate the absolute time with relevant parameters of the satellite covering the terminal's location at the same time, or the cell covered by the satellite, to thereby determine a corresponding optimization strategy.

If the time information related to the terminal's NTN measurement does not include the absolute time at which the terminal executed SON and/or MDT logging, the first network device determines the absolute time at which the terminal executed SON and/or MDT logging based on the time information related to the terminal's NTN measurement, and performs NTN optimization based on the first information corresponding to the absolute time. For example, if the terminal does not directly report the absolute time, the first network device may calculate and derive the corresponding absolute time based on other NTN measurement-related time information reported by the terminal, and associate the absolute time with relevant parameters of the satellite covering the terminal's location at the same time, or the cell covered by the satellite, to thereby determine the corresponding optimization strategy.

In a case where the time information related to the terminal's NTN measurement does not include the absolute time at which the terminal executed SON and/or MDT recording, the first network device determines the absolute time at which the terminal executed SON and/or MDT recording based on the time information related to the terminal's NTN measurement, and sends first information corresponding to the absolute time to the OAM data collection device and/or the second network device. For example, in a case where the terminal does not directly report the absolute time, the first network device may calculate and derive the corresponding absolute time based on other NTN measurement-related time information reported by the terminal, and send the calculated absolute time to the OAM and/or second network device. The OAM and/or second network device then associates the absolute time with relevant parameters of the satellite or cell covered by the satellite at the same time, thereby determining a corresponding optimization strategy.

It should be noted that the first network device may also send time information related to NTN measurements to the OAM and/or second network device, and the OAM and/or second network device may associate the absolute time in the time information related to NTN measurements with relevant parameters of the satellites or cells covered by the satellites at the same time that cover the terminal's location, thereby determining a corresponding optimization strategy. Alternatively, the absolute time may be calculated or derived based on the time information related to NTN measurements, and the absolute time may be associated with relevant parameters of the satellites or cells covered by the satellites at the same time that cover the terminal's location, thereby determining a corresponding optimization strategy, etc. The embodiments of the present disclosure are not limited to this.

The terminal's geographical location information;

The distance between the terminal and the reference location of the NTN serving cell;

The relative location information of the terminal relative to the reference location of the NTN serving cell.

In some embodiments, the third information includes at least one of the following parameters:

Eighth indication information, used to indicate whether the terminal is configured with satellite change of RACH-Less handover and/or cell change of satellite coverage;

Delay information related to the transmission delay of the terminal to the source satellite and/or the transmission delay of the terminal to the target satellite;

RACH information related to uplink data not being sent successfully before TAT timeout.

It should be noted that the information processing method on the first network device side in the embodiment of the present disclosure and the information processing method on the terminal side are based on the same inventive concept. The two embodiments can refer to each other and can achieve the same technical effect. To avoid repetition, they will not be repeated here.

The network device involved in the embodiments of the present disclosure may be a base station, which may include multiple cells providing services to the terminal. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The network device can be used to interchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present disclosure may be a network device (Base Transceiver Station, BTS) in the Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), or a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolved network device (evolutionary Node B, eNB or e-NodeB) in the Long Term Evolution (LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), or a Home evolved Node B (HeNB), a relay node, a femto base station, a pico base station, etc., but is not limited in the embodiments of the present disclosure. In some network structures, network devices may include centralized unit (CU) nodes and distributed unit (DU) nodes, and the centralized unit and the distributed unit may also be geographically separated.

The information processing method disclosed herein is described below with reference to specific embodiments:

Embodiment 1: When the UE performs recording of relevant information for various SON and/or MDT optimization features such as RLF/HOF/CEF/RA report or SHR/SPR/MHI, the UE may record relevant parameters of the satellite or the cell covered by the satellite (i.e., first information), and carry the relevant parameters of the satellite or the cell covered by the satellite in the SON report and/or MDT report sent to the first network device;

Parameters related to a satellite or a cell covered by a satellite may include:

(1) Satellite identification related information can be the name/number index of the satellite or the cell covered by the satellite. Satellite identification related information can be sent to the UE by the network device when the UE accesses the NTN network. When the satellite providing the service link for the UE or the cell covered by the satellite changes, the UE will obtain the satellite identification related information after the change from the network device; the way in which the UE obtains the satellite identification information from the network device can be through system information (such as SIB19) or through terminal-specific signaling (such as reconfiguration message/handover command). When the UE performs SON and/or MDT logging, the UE also records the satellite identification related information;

(2) NTN cell type, such as Quasi-Earth-fixed type or Earth-moving type;

(3) NTN auxiliary information may include but is not limited to:

a. Satellite ephemeris information, which can be the satellite ephemeris information in the NTN configuration sent by the network device;

b. Timing advance related information, which may be TA related information in the NTN configuration sent by the network device;

The validity duration of the satellite ephemeris information can be ntn-UlSyncValidityDuration in the NTN configuration sent by the network device;

The effective expiration time of the satellite ephemeris information may be an expiration time calculated based on the effective start time and duration;

The valid time information of the timing advance related information includes at least one of the following:

The effective start time of the timing advance related information can be the epochTime in the NTN configuration sent by the network device;

The validity duration of the timing advance related information can be ntn-UlSyncValidityDuration in the NTN configuration sent by the network device;

The effective expiration time of the timing advance related information may be an expiration time calculated based on the effective start time and duration time;

(4) The reference position of the NTN serving cell, such as the reference point position sent by the network equipment in the Quasi-Earth fixed system, or the reference point position calculated by the UE based on the sent reference point position and ephemeris information in the Earth-moving system;

(5) cell information of NTN neighboring cells. The cell information of the NTN neighboring cells may be a list of NTN neighboring cells sent by the network device. The cell information of the NTN neighboring cells may include: a neighboring cell identifier and/or ntn-Config of each neighboring cell;

(6) Time information related to changes in the NTN cell coverage area, including at least one of the following:

Information about the time when the NTN cell stops covering the current area, such as the t-service configured by the network;

In a soft satellite switch scenario, the network configuration specifies when the current NTN cell stops covering the network and when the next NTN cell starts covering the network.

In a soft satellite switch scenario, the network-configured time at which the current NTN cell stops covering the network, and the interval between it and the time at which the next NTN cell starts covering the network;

(7) For the SON characteristics recorded in the RLF report, such as HOF handover failure, successful SHR handover after critical failure, successful PSCell addition or change after critical failure, etc., whether it is an indication of non-random access handover (i.e., the eighth indication information), and/or non-random access handover related configuration information (i.e., RACH-Less handover configuration information).

When the first network device sends an MDT report to the OAM, or sends a SON report to the network-side device/source network-side device/target network-side device where the UE is performing the recording, the first network device carries relevant parameters of the satellite or the cell covered by the satellite. The network-side device/source network-side device/target network-side device where the UE is performing the recording can all be understood as the second network device.

Based on the reporting of relevant parameters of satellites or cells covered by satellites, network equipment/OAM can obtain satellite information and/or information related to cells covered by satellites when the UE executes SON and/or MDT records (for example: UE RLF/HOF occurs, or a successful handover with a critical failure/a successful PSCell addition or change with a critical failure occurs, or the UE coverage-related information of a certain entry in the logged MDT is recorded, etc.), so as to optimize the parameters of the corresponding satellites or cells covered by satellites in a targeted manner, or perform big data statistics to generate optimization strategies.

Embodiment 2: SON report and/or MDT report carries time information related to NTN measurement of the terminal (ie, NTN time-related parameters)

When the UE performs recording of relevant information for various SON and/or MDT optimization features such as RLF/HOF/CEF/RA report or SHR/SPR/MHI, the UE may record NTN time-related parameters and/or UE location-related information, and carry the NTN time-related parameters and/or UE location-related information in the SON report and/or MDT report sent to the network;

NTN time-related parameters may include:

(1) The absolute time when the UE performs SON and/or MDT logging, such as UTC or GPS time;

(2) a first time interval between the time when the UE performs SON and/or MDT logging and the time when the UE sends a SON report and/or MDT report;

(3) When the UE performs SON and/or MDT records multiple times (e.g., RACH report, CEF report, MHI), the time interval between adjacent records; for example, the UE records RA-related information A/B/C three times for different RACH occurrence times, and the UE records the time intervals between A and B, and B and C. Combined with the time length between the UE's last record of C and the UE's report transmission, the network device can reversely infer the time points at which all records A/B/C occurred;

(4) Time information when the UE sends the SON report and/or MDT report, such as UTC or GPS time;

(5) The time interval between the time when the UE performs SON and/or MDT logging and the time when the terminal switches to the target satellite or the cell covered by the target satellite.

After receiving the sent SON report and/or MDT report, the network device M (i.e., the first network device) may send the current time information, such as absolute time information, at the same time when sending the SON report to the network side device/source network side device/target network side device N (i.e., the second network device) where the UE performs recording, or when sending the MDT report to the OAM;

The network-side device N that receives the SON report, or the OAM that receives the MDT report, can successfully deduce the time information of the UE record by receiving the time information recorded by the network-side device M and/or the NTN time-related parameters reported by the UE, thereby corresponding to the NTN network information at that time, or the satellite or cell information covered by the satellite, and can optimize the parameters of the corresponding satellite or cell covered by the satellite in a targeted manner;

The network-side equipment that receives the SON report, or the OAM that receives the MDT report, can determine whether the satellite coverage before and after the satellite change is consistent based on the time difference between the UE executing the SON and/or MDT record and the UE executing the target satellite change, thereby determining the UE's RACH demand when the satellite is changed;

UE location-related information may include:

a. Geographical location information of the terminal, such as the geographical location coordinate information of the terminal;

b. Relative position information of the UE relative to the reference position of the NTN serving cell, for example, the distance and/or relative position of the terminal from the reference position of the NTN serving cell;

The network-side device that receives the SON report, or the OAM that receives the MDT report, can determine whether UEs in a specific location/range are prone to link-related problems based on the information related to the UE location recorded when the UE executes SON and/or MDT, combined with the above-mentioned other UE reporting information, and thus adopt optimization mechanisms such as coverage enhancement.

Example 3: Logged MDT configuration and parameters related to Earth-moving satellites or cells covered by satellites

For Logged MDT, the network device is supported to send MDT configuration information to the UE. Therefore, in the MDT configuration, the network device can configure NTN reporting indication information (i.e., configuration information) to the UE. The configuration information includes at least one of the following: an indication for indicating whether the UE reports relevant parameters of the satellite or the cell covered by the satellite, an indication for indicating whether the UE reports some parameters of the relevant parameters of the satellite or the cell covered by the satellite; the configuration information includes, for example, whether it carries satellite identification information, whether it carries the NTN cell type, and/or whether it carries ephemeris information, etc.

The UE can record one or more entries for Logged MDT, each of which records coverage information at different times. Similarly, some SON features support multiple entries, each of which records information about the corresponding SON feature (for example, an RA report records information about each random access (RA) event).

When the UE records the SON and/or MDT reporting information and the related parameters of the satellite or the cell covered by the satellite, the parameters may be:

(1) When executing SON and/or MDT to record each entry, the UE records the relevant parameters of the satellite or the cell covered by the satellite;

(2) When executing the initial SON and MDT logging, the UE records the relevant parameters of the satellite or the cell covered by the satellite, and/or the UE records the relevant parameters of the satellite or the cell covered by the satellite for a specific entry in the SON and/or MDT logging process, wherein the relevant parameters of the satellite or the cell covered by the satellite corresponding to the specific entry are changed compared with the relevant parameters of the satellite or the cell covered by the satellite that have been recorded;

(3) For the content recorded in (2) above, only the content that has changed may be recorded. For example, for an Earth-moving system, since the reference position of the serving cell changes over time, the UE may calculate the reference point position at the time of recording the corresponding SON and/or MDT entry based on the initial reference point position (e.g., movingReferenceLocation) sent by the network device and the ephemeris information, and record it in the entry for reporting.

When the network device/OAM receives the SON records of (2) and/or (3) above, and/or the network device/OAM receives the MDT records of (2) and/or (3) above, for entries carrying relevant parameters of satellites or cells covered by satellites, the relevant parameters are directly used; for relevant parameters of some/all satellites or cells covered by satellites not carried in entry X, the relevant parameters of satellites or cells covered by satellites carried in entry Y that is the closest to entry X and carries relevant parameters of satellites or cells covered by satellites are used for the relevant parameters of satellites or cells covered by satellites at the time of recording of entry X.

Example 4: Carrying relevant parameters in historical information reporting

The historical information records reported in SON and/or MDT include UE history information (UE History Information, UHI) and/or mobility history information (Mobility History Information, MHI).

In the MHI mechanism of related technologies, the UE records the Primary Cell (PCell) and/or PSCell accessed along its mobile path, as well as information such as the time of access to each of these cells. After receiving the UE report, the network device can infer the UE's historical path information based on the UE's access and residence/connection time in different cells, and then predict/optimize the path. MHI is recorded and reported on the UE side, and the UE record does not distinguish between RRC connected, inactive, and idle states.

The UHI mechanism in related technologies records the PCell and/or PSCell accessed by the UE during its mobility path, as well as information such as the time of access to each of these cells. Unlike MHI, UHI recording is performed by the network (e.g., the base station) and only supports recording in the RRC connected state.

Compared with TN networks, NTN networks have a larger coverage area for a single cell. Furthermore, for Quasi-Earth fixed and Earth-moving systems, the satellites covering the same location at different times and the cell locations under satellite coverage may be different or moving. If the historical information recording and reporting mechanism in related technologies is applied, even if the UE does not move or moves slowly (for example, it does not leave the coverage area of the current cell), frequent MHI/UHI records will be generated due to the rapid changes in the position between the satellite and the Earth. These records do not reflect the changes in the UE's mobile location, but they will occupy limited record entries, causing redundancy.

Therefore, for historical information recording and reporting, in addition to enhancing the above satellite/cell/time related information, it is also possible to:

(1) When the UE/network device detects a change in key information, it is allowed to record an entry. The key information change includes at least one of the following:

a. The network device configuration information changes, for example, the reference point position changes, the ephemeris information changes;

b. The PCI to which the UE is connected is changed, provided that the UE/network device supports the unchanged PCI mechanism.

(2) Set a prohibition timer. Each time a record is made, the timer is started/restarted. Only when the timer times out/times out, the UE/network device is allowed to record an entry.

Example 5: Reporting information related to the unchanged PCI mechanism and/or the rach-LessHO mechanism

When the UE/network equipment supports the unchanged PCI mechanism and/or the rach-LessHO mechanism, when the UE performs recording of relevant information for the SON and/or MDT optimization features, it may record relevant information of the unchanged PCI and/or the rach-LessHO, and carry relevant information of the unchanged PCI and/or the rach-LessHO in the SON report and/or MDT report sent to the network.

unchanged PCI related information and/or rach-LessHO related information include but are not limited to the following:

(1) Whether the network device is configured with instructions for satellite replacement of unchanged PCI;

(2) Whether the network equipment is configured with relevant instructions for satellite replacement for RACH-Less handover and/or replacement of cells covered by satellites;

(3) unchanged PCI configuration information; and/or, RACH-Less handover configuration information;

(4) Whether the UE performs satellite change for RACH-Less handover and/or cell change for satellite coverage;

(5) Whether the UE successfully completes the satellite replacement without changing the PCI of RACH-Less;

(6) Delay information related to the transmission delay of the UE to the source satellite and/or the transmission delay of the terminal to the target satellite, such as the propagation delay difference, the TA difference, and/or whether the TA difference is greater than a threshold configured by the network;

(7) Random access channel (RACH) information related to the unsuccessful transmission of uplink data before the time adjustment timer (TAT) expires.

Based on this information, the network device can identify issues that may occur when the network device configures the UE in an unchanged PCI scenario and/or a rach-less HO scenario, and perform relevant optimization operations. For example, by measuring the latency correlation between the UE and the source and target satellites during a satellite change, it can determine whether to send a Physical Downlink Control Channel (PDCCH) order to trigger the necessary RACH process for UEs in a specific area or geographic location.

In summary, the embodiments of the present disclosure provide an information processing method, which is a method for reporting NTN network information records for SON and/or MDT measurement records in an NTN scenario, so as to inform the network UE of the NTN network information when performing information recording. For the NTN network satellite mobile scenario, the method restores the NTN network status at the time of SON and/or MDT measurement recording to the network as accurately as possible.
