Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to an information reporting method, a terminal, and network-side equipment. Background Technology

[0002] In the field of communication technology, network-side devices can optimize the communication process of RRC connected terminals based on predicted terminal movement trajectories, such as handover preparation and avoiding ping-pong handover. Typically, predicting terminal movement trajectories can be achieved in several ways: the network-side device predicts based on deployment conditions and geographical environment; the network-side device predicts based on historical movement information reported by the terminal and the serving cell of the terminal in RRC connected state; or the RRC connected terminal reports its predicted movement trajectory to the network-side device.

[0003] In related technologies, network-side devices can only predict the terminal's movement trajectory when the terminal is in an RRC connected state. However, when the terminal is in an RRC idle state or an RRC inactive state (i.e., an RRC disconnected state), the RRC connection between the network-side device and the terminal is broken. Therefore, the network-side device cannot obtain the predicted movement trajectory of the terminal during the RRC idle state or the RRC inactive state, or cannot effectively predict the movement trajectory of the terminal during the RRC idle state or the RRC inactive state.

[0055] The following explanations and descriptions will be provided regarding some concepts, terms, or related technologies involved in the information reporting method, terminal, and network-side equipment provided in the embodiments of this application.

[0056] 1. Reporting of UAV flight path information

[0057] Unmanned Aerial Vehicles (UAVs) typically follow a defined flight path. When in RRC (Remote Routing Control) connected state, the UAV reports this flight path information to the network. The network can then use this information for RRC connected state mobility management, such as handover preparation. Therefore, both LTE and NR protocols have introduced a UAV flight path information reporting mechanism.

[0058] Specifically, when a terminal possesses aircraft trajectory information, it can first indicate to the network side that it has a valid flight trajectory in the following messages: RRC connection establishment completion message, RRC connection restoration completion message, RRC connection reconstruction completion message, RRC reconfiguration completion message, and terminal auxiliary information (NR only). Subsequently, if the network side is interested in the terminal's flight trajectory, it can request it from the terminal via a UE Information Request message. The terminal can then report its flight path info via a UE Information Response message. The flight path info includes waypoints along the planned path and their corresponding estimated arrival times. In NR, to reduce signaling overhead from reporting, time / distance thresholds are introduced to control whether the terminal reports only when the flight trajectory changes significantly.

[0059] Flight path information can also be forwarded from the source base station to the target base station during handover. Flight path information is reported to the base station for the handover process of the terminal in the RRC connected state. When the terminal enters the RRC idle or RRC inactive state, the terminal assumes that the previously reported information will be released by the base station.

[0060] 2. Registration Update

[0061] A user must register with the network to access its services. When a terminal registers with the network, the AMF assigns it a registration area, which includes a series of tracking areas provided by a Tracking Area Identity (TAI) list. The AMF will then only page the terminal within the registration area. The TAI consists of a Mobile Country Code (MCC), a Mobile Network Code (MNC), and a 3-byte Tracking Area Code (TAC).

[0062] Once registered, the terminal needs to perform a registration update according to the conditions defined in the standard:

[0063] Periodic registration update: When the periodic timer expires, the terminal executes the periodic registration update process.

[0064] Mobility Registration Update (MRU): When a terminal leaves its current registration area, it executes an MRU. The terminal's registration area is a TAI list. If the serving cell's TAI is not in the terminal's TAI list, the terminal determines that it has left its current registration area.

[0065] The MRU process is triggered when the terminal needs to update its capability information or renegotiate protocol parameters with the network side.

[0066] 3. Terminal location information transmission via N2 interface

[0067] The N2 interface supports transmitting user location information from the base station to the AMF. This means that the core network can subscribe to the terminal's serving cell information (e.g., the TAI and cell where the terminal is located each time an RRC connection is initiated) from the base station. The core network can collect this information to obtain the terminal's movement trajectory.

[0068] 4. Terminal movement trajectory reporting

[0069] LTE and NR introduce the following mechanism: Terminals record their historical mobility information (such as historical serving cell / historical camped cell, service duration / camped duration) in the RRC idle / inactive / connected states. During the process of entering the connected state (such as RRC connection establishment completion message, RRC connection recovery completion message), they can indicate to the network side that they have historical mobility information. If the network side is interested, it can request the terminal to report the historical mobility information.

[0070] The terminal will only delete its local historical mobility information when it registers with the core network. The base station can send the terminal's reported historical mobility information to the core network or network elements such as operations administration and maintenance (OAM) for storage. When the terminal subsequently initiates an RRC connection in a serving cell and enters the connected state, the current serving base station can obtain the terminal's historical mobility information from the aforementioned network elements and, based on the terminal's current location, estimate the duration of the terminal's stay at the current location or the terminal's next serving cell to prepare for handover. Furthermore, during handover, the terminal's historical mobility information can also be exchanged via the Xn interface during the handover preparation process.

[0071] 5. Terminal trajectory prediction based on artificial intelligence (AI)

[0072] The RAN3 standard introduces a feature where base stations use AI to predict the trajectory information of terminals in the RRC connected state, specifically predicting the future serving cell identity (ID) and the corresponding expected service duration. This predicted trajectory information can be used by the network to select target cells.

[0073] 6. Network energy saving

[0074] With the development of mobile communication technology, fifth-generation (5G) mobile communication base stations have entered a stage of large-scale deployment. While 5G base stations can provide more powerful communication services, the resulting high energy consumption has significantly increased the operating costs of mobile operators. Reducing the energy consumption of 5G base stations has become a pressing issue for operators. Most of the power consumption of 5G networks comes from base stations, and 90% of the power consumption of NR base stations comes from active antenna units (AAUs). Due to higher frequency bands, wider bandwidth, and more carrier frequencies (transceivers, TRX), the power consumption of a single NR base station is currently 3 to 4 times higher than that of LTE. Furthermore, in terms of operating expenses (OPEX), base station electricity costs account for nearly 20% of the total network operating costs. For some operators, electricity costs account for more than half of their total profits. Therefore, energy saving in NR networks is becoming increasingly critical to achieving the great success of 5G. Depending on the actual load, base stations can implement different levels of energy-saving measures, such as shutting down the base station, shutting down carriers / cells, shutting down channels, shutting down single sideband (SSB) communication / beams, shutting down antennas / panels, cell discontinuous transmission (cell DTX) and / or cell discontinuous reception (cell DRX), adaptive channel state information (CSI), on-demand request for System Information Block 1 (SIB1), on-demand request for SSB, on-demand request for Open System Interconnect (OSI), etc.

[0075] 7. When there is no data transmission from the terminal, the network will often release the terminal's RRC connection, putting the terminal in an RRC idle / inactive state. This can reduce the handover signaling overhead caused by the terminal moving at high speed when there is no data transmission requirement, and can also reduce the power consumption of the terminal (because the terminal needs to perform radio link monitoring (RLM) in the connected state).

[0076] 8. To ensure the terminal can initiate services at any time, in RRC disconnected state, the terminal needs to perform cell selection and reselection based on system messages and synchronization signals sent by the network side, camping on a cell with acceptable signal quality. When a service arrives at the network side, the network needs to page the terminal at all base stations in the entire registration area / RAN notification area. When an uplink service occurs, the terminal initiates access in the currently camped cell.

[0077] The information reporting method, terminal, and network-side device provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0078] In related technologies, the movement trajectory of terminals is often predictable. Based on this predicted trajectory, networks can optimize communication processes, such as handover preparation and avoiding ping-pong handovers. The prediction methods in these technologies include the following:

[0079] a. The network predicts the terminal's movement trajectory based on deployment and geographical environment (such as high-speed rail environment);

[0080] b. In cases where the network cannot predict the situation, the terminal can record its historical movement trajectory and report it to the network side. The network side combines the terminal's historical movement trajectory with the serving cell when the terminal is in the current RRC connection state to predict the terminal's subsequent movement trajectory.

[0081] c. The terminal (such as a UAV) has a planned path, thus having a predicted movement trajectory. The terminal reports the planned movement trajectory to the network side.

[0082] In related technologies, the network side only predicts or obtains the predicted movement trajectory of the terminal when the terminal is in RRC connected state, for the purpose of mobility management in RRC connected state. In reality, the regularity of the terminal's movement trajectory is independent of its RRC state; the terminal may also have a predicted movement trajectory in RRC idle / inactive state. This trajectory helps the network side to perform targeted paging, optimize the transmission of synchronization signals and system information, thereby improving network energy efficiency. However, the network side cannot know whether a terminal in RRC idle / inactive state has movement trajectory information, nor can it effectively predict the terminal's movement trajectory during RRC idle / inactive state.

[0083] In other words, the network cannot know the movement trajectory information of terminals in the RRC idle / inactive state, nor can it effectively predict the terminal's movement trajectory during the RRC idle / inactive state. Therefore, it cannot perform directional paging or optimize the transmission of base station public signals, resulting in low network energy efficiency. For the terminal, it also cannot reduce the power consumption generated by frequently requesting the network's energy-saving cells to transmit system information during movement in the RRC disconnected state.

[0084] Therefore, this application provides an information reporting method. When the terminal is in an RRC disconnected state and has first movement trajectory information, the terminal initiates a first process and, during or after initiating the first process, indicates the first movement trajectory information to the network-side device. Wherein, when the terminal is in an RRC idle state, the first process is an RRC connection establishment process; when the terminal is in an RRC inactive state, the first process is an RRC connection recovery process or an SDT process. Compared to related technologies where network-side devices can only acquire predicted mobile trajectory information when the terminal has it and is in RRC connected state, and cannot acquire it in a timely manner when the terminal is in RRC disconnected state, this solution, when the terminal is in RRC disconnected state but has predicted mobile trajectory information, allows the terminal to initiate a first process and, during or after initiating the first process, indicate its mobile trajectory information to the network-side device. This achieves the goal of quickly entering RRC connected state and reporting its mobile trajectory information to the network-side device, enabling the network-side device to know the terminal's mobile trajectory information. Therefore, when the terminal is in RRC disconnected state, the network-side device can use the acquired mobile trajectory information to perform directional paging and optimize the transmission of base station public signals, thereby improving network energy efficiency.

[0085] This application provides an information reporting method. Figure 2 A flowchart illustrating the information reporting method provided in an embodiment of this application is shown. Figure 2 As shown, the information reporting method provided in this application embodiment may include the following step 201.

[0086] Step 201: When the terminal is in an RRC disconnected state and has the first movement trajectory information, the terminal initiates the first process and, during the initiation of the first process or after the completion of the first process, indicates the first movement trajectory information to the network-side device.

[0087] It is understood that a terminal being in an RRC disconnected state and possessing first movement trajectory information can trigger the terminal to initiate a first procedure to indicate the first movement trajectory information to the network side; or, a terminal being in an RRC disconnected state and possessing first movement trajectory information can trigger the terminal to indicate the first movement trajectory information to the network side; or, once the terminal in an RRC disconnected state possesses first movement trajectory information, the terminal initiates a first procedure to indicate the first movement trajectory information to the network-side device; or, once the terminal in an RRC disconnected state possesses first movement trajectory information, the terminal indicates the first movement trajectory information to the network-side device.

[0088] In one embodiment, the terminal instructing the network side to provide first movement trajectory information includes: the terminal instructing the network side to provide first movement trajectory information, receiving a request from the network side for the first movement trajectory information, and the terminal reporting the first movement trajectory information to the network side.

[0089] In this embodiment of the application, the above-mentioned RRC non-connected state includes the RRC idle state and the RRC inactive state.

[0090] In this embodiment of the application, when the terminal is in the RRC idle state, the above-mentioned first process is the RRC connection establishment process.

[0091] In this embodiment of the application, when the terminal is in an RRC inactive state, the first process described above is an RRC connection recovery process or an SDT process.

[0092] In this embodiment of the application, the first movement trajectory information mentioned above represents the terminal's predicted future movement trajectory.

[0093] Optionally, in this embodiment of the application, the first movement trajectory information may include cell dwell information or location dwell information.

[0094] For example, the cell dwell information mentioned above may include at least one of the following: cell identification information, dwell timestamp in the cell, and dwell duration in the cell. For instance, the cell identification information may be the NR Cell Global Identifier (NCGI) or the Physical Cell Identifier plus carrier information (PCI+carrier).

[0095] For example, the aforementioned residency timestamp can be an absolute timestamp, such as Universal Time Coordinated (UTC).

[0096] For example, the location information mentioned above can be GPS-based location information.

[0097] For example, the location stay information may include at least one of location information, a stay timestamp at the location indicated by the location information, and the stay duration at the location indicated by the location information.

[0098] Optionally, in this embodiment of the application, the first movement trajectory information may include at least one of the following:

[0099] The terminal predicts the identification information of at least one cell where it will be camped;

[0100] The terminal's predicted dwell time stamp in at least one cell;

[0101] The terminal's predicted dwell time in at least one cell.

[0102] For example, the identification information of at least one cell that the terminal predicts to reside in can be in the form of a cell list, which includes the identification information of at least one cell.

[0103] Optionally, in this embodiment of the application, the first movement trajectory information may include at least one of the following:

[0104] At least one location information predicted by the terminal;

[0105] The terminal predicts the dwell time stamp corresponding to at least one location information;

[0106] The terminal predicts the dwell time at at least one location.

[0107] In this embodiment of the application, after the network-side device obtains at least one location information predicted by the terminal, it can deduce the cell where the terminal is camped based on the at least one location information.

[0108] It is understandable that the dwell timestamp predicted by the terminal at at least one location information refers to the dwell timestamp predicted by the terminal at the location indicated by at least one location information.

[0109] It is understandable that the terminal's predicted dwell time at at least one location refers to the terminal's predicted dwell time at the location indicated by at least one location.

[0110] In this way, after the terminal indicates the first movement trajectory information to the network-side device, even when the terminal returns to the RRC disconnected state, the network-side device can still know the terminal's future movement trajectory, which facilitates the network-side device to perform directional paging and optimize the transmission of base station public signals.

[0111] Optionally, in this embodiment of the application, the terminal having first movement trajectory information may include any one of the following:

[0112] The terminal has predictable cell dwell information or arbitrary location information;

[0113] The terminal has predicted movement trajectory information that meets specific conditions, which are conditions satisfied by the cells or locations included in the movement trajectory information.

[0114] It is understandable that when a terminal has predicted cell dwell information or arbitrary location information, it means that the terminal has predicted cell dwell information in any cell or location information in any location.

[0115] It is understandable that when a terminal has predicted movement trajectory information that meets specific conditions, it means that the terminal has predicted dwell information or location information that meets specific conditions.

[0116] Optionally, in the embodiments of this application, the above-mentioned specific conditions include at least one of the following:

[0117] The number of cells or locations included in the movement trajectory information is greater than or equal to N, where N is an integer greater than or equal to 1;

[0118] The dwell time of each cell or the dwell time at each location included in the movement trajectory information is greater than or equal to the preset duration;

[0119] The number of historical repetitions of a cell or location included in the movement trajectory information is greater than or equal to M, where M is an integer greater than or equal to 1.

[0120] Optionally, in this embodiment of the application, the historical repetition count of the aforementioned cell refers to the number of times the terminal previously stayed in that cell, and the historical repetition count of the aforementioned location refers to the number of times the terminal previously stayed in that location.

[0121] It is understandable that if the dwell time of each cell or the dwell time of each location included in the above-mentioned mobile trajectory information is greater than or equal to the preset duration, then the mobile trajectory information is a predicted trajectory of the terminal over a relatively long period of time.

[0122] It is understandable that if the number of historical repetitions of cells or locations included in the above-mentioned movement trajectory information is greater than or equal to M, then the movement trajectory information includes more cells or locations where the terminal previously stayed, and the accuracy of the movement trajectory information is higher.

[0123] It should be noted that if the terminal predicts movement trajectory information over a short time period or makes predictions based on a small number of samples, reporting this movement trajectory information will not bring significant benefits to the network and the terminal; instead, it will increase the system's energy consumption. Therefore, the specific conditions mentioned above impose some constraints on the movement trajectory information reported by the terminal, reducing unnecessary triggering of the first process and reporting of the terminal's movement trajectory information.

[0124] For example, specific conditions may include at least one of the following:

[0125] The movement trajectory information includes the stationing information of N cells or N location points;

[0126] The start and end times in the movement trajectory information are not shorter than X;

[0127] The number of historical repetitions of cell or location information included in the movement trajectory information is not less than M;

[0128] It should be noted that X above refers to the preset duration.

[0129] Optionally, in this embodiment, N and M can be specified by a protocol, predefined, or configured by the network. For example, N equals 1 to indicate that the terminal's trajectory information is available. For example, N is 5, X is 30 minutes, and M is 10.

[0130] In this way, if the terminal indicates the first mobile trajectory information to the network-side device when the predicted first mobile trajectory information includes a sufficient number of cells or locations, or when the predicted first mobile trajectory information is a trajectory over a sufficiently long period of time, or when the accuracy of the predicted first mobile trajectory information is higher, the accuracy of the indicated first mobile trajectory information will be higher, unnecessary trajectory information reporting will be reduced, and the system's energy consumption will be lowered.

[0131] Optionally, in this embodiment of the application, the terminal may record the terminal’s historical movement information based on internal implementation or in a standardized manner, and predict the terminal’s movement trajectory in the future period of time based on the terminal’s current movement behavior (such as the cell or area where it stays for a period of time).

[0132] Optionally, in this embodiment of the application, the step 201 above, "the terminal initiating the first process or after the first process ends, instructs the network-side device to provide the first movement trajectory information", can be specifically implemented through the following steps 201a or 201b.

[0133] Step 201a: During the initiation of the first process or after the completion of the first process, if the terminal has not reported the first movement trajectory information, the terminal sends the first movement trajectory information to the network-side device.

[0134] Step 201b: During the initiation of the first process or after the completion of the first process, if the terminal has previously reported the first movement trajectory information and the first movement trajectory information is in an invalid state, the terminal sends the first indication information to the network-side device.

[0135] In this embodiment of the application, the first indication information indicates that the first movement trajectory information has been restored to a valid state.

[0136] In this embodiment of the application, the first indication information includes the identifier of the first movement trajectory information.

[0137] For example, if a terminal reports first movement trajectory information at time T1, and then reports second movement trajectory information after changing the movement trajectory information at time T2 (the network side may default to the first movement trajectory information being invalid, but still save it), and at time T3 the terminal predicts that its movement trajectory information is the first movement trajectory information again, then the terminal sends a first indication message to the network side device. This first indication message includes an identifier for the first movement trajectory information (the network side may default to the first movement trajectory information being valid again). Further, when reporting the second movement trajectory information, the terminal can explicitly indicate to the network side that the first movement trajectory information is invalid or that the first movement trajectory information is movement trajectory information that the terminal will use multiple times. In this way, the network side can decide to save the first movement trajectory information, assign an associated identifier, and send it to the terminal. If, at time T3 the terminal predicts that its movement trajectory information is the first movement trajectory information again, then the terminal sends a first indication message to the network side device. This first indication message includes an identifier for the first movement trajectory information, which is an identifier assigned to the terminal by the network side. In other implementations, the identifier for the movement trajectory information may also be provided by the terminal when reporting the movement trajectory information.

[0138] For example, a terminal can report multiple sets of movement trajectory information at once. While the terminal is in an RRC disconnected state, upon determining one set of movement trajectory information, it initiates a first process. During or after the first process, it indicates the movement trajectory information to the network side. This reduces the signaling overhead of the terminal reporting movement trajectory information and improves interaction efficiency. In this example, when reporting multiple sets of movement trajectory information, the terminal provides identification information for each set of movement trajectory information.

[0139] Optionally, in this embodiment of the application, after step 201 above, the information reporting method provided in this embodiment of the application further includes at least one of the following:

[0140] If the first movement trajectory information becomes invalid, the terminal indicates to the network-side device that the first movement trajectory information is invalid.

[0141] If the terminal's first movement trajectory information changes, the terminal indicates the updated first movement trajectory information to the network-side device.

[0142] This avoids the network side using inaccurate movement trajectory information, which could cause terminals in the RRC non-connected state to not receive paging messages, or prevent the network side from improving network power consumption.

[0143] Optionally, in this embodiment of the application, the aforementioned "terminal instructing the network-side device to update the first movement trajectory information" may include at least one of the following:

[0144] If permitted by the network-side device, the terminal indicates the updated first movement trajectory information to the network-side device;

[0145] When the change in the terminal's first movement trajectory information meets a preset threshold, the terminal indicates the updated first movement trajectory information to the network-side device.

[0146] For example, the network-side device may send configuration information to the terminal, which indicates that the terminal is allowed to report updated first movement trajectory information.

[0147] For example, to control the frequent initiation of the first process caused by the terminal frequently changing its movement trajectory, the following mechanism can be used: The network side can configure a preset threshold (or a protocol agreement). When the terminal's expected deviation exceeds the preset threshold, the terminal initiates the aforementioned first process. This is on the premise that the network implementation can expand the paging range based on the information reported by the terminal. Alternatively, the network side can flexibly enable / disable the terminal from reporting movement trajectory information.

[0148] It should be noted that the first process initiated by the aforementioned terminal is the terminal instructing the network-side device to update the first movement trajectory information.

[0149] This reduces the frequency of initiating the first process caused by the terminal frequently changing its movement trajectory, thus reducing unnecessary operations.

[0150] Optionally, in this embodiment of the application, the terminal instructing the network-side device to update the first movement trajectory information can be specifically implemented through the following step 301.

[0151] Step 301: The terminal indicates the second movement trajectory information to the network-side device. The second movement trajectory information is different from the first movement trajectory information.

[0152] Optionally, in this embodiment of the application, when the cell information or location information in the first movement trajectory information and the second movement trajectory information are the same, the second movement trajectory information includes a dwell time offset or a stay time offset.

[0153] For example, as a signaling optimization, the terminal supports delta reporting when sending updated mobility trajectory information. For instance, if the terminal's predicted path cell remains the same but the time has changed, the terminal can simply indicate the time offset.

[0154] It should be noted that "the community remains the same" means that the community information or location information is the same. "Changes in time" refers to different stay times or durations of stay.

[0155] For example, the aforementioned stay time information includes a stay timestamp or stay duration, and the aforementioned dwell time information includes a dwell timestamp or dwell duration.

[0156] Optionally, in this embodiment, the dwell time offset includes the dwell time offset of all cells or reference cells in the second movement trajectory information. The stay time offset also includes the stay time offset of all locations or reference locations in the second movement trajectory information.

[0157] For example, the terminal may indicate the time offset for each cell or each location; or the terminal may indicate the time offset for a reference cell or a reference location.

[0158] For example, the reference cell could be the first cell in the first or second movement trajectory information. The reference location could be the first location in the first or second movement trajectory information.

[0159] For example, the reference cell could be the last cell in either the first or second movement trajectory information. The reference location could be the last location in either the first or second movement trajectory information.

[0160] For example, the reference cell can be a cell specified in the first or second movement trajectory information. The reference location can be a location specified in the first or second movement trajectory information.

[0161] For example, when reporting the second movement trajectory information, the terminal can indicate the information of the reference cell to the network side, that is, indicate which cell(s) is the reference cell(s).

[0162] In this way, the terminal only reports the dwell time offset or residence time offset that is different from the first movement trajectory information in the second movement trajectory information, which can reduce the signaling overhead and improve the information transmission efficiency.

[0163] Optionally, in this embodiment of the application, the step 201 above, "the terminal initiating the first process or after the first process ends, instructs the network-side device to provide the first movement trajectory information", can be specifically implemented through the following step 201x.

[0164] Step 201x: When the terminal is in an RRC disconnected state, has first movement trajectory information, and the network-side device allows the terminal to report the first movement trajectory information, the terminal indicates the first movement trajectory information to the network-side device during the initiation of the first process or after the completion of the first process.

[0165] In this embodiment of the application, the network-side device can send configuration information to the terminal, which indicates whether the terminal is allowed to initiate the first process when it is in an RRC disconnected state and has first movement trajectory information.

[0166] In this way, controlling whether the terminal can report its movement trajectory information by the network-side equipment can improve the flexibility of the network side in obtaining the terminal's movement trajectory information.

[0167] Optionally, in this embodiment of the application, during the initiation of the first process or after the end of the first process, the terminal may indicate the first movement trajectory information to the network-side device through RRC messages or NAS messages.

[0168] For example, the aforementioned RRC message may be terminal assistance information, RRC reconfiguration complete message, terminal information response message, or RRC connection restoration complete message.

[0169] For example, the NAS message mentioned above can be a registration request message or a service request message.

[0170] Optionally, in the embodiments of this application, after step 201 above, the information reporting method provided in the embodiments of this application may further include the following steps 401 or 501.

[0171] Step 401: When the terminal indicates the first movement trajectory information to the network-side device via NAS message, the terminal receives a response from the network-side device.

[0172] In this embodiment of the application, the response may include information about the registration area.

[0173] For example, when the terminal is in RRC idle state and has first movement trajectory information, the terminal sends a NAS message or triggers a NAS procedure. The NAS message can be a registration request message, and the NAS procedure can be a registration update procedure. Furthermore, after triggering the registration update procedure, the terminal can report the first movement trajectory information during the registration update process, such as by carrying the first movement trajectory information through the registration request message. After receiving the registration request message, the network-side device can reply to the terminal with a registration acceptance message and reconfigure the registration area (such as a TAI list) in the registration acceptance message.

[0174] It should be noted that the above registration receiving message is the same as the above response, and the above registration area (such as TAI list) is the information of the above registration area.

[0175] Optionally, in this embodiment of the application, after step 401 above, the information reporting method provided in this embodiment of the application further includes step 402 as follows.

[0176] Step 402: When the terminal is in RRC idle state and the cell it is currently camped on does not belong to the registration area, the terminal determines whether to perform registration update based on whether the cell it is currently camped on matches the cell or location predicted in the first movement trajectory information.

[0177] Optionally, in this embodiment of the application, if the terminal is in the RRC idle state, the cell it is currently camped on does not belong to the registration area, and the cell it is currently camped on matches the cell or location predicted in the first movement trajectory information, the terminal does not perform registration update, or the terminal determines whether to perform registration update in this case according to the network side configuration.

[0178] It is understandable that the cell where the terminal is currently stationed matches the cell or location predicted in the first motion trajectory information, meaning that the cell or location where the terminal is currently stationed is the same as the cell or location in the first motion estimation information.

[0179] For example, after the terminal indicates its first movement trajectory information to the network-side device, it re-enters the RRC idle state and performs cell selection and reselection. If the cell selected by the terminal is not within its registered area but matches the movement trajectory information reported by the terminal (as expected), the terminal may not need to perform the mobile registration update procedure. Based on this, the network side can page the terminal based on its first movement trajectory information. Alternatively, if the cell selected by the terminal is not within its registered area but matches the movement trajectory information reported by the terminal (as expected), the terminal can determine whether to perform the mobile registration update procedure based on the network configuration information.

[0180] For example, the network-side device can send configuration information to the terminal, which indicates whether the terminal is allowed to perform the aforementioned mobile registration update process.

[0181] It should be noted that the cell the terminal reselects is the same cell it is currently using. The mobile trajectory information reported by the terminal indicates that the cell it is currently using matches the predicted cell or location of the terminal in the first mobile trajectory information. The mobile registration update process described above is the same as the registration update process described above.

[0182] Thus, if the terminal leaves the registered area but the cell it is currently residing in matches the first movement trajectory information, the terminal does not need to perform a registration update, and the network-side device can still page the terminal.

[0183] Optionally, in this embodiment of the application, if the terminal is in the RRC idle state, the cell it is currently camped on does not belong to the registration area, and the cell it is currently camped on does not match the cell or location predicted in the first movement trajectory information, the terminal performs a registration update.

[0184] It is understandable that the cell where the terminal is currently stationed does not match the cell or location predicted in the first motion trajectory information, meaning that the cell where the terminal is currently stationed is different from the cell in the first motion estimation information and the location is different.

[0185] For example, when the cell that the terminal reselects is neither in the terminal's registered area nor matches the movement trajectory reported by the terminal (i.e., inconsistent with expectations), the terminal needs to trigger the mobile registration update again.

[0186] It should be noted that the cell the terminal reselects is the same cell it is currently using. The aforementioned movement trajectory that does not match the terminal's reported movement trajectory means that the cell it is currently using does not match the cell or location predicted in the first movement trajectory information. The aforementioned mobile registration update process is the aforementioned registration update.

[0187] Optionally, in this embodiment of the application, when the terminal is in the RRC idle state, the cell currently camped is in the registration area, and the cell currently camped does not conform to the cell or location predicted in the first movement trajectory information, the terminal performs the first operation.

[0188] Optionally, in the embodiments of this application, the first operation described above may include any of the following:

[0189] The terminal performs a registration update and updates the first movement trajectory information;

[0190] The terminal does not perform registration updates;

[0191] The terminal determines whether to perform a registration update based on the network-side configuration.

[0192] For example, when the cell reselected by the terminal belongs to the terminal's registered area but does not match the movement trajectory reported by the terminal, the terminal's behavior may include any of the following:

[0193] The terminal performs a mobile registration update, updating its own movement trajectory;

[0194] The terminal does not perform mobile registration updates. The network can page the terminal within the registered area after failing to page it based on the mobile trajectory information reported by the terminal.

[0195] Whether a terminal performs a mobile registration update can be configured by the network side.

[0196] Step 501: When the terminal indicates the first movement trajectory information to the network-side device via an RRC message, the terminal receives a response from the network-side device.

[0197] In this embodiment of the application, the above response may include information about the RAN-based notification area (RNA).

[0198] For example, when the terminal is in an RRC inactive state and has first movement trajectory information, the terminal initiates an RRC connection restoration process. This RRC message can be an RRC connection restoration request message. The terminal can report the first movement trajectory information to the network-side device during or after the RRC connection restoration process. After receiving the first movement trajectory information reported by the terminal, the network-side device can reply to the terminal with a response, which includes RNA information.

[0199] Optionally, in this embodiment of the application, after step 501 above, the information reporting method provided in this embodiment of the application further includes the following step 502.

[0200] Step 502: When the terminal is in RRC inactive state and the cell currently camped is not in the RAN notification area, the terminal determines whether to execute the RAN-based notification area update (RNAU) procedure based on whether the cell currently camped matches the cell or location predicted in the first movement trajectory information.

[0201] Optionally, in this embodiment of the application, if the terminal is in an RRC inactive state, the cell it is currently camped on does not belong to the RAN notification area, and the cell it is currently camped on matches the cell or location predicted in the first movement trajectory information, the terminal does not perform RAN notification area update, or the terminal determines whether to perform RAN notification area update in this case according to the network side configuration.

[0202] For example, after the terminal indicates its first movement trajectory information to the network-side device, it re-enters the RRC idle state and performs cell selection and reselection. If the cell selected by the terminal is not within the terminal's RAN notification area but matches the movement trajectory information reported by the terminal (as expected), the terminal may not execute the RAN notification area update procedure. Based on this, the network side can page the terminal based on its first movement trajectory information. Alternatively, if the cell selected by the terminal is not within its RAN notification area but matches the movement trajectory information reported by the terminal (as expected), the terminal can determine whether to execute the RAN notification area update procedure based on the network's configuration information.

[0203] For example, network-side devices can send configuration information to terminals, which indicates whether the terminals are allowed to execute the aforementioned RAN notification area update procedure.

[0204] It should be noted that the cell that the terminal reselects is the same cell that it is currently using. The mobile trajectory information reported by the terminal is the same cell that the terminal is currently using, which is predicted in the first mobile trajectory information as the cell or location where the terminal is currently using.

[0205] Thus, if the terminal leaves the RAN notification area but the cell it is currently camped in matches the first movement trajectory information, the terminal does not need to perform the RAN notification area update, and the network-side equipment can still page the terminal.

[0206] Optionally, in this embodiment of the application, when the terminal is in the RRC idle state, the cell currently camped does not belong to the RAN notification area, and the cell currently camped does not conform to the cell or location predicted in the first movement trajectory information where the terminal is currently camped, the terminal performs RAN notification area update.

[0207] For example, when the cell that the terminal reselects is neither in the terminal's RAN notification area nor in line with the movement trajectory reported by the terminal (i.e., inconsistent with expectations), the terminal needs to trigger the RAN notification area update again.

[0208] It should be noted that the cell that the terminal reselects is the same cell that it is currently using. The aforementioned movement trajectory that does not match the terminal's reported movement trajectory means that the cell it is currently using does not match the cell or location predicted in the first movement trajectory information.

[0209] Optionally, in this embodiment of the application, when the terminal is in the RRC idle state, the cell currently camped is in the RAN notification area, and the cell currently camped does not conform to the cell or location predicted in the first movement trajectory information, the terminal performs the second operation.

[0210] Optionally, in embodiments of this application, the second operation described above may include any of the following:

[0211] The terminal performs a RAN notification area update and updates the first movement trajectory information;

[0212] The terminal does not perform RAN notification area update;

[0213] The terminal determines whether to perform RAN notification area update based on the network-side configuration.

[0214] For example, when the cell reselected by the terminal belongs to the terminal's RAN notification area but does not match the movement trajectory reported by the terminal, the terminal's behavior may include any of the following:

[0215] The terminal performs a RAN notification area update to update its own movement trajectory.

[0216] The terminal does not perform RAN notification area updates. The network side can attempt to page the terminal in the RAN notification area after failing to do so based on the terminal's reported mobility trajectory information.

[0217] Whether the terminal performs RAN notification area update can be configured by the network side.

[0218] Optionally, in this embodiment of the application, the "terminal initiates the first process" in step 201 above can be implemented by step 201c below.

[0219] Step 201c: When the terminal is in an RRC inactive state and has the first movement trajectory information, the terminal sends an RRC connection restoration request message to the network-side device.

[0220] In this embodiment of the application, the RRC connection recovery request message carries recovery reason information, which may include at least one of the following:

[0221] RNAU;

[0222] The terminal needs to report the first movement trajectory information.

[0223] Optionally, in this embodiment of the application, when the terminal has the first movement trajectory information while it is in the RRC inactive state, the terminal triggers the RRC connection recovery process, and can indicate to the network side that the reason for the recovery is RNAU or the terminal reporting movement trajectory information when requesting the recovery of the RRC connection.

[0224] For example, the terminal can indicate the reason for the recovery by a specific recovery reason value in the RRC connection recovery request message, or by a specific logical channel identifier (LCID) field, etc.

[0225] Thus, the terminal carries the recovery reason information in the RRC connection recovery request message to inform the network-side device that this request for RRC connection recovery is related to the reporting of movement trajectory information. The network-side device then determines whether to accept the terminal's connection recovery request, and if accepted, can request movement trajectory information from the terminal in the RRC connection recovery message as soon as possible.

[0226] Optionally, in this embodiment of the application, the step 201 above, "the terminal initiating the first process or after the first process ends, instructs the network-side device on the first movement trajectory information", can be specifically implemented through the following steps 201e and 201f.

[0227] Step 201e: The terminal receives an RRC connection recovery message from the network-side device.

[0228] In this embodiment of the application, the RRC connection restoration message carries second indication information, which instructs or requests the terminal to report movement trajectory information.

[0229] Step 201f: The terminal sends an RRC connection restoration complete message to the network-side device.

[0230] In this embodiment of the application, the RRC connection restoration completion message carries the first movement trajectory information.

[0231] Optionally, in this embodiment of the application, the reporting of the first movement trajectory information may include the following methods:

[0232] Method 1: After the terminal sends the RRC connection restoration request message, the terminal receives an RRC connection restoration message, which instructs or requests the terminal to report movement trajectory information. Subsequently, the terminal includes the movement trajectory information in the RRC connection restoration completion message.

[0233] Method 2: After the terminal resumes RRC connection and enters RRC connection state, the network side requests the terminal to report the terminal's movement trajectory information in the UE information response message through the UE information request message.

[0234] Method 3: After the terminal resumes the RRC connection and enters the RRC connection state, the terminal reports the movement trajectory information through UE Assistance Information (UAI).

[0235] Optionally, in this embodiment, the network-side device can store the terminal's predicted movement trajectory information during the terminal's RRC disconnected state. Considering that updating and reporting movement trajectory information during this period may be optional, when the terminal is in the process of establishing or restoring an RRC connection or entering the RRC connected state, if the terminal's movement trajectory information is still valid compared to the last reported movement trajectory information, then the base station can directly obtain the last reported movement trajectory information from the core network device without needing to perform prediction again (the purpose of prediction is for mobility management in the connected state).

[0236] Optionally, in this embodiment of the application, during the establishment or restoration of the RRC connection or after entering the RRC connection state, the terminal may send a third indication information to the network-side device. The third indication information is used to indicate the validity of the aforementioned first movement trajectory information.

[0237] Optionally, in this embodiment of the application, the terminal may carry the aforementioned third indication information in the msg5 message.

[0238] Optionally, in this embodiment, the network-side device may also configure validity verification conditions to be sent to the terminal, and the terminal may verify the validity of the first movement trajectory information according to the validity verification conditions. For example, the validity verification conditions may be configured by the base station through an RRC connection release message and sent to the terminal.

[0239] Thus, if the network-side device stores the predicted movement trajectory information of the terminal during the RRC disconnected state, and if the RRC connection is established or restored or the terminal is in the RRC connected state, the network side will not make a prediction if the third indication information from the terminal indicates that the previously reported movement trajectory information of the terminal is valid. Instead, it will directly use the previously reported movement trajectory information of the terminal for paging, which can reduce the network energy consumption caused by prediction calculation.

[0240] The information reporting method provided in this application embodiment, compared to related technologies, only triggers mobile trajectory information reporting when the network-side device has predicted mobile trajectory information and the terminal is currently in RRC connected state. It cannot promptly obtain the terminal's predicted mobile trajectory information when the terminal is in RRC disconnected state and has predicted mobile trajectory information. In this solution, when the terminal is in RRC disconnected state and has predicted mobile trajectory information, the terminal initiates a first process and, during or after initiating the first process, indicates its mobile trajectory information to the network-side device. This achieves the goal of quickly entering RRC connected state and reporting its mobile trajectory information to the network-side device. This allows the network-side device to know the terminal's mobile trajectory information, and based on this information, when the terminal's downlink service arrives, the network-side device can estimate the cell or location the terminal might be camped at that moment, thereby notifying the corresponding base station to paging the terminal and reducing paging overhead. In addition, the movement trajectory information can be sent to the base station by the core network equipment, so that the base station can estimate the approximate time for the terminal to reselect to the local cell, thereby enabling the transmission of system information and reducing the power consumption and latency caused by the terminal sending wake-up signals in multiple energy-saving cells.

[0241] Figure 3 A flowchart illustrating the information reporting method provided in an embodiment of this application is shown. Figure 3 As shown, the information reporting method provided in this application embodiment may include the following steps 601 to 604.

[0242] Step 601: The network-side device sends configuration information to the terminal.

[0243] In this embodiment, the configuration information is used to instruct the terminal to display the first movement trajectory information when it is in an RRC disconnected state and has the first movement trajectory information. Optionally, in this embodiment, to avoid frequent registration updates caused by the terminal frequently changing its movement trajectory, the network-side device can send configuration information to the terminal to instruct it to report movement trajectory information, and only then can the terminal report movement trajectory information to the network-side device.

[0244] For example, the above configuration information can be used to indicate whether the terminal is allowed to report movement trajectory information; or, the above configuration information can be used to indicate whether the terminal is allowed to report updated movement trajectory information; or, the above configuration information can also be a preset threshold, used to indicate that the terminal reports movement trajectory information when the preset threshold is met.

[0245] Step 602: The terminal receives configuration information from the network-side device.

[0246] Step 603: The terminal sends the first message to the network-side device.

[0247] In this embodiment of the application, the first message is used to indicate the first movement trajectory information possessed by the terminal. The first message is either a message during the initiation of the first process or a message after the completion of the first process.

[0248] In this embodiment, when the terminal is in RRC idle state, the first process described above is an RRC connection establishment process. When the terminal is in RRC inactive state, the first process described above is an RRC connection recovery process or an SDT process.

[0249] For example, the first message mentioned above could be a message from the RRC connection recovery process, such as the RRC connection recovery complete message mentioned above. Alternatively, the first message mentioned above could be a message from the RRC connection establishment process, such as the registration request message mentioned above.

[0250] Step 604: The network-side device receives the first message from the terminal.

[0251] Optionally, in this embodiment of the application, the first movement trajectory information includes at least one of the following:

[0252] The terminal predicts the identification information of at least one cell where it will be camped;

[0253] The terminal's predicted dwell time stamp in at least one cell;

[0254] The terminal's predicted dwell time in at least one cell.

[0255] Optionally, in this embodiment of the application, the first movement trajectory information includes at least one of the following:

[0256] At least one location information predicted by the terminal;

[0257] The terminal predicts the dwell time stamp corresponding to at least one location information;

[0258] The terminal predicts the dwell time at at least one location.

[0259] Optionally, in the embodiments of this application, step 602 can be implemented by step 602a or step 602b as described below.

[0260] Step 602a: The network-side device receives the first movement trajectory information from the terminal.

[0261] In this embodiment of the application, the aforementioned first movement trajectory information had not been reported before.

[0262] Step 602b: The network-side device receives the first instruction information from the terminal.

[0263] In this embodiment of the application, the first indication information indicates that the first movement trajectory information has been restored to a valid state. The first movement trajectory information was previously reported and was in an invalid state.

[0264] Optionally, in this embodiment of the application, after step 602 above, the information reporting method provided in this embodiment of the application may further include at least one of the following steps 603 and 605.

[0265] Step 603: The network-side device receives the second message from the terminal.

[0266] In this embodiment of the application, the second message is used to indicate the updated first movement trajectory information, and the second message includes a dwell time offset or a stay time offset.

[0267] For example, after receiving configuration information from the network-side device, the terminal can know that the network-side device allows the terminal to report movement trajectory information. Therefore, if the terminal determines that the first movement trajectory information has been updated, it can send the aforementioned second message to the network-side device.

[0268] Step 605: The network-side device receives a third message from the terminal.

[0269] In this embodiment of the application, the aforementioned third message is used to indicate that the first movement trajectory information is invalid.

[0270] Optionally, in this embodiment of the application, after step 603 above, the information reporting method provided in this embodiment of the application may further include step 61 or step 62 below.

[0271] Step 61: The network-side device determines the second movement trajectory information based on the first movement trajectory information and the dwell time offset.

[0272] Optionally, in this embodiment of the application, the second movement trajectory information is an updated first movement trajectory information.

[0273] For example, if the dwell time offset includes the dwell time offset of each cell in the first movement trajectory information, the network-side device can update the dwell timestamp or dwell duration in each cell in the first movement trajectory information according to the dwell time offset to obtain the second movement trajectory information.

[0274] For example, when the dwell time offset includes the dwell time offset of the first cell in the first movement trajectory information, the network-side device can update the dwell timestamp or dwell time in the first cell according to the dwell time offset of the first cell, and then determine the updated dwell timestamp in the second cell according to the updated dwell time in the first cell, and so on, so that the dwell timestamp in each cell can be updated to finally obtain the second movement trajectory information.

[0275] Step 62: The network-side device determines the second movement trajectory information based on the first movement trajectory information and the dwell time offset.

[0276] It should be noted that the implementation method of this step is the same as that of step 61 above, and this step will not be described again here.

[0277] Optionally, in this embodiment, the first message is a NAS message or an RRC message. After step 602 above, the information reporting method provided in this embodiment may further include step 607 or step 608 as described below.

[0278] Step 607: If the first message is a NAS message, the network-side device sends a response to the terminal in response to the NAS message.

[0279] In this embodiment of the application, the above response includes information about the registration area.

[0280] Step 608: If the first message is an RRC message, the network-side device sends a response to the terminal in response to the RRC message.

[0281] In this embodiment of the application, the above response includes information about the RAN notification area.

[0282] Optionally, in this embodiment of the application, before step 602 above, the information reporting method provided in this embodiment of the application further includes step 602e below. Correspondingly, step 602 above can be implemented by step 602f below.

[0283] Step 602e: The network-side device sends an RRC connection recovery message to the terminal.

[0284] In this embodiment of the application, the aforementioned RRC connection recovery message is used to instruct or request the terminal to report movement trajectory information.

[0285] Step 602f: The network-side device receives an RRC connection restoration complete message from the terminal.

[0286] In this embodiment of the application, the RRC connection restoration completion message carries the first movement trajectory information.

[0287] Optionally, in this embodiment of the application, before step 602e above, the information reporting method provided in this embodiment of the application further includes step 602d below.

[0288] Step 602d: The network-side device receives an RRC connection recovery request message from the terminal.

[0289] In this embodiment of the application, the RRC connection recovery request message carries recovery reason information, which includes at least one of the following:

[0290] RNAU;

[0291] The terminal needs to report the first movement trajectory information.

[0292] The information reporting method provided in this application embodiment allows the terminal to quickly enter the RRC connected state when it is in an RRC disconnected state. The terminal then promptly reports the predicted movement trajectory information to the network-side device. The network-side device receives the terminal's movement trajectory information from a first message received from the terminal. Based on this movement trajectory information, when the terminal's downlink service arrives, the network-side device can estimate the cell or location the terminal might be camped at that moment, thereby notifying the corresponding base station to perform targeted paging of the terminal, thus reducing paging overhead. Furthermore, the aforementioned first movement trajectory information can be sent to the base station by the core network device. This allows the base station to estimate the approximate time it will take for the terminal to reselect to its current cell, thereby enabling the transmission of system information and reducing the power consumption and latency caused by the terminal sending wake-up signals in multiple energy-efficient cells.

[0293] It should be noted that the specific implementation of the steps in this embodiment is the same as the specific implementation of the relevant steps in the above embodiments. For the parts not described in detail in this embodiment, please refer to the relevant descriptions in the above embodiments. This embodiment will not repeat them here.

[0294] It should be noted that for terminals with relatively fixed movement trajectories over time, improvements can be made to the existing recording behavior of historical movement information. Figure 4 A flowchart illustrating the information reporting method provided in an embodiment of this application is shown. Figure 4As shown, the information reporting method provided in this application embodiment may include the following steps 701 and 702.

[0295] Step 701: When the terminal is in RRC connection state, the terminal sends its historical mobility information to the network-side device.

[0296] In this embodiment of the application, the aforementioned historical mobility information includes the identification information of at least one historical cell and the dwell timestamp of the terminal in at least one historical cell.

[0297] For example, the aforementioned historical cell may be a historical serving cell or a historical residing cell, and the aforementioned residing timestamp may be an absolute timestamp, such as Universal Time Coordinated (UTC).

[0298] For example, regardless of the RRC state in which the terminal is, the terminal can record its historical movement information and send the historical movement information to the network-side device when the terminal enters the RRC connected state.

[0299] Optionally, in this embodiment of the application, the historical movement information further includes at least one of the following:

[0300] The duration of terminal dwell time in at least one historical cell;

[0301] The number of times the terminal has stayed in at least one historical cell.

[0302] For example, the dwell time of the terminal in at least one historical cell may include the dwell time of the terminal in at least one historical serving cell or historical stationed cell. The number of times the terminal dwells in at least one historical cell may include the number of times the terminal dwells in at least one historical serving cell or historical stationed cell.

[0303] Optionally, in this embodiment of the application, at least one historical cell includes at least one of the following:

[0304] The cell configured by the network-side device when releasing the RRC connection;

[0305] The cell where the terminal has historically resided indicates the cell where the terminal has recorded historical mobility information;

[0306] The cell is determined based on specific rules, which are related to the network's energy-saving status.

[0307] Optionally, in the embodiments of this application, the specific rules mentioned above include any one of the following:

[0308] The residential community is a network-efficient community;

[0309] The cell in which the terminal sent a wake-up signal while it was camped on the cell.

[0310] For example, to reduce the impact on the terminal, the terminal may only record timestamp information in a specific cell. The specific cell may be a network-configured cell (instructed by dedicated signaling or broadcast instructions from the currently camped cell), or a cell determined based on specific rules. For example, when the terminal camps in a network energy saving (NES) cell or a cell that has sent a wake-up signal, the terminal may record timestamp information in that cell.

[0311] It should be noted that the timestamp information mentioned above is the same as the dwell timestamp mentioned above. The cell currently dwelling in the broadcast indicates the cell recorded by the terminal, which refers to the cell where the terminal has historically dwelled and the cell where the terminal records historical movement information.

[0312] Thus, when the terminal is in the RRC connected state, it reports historical mobility information to the network-side device. Since the historical mobility information includes the timestamp of the terminal's stay in at least one historical cell, the network-side device can know the historical cells where the terminal stayed at different times. Therefore, even if the terminal is released to the RRC disconnected state, the network-side device can predict the terminal's movement trajectory based on the historical mobility information.

[0313] Step 702: The network-side device receives historical mobility information from the terminal.

[0314] In this embodiment of the application, the aforementioned historical mobility information may include the identification information of at least one historical cell and the dwell timestamp of the terminal in at least one historical cell.

[0315] Optionally, in this embodiment of the application, the network-side device can be an access network device. For example, in combination with... Figure 4 ,like Figure 5 As shown, after step 702 above, the information reporting method provided in this application embodiment may further include the following step 703.

[0316] Step 703: The access network device sends historical mobility information to the core network device.

[0317] For example, the base station sends the historical mobility information reported by the terminal to core network elements, such as AMF, OAM, NWDAF, etc. for storage.

[0318] Optionally, in the embodiments of this application, step 703 above can be implemented by step 703a below.

[0319] Step 703a: When the core network device requests or subscribes to historical mobility information, the access network device sends historical mobility information to the core network device.

[0320] For example, a base station may send historical mobility information to a core network element when the core network element requests or subscribes to historical mobility information.

[0321] In this way, based on the historical mobility information reported by the terminal, the base station can predict the probability that the terminal will stay in certain cells during certain time periods in the RRC non-connectivity state, thereby optimizing the network.

[0322] The information reporting method provided in this application embodiment allows a terminal to report historical mobility information to the network-side device when it is in RRC connected state. Since the historical mobility information includes the terminal's dwell timestamps in at least one historical cell, the network-side device can determine the historical cells the terminal has been in at different times. Therefore, even if the terminal is released to RRC disconnected state, the network-side device can predict the terminal's movement trajectory based on the historical mobility information. When the terminal's downlink service arrives, the network-side device can estimate the cell or location the terminal may be in at that time, thereby notifying the corresponding base station to perform targeted paging of the terminal, thus reducing paging overhead.

[0323] It should be noted that before the RRC connection is released, the network-side device can obtain the terminal's predicted movement trajectory information and use it after the RRC connection is released. Figure 6 A flowchart illustrating the information reporting method provided in an embodiment of this application is shown. Figure 6 As shown, the information reporting method provided in this application embodiment may include the following steps 801 and 802.

[0324] Step 801: When the terminal is in RRC connection state and has third movement trajectory information, the terminal sends the third movement trajectory information to the network side device.

[0325] In this embodiment of the application, the aforementioned third movement trajectory information is used to determine the position of the terminal during the RRC non-connected state.

[0326] It is understandable that the network-side equipment stores the third movement trajectory information sent by the terminal when it is in the RRC connected state. When the terminal is in the RRC disconnected state, the network-side equipment can use the third movement trajectory information to predict the current location of the terminal, thereby realizing directional paging and optimizing the transmission of base station public signals.

[0327] Furthermore, the aforementioned third movement trajectory can also be used to determine the terminal's location information during the RRC connected state.

[0328] Optionally, in this embodiment of the application, the aforementioned third movement trajectory information may include at least one of the following:

[0329] The terminal predicts the identification information of at least one cell where it will reside;

[0330] The terminal's predicted dwell timestamp in the at least one cell;

[0331] The terminal predicts the dwell time in the at least one cell.

[0332] Optionally, in this embodiment of the application, the aforementioned third movement trajectory information includes at least one of the following:

[0333] The terminal predicts at least one location information;

[0334] The terminal predicts the dwell timestamp corresponding to the at least one location information;

[0335] The terminal predicts the dwell time corresponding to the at least one location information.

[0336] For example, when the terminal is in RRC connected state, it can report the predicted third movement trajectory information through RRC messages or NAS messages.

[0337] Optionally, in this embodiment of the application, the terminal may send the aforementioned third movement trajectory information to the network-side device upon receiving a request from the network side.

[0338] In this embodiment of the application, when the terminal's RRC connection is released, the terminal does not delete the aforementioned third movement trajectory information.

[0339] Step 802: The network-side device receives third-party movement trajectory information from the terminal.

[0340] In this embodiment of the application, the aforementioned third movement trajectory information is used by the network-side device to determine the location of the terminal during the RRC non-connected state.

[0341] Optionally, in this embodiment of the application, the aforementioned network-side device can be an access network device. Combined with... Figure 6 ,like Figure 7 As shown, after step 802 above, the information reporting method provided in this application embodiment may further include step 803 below.

[0342] Step 803: The access network device sends the third movement trajectory information to the core network device.

[0343] For example, when a terminal reports the predicted third movement trajectory information to the base station via an RRC message, the base station can send the third movement trajectory information reported by the terminal to core network elements such as AMF, OAM, and NWDAF for storage.

[0344] Optionally, in the embodiments of this application, step 803 above can be implemented by step 803a below.

[0345] Step 803a: When the core network device requests or subscribes to the mobility trajectory information, the access network device sends the third mobility trajectory information to the core network device.

[0346] For example, when the core network requests or subscribes to the mobile trajectory information, the base station sends the third mobile trajectory information to the core network element.

[0347] Optionally, in this embodiment of the application, when the terminal is in an RRC non-connected state, the information reporting method provided in this embodiment of the application further includes the following steps 901 or 902.

[0348] Step 901: When the terminal is in an RRC disconnected state, has first movement trajectory information, and the first movement trajectory information is different from the third movement trajectory information, the terminal initiates a first process, and during the initiation of the first process or after the completion of the first process, it indicates the first movement trajectory information to the network-side device.

[0349] When the terminal is in RRC idle state, the first process is the RRC connection establishment process; when the terminal is in RRC inactive state, the first process is the RRC connection recovery process or the SDT process.

[0350] Step 902: When the terminal is in RRC disconnected state and the third movement trajectory information is invalid, the terminal initiates the first process and, during the initiation of the first process or after the completion of the first process, indicates to the network-side device that the third movement trajectory information is invalid.

[0351] When the terminal is in RRC idle state, the first process is the RRC connection establishment process; when the terminal is in RRC inactive state, the first process is the RRC connection recovery process or the SDT process.

[0352] It should be noted that the implementation process of the terminal initiating the first process in steps 901 and 902 above, and indicating the first movement trajectory information to the network-side device during or after the initiation of the first process, is the same as the implementation process in the above embodiments. For the parts not specifically described in steps 901 and 902, please refer to the relevant descriptions in the above embodiments. This embodiment will not repeat them here.

[0353] Optionally, in this embodiment of the application, after step 802 above, the information reporting method provided in this embodiment of the application further includes the following step 805.

[0354] Step 805: The network-side device receives the fourth message from the terminal.

[0355] In this embodiment of the application, the fourth message is used to indicate the first movement trajectory information possessed by the terminal, or the fourth message is used to indicate that the third movement trajectory information has failed.

[0356] In this embodiment of the application, the aforementioned fourth message is a message in the RRC connection establishment process, or a message in the RRC connection recovery process or the SDT process. For example, the aforementioned fourth message is a registration request message in the RRC connection establishment process, or an RRC connection recovery completion message in the RRC connection recovery process.

[0357] The information reporting method provided in this application embodiment, when the terminal is in RRC connected state and has third movement trajectory information, sends the third movement trajectory information to the network-side device. The network-side device can determine the terminal's location during the RRC disconnected state based on the third movement trajectory information. After the terminal is released to the RRC disconnected state by the network side, the first procedure is not initiated immediately. Instead, it is determined whether the third movement trajectory information reported in the RRC connected state is the same as the terminal's current first movement trajectory information. If so, the third movement trajectory information is used, and the base station can estimate the approximate time for the terminal to reselect to the local cell, thereby initiating the transmission of system information and reducing the power consumption and latency caused by the terminal sending wake-up signals in multiple energy-saving cells. If not, the terminal initiates the first procedure to re-report the first movement trajectory information. When the terminal's downlink service arrives, even if the terminal is in the RRC disconnected state, the network-side device can estimate the cell or location where the terminal may be camped at that moment, thereby notifying the corresponding base station to page the terminal in a targeted manner, achieving the purpose of reducing paging overhead.

[0358] It should be noted that the specific implementation of some steps in this embodiment is the same as the specific implementation of the relevant steps in the above embodiments. For the parts not described in detail in this embodiment, please refer to the relevant descriptions in the above embodiments. This embodiment will not repeat them here.

[0359] It should be noted that each of the above method embodiments, or various possible implementations of each method embodiment, can be executed individually or in combination of any two or more. The specific implementation can be determined according to actual usage requirements, and this application embodiment does not impose any restrictions on this.

[0360] The information reporting method provided in this application can be executed by an information reporting device. This application uses an information reporting device executing the information reporting method as an example to illustrate the information reporting device provided in this application.

[0361] This application provides an information reporting device. As an example, the information reporting device can be a communication device or a component within a communication device, such as a chip. The communication device can be a terminal, a network-side device, or a server, etc. Exemplarily, the terminal can be, but is not limited to, the type of terminal 11 listed above, and the network-side device can be, but is not limited to, the type of network-side device 12 listed above. This application does not impose specific limitations.

[0362] The information reporting device includes a receiving module, a transmitting module, and a processing module. These modules can be implemented in software or hardware.

For example, the processor can include general-purpose processors, special-purpose processors, such as a Central Processing Unit (CPU), microprocessor, Digital Signal Processor (DSP), Artificial Intelligence (AI) processor, Graphics Processing Unit (GPU), Application Specific Integrated Circuit (ASIC), Network Processor (NP), Field Programmable Gate Array (FPGA), or other programmable logic devices, gate circuits, transistors, discrete hardware components, etc. The receiving and transmitting modules can be implemented by a communication interface, which can include one or more of the following: transceiver, pins, circuits, bus, radio frequency unit, etc.

[0363] For details, see Figure 8 When the information reporting device is a terminal or a component in a terminal, the information reporting device 80 includes a processing module 81.

[0364] The aforementioned processing module 81 is used to initiate a first process when the terminal is in an RRC disconnected state and has first movement trajectory information, and to indicate the first movement trajectory information to the network-side device during the initiation of the first process or after the completion of the first process; wherein, when the RRC disconnected state includes the RRC idle state, the aforementioned first process is an RRC connection establishment process; when the RRC disconnected state includes the RRC inactive state, the aforementioned first process is an RRC connection recovery process or an SDT process.

[0380] Optionally, in this embodiment of the application, the above-mentioned processing module 81 is specifically used to send the first movement trajectory information to the network-side device when the terminal has not reported the first movement trajectory information during the initiation of the first process or after the end of the first process; or, when the terminal has previously reported the first movement trajectory information and the first movement trajectory information is in an invalid state during the initiation of the first process or after the end of the first process, the first indication information sends the first indication information to the network-side device, the first indication information indicating that the first movement trajectory information is restored to a valid state.
