[0057] Some concepts or terms or related technologies involved in the information reporting method, terminal and network side device provided by the embodiments of the present application are explained as follows.

[0058] 1. UAV flight path information reporting

[0059] An unmanned aerial vehicle (UAV) usually has a determined flight trajectory when flying. The UAV reports the flight trajectory information to the network side when in an RRC connected state, and the network can perform RRC connected state mobility management, such as handover preparation, based on the information. Therefore, the UAV flight trajectory information (flight path info) reporting mechanism is introduced in both LTE and NR protocols.

[0060] Specifically, when the terminal has flight trajectory information, the terminal can first indicate to the network side that it has valid flight trajectory in the RRC connection establishment complete message, the RRC connection recovery complete message, the RRC connection reestablishment complete message, the RRC reconfiguration complete message, and the terminal assistance information (only supported in NR). Then, if the network side is interested in the flight trajectory of the terminal, the network side can request the terminal through the UE Information Request message, and then the terminal can report its flight path info through the UE Information Response message. The flight path info includes the passing points of the planned path and the corresponding estimated arrival time. In NR, in order to reduce the signaling overhead caused by reporting, some time / distance thresholds are also introduced to control the terminal to report only when the flight trajectory changes greatly.

[0061] The flight path info information can also be forwarded to the target base station by the source base station in the handover process. The flight trajectory 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 state or the RRC inactive state, the terminal assumes that the previously reported information will be released by the base station.

[0062] 2. Registration update

[0063] A user wants to get the services provided by the network must first register with the network. When the terminal registers with the network side, the AMF will allocate a registration area to the terminal, including a series of tracking areas, which is given by the tracking area identity list (TAI list). After that, the AMF will only page the terminal in the registration area. The TAI is composed of the mobile country code (MCC), the mobile network code (MNC), and the 3-byte tracking area code (TAC).

[0064] Once registered, the terminal needs to perform registration update according to the conditions defined in the standard:

[0065] Periodic registration update: when the periodic timer expires, the terminal performs periodic registration update procedure.

[0066] Mobility registration update (MRU): when the terminal leaves the current registration area, the terminal performs MRU. The registration area of the terminal is a TAI list, and when the TAI of the serving cell does not belong to the TAI list of the terminal, the terminal judges that it has left the current registration area.

[0067] When the terminal wants to update the capability information or re-negotiate the protocol parameters with the network side, the MRU procedure is triggered.

[0068] 3, Terminal location information transfer of N2 interface

[0069] The N2 interface supports the transfer of user location information (User Location Information) from the base station to the AMF, that is, the core network can subscribe to the serving cell information of the terminal (such as the TAI and cell where it is located each time the RRC connection is initiated) from the base station. The core network can collect such information to obtain the mobile trajectory of the terminal.

[0070] 4, Terminal mobile trajectory reporting

[0071] LTE and NR introduce the following mechanism: the terminal records its own historical mobile information (such as historical service cell / historical camped cell, service duration / camped duration) in the RRC idle / inactive / connected state. In the process of entering the connected state (such as RRC connection establishment complete message, RRC connection resume complete message), it can indicate to the network side that it has historical mobile information. If the network side is interested, the network side can request the terminal to report the historical mobile information.

[0072] The terminal will delete the local historical mobility information only when the terminal is deregistered in the core network. The base station can send the historical mobility information reported by the terminal to the core network or network elements such as operations administration and maintenance (OAM) for storage. When the terminal initiates RRC connection in a subsequent service cell and enters the connected state, the current service base station can obtain the historical mobility information of the terminal from the above network element, and based on the current location of the terminal, predict the staying time of the terminal at the current location or the next service cell of the terminal to prepare for handover. In addition, the historical mobility information of the terminal can also be exchanged on the Xn interface during the handover preparation process.

[0073] 5. AI-based terminal trajectory prediction

[0074] The standard introduces that the base station predicts the trajectory information of the terminal in the RRC connected state based on AI, that is, predicts the future service cell identity (ID) and the corresponding expected service duration. The predicted trajectory information can be used for network to select the target cell.

[0075] 6. Network energy saving

[0076] With the development of mobile communication technology, the fifth generation mobile communication base station has entered the stage of large-scale deployment. Although the fifth generation mobile communication base station can provide more powerful communication services, the high energy consumption that comes with it has greatly increased the operating costs of mobile operators. How to reduce the energy consumption of the fifth generation mobile communication base station has become a problem that operators need to solve. Most of the power consumption of the 5G network comes from the base station, and 90% of the power consumption of the NR base station comes from the active antenna unit (AAU). Due to higher frequency bands, wider bandwidths, more transceivers (TRX), and other reasons, the power consumption of a single NR base station is currently 3-4 times higher than that of LTE. In addition, in terms of operating costs (OPEX), the electricity bill of the base station accounts for nearly 20% of the entire network operating costs. For some operators, the electricity bill is more than half of the total profit. Therefore, network energy saving of NR has become more critical to achieve the great success of 5G. According to the actual load condition, the base station can implement different degrees of energy saving measures, such as shutting down the base station, shutting down the carrier / cell, shutting down the channel, shutting down the single sideband communication (SSB) / beam, shutting down the antenna / panel, cell discontinuous transmission (cell DTX) and / or discontinuous reception (cell DRX), channel state information (CSI) adaptation, on-demand request of system information block type 1 (SIB1), on-demand request of SSB, on-demand request of open system interconnect (OSI), and the like.

[0077] 7. In the case that there is no data transmission in the terminal, the network often releases the RRC connection of the terminal, and lets the terminal be in the RRC idle / inactive state. This can reduce the switching signaling overhead of the terminal in high-speed movement with 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).

[0078] 8、In order to ensure that the terminal can start service at any time, the terminal needs to perform cell selection and reselection based on the system message and synchronization signal sent by the network side in the RRC non-connected state, and camp on the cell with signal quality meeting the condition. When the service arrives at the network side, the network needs to page the terminal in all base stations in the entire registration area / RAN notification area. When the uplink service appears, the terminal initiates access in the currently camped cell.

[0079] The information reporting method, terminal and network side device provided by the embodiments of the present application will be described in detail below in combination with the drawings and some embodiments and application scenarios.

[0080] In the related art, the moving track of the terminal is often predictable, and the network can optimize the communication process, such as handover preparation and ping-pong handover avoidance, based on the predicted moving track of the terminal. In the related art, the prediction methods are as follows:

[0081] a. The network predicts the moving track of the terminal based on the deployment situation and geographical environment (such as high-speed rail environment);

[0082] b. For the situation that the network cannot predict, the terminal can record its own historical moving track and report it to the network side, and the network side can predict the subsequent moving track of the terminal in combination with the historical moving track of the terminal and the serving cell when the terminal is in the RRC connected state;

[0083] c. The terminal (such as UAV) has a planned path, so it has a predictable moving track. The terminal reports the planned moving track to the network side.

[0084] In the related art, the network side only predicts the moving track of the terminal when the terminal is in the RRC connected state, or obtains the predicted moving track of the terminal from the terminal, the purpose being to perform mobility management in the RRC connected state. In fact, the moving track of the terminal has regularity regardless of the RRC state of the terminal, and the terminal in the RRC idle / inactive state can also have a predictable moving track, which is helpful for the network side to implement directional paging, optimize the sending of synchronization signal and system information, and thus improve the network energy efficiency. However, the network side cannot know whether the terminal in the RRC idle / inactive state has the moving track information, nor can it effectively predict the moving track of the terminal during the RRC idle / inactive state.

[0085] That is, the network side cannot obtain the mobile trajectory information of the terminal in the RRC idle / inactive state, and cannot effectively predict the mobile trajectory of the terminal during the RRC idle / inactive state, so that the network cannot realize directional paging, and cannot optimize the transmission of the base station public signal, resulting in low network energy efficiency. For the terminal, the power consumption caused by the terminal frequently requesting the network energy-saving cell to transmit system information during the mobile process in the RRC non-connected state cannot be reduced.

[0086] To this end, an embodiment of the present application provides an information reporting method. In the case that a terminal is in an RRC non-connected state and has first mobile trajectory information, the terminal initiates a first process, and indicates the first mobile trajectory information to a network side device during the process of initiating the first process or after the first process ends. In the case that the terminal is in an RRC idle state, the first process is an RRC connection establishment process. In the case that the terminal is in an RRC inactive state, the first process is an RRC connection recovery process or an SDT process. Compared with the related art in which the network side device can only obtain the predicted mobile trajectory information of the terminal in the case that the terminal has the predicted mobile trajectory information and is currently in an RRC connected state, and cannot obtain the predicted mobile trajectory information of the terminal in the case that the terminal has the mobile trajectory information during the RRC non-connected state, the present application can obtain the predicted mobile trajectory information of the terminal in the case that the terminal is in the RRC non-connected state and has the predicted mobile trajectory information. The terminal initiates the first process, and indicates the mobile trajectory information to the network side device during the process of initiating the first process or after the first process ends, so as to quickly enter the RRC connected state and report the mobile trajectory information to the network side device. The network side device can obtain the mobile trajectory information of the terminal, so that the network side device can realize directional paging and optimize the transmission of the base station public signal in the case that the terminal is in the RRC non-connected state, and improve the network energy efficiency.

[0087] An embodiment of the present application provides an information reporting method, and FIG. 2 shows a flowchart of the information reporting method provided by the embodiment of the present application. As shown in FIG. 2, the information reporting method provided by the embodiment of the present application can include the following step 201.

[0088] In the case that a terminal is in an RRC non-connected state and has first mobile trajectory information, the terminal initiates a first process, and indicates the first mobile trajectory information to a network side device during the process of initiating the first process or after the first process ends.

[0089] It can be understood that the terminal in the RRC non-connected state and having the first mobile trajectory information can trigger the terminal to initiate the first procedure to indicate the first mobile trajectory information to the network side, or the terminal in the RRC non-connected state and having the first mobile trajectory information can trigger the terminal to indicate the first mobile trajectory information to the network side, or once it is received that the terminal in the RRC non-connected state has the first mobile trajectory information, the terminal initiates the first procedure to indicate the first mobile trajectory information to the network side device, or once it is received that the terminal in the RRC non-connected state has the first mobile trajectory information, the terminal indicates the first mobile trajectory information to the network side device.

[0090] In an implementation form, the terminal indicating the first mobile trajectory information to the network side includes: the terminal indicating to the network side that the terminal has the first mobile trajectory information, receiving a request for the first mobile trajectory information from the network side, and the terminal reporting the first mobile trajectory information to the network side.

[0091] In the embodiments of the present application, the RRC non-connected state includes an RRC idle state and an RRC inactive state.

[0092] In the embodiments of the present application, in the case that the terminal is in the RRC idle state, the first procedure is an RRC connection establishment procedure.

[0093] In the embodiments of the present application, in the case that the terminal is in the RRC inactive state, the first procedure is an RRC connection resumption procedure or an SDT procedure.

[0094] In the embodiments of the present application, the first mobile trajectory information represents a future mobile trajectory of the terminal predicted by the terminal.

[0095] Optionally, in the embodiments of the present application, the first mobile trajectory information can include cell residence information or location residence information.

[0096] For example, the cell residence information can include at least one of identification information of a cell, a residence timestamp in the cell, and a residence duration in the cell. For example, the identification information of the cell can be an NR cell global identifier (NCGI) or a physical cell identifier plus carrier (PCI+carrier).

[0097] For example, the residence timestamp can be an absolute timestamp, such as universal time coordinated (UTC).

[0098] For example, the location information can be GPS-based location information.

[0099] Exemplarily, the position staying information can include at least one of the position information, a staying timestamp at the position indicated by the position information, and a staying duration at the position indicated by the position information.

[0100] Optionally, in embodiments of the present application, the first moving track information can include at least one of the following:

[0101] The terminal predicts identity information of at least one cell in which the terminal stays;

[0102] The terminal predicts a staying timestamp in the at least one cell;

[0103] The terminal predicts a staying duration in the at least one cell.

[0104] Exemplarily, the identity information of at least one cell in which the terminal stays predicted by the terminal can be in the form of a cell list, and the cell list includes identity information of the at least one cell.

[0105] Optionally, in embodiments of the present application, the first moving track information can include at least one of the following:

[0106] The terminal predicts at least one position information;

[0107] The terminal predicts a staying timestamp corresponding to the at least one position information;

[0108] The terminal predicts a staying duration corresponding to the at least one position information.

[0109] In embodiments of the present application, after the network side device obtains the at least one position information predicted by the terminal, the network side device can deduce a cell in which the terminal stays according to the at least one position information.

[0110] It can be understood that the staying timestamp corresponding to the at least one position information predicted by the terminal refers to a staying timestamp at a position indicated by the at least one position information predicted by the terminal.

[0111] It can be understood that the staying duration corresponding to the at least one position information predicted by the terminal refers to a staying duration at a position indicated by the at least one position information predicted by the terminal.

[0112] In this way, after the terminal indicates the first moving track information to the network side device, in the case that the terminal returns to the RRC non-connected state, the network side device can also know the future moving track of the terminal, facilitating the network side device to perform directional paging and optimize transmission of a base station common signal.

[0113] Optionally, in embodiments of the present application, the terminal having the first moving track information can include any of the following:

[0114] The terminal has predicted any cell staying information or any position information;

[0115] The terminal has predicted moving track information meeting a specific condition, the specific condition being that the cells or locations included in the moving track information meet a condition.

[0116] It can be understood that the terminal having predicted any cell residence information or any location information means that the terminal has predicted cell residence information in any cell or location information in any location.

[0117] It can be understood that the terminal having predicted moving track information meeting a specific condition means that the terminal has predicted residence information or location information meeting a specific condition.

[0118] Optionally, in the embodiments of the present application, the specific condition includes at least one of the following:

[0119] The number of cells or locations included in the moving track information is greater than or equal to N, N being an integer greater than or equal to 1;

[0120] The residence duration of each cell or the residence duration of each location included in the moving track information is greater than or equal to a preset duration;

[0121] The historical repetition number of cells or locations included in the moving track information is greater than or equal to M, M being an integer greater than or equal to 1.

[0122] Optionally, in the embodiments of the present application, the historical repetition number of the cell means the number of times the terminal has previously resided in the cell, and the historical repetition number of the location means the number of times the terminal has previously resided in the location.

[0123] It can be understood that the residence duration of each cell or the residence duration of each location included in the moving track information is greater than or equal to a preset duration, and the moving track information is the track of the terminal in a relatively long period of time.

[0124] It can be understood that the historical repetition number of cells or locations included in the moving track information is greater than or equal to M, and the moving track information includes more cells or locations in which the terminal has previously resided, and the accuracy of the moving track information is higher.

[0125] It should be noted that if the terminal predicts moving track information in a short time dimension or the terminal predicts based on a small number of samples, etc., the reporting of the moving track information does not bring great benefits to the network and the terminal, but increases the energy consumption of the system. Therefore, the specific condition is to make some restrictions on the moving track information reported by the terminal, so as to reduce unnecessary triggering of the first process by the terminal and reporting of the moving track information of the terminal.

[0126] For example, the specific condition can include at least one of the following:

[0127] residence information of N cells or N location points in the mobile trajectory information;

[0128] the start time and the end time in the mobile trajectory information are not shorter than X;

[0129] the history repetition times of the cells or the location information included in the mobile trajectory information are not less than M;

[0130] It should be noted that the X is the preset time length.

[0131] Optionally, in the embodiments of the present application, the N and the M can be specified by a protocol, predefined or configured by a network. For example, N equals to 1, which means that the trajectory information of the terminal is available. For example, N is 5, X is 30 minutes, and M is 10.

[0132] In this way, the terminal indicates the first mobile trajectory information to the network side device in the case that the cells or the locations included in the predicted first mobile trajectory information are enough, or the predicted first mobile trajectory information is the trajectory in a long enough time period, or the accuracy of the predicted first mobile trajectory information is higher, so that the accuracy of the indicated first mobile trajectory information is higher, unnecessary trajectory information reporting is reduced, and the energy consumption of the system is reduced.

[0133] Optionally, in the embodiments of the present application, the terminal can record the history mobile information of the terminal based on internal implementation or in a standardized manner, and predict the mobile trajectory of the terminal in a future time period (i.e., the first mobile trajectory information is predicted) according to the current mobile behavior of the terminal (such as the residence cells or the areas in a current time period).

[0134] Optionally, in the embodiments of the present application, the "the terminal indicates the first mobile trajectory information to the network side device in the process of initiating the first procedure or after the first procedure ends" in the step 201 can be implemented through the following step 201a or step 201b.

[0135] The step 201a, in the case that the terminal has not reported the first mobile trajectory information before the terminal indicates the first mobile trajectory information to the network side device in the process of initiating the first procedure or after the first procedure ends, the terminal sends the first mobile trajectory information to the network side device.

[0136] The step 201b, in the case that the terminal has reported the first mobile trajectory information before the terminal indicates the first mobile trajectory information to the network side device in the process of initiating the first procedure or after the first procedure ends, and the first mobile trajectory information is in an invalid state, the terminal sends first indication information to the network side device.

[0137] In the embodiments of the present application, the first indication information indicates that the first mobile trajectory information resumes the valid state.

[0138] The first indication information includes an identifier of the first mobile trajectory information.

[0139] For example, the terminal reports the first mobile trajectory information at time T1, reports the second mobile trajectory information after changing the mobile trajectory information at time T2 (the network side can default that the first mobile trajectory information is invalid, but still saves the first mobile trajectory information), and predicts that the mobile trajectory information of the terminal is the first mobile trajectory information at time T3. Then, the terminal sends the first indication information to the network side device, and the first indication information includes an identifier of the first mobile trajectory information (the network side can default that the first mobile trajectory information is valid again). Further, the terminal can explicitly indicate that the first mobile trajectory information is in an invalid state or indicate that the first mobile trajectory information is mobile trajectory information that will be used multiple times by the terminal when reporting the second mobile trajectory information. In this way, the network side can decide to save the first mobile trajectory information and assign an identifier associated with the first mobile trajectory information to the terminal, and then send the identifier to the terminal. When the terminal predicts that the mobile trajectory information of the terminal is the first mobile trajectory information at time T3, the terminal sends the first indication information to the network side device, and the first indication information includes an identifier of the first mobile trajectory information. The identifier is the identifier assigned to the terminal by the network side. In other embodiments, the identifier of the mobile trajectory information can also be provided by the terminal when the terminal reports the mobile trajectory information.

[0140] For example, the terminal can report multiple sets of mobile trajectory information at a time. During the RRC non-connected state of the terminal, when a certain set of mobile trajectory information is determined, a first process is initiated, and the network side is indicated of the mobile trajectory information during the first process or after the first process ends. In this way, the signaling overhead of the terminal reporting the mobile trajectory information can be reduced, and the interaction efficiency can be improved. In this example, the terminal provides identifier information of multiple sets of mobile trajectory information when reporting the multiple sets of mobile trajectory information.

[0141] Optionally, after step 201, the information reporting method provided in the embodiment of the present application further includes at least one of the following:

[0142] In the case where the first mobile trajectory information is invalid, the terminal indicates to the network side device that the first mobile trajectory information is invalid.

[0143] In the case where the first mobile trajectory information of the terminal is changed, the terminal indicates to the network side device the updated first mobile trajectory information.

[0144] In this way, the network side avoids using inaccurate mobile trajectory information, which leads to the fact that the terminal in the RRC non-connected state cannot receive a paging message, or the network side cannot improve network energy consumption.

[0145] Optionally, in the embodiments of the present application, the terminal indicating the updated first moving track information to the network side device can include at least one of the following:

[0146] The terminal indicates the updated first moving track information to the network side device when the network side device allows.

[0147] The terminal indicates the updated first moving track information to the network side device when the variation of the first moving track information of the terminal meets a preset threshold.

[0148] Optionally, the network side device can send configuration information to the terminal, which is used to indicate that the terminal is allowed to report the updated first moving track information.

[0149] Optionally, in order to control the frequent initiation of the first process caused by the frequent change of the moving track of the terminal, the network side device can configure a preset threshold (which can also be a protocol agreement). When the expected deviation of the terminal exceeds the preset threshold, the terminal initiates the first process. The precondition is that the network can expand the range to page the terminal based on the information reported by the terminal. Alternatively, the network side device can flexibly enable / disable the terminal to report the moving track information.

[0150] It should be noted that the terminal initiating the first process is the terminal indicating the updated first moving track information to the network side device.

[0151] In this way, the frequent initiation of the first process caused by the frequent change of the moving track of the terminal can be reduced, and unnecessary operations can be reduced.

[0152] Optionally, in the embodiments of the present application, the terminal indicating the updated first moving track information to the network side device can be implemented by the following step 301.

[0153] In step 301, the terminal indicates the second moving track information to the network side device, and the second moving track information is different from the first moving track information.

[0154] Optionally, in the embodiments of the present application, when the cell information or the location information in the first moving track information and the second moving track information is the same, the second moving track information includes the residence time offset or the stay time offset.

[0155] Optionally, in the embodiments of the present application, when the cell information or the location information in the first moving track information and the second moving track information is the same, the second moving track information includes the residence time offset or the stay time offset.

[0156] It should be noted that the above path cell does not change means that the above cell information or location information is the same. The above time changes means that the residence time information is different or the stay time information is different.

[0157] Exemplarily, the residence time information includes a residence time stamp or a residence time length, and the stay time information includes a stay time stamp or a stay time length.

[0158] Optionally, in the embodiment of the application, the residence time offset includes a residence time offset of all cells or a reference cell in the second mobile trajectory information. The stay time offset includes a stay time offset of all locations or a reference location in the second mobile trajectory information.

[0159] Exemplarily, the terminal can indicate a time offset of each cell or each location; or the terminal can indicate a time offset of a reference cell or a reference location.

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

[0161] For example, the reference cell can be the last cell in the first mobile trajectory information or the second mobile trajectory information. The reference location can be the last location in the first or second mobile trajectory information.

[0162] For example, the reference cell can be a specified cell in the first mobile trajectory information or the second mobile trajectory information. The reference location can be a specified location in the first or second mobile trajectory information.

[0163] Exemplarily, the terminal can indicate the information of the reference cell to the network side when reporting the second mobile trajectory information, that is, indicate which cell or which cells the reference cell is.

[0164] In this way, the terminal only reports the residence time offset or the stay time offset in the second mobile trajectory information that is different from the first mobile trajectory information, which can reduce the signaling overhead of reporting and improve the information transmission efficiency.

[0165] Optionally, in the embodiment of the application, the step 201 of "the terminal indicates the first mobile trajectory information to the network side device in the process of initiating the first flow or after the first flow ends" can be implemented by the following step 201x.

[0166] Step 201x, in the case that the terminal is in an RRC non-connected state, has the first mobile trajectory information, and the network side device allows the terminal to report the first mobile trajectory information, the terminal indicates the first mobile trajectory information to the network side device in the process of initiating the first flow or after the first flow ends.

[0167] In the embodiments of the present application, the network side device can send configuration information to the terminal, and the configuration information indicates whether the terminal is allowed to initiate the first procedure in the RRC non-connected state and with the first mobile trajectory information.

[0168] In this way, whether the terminal can report the mobile trajectory information is controlled by the network side device, which can improve the flexibility of the network side in obtaining the mobile trajectory information of the terminal.

[0169] Optionally, in the embodiments of the present application, the terminal can indicate the first mobile trajectory information to the network side device through an RRC message or an NAS message during the process of initiating the first procedure or after the first procedure ends.

[0170] For example, the RRC message can be terminal assistance information, an RRC reconfiguration completion message, a terminal information response message, or an RRC connection recovery completion message.

[0171] For example, the NAS message can be a registration request message or a service request message.

[0172] Optionally, after the step 201, the information reporting method provided in the embodiments of the present application can further include the following step 401 or step 501.

[0173] In the case that the terminal indicates the first mobile trajectory information to the network side device through an NAS message, the terminal receives a response from the network side device in step 401.

[0174] In the embodiments of the present application, the response can include information of a registration area.

[0175] For example, in the case that the terminal is in an RRC idle state and has the first mobile trajectory information, the terminal sends an NAS message or triggers an NAS process, the NAS message can be a registration request message, and the NAS process can be a registration update process. After triggering the registration update process, the terminal can report the first mobile trajectory information in the registration update process, for example, by carrying the first mobile trajectory information in the registration request message. After receiving the registration request message, the network side device can reply a registration reception message to the terminal, and reconfigure a registration area (such as a TAI list) in the registration reception message.

[0176] It should be noted that the registration reception message is the response, and the registration area (such as the TAI list) is the information of the registration area.

[0177] Optionally, after the step 401, the information reporting method provided in the embodiments of the present application further includes the following step 402.

[0178] In step 402, in a case where the terminal is in the RRC idle state and the currently camped cell does not belong to the registration area, the terminal determines whether to perform the registration update according to whether the currently camped cell meets the cell or location where the terminal currently camps that is predicted in the first moving trajectory information.

[0179] Optionally, in the embodiments of the present application, in a case where the terminal is in the RRC idle state, the currently camped cell does not belong to the registration area, and the currently camped cell meets the cell or location where the terminal currently camps that is predicted in the first moving trajectory information, the terminal does not perform the registration update, or the terminal determines whether to perform the registration update in this case according to the configuration of the network side.

[0180] It can be understood that the currently camped cell meets the cell or location where the terminal currently camps that is predicted in the first moving trajectory information means that the currently camped cell is the same as the cell or location in the first moving trajectory information.

[0181] For example, after the terminal indicates the first moving trajectory information to the network side device, the terminal reenters the RRC idle state and performs cell selection and reselection. In a case where the cell reselected by the terminal does not belong to the registration area of the terminal but meets the moving trajectory information reported by the terminal (expected to be consistent), the terminal can not perform the moving registration update process. On this basis, the network side can page the terminal based on the first moving trajectory information of the terminal. Alternatively, in a case where the cell reselected by the terminal does not belong to the registration area of the terminal but meets the moving trajectory information reported by the terminal (expected to be consistent), the terminal can determine whether to perform the moving registration update process according to the configuration information of the network.

[0182] For example, the network side device can send configuration information to the terminal, and the configuration information is used to indicate whether the terminal is allowed to perform the moving registration update process.

[0183] It should be noted that the cell reselected by the terminal is the currently camped cell, the currently camped cell meets the moving trajectory information reported by the terminal means that the currently camped cell meets the cell or location where the terminal currently camps that is predicted in the first moving trajectory information, and the moving registration update process is the registration update.

[0184] In this way, in a case where the terminal leaves the registration area but the currently camped cell meets the first moving trajectory information, the terminal can not perform the registration update, and the network side device can still page the terminal.

[0185] Optionally, in the embodiments of the present application, in a case where the terminal is in the RRC idle state, the currently camped cell does not belong to the registration area, and the currently camped cell does not meet the cell or location where the terminal currently camps that is predicted in the first moving trajectory information, the terminal performs the registration update.

[0186] It can be understood that the current camped cell does not conform to the cell or the location where the terminal is predicted to camp in the first mobile trajectory information refers to that the current camped cell is different from the cell in the first mobile trajectory information and the location is different.

[0187] Exemplarily, when the cell to which the terminal reselects does not belong to the registration area of the terminal and does not conform to the mobile trajectory reported by the terminal (i.e., the expectation is inconsistent), the terminal needs to trigger the mobile registration update again.

[0188] It should be noted that the cell to which the terminal reselects is the current camped cell. The mobile trajectory that does not conform to the terminal is that the current camped cell does not conform to the cell or the location where the terminal is predicted to camp in the first mobile trajectory information. The mobile registration update process is the registration update.

[0189] Optionally, in the embodiment of the application, in the case that the terminal is in the RRC idle state, the current camped cell belongs to the registration area, and the current camped cell does not conform to the cell or the location where the terminal is predicted to camp in the first mobile trajectory information, the terminal performs the first operation.

[0190] Optionally, in the embodiment of the application, the first operation can include any of the following:

[0191] The terminal performs the registration update and updates the first mobile trajectory information;

[0192] The terminal does not perform the registration update;

[0193] The terminal determines whether to perform the registration update according to the network side configuration.

[0194] Exemplarily, when the cell to which the terminal reselects belongs to the registration area of the terminal but does not conform to the mobile trajectory reported by the terminal, the behavior of the terminal can include any of the following:

[0195] The terminal performs the mobile registration update and updates the mobile trajectory of the terminal;

[0196] The terminal does not perform the mobile registration update. The network side can page the terminal in the registration area after failing to attempt to page the terminal based on the mobile trajectory information reported by the terminal.

[0197] Whether the terminal performs the mobile registration update can be configured by the network side.

[0198] Step 501, in the case that the terminal indicates the first mobile trajectory information to the network side device through the RRC message, the terminal receives the response from the network side device.

[0199] In the embodiments of the present application, the response can include information of a RAN-based notification area (RNA).

[0200] For example, when the terminal is in the RRC inactive state and has the first mobile trajectory information, the terminal initiates an RRC connection recovery procedure, and the RRC message can be an RRC connection recovery request message. The terminal can report the first mobile trajectory information to the network side device during the RRC connection recovery procedure or after the RRC connection recovery. After receiving the first mobile trajectory information reported by the terminal, the network side device can reply to the terminal with a response including information of an RNA.

[0201] Optionally, after the step 501, the information reporting method provided in the embodiments of the present application further includes the following step 502.

[0202] In the step 502, when the terminal is in the RRC inactive state and the currently camped cell does not belong to the RAN-based notification area, the terminal determines whether to perform an RAN-based notification area update (RNAU) procedure according to whether the currently camped cell meets the terminal's currently camped cell or the predicted location in the first mobile trajectory information.

[0203] Optionally, in the embodiments of the present application, when the terminal is in the RRC inactive state, the currently camped cell does not belong to the RAN-based notification area, and the currently camped cell meets the terminal's currently camped cell or the predicted location in the first mobile trajectory information, the terminal does not perform the RAN-based notification area update, or the terminal determines whether to perform the RAN-based notification area update in this case according to the configuration of the network side.

[0204] For example, after the terminal indicates the first mobile trajectory information to the network side device, the terminal reenters the RRC idle state and performs cell selection and reselection. When the cell selected by the terminal does not belong to the RAN-based notification area of the terminal but meets the mobile trajectory information reported by the terminal (expected to be consistent), the terminal can not perform the RAN-based notification area update procedure. On this basis, the network side can page the terminal based on the first mobile trajectory information of the terminal. Alternatively, when the cell selected by the terminal does not belong to the RAN-based notification area of the terminal but meets the mobile trajectory information reported by the terminal (expected to be consistent), the terminal can determine whether to perform the RAN-based notification area update procedure according to the configuration information of the network.

[0205] For example, the network side device can send configuration information to the terminal, and the configuration information is used to indicate whether the terminal is allowed to perform the RAN-based notification area update procedure.

[0206] It should be noted that the cell to which the terminal reselects is the current camped cell. The movement trajectory information reported by the terminal is that the current camped cell is consistent with the cell or location predicted by the first movement trajectory information.

[0207] In this way, in the case that the terminal leaves the RAN notification area but the current camped cell is consistent with the first movement trajectory information, the terminal can not perform RAN notification area update, and the network side device can still page the terminal.

[0208] Optionally, in the embodiment of the present application, in the case that the terminal is in the RRC idle state, the current camped cell does not belong to the RAN notification area, and the current camped cell is not consistent with the cell or location predicted by the first movement trajectory information, the terminal performs RAN notification area update.

[0209] Exemplarily, when the cell to which the terminal reselects neither belongs to the RAN notification area of the terminal nor is consistent with the movement trajectory reported by the terminal (i.e., the expectation is inconsistent), the terminal needs to trigger RAN notification area update again.

[0210] It should be noted that the cell to which the terminal reselects is the current camped cell. The movement trajectory information reported by the terminal is that the current camped cell is consistent with the cell or location predicted by the first movement trajectory information.

[0211] Optionally, in the embodiment of the present application, in the case that the terminal is in the RRC idle state, the current camped cell belongs to the RAN notification area, and the current camped cell is not consistent with the cell or location predicted by the first movement trajectory information, the terminal performs a second operation.

[0212] Optionally, in the embodiment of the present application, the second operation can include any one of the following:

[0213] The terminal performs RAN notification area update and updates the first movement trajectory information;

[0214] The terminal does not perform RAN notification area update;

[0215] The terminal determines whether to perform RAN notification area update according to the configuration of the network side.

[0216] Exemplarily, when the cell to which the terminal reselects belongs to the RAN notification area of the terminal but is not consistent with the movement trajectory reported by the terminal, the behavior of the terminal can include any one of the following:

[0217] The terminal performs RAN notification area update and updates its own movement trajectory;

[0218] The terminal does not perform the RAN notification area update. The network side can page the terminal in the RAN notification area after failing to attempt to page the terminal based on the mobile trajectory information reported by the terminal.

[0219] Whether the terminal performs the RAN notification area update can be configured by the network side.

[0220] Optionally, in the embodiments of the present application, the "terminal initiates the first procedure" in the step 201 can be implemented through the following step 201c.

[0221] The step 201c, when the terminal is in the RRC inactive state and has the first mobile trajectory information, the terminal sends an RRC connection resume request message to the network side device.

[0222] In the embodiments of the present application, the RRC connection resume request message carries resume cause information, and the resume cause information can include at least one of the following:

[0223] RNAU;

[0224] The terminal needs to report the first mobile trajectory information.

[0225] Optionally, in the embodiments of the present application, when the terminal has the first mobile trajectory information during the RRC inactive state, the terminal triggers the RRC connection resume procedure, and can indicate the reason for this time of resume as RNAU or terminal reporting mobile trajectory information to the network side when requesting to resume the RRC connection.

[0226] For example, the terminal can indicate the reason for this time of resume through a specific resume cause value in the RRC connection resume request message, or through a specific logical channel identifier (Logical Channel IDentifier, LCID) field, and the like.

[0227] In this way, the terminal carries the resume cause information in the RRC connection resume request message to inform the network side device that this time of RRC connection resume request is related to the mobile trajectory information reporting, to determine whether to accept the connection resume request of the terminal, and in the case of acceptance, can request the mobile trajectory information from the terminal in the RRC connection resume message as soon as possible.

[0228] Optionally, in the embodiments of the present application, the "terminal indicates the first mobile trajectory information to the network side device in the process of initiating the first procedure or after the end of the first procedure" in the step 201 can be implemented through the following steps 201e and 201f.

[0229] The step 201e, the terminal receives an RRC connection resume message from the network side device.

[0230] In the embodiment of the present application, the second indication information is carried in the RRC connection recovery message, and the second indication information indicates or requests the terminal to report the movement trajectory information.

[0231] In step 201f, the terminal sends an RRC connection recovery completion message to the network side device.

[0232] In the embodiment of the present application, the first movement trajectory information is carried in the RRC connection recovery completion message.

[0233] Optionally, in the embodiment of the present application, the reporting of the first movement trajectory information can include the following ways:

[0234] Way 1: After the terminal sends the RRC connection recovery request message, the terminal receives the RRC connection recovery message, and the RRC connection recovery message indicates or requests the terminal to report the movement trajectory information. Then, the terminal carries the movement trajectory information in the RRC connection recovery completion message.

[0235] Way 2: After the terminal enters the RRC connected state through the RRC connection recovery, the network side requests the terminal to report the movement trajectory information of the terminal in the UE information response message through the UE information request message.

[0236] Way 3: After the terminal enters the RRC connected state through the RRC connection recovery, the terminal reports the movement trajectory information through the UE Assistance Information (UAI).

[0237] Optionally, in the embodiment of the present application, since the network side device can store the predicted movement trajectory information of the terminal during the RRC non-connected state of the terminal. Considering that the update and reporting of the movement trajectory information during this period can be an optional behavior, when the terminal is in the RRC connection establishment or recovery process or enters the RRC connected state, if the movement trajectory information of the terminal is still valid compared with the last reported movement trajectory information, the base station can directly obtain the last reported movement trajectory information from the core network device, and does not need to be predicted (the purpose of prediction is for the mobility management of the connected state).

[0238] Optionally, in the embodiment of the present application, after the RRC connection establishment or recovery process or entering the RRC connected state, the terminal can send third indication information to the network side device, and the third indication information is used to indicate the validity of the first movement trajectory information.

[0239] Optionally, in the embodiment of the present application, the terminal can carry the third indication information in the msg5 message.

[0240] Optionally, in embodiments of the present application, the network side device can also configure the validity verification condition to the terminal, and the terminal verifies the validity of the first mobile trajectory information according to the validity verification condition. For example, the network side device can configure and send the validity verification condition to the terminal through an RRC connection release message.

[0241] In this way, in the case that the network side device stores the mobile trajectory information predicted by the terminal during the RRC non-connected state, if the RRC connection is established or restored or the terminal is in the RRC connected state, the network side does not make a prediction, but directly uses the mobile trajectory information reported by the terminal before to perform paging in the case that the third indication information from the terminal indicates that the mobile trajectory information reported by the terminal before is valid, which can reduce the network energy consumption caused by prediction calculation.

[0242] The information reporting method provided by the embodiments of the present application can obtain the mobile trajectory information predicted by the terminal in time compared with the related art network side device which can only trigger the reporting of the mobile trajectory information in the case that the terminal has the mobile trajectory information and is in the RRC connected state, and cannot obtain the mobile trajectory information predicted by the terminal in the case that the terminal has the mobile trajectory information during the RRC non-connected state. In the case that the terminal is in the RRC non-connected state and has the predicted mobile trajectory information, the terminal initiates the first process, and indicates the mobile trajectory information it has to the network side device during the process of initiating the first process or after the first process is completed, so as to enter the RRC connected state as soon as possible to report the mobile trajectory information it has to the network side device, so that the network side device can know the mobile trajectory information of the terminal, and based on the mobile trajectory information, when the downlink service of the terminal arrives, the network side device can estimate the cell or position where the terminal is likely to camp at this moment, so as to notify the corresponding base station to direct the paging of the terminal, so as to reduce the paging overhead. In addition, the mobile trajectory information can be sent to the base station by the core network device, so as to estimate the approximate time when the terminal reselects to the cell, so as to start the sending of the system information, and reduce the power consumption and time delay caused by the sending of the wake-up signal by the terminal in multiple energy-saving cells.

[0243] FIG. 3 shows a flowchart of the information reporting method provided by the embodiments of the present application. As shown in FIG. 3, the information reporting method provided by the embodiments of the present application can include the following steps 601 to 604.

[0244] Step 601, the network side device sends configuration information to the terminal.

[0245] In an embodiment of the present application, the configuration information is used to indicate that the terminal indicates the first mobile trajectory information in the case that the terminal is in the RRC non-connected state and has the first mobile trajectory information. Optionally, in an embodiment of the present application, in order to avoid frequent registration update caused by frequent change of the mobile trajectory of the terminal, the network side device can send the configuration information to the terminal to indicate that the terminal is allowed to report the mobile trajectory information, and the terminal can report the mobile trajectory information to the network side device.

[0246] For example, the configuration information can be used to indicate whether the terminal is allowed to report the mobile trajectory information, or the configuration information can be used to indicate whether the terminal is allowed to report the updated mobile trajectory information, or the configuration information can be a preset threshold value used to indicate that the terminal reports the mobile trajectory information in the case that the preset threshold value is met.

[0247] In step 602, the terminal receives the configuration information from the network side device.

[0248] In step 603, the terminal sends a first message to the network side device.

[0249] In an embodiment of the present application, the first message is used to indicate the first mobile trajectory information possessed by the terminal. The first message is a message in the process of initiating the first procedure or a message after the first procedure is completed.

[0250] In an embodiment of the present application, in the case that the terminal is in the RRC idle state, the first procedure is an RRC connection establishment procedure. In the case that the terminal is in the RRC inactive state, the first procedure is an RRC connection recovery procedure or an SDT procedure.

[0251] For example, the first message can be a message in the RRC connection recovery procedure, such as the RRC connection recovery complete message. Alternatively, the first message can be a message in the RRC connection establishment procedure, such as the registration request message.

[0252] In step 604, the network side device receives the first message from the terminal.

[0253] Optionally, in an embodiment of the present application, the first mobile trajectory information includes at least one of the following:

[0254] identification information of at least one cell predicted to be camped by the terminal;

[0255] a camping time stamp of at least one cell predicted by the terminal;

[0256] a camping duration of at least one cell predicted by the terminal.

[0257] Optionally, in an embodiment of the present application, the first mobile trajectory information includes at least one of the following:

[0258] at least one location information predicted by the terminal;

[0259] a stay timestamp corresponding to the at least one location information predicted by the terminal;

[0260] a stay duration corresponding to the at least one location information predicted by the terminal.

[0261] Optionally, the step 602 can be implemented through the following step 602a or step 602b.

[0262] In the step 602a, the network-side device receives first movement track information from the terminal.

[0263] In the embodiment of the present application, the first movement track information has not been reported before.

[0264] In the step 602b, the network-side device receives first indication information from the terminal.

[0265] In the embodiment of the present application, the first indication information indicates that the first movement track information is in a valid state, and the first movement track information has been reported before and is in an invalid state.

[0266] Optionally, after the step 602, the information reporting method provided by the embodiment of the present application can further include at least one of the following steps 603 and 605.

[0267] In the step 603, the network-side device receives a second message from the terminal.

[0268] In the embodiment of the present application, the second message is used to indicate updated first movement track information, and the second message includes a stay time offset or a residence time offset.

[0269] For example, after receiving the configuration information from the network-side device, the terminal can know that the network-side device allows the terminal to report the movement track information, and thus, when determining that the first movement track information is updated, the terminal can send the second message to the network-side device.

[0270] In the step 605, the network-side device receives a third message from the terminal.

[0271] In the embodiment of the present application, the third message is used to indicate that the first movement track information is invalid.

[0272] Optionally, after the step 603, the information reporting method provided by the embodiment of the present application can further include the following step 61 or step 62.

[0273] In the step 61, the network-side device determines second movement track information according to the first movement track information and the stay time offset.

[0274] Optionally, in embodiments of the present application, the second mobile trajectory information is updated first mobile trajectory information.

[0275] For example, in the case where the residence time offset includes the residence time offset of each cell in the first mobile trajectory information, the network-side device can update the residence time stamp or the residence duration of each cell in the first mobile trajectory information according to the residence time offset, to obtain the second mobile trajectory information.

[0276] For example, in the case where the residence time offset includes the residence time offset of the first cell in the first mobile trajectory information, the network-side device can update the residence time stamp of the first cell according to the residence time offset of the first cell, and determine the updated residence time stamp of the second cell according to the updated residence duration of the first cell, and so on, to update the residence time stamp of each cell, and finally obtain the second mobile trajectory information.

[0277] Step 62, the network-side device determines the second mobile trajectory information according to the first mobile trajectory information and the residence time offset.

[0278] It should be noted that the implementation manner of the present step is the same as that of the above step 61, and thus will not be described herein again.

[0279] Optionally, in embodiments of the present application, the first message is a NAS message or an RRC message. After the above step 602, the information reporting method provided in embodiments of the present application can further include the following step 607 or step 608.

[0280] Step 607, in the case where the first message is a NAS message, the network-side device sends a response to the terminal in response to the NAS message.

[0281] In embodiments of the present application, the response includes information of a registration area.

[0282] Step 608, in the case where the first message is an RRC message, the network-side device sends a response to the terminal in response to the RRC message.

[0283] In embodiments of the present application, the response includes information of a RAN notification area.

[0284] Optionally, in embodiments of the present application, before the above step 602, the information reporting method provided in embodiments of the present application further includes the following step 602e, and correspondingly, the above step 602 can be implemented through the following step 602f.

[0285] Step 602e, the network-side device sends an RRC connection resume message to the terminal.

[0286] In the embodiment of the present application, the RRC connection resume message is used to indicate or request the terminal to report the movement trajectory information.

[0287] In step 602f, the network-side device receives the RRC connection resume complete message from the terminal.

[0288] In the embodiment of the present application, the first movement trajectory information is carried in the RRC connection resume complete message.

[0289] Optionally, before step 602e, the information reporting method provided in the embodiment of the present application further includes the following step 602d.

[0290] In step 602d, the network-side device receives the RRC connection resume request message from the terminal.

[0291] In the embodiment of the present application, the RRC connection resume request message carries the resume cause information, and the resume cause information includes at least one of the following:

[0292] RNAU;

[0293] The terminal needs to report the first movement trajectory information.

[0294] The information reporting method provided in the embodiment of the present application, in the case that the terminal is in the RRC non-connected state, the terminal enters the RRC connected state as soon as possible by initiating a first process, and timely reports the predicted movement trajectory information to the network-side device. The network-side device can obtain the movement trajectory information of the terminal by receiving the first message from the terminal, and based on the movement trajectory information, when the downlink service of the terminal arrives, the network-side device can estimate the cell or location where the terminal may camp at that time, so as to notify the corresponding base station to directionally page the terminal, so as to reduce the paging overhead. In addition, the first movement trajectory information can be sent to the base station by the core network device, so as to estimate the approximate time when the terminal reselects to the current cell, so as to start the transmission of system information, and reduce the power consumption and time delay caused by the terminal sending the wake-up signal in multiple energy-saving cells.

[0295] It should be noted that the specific implementation of the steps in the embodiment of the present application is the same as that of the related steps in the above-mentioned embodiment, and the parts not described in detail in the present embodiment can be referred to the related description of the above-mentioned embodiment, which will not be described herein again.

[0296] It should be noted that for the terminal with fixed movement trajectory time, the existing historical movement information recording behavior can also be directly improved. FIG. 4 shows a flowchart of the information reporting method provided in the embodiment of the present application. As shown in FIG. 4, the information reporting method provided in the embodiment of the present application can include the following steps 701 and 702.

[0297] Step 701. In a case where the terminal is in an RRC connected state, the terminal sends historical movement information of the terminal to a network side device.

[0298] In the embodiments of the present application, the historical movement information includes identification information of at least one historical cell and a residence time stamp of the terminal in the at least one historical cell.

[0299] For example, the historical cell can be a historical serving cell or a historical residence cell, and the residence time stamp can be an absolute time stamp, such as Universal Time Coordinated (UTC).

[0300] For example, the terminal can record the historical movement information of the terminal regardless of the RRC state of the terminal, and in a case where the terminal enters the RRC connected state, the terminal sends the historical movement information of the terminal to the network side device.

[0301] Optionally, in the embodiments of the present application, the historical movement information further includes at least one of the following:

[0302] a residence duration of the terminal in the at least one historical cell;

[0303] a residence frequency of the terminal in the at least one historical cell.

[0304] For example, the residence duration of the terminal in the at least one historical cell can include a residence duration of the terminal in at least one historical serving cell or historical residence cell, and the residence frequency of the terminal in the at least one historical cell can include a residence frequency of the terminal in at least one historical serving cell or historical residence cell.

[0305] Optionally, in the embodiments of the present application, the at least one historical cell includes at least one of the following:

[0306] a cell configured by the network side device when releasing the RRC connection;

[0307] a cell in which the terminal has historically resided and indicates the cell in which the terminal records the historical movement information;

[0308] a cell determined based on a specific rule, and the specific rule is related to a network energy saving state.

[0309] Optionally, in the embodiments of the present application, the specific rule includes any one of the following:

[0310] the residence cell is a network energy saving cell;

[0311] a cell in which the terminal sends a wake-up signal when the terminal resides in the cell.

[0312] Exemplarily, in order to reduce the impact on the terminal, the terminal can only record the timestamp information in a specific cell. The specific cell can be a cell configured by the network (dedicated signaling or the current cell camping instructs the terminal to record), or a cell determined based on a specific rule, for example, when the terminal camps in a network energy saving (NES) cell or a cell that sends a wake-up signal, the terminal can record the timestamp information in the cell.

[0313] It should be noted that the timestamp information is the camping timestamp described above. The cell in which the current cell camping instructs the terminal to record is a cell in which the terminal records historical movement information according to the indication of the cell in which the terminal historically camps.

[0314] In this way, the terminal reports the historical movement information to the network side device while in the RRC connected state. Since the historical movement information includes the camping timestamp of the terminal in at least one historical cell, the network side device can know the historical cells in which the terminal camps at different times, and thus, even if the terminal is released to the RRC non-connected state, the network side device can predict the movement trajectory of the terminal according to the historical movement information.

[0315] Step 702, the network side device receives the historical movement information from the terminal.

[0316] In the embodiments of the present application, the historical movement information can include identification information of at least one historical cell and a camping timestamp of the terminal in the at least one historical cell.

[0317] Optionally, in the embodiments of the present application, the network side device can be an access network device. Exemplarily, in combination with FIG. 4, as shown in FIG. 5, after step 702, the information reporting method provided by the embodiments of the present application can further include the following step 703.

[0318] Step 703, the access network device sends the historical movement information to the core network device.

[0319] Exemplarily, the base station sends the historical movement information reported by the terminal to a core network element, such as an AMF, an OAM, an NWDAF, etc. for storage.

[0320] Optionally, in the embodiments of the present application, the step 703 can be implemented by the following step 703a.

[0321] Step 703a, in the case where the core network device requests or subscribes to the historical movement information, the access network device sends the historical movement information to the core network device.

[0322] Exemplarily, the base station can send the historical movement information to the core network element in the case where the core network element requests or subscribes to the historical movement information.

[0323] Thus, the base station can estimate the probability that the terminal stays in some cells in some time periods during the RRC non-connected state according to the historical movement information reported by the terminal, thereby performing network optimization.

[0324] The information reporting method provided in the embodiments of the present application can be used to report the historical movement information of the terminal to the network side device when the terminal is in the RRC connected state. Since the historical movement information includes the stay time stamp of the terminal in at least one historical cell, the network side device can know the historical cells in which the terminal stays at different time points. Therefore, even if the terminal is released to the RRC non-connected state, the network side device can predict the movement trajectory of the terminal according to the historical movement information. When the downlink service of the terminal arrives, the network side device can estimate the cell or position in which the terminal is likely to stay at this time point, thereby notifying the corresponding base station to directionally page the terminal, so as to reduce the paging overhead.

[0325] It should be noted that the network side device can obtain the predicted movement trajectory information of the terminal before the RRC connection is released and use it after the RRC connection is released. FIG. 6 shows a flowchart of the information reporting method provided in the embodiments of the present application. As shown in FIG. 6, the information reporting method provided in the embodiments of the present application can include the following steps 801 and 802.

[0326] Step 801: When the terminal is in the RRC connected state and has third movement trajectory information, the terminal sends the third movement trajectory information to the network side device.

[0327] In the embodiments of the present application, the third movement trajectory information is used to determine the position of the terminal during the RRC non-connected state.

[0328] It can be understood that the network side device stores the third movement trajectory information sent by the terminal when the terminal is in the RRC connected state. In the case that the terminal is in the RRC non-connected state, the network side device can use the third movement trajectory information to predict the current position of the terminal, thereby realizing directional paging and optimizing the transmission of the base station common signal.

[0329] Further, the third movement trajectory can also be used to determine the position information of the terminal during the RRC connected state.

[0330] Optionally, in the embodiments of the present application, the third movement trajectory information can include at least one of the following:

[0331] The identification information of at least one cell in which the terminal is predicted to stay;

[0332] The stay time stamp of the at least one cell in which the terminal is predicted to stay;

[0333] The stay duration of the at least one cell in which the terminal is predicted to stay.

[0334] Optionally, in embodiments of the present application, the third movement trajectory information comprises at least one of the following:

[0335] at least one position information predicted by the terminal;

[0336] a stay timestamp corresponding to the at least one position information predicted by the terminal;

[0337] a stay duration corresponding to the at least one position information predicted by the terminal.

[0338] For example, when the terminal is in the RRC connected state, the terminal can report the predicted third movement trajectory information through an RRC message or a NAS message.

[0339] Optionally, in embodiments of the present application, the terminal can send the third movement trajectory information to the network side device upon receiving a request from the network side.

[0340] In embodiments of the present application, when the RRC connection of the terminal is released, the terminal does not delete the third movement trajectory information.

[0341] Step 802: The network side device receives the third movement trajectory information from the terminal.

[0342] In embodiments of the present application, the third movement trajectory information is used by the network side device to determine the position of the terminal during the RRC non-connected state.

[0343] Optionally, in embodiments of the present application, the network side device can be an access network device. In combination with FIG. 6, as shown in FIG. 7, after step 802, the information reporting method provided by embodiments of the present application can further comprise the following step 803.

[0344] Step 803: The access network device sends the third movement trajectory information to the core network device.

[0345] For example, when the terminal reports the predicted third movement trajectory information to the base station through an RRC message, the base station can send the third movement trajectory information reported by the terminal to a core network element such as an AMF, an OAM, an NWDAF, etc. for storage.

[0346] Optionally, in embodiments of the present application, step 803 can be implemented through the following step 803a.

[0347] Step 803a: When the core network device requests or subscribes to movement trajectory information, the access network device sends the third movement trajectory information to the core network device.

[0348] Exemplarily, the base station sends the third mobile trajectory information to the core network element in a case that the core network requests or subscribes the mobile trajectory information.

[0349] Optionally, in a case that the terminal is in the RRC non-connected state, the information reporting method provided in the embodiment of the application further includes the following step 901 or step 902.

[0350] Step 901, in a case that the terminal is in the RRC non-connected state, has the first mobile trajectory information, and the first mobile trajectory information is different from the third mobile trajectory information, the terminal initiates a first procedure, and indicates the first mobile trajectory information to the network side device in a process of initiating the first procedure or after the first procedure ends.

[0351] In a case that the terminal is in the RRC idle state, the first procedure is an RRC connection establishment procedure; in a case that the terminal is in the RRC inactive state, the first procedure is an RRC connection resumption procedure or an SDT procedure.

[0352] Step 902, in a case that the terminal is in the RRC non-connected state and the third mobile trajectory information is invalid, the terminal initiates a first procedure, and indicates that the third mobile trajectory information is invalid to the network side device in a process of initiating the first procedure or after the first procedure ends.

[0353] In a case that the terminal is in the RRC idle state, the first procedure is an RRC connection establishment procedure; in a case that the terminal is in the RRC inactive state, the first procedure is an RRC connection resumption procedure or an SDT procedure.

[0354] It should be noted that the implementation process of the terminal initiating the first procedure and indicating the first mobile trajectory information to the network side device in the process of initiating the first procedure or after the first procedure ends in the above steps 901 and 902 is the same as that in the above embodiment, and the parts not specifically described in the steps 901 and 902 can be referred to the related description of the above embodiment, which will not be described herein again.

[0355] Optionally, after the above step 802, the information reporting method provided in the embodiment of the application further includes the following step 805.

[0356] Step 805, the network side device receives a fourth message from the terminal.

[0357] In the embodiment of the application, the fourth message is used to indicate the first mobile trajectory information possessed by the terminal, or the fourth message is used to indicate that the third mobile trajectory information is invalid.

[0358] In the embodiments of this application, the fourth message is a message in the RRC connection establishment process, or the fourth message is a message in the RRC connection recovery process or the SDT process. For example, the fourth message is a registration request message in the RRC connection establishment process, or the fourth message is an RRC connection recovery complete message in the RRC connection recovery process.

[0359] The information reporting method provided in the embodiments of this application, in the case that the terminal is in the RRC connected state and has the third mobile trajectory information, the terminal sends the third mobile trajectory information to the network side device, and the network side device can determine the position of the terminal during the RRC non-connected state according to the third mobile trajectory information. After the terminal is released to the RRC non-connected state by the network side, the first process is not initiated immediately, but it is determined whether the third mobile trajectory information reported in the RRC connected state is the same as the first mobile trajectory information currently possessed by the terminal. If yes, the third mobile trajectory information is continued to be used, and the base station can estimate the approximate time when the terminal reselects to the current cell, so as to start the transmission of the system information, thereby reducing the power consumption and time delay caused by the terminal sending the wake-up signal in multiple energy-saving cells. If no, the terminal initiates the first process to re-report the first mobile trajectory information, and when the downlink service of the terminal arrives, the network side device can estimate the cell or position where the terminal is likely to camp at that moment, even if the terminal is in the RRC non-connected state, so as to notify the corresponding base station to directionally page the terminal, thereby achieving the purpose of reducing the paging overhead.

[0360] It should be noted that the specific implementation of part of the steps in the embodiments of this application is the same as that of the related steps in the above embodiments, and the parts not described in detail in this embodiment can refer to the related description of the above embodiments, which will not be described herein again.

[0361] It should be noted that each method embodiment or each possible implementation manner in the method embodiments can be executed alone or in combination with any two or more, and the specific execution can be determined according to actual use requirements, and the embodiments of this application do not limit this.

[0362] The information reporting method provided in the embodiments of this application, the execution subject can be an information reporting device. In the embodiments of this application, the information reporting method is executed by the information reporting device, and the information reporting device provided in the embodiments of this application is described.

[0363] Embodiments of the present application provide an information reporting apparatus. As an example, the information reporting apparatus can be a communication device or a component in a communication device, such as a chip. The communication device can be a terminal, a network-side device, a server, or the like. For example, the terminal can include, but is not limited to, the types of terminals 11 listed above, the network-side device can include, but is not limited to, the types of network-side devices 12 listed above, and embodiments of the present application do not make specific limitations.

[0364] The information reporting apparatus includes a receiving module, a sending module, and a processing module. The receiving module, the sending module, and the processing module can be implemented by software or by hardware. When implemented by hardware, the processing module can be implemented by a processor. For example, the processor can include a general-purpose processor, a special-purpose processor, or the like, such as a central processing unit (CPU), a microprocessor, a digital signal processor (DSP), an artificial intelligent (AI) processor, a graphics processing unit (GPU), an application specific integrated circuit (ASIC), a network processor (NP), a field programmable gate array (FPGA), or other programmable logic devices, a gate circuit, a transistor, a discrete hardware component, or the like.
