[0002] With the development of communication technology, wireless network coverage continues to increase, becoming an indispensable part of modern communication systems. Wireless networks are composed of multiple base stations (BS) and user equipment (UE). Base stations communicate with terminals through radio signals to provide voice, data, and multimedia services. Base stations are usually distributed in a certain geographical area. Each base station is responsible for covering the cell where it is located, and terminal devices move freely within these cells. The communication quality between base stations and terminals is crucial to the performance of the entire network and user experience.

[0028] With the continuous development of wireless communication technology, communication networks have become an important part of modern communication systems. In a communication network, such as a cellular network, a geographical area is divided into multiple cells, each of which is covered by a base station. The core feature of a cellular network is that through frequency reuse technology, multiple base stations can operate at the same frequency without interfering with each other, thereby improving the capacity and coverage of the network. The communication network involved in this application includes the first generation mobile communication technology 1G (first generation), the second generation mobile communication technology 2G (second generation), the third generation mobile communication technology 3G (third generation), the fourth generation mobile communication technology 4G (fourth generation), the fifth generation mobile communication technology 5G (fifth generation) and the sixth generation mobile communication technology 6G (sixth generation) or more generations of mobile communication technology in the future, which are not specifically limited here. The communication quality between the base station and the terminal is crucial to the performance and user experience of the entire network. In order to maintain the communication quality, when the terminal moves or encounters interference, it is usually necessary to switch between different cells or different base stations. Cell switching means that when the signal quality of the cell to which the terminal is currently connected drops below a certain threshold, or when certain switching conditions are met, the terminal needs to switch to a target cell with a stronger signal to maintain the continuity and stability of communication.

[0029] The following is a description with reference to the accompanying drawings.

[0030] Please refer to Figure 1, which shows a schematic diagram of a communication system provided in some embodiments of the present application. In the network structure, it includes: a control unit 110, and at least one base station communicating with it, for example, the control unit 110 only communicates with the base station 121, or the control unit 110 communicates with the base station 121, the base station 122, ..., the base station 12N at the same time. The control unit 110 and the base station constitute the network side 10 of the network structure. The coverage range of the base station can form one or more sectors, and the sector uses one or more wireless carriers to complete the wireless coverage. Each wireless carrier uses a certain carrier frequency point. The sector and the carrier form a cell, which provides the minimum service unit for the terminal to access. For example, the base station 121 forms at least one sector 130, and the sector includes at least one cell 131. The cell 131 provides wireless communication services for the terminal 140. When the signal quality of the cell where the terminal 140 is located drops below a certain threshold, or when a certain switching condition is met, the terminal 140 needs to switch to a target cell with a stronger signal, and the measurement report will be reported to the control unit through the base station 121. The control unit 110 determines whether it is necessary to switch the terminal 140 to other cells or base stations according to the content of the measurement report reported by the terminal 140, that is, selects a suitable cell as the target cell for the terminal 140, and controls the terminal to switch to the target cell. However, there are still some challenges in the actual application of terminal switching cells. For example, with the increase of network density and the reduction of cell coverage, the terminal may switch from a cell with a better signal to a cell with a weaker signal due to problems such as base station failure, communication disorder, and delay in reporting measurement reports by the terminal, or frequently switch cells under the instruction of the base station, which may cause switching failure, increased switching delay, signal degradation, etc., resulting in a decrease in user experience. The information processing method, device, terminal, and communication system provided in the present application optimize the cell measurement information processing process by the terminal, adjust the measurement report reporting logic, ensure that the terminal resides in a cell with a stronger signal, and improve the stability of network services.

[0031] Please refer to Figure 2 , which shows an example flow chart of an information processing method provided in some embodiments of the present application. The method is used by a terminal to determine to send a measurement report, and at least includes the following steps:

[0032] S210: Acquire first signaling sent by a base station, where the first signaling includes measurement configuration information;

[0033] S220: Determine a signal parameter of a cell based on the first signaling, wherein the signal parameter is determined based on the measurement configuration information, and the cell includes: one or more of a first cell and a second cell, the first cell is a cell in which the terminal is currently stationed, and the first cell is adjacent to the second cell;

[0034] S230: Determine to send a measurement report based on the determination result and a preset condition, where the preset condition is determined based on the measurement configuration information, including: a periodic condition or an event condition;

[0035] S241: When the first signal parameter meets the first threshold, determine not to send the measurement report, and the first signal parameter is determined based on the first cell;

[0036] S242: When the first signal parameter does not meet the first threshold and the second cell meets a preset condition, determine to send a measurement report.

[0037] When the terminal 140 performs cell switching, the control unit 120 is based on the measurement report reported by the terminal 140. The cell may include: one or more of a serving cell, a co-frequency neighboring cell, a heterogeneous frequency neighboring cell, and a heterogeneous standard neighboring cell. For example, the measurement report may include: received signal strength indicator (RSSI), reference signal received power (RSRP), reference signal received quality (RSRQ), signal-to-noise ratio (SNR) and other information. The control unit 120 decides whether to perform a switching operation based on the measurement report and the preset switching conditions. Before performing a cell switching, the base station 121 may send a dedicated signaling (which may be referred to as a first signaling) to the terminal 140 through an air interface message, such as RRC signaling, such as RRC Reconfiguration, RRC Resume, etc. The dedicated signaling may carry measurement configuration information (RRCMeasConfig), and the measurement configuration information includes measurement object (MeasObject) information and report configuration information. The terminal 140 will perform connected state measurement based on the measurement object information in the measurement configuration information. The measurement object information is in units of frequency points. Each measured object frequency point is independent. The measurement object may include measurement bandwidth (allowed meas band width), neighboring blacklist (black cells), neighboring whitelist (white cells), etc. After measuring the cell, the terminal 140 will determine the signal parameters of the cell based on the report configuration information in the measurement configuration information. For example, the signal parameters may include information such as received signal strength indication, reference signal received power, reference signal received quality, signal-to-noise ratio, etc., and evaluate the determination result and preset conditions to determine whether to send a measurement report. The preset conditions are determined based on the report configuration, and are divided into periodic trigger reports (periodical report) and event trigger reports (event report) according to the trigger type. In the case of periodic trigger reporting, the purpose of periodic triggering will be configured in the report configuration, such as reporting the CGI information of a specified cell, reporting the optimal cell for a certain frequency; in the case of event trigger reporting, a certain event will be configured in the report configuration, such as any one of the A1, A2, A3, A4, A5, A6, B1, and B2 events, as well as the necessary duration to meet the triggering conditions. In addition, the report configuration can also include the maximum number of measurement reports, the interval time of measurement reports, and the signal parameters used in event trigger reporting. Among them, event A1 indicates that the signal value of the serving cell is higher than the threshold. Event A2 indicates that the signal value of the serving cell is lower than the threshold.Event A3 indicates that the neighboring cell signal value is better than the serving cell signal value. Event A4 indicates that the neighboring cell signal value is higher than the threshold. Event A5 indicates that the serving cell signal value is lower than threshold 1, and the neighboring cell signal value is higher than threshold 2. Event A6 indicates that the neighboring cell signal value is better than the auxiliary serving cell signal value to a certain extent. Event B1 indicates that the heterogeneous neighboring cell signal value is higher than the threshold. Event B2 indicates that the serving cell signal value is lower than threshold 1, and the heterogeneous neighboring cell signal value is higher than threshold 2. When switching between different cells, it can be achieved through the same frequency technology (Same Frequency, Intra-Frequency), heterogeneous frequency technology (Different Frequency, Inter-Frequency), or heterogeneous technology (Different Radio Access Technologies, Inter-RAT). The same frequency technology refers to that in a wireless communication network, two cells use the same frequency for communication. For example, when a terminal switches between two adjacent cells, if the two cells use the same frequency band and frequency resources, the switching between the two is the same frequency switching. The heterogeneous frequency technology refers to that the two cells use different frequencies for communication. For example, when a terminal switches from one cell to another neighboring cell using a different frequency band, this switching is called heterogeneous frequency switching. Heterogeneous technology refers to switching between different radio access technologies (RATs). For example, when a terminal switches from a 4G network based on LTE to a 5G network based on NR, or from LTE to a 3G network based on UMTS, this switching is called heterogeneous frequency switching.

[0038] When the terminal measures a certain result, even if the second cell adjacent to the first cell has met the preset conditions for connection state measurement reporting, but the first signal parameter of the first cell meets the first threshold, such as greater than the first threshold or equal to the first threshold, it can be considered that the signal of the first cell currently serving is good enough, and the terminal does not send this measurement report. The base station and the control unit cannot receive the measurement report, and may not adjust the first cell where the terminal resides to ensure the stability of the network service and improve the network quality. However, when the first signal parameter does not meet the first threshold, and the second cell meets the preset conditions for reporting, it means that the signal of the second cell may be better than the first cell at this time, and the terminal sends a measurement report to the control unit through the base station, in the hope of switching cells and improving the current network quality.

[0039] In some embodiments of the present application, the first signal parameter may include a first signal-to-noise ratio, and the first threshold may include a first signal-to-noise ratio threshold; when the first signal-to-noise ratio is greater than or equal to the first signal-to-noise ratio threshold, it is determined not to send the measurement report. The signal-to-noise ratio is an important parameter for measuring signal quality, which indicates the ratio of the power of a useful signal to the noise power, and is usually expressed in decibels (dB). The higher the first signal-to-noise ratio, the stronger the signal of the current first cell, the weaker the noise, the easier it is to receive and decode the transmitted data, the lower the bit error rate, and the more stable the communication link is, and it is not easily affected by external interference. Therefore, when the first signal-to-noise ratio is greater than or equal to the first signal-to-noise ratio threshold, the terminal 140 may not perform cell switching to ensure the stability of network services.

[0040] In some embodiments of the present application, the reference signal received power and the signal-to-noise ratio parameters can be used to jointly determine whether the terminal sends a measurement report. The reference signal received power can be used to evaluate the network signal strength, indicating the strength of the signal received by the terminal. For example, when the terminal is close to the base station or the base station has a strong transmit power, the reference signal received power measured by the terminal is large. A higher reference signal received power is accompanied by a lower bit error rate and a higher data transmission rate, and the receiving end (terminal or base station) is more likely to correctly decode the signal. In this case, the terminal can more reliably receive the signal of the base station, thereby improving the communication quality. Therefore, the first signal parameter may include: a first reference signal received power and a first signal-to-noise ratio, and the first threshold also includes a first reference signal received power threshold and a second signal-to-noise ratio threshold. When the first reference signal received power is greater than or equal to the first reference signal received power threshold, and the first signal-to-noise ratio is greater than or equal to the second signal-to-noise ratio threshold, it is determined not to send the measurement report, wherein the second signal-to-noise ratio threshold is less than the first signal-to-noise ratio threshold. When the second signal-to-noise ratio cannot meet the first signal-to-noise ratio threshold, but meets the second signal-to-noise ratio threshold, it means that the network service provided by the first cell is worse than that of the first cell that can provide the first signal-to-noise ratio, but at this time the first cell can still support the network demand of the terminal. Therefore, a parameter comparison of the first reference signal received power can be introduced, and when the first reference signal received power is greater than or equal to the first reference signal received power threshold, the terminal determines not to send a measurement report and continues to reside in the first cell.

[0041] In some implementations of the present application, the terminal can also determine whether to send a measurement report in combination with the determination results of measuring the first cell and the second cell. When the first signal parameter and the second signal parameter meet the second threshold, it is determined not to send the measurement report, and the second signal parameter is determined based on measuring the second cell. By comparing the first signal parameter with the second signal parameter, for example, when the first signal parameter is greater than or equal to the second signal parameter, even if the second cell meets the preset condition, the terminal still does not send the measurement report, and when the first signal parameter is less than the second signal parameter, the terminal sends the measurement report in the expectation that the control unit performs cell switching in time to ensure the quality of network service. Alternatively, when the first signal parameter is less than the second signal parameter and the second cell meets the preset condition, the terminal sends the measurement report to ensure that the network service provided by the second cell to be switched is better than the currently resident first cell, thereby improving the accuracy of cell switching. In some implementations of the present application, the second signal parameter may include a second signal-to-noise ratio; when the difference between the first signal-to-noise ratio and the second signal-to-noise ratio is greater than or equal to the second threshold, and when the second cell meets the preset condition, it is determined not to send the measurement report. By comparing the signal-to-noise ratios of the first cell and the second cell, the signal strengths provided by the first cell and the second cell are determined, so that the terminal determines whether to send a measurement report to the control unit, thereby further improving the accuracy of the terminal camping on or switching cells.

[0042] In some embodiments of the present application, the first signaling further includes: a self-switching instruction. Step S220 determines the signal parameters of the cell based on the first signaling, and may include: when the number of times the self-switching instruction is obtained within the first preset time is greater than or equal to a third threshold, recording the cell information of the first cell, and reducing the first signal parameter of the first cell, the cell information including: frequency information, identification information or system time.

[0043] When the terminal receives the self-switching instruction, it will switch in the same cell, such as switching from the first cell to the first cell. The starting condition of the self-switching instruction may include: the network may adjust the network resource configuration of the current resident cell to allow the terminal to use the new configuration. Or, the network itself is abnormal, such as the network hopes to control the transmission of terminal data by constantly adjusting a certain configuration, but due to network design defects, the control process is sent in the form of self-switching, so that the base station sends a self-switching instruction to the terminal. When the terminal continues to receive the self-switching instruction within a certain period of time, the terminal will continue to self-switching, thereby affecting the stability of the network and generating risks such as delays. Therefore, in some embodiments of the present application, by judging the number of self-switching instructions obtained by the terminal within the first preset time, when the third threshold is met, it indicates that the cell or base station where the terminal currently resides may be abnormal, and the terminal expects the control unit to switch the cell where it resides at this time. Therefore, the first signal parameter of the first cell can be reduced to achieve the purpose of prompting the terminal to report the measurement report in the subsequent measurement process and increase the probability of the control unit performing cell switching. For example, starting from the time when the number of self-switching instructions meets the third threshold, the terminal records the cell information of the first cell, and gradually reduces the first signal parameter when the terminal receives the self-switching instruction next time. The reduction of the first signal parameter can be determined based on the following formula 1:

[0044]

[0045] Among them, M p is the adjusted first signal parameter, M n is the current first signal parameter, Q is the offset factor, and offset is the custom offset value. The offset factor Q can be determined based on the number of times the self-switching instruction is received again after the number of self-switching instructions meets the third threshold. For example, if the third threshold is x, then when the terminal receives the x+1th self-switching instruction, the offset factor Q can be set to 1, and when the terminal receives the x+2th self-switching instruction, the offset factor Q can be adjusted to 2, and so on. The custom offset value offset can be determined based on the minimum value specified in the relevant communication protocol, so that it is combined with the offset factor Q and the current first signal parameter M. n In the case of pNot less than the minimum value specified in the relevant communication protocol. Or specifically designed in combination with the signal requirements of the terminal, base station and control unit. The first signal parameter may include parameters such as reference signal received power and signal-to-noise ratio. For example, by reducing the reference signal received power, the first reference signal received power does not meet the first reference signal received power threshold, and the terminal determines to send a measurement report. For another example, by reducing the signal-to-noise ratio, the first signal-to-noise ratio does not meet the first signal-to-noise ratio threshold. For another example, by reducing the signal-to-noise ratio, the difference between the first signal-to-noise ratio and the second signal-to-noise ratio does not meet the second threshold.

[0046] In some embodiments of the present application, when the difference between the first system time and the second system time is greater than or equal to the second preset time, the cell information of the first cell is deleted; wherein the first system time is determined based on the currently recorded cell information, and the second system time is determined based on the previously recorded cell information. When the difference between the first system time and the second system time is greater than or equal to the second preset time, it indicates that the self-switching instruction received by the terminal this time has been separated by a longer time compared to the last time the self-switching instruction was received, and there may be more reasonable reasons for the previous self-switching instruction and the current self-switching instruction, and base station failure, control unit control disorder and other reasons can be excluded. Whenever the terminal receives a switching instruction (regardless of whether it is a self-switching instruction), it will refresh and check the maintained self-switching cell list. When it is found that the recording time of a certain cell is greater than the second preset time, the cell record will be deleted from the maintenance list.

[0047] Please refer to Figure 3 , which shows an example flow chart of another information processing method provided in some embodiments of the present application. It includes at least the following steps:

[0048] S310: The terminal receives measurement configuration information sent by the control unit through the base station, and performs measurement on the measurement object;

[0049] S320: After measuring the cell, the terminal performs measurement evaluation on the cell measurement result according to the report configuration;

[0050] S331: The first reference signal power RSRP1 of the serving cell is greater than the threshold Th1, and the first signal-to-noise ratio SNR1 of the serving cell is greater than the threshold Th2;

[0051] S332: The first signal-to-noise ratio SNR1 of the serving cell is greater than a threshold Th3;

[0052] S333: The first signal-to-noise ratio SNR1 of the serving cell minus the second signal-to-noise ratio SNR2 of the neighboring cell is greater than a threshold Th4;

[0053] S341: prevent sending measurement report;

[0054] S342: Allow sending of measurement report.

[0055] In the above steps, the serving cell is the cell where the terminal currently resides, and the neighboring cell is the cell adjacent to the cell where the terminal currently resides. In the process of measurement evaluation, step S320 evaluates whether the cell measurement result satisfies any one of the conditions in step S331, S332 or S333. If any of the conditions are met, step S341 is executed, the terminal does not send a measurement report, and the network side does not control the cell switching; if any of the conditions are not met, step S342 is executed, and the terminal sends a measurement report to prompt the network side to control the cell switching.

[0056] Please refer to Figure 4 , which shows an example flow chart of another information processing method provided in some embodiments of the present application. It at least includes the following steps:

[0057] S410: The terminal receives a switching instruction sent by the network side in a connected state;

[0058] S420: Whether the switching instruction is a self-switching instruction;

[0059] S421: The terminal switches to a target cell;

[0060] S430: The terminal performs handover and records the number of times the terminal has performed self-handover in the current serving cell. Each time a self-handover is performed, the number of self-handovers of the cell is increased by 1.

[0061] S440: The number of self-switching of the terminal in the current serving cell reaches a specific number N;

[0062] S450: Add / update the serving cell frequency, physical cell ID, and terminal system time at the time of self-switching to the self-switching cell list;

[0063] S460: In subsequent measurement and evaluation, lowering the serving cell reference signal received power value used;

[0064] S470: In subsequent measurement and evaluation, the adjusted serving cell reference signal received power value is used for reporting to increase the chance of reporting conditions for neighboring cell triggering events.

[0065] In the above steps, when the terminal receives the switching instruction, it determines whether the switching instruction is a self-switching instruction. If it is a self-switching instruction, step S430 is executed. If it is not a self-switching instruction, the terminal switches to the target cell, and the target cell is determined based on the cell indicated in the switching instruction. In step S440, when the number of self-switching reaches a specific number N, if the currently received signaling contains measurement configuration information, it can be chosen not to adjust the reference signal received power value of the serving cell at present, and to adjust it when the self-switching instruction is received next time. Alternatively, it is chosen to directly adjust the reference signal received power value of the current serving cell. When sending a measurement report, the adjusted reference signal received power value of the serving cell is reported.

[0066] A processor is a circuit with the ability to process signals. For example, a processor includes a circuit with the ability to read and run instructions, such as a CPU, a microprocessor, a graphics processing unit (GPU) or a digital signal processor (DSP).
