Abstract

The invention discloses a reselection priority compensation method and device based on a terminal signal quality measurement result. The method comprises the following steps: judging whether a frequency band where a current service cell is located has the highest reselection priority or not; monitoring the signal quality of the serving cell and the pilot frequency neighbor cell; when the triggering condition is met, a reselection priority compensation mechanism is started; using an A5 measurement report counter and a timer to control the compensation process; and dynamically adjusting the reselection priority of the frequency band where the service cell is located. Through the dynamic adjustment mechanism, the problem caused by the fixed frequency band reselection priority is effectively solved. When the signal quality of the high-priority frequency band is obviously lower than that of the low-priority frequency band, the terminal can temporarily reduce the reselection priority of the high-priority frequency band, thereby avoiding frequent switching and reselection operations. Therefore, not only is unnecessary signaling load reduced, but also the power consumption of the terminal is reduced, and the stability of data transmission is improved.

Description

Technical Field

[0001] The present invention relates to the field of terminal technology, and in particular to a method, device, intelligent terminal and storage medium for compensating for reselection priority based on terminal signal quality measurement results. Background Art

[0002] In the prior art, after a terminal establishes an RRC connection with a serving cell base station, the serving cell base station will configure a measurement task for the terminal connected to this cell. The measurement task includes three elements: measurement object, test event, and measurement report. When the signal quality of the serving cell and the neighboring cell defined in the measurement object measured by the terminal meets the measurement event conditions, the terminal sends a measurement report to the base station. The base station determines whether to send a switching instruction to require the terminal device to switch to a neighboring cell that meets the switching conditions based on the received measurement report. When the terminal completes a data transmission service with the serving cell base station and there is no new uplink and downlink data transmission, the serving cell base station sends an instruction to release the RRC connection between the terminal. The terminal will select the optimal neighboring cell based on the neighboring cell relationship configured in the SIB4 message or RRC connection release message sent by the currently resident cell and wait for the next data transmission.

[0003] A disadvantage of the existing technology is that when the serving cell is configured with an A5 measurement task (i.e., the serving cell signal quality falls below a set threshold, while the neighboring cell signal quality defined in the measurement object exceeds the set threshold), and the base station configures the neighboring cell's frequency band to have a lower reselection priority than the current serving cell, if the neighboring cell's signal quality is higher than the serving cell's. For example, if the serving cell's signal quality is -110 dBm and the neighboring cell's signal quality is -90 dBm, the terminal may be instructed by the base station to switch to the neighboring cell during data transmission with the serving cell because the neighboring cell's signal quality meets the handover criteria. After data transmission is completed and the RRC connection is released, the terminal will return to the previous serving cell based on the cell reselection priority, because the reselection priority of the new serving cell's frequency band is lower than that of the previous serving cell, and reselection to the higher-priority frequency band only requires the terminal's measured signal quality of the higher-priority frequency band to be higher than the threshold set in SIB4, regardless of the signal quality of the current serving cell. This repeated cell handover during data transmission and return to the higher-priority cell after the data transmission is completed creates additional signaling overhead, increasing terminal power consumption and causing unstable data transmission.

[0004] Therefore, the existing technology still needs to be improved and developed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that, in response to the problems and defects of the above-mentioned prior art, a reselection priority compensation method, device, intelligent terminal and storage medium based on the terminal signal quality measurement results are provided, aiming to solve the problem of frequent terminal switching and reselection caused by fixed frequency band reselection priority in the prior art. The present invention dynamically adjusts the frequency band reselection priority by setting the frequency band reselection priority compensation by the terminal, thereby avoiding the problem that the fixed frequency band reselection priority set by the network cannot solve the problem of cyclic switching and cell reselection between frequency bands caused by the signal quality of the high priority frequency band being significantly lower than the signal quality of the low priority frequency band.

[0006] The technical solutions adopted by the present invention to solve the problem are as follows:

[0007] A method for compensating reselection priority based on terminal signal quality measurement results, comprising:

[0008] A. When the terminal establishes a connection with the current serving cell base station, the current serving cell base station configures a measurement task for the terminal connected to the cell;

[0009] B. The terminal determines whether the frequency band of the current serving cell has the highest reselection priority;

[0010] C. When the terminal determines that the current serving cell frequency band has the highest reselection priority and the serving cell signal quality meets a preset trigger condition, the terminal is controlled to initiate a reselection priority compensation mechanism; wherein the preset trigger condition is that the current serving cell signal quality is lower than the first threshold set for the A5 event, and the inter-frequency neighbor cell signal quality is higher than the second threshold of the A5 event, and an A5 event measurement report is triggered;

[0011] D. When the terminal starts the reselection priority compensation mechanism, the control terminal starts the A5 measurement report counter and adds 1, starts the A5 measurement report timer at the same time, and reduces the reselection priority of the frequency band of the current serving cell by 1:

[0012] E. When the terminal detects that the signal quality of the serving cell meets the preset trigger condition again before the expiration of the A5 measurement report timer, the A5 measurement report timer is controlled to increase by 1, and the frequency band reselection priority of the current serving cell is reduced by 1; and after the data transmission service is completed, the terminal evaluates the candidate cells for reselection according to the new frequency band priority and completes the cell reselection;

[0013] F. When the A5 measurement report timer times out, the A5 measurement report timer and the serving cell frequency band reselection priority compensation are cleared.

[0014] This invention effectively solves the problem caused by fixed frequency band reselection priorities through this dynamic adjustment mechanism. When the signal quality of a high-priority frequency band is significantly lower than that of a low-priority frequency band, the terminal can temporarily lower the reselection priority of the high-priority frequency band, thereby avoiding frequent switching and reselection operations. This not only reduces unnecessary signaling load, but also lowers terminal power consumption and improves data transmission stability.

[0015] Compared with the existing method of adjusting the A5 measurement threshold or the minimum access level of the frequency band only on the network side, the present invention provides a more flexible and intelligent solution that can dynamically adjust the reselection priority according to the actual signal quality, thereby optimizing the user experience of the terminal while ensuring network performance.

[0016] The reselection priority compensation method based on the terminal signal quality measurement result, wherein, before the step of the terminal establishing a connection with the current serving cell base station and the current serving cell base station configuring a measurement task for the terminal connected to the current cell, the method includes:

[0017] The first trigger condition is preset as follows: the terminal determines that the frequency band of the current serving cell has the highest cell reselection priority;

[0018] The second trigger condition is preset as follows: the signal quality of the current serving cell measured by the terminal is lower than the first threshold set for the A5 event; the signal quality measurement result of the inter-frequency neighboring cell is higher than the second threshold of the A5 event, and the A5 event measurement report is triggered.

[0019] The reselection priority compensation method based on the terminal signal quality measurement result, wherein, before the step of the terminal establishing a connection with the current serving cell base station and the current serving cell base station configuring a measurement task for the terminal connected to the current cell, the method includes:

[0021] The reselection priority compensation method based on the terminal signal quality measurement result, wherein, when the terminal determines that the current serving cell frequency band has the highest reselection priority, the signal quality of the current serving cell and the inter-frequency neighboring cell is monitored; when the monitored signal quality of the current serving cell and the inter-frequency neighboring cell meets the preset trigger condition, the terminal is controlled to start the reselection priority compensation mechanism step:

[0022] When the terminal determines that the frequency band reselection priority of the current serving cell is the highest, and monitors that the signal quality of the current serving cell and the inter-frequency neighboring cell meets the preset trigger condition, the terminal controls the frequency band reselection priority of the current serving cell to be decremented;

[0023] Use counters and timers to control the frequency and magnitude of priority adjustments;

[0024] Set a timeout mechanism to restore the original priority when the conditions are no longer met.

[0026] Dynamic reselection priority compensation mechanism based on terminal signal quality measurement results;

[0027] Combine historical data and trend analysis of signal quality to smooth out sharp fluctuations in signal quality;

[0028] A signal quality change rate judgment mechanism is introduced to control the terminal to temporarily maintain the current priority when the signal changes drastically.

[0030] Set a minimum signal detection threshold in the terminal software;

[0031] When the detected actual signal is lower than the detection threshold, a virtual A5 event is automatically triggered to simulate the presence of a neighboring cell signal, thereby triggering a priority compensation mechanism.

[0032] The reselection priority compensation method based on the terminal signal quality measurement result, wherein, when the terminal determines that the current serving cell frequency band has the highest reselection priority, the signal quality of the current serving cell and the inter-frequency neighboring cell is monitored; when the monitored signal quality of the current serving cell and the inter-frequency neighboring cell meets the preset trigger condition, the step of controlling the terminal to start the reselection priority compensation mechanism includes:

[0033] Deeply optimize the reselection priority adjustment algorithm and set a silent period mechanism for terminals;

[0034] When a signal interruption is detected, the terminal enters a silent period and does not perform priority adjustment;

[0035] When the silent period ends, the current signal quality is judged and a decision is made as to whether priority adjustment should be made.

[0036] A reselection priority compensation device based on terminal signal quality measurement results, wherein the device includes:

[0037] A connection module is used to configure a measurement task for the terminal connected to the current serving cell base station when the terminal establishes a connection with the current serving cell base station;

[0038] A judgment module is used to control the terminal to determine whether the frequency band of the current serving cell has the highest reselection priority;

[0039] A reselection priority compensation start detection module is configured to monitor the signal quality of the current serving cell and the inter-frequency neighboring cell when the terminal determines that the current serving cell frequency band has the highest reselection priority; when the monitored signal quality of the current serving cell and the inter-frequency neighboring cell meets a preset trigger condition, control the terminal to start the reselection priority compensation mechanism; wherein the preset trigger condition is that the signal quality of the current serving cell is lower than the first threshold set by the A5 event, and the signal quality of the inter-frequency neighboring cell is higher than the second threshold of the A5 event, and an A5 event measurement report is triggered;

[0040] The first reselection priority compensation execution module is used to control the terminal to start the A5 measurement report counter and add 1 when the terminal starts the reselection priority compensation mechanism, and at the same time start the A5 measurement report timer and reduce the reselection priority of the frequency band of the current serving cell by 1:

[0041] The second reselection priority compensation execution module is configured to, when the terminal detects that the signal quality of the serving cell meets the preset trigger condition again before the expiration of the A5 measurement report timer, control the A5 measurement report timer to increase by 1 and the current serving cell frequency band reselection priority to decrease by 1; and after the data transmission service is completed, the terminal evaluates the candidate cells for reselection according to the new frequency band priority and completes cell reselection;

[0042] The compensation clearing module is used to control the A5 measurement report timer and the serving cell frequency band reselection priority to be compensated and cleared when the A5 measurement report timer times out.

[0043] An intelligent terminal includes a memory and one or more programs, wherein the one or more programs are stored in the memory and are configured to be executed by one or more processors, including the method for executing any one of the methods described above.

[0044] A computer-readable storage medium, wherein when instructions in the storage medium are executed by a processor of an electronic device, the electronic device is enabled to perform any one of the methods described above.

[0045] Beneficial effects of the present invention: The present invention provides a reselection priority compensation method, device, intelligent terminal and storage medium based on the terminal signal quality measurement results. Since the terminal is used to determine that the current service cell frequency band has the highest reselection priority, when the service cell signal quality is lower than the first threshold value set by the A5 event, the terminal starts to perform A5 event second threshold value measurement on the heterofrequency neighboring cell and triggers the A5 event measurement report. At this time, the terminal locally reselects the current service cell frequency band priority -1, and after the data transmission service is completed, the terminal reselects the candidate cell evaluation according to the new frequency band priority and completes the cell reselection.

[0046] The present invention dynamically adjusts the frequency band reselection priority by compensating for the frequency band reselection priority set by the terminal, thus circumventing the problem that the fixed frequency band reselection priority set by the network cannot solve the problem of cyclic switching and cell reselection between frequency bands caused by the signal quality of the high-priority frequency band being significantly lower than that of the low-priority frequency band. Existing technologies can only address this problem by adjusting the A5 measurement threshold or the minimum access level of the high-priority and low-priority frequency bands on the network side, which can cause the terminal to always reside on the high-priority or low-priority frequency band.

[0047] The present invention avoids frequent cell switching during data service transmission, avoids unnecessary signaling cycles, reduces signaling load, and improves data transmission stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments recorded in the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0049] Figure 1 This is a flow chart of a method for compensating a reselection priority based on a terminal signal quality measurement result provided in Example 1 of the present invention.

[0050] Figure 2 A principle block diagram of an embodiment of a reselection priority compensation device based on terminal signal quality measurement results provided by the present invention.

[0051] Figure 3 This is a block diagram of the internal structure of the smart terminal provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0052] In order to make the purpose, technical solutions and advantages of the present invention more clear and distinct, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0053] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0054] In existing networks, frequency band A is configured as a high-priority reselection band, indicating good coverage and ample bandwidth capacity. This makes it the primary frequency band for network deployment and the preferred frequency band for terminal data transmission. However, when a terminal is located in an area with weak signal quality in frequency band A, data transmission at this location cannot be guaranteed, and the terminal must switch to a frequency band with better service quality but a lower reselection priority. After data transmission is complete, the terminal will return to frequency band A, with its weaker signal quality, according to the frequency band reselection priority defined by the network. Furthermore, when the terminal initiates new data transmissions, it will still initiate an RRC connection in frequency band A, resulting in unnecessary signaling loops.

[0055] That is, in the existing technology, when the terminal is located at a location with weak signal quality in a high-priority frequency band, it will switch to a low-priority frequency band with better signal quality during data transmission, and return to the high-priority frequency band with weaker signal quality after the data transmission is completed, causing unnecessary signaling load and increased power consumption.

[0056] In response to the above problems, the present invention provides a reselection priority compensation method based on terminal signal quality measurement. The terminal determines that the current serving cell frequency band has the highest reselection priority. When the serving cell signal quality is lower than the first threshold set by the A5 event, the terminal starts to perform A5 event second threshold measurement on the heterofrequency neighboring cell and triggers the A5 event measurement report. At this time, the terminal locally reselects the current serving cell frequency band priority -1, and after the data transmission service is completed, the terminal reselects the candidate cell evaluation according to the new frequency band priority and completes the cell reselection.

[0057] This invention proposes a reselection priority compensation method based on terminal signal quality measurement results, aiming to address the frequent switching and reselection issues caused by fixed frequency band reselection priorities in the prior art. In the prior art, when a terminal is located in a high-priority frequency band with weak signal quality, it switches to a lower-priority frequency band with better signal quality during data transmission. After data transmission is complete, it returns to the higher-priority frequency band with weaker signal quality, resulting in unnecessary signaling overhead and increased power consumption.

[0058] like Figure 1 As shown, a reselection priority compensation method based on a terminal signal quality measurement result according to embodiment 1 of the present invention includes the following steps:

[0059] Step S100: When a terminal establishes a connection with a current serving cell base station, the current serving cell base station configures a measurement task for the terminal connected to the current cell;

[0060] The present invention relates to wireless communication systems, in particular to the interaction between user terminals and base stations in mobile communication networks (such as 4G or 5G).

[0061] Specifically, in this embodiment, when a mobile terminal (such as a smartphone) enters a serving cell (i.e., within the coverage area of ​​a base station) and establishes a connection with the base station, the base station assigns a measurement task to the terminal. This measurement task ensures that the terminal can continuously monitor signal strength and other relevant signal parameters in its surroundings. These parameters can include signal quality of neighboring cells, sector load, and signal interference.

[0062] In this way, the base station will assess the terminal's mobility status, channel conditions, and whether the terminal needs to switch (i.e., switch from the current base station to a neighboring base station). By regularly obtaining these measurement results, the network can efficiently manage resources and optimize service quality.

[0063] Step S200: The terminal determines whether the frequency band of the current serving cell has the highest reselection priority;

[0064] In the embodiment of this step, after determining the serving cell to be connected, the terminal evaluates whether the frequency band used by the serving cell has the highest reselection priority set by the terminal.

[0065] In mobile communication networks, base stations transmit and receive signals using different frequency bands (e.g., 800 MHz, 1800 MHz, 2600 MHz, etc.). Each frequency band may have different coverage, signal quality, and network load. Reselection priority is a mechanism used by terminals to determine when to switch from their current cell to another.

[0066] In the embodiment of the present invention, the terminal determines whether the frequency band used by the currently connected cell has the highest reselection priority based on preset rules and conditions. Specifically, it involves:

[0067] Frequency band characteristics: transmission performance of different frequency bands, such as coverage and penetration capability.

[0068] Signal strength: The signal strength and quality of the current serving cell.

[0069] Neighboring cells: The frequency bands used by other neighboring cells and their performance advantages.

[0070] If the frequency band of the current serving cell has the highest reselection priority, proceed to step S300.

[0071] In the embodiment of the present invention, by preferentially selecting the frequency band with the best signal quality, the terminal can obtain a more stable and clearer communication experience.

[0072] For example, consider a user using a mobile phone in a city. The user's phone is connected to a base station operating in the 1800MHz frequency band. Nearby, there are other cells operating in the 800MHz and 2600MHz frequency bands. The terminal detects the signal strength and quality of each frequency band and determines which frequency band has the highest reselection priority.

[0073] Step S300: When the terminal determines that the current serving cell frequency band has the highest reselection priority and the serving cell signal quality meets the preset trigger condition, the terminal is controlled to start the reselection priority compensation mechanism; wherein the preset trigger condition is that the current serving cell signal quality is lower than the first threshold set for the A5 event, and the inter-frequency neighbor cell signal quality is higher than the second threshold of the A5 event, and the A5 event measurement report is triggered;

[0074] In this embodiment, when the terminal determines that the frequency band of its current serving cell has the highest reselection priority and the signal quality of the cell is lower than a predetermined trigger condition, the system will initiate an operation called "reselection priority compensation mechanism".

[0075] Conditional judgment: The terminal must first reselect the cell with the highest priority. Specifically, the terminal must first confirm that the frequency band of the currently connected cell has the highest reselection priority among different cells. This means that among multiple cells, this cell has the first choice to provide service to the terminal.

[0076] However, the signal quality needs to meet the preset trigger conditions. Specifically, the terminal needs to detect the signal quality of the current cell to ensure that its signal quality is lower than the set threshold (first threshold), and at the same time check whether the signal quality of the inter-frequency neighboring cell closest to the terminal is higher than another set threshold (second threshold).

[0077] When all the above conditions are met, the terminal will start the compensation mechanism, which means that the terminal in the embodiment of the present invention will adjust its behavior and actively seek to connect to a neighboring cell with a stronger signal to ensure that the user can enjoy better communication quality.

[0078] The A5 event is essentially a mechanism for triggering cell reselection. When specific signal conditions are met, the terminal will send a measurement report.

[0079] For example, a user is using a smartphone in a commercial district of a city, currently connected to a base station. The base station is using a frequency band, such as 1800 MHz. The terminal detects that the signal strength in this frequency band is gradually decreasing, falling below a predefined first threshold (e.g., -95 dBm). Simultaneously, the terminal detects that the signal quality in a frequency band (e.g., 800 MHz) used by some neighboring cells is relatively good, exceeding a second threshold (e.g., -90 dBm).

[0080] In such a case, the terminal according to the embodiment of the present invention will start a reselection priority compensation mechanism, thereby improving the user experience.

[0081] The present invention starts a reselection priority compensation mechanism so that the terminal can respond to signal changes in real time and maintain communication stability.

[0082] Step S400: When the terminal starts the reselection priority compensation mechanism, the terminal is controlled to start the A5 measurement report counter and add 1, and at the same time start the A5 measurement report timer, and reduce the reselection priority of the frequency band of the current serving cell by 1:

[0083] In this embodiment of the present invention, when a mobile terminal determines that cell reselection is necessary and initiates the reselection priority compensation mechanism, a series of control steps are triggered to optimize communication quality. In this embodiment, the terminal starts the A5 measurement report counter and timer, and simultaneously adjusts the reselection priority of the current serving cell. This action not only reflects network conditions but is also a key step in improving user experience.

[0084] Specifically, regarding the start of the A5 measurement report counter, when the reselection priority compensation mechanism is activated, the terminal starts a counter specifically to record each A5 measurement report event. This includes measuring the signal quality of the current cell and neighboring cells, providing a basis for subsequent network selection. Increasing the counter by 1 indicates that the measurement event has been recorded, ensuring that the terminal can track changes in signal quality.

[0085] Regarding starting the A5 measurement report timer: The timer is started to set a time window during which the terminal will regularly measure signal quality. This mechanism ensures that the terminal continuously monitors the cell signal at a certain interval, so that it can promptly respond to changes in network conditions.

[0086] In the embodiment of the present invention, reducing the reselection priority of the current serving cell by 1 means that the terminal will reduce its dependence on the current cell. This strategy will prompt the terminal to consider the possibility of connecting to other cells with stronger signals during the next measurement evaluation.

[0087] This dynamic adjustment enables the terminal to respond more flexibly to environmental changes, ensuring that users are connected to the best possible network.

[0088] For example, a user is video chatting in a crowded shopping mall. The terminal connects to an 1800 MHz cell. Due to interference from surrounding buildings, the signal quality gradually degrades, falling below the first threshold. Simultaneously, the terminal detects a neighboring cell (for example, one using the 800 MHz band) with good signal quality exceeding the second threshold. At this point, the terminal initiates the reselection priority compensation mechanism and performs the following operations:

[0089] The counter is incremented by 1: This records the measurement event. Assume the initial value is 0 and becomes 1 after recording.

[0090] Timer Start: Signal quality monitoring begins and measurements are taken periodically over the next few seconds.

[0091] Reselection priority minus 1: The current 1800MHz cell reselection priority is reduced from high priority group 3 to low priority group 2, which means that the terminal will continue to detect the signal quality of other cells.

[0092] During the next monitoring cycle, the terminal detected continued strong signal quality in the 800MHz cell and decided to switch to that cell. The video call was transferred smoothly, with no interruption or noticeable delay for the user.

[0093] Through this mechanism, stable and high-quality network services can be obtained in complex mobile environments, improving overall user satisfaction.

[0094] It can be seen that in the embodiment of the present invention, after starting the counter and timer, the terminal can respond to signal changes more quickly instead of relying on a fixed measurement time, thereby improving adaptability to network conditions. It also reduces the reselection priority of the current cell, prompting the device to search for better signals more frequently, which can effectively reduce the system burden and optimize the allocation of network resources. Moreover, when making video calls, online games, or data streaming, which have high bandwidth requirements, quickly switching to a cell with a better signal can significantly improve the user experience and reduce disconnection rates and delays. It also has dynamic adjustment capabilities: by continuously monitoring and gradually adjusting the reselection priority, the terminal can maintain robustness in complex environments, ensuring that users are always connected to the best network.

[0095] Step S500: When the terminal detects that the signal quality of the serving cell meets the preset trigger condition again before the expiration of the A5 measurement report timer, the terminal controls the A5 measurement report timer to increase by 1 and the frequency band reselection priority of the current serving cell to decrease by 1; and after the data transmission service is completed, the terminal evaluates the candidate cells for reselection according to the new frequency band priority and completes the cell reselection;

[0096] In an embodiment of the present invention, before the A5 measurement report timer of the terminal expires, if it is detected that the signal quality of the serving cell again meets the preset trigger condition, that is, it is detected that the signal quality of the current serving cell is lower than the first threshold value set by the A5 event (for example, the signal strength is lower than -100dBm), and the signal quality of the adjacent inter-frequency cell is higher than the second threshold value set by the A5 event (for example, the signal strength is higher than -85dBm), and the A5 event measurement report has been triggered, it indicates that the current network environment has changed.

[0097] If the above conditions are met, the terminal will increment the A5 measurement report timer by 1 again, indicating that the terminal will continue to observe the current cell signal and hope that it will return to an acceptable level. At the same time, the frequency band reselection priority of the current serving cell will be decremented by 1 again, indicating that the terminal's dependence on the cell has further decreased.

[0098] Once the current data transmission task is completed, the terminal will evaluate the candidate cells for cell reselection based on the updated frequency band priority and select a cell with higher signal quality for connection to optimize the user's network experience.

[0099] For example, consider a user making a video call on their phone in a downtown skyscraper. Due to the building's structure, the base station signal to which the user's phone is connected gradually weakens, dropping to -105dBm (below the first threshold). Simultaneously, the user's phone detects a -80dBm signal strength from a neighboring inter-frequency cell downstairs (above the second threshold), triggering an A5 event.

[0100] At this point, the terminal performs the following steps:

[0101] Timer increment by 1: The terminal increments the A5 measurement report timer by 1, which means that it decides to continue monitoring the signal of the current cell.

[0102] Priority reduced by 1: The frequency band reselection priority of the current serving cell is reduced from 2 to 1, indicating that the terminal's dependence on the connection of this cell is reduced.

[0103] Post-Call Reselection: After a video call ends, the device evaluates available cells for handover. During this evaluation, it identifies a neighboring cell with stable and excellent signal strength. The phone then successfully switches to that cell, restoring a high-quality signal and enabling the user to continue their next call or data transmission.

[0104] Through this mechanism, users can maintain good service quality even in poor signal environments, achieving a consistent communication experience. This intelligent signal management also ensures overall network efficiency and avoids user experience degradation caused by frequent handoffs or weak signals.

[0105] It can be seen that the present invention, through continuous monitoring and dynamic adjustment, enables the terminal to respond to signal fluctuations more flexibly, thereby promptly discovering and connecting to cells with stronger signals, reducing the possibility of connection interruption. When the terminal can intelligently determine when to reduce its dependence on the current cell and quickly switch to a cell with a stronger signal, it can significantly reduce call interruptions and data transmission delays, ensuring the user's communication continuity. Moreover, when users use mobile devices, especially in scenarios such as video calls and online games that are sensitive to delays and connection quality, they can get a better experience and improve overall satisfaction. In addition, dynamically adjusting the cell reselection priority helps to more efficiently allocate network resources, avoid overload caused by concentration in a single cell, and improve the overall performance of the network.

[0106] Step S600: When the A5 measurement report timer times out, the A5 measurement report timer and the serving cell frequency band reselection priority compensation are controlled to be cleared.

[0107] In this step embodiment, when the terminal does not meet the conditions for triggering cell reselection within a certain period of time, the A5 measurement report timer reaches a preset timeout period, which means that the signal quality of the terminal in the current serving cell has not improved and no cell conducive to handover has been found.

[0108] Once the timer times out, the system will reset the A5 measurement report timer to zero and also clear the frequency band reselection priority of the current serving cell to zero.

[0109] Reset the timer to zero: Restart the calculation of the next measurement and evaluation cycle.

[0110] Reselection priority is cleared to zero: This means that the currently connected cell is no longer given priority and the system will re-evaluate possible connection options.

[0111] For example, a user in a remote area uses her mobile phone to play an online game. Initially, her phone connects to a cell with a signal strength of -90dBm. However, due to environmental changes (such as surrounding buildings or weather conditions), the signal quality gradually deteriorates to -110dBm, failing to meet the first threshold for cell reselection.

[0112] In this case, the phone's A5 measurement report timer starts counting and continuously monitors the signal quality and the conditions of nearby cells.

[0113] Timer timeout: After a period of time (for example, 10 seconds), the timer expires, but the signal is still not good and the switch is not triggered.

[0114] Reset operation: The timer is reset, indicating that the system will no longer maintain the connection based on the previous conditions. At the same time, the reselection priority of the current cell is also reset, which means that the terminal can start to re-evaluate the connection possibility of other surrounding cells.

[0115] Re-evaluate the cell: After clearing, the terminal performs a new round of cell scanning and finds that the signal strength of another nearby cell is -80dBm (higher than the set second threshold). The phone then quickly switches to this cell to ensure that the user's gaming experience is not affected.

[0116] This mechanism ensures that wireless terminals can flexibly adapt and quickly adjust network connections in complex and changing environments. By expiring timers and clearing priorities, terminals can more effectively identify and connect to cells with stronger signals, significantly improving the user experience and maintaining network service continuity and efficiency.

[0117] This step embodiment has the following advantages: 1) It can enhance network adaptability: because the current cell cannot provide stable signal quality and there is no improvement for a long time, the zeroing action can prompt the terminal to quickly switch to other cells with better signal quality. This mechanism helps the terminal adapt to the ever-changing network environment more flexibly. 2) It can improve switching efficiency: because the zeroing of the timer and the resetting of the frequency band reselection priority help the system reduce its dependence on poor connections, so that the terminal can search and switch cells more efficiently, avoiding disconnection or data delays caused by poor signals. 3) It can reduce user-perceived network problems: by quickly switching to a better cell, users can feel a smoother experience when using the service, reducing problems such as call quality degradation and video freezes. 4) It can optimize resource utilization: through timely and effective reselection, the network can allocate resources more reasonably, avoiding a cell with too much load from falling into resource shortage due to too many users.

[0118] In summary, the present invention effectively solves the problem caused by fixed frequency band reselection priorities through this dynamic adjustment mechanism. When the signal quality of a high-priority frequency band is significantly lower than that of a low-priority frequency band, the terminal can temporarily lower the reselection priority of the high-priority frequency band, thereby avoiding frequent switching and reselection operations. This not only reduces unnecessary signaling load, but also lowers terminal power consumption and improves data transmission stability.

[0119] Compared with the existing method of adjusting the A5 measurement threshold or the minimum access level of the frequency band only on the network side, the present invention provides a more flexible and intelligent solution that can dynamically adjust the reselection priority according to the actual signal quality, thereby optimizing the user experience of the terminal while ensuring network performance.

[0120] The method for compensating for reselection priority based on terminal signal quality measurement results of the present invention, before implementation, includes:

[0121] The first trigger condition is preset as follows: the terminal determines that the frequency band of the current serving cell has the highest cell reselection priority;

[0122] The second trigger condition is preset as follows: the signal quality of the current serving cell measured by the terminal is lower than the first threshold set for the A5 event; the signal quality measurement result of the inter-frequency neighboring cell is higher than the second threshold of the A5 event, and the A5 event measurement report is triggered.

[0123] The present invention is further described in detail below through a specific application example:

[0124] A reselection priority compensation method based on a terminal signal quality measurement result according to a specific application embodiment 2 of the present invention includes the following steps:

[0125] Step S11: The terminal first determines whether the frequency band of the current serving cell has the highest reselection priority. If the terminal determines that the frequency band of the current serving cell has the highest cell reselection priority, it proceeds to step S12.

[0126] Step S12: When the following conditions are met, the terminal starts a reselection priority compensation mechanism:

[0127] a) The signal quality of the current serving cell is lower than the first threshold set for event A5.

[0128] b) The signal quality of the inter-frequency neighboring cell is higher than the second threshold of the A5 event, and triggers the A5 event measurement report.

[0129] Step S13: After the compensation mechanism is triggered, the terminal performs the following operations:

[0130] a) Start the A5 measurement report counter and increment it by 1.

[0131] b) Start the A5 measurement report timer.

[0132] c) Decrease the reselection priority of the frequency band where the current serving cell is located by 1.

[0133] Step S14: If the trigger condition is met again before the A5 measurement report timer expires, then:

[0134] a) The A5 measurement report counter is incremented by 1 again.

[0135] b) The frequency band reselection priority of the current serving cell is reduced by 1 again.

[0136] Step S15: If the A5 measurement report timer times out, the A5 measurement report counter and the serving cell frequency band reselection priority compensation are cleared.

[0137] As can be seen above, this dynamic adjustment mechanism effectively solves the problem caused by fixed frequency band reselection priorities. When the signal quality of a high-priority frequency band is significantly lower than that of a low-priority frequency band, the terminal can temporarily lower the reselection priority of the high-priority frequency band, thereby avoiding frequent switching and reselection operations. This not only reduces unnecessary signaling load, but also lowers terminal power consumption and improves data transmission stability.

[0138] Compared with the existing method of adjusting the A5 measurement threshold or the minimum access level of the frequency band only on the network side, the present invention provides a more flexible and intelligent solution that can dynamically adjust the reselection priority according to the actual signal quality, thereby optimizing the user experience of the terminal while ensuring network performance.

[0139] Furthermore, a specific application embodiment of the present invention provides a reselection priority compensation method based on terminal signal quality measurement results, which adopts a dynamic reselection priority compensation mechanism based on terminal signal quality measurement results. Specifically, the method involves determining whether the frequency band of the current serving cell has the highest reselection priority, and monitoring the signal quality of the serving cell and inter-frequency neighboring cells. When the triggering conditions are met (i.e., the signal quality of the current serving cell is lower than the first threshold set by the A5 event, and the signal quality of the inter-frequency neighboring cell is higher than the second threshold set by the A5 event, and an A5 event measurement report is triggered), the reselection priority compensation mechanism is activated, and then the A5 measurement report counter and timer are used to control the compensation process; and the reselection priority of the frequency band of the serving cell is dynamically adjusted.

[0140] For example, the terminal determines whether the frequency band reselection priority of the current serving cell is the highest by receiving the SIB2 and SIB4 messages of the serving cell. The terminal continuously measures the signal quality of the current serving cell and the inter-frequency neighboring cell. When the signal quality of the serving cell is lower than the first threshold of the A5 event (such as -110dBm), and the signal quality of the inter-frequency neighboring cell is higher than the second threshold of the A5 event (such as -90dBm), the A5 event measurement report is triggered. After the trigger, the terminal starts the A5 measurement report counter and adds 1, and starts the A5 measurement report timer (such as set to 30 seconds), and reduces the frequency band reselection priority of the current serving cell by 1. If the trigger condition is met again before the timer expires, the counter is increased by 1 again and the priority is reduced by 1 again. If the timer times out, the counter and priority compensation are cleared.

[0141] The benefit of this approach is that it prevents terminals from frequently switching and reselecting between high- and low-priority frequency bands with significantly different signal qualities. It also reduces unnecessary signaling overhead, lowering network resource consumption; lowering terminal power consumption, extending battery life; improving data transmission stability and user experience; and providing a more flexible and intelligent network access method compared to fixed priority policies.

[0142] Furthermore, a specific application embodiment of the present invention provides a reselection priority compensation method based on terminal signal quality measurement results, which utilizes an A5 event-based trigger condition. Specifically, the A5 event serves as the trigger condition for reselection priority compensation. The A5 event includes two key thresholds: the lower limit of the serving cell signal quality and the upper limit of the inter-frequency neighboring cell signal quality. The coordination of these two thresholds ensures that the compensation mechanism is triggered only when necessary.

[0143] For example, the network configures the parameters for the A5 event: the first threshold (serving cell) is set to -110dBm, and the second threshold (inter-frequency neighboring cell) is set to -90dBm. The terminal then continuously measures the signal quality of the serving cell and inter-frequency neighboring cells. When the serving cell signal quality drops below -110dBm while the inter-frequency neighboring cell signal quality rises above -90dBm, the A5 event is triggered. After the A5 event is triggered, the terminal performs reselection priority compensation.

[0144] This allows precise control over the triggering timing of the compensation mechanism, avoiding overly frequent or delayed compensation. It also ensures that priority adjustment occurs only when the serving cell's signal quality is significantly worse than that of a neighboring cell with a different frequency. Furthermore, by properly setting thresholds, it balances network performance and user experience. This is compatible with the existing A5 event measurement mechanism, making it easy to implement in existing systems.

[0145] Furthermore, a specific embodiment of the present invention employs a reselection priority compensation method based on terminal signal quality measurement results, employing a dynamic reselection priority adjustment algorithm. The implementation process may include the following steps: initially determining whether the current serving cell frequency band has the highest reselection priority. If it has the highest reselection priority and trigger conditions are met, decrementing the reselection priority of the current serving cell frequency band; using a counter and timer to control the frequency and magnitude of priority adjustments; and setting a timeout mechanism to restore the original priority when the conditions are no longer met.

[0146] For example, the terminal confirms through SIB2 and SIB4 messages that the current frequency band has the highest reselection priority (e.g., a priority value of 7). When the A5 event trigger condition is met, the priority value is reduced by 1 (to 6). A 30-second timer is started. If it is triggered again before the timer expires, the priority value is reduced by 1 again (to 5). If it is not triggered again before the timer expires, or if the timer expires, the priority value is restored to the initial value (7).

[0147] This allows for dynamic and progressive adjustment of frequency band reselection priorities, avoiding unnecessary priority adjustments due to single measurement errors. Multi-level adjustments can also accommodate varying degrees of signal quality. This invention also incorporates a recovery mechanism to ensure the long-term maintenance of the planned network priority strategy. The algorithm is simple and efficient, easily implemented in terminal devices, and requires minimal processing resources.

[0148] A method for compensating a reselection priority based on a terminal signal quality measurement result according to embodiment 3 of the present invention includes the following steps:

[0149] The first trigger condition 1 is pre-set: the terminal determines that the frequency band of the current serving cell has the highest cell reselection priority;

[0150] The second trigger condition 2 is pre-set: the signal quality of the current serving cell measured by the terminal is lower than the first threshold set for the A5 event; the signal quality measurement result of the inter-frequency neighboring cell is higher than the second threshold of the A5 event, and the A5 event measurement report is triggered;

[0151] Among them, in the A5 event, the mobile phone measures that the signal of the current serving cell is worse than the set threshold value, while the signal of the neighboring cell is better than the set threshold value, and then reports the result to the current serving cell.

[0152] Step S1: The terminal starts the A5 measurement report counter and adds 1, starts the A5 measurement report timer at the same time, and reselects the frequency band where the current serving cell is located with a priority of -1.

[0153] Step S2: If the terminal detects that condition 2 is met again before the expiration of the A5 measurement report timer, the A5 measurement report timer is increased by 1 and the current serving cell frequency band reselection priority is decreased by 1.

[0154] Step S3: If the A5 measurement report timer times out, the A5 measurement report timer and the serving cell frequency band reselection priority compensation are cleared.

[0155] The present invention mainly provides a reselection priority compensation method based on the terminal signal quality measurement results. When the terminal determines that the frequency band where the current service cell is located has the highest reselection priority, and the network is configured with an A5 measurement event for the frequency band to which the current service cell belongs and the frequency band to which the adjacent cell belongs, and the measured signal quality of the reselected high-priority frequency band is less than the signal quality of the low-priority frequency band and exceeds the set threshold, the priority of the reselected high-priority frequency band will be reduced to -1, and after the above conditions are not met and timeout occurs, the reselection priority compensation function will be turned off and the frequency band reselection priority compensation will be reset.

[0156] A method for compensating a reselection priority based on a terminal signal quality measurement result, as described in Embodiment 3 of the present invention, includes the following specific implementation steps:

[0157] S21: The terminal determines that the frequency band of the current serving cell has the highest frequency band reselection priority based on the frequency band reselection priority in the received SIB2 and SIB4 messages of the serving cell;

[0158] S22: The signal quality of the current serving cell measured by the terminal is lower than the first threshold set by the A5 event; the signal quality measurement result of the inter-frequency neighboring cell is higher than the second threshold of the A5 event, and the A5 event measurement report is triggered.

[0159] S23: The terminal starts the A5 measurement report counter and adds 1, starts the A5 measurement report timer at the same time, and reselects the priority of the current serving cell frequency band -1.

[0160] S24: If the terminal detects that condition 2 is met again before the A5 measurement report timer expires, the A5 measurement report timer is increased by 1 and the current serving cell frequency band reselection priority is decreased by 1.

[0161] S25: If the A5 measurement report timer times out, the serving cell frequency band reselection priority compensation is cleared.

[0162] As can be seen from the above, the embodiment of the present invention dynamically adjusts the frequency band reselection priority by compensating the frequency band reselection priority set by the terminal, thereby avoiding the problem that the fixed frequency band reselection priority set by the network cannot solve the problem of cyclic switching between frequency bands and cell reselection caused by the signal quality of the high-priority frequency band being significantly lower than that of the low-priority frequency band. The existing technology can only address this problem by adjusting the A5 measurement threshold or the minimum access level of the high-priority frequency band and the low-priority frequency band on the network side, which will cause the terminal to always reside in the high-priority frequency band or the low-priority frequency band.

[0163] Of course, the key point in the embodiment of the present invention is to determine whether the terminal continuously switches and reselects between the high-priority frequency band and the low-priority frequency band. The judgment conditions are not limited to the A5 event measurement report, but can also be an inter-frequency switching event or an inter-frequency reselection event, or the number of changes between the high-priority frequency band and the low-priority frequency band within a fixed time.

[0164] In a further embodiment, the method for compensating for reselection priority based on terminal signal quality measurement results according to an embodiment of the present invention further includes the following steps:

[0165] Regarding the dynamic reselection priority compensation mechanism based on terminal signal quality measurements, in high-density urban environments, terminals face the challenge of experiencing significant signal quality fluctuations due to building reflections and multipath effects. Signal fluctuations trigger frequent priority adjustments, leading to unnecessary frequency switching.

[0166] To address this issue, the terminal's measurement and decision-making mechanisms can be further optimized. Specifically, by combining historical signal quality data and trend analysis, dramatic fluctuations in signal quality can be smoothed out, reducing the priority adjustments caused by transient fluctuations. By introducing a mechanism that determines the rate of change in signal quality, the terminal can temporarily maintain its current priority level when the signal fluctuates dramatically, avoiding unnecessary handoffs.

[0167] In a further embodiment, the method for compensating for reselection priority based on terminal signal quality measurement results according to an embodiment of the present invention further includes the following steps:

[0168] In this embodiment, based on the triggering condition design of the A5 event, in closed environments such as subway tunnels, the terminal may not be able to continuously receive signals from neighboring cells with different frequencies, resulting in the A5 event not being triggered normally. To address this issue, a virtual signal source simulation mechanism can be introduced in the terminal to ensure that the terminal can still make necessary priority adjustments even in closed environments. Specific technical details include setting a minimum signal detection threshold in the terminal software. When the actual signal falls below this threshold, a virtual A5 event is automatically triggered, thereby simulating the presence of a neighboring cell signal and triggering the priority compensation mechanism.

[0169] In a further embodiment, the method for compensating for reselection priority based on terminal signal quality measurement results according to an embodiment of the present invention further includes the following steps:

[0170] Regarding the dynamic reselection priority adjustment algorithm in this embodiment, for example, in application scenarios with uneven signal coverage, such as rural or mountainous areas, intermittent signal coverage interruptions can cause frequent priority resets and restorations. To improve this situation, the reselection priority adjustment algorithm can be deeply optimized, specifically by introducing a silent period mechanism for the terminal. When the signal is interrupted, the terminal enters a silent period and no priority adjustment is performed. After the silent period ends, the decision on whether to adjust the priority is made based on the current signal quality. This effectively reduces unnecessary priority resets caused by signal interruptions and reduces terminal power consumption.
