[0085] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0086] Reference Figure 1 , shows a step flow chart of a voice service anti-interference method provided in an embodiment of the present invention, which is applied to a terminal, and the terminal establishes channel communication with a base station through a high-speed rail network based on 5GNR.

[0087] In a specific implementation, the high-speed rail network can be applied to the high-speed rail scenario, mainly used to provide high-speed, stable, and low-latency wireless communication networks for high-speed rail passengers. The high-speed rail network can adopt 5GNR technology (5G New Radio, the fifth generation of new radio access technology), which can provide passengers with faster data transmission services. When the user is on a high-speed rail train, the terminal held by the user can establish a channel with the base station therein through the high-speed rail network for communication.

[0088] The method may specifically include the following steps:

[0089] Step 101, receiving signal strength and signal-to-noise ratio sent by a base station according to a preset period;

[0090] In a specific implementation, in order to evaluate the communication quality between the base station and the terminal, the terminal may receive the signal strength and signal-to-noise ratio sent by the base station according to a preset period.

[0091] Specifically, multiple signal strengths and signal-to-noise ratios can be received within the preset period, and the frequency at which the base station sends the signal strength and signal-to-noise ratio within the preset period can be determined according to actual needs, and the present invention does not limit this.

[0092] Among them, the signal strength and signal-to-noise ratio may be for the terminal. In the high-speed rail scenario, the terminal may move quickly, thereby constantly switching the base station with which it communicates. As a result, the signal strength and signal-to-noise ratio received by the terminal may come from multiple base stations. The signal strength and signal-to-noise ratio that the terminal can receive according to a preset period may come from multiple base stations.

[0093] The signal strength (Received Signal Strength Indicator, RSSI) may refer to the power level of the wireless signal received by the terminal. The base station may determine the signal strength sent by the terminal device based on the power level of the signal sent by the received terminal device.

[0094] The signal-to-noise ratio (SNR) may refer to the ratio of the power levels between the signal received by the terminal and the background noise. The base station may determine the signal-to-noise ratio based on the ratio between the signal power and the background noise power in the signal sent by the receiving terminal device.

[0095] The base station can use a preset period to detect the signal strength and signal-to-noise ratio of the terminal accessing itself to determine whether the terminal has entered the base station with good quality. The detected signal strength and signal-to-noise ratio are sent to the terminal, so that the terminal can know its current signal strength and signal-to-noise ratio.

[0096] Step 102, determining an actual channel quality feedback index of the terminal according to the signal strength and signal-to-noise ratio;

[0097] Thereafter, for any period, the terminal may use the received signal strength and signal-to-noise ratio to determine an actual channel quality feedback indicator corresponding to the period.

[0098] In a specific implementation, the actual channel quality feedback indicator may be an indicator associated with signal strength and signal-to-noise ratio, such as a channel quality indicator (CQI), a block error rate (BLER), a link quality indicator (LQI), or other indicators associated with signal strength and signal-to-noise ratio, and the present invention is not limited thereto.

[0099] Step 103, determining a channel quality coefficient of the channel based on the actual channel quality feedback indicator;

[0100] In a specific implementation, after obtaining the actual channel quality feedback indicators under different periods, the channel quality coefficient of the channel between the current terminal and the base station can be further determined based on the actual channel quality feedback indicators under different periods to determine whether the current terminal communicates with the channel quality that meets the voice service requirements in the high-speed rail scenario, thereby maintaining the terminal's voice service with good anti-interference capability.

[0101] Specifically, a target channel quality feedback indicator may be set. The target information quality feedback indicator may be associated with the quality that the terminal expects to achieve in meeting the voice service quality requirement. The actual channel quality feedback indicator may be compared with the target channel quality feedback indicator, so that it may be determined whether the current actual channel quality feedback indicator can meet the voice service quality requirement based on the comparison result, and the channel quality coefficient of the channel may be obtained.

[0102] Step 104, determining a target transmission power based on neighboring terminal interference and the channel quality coefficient, and sending the target transmission power to the base station;

[0103] If the channel quality coefficient of the current terminal is not good, you can consider adjusting the terminal's transmit power to improve the terminal's channel quality so that the terminal can have better anti-interference ability for voice services. However, since the density of terminals in the high-speed rail network may be high, there may be overlap of spectrum resources between adjacent terminals. If the current terminal increases its own transmit power, it may cause interference to other adjacent terminals. Therefore, it is necessary to determine a reasonable target transmit power based on the consideration of both the interference of adjacent terminals and the channel quality coefficient. This can improve the channel quality of the current terminal while avoiding causing significant interference to adjacent terminals, thereby improving the terminal's anti-interference ability for voice services.

[0104] Step 105: If confirmation information returned by the base station regarding the target transmit power is received, the transmit power of the terminal is adjusted to the target transmit power to maintain the voice service anti-interference capability of the terminal.

[0105] After confirming the target transmit power, the terminal can send the target transmit power to the base station. The base station determines whether it is acceptable for the terminal to increase the transmit power based on the network capacity and spectrum resources of the current high-speed rail network. If acceptable, confirmation information can be returned for the target transmit power.

[0106] The terminal can adjust the transmit power to the target transmit power, thereby maintaining the terminal's voice service anti-interference capability at a better level and preventing the terminal's transmit power adjustment from causing adverse effects on neighboring terminals.

[0107] Through the voice service anti-interference method provided in the embodiment of the present invention, the signal strength and signal-to-noise ratio sent by the base station according to the preset period are received; according to the signal strength and signal-to-noise ratio, the actual channel quality feedback index of the terminal is determined; based on the actual channel quality feedback index, the channel quality coefficient of the channel is determined; based on the interference of the neighboring terminal and the channel quality coefficient, the target transmission power is determined and sent to the base station; if the confirmation information returned by the base station for the target transmission power is received, the transmission power of the terminal is adjusted to the target transmission power. In this way, the voice service anti-interference capability of the terminal can be kept at a better level, while avoiding the adverse effects of the terminal's transmission power adjustment on the neighboring terminals. At the same time, whether the terminal is allowed to adjust the transmission power is confirmed by the base station to avoid the terminal adjusting the transmission power and affecting the network environment of the current high-speed rail network.

[0108] In an embodiment of the present invention, the step of determining the actual channel quality feedback indicator of the terminal according to the signal strength and the signal-to-noise ratio includes:

[0109] S11, for signal strength and signal-to-noise ratio sent in different periods, respectively calculate the actual channel quality feedback index corresponding to the period to obtain an actual channel quality feedback index matrix; wherein the actual channel quality feedback index matrix contains at least one element, and the element is the actual channel quality feedback index of different periods.

[0110] In a specific implementation, the actual channel quality feedback index corresponding to the period can be calculated for the signal strength and signal-to-noise ratio sent in different periods. Thereafter, the actual channel quality feedback index corresponding to the different periods can be formed into an actual channel quality feedback index matrix.

[0111] The elements in the actual channel quality feedback indicator matrix may be actual channel quality feedback indicators of different periods.

[0112] Specifically, the rows of the actual channel quality feedback indicator matrix may represent a period, and the columns may represent the order in which the actual channel quality feedback indicators are obtained within the period.

[0113] Specifically, in order to improve the accuracy of the actual channel quality feedback indicator matrix, before forming the actual channel quality feedback indicator matrix, at least one maximum value and at least one minimum value can be screened out from the actual channel quality feedback indicators corresponding to different periods, and then the actual channel quality feedback indicator matrix is ​​formed based on the screened actual channel quality feedback indicators.

[0114] By continuously receiving actual channel quality feedback indicators for several cycles, screening out outliers and constructing an actual channel quality feedback indicator matrix, we can capture the changing trend of channel quality, make the analysis results of channel quality more representative and stable, and better adapt to channel changes in the high-speed rail environment.

[0115] In one embodiment of the present invention, the step of determining the channel quality coefficient of the channel based on the actual channel quality feedback indicator includes:

[0116] S21, calculating a channel quality coefficient of the channel based on elements in the actual channel quality feedback indicator matrix.

[0117] Specifically, based on the actual channel quality feedback indicator matrix T, the channel quality coefficient ξ is calculated Γ , expressed as:

[0118]

[0119] Among them, k is a preset real number, e is a natural constant, Γ mij is the element in the actual channel quality feedback indicator matrix T, Γ m is the target channel quality indicator, i represents the row in the actual channel quality feedback indicator matrix T, that is, the period corresponding to the actual channel quality feedback indicator, I represents the total number of periods, j represents the column in the actual channel quality feedback indicator matrix T, that is, the arrangement order of the actual channel quality feedback indicator in the current period, J represents the total number of actual channel quality feedback indicators in the period, and α is the preset channel quality coefficient modulation factor.

[0120] In a specific implementation, the preset real number k and the channel quality coefficient modulation factor α can be adjusted according to specific scenarios and requirements, which makes the calculation formula more flexible and can balance channel quality and power control according to actual conditions to achieve better voice service quality.

[0121] In one embodiment of the present invention, the step of determining the target transmission power based on the neighboring terminal interference and the channel quality coefficient and sending the target transmission power to the base station includes:

[0122] S31, determining a target adjustment method of the transmit power of the terminal according to the channel quality coefficient and a preset channel quality coefficient range; wherein the target adjustment method includes any one of increasing the transmit power, maintaining the current transmit power, and reducing the transmit power;

[0123] S32, determining a transmission power constraint condition of the terminal based on interference from neighboring terminals and a power requirement of the voice service;

[0124] S33, using the power constraint condition, adjusting the transmission power according to the target adjustment method, obtaining the target transmission power and sending it to the base station.

[0125] In a specific implementation, the channel quality coefficient range may refer to a range in which a terminal can obtain a better voice service quality. The channel quality coefficient may be compared with the channel quality coefficient range to determine whether the transmit power of the terminal needs to be adjusted.

[0126] The target adjustment method of the terminal's transmit power may include any one of increasing the transmit power, maintaining the current transmit power, and reducing the transmit power. If the current channel quality of the terminal is not good, it is necessary to consider increasing the transmit power of the terminal. If the current channel quality of the terminal is good, it is not necessary to adjust the transmit power and maintain the current transmit power. If the current channel quality of the terminal is too good, in order to avoid the terminal from excessively affecting other nearby terminals, the transmit power of the terminal can be reduced according to actual needs.

[0127] After determining the terminal adjustment mode, the terminal transmission power constraint condition can be further determined based on the interference of neighboring terminals and the power requirement of the voice service, so as to maintain good voice service quality of the terminal while avoiding the terminal affecting other neighboring terminals.

[0128] Thereafter, the power constraint condition may be used to adjust the transmit power in accordance with the target adjustment method, and a reasonable target transmit power may be obtained and sent to the base station to confirm whether adjustment according to the target transmit power is allowed, thereby achieving effective management and optimization of power resources.

[0129] In a specific implementation, the target transmission power is fed back to the base station in a manner including but not limited to physical layer feedback, MAC layer feedback, uplink control channel feedback and modulation mode feedback.

[0130] Among them, the physical layer feedback can embed the transmission power control information into the communication signal and transmit it through the set physical layer protocol. After receiving the feedback information, the base station adjusts the transmission power of the terminal.

[0131] The MAC layer feedback may send transmit power feedback information to the base station via a control frame, which involves defining a specific message type or field in the MAC layer protocol for transmitting power control information.

[0132] Uplink control channel feedback can use the uplink control channel to send power feedback information to the base station. In wireless communication systems such as LTE, a dedicated uplink control channel is usually defined for transmitting control information, including power control information.

[0133] Modulation mode feedback indirectly reflects the transmission power by adjusting the modulation mode of the transmitted signal. In the case of low signal-to-noise ratio, the terminal can choose a higher modulation mode to increase the data transmission rate, while in the case of high signal-to-noise ratio, it may reduce the modulation mode to reduce the bit error rate, thereby indirectly adjusting the transmission power.

[0134] In an embodiment of the present invention, the step of determining the adjustment method of the transmit power of the terminal according to the channel quality coefficient and the preset channel quality coefficient range includes:

[0135] S41, if the channel quality coefficient is lower than the minimum value in the channel quality coefficient range, determining that the transmission power of the terminal is adjusted in a manner of increasing the transmission power;

[0136] S42, if the channel quality coefficient is within the channel quality coefficient range, determining that the transmission power of the terminal is adjusted in a manner of maintaining the current transmission power;

[0137] S43: If the channel quality coefficient is higher than the maximum value in the channel quality coefficient range, determine that the transmission power of the terminal is adjusted in a manner of reducing the transmission power.

[0138] In a specific implementation, if the channel quality coefficient is lower than the minimum value in the channel quality coefficient range, it can be considered that the current channel quality of the terminal is poor. At this time, it is necessary to consider increasing the terminal's transmit power, so the terminal's transmit power is adjusted to increase the transmit power.

[0139] If the channel quality coefficient is within the channel quality coefficient range, it can be considered that the current channel quality of the terminal is good, and the transmission power does not need to be adjusted, but the current transmission power is maintained. Thus, the transmission power of the terminal can be adjusted to maintain the current transmission power.

[0140] If the channel quality coefficient is higher than the maximum value in the channel quality coefficient range, it can be considered that the current channel quality of the terminal is too good. In order to avoid excessive impact of the terminal on other adjacent terminals, the terminal's transmit power can be reduced according to actual needs. Thus, the terminal's transmit power can be adjusted by reducing the transmit power.

[0141] By comparing the relationship between the channel quality coefficient and the channel quality coefficient range, it is possible to determine whether the terminal's transmit power needs to be adjusted based on the actual channel quality and the preset channel quality coefficient range. This helps maintain the overall stability of the high-speed rail network and prevent drastic changes in transmit power from having an adverse effect on the performance of the high-speed rail network. At the same time, the target transmit power is fed back to the base station, which can further instruct the terminal to adjust its power, thereby achieving effective management and optimization of power resources.

[0142] In one embodiment of the present invention, the step of determining the transmit power constraint condition of the terminal based on the neighboring terminal interference and the power requirement of the voice service includes:

[0143] S51, determining a quality degradation coefficient based on interference from neighboring terminals;

[0144] S52, determining a first constraint condition for the neighboring terminal according to the quality degradation coefficient, a preset neighboring minimum transmission power, and a preset neighboring current transmission power;

[0145] S53, determining a second constraint condition for the terminal according to a preset minimum transmit power and a preset target quality transmit power;

[0146] S54: Use the first constraint condition and the second constraint condition as the transmission power constraint condition of the terminal.

[0147] Specifically, the quality degradation coefficient may be analyzed and determined based on the interference caused by the current terminal's transmit power change on the neighboring terminal, so as to determine the interference degree caused by the current terminal's transmit power change on the neighboring terminal.

[0148] Subsequently, in order to keep the neighboring terminal in a good state, the first constraint condition for the neighboring terminal can be determined based on the quality degradation coefficient, the preset neighboring minimum transmission power, and the preset neighboring current transmission power, thereby avoiding excessive adverse effects on the neighboring terminal caused by the terminal changing the transmission power.

[0149] At the same time, the second constraint condition for the terminal may be determined according to the preset minimum transmit power and the preset target quality transmit power, so as to determine the range of the terminal's own appropriate transmit power.

[0150] The first constraint condition and the second constraint condition may be used as the transmit power constraint condition of the terminal, so that the terminal can avoid interfering with neighboring terminals while maintaining the quality of its own voice service as much as possible.

[0151] Specifically, the transmission power constraint condition can be expressed in the following manner:

[0152]

[0153] Among them, fmin is the minimum transmission power for the terminal to normally carry out 5GNR voice services, ΔΨ fd is the first buffer amount when the terminal adjusts the transmit power, ΔΨ fg The second buffer amount when the terminal adjusts the transmission power, Ψ fm To achieve the target channel quality index Γ for the terminal m The target quality transmission power at flmin The minimum transmission power for the adjacent terminal to normally perform 5GNR voice services, Ψ fl is the neighboring current transmission power of the neighboring terminal, and p is the quality reduction coefficient of the current target channel of the neighboring terminal affected by the terminal transmission power.

[0154] In the embodiment of the present invention, the constraint condition Ψ flmin It ensures the minimum transmission power of the terminal when performing normal 5GNR voice services, which can ensure that the terminal can maintain basic communication capabilities under any circumstances and avoid communication interruption or quality degradation caused by weak signals. fd and ΔΨ fg It represents the first buffer amount and the second buffer amount of the terminal when adjusting the transmission power. The setting of the buffer amount can balance the stability and response speed of the terminal during the power adjustment process, and avoid the adverse effect of frequent power adjustment on system performance.

[0155] Ψ in the constraint fm It is the target quality transmission power when the terminal reaches the target channel quality index Γ_m. By setting this constraint, it can be ensured that the terminal transmission power is sufficient to meet the required channel quality requirements, thereby improving the quality and reliability of voice services.

[0156] Ψ in the constraint flmin and fl It is used to control the transmission power of neighboring terminals. It takes into account the coefficient p of the decrease in the neighboring terminals due to the influence of the terminal transmission power. It can avoid the channel quality degradation and mutual interference of neighboring terminals caused by excessive terminal transmission power, thereby reducing the interference problem in the system.

[0157] By setting these constraints, the terminal transmit power can be adjusted within a certain range, which can ensure the stability and reliability of the system while avoiding excessive interference with adjacent terminals. This can optimize channel quality, reduce interference, and improve the quality and reliability of voice services, thereby providing better user experience and network performance.

[0158] In one embodiment of the present invention, the step of determining the quality degradation coefficient based on the neighboring terminal interference includes:

[0159] S61, according to a preset interference detection cycle, increasing a preset first power variation amount on a current transmission power of the terminal period by period;

[0160] S62, for different interference detection cycles, respectively detecting a second power change amount of the transmission power of the neighboring terminal to determine interference to the neighboring terminal caused by the change of the transmission power of the terminal;

[0161] S63: Determine a quality degradation coefficient according to the first power change, the second power change, and a preset adjacent allowable change.

[0162] In a specific implementation, the identifier of the neighboring terminal may be obtained, and the first power variation ΔΨ of the terminal transmission power may be periodically adjusted according to the preset interference detection period. f Increase, and receive the second power change ΔΨ of the transmission power of the neighboring terminal at periodic intervals fl , to determine the interference caused by the terminal changing its transmission power to the neighboring terminals.

[0163] Then, the received multiple reduction amounts ΔΨ fl After normalization and quantitative ΔΨ f Perform fitting to obtain the drop coefficient p, the calculation formula is as follows:

[0164]

[0165] Among them, the correction factor θ, ΔΨ fy It is the transmission power change amount allowed by the neighboring terminal when the terminal transmission power is increased, that is, the neighboring allowed change amount.

[0166] The reduction coefficient p is used to measure the degree of reduction of the current target channel quality index of the neighboring terminal when it is affected by the terminal's transmit power. By obtaining the identifier of the neighboring terminal and increasing the terminal's transmit power periodically, and then receiving the reduction in the neighboring terminal's transmit power, the degree of interference to the neighboring terminal during the terminal power adjustment process can be quantitatively measured, which helps the terminal to more comprehensively consider the impact of the neighboring terminal when adjusting the transmit power, thereby reducing interference to the neighboring terminal and improving the quality and reliability of voice services.

[0167] By reducing the amount ΔΨ received fl Normalized and compared with ΔΨ f The fitting is performed to calculate the reduction coefficient p. This fitting method based on actual observation data makes the calculated reduction coefficient p more accurate and reliable. The reduction coefficient p obtained by fitting can better reflect the response characteristics of the neighboring terminals during the terminal power adjustment process, and provide a more accurate reference for the terminal power adjustment.

[0168] In addition, the correction factor θ and the allowable reduction in transmit power ΔΨ of the neighboring terminal when the terminal transmit power increases are considered. fy When calculating the reduction coefficient p, the constraints of power adjustment and the tolerance of neighboring terminals can be comprehensively considered. This calculation method that considers the constraints makes the power adjustment of the terminal more in line with the actual network environment and the needs of neighboring terminals, which helps to reduce unnecessary impacts on neighboring terminals and improve the coordination and overall performance of the network.

[0169] In an embodiment of the present invention, the step of determining the second constraint condition for the terminal according to the preset minimum transmit power and the preset target quality transmit power includes:

[0170] S71, determining a minimum constraint power according to a preset minimum transmission power and a first buffer amount;

[0171] S72, determining a maximum constrained power according to a preset target quality transmission power and a second buffer amount;

[0172] S73: Determine a second constraint condition for the terminal according to the minimum constraint power and the maximum constraint power.

[0173] In a specific implementation, the minimum constraint power is determined according to the preset minimum transmission power and the first buffer amount; the maximum constraint power is determined according to the preset target quality transmission power and the second buffer amount; and the second constraint condition for the terminal is determined according to the minimum constraint power and the maximum constraint power. Thus, when the terminal adjusts the transmission power, the first buffer amount and the second buffer amount can be dynamically adjusted according to the difference between the actual channel quality and the minimum and maximum channel quality indicators, ensuring the matching of the buffer amount with the normal channel quality range of the terminal, and improving the accuracy and reliability of power adjustment.

[0174] In one embodiment of the present invention, the method further comprises:

[0175] S81, determining a first buffer amount based on the elements in the actual channel quality feedback indicator matrix and the minimum transmit power;

[0176] The first buffer amount ΔΨ when the terminal adjusts the transmission power fd The minimum transmit power Ψ when the element in the matrix T is used and the minimum channel quality index of the terminal for normal 5GNR voice service fmin The calculation formula is:

[0177]

[0178] S82: Determine a second buffer amount according to the elements in the actual channel quality feedback indicator matrix and a preset maximum transmit power.

[0179] The terminal adjusts the transmit power when the high buffer amount ΔΨ fg The highest channel quality index Ψ for normal 5GNR voice service using the elements in the matrix T and the terminal fmax The calculation formula is:

[0180]

[0181] In an embodiment of the present invention, the confirmation information is determined by the base station based on the current network capacity and spectrum resources of the high-speed rail network.

[0182] In a specific implementation, after receiving the adjusted transmit power of the terminal, the base station can determine whether the transmit power fed back by the terminal is lower than the required value based on the current network capacity and spectrum resources. If so, the terminal is required to increase the transmit power; otherwise, the terminal is required to reduce the transmit power.

[0183] The required value can be adjusted dynamically, and the adjustment method specifically includes the following steps:

[0184] Set initial required values ​​based on experience and standards, monitor the power feedback information and channel quality feedback information of terminals in the high-speed rail network in real time, evaluate the status of the high-speed rail network in real time, and dynamically update the required values.

[0185] If the current network capacity and spectrum resources are both less than the required values, the degree of deviation can be calculated. If the degree of deviation is greater than the set threshold, the terminal needs to increase the transmission probability. The frequency resources are represented by spectrum utilization. The required values ​​include the current network capacity requirement and spectrum utilization requirement. The calculation formula for the degree of deviation is: In the formula, Pc is the degree of deviation, Dy is the current network capacity requirement, DYy is the current network capacity, α 1 is the network capacity deviation weight factor, Py is the spectrum utilization requirement, PYy is the spectrum utilization, α 2 In this implementation, the base station determines whether the transmit power fed back by the terminal is lower than the required value according to the current network capacity and spectrum resources, and dynamically adjusts the power allocation in the network by requiring the terminal to increase or reduce the transmit power, so as to optimize the utilization of network capacity and spectrum resources.

[0186] By dynamically adjusting the required value, the base station can evaluate the status of the high-speed rail network based on the terminal power feedback information and channel quality feedback information monitored in real time. Based on the evaluation results, the required value is dynamically updated to ensure that the terminal transmission power meets the requirements. This can improve the signal coverage and quality, reduce communication interruptions and weak signals, and improve the quality and reliability of voice services.
