[0039] The method embodiments provided in the embodiments of the present invention can be executed in a computer terminal, a computer terminal or a similar computing device. Taking running on a computer terminal as an example, Figure 1 FIG. 1 is a hardware structure block diagram of a computer terminal of a signal transmission control method according to an embodiment of the present invention. Figure 1 As shown, the computer terminal may include one or more ( Figure 1 Only one is shown in the figure) processor 102 (processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data.

It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above-mentioned computer terminal. Figure 1 More or fewer components as shown, or with Figure 1 Equivalent functions or comparisons shown Figure 1 A different configuration with more features is shown.

[0040] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the signal transmission control method in the embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method.

[0042] In this embodiment, a signal transmission control method is provided, which is applied to a monitoring device, wherein the monitoring device is used to connect to a transmission device to be monitored, and the transmission device is used to transmit a signal according to a gain parameter configured by the monitoring device. Figure 2 is a flow chart of a signal transmission control method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0043] Step S202, extracting the initial power of the initial signal currently transmitted by the transmission device;

[0044] Step S204, detecting whether the initial power of the initial signal is greater than or equal to a power threshold, and obtaining a detection result;

[0045] Step S206, when the detection result indicates that the consecutive target times of the initial power are greater than or equal to the power threshold, detecting the transmission type of the initial signal;

[0046] Step S208, in a case where the transmission type is used to indicate that the initial signal is a signal currently output by the transmission device, the initial gain parameter of the transmission device corresponding to the initial signal is adjusted to a target gain parameter according to a power difference between the initial power and the power threshold, and exception information is generated, wherein the transmission device is used to output a target signal according to the target gain parameter, the target signal is the next signal output by the transmission device after the initial signal, the power of the target signal is less than the power threshold, and the exception information is used to indicate that the initial power is abnormal.

[0047] Through the above steps, the monitoring device can detect in real time whether the signal power of the signal currently transmitted by the transmission device exceeds the preset power threshold. If the signal power exceeds the power threshold for multiple times in a row, it can indicate that the power of the signal transmitted by the transmission device is abnormal. In this case, the monitoring device can automatically adjust the gain parameter required for the output signal of the transmission device so that the power of the signal output by the transmission device next time is within the normal range, avoiding signal errors or signal interference caused by the power abnormality of the signal output by the transmission device. The above technical solution solves the problem of low signal transmission quality in the related technology and achieves the technical effect of improving the signal transmission quality.

[0048] In the technical solution provided in the above step S202, the transmission device may be but is not limited to being used to transmit signals according to the gain parameters configured by the monitoring device, and the transmission device may be but is not limited to including OFDM deployed in the ORU device and inverse OFDM deployed in the ORU device, etc.

[0049] Optionally, in this embodiment, extracting the power of the signal currently transmitted by the transmission device may include but is not limited to extracting the power of the signal currently output by the transmission device or the power of the signal currently input to the transmission device. For example, it may include but is not limited to extracting the power of the current OFDM received signal, or the power of the current OFDM output signal, or extracting the power of the current inverse OFDM received signal or extracting the power of the current inverse OFDM output signal.

[0050] In an exemplary embodiment, it is possible but not limited to that before extracting the initial power of the initial signal currently transmitted by the transmission device: the power threshold is set by the following formula:

[0051]

[0052] Wherein, IQ_power_level is the power threshold, RB is the number of resource blocks of the transmission device, and RB is determined according to the signal bandwidth of the transmission device and the signal type of the transmission device.

[0053] Optionally, in this embodiment, the power threshold corresponding to the signal input to the transmission device and the power threshold corresponding to the signal output from the transmission device may be the same or different but is not limited to being the same.

[0054] Optionally, in this embodiment, for the frequency domain signal power threshold setting, the frequency domain signal may be, but is not limited to, in symbols. Currently, the ODU uses a total symbol power of 0 dBFS (Decibels Full Scale) as the standard. The average power level of a single IQ (In-phase and Quadrature) may be calculated based on, but is not limited to, the signal bandwidth and signal type (for example, LTE or NR). The calculation formula is shown in formula (1):

[0055]

[0056] Among them, IQ_power_level is the frequency domain power threshold (equivalent to the power threshold), RB (Resource Block) is the number of resource blocks of the transmission device, and the actual frequency domain power threshold should be set to IQ_power_level.

[0057] It should be noted that different devices have different definitions of full power in the digital signal processing part. For ORU devices, the maximum power of the time domain signal is -14dBFS, and the time domain signal power threshold can be set to -14dBFS but is not limited to.

[0058] In an exemplary embodiment, a first signal collector is deployed in the monitoring device, and the transmission device includes a first transmission device. The first signal collector is connected to the first transmission device and can extract the initial power of the initial signal currently transmitted by the transmission device in the following manner but is not limited to: when a first frequency domain signal is input into the first transmission device, the first signal description information of the first frequency domain signal is collected by the first signal collector, wherein the initial signal includes the first frequency domain signal; and the first signal power of the first frequency domain signal is filtered from the first signal description information, wherein the initial power includes the first signal power.

[0059] Optionally, in this embodiment, the first transmission device may be, but is not limited to, used to convert a received frequency domain signal into a time domain signal. For example, the first transmission device may be, but is not limited to, include OFDM deployed in an ORU device.

[0060] Optionally, in this embodiment, the first signal collector can be used but is not limited to collecting the power of frequency domain signals, for example, collecting the frequency domain signal of the input OFDM in the downlink, or monitoring the frequency domain signal of the inverse OFDM output in the uplink. The downlink can be but is not limited to including the link from ODU to ORU and the link between ORU and terminal device.

[0061] Optionally, in this embodiment, the frequency domain signal may include but is not limited to a signal in the frequency domain. The frequency domain is a coordinate system used to describe the characteristics of the sound signal in terms of frequency. After converting the sound signal from the time domain to the frequency domain, an amplitude spectrum is obtained, wherein the horizontal axis of the amplitude spectrum is the frequency point and the vertical axis is the spectrum amplitude at the frequency point. The frequency point may correspond to but is not limited to a discrete frequency value in the spectrum analysis, and may be used to indicate the existence and intensity of a specific frequency component in the frequency domain signal. The spectrum amplitude may be used to indicate but is not limited to indicate the energy or power of the signal at different frequency points. The height of the spectrum amplitude may indicate but is not limited to the magnitude of the energy or power at different frequency points. For example, the higher the spectrum amplitude at the frequency point, the higher the energy or power at the frequency point. As an optional example, the signal in the frequency domain may be converted to the time domain by, but is not limited to, inverse fast Fourier transform (or other inverse transforms, which are not limited in this application), to obtain a time domain signal.

[0062] Optionally, in this embodiment, the first frequency domain signal may include, but is not limited to, a frequency domain signal of an input OFDM in a downlink.

[0063] Optionally, in this embodiment, the signal description information of the frequency domain signal may include but is not limited to initial state information of the frequency domain signal, for example, spectrum distribution of the signal in the frequency domain, power of the signal, and the like.

[0064] Optionally, in this embodiment, the signal power of the frequency domain signal can be filtered from the signal description information in the following manners, but not limited to: directly filtering out the signal power of the frequency domain signal from the signal description information; or, after parsing the signal description information, filtering out the signal power of the frequency domain signal therefrom. For example, in the signal description information, parameter 1 can be recorded in field 1, but not limited to, and there is a one-to-one correspondence between the value of parameter 1 and the value of the power of the signal. For example, the value of parameter 1 is 3, corresponding to a current signal power of 30dBFS.

[0065] Through the embodiments of the present application, through the correspondence between predefined parameters and power, fewer bits can be used to represent signal power, which not only saves the space required to store signal description information, but also enables rapid acquisition of signal power information, greatly improving the efficiency of monitoring signal power.

[0066] In an exemplary embodiment, a first signal collector is deployed in the monitoring device, and the transmission device includes a second transmission device. The first signal collector is connected to the second transmission device and can extract the initial power of the initial signal currently transmitted by the transmission device in the following manner, but is not limited to: when the second transmission device converts the received time domain signal into a second frequency domain signal and outputs the second frequency domain signal, the second signal description information of the second frequency domain signal is collected by the first signal collector, wherein the initial signal includes the second frequency domain signal; and the second signal power of the second frequency domain signal is filtered from the second signal description information, wherein the initial power includes the second signal power.

[0067] Optionally, in this embodiment, the second transmission device may be, but is not limited to, used to convert the received time domain signal into a frequency domain signal, and the second transmission device may be, but is not limited to, include an inverse OFDM deployed in the ORU device.

[0068] Optionally, in this embodiment, the second frequency domain signal may include but is not limited to a frequency domain signal of an inverse OFDM output in an uplink, and the uplink may include but is not limited to a link from a terminal device to an ORU and between an ORU and an ODU.

[0069] It should be noted that the method of filtering the second signal power from the second signal description information is the same as the method of filtering the first signal power from the first signal description information, and this application will not go into details here.

[0070] In an exemplary embodiment, a second signal collector is deployed in the monitoring device, the transmission device includes a first transmission device, the second signal collector is connected to the first transmission device, and the second signal collector is connected to the transmission device. The initial power of the initial signal currently transmitted by the transmission device can be extracted in the following manner but is not limited to: when the first transmission device converts the input frequency domain signal into a first time domain signal and outputs the first time domain signal, the third signal description information of the first time domain signal is collected by the second signal collector, wherein the initial signal includes the first time domain signal; and the third signal power of the first time domain signal is filtered from the third signal description information, wherein the initial power includes the third signal power.

[0071] Optionally, in this embodiment, the second signal collector can be used, but is not limited to, to monitor time domain signals, for example, to monitor the time domain signal of OFDM output in the downlink; or, to monitor the time domain signal of input inverse OFDM in the uplink.

[0072] Optionally, in this embodiment, the time domain signal may include but is not limited to a signal in the time domain, where the horizontal axis is time and the vertical axis is the amplitude of the sound signal. The transmission device may convert the signal in the time domain into the frequency domain through but is not limited to fast Fourier transform (or other transformations, which are not limited in this application) to obtain a frequency domain signal.

[0073] It should be noted that the method of filtering the third signal power from the third signal description information is the same as the method of filtering the first signal power from the first signal description information, and this application will not go into details here.

[0074] In an exemplary embodiment, a second signal collector is deployed in the monitoring device, the transmission device includes a second transmission device, and the second signal collector is connected to the second transmission device. The initial power of the initial signal currently transmitted by the transmission device can be extracted in the following manner but is not limited to: when the second time domain signal is input into the second transmission device, the fourth signal description information of the second time domain signal is collected by the second signal collector, wherein the initial signal includes the second time domain signal; and the fourth signal power of the second time domain signal is filtered out from the fourth signal description information, wherein the initial power includes the fourth signal power.

[0075] Optionally, in this embodiment, the method of filtering the fourth signal power from the fourth signal description information is the same as the method of filtering the first signal power from the first signal description information, and this application will not go into details here.

[0076] Optionally, in this embodiment, it is possible but not limited to monitoring in parallel whether the power of the signal input to the transmission device and the power of the signal output by the transmission device are abnormal. For example, it is possible but not limited to detecting in parallel whether the first signal power, the second signal power, the third signal power and the fourth signal power are abnormal.

[0077] Figure 3 is an optional signal transmission system architecture diagram according to an embodiment of the present invention, such as Figure 3 As shown in the figure, the monitoring system (equivalent to the monitoring equipment) is the core part of the signal transmission system architecture, including the frequency domain signal monitor (equivalent to the first signal collector), the gain corrector and the time domain signal monitor (equivalent to the second signal collector). The monitoring system is used for the Low_Phy part of the ORU. For the frequency domain signals and time domain signals at both ends of the Low_Phy, the entire monitoring system monitors the uplink and downlink time and frequency domain digital signals in real time. If there is a continuous power overflow, it will be corrected immediately and the abnormal information will be reported.

[0078] The downlink starts with the ECPRI (Enhanced Common Public Radio Interface) interface receiving a frequency domain signal from the ODU. The frequency domain signal is modulated by OFDM and converted from the frequency domain to the time domain to obtain a time domain signal, which is sent to the user's terminal device or antenna, etc. The uplink starts with the time domain signal from the user's terminal device or antenna, etc. The time domain signal is inversely modulated by OFDM and converted from the time domain back to the frequency domain to form a frequency domain signal, which is sent to the ODU through the ECPRI interface.

[0079] The frequency domain monitor and the time domain monitor can monitor the signals output by the transmission device (e.g., the time domain signal output by OFDM and the frequency domain signal output by inverse OFDM) and the signals input by the transmission device (e.g., the frequency domain signal input by OFDM and the time domain signal input by inverse OFDM) in real time and in parallel, but are not limited to, to detect whether the signal power exceeds a predetermined power threshold. If the output signal power exceeds the power threshold, the gain corrector will adjust the gain parameter of the link corresponding to the output signal according to the difference between the actual power and the threshold, to ensure that the power of the next signal output by the transmission device remains within a safe range, and will report abnormal information at the same time; if the signal power input to the transmission device exceeds the power threshold, the monitoring system will report abnormal information.

[0080] Optionally, in this embodiment, the frequency domain signal monitor may be used, but is not limited to, to monitor the frequency domain signal of OFDM input in the downlink, or the frequency domain signal of the inverse OFDM output in the uplink.

[0081] Optionally, in this embodiment, the time domain monitor may be, but is not limited to, used to monitor the time domain signal of OFDM output in the downlink, or the time domain signal of inverse OFDM input in the uplink.

[0082] Optionally, in this embodiment, the gain corrector may be used, but not limited to, to correct the power of a time domain signal output by OFDM in a downlink, or to correct the power of a frequency domain signal output by inverse OFDM in an uplink.

[0083] In the technical solution provided in the above step S204, the power threshold may include but is not limited to a power threshold of a time domain signal and a power threshold of a frequency domain signal. The power threshold of the time domain signal and the power threshold of the frequency domain signal may be but are not limited to being the same or different.

[0084] Optionally, in this embodiment, the frequency domain signal power detection period can be but not limited to a symbol as a unit, that is, the number of RBs in a symbol. The time domain signal power detection can be but not limited to an IQ number as a unit. To facilitate FPGA (Field-Programmable Gate Array) power calculation, the IQ number can be but not limited to 2. n .

[0085] In the technical solution provided in the above step S206, when the detection result is used to indicate that the initial power is not continuously the target number of times (for example, 3 times or 5 times, etc., which is not limited in the present application) is greater than or equal to the power threshold, it can be indicated that the power of the signal currently output by the transmission device and the power of the signal currently input to the transmission device The abnormality may be caused only by signal fluctuations, rather than an abnormality in the gain parameters of the transmission device. In this case, it is possible but not limited to maintaining the current gain parameters of the transmission device.

[0086] Optionally, in this embodiment, taking the continuous target number of times including but not limited to 3 times as an example, when the power of the signal currently transmitted by the transmission device is greater than or equal to the power threshold for 3 consecutive times, the signal may be but not limited to the same output signal that has been abnormal for 3 consecutive times. In this case, it is only necessary to adjust the link gain parameter corresponding to the output signal. For example, if the output signal (time domain signal) of the downlink has been abnormal for 3 consecutive times, the gain parameter of the downlink is adjusted. Alternatively, the power of the signal is greater than or equal to the power threshold for 3 consecutive times. The signal may be but not limited to different output signals (for example, the output signal of the uplink (for example, the frequency domain signal) and the output signal (time domain signal) of the downlink) have been abnormal for 3 consecutive times. In this case, it is necessary to adjust the corresponding uplink and downlink gain parameters.

[0087] Figure 4is an optional time-frequency domain signal monitoring flow chart according to an embodiment of the present invention, such as Figure 4 As shown, signal monitoring may include but is not limited to frequency domain signal monitoring and time domain signal monitoring, and may include but is not limited to taking the continuous target number of 3 times as an example. The monitoring system detects the actual power of the time domain signal and the actual power of the frequency domain signal in real time during signal transmission, and compares them with the power threshold. When the actual power is less than the power threshold, it is determined that the power of the signal currently transmitted by the transmission device is normal; when the actual power is greater than or equal to the power threshold, it is determined that the power of the signal currently transmitted by the transmission device is abnormal. The number of consecutive abnormalities is counted, and when the actual power is detected to be greater than or equal to the power threshold for three consecutive times, an abnormality report is made.

[0088] Optionally, in this embodiment, the transmission type of the signal may include but is not limited to a signal input to a transmission device or a signal output by a transmission device.

[0089] In the technical solution provided in the above step S208, when the transmission type is used to indicate that the initial signal is a signal currently input to the transmission device, abnormal information is generated, wherein the abnormal information is used to indicate that an abnormality occurs in the initial power.

[0090] Optionally, in this embodiment, the initial gain parameters may include but are not limited to uplink gain parameters and downlink gain parameters. For example, when the power of the uplink frequency domain signal exceeds the power threshold, the initial gain parameters may include but are not limited to uplink gain parameters; when the power of the downlink time domain signal exceeds the power threshold, the initial gain parameters may include but are not limited to downlink gain parameters.

[0091] Figure 5 is an optional time-frequency domain signal abnormality processing flow chart according to an embodiment of the present invention, such as Figure 5 As shown, the gain parameters corresponding to the power of the signal output by the transmission device can be adjusted and reported, but are not limited to. When the power of the signal input to the transmission device is abnormal, only reporting is performed. For example, since the frequency domain signal in the downlink and the time domain signal in the uplink are both input signals for low phy, the power of the original signal cannot be adjusted, so only reporting is performed when an abnormality occurs. The frequency domain signal in the uplink and the time domain signal in the downlink are output signals of low phy, and gain correction and abnormality reporting can be performed when an abnormality occurs. Power correction is to calculate the calibration value by the power overflow value and UL Gain or DL ​​Gain.

[0092] In an exemplary embodiment, a gain corrector is deployed in the monitoring device, and the gain corrector is connected to the transmission device. The initial gain parameter of the transmission device corresponding to the initial signal can be adjusted to a target gain parameter according to the power difference between the initial power and the power threshold in the following manner, but is not limited to: determining a gain parameter adjustment amount according to the power difference, and determining the target gain parameter as a parameter obtained by subtracting the gain parameter adjustment amount from the initial gain parameter; and adjusting the initial gain parameter to the target gain parameter through the gain corrector.

[0093] Optionally, in this embodiment, the units of the power and gain parameters may be, but are not limited to, the same. For example, the units of the power and gain parameters may be, but are not limited to, both being dBFS. The power difference value and the gain parameter adjustment amount may be, but are not limited to, the same. For example, the real-time power detection result is 15dBFS, and the power threshold is set to 10dBFS, which means that the signal power exceeds the threshold by 5dBFS. In this case, the gain corrector uses the calculated power difference value (such as 5dBFS) directly as the gain parameter adjustment amount, that is, the gain parameter is reduced by the same amount (5dBFS).

[0094] As an optional example, the target gain parameter can be calculated by subtracting the adjustment amount from the initial gain parameter of the transmission device according to the gain parameter adjustment amount, but is not limited to. Assuming that the initial gain parameter is N dBFS and the power difference is MdBFS, the target gain parameter is (NM)dBFS, where N is an integer and M is an integer.

[0095] Through the embodiments of the present application, according to the real-time power and power threshold of the signal currently transmitted by the transmission device, a rapid response to signal power changes is achieved, and the gain parameters are dynamically adjusted, thereby improving the adjustment efficiency of the gain parameters.

[0096] In an exemplary embodiment, the initial gain parameter can be adjusted to the target gain parameter through the gain corrector in the following manner, but is not limited to: generating a target adjustment instruction, wherein the target adjustment instruction is used to request that the gain parameter of the transmission device be adjusted from the initial gain parameter to the target gain parameter; transmitting the target adjustment instruction to the transmission device through the gain corrector, wherein the transmission device is used to execute the target adjustment instruction.

[0097] Optionally, in this embodiment, the target gain parameter to which the transmission device needs to be adjusted and the link (for example, the identifier of the uplink) to which the gain parameter needs to be adjusted may be carried in the target adjustment instruction but is not limited to it.

[0098] Figure 6 is a schematic diagram of an optional monitoring process according to an embodiment of the present invention, such as Figure 6 As shown in the figure, the entire monitoring system includes system initialization, signal monitoring, abnormal reporting, and gain correction. Even if it is currently in the signal monitoring state, as long as the device is powered on or the carrier configuration changes, the system initialization will be triggered. After the system initialization is completed, it will enter the signal monitoring state. When the signal power continues to overflow, it will report an abnormality and perform gain correction.

[0099] For system initialization: In actual applications, ODU mainly configures and sends ORU through M-Plane. System initialization mainly obtains relevant information configured by M-plane: DL Gain, UL Gain, signal bandwidth, signal type (LTE (Long Term Evolution) / NR (New Radio)).

[0100] At present, the configuration of ORU is configured through M-Plane first. For the ORAN system, customers are more concerned about the final RF (Radio Frequency) output of RU, and will not check the digital signal power in digital signal processing. In this process, it is impossible to check whether the digital signal power is normal. Through the above embodiments, a method for preventing overflow of ORU digital signals is proposed. When the digital signal power in the time-frequency domain of the ORU device is abnormal, the time-frequency domain signal power is automatically corrected to prevent the overflow of the digital signal in the time-frequency domain and improve the communication quality.

[0101] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present invention is essentially or the part that contributes to the prior art can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, a magnetic disk, or an optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, a computer, a server, or a network device, etc.) to execute the methods of various embodiments of the present invention.

[0106] The processing module 708 is used to adjust the initial gain parameter of the transmission device corresponding to the initial signal to the target gain parameter according to the power difference between the initial power and the power threshold when the transmission type is used to indicate that the initial signal is the signal currently output by the transmission device, and generate exception information, wherein the transmission device is used to output a target signal according to the target gain parameter, the target signal is the next signal output by the transmission device after the initial signal, the power of the target signal is less than the power threshold, and the exception information is used to indicate that the initial power is abnormal.

[0107] Through the above device, the monitoring device can detect in real time whether the signal power of the signal currently transmitted by the transmission device exceeds the preset power threshold. If the signal power exceeds the power threshold for multiple times in a row, it can indicate that the power of the signal transmitted by the transmission device is abnormal. In this case, the monitoring device can automatically adjust the gain parameter required for the output signal of the transmission device so that the power of the signal output by the transmission device next time is within the normal range, avoiding signal errors or signal interference caused by the power abnormality of the signal output by the transmission device.
