[0050] Compared with the prior art, the beneficial effect of the present invention lies in that, by analyzing the data to be transferred to determine the data type and data loss situation, the accuracy and reliability of the analysis result are improved to reduce business interruption caused by data loss, and the corresponding transmission channel is determined according to the data type, the signal transmission path and method are optimized, and the transmission efficiency is improved. The initial transmission mode is adjusted according to the data loss situation to determine the target transmission mode. By adjusting the transmission mode, it is ensured that data can be reliably transmitted even in poor channel conditions, reducing the risk of data damage or loss, recording the transmission time period of each sub-data, and analyzing the number of sub-data and the corresponding data volume in any transmission time period, helping to identify the time period with tight bandwidth or low utilization, and helping to more reasonably allocate network resources in future transmission cycles, increase transmission channels during peak demand periods, thereby improving the overall utilization of network resources.

[0051] In particular, by classifying data for targeted analysis, the accuracy and reliability of the analysis results can be improved, and loss analysis can be performed on each data type to determine the data loss situation and reduce business interruptions caused by data loss.

[0052] In particular, by conducting a detailed analysis of the loss of voice, file packages, and video, different security measures are implemented for different types of data to more effectively protect against data damage.

[0053] In particular, by classifying the voice, file package and video and transmitting them in different ways, the transmission mapping mode of each signal is determined to optimize the transmission path and method of the signal, thereby improving the transmission efficiency and reducing the waste of network transmission resources.

[0054] In particular, by analyzing the attenuation of the lost speech and increasing the transmission power, the attenuation area encountered by the signal during transmission is accurately identified, and the transmission power is increased accordingly to ensure that the signal maintains sufficient strength when reaching the receiving end, thereby reducing the degradation or loss of speech quality due to signal attenuation. The initial transmission mode is adjusted according to the setting of the filter to suppress noise. By suppressing background noise, the receiving end can hear the speech content more clearly and reduce speech ambiguity or misunderstanding caused by noise interference.

[0055] In particular, by analyzing the signal of the transferred data, the initial voice power is determined, and based on the difference between the initial voice power and the final voice power, the required increase in transmission power is accurately calculated. By adjusting the transmission power, the risk of communication interruption is reduced and the reliability of communication is improved.

[0056] In particular, by analyzing the packet loss rate of the file packets and adopting the TCP transmission protocol to ensure the correct transmission of the data packets, when there are network fluctuations or unstable factors, TCP can automatically retransmit the lost data packets, thereby significantly reducing the packet loss rate, and adding repeaters according to the areas where the video quality is reduced, thereby expanding the signal coverage range and ensuring that the video signal can reach the target terminal. The pointing angle of the antenna is adjusted in the bandwidth-restricted area. The precisely pointed antenna reduces signal interference to non-target terminals, and also reduces interference of other signals to the antenna, thereby expanding the bandwidth and increasing the signal flow rate.

[0057] In particular, by aligning the antenna's maximum radiation direction toward the target terminal, the signal strength received in that direction is significantly improved. This is especially important for target terminals located in bandwidth-restricted areas or areas with weak signals. It ensures that signals of sufficient strength are received, thereby improving the stability and reliability of data transmission.

[0058] In particular, the target transmission period is determined by counting the total number of sub-data in any transmission period, and the peak period of data transmission is judged according to the total number of sub-data, so that measures can be taken to reduce congestion in the period, thereby reducing the load of the target transmission period and improving the overall transmission efficiency.
