Example 2
The present embodiment adds a scheme for adaptively adjusting the size of the fragmented data packet in real time according to the channel condition on the basis of the foregoing embodiments.
Referring to fig. 2, fig. 2 is a schematic diagram illustrating the data slice adaptive adjustment according to this embodiment.
In the process of starting data fragment transmission of a first data block between terminal devices, the current channel state is set to be better in channel condition, and transmission is carried out according to the maximum transmission value of a fragment data packet. If the data fragment transmission is successful, the size of the transmission fragment packet is set as the current transmission value, and the successful transmission times are recorded.
In the data fragment transmission process, if the current channel condition deteriorates and causes the sending end to receive a data transmission failure command or receives no data transmission response command within time and causes transmission failure for 1 time, firstly, the successful transmission times are set to be 0, the current channel condition is adjusted to be the current burst error code, the data fragment is sent again, and if the retransmission is successful, the data fragment is sent continuously according to the current fragment size; if the retransmission still fails, the current channel condition is adjusted to be that continuous error codes exist currently, the residual data of the data block is re-fragmented, the size of the data fragment is half of the size of the original data fragment, so that the transmission success rate is improved, and the size of the current data fragment packet and the successful transmission times are recorded. If the data transmission is successful after the data fragmentation is reduced, recording the successful transmission times, updating the size of the current fragmented data packet, and continuing the transmission of the subsequent data fragmentation. And if the retransmission transmission fails, re-fragmenting the residual data of the data block, and sending the residual data of the data block after the size of the data fragment is half of that of the current data fragment. And setting a maximum retransmission time in data retransmission, and if the data retransmission time is equal to the maximum retransmission time, terminating the data.
Before the next data block is transmitted, whether the number of times of continuous transmission success of the current data fragment is larger than a set fragment transmission size adjustment threshold value or not is judged, the size of the current fragment data packet is smaller than the maximum transmission value, if the two judgment conditions are met, the current channel condition is considered to be recovered to a better state, and the size of the fragment data packet is doubled, so that the transmission efficiency is improved.
The scheme for realizing safe and reliable data auto-negotiation transmission between terminal devices based on the encrypted voice channel can adaptively adjust the size of the fragmented data packet in real time according to the current signaling condition, set the appropriate maximum value and minimum value of the fragmented data packet transmission according to the actual condition, and after the fragmented data packet is equal to the maximum value or the minimum value of the fragmented data packet transmission, the size of the fragmented data packet is not adjusted upwards or downwards any more, so that the transmission success rate and the transmission efficiency are improved.

After the transmission of the data block 3 is completed, the data block 2 is transmitted, before the transmission, it is first judged whether the successful times of the data transmission at this time is greater than a certain successful transmission adjustment threshold value, at this time, the successful transmission times is 6, and is less than a size adjustment threshold value of a fragmented data packet 8, the data block 2 is still fragmented into 8 data fragments of 0, 1, 8230according to the size of the data fragment, and 7, the total number of the data fragments is 8.
After the transmission of the data block 2 is completed, the data block 1 is transmitted, before the transmission, it is first judged whether the number of successful data transmissions is greater than a predetermined successful transmission adjustment threshold value, at this time, the number of successful data transmissions is 14, which is greater than the size adjustment threshold value 8 of the fragmented data packet, the size of the data fragment of the data block 1 is increased to 1 time of the original size, that is, 1024 bytes, and the transmission is divided into 4 data fragments of 0, 1, 2, and 3.
And when the phone B successfully receives the 0 th data fragment of the received data block 0, the data transmission is judged to be finished, the phone B sends an on-hook signaling to the phone A, and the data transmission is finished.
According to the embodiment, the scheme can realize safe and reliable auto-negotiation transmission of data between the devices based on the encrypted voice channel established during the call between the terminal devices, and solves the potential safety hazard of data transmission between the devices. Meanwhile, aiming at the problem that the size of the transmission data fragment cannot be adaptively adjusted according to the channel condition so as to improve the transmission success rate and the transmission efficiency, the data transmission scheme provided by the invention can adaptively adjust the size of the transmission data fragment according to the channel condition, and has a packet error and packet loss retransmission mechanism, so that the success rate and the transmission efficiency of data transmission are improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
