Embodiment
In prior art, when network side sends to the message transmission rate of mobile terminal to exceed the disposal ability of mobile terminal, the data buffer storage that network side sends by mobile terminal is at wireless chain control layer.When in wireless chain control layer, the data of buffer memory exceed largest buffered data volume, data transmission terminal, the total data being buffered in wireless chain control layer is removed by mobile terminal, and network layer sends data to mobile terminal again, and mobile terminal accepts data more again.While waste interface-free resources, impact be also result on transfer of data.
In embodiments of the present invention, when detecting that data volume data cached in wireless chain control layer exceedes the first default threshold value, send the first control command reducing data transmission rate to network side, reduce network side sends speed from data to wireless chain control layer.By reducing the data transmission rate of network side, network side can be effectively avoided to continue to send data with legacy data transmission rate to wireless chain control layer, and the data cached largest buffered value that exceedes caused, the data cached problem be all cleared, therefore effectively can eliminate the waste of interface-free resources, reduce the impact on transfer of data.
For enabling above-mentioned purpose, the feature and advantage of the embodiment of the present invention more become apparent, below in conjunction with accompanying drawing, specific embodiments of the invention are described in detail.
With reference to Fig. 1, give a kind of mobile terminal data transmission control method in the embodiment of the present invention, be described in detail below by way of concrete steps.
Step S101, detects data volume data cached in wireless chain control layer in real time.
In concrete enforcement, when mobile terminal receives the data that network side sends, if when network layer sends to the data rate of mobile terminal to exceed the disposal ability of mobile terminal, can by the data buffer storage that cannot process immediately in wireless chain control layer.Mobile terminal can detect data volume data cached in wireless chain control layer in real time, and when the data volume of buffer memory reaches certain value, performs step S102.
Step S102, when detecting that described data cached data volume exceedes the first default threshold value, sends the first control command reducing data transmission rate to network side.
In concrete enforcement, can arrange the first threshold value according to actual conditions, the first threshold value is less than the largest buffered data volume that wireless chain control layer can be data cached.In embodiments of the present invention, the first threshold value can be 70% ~ 90% of largest buffered data volume.Such as, in an embodiment of the present invention, the first threshold value is 80% of wireless chain control layer largest buffered data volume.And for example, in an alternative embodiment of the invention, the first threshold value is 75% of wireless chain control layer largest buffered data volume.Be understandable that, the first threshold value can also be other values, is not limited in 75% ~ 90% in the embodiment of the present invention, repeats no more herein.
In an embodiment of the present invention, according to step S101, data volume data cached in wireless chain control layer can be detected in real time.When detecting that data volume data cached in wireless chain control layer reaches 80% of wireless chain control layer largest buffered data volume, send the first control command reducing data transmission rate to network side.
In embodiments of the present invention, according to the transmission rate of the data cached processing speed of current mobile terminal process and current network side, the first control command reducing data transmission rate can be determined.In an embodiment of the present invention, the instruction of the first control command to be net control side data transmission rate be data transmission rate minimum value.In actual applications, network side data transmission rate minimum value is send 1 packet each second, and namely the first control command is the instruction that net control side data send window value WINDOWSUFI equals 1.
Be understandable that, network side data send window value WINDOWSUFI in first control command can also be other values, such as, WINDOWSUFI=2 or WINDOWSUFI=5, as long as the data volume meeting the network side transmission received in same time is less than the data volume of mobile terminal process, namely after adjustment, the data transmission rate of network side can not cause data cached continuation in wireless chain control layer to increase.
Step S103, network side, according to described first control command, reduces data transmission rate.
In embodiments of the present invention, after network side receives the first control command of mobile terminal wireless chain control layer transmission, data transmission rate can be adjusted to the data transmission window value set in the first control command, thus can data transmission rate be reduced, avoid data volume data cached in wireless chain control layer to exceed largest buffered data volume.
Such as, in the first control command that network side receives, data transmission window value is WINDOWSUFI=1, then network side adjustment data transmission rate, makes the data transmission rate after adjusting be send 1 packet each second.
As can be seen here, when detecting that data volume data cached in wireless chain control layer exceedes the first default threshold value, sending the first control command reducing data transmission rate to network side, reducing network side sends speed from data to wireless chain control layer.By reducing the data transmission rate of network side, network side can be effectively avoided to continue to send data with legacy data transmission rate to wireless chain control layer, and the data cached largest buffered value that exceedes caused, the data cached problem be all cleared, therefore effectively can eliminate the waste of interface-free resources, reduce the impact on transfer of data.
In actual applications, after reduction network side data transmission rate, because mobile terminal processes the data of buffer memory in wireless chain control layer in real time, and mobile terminal is greater than to the data cached speed processed the speed that network side sends to wireless chain control layer each second in real time, therefore, after reduction network side data transmission rate, data volume data cached in wireless chain control layer reduces gradually.When data volume data cached in wireless chain control layer reduces gradually, in order to ensure the efficiency of transfer of data, the another kind of mobile terminal data transmission control method that the embodiment of the present invention can be adopted to provide.
With reference to Fig. 2, the embodiment of the present invention gives another kind of mobile terminal data transmission control method.Be with the difference of above-described embodiment, after step S101 ~ S103, namely after send the first control command reducing data transmission rate to network side, perform step S104 ~ S105, be specifically described as follows:
Step S104, when detecting that data volume data cached in wireless chain control layer is less than the second default threshold value, sends the second control command improving data rate to network side.
In an embodiment of the present invention, after mobile terminal reduces the first control command of data transmission rate by wireless chain control layer to network side transmission, data volume data cached in wireless chain control layer is detected in real time.When data volume data cached in wireless chain control layer is less than the second default threshold value, send the second control command improving data transmission rate to network side.
In embodiments of the present invention, can arrange the second threshold value according to actual conditions, the second threshold value need be less than the first threshold value in the present invention in an embodiment.In embodiments of the present invention, the second threshold value can be 10% ~ 30% of largest buffered data volume.Such as, in an embodiment of the present invention, the second threshold value is 20% of wireless chain control layer largest buffered data volume.And for example, in an alternative embodiment of the invention, the second threshold value is 15% of wireless chain control layer largest buffered data volume.Second threshold value can also be other values, is not limited in 10% ~ 30% in the embodiment of the present invention, repeats no more herein.
In an embodiment of the present invention, after sending the first control command by wireless chain control layer to network side, detect data volume data cached in wireless chain control layer in real time.When detecting that data volume data cached in wireless chain control layer is less than 20% of wireless chain control layer largest buffered data volume, send the second control command improving data transmission rate to network side.
Step S105, network side, according to the second control command, improves data transmission rate.
In embodiments of the present invention, the second control command can be the data transmission rate that the data transmission rate of net control side reaches the maximum network side that network side can send.In actual applications, network side can be crossed network side data send window value when sending the data transmission rate of maximum network side and equal 4095, and the second control command is now the control command comprising WINDOWSUFI=4095.The implication of WINDOWSUFI=4095 is: if the maximum data transmission rate of current network side is less than send 4095 packets each second, then network side sends data according to maximum data transmission rate.
Such as, the maximum data transmission rate of current network side is send 100 packets each second, and in the second control command that network side receives, when data transmission window value is 4095, then the number of the packet of network side transmission each second is 100.
Be understandable that, net control side data send window value WINDOWSUFI in second control command can also be other values, such as, WINDOWSUFI=4094 or other values, as long as can be adjusted to maximum data transmission rate by the transmission rate of network side.
As can be seen here, after reduction network side data transmission rate, detect data volume data cached in wireless chain control layer in real time, when data cached data volume is less than the second threshold value, improve the data transmission rate of network side, improve the efficiency of transfer of data.
