Fig. 2 is the another kind of data transmission method schematic flow sheet of the embodiment of the present invention, as shown in Figure 2, comprising:
Step 201: when source node is determined to carry out transfer of data, obtains the disposal ability of the total amount of data of data to be transmitted, the current transmission rate between mobile terminal and IT application server and mobile terminal; The amount that numerical value is less in described current transmission rate and disposal ability is as standard volume.
Wherein, the acquisition methods of described current transmission rate can be: mobile terminal sends packet to IT application server, the delivery time of record data bag; IT application server returns to mobile terminal and receives response; Mobile terminal receives described response, records the time of reception; According to data volume and the described delivery time of described packet with determine described current transmission rate the time of reception.
Or, the process that also process of above-mentioned acquisition current transmission rate can be performed as one-period, each cycle preserves after getting described current transmission rate, like this, when determining in this step to carry out transfer of data, source node can get current transmission rate by the mode of above-mentioned transmission packet, as long as read described current transmission rate from corresponding memory address, thus by periodically obtaining the accuracy that current transmission rate maintains current transmission rate, and, improve the execution efficiency of this step.
Wherein, source node can be IT application server, now, generally sends request of data, so that IT application server issues corresponding data by the IT application of mobile terminal to IT application server.And the request of data that mobile terminal is sent comprises: the current transmission rate between mobile terminal and IT application server and the disposal ability of mobile terminal, as maximum manageable data volume, maximum can the data volume etc. of buffer memory;
