Data transmission method and apparatus based on networks of multiple communications standards

A data transmission apparatus comprising:

• a processor;
• and
• a computer-readable storage medium storing a program to be executed by the processor, the program comprising instructions for configuring the processor to:
• detect an air interface status parameter of a first communications standard network and an air interface status parameter of a second communications standard network,
• according to the detecting result, decrease a data packet sending rate of the first or second communications standard network when the corresponding air interface status parameter is less than a preset threshold,
• increase the data packet sending rate of the first or second communications standard network when the first or second communications standard network has a decreased data packet sending rate and the air interface status parameter of the first or second communications standard network is not less than the preset threshold, and
• allocate, according to the data packet sending rate of the first communications standard network and the data packet sending rate of the second communications standard network, a first portion of data packets to the first communications standard network and a second portion of data packets to the second communications standard network for sending,
• wherein to increase the data packet sending rate, the processor is configured to:
• detect the air interface status parameter of the communications standard network with the decreased data packet sending rate;
• and
• in response to detecting that the air interface status parameter of the communications standard network with the decreased data packet sending rate is not less than the preset threshold, increase the data packet sending rate of the communications standard network to a rate used before the decreased data packet sending rate.
