Abstract

The present invention provides a data transmission method and apparatus based on networks of multiple communications standards. According to the method of the present invention, an air interface state of a first communications standard network and an air interface state of a second communications standard network are detected, a data packet sending rate suitable for the air interface status of the first communications standard network and a data packet sending rate suitable for the air interface state of the second communications standard network are determined, and a data packet is allocated to the first communications standard network and the second communications standard network according to the determined data packet sending rates, so that the data packet may be simultaneously delivered to a user by using the networks of the two communications standards together.
