The invention discloses a data transmission method and device, relates to the technical field of communication, and can solve the problem of low data transmission performance. The method comprises thefollowing steps: receiving to-be-transmitted data sent by core network equipment; determining a receiving rate and a sending rate of the to-be-transmitted data; according to the receiving rate and the sending rate, the link quality of a first communication link is determined, and the first communication link is a link between the first network device and the terminal; and if the link quality of the first communication link is less than the preset transmission quality, shunting the to-be-transmitted data to the second network device. In the communication system, the data is reasonably distributed to the communication link according to the receiving rate and the sending rate of the to-be-transmitted data, so that the data transmission performance is improved.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method and device. Background technique [0002] With the continuous development and maturity of mobile Internet services, higher and higher requirements are placed on the transmission rate and transmission delay of wireless communication. In order to achieve a higher transmission rate and lower transmission delay, a dual connectivity system is introduced in the wireless communication standard. [0003] In a dual connectivity system, a terminal can establish communication connections with two base stations at the same time, and transmit data through the communication link with each base station. In the prior art, the data delivered by the core network equipment will be allocated to two communication links according to a preset ratio, and transmitted through the two communication links. If the allocation ratio is inappropriate, it will cause da...
