Data transmission method and device

Abstract

The present invention provides a data transmission method and device. The method includes: determining, by a first radio access device, a UE on which traffic offload is required, and sending a traffic offload configuration message to the UE, so that after receiving the traffic offload configuration message, the UE acquires information about an RB on which traffic offload can be performed; receiving a traffic offload configuration completion message sent by the UE, where the traffic offload configuration completion message includes information about a second radio access device associated with the UE; establishing a user plane channel with the second radio access device; transmitting the first data over an air interface of a first radio access technology between the first radio access device and the UE; and transmitting the second data over an air interface of a second radio access technology between the second radio access device and the UE and through the user plane channel. The bandwidth on an air interface can be increased in the embodiments of the present invention.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a data transmission method and equipment. Background technique [0002] Currently, for an evolved packet system (Evolved Packet System, EPS), an air interface adopts a Long Term Evolution (Long Term Evolution, LTE) technology, and is implemented by deploying an evolved base station (evolved NodeB, eNodeB). When user equipment (User Equipment, UE) uses services in the EPS system, the UE performs LTE air interface transmission through the eNodeB deployed in the network. [0003] A wireless local area network (Wireless Local Area Network, WLAN) is a system that uses radio frequency (Radio Frequency, RF) technology for data transmission. As a standard of WLAN, a wireless fidelity (Wireless Fidelity, WIFI) network is a wireless network composed of an access point (Access Point, AP) and a wireless network card. AP, also known as a network bridge, is a bridge between a wire...

AI Technical Summary

Problems solved by technology

[0004] With the increase of bandwidth demand, in order to increase the air interface transmission bandwidth, network operators can deploy more LTE base stations, but this will lead to an increase in investment costs and maintenance costs

If only WIFI technology is used, due to coverage reasons, the service to UE will not be seamlessly switched, which will reduce user experience
