Abstract

Embodiments of the present invention provide a data transmission method and device, in which a base station sends request information, an identifier of a wireless local area network access point WLAN AP, and a first IP address of the base station to a user equipment, and the request information is used for requesting the user equipment to perform multi-stream aggregation data transmission with the base station via the WLAN AP; the base station receiving the confirmation information sent by the user equipment and the second IP address allocated by the WLAN AP to the user equipment , the confirmation information is used to confirm that the user equipment performs multi-stream aggregation data transmission with the base station via the WLAN AP; the base station performs multi-stream aggregation with the user equipment via the WLAN AP through the IP tunnel For aggregated data transmission, the IP tunnel is determined by the first IP address and the second IP address. This embodiment ensures service continuity during the offloading process.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular, to a data transmission method and device. Background technique [0002] With the rapid development of smart phones, more and more mobile communication terminals are integrated with wireless local area network (Wireless Local Area Network, WLAN for short) communication modules. On the other hand, as people's demand for mobile broadband continues to increase, existing (eg, wireless cellular) communication systems are under increasing pressure from data traffic. [0003] The wireless cellular network has the advantages of wide coverage and high-speed mobile support, but also has the disadvantages of low data rate, high price, and high transmission power. It is more suitable for scenarios such as high-speed sports and large-scale outdoor activities. WLAN, on the other hand, has the advantages of high data rate, low price, low transmission power, etc., and has a s...
