  • Publication number: 20140198657
    Abstract: Embodiments of the present invention provide a method, a device, and a base station for transmitting data. The method includes: receiving, by a base station, data sent by a core network, where the data is data that needs to be sent to a terminal and the terminal is a terminal that has separately established a connection to the base station and a WiFi access point; selecting, by the base station, one of the base station and the WiFi access point according to a load of the base transceiver station and a load of the WiFi access point; sending the data to the terminal by using the selected base station or WiFi access point. By using the technical solutions according to the embodiments of the present invention, the loads of two networks is balanced and resources of the two networks are effectively used.
