Embodiments of the present invention provide a core network device, an access network device, and a data offloading method and system, and relate to the field of mobile communications. In the system, the access network device receives an offloading inclination indication of service data from the core network device; the access network device allocates, according to the offloading inclination indication, a transmission resource used for transmitting the service data; and the access network device transmits the service data by using the allocated transmission resource. In the present invention, a problem is resolved that QoS in a transmission process cannot be ensured when data is offloaded by using a first resource such as an unlicensed spectrum, a transmission resource provided by a WLAN, or a transmission resource provided by a secondary eNodeB, and the QoS in the transmission process can be ensured even if the data is offloaded by using the first resource such as the unlicensed spectrum, the transmission resource provided by the WLAN, or the transmission resource provided by the secondary eNodeB. |
