Data transmission method, offloading point device, user equipment, and system

摘要

An embodiment of the present invention provides a data transmission method, which includes: receiving offloading control signaling sent by a user equipment, where the offloading control signaling carries a cellular network identifier and a wireless local area network WLAN identifier of the user equipment; establishing correspondence between the WLAN identifier of the user equipment and all bearer channels of the user equipment; determining a bearer channel corresponding to all or a part of the user data streams. Embodiments of the present invention further provide a corresponding device and system. Through the technical solutions of the embodiments of the present invention, a transmission rate of a system can be increased.

主权项

1. A data transmission method, comprising:
receiving offloading control signaling sent by a user equipment, wherein the offloading control signaling carries a cellular network identifier and a wireless local area network (WLAN) identifier of the user equipment; according to the cellular network identifier and the WLAN identifier of the user equipment, establishing correspondence between the WLAN identifier of the user equipment and bearer channels of the user equipment; and according to a data offloading manner determined by negotiating with the user equipment and the correspondence, the data offloading manner being used to designate all or a part of user data streams in at least one of a downlink and uplink direction of the user equipment that are transmitted through a WLAN air interface corresponding to the WLAN identifier while maintaining control plane communication through a cellular network of the cellular network identifier, determining a bearer channel corresponding to all or a part of the user data streams.
