SYSTEM, DEVICE FOR CONVERGENCE TRANSMISSION AND METHOD FOR DATA DISTRIBUTION CONVERGENCE

摘要

A convergent transmission system includes a data offloading and converging node, a cellular access point, and a wireless local area network (WLAN) access point. The data offloading and converging node is configured to: negotiate with a user equipment (UE) to determine a data offloading policy; according to the data offloading policy determined by negotiating with the UE, use a WLAN radio bearer to transmit a part of user data, where the WLAN radio bearer is a result of configuring a part of radio bearers of a cellular system as WLAN radio links; and use a remaining radio bearer of the cellular system to transmit a remaining part of the user data, where the radio bearers are a radio part of bearer channels of the cellular system, and the bearer channels of the cellular system are created through control plane signaling of the cellular system; the WLAN access point is configured to work with the UE and the data offloading and converging node to transmit the part of the user data; and the cellular access point is configured to work with the UE and the data offloading and converging node to transmit the remaining part of the user data.
