SYSTEM AND METHOD FOR DATA TRAFFIC OFFLOADING

摘要

A method for data traffic offloading to an alternative radio access network among a plurality of available alternative radio access networks for use by a client device connected to a network through a radio access network is provided. The client device has a plurality of types of data traffics. The method comprises registering the client device to a traffic manager residing at the network end, storing in the traffic manager the radio access network performance parameters as expected by each data traffic in the client device. It is then determined whether the expected network performance parameters arc violated, and when the expected network performance parameters are violated, the traffic manager instructing the client device to identify available alternative radio networks, and upon identification, the traffic manager deciding on behalf of the client device which specific data traffic type suitable to offload to the identified available alternative radio networks. A system for such data traffic offloading is also provided herein.
