  • Method, device and system for offloading network traffic
    Patent number: 9066256
    Abstract: A method, a device, and a system for offloading network traffic are provided, which are applied in the field of mobile communications. An offloading device located before a Serving General Packet Radio Service Support Node (SGSN) receives a data stream of a user sent by a base station, obtains an offloading policy of the user from the offloading device and/or obtains the offloading policy of the user from a policy server, and forwards the data stream according to the offloading policy. Accordingly, the offloading device can obtain the corresponding offloading policy according to the data stream sent by a forwarding plane, send a data stream of low value, low real-time performance requirement, or low priority to the Internet or another specific networks, and send a data stream of high value, high real-time performance requirement, or high priority to high-value devices, thereby reducing the networking cost.
