Problems solved by technology

[0003] During the research process, the inventor found that the surge of mobile network broadband data traffic has put forward higher requirements for bandwidth, and operators need to deploy more expensive SGSN, GGSN, VAS equipment and expensive links between equipment, As a result, the cost of network expansion is greatly increased. Therefore, it is necessary to provide low-cost mobile service solutions

Embodiment Construction

[0018] An embodiment of the present invention provides a network traffic distribution system, such as figure 2 As shown, the system includes a base station, a radio network controller RNC, a serving GPRS support node SGSN, a gateway GPRS support node GGSN, a value-added server VAS and the Internet and other networks, but some embodiments of the present invention may require SGSN and / or GGSN The function is extended, and the specific extension can be reflected in the subsequent method description. In addition, the system also includes a distribution device and a policy server. The policy server may be a Policy and Charging Rule Function (Policy and Charging Rule Function, PCRF) or other devices capable of providing charging and offloading policies. When using the above-mentioned network traffic distribution system for data transmission, it is first necessary to establish or obtain the charging policy of the user through the signaling plane (shown by the dotted line in the fig...

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, and forwards the data stream according to the offloading policy, where the obtaining the offloading policy of the user includes: obtaining the offloading policy of the user from the offloading device and / or obtaining the offloading policy of the user from a policy server. 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 such as SGSN, GGSN, and VAS, thereby reducing the networking cost.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method, device and system for offloading network traffic in mobile communication. Background technique [0002] A typical networking of the current mobile network is as follows: figure 1 As shown, including a base station, a radio network controller (Radio Network Controller, RNC), a serving general packet radio service (General Packet Radio Service, GPRS) support node (Serving GPRS Support Node, SGSN), a gateway general packet radio service GPRS support node (Gateway GPRS Support Node, GGSN), Value-Added Server (Value-Added Server, VAS) and Internet and other networks. Wherein, the base station is used for two-way transmission and reception of wireless signals. The RNC is an integral part of the access network and is used to provide mobility management, call processing, link management and handover mechanisms. SGSN provides the connection with the radio...
