Location-based multimedia information pushing method in wireless local area network and pushing system thereof

The invention relates to a location-based multimedia information pushing method in a wireless local area network and a pushing system thereof. A control device FC (Fiber Channel) is connected in series between a wireless access point node AP and an access controller AC, a certification process between the AP and the AC is changed, and multimedia information pre-stored in the FC is added in contents returned by a certification server connected with the AC. By adopting the location-based multimedia information pushing method, the problems of in construction, maintenance and operation of the WLAN (Wireless Local Area Network) of the existing telecommunication operator can be solved. The method can be used for pushing advertisements for hotspot owners, and the enthusiasm of the owners can be aroused. The invention has the advantages of fewer risks in transformation of the existing network, low technical difficulties and step-by-step stable implementation.
