METHOD FOR CONTROLLING NETWORK ACCESS AND SERVICE GATEWAY THEREOF

摘要

The present invention discloses a method for controlling network access and a service gateway thereof. The invention includes that after the service gateway received the user access request for a network resource address, when the network resource address is determined that it does not satisfy the filter-free operation conditions, the network resource contents corresponding to the network resource address are provided to the user after the vicious information is filtered, and the vicious degree values of the network resource contents are calculated, then the filter-free operation conditions are updated according to the calculated vicious degree values. In the present invention, by the automatic update of the filter-free operation conditions according to the vicious degree values, the whole filter system operates adaptively, and the processing efficiency of the network address access is improved. In addition, when the user repeatedly requests the access of the network contents whose vicious information value is above the pre-set threshold, the service gateway does not need to obtain the network contents from the service provider but refuses the user access directly, thus the processing efficiency of the network address access is improved without the repeat filter operation in several times for the network contents.
