Network access control method and service gateway

Abstract

The invention provides a network access control method and a service gateway. The network access control method comprises that: if the service gateway judges a network resource address does not meet a filtration-free operation condition after receiving a network resource address access request from a user, the service gateway filters harmful information out of network resource contents corresponding to the network resource address, provides the filtered network resource contents to the user, computes a harmfulness degree value of the network resource contents and updates the filtration-free operation condition according to the computed harmfulness degree value. In the method, the filtration-free operation condition is automatically updated according to the harmfulness degree value so as to adaptively run the whole filter system and improve network address access processing efficiency. In addition, when the user repeatedly makes requests for accessing the network contents of which the harmfulness degree value is greater than a preset threshold value, the service gateway directly refuses the access of the user without acquiring the network contents from a service provider and performing repeated filtration operation on the network contents for a plurality of times, so the network address access processing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for controlling network access and a service gateway. Background technique [0002] The Wireless Application Protocol (WAP) service is a service provided by operators to mobile users to access the Internet through mobile phones. Some users who are not convenient to use computers can browse the services of WAP sites through the WAP browser of their mobile phones, and then enjoy various application services such as news browsing, stock inquiry, mail sending and receiving, online games, and chatting. And with the advent of the 3G era, the bandwidth of information transmission increases, and the information disseminated by mobile phones becomes more diverse. Users can enjoy richer network services such as video, voice, and images. [0003] WAP technology brings users the convenience of enjoying the network, and also provides a new way of disseminating bad info...

Problems solved by technology

[0006] When a user accesses the same network content containing bad information multiple times, the service gateway performs the same filtering operation on the same content, resulting in a waste of multi-pass processing capacity of the service;
