Data filtering system and method applied to mobile internet

Abstract

The invention provides a data filtering system applied to a mobile internet. The system mainly comprises a control surface module and a data surface module, wherein the control surface module achieves insertion or deletion of filtering rules, the data surface module achieves the functions of analysis of data messages, matching of the filtering rules and data forwarding, the control surface module interacts with the data surface module through shared memory, configuration of the rules is separated from matching of the rules, and the requirement for flexible configuration is met; meanwhile, the invention provides a data filtering method based on the data filtering system, a hash algorithm is combined with a bitmap algorithm, and flexible inserting or deletion and matching of the rules are achieved. In a signaling monitoring system or an internet surfing log management system, the function of internet surfing data filtering is achieved, rule configuration is separated from rule matching in processing through the control surface module and the data surface module, performance of a multi-core processor is sufficiently utilized, and high-performance real-time data filtering is achieved.

Description

technical field [0001] The invention relates to a data filtering system and method applied to the mobile Internet, which belongs to the field of mobile Internet PS packet domain data, and more specifically relates to a data filtering system and method of the mobile Internet. Background technique [0002] With the rapid development of broadband wireless access technology and mobile terminal technology, people are eager to obtain information and services from the Internet anytime, anywhere and even while moving. Mobile Internet has emerged and developed rapidly. Telecom operators meet more and more user needs by continuously improving or building new transmission networks (2G / 3G / LTE); at the same time, in order to provide better services, they usually establish signaling monitoring systems or online log management systems to use It is used to track traffic of specific cells, devices, users, business types (such as instant messaging, video playback / download, etc.) The stabilit...
