Embodiment Construction

[0036] The technical problem to be solved by the present invention is the character string positioning problem in the communication system, in this case, that is, the character string positioning problem in the seven-layer protocol analysis of content charging, and provides a method for character string search for URL analysis.

[0037] In order to solve the fast search and location of character strings, the method adopted by the present invention is to improve the BM (Boyer-Moore) method. The improvement made by the invention to the classic BM method makes it more suitable for solving the bottom character string positioning problem in content billing or other real-time communication systems. The main steps of the inventive method are as follows:

[0038] Step 1, preprocessing, performs preprocessing of the sliding span calculation on the character template that the system needs to find, and obtains the sliding span;

[0039] Step 2, configure the sliding span, form a structu...

Abstract

A method for positioning character string in communication system includes carrying out sliding span pretreatment on template character string to be sought in system and solving out sliding span, using a setting mode to form sliding span and template character string to be structured array and storing it into internal memory, fetching configured sliding span and template character string and seeking said template character string in sought text character string of system.

Description

technical field [0001] The invention relates to a method for searching or locating character strings in a communication system, in particular to the problem of fast locating character strings in a content charging system or a real-time system in the communication field. Background technique [0002] With the development and maturity of the mobile Internet, services transmitted through wireless media are developing towards diversification. After the arrival of the 3G system, this phenomenon will become more intense. Traditional billing methods based on duration or data traffic are no longer sufficient to meet the billing needs of the mobile Internet. The new generation of mobile Internet charging solutions will require the network system to distinguish and record the application services sent and received by users on the mobile system, that is, to charge according to the content. [0003] Content billing is mainly through in-depth data packet filtering and analysis on the u...
