Design And Implementation Of Shanghai Mobile's Real-time Signaling Analysis System

Signaling is a kind of data for signing or controlling communication behavior in communication network. Signaling data need to be transmitted in the network. Signaling is a great deal of data which generate during the procession of communication operating. Signaling should be carefully studied because it implicates a wealth of information about subscriber's behavior and using habits.The location of mobile user call someone else can't be predicted before. Mobile operators understand mobile user less than fixed telephone subscribers. It is very difficult to analyze or predict user requirements. Is is a real obstacle to up-selling and cross-selling. The partial signaling data of operators is relevant with LACs and CELLs. LACs and CELLs are part of Geographic Information System (GIS). Signaling data not only can be used to solve the problem of lacking location information but also can be used to mining valuable knowledge. The result of signaling data analysis help operators understand correctly his customer segments. Thus the result can help operators to afford special services to customer segment with different characters also. The operators can get a dominance position in business competition.The author understood and studied A-Signaling and E-Signaling of SMCC(Shanghai Mobile Communications Company), explored contains business information, introduced high-performance computing technologies such as concurrent computing, inter-thread communication technology, I/O technology based on buffer, construction technology of line-shared-loop-buffer, construct and lookup technology about hash-table, high-performance read and write technology base on both file and network, high-performance timer technology etc. The author analyzed business requirements of the signaling analysis, designed real-time signaling analysis system, evaluated related technologies and achieved real-time analysis system for SMCC.The production in this paper is the design of Real-time Signaling Analysis System which is used to develop the target system. The system can analyze a great deal of signaling data instantly, and judge the campaign rules instantly, and trigger the real-time campaign activity based on location and communication behavior of subscriber. This system supported several real-time signaling analysis and campaign which got good results both on up-selling and cross-selling during World Expo (2010) of Shanghai, The products of Mobile-Expo-Newspaper and Mobile-Expo-ticket won more new customer than ever before. SMCC analyzed the current of tourist come from around the world, then provided real-time information to Shanghai World Expo Organizer about the amount and trend of visitors, And it was highly praised by the Shanghai Municipal Government.
