I. Introduction
In this paper, we study a mobile system. The main purpose of our system development is providing users with practical, real-time, convenient service, which utilizes the behavioral characteristics of the mobile phone users and the particularity of the terminal. Among the many types of information, life information (such as food, clothing, shelter, transportation, and other aspects) search is one of the core mobile search business. The amount of outcome, obtained from life information search, is relatively smaller, but the accuracy is higher. And the user needs of living information search occur randomly. All of above are in line with the inherent characteristics of mobile terminals. On the other hand, life information search has strong purpose. Its contents are related to the user's daily lives, which involves the majority of consumer information. From this perspective, the life information search is very easy to form actual consumption behavior, so in terms of the cooperative business, it is also a good marketing opportunity.
