The evolution of mobile communications has been rapidly popular in recent years. In Taiwan, mobile phones predominantly possess multiple functions. In other words, mobile phones are not only conventional phones but also smart computer systems embedding with intelligent agent mechanisms to integrate heterogeneous applications. In addition, the billing system (Customer DB, Tariff and Sharing Schemes, Rating and Bill Data) is the crucial part of the communication system. It is an independent system to calculate the fee of communication. There are a lot of applications embedded into the mobile device in the market; however, how to integrate the billing system with the applications is insufficient. This study uses the RFID characteristics and intelligent agent attributes to establish a communication channel in order to automatically transmit data packets from the source site to the destination site. It exploits the intelligent agents to combine the intelligent parking system and the billing system. In addition, it proposes four kinds of intelligent behavior models including the intelligent agent cooperation behavior model, communication behavior model, coordination behavior model and competition behavior model to improve the process more smoothly and automatically. Using the intelligent agent characteristics and integrating the RFID features with the billing system are the most significant key factors. The proposed method improves the process, reduces the management cost and provides more flexible, stable and available systems.
