Advanced Intelligent Networks (AIN's) are telecommunications networks that are capable of providing advanced services through the use of distributed databases that provide additional information to call processing and routing requests. The Advanced Intelligent Network (AIN) is a combination of the SS7 signaling network, interactive database nodes, and development tools that allow for the processing of signaling messages to provided for advanced telecommunications services. In this paper, the authors explore the general architecture of AIN. They also explain the role of AIN for mobile communication. The proposed idea in this paper are two major directions in AIN for mobile communications which are wireless access technology and increased network functionality.
