The Phs Packet Mode Data Communication Systems And Their Applications

Along with the communication development and the competition aggravating, in China's PHS network the rising rate of the telephone subscriber starts to slow down. PHS network operation companies faced with lacks growth points of new service, drops of the ARPU value, rising Churn rate and so on, faced with competition pressure comes from other telecommunication network operation companies. Take Packet Mode as the core , PHS packet data communication system can bring new vitality to the PHS network development. It will provide the operation company with the new point of service growth, the increase service income, enhancing the PHS product image, enhancing the user loyalty, the accumulation migration data service operation experience.The 2G PHS wireless data service uses the standard PIAFS. It takes the electric circuit exchange pattern as the foundation. The data transmission speed is 32kbps/64kbps. Under Packet mode, the channel resources are taken only then when the data are transferred. Thus, it enhances the resources use efficiency. Then, it enables the PHS network had the condition to enhance the data transmission speed, so as to develop many kinds of increment service on the foundation of data transmission.The purpose of the subject is to develop a packet data communication system in the existing PHS network to provide more efficient data communication between PS user and IP network by researching the related network solutions.The research of the subject involves telecommunication technologies such as packet data communication, network designation, mobile location, and wireless networks technology.First, the subject analyses the status of the existing PHS network, communication technologies such as the packet data communication, wireless location technology, provides the technical foundation for packet data communication system and the location service. Second, it sets up the whole logical frame structure, implements the basic function and provides application solutions for packet data communication system and the location service. Finally carries on the summary and the forecast.
