WIRELESS PACKET COMMUNICATION TRANSMITTING METHOD AND WIRELESS PACKET COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a wireless packet communication system capable of periodically transmitting data having real time performance and controlling the data while reducing the influence of errors generated on a transmission path on communication quality. SOLUTION: There exist a plurality of service classes which have different priorities corresponding to communication quality provided to transmitted data in transmitting and receiving the data between wireless base station and wireless terminal stations. The base station has a priority managing means for managing information about the priority of data transmitted from the terminal stations under its control. The base station and terminal stations each have, in a transmission buffer, a plurality of transmission queues having different priorities according to service classes for transmission of the data. To transmit QoS(Quality of Service) data in a wireless section, the base station is provided with a cycle management means for managing time intervals to carry out polling periodically.
