COMMUNICATION MANAGEMENT METHOD, COMMUNICATION TERMINAL, COMMUNICATION MANAGEMENT PROGRAM, RECORDING MEDIUM CONTAINING THE COMMUNICATION MANAGEMENT PROGRAM, AND COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2003/026215

Kind Code:

A1

Abstract:

When a transmission station having a voluntary transmission right transmits a final frame as a TXOP end frame to HC, the HC transmits a transmission acknowledgement ACK after SIFS after the reception of the frame is complete. Here, when the transmission station has detected that no frame transmission is performed on the communication network by another ESTA between the final frame transmission end and the PIFS, the final frame is retransmitted between the frame transmission end and the DIFS. By performing such a communication management, it is possible to accurately perform management of voluntary transmission right even when the communication path reliability is low in a network in which one network path is time−division shared by a plurality of communication apparatuses
