A communication terminal device, a communication system, a communication method, and a program which can realize the functions of joining and exiting from a network in the middle of communication, detecting disappearance of stations (communication terminals), and/or changing over a coordinator function. The communication terminal has the capabilities of: detecting disappearance of a coordinator in the network by lack of reception of beacons and frames from other terminals, and, if its transmission timing at a certain TBTT is the shortest within a network, serving as a new coordinator itself to transmit beacons; and serving as a communication-holding coordinator having entered a predetermined mode, and transmitting a change request frame to a communication terminal to which changeover of a coordinator function is requested, thereby transferring the coordinator function to a communication terminal not functioning as the coordinator. |
