[0061] figure 1 It is an explanatory diagram of a configuration example of the wireless communication system 100 according to the first embodiment of the present invention. The wireless communication system 100 of this first embodiment includes an administration terminal (AP) 110 and a plurality of communication terminals 120 . As specific application examples of the wireless communication system 100 , the product management system and school commute system described in the background art can be considered. figure 1 In , the case where the three communication terminals 120 move in the direction of the arrows with the passage of time and cause state transition is represented by the main intervals 101-105.

[0062] The present invention is characterized in that each of the plurality of communication terminals 120 forms a group connected to the network from a communication terminal (terminal STA) before authentication to an authenticated communication terminal (authentication ...

[0131] Figure 13 It is an explanatory diagram of a configuration example of the wireless communication system 1300 according to the second embodiment of the present invention. The wireless communication system 1300 of this second embodiment is different from the above-mentioned wireless communication system 100 although it further includes an assistant administration terminal (AAP) 1310 . Hereinafter, the second embodiment will be described focusing on the processing related to the auxiliary management terminal 1310 . In addition, the configuration of the wireless communication system 1300 that performs the same processing as that of the wireless communication system 100 is assigned the same reference numerals and description thereof will be omitted.

[0132] Figure 13 In , the main intervals 101, 1302, and 103-105 show the situation that the three communication terminals 120 move in the direction of the arrows with the passage of time and produce state transitions. Such ...

Abstract

A beacon is transmitted and received among a plurality of terminals STA. A terminal STA which transmits the beacon is assigned as a representative terminal MSTA which manages a group, and a terminal STA which receives the beacon is assigned as a belonging terminal SSTA of the group. The representative terminal MSTA obtains identification information from the belonging terminal SSTA and stores the identification information. Then, when receiving an AP beacon from a management terminal AP, the representative terminal MSTA collectively transmits, to the management terminal AP, the identification information of the representative terminal MSTA and the belonging terminal SSTA. The management terminal AP performs an authentication procedure, by using the collectively transmitted identification information, for each of all of the communication terminals which form the group.

Description

technical field [0001] The present invention relates to a wireless communication system using a wireless network including multiple terminals such as sensor networks and active RF tags, communication terminals and management terminals constituting the wireless communication system, a communication method executed by the wireless communication system, and integrated An integrated circuit that implements the functions of a communication terminal or a management terminal. Background technique [0002] In recent years, network systems employing small-sized and low-power-consumption wireless communication terminals such as wireless personal area networks (WPAN, Wireless Personal Area Network) and sensor networks have attracted attention. In addition, as a system similar to this, there is a network system that uses an active RF tag that itself transmits a wireless signal as a wireless communication terminal. [0003] Since these network systems can centrally manage a plurality of...
