PROBLEM TO BE SOLVED: To eliminate a radio terminal disconnected from all of other radio terminals on a network as a dropout radio terminal by discriminating whether or not the radio terminal is dropped out from the network based on system configuration information and discriminating the radio terminal disconnected from all of the other radio terminals on the network. SOLUTION: System configuration information of a radio terminal I in Fig. (d) sets '5' as the number of times of communication to a radio terminal J, but there is no number '4' set to the same system configuration information and then the number '4' is not consecutive to the numbers listed in the system configuration information. If the radio terminal J connects with a network via other radio terminals in the network, there should be a terminal where '4' is set as the number of times of communication from the radio terminal I with respect to the radio terminal having a direct communication channel to the radio terminal J. However, there is no terminal where '4' is set as the number of times of communication and then it is discriminated that the radio terminal J is a dropout terminal that is not in existence on the network. |
