摘要

The group identifier of the message received by each communication terminal is referenced and the life value of the message is compared with a predetermined initial value. As a result, the distance between the group to which a communication terminal having transmitted the message belongs and a communication device is grasped to obtain the distance between the groups to which communication terminals connected within the communication device and a predetermined distance through a link belong and the communication device for each direction to hold it as connection link management information. The number of communication terminals belonging to a specific group within the predetermined distance and the distance between them and the communication device for each direction on the basis of the connection link management information are provided as priority information on the specific group.
