Abstract: In a multipoint mesh network, communications for establishing the network between multiple communication terminals may be coordinated such that connection request signals are not transmitted from both terminals in a pair of terminals to each other. In one example, a multipoint connection start terminal may be configured to request connections with each of the communication terminals participating in the mesh network. The multipoint connection start terminal may then receive a connection permission signal from each of the terminals to which a request signal was sent. The multipoint connection start terminal may subsequently generate terminal designation information specifying which terminals are to request connections with which other terminals so as to avoid communication overlap. This terminal designation information may then be transmitted to each of the other communication terminals participating in the mesh network.
