Method for establishing bidirectional data transmission paths in a wireless meshed communication network

The invention relates to a a two-way transmitting data in a communication network of wireless alternately packet-switched method, provided at least one route shape of tree to a logic topology on the first type; and multicast tree of network node (R) and a main directory searching message (RAN) and periodic time-gap to the communication network node (M1-M7); the main directory searching message assigns to the root network node (R) first one-way data transmission device, and multicast tree network node (M1-M7), which is mounted on the two first rate of different the relay, and is put in the first a selectableThe first (a), network node (M5) in the main directory searching message (RAN) is a response message (RWN) are network node (R), the routing response message assigns to the network node second one-way data transmission device, thereby (M5) and a two-way transmitting data routing between two network node (R) and network node.
