Abstract

The invention discloses a cluster gateway implementation method of a TDMA wireless ad hoc network. The invention adopts the following steps that after successful networking, an ad hoc network cluster gateway waits on a cluster control channel of even time slot and monitors odd time slot of the ad hoc network, and after receiving relevant service channel allocation signaling of the cluster system or when receiving relevant service signaling of the ad hoc network, a service request is initiated to the cluster system and the service channel allocation signaling of the cluster system is received, and a proper ad hoc gateway link node is selected according to parity of the service channel to transmit the service signaling of the ad hoc network to the cluster network or transmit the service signaling of the cluster network to the ad hoc network. The method has the advantages that the method can communicate the cluster network with the self-organizing network service without changing any communication mode of the cluster network, and the self-organizing network and the cluster network can work on the same TDMA time sequence, so that information in the self-organizing network and the cluster network does not have any delay.

Cluster gateway implementation method of TDMA wireless ad hoc network Technical Field The invention relates to the technical field of communication electronics, in particular to a cluster gateway implementation method of a TDMA wireless ad hoc network. Background The common use modes of professional wireless communication are three modes of conventional direct communication, conventional transfer communication and cluster communication. The former conventional pass-through mode requires only mobile station equipment, such as interphones and/or car stations, to conduct traffic, such as calls, directly between 2 or more mobile stations. Conventional through-connection is extremely limited in coverage due to the linear propagation characteristics of the radio frequency. The latter two modes require the establishment of a base station, and the communication coverage area can be enlarged by the base station forwarding the service. Where a trunked communication system typically establishes a plurality of base stations covering a larger area. Due to the limitation of topography, the trunked communication system always has places which are not covered, such as the field, mountain/tunnel, basement and the like, which often have no base station signals or are not easy to erect base stations, and the places can use the ad hoc network technology to realize the remote communication problem of the places through the networking among mobile stations.
