Clustering terminal initialization method and system, central device and clustering terminals

The invention discloses a clustering terminal initialization method and system, a central device and clustering terminals. The clustering terminal initialization method comprises the steps that a call number configuration table stored in the central device is read; a call number distribution signal is sent to a designated base station through a control channel; the designated base station is controlled to send the call number distribution signal to the clustering terminals one by one through the control channel, and response information, returning through the designated base station, of the clustering terminals are received, wherein the steps are executed by the central device. The clustering terminal initialization method further comprises the steps that the designated base station is locked, and the clustering terminals are in the leisure standby state in the designated base station wireless coverage area; the call number distribution signal from the designated base station is received through the control c
