The application provides an
online method and
system of a terminal and a computer readable medium. The method comprises the following steps: obtaining the current latest terminal information matching table through a factory
base station;
polling the terminal which has not entered the factory and is online in the latest terminal information matching table according to a
polling period; sending a call
package to the polled terminal; updating the state of the polled terminal in the terminal information matching table to the state of having entered the factory and being online if the response
package replied by the polled terminal is received within a preset time length; and
broadcasting the updated terminal information matching table to the
base station accessing the factory network through the factory network, so that the positioning
base station updates the factory terminal dynamic
list according to the updated terminal information matching table, and communicates with the terminal which has entered the factory and is online in the factory terminal dynamic
list according to the
polling period, thereby reducing the call time consumption of the terminal which has not entered the factory and is online, and shortening the polling period of the positioning base
station.
