Dynamic switching device and method for mobile terminal data mode

A mobile data terminal mode dynamic switching method and apparatus, the apparatus includes a terminal status monitoring module for monitoring the state of the mobile terminal, to monitor whether there is data transmission in a data transmission monitoring module, data transmission module, monitors the input operation of input monitoring module, an input module, a data switching control mode of the control module, and baseband communications module, said method comprising the steps of: within the set time, it is determined whether the mobile terminal is in an idle state; within the set time, the mobile determines if the terminal has a data transmission; the data pattern of the mobile terminal to switch to data mode 2G. Dynamically switching method of a mobile terminal apparatus and a data pattern of the present invention, when the mobile terminal within the set time both idle, but no data transmission, the automatic mode is switched to the data mode data 2G, the mobile terminal reduces the data interface standby current in the inactive state, the use of extended time.
