A mobile terminal, comprising: at least one processor; and at least one memory, wherein the at least one memory is configured to store instructions and data, and the at least one processor is configured to execute the steps of: monitoring an occupancy rate of time slots in a network by the mobile terminal; marking a predetermined number of the time slots as first time slots and marking the rest of the time slots as second time slots, in response to the occupancy rate of the time slots being lower than a predetermined threshold; and assigning one of the first time slots as a dedicated time slot which is only used for data communication when the data communication proceeds; releasing the one of the first time slots when the data communication ends; characterized in that the at least one processor is further configured to execute the steps of: monitoring the occupancy rate of the time slots in the network continually; and processing, in response to the occupancy rate of the time slots being greater than or equal to the predetermined threshold, the time slots which are marked as the first time slots and occupied as follows: duplicating data in the time slots which are marked as the first time slots and occupied into the second time slots for communication; and releasing the first time slots and marking the same as the second time slots after 2 seconds after the step of duplicating the data in the time slots which are marked as the first time slots and occupied into the second time slots for communication is performed. at least one processor;
