Abstract:
1. A mobile communication equipment, comprising: a primary module, comprising a first connector, a processing unit and a switching unit, wherein the first connector at least comprises a first instruction transmission pin and a first data transmission pin, the processing unit is respectively connected to the first instruction transmission pin and the switching unit, the switching unit connected to the first data transmission pin comprises a plurality of transmission units with different transmission speeds; and a secondary module connected to the primary module and comprising a second connector capable of transmitting with a specific transmission speed, wherein the second connector comprises a second instruction transmission pin corresponding to the first instruction transmission pin and a second data transmission pin corresponding to the first data transmission pin; wherein, when the primary module is connected to the secondary module, the processing unit transmits an inquiry instruction to the secondary module for inquiring into the specific transmission speed of a transmitting from the secondary module; the secondary module then transmits a reply instruction for responding the specific transmission speed of the transmitting from the secondary module; the switching unit switches to one of the transmission units thereof with which the transmission speed matches the specific transmission speed of the transmitting from the secondary module according to the reply instruction.
