Claim:
1. A communication module for implementing hot plug, comprising a new-generation Mini-Peripheral Component Interconnect Express (PCIe) interface configured to be connected to a host system, and further comprising: a power switch, configured to control connection and disconnection between a power source end of the communication module and a power supply end of the host system; a charging unit, configured to generate a charging current when the power switch is turned off, to raise a power source voltage of the power source end of the communication module; a delay unit, configured to generate a predetermined delay, and to control turning on of the power switch according to the predetermined delay; and an ON/OFF control unit, configured to control ON/OFF of the communication module according to a control signal output by the host system after the power switch is turned on, wherein the charging unit, the power switch, the delay unit and the ON/OFF control unit are separately connected to the new-generation Mini-PCIe interface, the power switch is connected to the charging unit, and the charging unit is connected to the power source end of the communication module; and wherein the length of a data pin of a universal serial bus (USB) of the new-generation Mini-PCIe interface is shorter than the length of a power source pin of the USB by a predetermined value, the predetermined value is ⅓ of the length of the power source pin, and the communication module is a third-generation (3G) module.
