An electrical gateway and a communication method of the electrical gateway are disclosed. The electrical gateway includes: an uplink communication module, a downlink communication module and a control unit; the uplink communication module is configured to communicate with an uplink network element; the downlink communication module is configured to communicate with a terminal device; and the control unit, connecting the uplink communication module and the downlink communication module, is configured to, when it is determined that downlink data sent by the uplink network element is obtaining terminal device information, transmit the terminal device information to the uplink communication module if the terminal device information is stored in the electrical gateway, and transmit the obtaining the terminal device information to the downlink communication module if the terminal device information is not stored in the electrical gateway. Therefore, data communication is achieved.
