Electrical gateway and communication method of electrical gateway

An electrical gateway, comprising:

• an uplink communication module;
• and
• a downlink communication module,
• wherein the uplink communication module is connected to the downlink communication module;
• wherein the downlink communication module is configured to communicate with a terminal device;
• and
• wherein the uplink communication module is configured to:
• determine that downlink data sent by an uplink network element is obtaining terminal device information, send the terminal device information 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.

A communication method of an electrical gateway, comprising:

• receiving downlink data sent by an uplink network element;
• and
• when determining that the downlink data is obtaining terminal device information, transmitting the terminal device information to the uplink network element if the terminal device information is stored in the electrical gateway;
• transmitting the obtaining the terminal device information to a terminal device if the terminal device information is not stored in the electrical gateway.
