Abstract

The present invention discloses a home gateway and an automatic power-off method thereof, and relates to the home gateway field. The home gateway assigns IP addresses to internet terminals, stores all assigned private network IP addresses into a private network IP address list, detects on-line states of the internet terminals in real time, retrieves private network IP addresses of the internet terminals at an off-line state, and automatically powers off under the condition that the private network IP address list is empty, thereby realizing automatic power-off of the home gateway according to internet-surfing behaviors of users, timely releasing public network IP addresses when the users are not using the internet, lowering equipment energy consumption and reducing indoor safety loopholes.

Description

technical field [0001] The invention relates to the field of home gateways, in particular to a home gateway and an automatic shutdown method thereof. Background technique [0002] Broadband networks have widely covered urban home users, and home gateways with Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol, DHCP) routing functions and Wireless Fidelity (Wireless Fidelity, WIFI) functions are gradually becoming mainstream. [0003] The existing home gateway is usually in routing mode, that is, it will automatically initiate a dialing request once it is turned on, and obtain a public network Internet Protocol (Internet Protocol, IP) address allocated by the operator after a successful connection. If the home gateway is always working, it will always occupy the public IP address. At present, when users do not access the Internet, they usually manually close the home gateway. [0004] However, in home use scenarios, the following problems often occur: ...
