Problems solved by technology

In addition, when the device is connected to a wireless router, it needs to go through at least four processes of discover / offer / request / ack of DHCP. However, due to different routers and different environments, the duration of each process of DHCP will be uncertain or a certain amount of DHCP will be increased. These processes, so that the entire DHCP process may be very long in some scenarios

Abstract

Embodiments of the present application provide an IP address lease renewal method, device, network system, and electronic equipment. The first device receives the IP replacement request sent by the second device, and the first device establishes a connection with the wireless router; then obtains the IP configuration information of the second device, and the IP configuration information is provided by the wireless router Assigned to the second device; then create a DHCP broadcast packet based on the IP configuration information of the second device; and then periodically send a lease renewal request including the DHCP broadcast packet to the wireless router. This method can realize that the second device can be assigned the same dynamic IP address as the last time it was working, so that it can quickly connect to the wireless router, and the power consumption of the second device can be reduced and the battery life can be extended during the power outage period of the second device. service life.

Description

technical field [0001] The present application relates to the technical field of communications, and more specifically, to an IP address renewal method, device, network system and electronic equipment. Background technique [0002] DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) enables the server to dynamically provide IP (Internet Protocol, Internet Association) addresses for other hosts in the network, and does not need to provide DHCP, DNS ( Any server other than Domain Name System (Domain Name System) and WINS (Windows Internet Name Service, Windows Network Name Service) server sets and maintains a static IP address. A device with a wireless network card can be assigned a dynamic IP address by connecting to a wireless router through WiFi, but a dynamic IP address has a lease time. Once the IP address lease expires, the wireless router will recycle the IP address. And assign it to any device that connects to the wireless router next time....
