Method and device of realizing device search

Abstract

The present invention discloses a method of realizing device search. The method is applied to a network terminal device in a local area network, and comprises the steps of broadcasting an online notice message in the local area network after accessing in the local area network, wherein the online notice message carries the device information and the authentication information of a device; after the online notice messages sent by other devices in the local area network or a response message of an online notice of the device are or is received, authenticating the other devices according to the authentication information of the other devices carried in the messages, if the authentication passes, according to the device information of the other devices, adding or updating the device recording in a device list; displaying the device list. According to the present invention, the network terminal device in the local area network can search the other devices in the network conveniently. The present invention also discloses a device of realizing the device search.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for realizing device search. Background technique [0002] With the development of the Internet, various network terminal devices such as laptops, PCs, smart phones, tablets, and smart set-top boxes have become necessities in people's work and life. In daily life, multiple network terminal devices often form a local area network. However, for mobile network terminal devices (such as notebooks, smart phones, tablet computers, etc.), they may be connected to different local area networks within a day. [0003] Since mobile network terminal devices often switch between different local area networks, if a fixed IP address is used, it is easy to cause IP address conflicts. Moreover, with the increase and frequent changes of internal devices in the LAN, it also makes it a heavy task to specify an IP address for each device. Therefore, a common pract...

AI Technical Summary

Problems solved by technology

[0005] It can be seen that manually checking the IP address of the network terminal device to search for the device will make the operation cumbersome, and it is not conducive to some automated operations

Especially with the development of the Internet of Things, more and more devices are connected to the LAN, and some devices may not be able to view the IP address conveniently.
