Embodiment Construction

[0064] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0065] In the embodiment of the present invention, the wireless system status of the gateway and the terminal is as follows figure 1 As shown, when the gateway establishes a network, it will select a working frequency band in the current airspace, and use a unique personal area network identity PanID to identify the gateway as a network in the personal area network. After the creation is successful, it will enter normal work state. The...

Abstract

The invention discloses a method, device and system for pairing a gateway and a terminal to solve a problem that the terminal and the gateway are required to be the same frequency band in a conventional pairing mode and a pairing error occurs because of frequency band overlapping when a plurality of terminals and the gateways are paired. The method comprises the following steps: the terminal is in an initial pairing state, receives and analyzes broadcasting packets successively in each frequency band at intervals of first set time length, determines the broadcasting packets carrying preset pairing codes, and establishes a pairing connection with a gateway selected from the gateways corresponding to the broadcasting packets carrying the pairing codes; the terminal is in a state for being paired with the gateway again, determines that historically paired gateway information is stored, receives and analyzes the broadcasting packets successively in each frequency band at intervals of third set time length, wherein the broadcasting packets carry the gateway information transmitting the broadcasting packets, determines a frequency band corresponding to the broadcasting packets paired with the historically paired gateway information, and establishes a paired connection with the gateway corresponding to the determined frequency band.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method, device and system for pairing a gateway and a terminal. Background technique [0002] Wireless Personal Area Network (WPAN) is an emerging short-distance wireless communication network technology proposed in order to achieve small activity radius, rich business types, and seamless connection for specific groups. [0003] At present, the communication between short-distance wireless systems requires the operation process of pairing (or binding) between the terminal and the gateway first, so that data interaction or function control can be performed between the successfully paired gateway and the terminal, and only the pairing Only successful gateways and devices can communicate normally. [0004] The commonly used pairing method is: when the gateway and the terminal enter the pairing mode of the same frequency band, the terminal sends a pairing request to ...
