Distributed wireless gateway system and communication method

Abstract

The invention relates to a distributed wireless gateway system and a communication method. The system is provided with the following structures: a third-grade access gateway, a second-grade access gateway, a access main gateway, an outer network control server and an inner network control terminal, wherein the access main gateway is wirelessly connected with the second-grade access gateway and the inner network control terminal and used for providing an access protocol interface with an outer network; the outer network control server and the inner network control terminal are used for providing the generation of control instructions and / or media data for a human-computer interaction interface, maintaining state information of a terminal device and monitoring whether the access main gateway is capable of normally working or not, if the access main gateway can not work normally, the inner network control terminal is directly communicated with the two-grade access gateway in a bridging way. As the system is provided with the outer network control server and the inner network control terminal, so that a network architecture of network inner and outer double-backup is formed, and when the access main gateway can not work normally because of a fault and the like, the inner network control terminal can be directly communicated with each second-grade access gateway; problems of bandwidth and channel interference in dense spectrum communication can be effectively solved by using the third-grade access gateway, and the reliability of the distributed wireless gateway system is greatly improved.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a distributed wireless gateway system and a communication method, which is especially suitable for the field of family informatization where 3C is integrated. Background technique [0002] With the development of network technology and wireless communication technology, distributed wireless access technology and various devices derived from it are becoming more and more popular in various fields of life and work. The most common architecture of a distributed wireless access system includes multiple wireless access points and multiple wireless terminals. On the one hand, each wireless access point can establish a connection with an external network through a wired transmission medium or a wireless transmission medium; on the other hand, each wireless access point establishes a connection with one or more wireless terminal devices through a wireless transmission medium. ...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art and provide a distributed wireless gateway system. The equipment is uniformly configured by the control terminal in the network, and when the main access gateway fails to work normally due to failure or other reasons, the control terminal in the network can directly communicate with each secondary access gateway, and directly provide control instructions and / or or data generation, in order to realize the control of each terminal equipment, and the communication between the terminal equipment in the network and the external network is realized by accessing the main gateway and adopting a unified access protocol, which reduces the cost and complexity of networking, and also makes The reliability of the system is greatly improved. In addition, the present invention adopts three-level access gateway technology, so that the load distribution of each level of access gateways is relatively average and the service life is longer.
