Method and device for switching NAN (Neighbor Awareness Network) network channels

Abstract

The invention discloses a method and device for switching NAN network channels. The process of the method executed at a mobile terminal side comprises: building NAN network connection on more than two channels between a mobile terminal and a routing device, wherein the NAN network connection built on the more than two channels is equipped with time synchronized discovery time windows; taking any one of the channels in the more than two signals in addition to the channel with lowest frequency as a main channel, interacting with a home device by the main channel; when the distance between the mobile terminal and the device of an opposite side is more than a corresponding distance threshold value, switching the main channel to a channel with relatively low frequency, controlling the home device by the channel with relatively low frequency, wherein the device of the opposite side comprises the routing device and / or home device. According to the invention, communication interrupt is avoided after switching among different channels through using the same synchronized time by the NAN network connection on different frequency bands, and the immediate effect of the control command of the mobile terminal on the home device is ensured.

Description

technical field [0001] The invention relates to the technical field of smart home connection control, in particular to a method and device for channel conversion of a NAN network. Background technique [0002] The Wi-Fi Alliance has formulated the standard specification of NAN (Neighbor Awareness Network, proximity discovery network). This specification aims at low power consumption and fast discovery of services provided by surrounding devices before establishing a connection. [0003] The NAN technology uses time synchronization to perform service discovery within the agreed discovery time window. Two types of messages are defined in the current standard: Beacon messages and service discovery messages. The beacon Beacon message is further divided into a synchronization Beacon message and a discovery Beacon message. Discovery Beacon messages are transmitted outside the discovery time window and are used to discover NANCluster. NANCluster is a group composed of multiple d...

Problems solved by technology

[0005] In the home domain, the mobile terminal is generally used as the controller to control the home equipment. Since the mobile terminal moves to a place far away from the home equipment in the home environment, the use of 2.4GHz channels may not be able to meet the communication needs, so it is necessary to use a lower frequency band channel for communication

[0006] However, the working time windows of different frequency bands in the NAN network are inconsistent, which will cause communication interruption after switching
