Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with accompanying drawings and examples.

[0030] In recent years, with the popularization of mobile terminal equipment and the development of wireless communication technology, more and more users use mobile devices to access the network, among which Wi-Fi (802.11) is the most mainstream wireless network, almost all mobile devices Equipped with a Wi-Fi interface, most users use Wi-Fi to surf the Internet. Normally, if a user wants to obtain a Wi-Fi connection, he needs to start Wi-Fi to scan the surrounding APs in advance, and then select a specific AP to connect to. However, Wi-Fi scans often take a long time (3-5 seconds) and consume a lot of power, and usually many scans are useless, especially for the situation where there are no Wi-Fi APs deployed around. ZigBee is a short-distance, low-complexity, low-power consumption, low-response delay, and low-cost two-way wireless communication t...

Abstract

The invention discloses a ZigBee-based Wi-Fi access point discovering and selecting method. In the method, an area in which a plurality of access points (AP) and a plurality of sets of mobile portable equipment are deployed serves as an application scene, and ZigBee is adopted as a communication link. The method comprises the following steps of: initializing and establishing a Wi-Fi AP list first; then starting a ZigBee interface for receiving data and starting two timers; when the ZigBee interface receives the data, extracting AP information and updating the AP list; when the two timers are overtime, respectively performing the operations of updating the AP list and broadcast AP information; and when a connection request is received, performing connection request processing. By using the method, the AP information can be shared among mobile equipment through the ZigBee interface; the mobile equipment is connected to related AP directly by using the AP information without scanning the AP in advance; a current optical AP is selected for connecting according to the AP information; therefore, the AP scanning times are reduced greatly and the power consumption of the Wi-Fi interface is reduced effectively.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a ZigBee-based Wi-Fi access point discovery and selection method. Background technique [0002] Wi-Fi (also known as 802.11b) is a wireless communication technology that works in the ISM (Industrial Scientific Medical) frequency band of 2.4GHz and uses DSSS (Direct Sequence Spread Spectrum) spread spectrum technology to provide a maximum rate of 11Mbps and an effective distance Up to 100m, it has the characteristics of fast speed, large communication range and low cost. Due to its advantages of high bandwidth and low cost, Wi-Fi has become the mainstream of wireless communication, and most mobile devices are equipped with Wi-Fi interfaces. [0003] However, Wi-Fi also has the disadvantage of high power consumption. Research data shows that more than 50% of the power consumption of mobile devices comes from Wi-Fi interfaces, so mobile devices will not be able to support lon...
