Energy saving method for enabling mobile terminal and wireless access point to be correlated and device

Abstract

The embodiment of the invention discloses an energy saving method for enabling a mobile terminal and a wireless access point to be correlated and a device, which can be applied to a mobile terminal. The method comprises steps: when entering a wireless local area network is realized and a beacon sent by the wireless access point is not scanned, a self wakeup signal transmission module is used for broadcasting a wakeup signal externally, and thus after the wireless access point receives the wakeup signal via the self wakeup signal receiving module, a response signal is fed back to the mobile terminal; the response signal fed back by the wireless access point is received; a target wireless access point in data communication with the mobile terminal is determined; and correlation between the mobile terminal and the target wireless access point is built, and data communication is carried out. When the embodiment of the invention is applied, after the wireless access point receives the wakeup signal transmitted by the mobile terminal, a CPU and a wireless network card are only waked up to be in a working state, correlation with the mobile terminal is thus built, data communication is carried out, and energy consumption of the wireless access point in the wireless local area network can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to an energy-saving method and device for associating a mobile terminal with a wireless access point. Background technique [0002] As the scale of WLANs continues to expand, the density continues to increase. The number of network devices, especially APs (Wireless Access Points, wireless access points) in the wireless local area network also increases sharply. [0003] At present, in order to ensure that mobile terminals (such as mobile phones, tablet computers, notebooks, etc.) entering the wireless local area network are connected to the Internet for data communication in time by associating with a certain AP, the wireless network card of the AP needs to periodically send out beacons. The terminal scans out available APs according to the beacon, and then selects an AP with the strongest signal strength for association according to the signal strength of the AP, ...

Problems solved by technology

[0004] However, in the actual large-scale and high-density wireless LAN environment, most APs do not have mobile terminals associated with them for a long time and communication data needs to be processed, and the wireless network card of the AP also periodically sends out beacons, which consumes more energy; And when the wireless network card sends out beacons, the CPU of the AP needs to be in the working state, which also consumes more energy. The energy consumption of the wireless access point AP has become a concern of the communication industry.
