A method and device for data interaction

Abstract

The embodiment of the invention discloses a data interaction method and device. The method comprises: receiving a data request Probe Request transmitted from a terminal; analyzing original data in the Probe Request and transmitting the original data and a MAC address of the terminal to a server; and receiving a data response pocket carrying the MAC address of the terminal transmitted by the server, analyzing the response data in the data response pocket, and transmitting the response data to the terminal via a data response Probe Response according to the MAC address. By adopting a mode of transmitting data through the Probe Request and the Probe Response, i.e. a mode of performing data interaction through management frames, the data can be interacted under the condition that WIFI connection is not built between the terminal and the network node, so that the ultralow power consumption data interaction of the WIFI equipment can be realized.

Description

Technical field [0001] The present invention relates to the field of communication technology, and more specifically, to a method and device for data interaction. Background technique [0002] In the existing WIFI data interaction, the WIFI connection needs to be established first, and the data can be exchanged through TCP / IP based on the WIFI connection. The low power consumption of WIFI usually adopts the IEEE Powersave mode. When the AP is required to keep running at full speed, the data of each WIFI Station is cached, and then periodically notified to each Station through the beacon, and the Station needs to keep time synchronization with the AP, based on the beacon Wake up at intervals. However, there are some applications where the amount of data that needs to be transmitted is not very large, and the power consumption is very high. If you need to maintain a connection with the AP, you must wake up periodically, which consumes more power. If you do not maintain the connec...

Problems solved by technology

However, there are currently some applications that do not need to transmit a large amount of data and have high power consumption requirements. If you need to maintain a connection with the AP, you must wake it up periodically, which will consume more power consumption.

If you don’t keep the connection, you have to re-establish the connection with the AP every time you need to send data to work, and it takes a long time to establish the connection and consumes high power consumption.
