The present application provides a data transmission method and device, which are applied to wireless networks. The method includes: a workstation receives a part of a beacon frame, and performs frame check sequence calculation on the credible fields in the part of the beacon frame to obtain the current calibration check code; the part of the beacon frame includes the part of the beacon frame from the frame header to the flow indication segment; the workstation compares the current check code with the historical check code to determine whether the current check code is It is consistent with the historical check code; if the current check code is consistent with the historical check code, the workstation analyzes the flow indication segment to determine whether there is cache data in the wireless access point; when the wireless access point has cache data data, the workstation receives the buffered data and the remaining beacon frame, and after the reception is completed, the workstation switches to a dormant state; the remaining beacon frame includes the part of the beacon frame after the traffic indication segment.
Description
technical field [0001] The present application relates to the technical field of wireless networks, and in particular, to a data transmission method and device. Background technique [0002] Nowadays, with the rapid development of wireless network technology, the corresponding low power consumption technology has become a major research direction of relevant researchers. At present, the low power consumption technology of most wireless networks usually refers to the method defined in the IEEE802.11 standard, and in the actual use process, most of the beacon frames sent by the wireless AP (Access Point, access point) are There is no logo cache, so in most cases the sleep process of the workstation is to wake up according to the beacon frame cycle, analyze the data cache logo in the beacon frame, check whether there is data to receive, and notify the wireless if there is data to receive AP sends cached data, if not, it goes to sleep. [0003] In the prior art, the TIM (Traff...
