Embodiment 1

[0038] According to an embodiment of the present invention, a method for sending wireless frames is provided. After a station enters an awake state from a dormant state, it selects a preset access level or a pre-negotiated access level with the central station to compete for a wireless channel, and passes the obtained wireless channel Sending to the central site a wireless frame notifying the central site to send buffered data to the site, so that the site can flexibly and dynamically adjust the access level used for sending the wireless frame.

[0039] figure 1 is a flow chart of a method for sending a wireless frame according to an embodiment of the present invention, such as figure 1 As shown, the method may include the following steps (step S102-step S104):

[0040] Step S102, when the station enters the awake state from the dormant state, it selects a preset or pre-negotiated access level with the central station to compete for the wireless channel;

[0041] Step S104, ...

Embodiment 2

[0056] Aiming at the problem of how to send the wireless frame used to notify the central station to send data when the station with high power saving requirements in the related technology works in the active inquiry mode, so as to improve the power saving capability and provide higher flexibility and controllability, currently No effective solution has been proposed yet. According to an embodiment of the present invention, a scheme is provided in which the station and the central station negotiate to configure the access level of the wireless frame used to notify the central station to send data in the power-saving mode of the wireless network and perform data transmission, so as to solve the problem of enhanced Technical issues with power saving capabilities.

[0057] To achieve the above purpose, in the embodiment of the present invention, a data transmission method in power saving mode based on a negotiated access level is taken as an example for description.

Abstract

The invention discloses a method and a device for sending wireless frames. Wherein, the method includes: when the station enters the awake state from the dormant state, selects a preset or pre-negotiated access level with the central station to compete for the wireless channel, and sends a wireless frame to the central station through the competed wireless channel, and notifies the central station Send cached data to the site. Through the present invention, it is realized to flexibly and dynamically adjust the access level of competing for wireless channel usage when a station sends a wireless frame for informing a central station to send buffered data to the station.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for sending wireless frames. Background technique [0002] Currently, in the wireless network field, a wireless local area network (WLAN for short) develops rapidly, and demands for WLAN applications are increasing day by day. In the 802.11 group of the Institute for Electrical and Electronic Engineers (IEEE) industry specification, a series of standard WLAN technologies such as 802.11a, 802.11b, and 802.11g have been defined successively, and other tasks have emerged one after another. The 802.11ah task group is committed to the development of specifications related to the improvement of existing 802.11 technologies. For example, the 802.11ah task group is mainly aimed at utilizing the resources of the license-free frequency band below the 1GHz frequency band to support new networks such as smart grids, sensor networks, and cellular network load sharing. a...
