Embodiment Construction

[0019] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] One of the core concepts of the embodiments of the present invention is to propose a method and device for sending a probe response frame, so as to effectively improve the wireless service quality and user experience when the STA roams. The present invention can be applied to an embodiment in which a STA roams from an AP under the same wireless network to another AP. Specifically, when the STA moves out of the signal coverage of the currently accessed AP, the STA will select an AP according to its own roaming decision. A destination AP, and roaming is completed by accessing the destination AP. In addition, the present invention can also be applied to scenarios such as STA going offline from a certain AP and going online for...

Abstract

The present invention provides a detection response frame sending method and device. The detection response frame sending method includes the following steps that: a detection request frame from a terminal STA is received; when it is determined that the STA should be responded according to the detection request frame, a waiting duration corresponding to a signal intensity is determined according to the signal intensity measured when the detection request frame is received, and a corresponding relation of a preset signal intensity range and the waiting duration, and the larger the average value of all signal intensities in the signal intensity range is, the larger the waiting duration corresponding to the signal intensity range is; and after the waiting duration is determined, a detection response frame is sent to the STA. With the detection response frame sending method and device of the invention adopted, intervention for the delay of the return of detection response information of an AP end can be realized, so that the probability of the access of the STA during roaming to an AP with good wireless service quality can be improved, and wireless service quality during roaming and user experience can be improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for sending a probe response frame. Background technique [0002] In a WLAN (Wireless Local Area Networks, wireless local area network), a terminal (Station, STA) may roam between different access points (Access Point, AP), and it is often determined by the STA itself which AP the STA roams to. [0003] In a wireless roaming implementation scheme, after a STA leaves an AP, it will broadcast a probe request frame; all APs that receive the probe request frame respond, that is, send a probe response frame to the STA; In sequence, select the AP that responds last within the access response period. [0004] However, in the foregoing wireless roaming mode, the terminal may access an AP with poor wireless service, thereby affecting user experience. Contents of the invention [0005] The technical problem to be solved by the embodiments of the prese...
