Maintenance method of directional link and station STA

Abstract

The invention discloses a maintenance method of a directional link and a station STA. The accuracy and the effectiveness on the availability judgment of the direction link by the STA can be improved. The method disclosed by the embodiment of the invention comprises the following steps: a first station STA monitors an information packet, wherein the information packet carries the first identification information, and the first identification information is used for identifying the first directional sending beam used by the second STA in information packet sending; the first STA judges whether the information packet is the information packet sent to the third STA by the second STA, if the information packet is the information packet sent to the third STA by the second STA, the first identification information is acquired; the first STA judges whether the first identification information is matched with the preset second identification information, if the first identification information is matched with the preset second identification information, the first STA determines that the first directional sending beam is matched with the second directional sending beam, and modifies a value of a counter corresponding to the directional link between the first STA and the second STA, wherein the second directional sending beam is the directional sending beam determined by the second STA after the beam training in the directional link, and the second identification information is used for identifying the second directional sending beam.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a method for maintaining a directional link and a station STA. Background technique [0002] With the development of mobile Internet and the popularization of smart terminals, data traffic has grown rapidly. Wireless local area network (English full name: Wireless Local Area Network, English abbreviation: WLAN) has become a mainstream mobile access technology by virtue of the advantages of high speed and low cost. Compared with the low frequency bands where spectrum resources are increasingly scarce, such as 2.4GHz and 5GHz, the 60GHz frequency band has abundant spectrum resources and can easily achieve Gbps service throughput. For example, the Institute of Electrical and Electronics Engineers (English full name: Institute of Electrical and Electronics Engineers, English abbreviation: IEEE) 802.11ad system operating in the 60GHz frequency band has a peak ra...

Problems solved by technology

[0004] The update of the value of the counter in the existing solution depends on the interaction information of STAs using directional links, but when the number of STAs increases, the average chance of each STA using directional links will decrease, thus affecting the value of the corresponding counter update frequency, which in turn affects the accuracy and effectiveness of STAs in judging the availability of directional links
