Problems solved by technology

With the large-scale and rapid development of wireless network-based Internet of Things applications, the number of STAs connected to an AP has increased sharply, which has brought about a shortage of AIDs in traditional APs.
In addition, terminals may be grouped and managed in the Internet of Things, but no reasonable solution has been proposed in the prior art for the terminal identification allocation process when mass terminals are grouped and managed in a wireless local area network

Embodiment 1

[0077] This embodiment is an embodiment of allocating terminal identification information to STAs after the association process.

[0078] Specifically, the STA sends an Association Request frame (Association Request frame) to the AP for association, and after receiving the Association Request frame, the AP sends an Association Response frame (Association Response frame) to the STA, and carries in the Association Response frame as the The site identification information (Asociation ID) assigned by the STA;

[0079] After the association ends, the STA uses the AID to exchange frames with the AP. The STA sends a first layer message to the AP, and in response to the first layer message sent by the STA, the AP sends a second layer message to the STA, or the AP actively sends the second layer message to the STA. The above-mentioned first and second high-level messages refer to messages defined by the media access control layer or network entities above it, and can be transmitted be...

Embodiment 2

[0083] This embodiment is an embodiment of allocating terminal identification information to STAs after the re-association process is completed or during the re-association process.

[0084] Method 1: STA sends a reassociation request frame (Reassociation Request frame) to AP, and after receiving the Reassociation Request frame, AP sends Reassociation Response frame to STA, and the Reassociation Response frame carries an AID allocated for the STA. After the re-association is complete, the STA uses the AID to exchange frames with the AP.

[0085] After the re-association ends, the STA sends a first-layer message to the AP, and in response to the first-layer message sent by the STA, the AP sends a second-layer message to the STA, or the AP actively sends a second-layer message to the STA. The first high-level message includes at least one of the following parameters: STA application category, equipment vendor identification information, STA power saving capability parameters, an...

Abstract

The invention discloses a method for allocating an identifier, specifically: a non-access station sends a first radio frame to an access point; the access point sends a second radio frame to the non-access station, the second radio frame The frame carries the group identification information allocated for the non-access station, or carries the group identification information and new station identification information allocated for the non-access station. When the non-access station sends the reassociation request frame to the access point, the access point may also carry the new group identifier reassigned for the non-access station in the reassociation response frame sent to the non-access station. information and / or new site identification information. The invention also discloses an identification distribution system correspondingly. The invention distinguishes terminals by grouping identification information and site identification information, can avoid the problem of shortage of AIDs, and can provide support for grouping management of terminals.

Description

technical field [0001] The present invention relates to the field of wireless local area network communication, in particular to an identification distribution method and system. Background technique [0002] At present, in the wireless network field, the wireless local area network (WLAN) develops rapidly, and the demand for WLAN coverage is increasing day by day. The IEEE802.11 Working Group of the Institute of Electrical and Electronics Engineers successively defined a series of WLAN technical standards such as 802.11a, 802.11b, and 802.11g, and then other task groups emerged one after another, dedicated to the development of specifications involving the improvement of existing 802.11 technologies For example, the 802.11n task group proposes a high throughput (High throughput, HT for short) requirement, supporting a data rate up to 600 Mbps. As an evolution of 802.11n, the 802.11ac task group further proposed the concept of VHT (Very Highthroughput) to increase the data ...
