US 9,794,966 B2 · Identifier assignment method and device in wireless local area network

Abstract

The disclosure discloses an identifier assignment method in a Wireless Local Area Network (WLAN), which includes: a group identifier is set for a non-Access Point Station (STA). The method further includes: in a process during which the STA associates or reassociates to an Access Point (AP), a terminal identifier is assigned to the associated or reassociated STA or a terminal identifier and a group identifier are assigned to the associated or reassociated STA. The disclosure also discloses an identifier assignment device in a WLAN for implementing the terminal access method. The terminal identifier is significantly expanded through the setting of the group identifier, so that a unique identifier can be assigned to the STA accessing to the AP without identifier repetition of the STA. Meanwhile, the grouping of the STA also facilitates the scheduling and management of the STA in a group. The disclosure ensures that sufficient STAs can access to the AP and a different identifier can be assigned to each STA.

Dependent claims

An identifier assignment method in a wireless local area network, wherein the method comprises:

in a process during which a non-Access Point Station (STA) associates or reassociates to an Access Point (AP), assigning a terminal identifier and a group identifier to the associated or reassociated STA, the group identifier being assigned via an association response frame or a reassociation response frame from the AP,
wherein the assigning a terminal identifier and a group identifier to the associated or reassociated STA comprises:
sending, by the STA, an association request frame or a reassociation request frame to the AP, wherein the association request frame or the reassociation request frame includes at least one of followings:
application category information of the STA, power saving capability information of the STA, operator's identifier information of the STA, manufacturer's identifier information of the STA and physical location information of the STA;
and
returning, by the AP, the association response frame or the reassociation response frame to the STA, wherein the association response frame or the reassociation response frame includes the terminal identifier and the group identifier assigned by the AP to the STA.

An identifier assignment device in a wireless local area network, comprising an assignment unit, wherein

the assignment unit, located in an Access Point (AP), is configured to, in a process during which a non-Access Point Station (STA) associates or reassociates to the AP, assign a terminal identifier and a group identifier to the associated or reassociated STA, the group identifier being assigned via an association response frame or a reassociation response frame from the AP,
wherein the device further comprises a sending unit configured to return the association response frame or the reassociation response frame to the STA when the STA sends an association request frame or a reassociation request frame to the AP,
wherein the association request frame or the reassociation request frame includes at least one of followings:
application category information of the STA, power saving capability information of the STA, operator's identifier information of the STA, manufacturer's identifier information of the STA and physical location information of the STA;
and
the association response frame or the reassociation response frame includes the terminal identifier and the group identifier assigned by the AP to the STA.
