AID reassignment method, and apparatus for performing said aid reassignment method
First Claim
1. A method by a terminal for performing an association ID (AID) reassignment request, the method comprising:
- transmitting an association request to an access point;
receiving an association response including a first AID from the access point;
generating, by the terminal to which the first AID has been assigned by the access point with which the terminal is currently associated, a request frame for an AID reassignment request;
transmitting the generated request frame to the access point with which the terminal is currently associated; and
receiving a response frame including information on a second AID from the access point with which the terminal is currently associated,wherein the second AID different from the first AID is used as a new AID of the terminal,wherein the request frame includes first information indicating whether listen interval information is included in the request frame or not,wherein the, request frame further includes second information indicating whether service type information is included in the request frame or not, andwherein the AID reassignment request is performed when at least one of;
a service type of the terminal being changed,a remaining power of the terminal being lowered or being charged to low power mode,a listen interval of the terminal being changed, ora traffic pattern of the terminal being changed.

Abstract
Disclosed are an AID reassignment method capable of optimally operating a wireless LAN system, and an apparatus for performing the AID reassignment method. The method comprises the steps of: generating a reconnection request frame for an AID reassignment request; transmitting the generated reconnection request frame to the currently associated access point; and receiving a reconnection response frame including AID reassignment information from the access point. Thus, the AID of the currently associated terminal can be dynamically reassigned according to a change in the characteristics of the terminal, thus operating a wireless LAN system in an optimum manner.

6. A method by an access point for performing an association ID (AID) reassignment, the method comprising:
-
receiving an association request from a terminal; transmitting an association response including a first AID to the terminal; receiving, from the terminal which is currently associated with the access point and the first AID having been assigned to the terminal by the access point, a request frame for ATP reassignment request; and transmitting a response frame including information on a second AID to the terminal, wherein the second AID different from the first AID is used as a new AID of the terminal, wherein the request frame includes first information indicating whether listen interval information is included in the request frame or not, wherein the request frame further includes second information indicating whether service type information is included in the request frame or not, and wherein the AID reassignment request is performed when at least one of; a service type of the terminal being changed, a remaining power of the terminal being lowered or being charged to low power mode, a listen interval of the terminal being changed, or a traffic pattern of the terminal being changed. - View Dependent Claims (7, 8, 9, 10, 11)

12. A terminal for performing an association ID (AID) reassignment request, the terminal comprising:
-
a transceiver; and a processor, wherein the processor is configured to; transmit an association request to an access point; receive an association response including a first AID from the access point; generate, when the first AID has been assigned to the terminal by the access point with which the terminal is currently associated, a request frame for an AID reassignment request; transmit, using the transceiver, the generated request frame to the access point with which the terminal is currently associated; and receive, using the transceiver, a response frame including information on a second AID from the access point with which the terminal is currently associated, wherein the second AID different from the first AID is used as a new AID of the terminal, wherein the request frame includes first information indicating whether listen interval information is included in the request frame or not, wherein the request frame further includes second information indicating whether service type information is included in the request frame or not, and wherein the AID reassignment request is performed when at least one of; a service type of the terminal being changed, a remaining power of the terminal being lowered or being charged to low power mode, a listen interval of the terminal being changed, or a traffic pattern of the terminal being changed.

13. An access point for performing an association ID (AID) reassignment, the access point comprising:
-
a transceiver; and a processor, wherein the processor is configured to; receive an association request from a terminal; transmit an association response including a first AID to the terminal; receive, using the transceiver, from the terminal which is currently associated with the access point and the first AID having been assigned to the terminal by the access point, a request frame for AID reassignment request; and transmit, using the transceiver, a response frame including information on a second AID to the terminal, wherein the second AID different from the first AID is used as a new AID of the terminal, wherein the request frame further includes second information indicating whether service type information is included in the request frame or not, wherein the request frame further includes second information indicating whether service type information is included in the request frame or not, and wherein the AID reassignment request is performed when at least one of; a service type of the terminal being changed, a remaining power of the terminal being lowered or being charged to low power mode, a listen interval of the terminal being changed, or a traffic pattern of the terminal being changed.
