Definitions

  • the present invention relates to a method for changing an association ID (AID), and more particularly, to an AID change method for changing an existing AID into a new AID in a WLAN system.
  • AID association ID
  • wireless local area network is based on radio frequency technology such as personal digital assistant (PDA), laptop computer, portable multimedia player (PMP), etc. It is a technology that allows a user to access the Internet wirelessly at home, a business, or a specific service area by using a portable terminal.
  • PDA personal digital assistant
  • PMP portable multimedia player
  • the AID reassignment count value may instruct to change the AID of the terminal to a new AID immediately at the time of transmitting the AID reassignment frame.
  • the AID reassignment frame may be transmitted corresponding to the PS-Poll frame received by the access point from the terminal.
  • the present invention it is possible to prevent collisions between AIDs when changing the AIDs for one station or when changing the AIDs for a plurality of stations while all AIDs are in use.
  • FIG. 3 is a block diagram illustrating an embodiment of a component of a TIM included in a beacon.
  • FIG. 10 is a block diagram illustrating an embodiment of an AID reassignment frame.
  • FIG. 7 is a conceptual diagram illustrating an embodiment of a structure of a TIM encoded in block units.
  • the station 1 20 may extract an AID reassignment counter value from the AID reassignment frame (S105). In this case, when the extracted AID reassignment counter value is 0, the station 1 20 may immediately change the existing AID to a new AID (ie, a new AID included in the AID reassignment frame).
  • the AP may transmit a beacon according to the beacon period.
  • Station 2 (STA 2) may wake up from the power saving mode and send the PS-Poll to the access point 10.
  • the access point (AP) may generate the above-mentioned AID reassignment frame (new AID: 2000, AID reassignment counter: 4), and generate the generated AID.
  • the reassignment frame may be sent to station 2 (STA 2).
  • the AID reassignment counter value is set to 4 with 26 decremented.
  • the station 2 (STA 2) receiving the AID reassignment frame may transmit an ACK frame to the access point (AP), and set the AID reassignment counter value (4) included in the AID reassignment frame to an initial value to reset the AID.
  • the allocation counter can be started. That is, station 2 (STA 2) may decrease the AID reassignment counter value by 1 every beacon period (or when the beacon is transmitted).
