| 20080204242 | Apparatus and Method for Preventing Loss of Baggage Using Rfid - Provided is an apparatus and method for preventing air baggage from getting lost using a radio frequency identification (RFID) system. The apparatus for preventing baggage from getting lost, change, or stolen in which a baggage tag storing baggage management information is attached to the baggage and a receipt tag storing the baggage management information is issued to a baggage owner, the apparatus includes: a tag reader reading the receipt tag and the baggage tag in a predetermined area; and a determiner determining whether the tag reader reads the receipt tag including the same baggage management information as the baggage management information of the baggage tag within a predetermined time before and after the tag reader reads the baggage tag. As a result, air baggage is quickly and exactly managed, costs is reduced, and foreign confidence of an airport is increased, thereby preventing baggage from getting lost and exchanged. | 08-28-2008 |
| 20080273499 | Packet Forwarding Method, Path Reconstrucitng Method and State Transition Method For Avoiding Packet Loss During Handover - Provided is a method of packet forwarding over partial mesh network to avoid packet loss during handover. The method includes: based on first trigger information of a layer 2 obtained when a mobile node (MN) moves from a domain of a currently connected first BS to another domain, expecting a second BS of the domain to which the MN moves; if the first BS acquires second trigger information of the layer 2 indicating a disconnection between the first BS and the MN, forwarding packets destined for the MN to the second BS through the links; and if the second BS buffers the packets forwarded from the first BS and third trigger information of the layer 2 indicating a connection between the second BS and the MN, transferring the buffered packets to the MN. | 11-06-2008 |
| 20090219894 | METHOD OF SELECTING TARGET NETWORK FOR HAND-OVER AND METHOD THEREOF - A conventional handover method is performed in units of base stations, so that there is a problem in that a large amount of power for handover is consumed and implementation cost is high. | 09-03-2009 |
