20090080391 | Network interworking system and method for negotiating qos in network interworking system - A 3GPP-WLAN interworking system to which WLAN user equipment is accessed includes a WLAN access network including a WLAN access point, a 3GPP packet-switched service network including terminal equipment, a 3GPP core network connecting the WLAN access network and the 3GPP packet-switched service network, and a packet data gateway relaying the 3GPP core network and the 3GPP packet-switched service network. The WLAN user equipment negotiates a QoS according to a wireless environment with the WLAN access point to generate a WLAN bearer, negotiates a QoS according to a type of user data with the packet data gateway to generate a WLAN 3GPP IP access bearer, and negotiates a QoS according to data process performance of the terminal equipment with the terminal equipment to generate an end-to-end bearer. | 03-26-2009 |
20100265916 | TUNNEL MANAGEMENT METHOD AND APPARATUS FOR REDUCING PACKET LOSSES OF MOBILE NODE IN MOBILE IP ENVIRONMENT - Provided is a method of managing a tunnel to provide mobile node mobility when a mobile node moves from an existing visiting network to a visiting network which supports a mobile IP, the method comprising: (a) a mobile node detecting a movement of the mobile node and configuring a care-of address (CoA) and thereafter transmitting a location registration (Binding Update) message to a home agent; (b) the mobile node creating a second tunnel in the visiting network and setting the second tunnel as a receiving-only tunnel while maintaining a first tunnel which is already used in the existing visiting network; (c) the mobile node receiving a location registration completion (Binding Acknowledgement) message from the home agent; and (d) the mobile node changing the second tunnel to the tunnel capable of transmitting/receiving by modifying a routing table, and canceling the first tunnel. | 10-21-2010 |
20100290431 | METHOD AND SYSTEM FOR FAST HANDOVER BETWEEN DIFFERENT NETWORKS - A method for fast handover between a 3GE network and a WLAN is provided. When a network change event that represents that a received WLAN signal can disappear or be captured is generated based on the WLAN signal, a terminal receives information on a new access router (NAR) to be used after handover from a previous access router (PAR) to which the terminal is currently connected using a network identifier, and all packets transmitted from the terminal to the PAR are buffered in the NAR. The NAR transmits all the buffered packets to the terminal when receiving a fast neighbor advertisement (FNA) message from the terminal to perform fast lossless handover. | 11-18-2010 |
