20100027508 | FAST HANDOVER METHOD AND SYSTEM USING NETWORK-BASED LOCALIZED MOBILITY MANAGEMENT - The present invention relates to a method in which a mobile node having mobility performs handover in a mobile communication system, and more particularly, to a fast handover method and system using network-based localized mobility Management. According to an exemplary embodiment of the present invention, in a network access process between a mobile node and a base station, the base station sends a message allowing network access to the mobile node and a link-up message to an access router. Then, the access router sends a location registration message, which includes a mobile node identifier, a target base station identifier, a localized mobility anchor identifier, and access permission flag information, to a localized mobility anchor (LMA), and receives an acknowledgement (Ack) message including network prefix information. Accordingly, when a router advertisement (RA) message is sent to the base station, the mobile node performs duplicate address detection (DAD). Accordingly, fast handover is performed to reduce packet loss and delay that occur when the mobile node moves between networks, thereby minimizing the packet loss and delay. | 02-04-2010 |

20110064049 | METHOD OF HANDOVER BETWEEN COMMUNICATION NETWORK AND BROADCAST NETWORK FOR PROVIDING BROADCAST CONTENT, COMMUNICATION NETWORK HANDOVER CONTROLLER, AND BROADCAST NETWORK HANDOVER CONTROLLER - Provided is a method for performing handover between a communication network and a broadcast network by a handover controller of a first network corresponding to either the communication network or the broadcast network. The method for performing handover includes: searching for a second network capable of providing the same broadcast content broadcasted over the first network; performing a handover preparation procedure between the communication network and the broadcast network with a handover controller of the second network; delivering the broadcast content broadcasted over the first network to the handover controller of the second network; and sending a message requesting a terminal to watch, over the second network, the broadcast content broadcasted over the first network. | 03-17-2011 |
20110065430 | METHOD AND APPARATUS FOR PAGING DELEGATION IN HETEROGENEOUS NETWORKS - A method for paging delegation in a gateway of a first network among heterogeneous networks is provided. The gateway of the first network receives a first request message that requests paging delegation of the first network from the terminal, and transmits a second request message that requests paging delegation of the first network to a paging controller of the second network. The gateway receives a first response message including a result value for the paging delegation request from the paging controller, sets paging delegation registration information of the terminal based on the first response message, and transmits a second response message. | 03-17-2011 |
