摘要： A method and system for supporting Internet Protocol (IP) mobility of a Mobile Node (MN) in a mobile communication system. In the mobile communication system supporting Mobile IP (MIP) and Session Initiation Protocol (SIP), MIP location registration is performed in a Home Agent (HA) through a first FA (Foreign Agent) of a first foreign network in which the MN is located. When the MN receives a SIP invite message from a Correspondent Node (CN), it sends, to the CN, a SIP response OK message in which a home address of the MN is recorded. The CN sends a packet to the home address of the MN in a state in which a SIP call of the MN is established. The number of signaling messages and a delay time associated with a handover can be reduced, because the CN sends packets only to the home address of the MN regardless of a changed location of the MN.

摘要： A handoff implementing method in a mobile communication system having a planar structure, in which at least two BSCs are connected to at least two BTSs through a RAN. An MT transmits a first Handoff Request message containing its information and information about its anchor BSC to a target BTS when it moves to a handoff zone. Upon receipt of the first Handoff Request message, the target BTS transmits a second Handoff Request message containing the MT information and its information to the anchor BSC. Upon receipt of the second Handoff Request message, the anchor BSC transmits a traffic signal directed to the MT to the target BTS.

摘要： A wireless packet data system efficiently manages a location of a packet call in a radio environment. A mobile station transmits a location registration message to a target BSC when moving to the target BSC adjacent to a source BSC. Upon receipt of the location registration message, the target BSC transmits a location update message for updating a location of the mobile station to a centralized database. Upon receipt of the location update message, the centralized database updates dormant state information for the mobile station to connect the target BSC to the source BSC. The centralized database transmits a location update result message indicating complete update of the dormant state information to the target BSC.

摘要： A method and system for transmitting data between mesh nodes in a mesh network are provided. A mesh node establishes a connection with at least one neighbor mesh node. Upon generation of data to be transmitted to the neighbor mesh node, the mesh node broadcasts a control message destined for the mesh node and reserves data transmission to the neighbor mesh node by competing with at least one legacy STA connected to the neighbor mesh node. When the neighbor mesh node permits the data transmission, the mesh node transmits the data to the neighbor mesh node.

摘要： A TDM (Time Division Multiplexing)-based mobile communication system that switches a service type according to QoS (Quality of Service). The mobile communication system includes a base transceiver system (BTS) and a mobile station (MS) connected to the BTS. The BTS monitors whether a first service provided from the BTS to the MS is satisfied according to whether at least as much data as a predetermined transmission amount is transmitted to the MS. If the first service is dissatisfied, the BTS switches a service to a second service lower in QoS than the first service so that as much data as a transmission amount smaller than the predetermined transmission amount is transmitted to the MS.
