摘要:
A method of providing a handover service to a mobile communication terminal supporting multi-modal communications, and a mobile communication terminal for performing the method are provided. More particularly, a method of eliminating an interruption of a data transmission service occurring during a handover between different communication networks, and a terminal for performing the method are provided. A method of providing a handover service of a mobile communication terminal supporting multi-modal communications can include: transmitting and receiving data to/from a corresponding node via a first access network and a second access network while simultaneously maintaining an association with the first access network and the second access network, determining a point in time of completing a handover registration, and releasing an association with the first access network after the point in time of completing the handover registration.
摘要:
A control method for a mobile terminal which connects to a router linked to an external network through at least one interface, including receiving a router advertisement message from the router through a first interface, determining whether prefix information of the received router advertisement message is identical with prefix information of a preset internet protocol (IP) configuration reuse group including the first interface, and generating an IP configuration of the first interface when the two prefix information are identical. Accordingly, at the time of a vertical handover, continuity of the A/V session can be maintained without having to use mobile IP technology.

A method of configuring and registering an Internet Protocol (IPv6) address in a wireless mobile communication system having a connection-oriented radio link is provided. In an IP configuration method without Duplicate Address Detection (DAD), a Mobile Station (MS) is allocated a unique Connection Identifier (CID) specific to the MS from a serving Base Station (BS), and the MS and BS configure the IPv6 address independently using a known network prefix, a Medium Access Control (MAC) address of the MS, and the allocated CID. The BS registers the configured IPv6 address to a HA on behalf of MS.
摘要:
A handover method of a mobile station (MS) in a mobile communication system having MSs and radio access stations (RASs), each of which includes an IEEE 802.16 standard-based medium access control (MAC) layer and an Internet protocol version 6 (IPv6)-based IP layer. The handover method includes the step of gathering IP network information of a neighbor RAS through a message exchange with a previous RAS. A target RAS for handover based on the gathered IP network information of the neighbor RAS is determined, after the target RAS is determined, the previous RAS tunnels data for targeting the MS to the target RAS, Then the tunneled data are received from the target RAS.
摘要:
A network discovery method in a heterogeneous network environment. The network discovery method includes receiving neighbor information indicating neighbor PoAs from a MIIS entity at a mobile node that includes a plurality of communication interface sections capable of communicating with different networks; checking at least one neighbor PoA using the neighbor information at the mobile node; and activating a communication interface section corresponding to the checked neighbor PoA at the mobile node. Accordingly, the neighbor networks can be discovered under the heterogeneous network environment and unnecessary power consumption can be avoided.

A service handover control apparatus and a method using the apparatus are provided. The service handover control apparatus includes a service handover management unit collecting information associated with a transmitting terminal and a wireless access network, which operate based on an Internet Protocol multimedia subsystem (IMS), and outputting a control signal which controls service handovers of the transmitting terminal and the receiving terminal based on the collected information; and a service handover controller providing the service handover management unit with the information associated with the transmitting terminal and the receiving terminal, and controlling the service handovers of the transmitting terminal and the receiving terminal based on the control signal.
摘要:
A mobility supporting method and a mobility supporting system using the method are provided. The mobility supporting method includes a first access router for allocating a prefix to a mobile terminal, and registering the allocated prefix in an authentication server when the mobile terminal connects to the first access router. There is also the authentication server for verifying the mobile terminal based on the registered prefix, and reporting a result of the verifying of the mobile terminal to a second access router when the mobile terminal moves to connect to the second access router and the second access router for notifying the reported result of the verifying the mobile terminal to the first access router.

摘要:
A mobile terminal and method of notifying an access router of an Internet protocol (IP) address of the mobile terminal in a wireless network are provided where a mobile terminal notifies an access router of an IP address of the mobile terminal, performing duplicate address detection (DAD) with respect to an automatically-configured IP address are performed, and a notification message including the IP address resulting from the performing of the DAD are transmitted to the access router. The access router is notified by using the notification message. The mobile terminal uses the IP address, based on whether there is a response with respect to the notification message transmitted to the access router after the performing of the DAD.

Disclosed is a method for fast handover in a wireless security data communication environment. The fast handover method for a mobile node connected to a network via an access point to perform a data communication in a wireless communication environment according to the present invention includes: performing an authentication while communicating with an authentication server having registration information about the mobile node via an uncontrolled port of the access point so as to make the mobile node connected to the network; performing a mobile Internet Protocol (IP) registration for binding a Care-of-Address (CoA) to a home agent and a correspondent node (CN) via the access point in parallel with performing the authentication; and opening a control port of the access point and relaying data transceived at the mobile node using the CoA when the authentication and the registration being successfully completed. Accordingly, a fast handover of the mobile node can be supported.
