A method and apparatus for registering a Media Independent Handover (MIH) is provided. An MIH registration method includes transmitting, by a serving network, an MIH registration request of the serving network to at least one candidate network when an MIH registration request is received from a mobile terminal, the at least one candidate network corresponding to the serving network, receiving, by the serving network, a response to the MIH registration request of the serving network from each of the at least one candidate network, and transmitting, by the serving network, a response to the MIH registration request of the mobile terminal to the mobile terminal.

An apparatus for distributing data traffic in heterogeneous wireless networks is provided. A terminal for transmitting data to a plurality of wireless networks, includes a transmission rule storing unit to store a data transmission rule with respect to the plurality of wireless networks, a data dividing unit to divide first data into a plurality of first data groups based on the stored data transmission rule, a transmission network selecting unit to select an individual transmission network for each divided data group from the plurality of wireless networks based on the determined data transmission rule, and a network access unit to transmit each data group to the selected transmission network.

Apparatus for distributing data traffic in heterogeneous wireless networks

A method of transmitting/receiving a frame between a portable terminal and a base station in a wireless broadband Internet network are provided. More particularly, a method of transmitting/receiving frames can include activating a session between the portable terminal and the base station, removing at least one header information field included in an Internet protocol (IP) datagram after activating the session, adding a network header which sets a predetermined transport connection identifier (TCID) to the IP datagram, generating the frame, and transmitting the generated frame via the activated session. Preferably, the frame is generated in any one of the portable terminal and the base station, and transmitted to the other one of the portable terminal and the base station.

Method of and apparatus for transceiving data frame in wireless broadband internet network

An access router including a module buffering first data to be transmitted to a first mobile station, and transmitting the first data to a second access router when the first mobile station moves to the second access router. Methods of processing a handover by the access router during a handover of the mobile station are also described.

A mobile terminal and a network device for providing a handover service are provided. A mobile terminal includes a transmission unit to transmit a request message for handover information to a network device, and a receiving unit to receive a response message including the handover information from the network device, wherein the request message and the response message are transceived by an application layer protocol.

Mobile terminal and network device for providing handover service

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.

A method for ranging in a wireless communication system and a communication apparatus and/or system using the same are provided. A base station (BS) device includes a terminal grouping unit to group terminals associated with the BS device into a plurality of groups, a radio resource assignment unit to allocate a radio resource assigned to the BS device to each of the plurality of groups, a transmission unit to transmit information about a radio resource assigned to a first group of the plurality of groups to a terminal included in the first group, and a receiving unit to receive a ranging signal from the terminal using the radio resource assigned to the first group, wherein the terminal grouping unit assigns the terminal to be included in a second group of the plurality of groups where the ranging signal is not received by the receiving unit.

System for ranging based on partitioned radio resource

A multi-mode terminal (MMT) including a plurality of interfaces which provides access capability to heterogeneous networks respectively to provide quick handover between the heterogeneous networks, is provided. In this instance, when a Binding Update (BU) message is transmitted to a home agent via each of the plurality of interfaces, routers existing in a path to the home agent may update path latency information and path bandwidth information as a Binding Unique Identifier (BID) sub-option extension of Mobile Nodes and Multiple Interfaces in Internet Protocol version 6 (MONAMI6). In this case, the home agent may receive the BU message and select a care-of address (CoA) by referring to path latency information and path bandwidth information, included in the BU message. Also, the home agent may transmit a success binding acknowledgement (BAck) message with respect to the BU message of the selected path.
