The present invention relates to a method and apparatus for performing IPv6 over IPv4 transition to improve performance of a control server. When an edge router selected by the control server according to a tunnel creation request of an IPv6 terminal receives a tunnel creation request message from the control server, the edge router transmits a tunnel creation response message for the received tunnel creation request message to the IPv6 terminal through the control server, and the edge router performs IPv6 over IPv4 transition through a tunnel created by the IPv6 terminal that received the tunnel creation response message so as to improve the performance of the control server. Therefore, loads of the control server occurred because all terminals set control tunnels to the control server can be prevented, and service extensibility due to the increase in the number of subscribers can be guaranteed.

IPv6 over IPv4 transition method and apparatus for improving performance of control server

A traffic control apparatus is provided which includes an interface connector to transmit/receive an Internet Protocol (IP) packet to/from an external circuit, a frame generator to receive the IP packet through the interface connector and to generate a Media Access Control (MAC) frame, and a network processor to transmit/receive the IP packet to/from the frame generator, to execute at least one programmable application, and to identify and classify the at least one programmable application.

Apparatus and method for controlling traffic

Provided is a method for configuring a control tunnel and a direct tunnel in an IPv4 network-based IPv6 service providing system. To provide IPv6 service, when a random request terminal receives a tunnel response message from a control server by using service information downloaded from a portal server at the time of initialization, the request terminal configures a control tunnel with the control server, and is registered to the control server. The request terminal transmits and receives a direct tunnel request message and a direct tunnel response message with a counterpart terminal by using its terminal information learned during the control tunnel configuration, i.e., network position information and status information, thereby configuring a direct tunnel. Thus, IPv6 communication is made through IPv4 based IPv6 tunneling, so that IPv6 application services that are not yet widely used can easily come into wide use. Also, only software change of each terminal and a control server is required without changing existing network equipment, so that a cost burden of a service provider can be minimized.

Method for configuring control tunnel and direct tunnel in IPv4 network-based IPv6 service providing system

Provided are a system and method for interworking Service Capability Features (SCFs) and protocols in an open service gateway. The system includes service capability features that generate and process various protocol messages, and a protocol stack that enables an interwork with a communications network. The protocol stack includes: one or more units that maintain various protocols, a unit that performs data connection and transmits and processes messages, and a unit that manages the various protocols. In the protocol stack, protocol identifiers that differentiate the protocols from one another, and message identifiers that differentiate service capability features from one another are stored in the unit that manages the various protocols.

System and method for interworking SCFs and protocols in open service gateway

Provided are a system and method for providing an electronic business card service using an open service interface. In the system, a business card information register receives electronic business card information from terminals of presentities who provide an electronic business card, and publishes it on an open service gateway, each of the electronic business card information including identification information and status information of each of the terminals and the terminals being connected to a convergence network; a watcher register receiving identification information of a terminal of a watcher who desires to use the electronic business card information and registers it to the open service gateway; and a business card information providing unit obtaining status information of a terminal of a specified presentity from the open service gateway and transmits it together with identification information of the terminal of the specified presentity to the terminal of the watcher, upon a request for electronic business card information of the specified presentity.

System and method for providing electronic business-card service using open service interface

A method for providing personal information which can overcome the duplication and redundancy of personal information and regional limitation, includes building a Computer Telephony Integration (CTI) information database, a personal information database, and a destination information database in a Service Control Point (SCP), to provide the personal information to CTI destination terminals in an intelligent network; transferring, by a Service Exchange Point (SSP), a calling line identification (CLI) and a dialing number (DN) to the SCP when an originating subscriber dials, retrieving a personal information and a destination information from said databases, and transferring the CLI and the retrieved personal information and destination information to the SSP; and providing, by the SSP, the CLI and the personal information to the destination terminals.
