Provided is a method of providing an Internet Protocol (IP)-based mobility service, particularly, a method of providing seamless quality of service (QoS) guarantees when an IP-based mobile service is provided. The seamless QoS management method includes: a method of providing seamless QoS guarantees when an Internet Protocol (IP)-based mobility service is provided, including: determining whether a terminal is newly registered in a network connecting unit; and providing QoS information of the newly registered terminal to the network connecting unit. Therefore, a user can successively receive a Service Level Agreement (SLA)-based service for which he or she subscribes, while moving to other places.

Provided is a traffic authentication apparatus using information on a header of a packet for traffic authentication. The apparatus includes a call admission control agent receiving a call admission request from a calling terminal; a network controller determining whether to approve the call admission request received by the call admission control agent and obtaining call information from the call admission request; and a networking unit which, when the networking unit receives traffic from the calling terminal, compares information on the header of a packet of the traffic with the call information received from the network controller and authenticates the traffic.

In an apparatus and method for integrated signal processing for an IP-based wired and wireless convergence network, based on an ID of a second user acquired in response to a service call request from a first user terminal, a unique address corresponding to the ID is acquired. The location address corresponding to the unique address, acquired from the address information of the terminals being stored and managed, i.e., the transport address of the second user terminal, is acquired. An IP connection request is sent to the acquired transport address of the second user terminal and the transport address of the first user terminal, and upon completion of the IP connection, data traffic for the requested service is transferred.

A call control method for an Internet Protocol (IP)-based mobility service is provided. The call control method for ensuring service continuity in a mobile communication service environment, includes: receiving a call signal message including permanent IP addresses and transport IP addresses from a transmitter terminal and a receiver terminal, and acquiring the permanent IP addresses and the transport IP addresses of the transmitter terminal and the receiver terminal; and performing call control between the transmitter terminal and the receiver terminal on the basis of the transport IP addresses and the permanent IP addresses of the transmitter terminal and the receiver terminal. Therefore, by interfacing with an IP multimedia subsystem (IMS) for controlling a Session Initiation Protocol (SIP)-based service, an IP mobility control apparatus for controlling mobility of a terminal when a call is controlled, and a network control apparatus for controlling a network, it is possible to prevent data transmission from being interrupted while the terminal is moving, thereby providing an IP-based seamless, high-quality service.

Provided are a method and system of providing a multimedia service in an information provider (IP) network, wherein the method is performed by a system of providing an IP-based mobile service. The method includes: detecting whether a user, who is being provided with the multimedia service, changed from a first terminal to a second terminal; obtaining characteristic information of the second terminal; and providing the multimedia service after changing the multimedia service according to the obtained characteristic information. When only a terminal changes and an access network does not change, or when only an access network changes and a terminal does not change, a network automatically recognizes characteristics of the terminal and the access network and automatically changes media according to the recognized characteristics. Accordingly, a multimedia service without quality deterioration is received, and moreover, a service that can satisfy characteristics (capacity, size of display, etc.) of a terminal of a user and a corresponding service level agreement (SLA) of the user are provided in various terminal environments.

Provided are an apparatus and method for modeling and analyzing a network simulation for a salable simulation framework (SSF)-based network simulation package. A system logic set is generated and a network simulation modeling suitable for a predetermined network application is formed according to the system logic set. The network simulation modeling is transmitted to a predetermined network simulation package that performs simulation. Statistical information is generated based on the result according to the system logic set. Complicated network simulation modeling errors can be minimized, and remodeling of the network simulation modeling can be reduced.
