Abstract:
The present invention relates to a system for executing an advertisement sale and a method for executing an advertisement sale which can allow advertisers to directly request an advertisement online and participate in an organization process. The system for executing an advertisement sale according to the present invention comprises a user interface device to which an advertisement requested by an advertiser/advertising agency is input and which selects advertising opportunities to expose the advertisement according to organization conditions of the media; and an advertisement sale execution device which provides the advertiser/advertising agency with information about the advertising opportunities according to the organization conditions of the media so that the advertiser/advertising agency can select the advertising opportunities when the requested advertisement is input through the user interface device. Therefore, the advertiser/advertising agency can be directly connected to the media which expose the advertisement online and can perform selections according to advertisement execution, thereby maximizing effects of the advertisement with reduction of advertising expenses.

PURPOSE: A location based advertisement system and method thereof are provided to improve advertisement effects by providing advertisement content related to the content to a broadcast receiver who watches broadcast content. CONSTITUTION: A keyword reception unit(210) receives advertisement keywords and the ID(Identity) of broadcast content. A location information interface unit(220) collects the location information of a broadcast reception terminal which receives the broadcast content. A content searching unit(230) sorts the advertisement content matched with the location information and the advertisement keywords from the advertisement content.

본 발명은 SIP 폰의 사용자 이동성 제공 장치 및 방법에 관한 것이다. 본 발명의 하나의 특징에 따른 SIP 폰의 사용자 이동성 제공 장치는 고정 SIP 식별자에 대해서 SIP 기반 호 서비스를 제공하도록 환경 설정된 SIP 폰에 대해, SIP 폰 에이전트는 상기 SIP 폰으로의 이동 사용자 접근을 식별하고, 상기 접근한 사용자의 SIP 식별자로 SIP 폰의 위치등록을 수행하며, SIP 프록시 서버는 SIP 폰의 위치정보를 관리하고, 이동 사용자가 상기 SIP 폰으로 SIP 기반 호 착신 및 발신 서비스를 제공받을 수 있도록 상기 SIP 폰으로 송수신되는 SIP 메시지의 SIP 식별자를 변환하여 전송한다. 이와 같이 하면, SIP 폰이 유비쿼터스 컴퓨팅 환경에서 사용자의 개입없이 이동성을 가진 임의의 사용자에게 SIP 기반 이동 멀티미디어 서비스를 수행할 수 있게 된다.
Abstract:
PURPOSE: An FA(Foreign Agent) device for supporting a mobile IP(Internet Protocol) service in an asynchronous mobile communication system and a mobile IP service method using the same are provided to support the mobile IP service about an asynchronous mobile communication network and support several new standards. CONSTITUTION: A mobile IP service registration unit(206) performs a signal process for a mobile IP. A GGSN(Gateway GPRS(General Packet Radio Service) Support Node) interface unit(201) is connected to the mobile IP service registration unit(206) and is interfaced to an asynchronous mobile communication network. A diameter protocol processing unit(204) transmits and receives data with an authentication and billing server(132) of a mobile IP network by an authentication protocol. An authentication unit(202) connects to the mobile IP service registration unit(206) and the diameter protocol processing unit(204), and performs an authentication function of an FA unit by the control of the mobile IP service registration unit(206). A billing processing unit(203) connects to the mobile IP service registration unit(206) and the diameter protocol processing unit(204), gathers billing information about a packet which passes an FA(131) by the control of the mobile IP service registration unit(206), and transmits gathered billing information. A packet routing and tunneling control unit(205) designates a routing table about a mobile node(11) and performs a setup/release function of a tunnel by the control of the mobile IP service registration unit(206).
Abstract:
PURPOSE: A method for managing a session in an external agent for supporting a mobile IP address is provided to support IP mobility in even case that a mobile host moves between mobile communication networks different in a radio connection method. CONSTITUTION: If an external agent receives a mobile IP(Internet Protocol) registration request message from a mobile host, the external agent transmits a converted mobile node request message to an authenticating server and a state of a session is converted into a mobile node standby state. A mobile node reply message received from the authenticating server is converted into a mobile IP registration reply message to be transmitted to the mobile host and the state of the session is converted into a mobile IP activation state. The mobile IP registration request message received from the mobile host is analyzed, so that a message according to the analysis is transmitted to the authenticating server or the local agent, and the state of the session is converted. If the mobile host transmits a session release request, a session release request message is generated and transmitted to the authenticating server and the state of the session is converted into a session release standby state. According to a session termination command message received from the authenticating server, the session is released and converted into an idle state.
Abstract:
PURPOSE: An IP(Internet Protocol) tunnel management method for reusing an IP tunnel in a mobile IP service system is provided to remove a generated tunnel when a user does not exists without generating several tunnels having the same path. CONSTITUTION: If a mobile node leaves a network(700), it is searched whether an IP tunnel to be deleted exists using an IP tunnel table(702). If the IP tunnel to be detected does not exist(706), it is processed as an error(710). If the IP tunnel to be deleted exists(706), the usage of a tunnel element is decreased by 1(707). If the decreased usage of the IP tunnel is 0(708), the corresponding IP tunnel is deleted(709).
