Abstract:
An XDM(XML Document Management) system and method for implementing an XDM function by using an XML document position technique is provided to solve a problem of a signaling overhead caused by transmitting or receiving overlapped information such that they can enhance performance of wireless channels and system resources and a request process time. A method for implementing an XDM document management function by using an XML document position technique comprises the following several steps. A user or an XDMC(XML Document Management Client) sends an XCAP(XML Configuration Access Protocol) PUT request message including an XCAP URI of an XML document to be generated to a corresponding XDMS(XML Document Management Server)(30). The XDMS checks that a corresponding XML document is internally stored by using the XCAP URI included in the XCAP PUT request message, retrieves the XML document, checks a storage position in the XCAP PUT request message, and stores the XML document at the corresponding position(32). The XDMS sends a 201 created message to the XDMC for notifying the XDMC that a corresponding XML document is successfully generated(34).
Abstract:
A delegated operation executing system and a method for executing the delegated operation are provided to transmit ID(Identification) information of the delegating client and ID of the delegated client through a request message, if the delegated client requests the corresponding target system for a specific operation. In a delegated operation executing system, a delegated client(210) transmits a request message for requesting the specific operation and including IDs of a delegated client(200) and the delegating client, to a target system(220). A proxy server executes authentication for the delegated client requesting the specific operation, by using the ID of the delegated client included in the request message in receiving the request message and transmits the request message to the target system if the delegated client is authenticated. The target system executes authority authentication for the delegated client by using the ID of the delegating client included in the request message in receiving the request message.
Abstract:
A system and a method for providing a presence service are provided to control publication of an EPA(Event Publication Agent) by the external object including an ESC(Event State Compositor), and solicit a specific state by activating or deactivating the EPA depending on an on-demand. A ruler describes the publication of the EPA by using a publication rule, transfers the publication rule to the EPA, and requests the EPA to synchronize with the publication rule by using an event package. The EPA registers publishable presence information to an SIP(Session Initiation Protocol) registrar, aggregates the publication rules received from the ruler, and publishes the presence information to the ESC according to the aggregated publication rule. If a synchronization request for the publication rule is received, the EPA transfers a corresponding response message to the ruler. The SIP registrar determines to route the publication rule for the target presence information to the corresponding EPA according to media feature tag information registered by the EPA.
Abstract:
A method and apparatus is provided for transmitting information necessary for the generation of a service guide for a mobile broadcast service in a broadcast system supporting the mobile broadcast service. A Content Creation (CC) block transmits a service guide request message including various sources necessary for the generation of a service guide to a Service Guide Application Source (SGAS). The SGAS transmits the service guide request message to a Service Guide Generation (SG-G) unit over a backend interface. The SG-G generates a service guide using various sources included in the service guide request message, and transmits a service guide generation completion message indicating completion of the generation of the service guide to the SGAS.
Abstract:
본 발명은 Mobile IPv6를 제공하는 무선 통신 시스템에서 이동 단말의 정보를 유지하기 위한 시스템 및 방법에 관한 것이다. 본 발명에서는 모바일 아이피 네트워크에서 이동 단말의 액세스 라우터를 변경할 때, 서비스의 연속성을 제공하며, 액세스 라우터가 변경될 때 시스템의 오버헤드를 줄일 수 있는 시스템 및 방법을 제공한다. 이러한 본 발명의 방법은, 모바일 IPv6를 사용하는 이동 단말과 상기 이동 단말로 모바일 IPv6를 제공하기 위한 홈 네트워크와 방문자 네트워크를 가지는 시스템의 인증/권한부여/과금 서버에서 상기 이동 단말의 세션을 설정하기 위한 방법으로서, 상기 인증/권한부여/과금 서버로 상기 서버가 인증할 수 없는 이동 단말의 인증/권한부여 요구(ARR) 메시지가 수신될 시 캐쉬 엔트리에 상기 이동 단말의 정보가 저장되어 있는가를 검사하는 과정과, 상기 검사결과 캐쉬 엔트리에 상기 이동 단말의 정보가 저장되어 있는 경우 상기 이동 단말의 인증/권한부여를 수행하고, 이를 상기 이동 단말로 전달하기 위한 메시지를 생성하여 전송하는 과정을 포함한다.
