Abstract: A screen position sensing method in a multi display system, a content configuring method, a watermark image generating method for sensing a screen position, a server, and a display terminal are provided. A screen position sensing method in a multi display system performed by a sensing server may include receiving identification information of display terminals from a display server, receiving an image output by each of the display terminals from a camera, and determining a screen position of each of the display terminals based on a watermark included in the image of the display terminals and the received identification information.

Abstract: An apparatus and method for controlling multiple display devices based on space information thereof. The apparatus includes a receiver configured to receive space information of multiple display devices; a controller configured to generate a virtual space and generates a scene by mapping content to a screen of each of the multiple display devices in the virtual space based on the space information; and a transmitter configured to transmit information on the generated scene to each of the multiple display devices.

Abstract: A method and apparatus for supporting a flow-based mobility to a multi-mode terminal equipped with a plurality of wired and wireless network interfaces, and selecting an access network may be provided in the PMIPv6 technology that supports a network-based mobility. Also, a flow-based location registration process and a handover process of the multi-mode terminal may be provided, and a flow-based data transmission process and an access network selecting process for the multi-mode terminal may be provided.

Abstract: Provided is a method and apparatus for providing a multimedia message service based on a Parlay X Web service to easily check the status of a multimedia message which is requested to be transmitted in a multimedia messaging application server. The apparatus activates a delivery status informing function for each application server upon receipt of a delivery status information activation request, receives a process result for the multimedia message requested by the application server from an MMS server, and transmits the delivery status information for the requested multimedia message to the application server, for which the status informing function is activated, through a status informing message in real-time.

Abstract: Provided is a method and system of providing a Video on Demand (VoD) service using contents of multiple bitrates that may provide a content encoded at a different bitrate according to a bandwidth of each access network and thereby prevent quality degradation occurring due to a limit of a bandwidth.

Abstract: The present invention relates to a method of balancing a load and method of setting up a call using the load balancing method in a General Packet Radio Service (GPRS) network, which prevents a load from concentrating on a specific Gateway GPRS Supporting Node (GGSN) in the GPRS network, thus reducing a probability of failure in session establishment due to increased traffic. In the load balancing method, when a Service GPRS Supporting Node (SGSN) connected to a mobile node establishes a session, it selects a GGSN having a smallest number of established sessions among a plurality of GGSNs corresponding to an Access Point Name (APN) included in an Activate PDP Context Request message received from the mobile node and requests the selected GGSN to establish a session, thus solving a problem in which a load concentrates on a specific GGSN.
