20080316973 | Method and Apparatus for Supporting a Handover Using an Interactive Channel in a Dvb-H Cbms System - An apparatus and method for continuously providing a selected service being watched when a user moves out of a cell or network in a Digital Video Broadcasting-Handheld (DVB-H) Convergence of Broadcasting and Mobile Service (CBMS) system. Information required for a handover is provided to a terminal using an interactive channel. The handover for the terminal can be performed using a conventional scheme and an enhanced scheme even when the user moves to a new cell while watching the selected service. As the enhanced handover scheme is provided, the user can receive a seamless service. In a mobile environment, a handover scenario for the terminal can be efficiently provided. | 12-25-2008 |
20090310566 | METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING MOBILITY INFORMATION SUPPORTING HANDOVER AND/OR ROAMING IN DIGITAL BROADCASTNG SYSTEM - Disclosed is a method and an apparatus for transmitting/receiving mobility information to support the handover and roaming in a digital broadcasting system. The transmission method includes the steps of setting mobility information including information elements for indicating at least one handover/roaming type according to whether or not support of an interactive network is available for handover/roaming; inserting the mobility information into at least one of an ESG regarding broadcasting services, a notification message, and an independent signaling message so that the mobility information is transmitted to at least one terminal; and conducting handover or roaming of the terminal according to the mobility information. | 12-17-2009 |
20100211977 | APPARATUS AND METHOD FOR TRANSMITTING PRESENTATION INFORMATION IN A DIGITAL BROADCAST SYSTEM - A method and apparatus is provided for defining and transmitting/receiving a presentation fragment including therein a requirement for a scheme of displaying an Electronic Service Guide (ESG) in a digital broadcast system. The transmission method includes generating a presentation fragment including therein a requirement for terminal presentation; inputting the presentation fragment including therein a requirement for terminal presentation to an ESG data model through encoding; and transmitting the ESG data model to the terminal. The presentation fragment includes ESG's display control information at the terminal. | 08-19-2010 |
20100228844 | APPARATUS AND METHOD FOR CHANGING SUBSCRIPTION STATUS OF SERVICE IN MOBILE COMMUNICATION SYSTEM AND MOBILE COMMUNICATION SYSTEM THEREOF - A method for changing a subscription status of a service in a mobile communication system, and a system thereof. A method is provided for changing a subscription status of a service by a terminal in a mobile communication system. The method includes transmitting a pause request message, in which a pause period of the subscription status is included, to a network entity; receiving, from the network entity, a pause response message including therein a possible pause period for the pause period included in the pause request message, and a trigger for changing validity for a Long-term Key stored in the terminal; and changing validity for the Long-term Key using the trigger for the possible pause period included in the pause response message. | 09-09-2010 |
20100262826 | SYSTEM AND METHOD FOR ACQUIRING TERMINAL BINDING KEY - A first terminal subscribes to at least one service using a service guide in which information necessary for reception of each service is stored, and sends the service guide and an identifier (ID) of the subscribed service to a smartcard. The smartcard stores the service guide and the ID of the subscribed service, and sends the service guide and the ID of the subscribed service to a second terminal through a response message to a request message used for acquiring TBK information, received from the second terminal. The second terminal receives the response message by sending the request message to the smartcard, acquires TBK information corresponding to a service that the second terminal intends to play back, from the service guide depending on the subscribed service's ID included in the response message, and acquires the TBK by performing an authentication process using the TBK information. | 10-14-2010 |
20130130663 | METHOD AND SYSTEM FOR PROVIDING NOTIFICATION MESSAGE IN A MOBILE BROADCAST SYSTEM - A method for providing a notification message in a transmitter of a mobile broadcast system supporting an interaction channel is disclosed. Upon an occurrence of a notification event, a first means generates a notification message, and generates at least one delivery request message including a target address based on subscription information of the corresponding terminal, using the generated notification message. A second means determines a channel over which it will deliver a notification message to the corresponding terminal based on the target address, and delivers the notification message over the determined channel. | 05-23-2013 |
20130219275 | APPARATUS AND METHOD FOR PROVIDING USER INTERFACE SERVICE IN A MULTIMEDIA SYSTEM - An apparatus and method for providing a User Interface (UI) service in a multimedia system are provided. The method includes receiving, from a UI server, a widget composed of a main part for handling display and a sub part for handling input; displaying information output from the main part of the widget; transmitting the sub part of the widget to a UI client device; receiving, from the UI client device, data input in the sub part of the widget; and controlling the main part of the widget according to the input data. | 08-22-2013 |
20140141757 | METHOD AND SYSTEM FOR PROVIDING NOTIFICATION MESSAGE IN A MOBILE BROADCAST SYSTEM - A method for providing a notification message in a transmitter of a mobile broadcast system supporting an interaction channel is disclosed. Upon an occurrence of a notification event, a first means generates a notification message, and generates at least one delivery request message including a target address based on subscription information of the corresponding terminal, using the generated notification message. A second means determines a channel over which it will deliver a notification message to the corresponding terminal based on the target address, and delivers the notification message over the determined channel. | 05-22-2014 |
20140289721 | METHOD AND SYSTEM FOR UPDATING FIRMWARE OF TERMINALS IN A BROADCAST SYSTEM - A method and apparatus for updating firmware of terminals in a mobile broadcast system including a Broadcast Service Distribution/Adaptation fragment (BSDA) and a Broadcast service Subscription Management (BSM) are provided. The method includes transmitting a request for creation of a content fragment, by the BSM, to the BSDA; delivering, by the BSM, a firmware package to the BSDA; broadcasting, by the BSDA, a service guide including the content fragment to at least one terminal; and distributing, by the BSDA, the firmware package to the at least one terminal. | 09-25-2014 |
