摘要:
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.

A method and apparatus for receiving user roaming and service roaming services from a foreign network in a terminal that has moved from a home network to the foreign network in a digital broadcasting system are provided, in which the terminal receives an ESG from a foreign service provider after entering into the foreign network, selects a roaming type between user roaming and service roaming by determining if an intended broadcasting service is provided from the foreign network, referring to the ESG, receives the intended service from the foreign service provider, if the roaming type is the user roaming, and receives the intended service from a home service provider over the foreign network, if the roaming type is the service roaming.

Provided is a broadcasting system based on a network using an Internet protocol (IP). In the broadcasting system, a broadcast transmitter previously transmits first access information including a first network address for transmitting a general notification message and second access information associated with management of the broadcasting system, to a broadcast receiver. If a general notification event occurs, the general notification message is generated and the generated general notification message is transmitted to the broadcast receiver via one of a broadcast network and an interaction network using the first network address. The broadcast receiver receives a general notification message based on the first network address in data received from the broadcast transmitter.

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.

Disclosed is a method for transmitting a notification message in a mobile broadcast system that includes transmitting common notification message channel information necessary for receiving a common notification message for all users capable of receiving broadcast services, along with an Electronic Service Guide (ESG) for the broadcast services or a control signal for the broadcast services; transmitting specific notification message channel information necessary for receiving a specific notification message for a specific user group to a terminal in the specific user group along with the ESG; generating at least one of the common notification message and the specific notification message; and transmitting the generated notification message to the terminal using the corresponding channel information.
摘要:
A method and apparatus for providing a preview service using an ESG in a digital broadcasting system are provided. Metadata of ongoing broadcasting services are collected. In the presence of preview data for the preview service among the collected metadata, information associated with the preview service is set in a Related Material element included in at least one of a service fragment, a content fragment, and a service bundle fragment in an ESG data model and representing referenced media data. ESG data including the fragments are generated and sent to a terminal.

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.
