摘要:
A method of providing discovery information of an Electronic Service Guide (ESG) bootstrap entry point is provided. The method includes listing at least one piece of ESG bootstrap characteristic information for an ESG bootstrap proper for a status of a terminal, creating a Management Object (MO), which connects the ESG bootstrap entry point with said at least one piece of ESG bootstrap characteristic information and transmitting the created MO to the terminal through an interactive channel.
摘要:
A method and apparatus for sending a broadcast service in a digital broadcasting system. The method includes assigning a same Internet Protocol (IP) address for a common broadcast service when the common broadcast service is provided in at least two IP platforms, each of the at least two IP platforms providing a broadcast service to a terminal; delivering the common broadcast service using the same IP address; and delivering related information relevant to the common broadcast service.

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.

Disclosed is a DVB-H CBMS system by which a user can continue to view a program being in service even when the transport stream or IP platform changes while the user views the program. In the DVB-H CBMS system, the system transmits service mapping information according to transport streams or IP platforms to the terminal, so that the system can provide a service without interruption to the terminal even when a user of the terminal moves out of a current cell or network into a new cell or network while receiving a service that the user selected.
摘要:
A method and apparatus for supporting mobility in a mobile broadcasting system in which Electronic Service Guide (ESG) discovery is required. The mobility support is classified into three ways according to three different aspects. The first way is to provide roaming information for a local IPDC operator having a roaming partner among local IPDC operators. In the second way, a terminal transmits a query message for requesting transmission of information on a particular local IPDC operator, and receives information on the particular local IPDC operator in response thereto. The third way is to provide the terminal with type information of an ESG; an access type of which is classified according to provision of a roaming service. The roaming information, the information on the particular local IPDC operator and the type information of the ESG, which are provided to the terminal from the mobile broadcasting system, can be provided in an ESG bootstrap level.
摘要:
A system and method for transmitting broadcast service data in a digital broadcasting system. The method includes setting a flag indicating a service area representative of coverage where broadcast service data is provided, for each broadcast service; and transmitting broadcast service information including the flag and a Transport Stream (TS) including the broadcast service data.
摘要:
A method for providing a broadcast service to a terminal by a network in a Digital Video Broadcasting-Handheld (DVB-H) Convergence of Broadcasting and Mobile Service (CBMS) system. The method includes generating Program Specific Information/Service Information (PSI/SI) indicative of information related to a broadcast service requested by the terminal; generating mapping information for information on the broadcast service in an Internet Protocol (IP) platform from which the terminal is currently receiving the broadcast service, and for information on a broadcast service corresponding to the broadcast service in IP platforms other than the IP platform; and including the generated mapping information in an IP/Medium Access Control (MAC) Information Notification Table (INT) of the PSI/SI, and delivering the INT to the terminal.
摘要:
An apparatus and method for enabling a terminal to continuously receive an on-going service even when the terminal moves out of a serving cell or a home network in a DVB-H CBMS system are provided, in which a network controls a handover, designates a target cell for the terminal if the terminal is to perform the handover on an interactive channel, and when needed, processes the handover over an interactive network.
摘要:
Disclosed is a method and an apparatus for supporting smooth and seamless handover of a terminal receiving digital broadcasting in a digital broadcasting system. A handover method by a network node includes the steps of receiving a handover proposal message from a terminal, the handover proposal message containing a time for signal quality evaluation, a service ID, and a cell ID, the terminal receiving a broadcasting service from a serving cell; evaluating signal qualities of candidate cells providing a service corresponding to the service ID; calculating a handover candidate parameter based on a result of evaluation of the signal qualities of the candidate cells, the handover candidate parameter indicating time available for handover with regard to respective candidate cells; and transmitting the handover candidate parameter to the terminal.
