Apparatus and method for providing mobile IPTV service in mobile communication system and broadcasting system

摘要

In a mobile communication system and a broadcasting system, an Advanced Base Station (ABS) periodically broadcasts a buffering data packet of broadcast buffering content in providing a Mobile Internet Protocol TeleVision (Mobile IPTV) service. The broadcast buffering content represents content in which a buffering data packet corresponding to a predetermined buffering capacity is periodically broadcasted, and the buffering data packet represents a data packet that is transmitted to be buffered in advance before the broadcast buffering content is actually provided to Advanced Mobile Stations (AMSs).

1. A method for providing a Mobile Internet Protocol TeleVision (Mobile IPTV) service by an Advanced Base Station (ABS) in a mobile communication system and a broadcasting system, comprising:
periodically broadcasting a buffering data packet of broadcast buffering content; upon receiving a content channel request from an arbitrary Advanced Mobile Station (AMS), determining whether a content channel corresponding to the content channel request is a content channel included in the broadcast buffering content; in response to the content channel corresponding to the content channel request being a content channel included in the broadcast buffering content, transmitting, to the arbitrary AMS, remaining data packets except for the buffering data packet in broadcast buffering content being played in the content channel corresponding to the content channel request; and in response to the content channel corresponding to the content channel request not being a content channel included in the broadcast buffering content, transmitting, to the arbitrary AMS, data packets corresponding to the entire content being played in the content channel corresponding to the content channel request, wherein the broadcast buffering content represents content in which a buffering data packet corresponding to a predetermined buffering capacity is periodically broadcasted, and the buffering data packet represents a data packet that is transmitted to be buffered in advance before the broadcast buffering content is actually provided to AMSs, wherein the periodically broadcasting the buffering data packet comprises: transmitting a control message that includes a resource region in which a content MAP message representing information about a transmission schedule of the buffering data packet is transmitted, and information needed for decoding; and transmitting the buffering data packet in resource regions corresponding to the transmission schedule of the buffering data packet.
