摘要： Disclosed is a system and a method for offering a broadcast service in a wireless communication system. A mobile telecommunication system for providing broadcast-multicast services includes a serving access network system for transmitting broadcast traffic and an overhead message including information relating to broadcast for at least a neighboring access network system; a neighboring access network system for receiving a transmission request for the broadcast traffic from the serving access network system and transmitting the broadcast traffic; and an access terminal for receiving the broadcast traffic from the serving access network system and the neighboring access network system.

摘要： A synchronization apparatus and method in a mobile communication system. The apparatus and method include measuring transmission delay time by a Packet Control Function (PCF) or an Access Network Controller (ANC) by exchanging packets with each ANTS, and selecting via the PCF or the ANC the longest transmission delay time of the measured time as an initial wireless transmission time, transmitting by the PCF or the ANC the wireless transmission time of the packet to said each ANTS together with packets, calculating a packet waiting time, which is a difference between the time at which said each ANTS has received the packets and the time at which the corresponding packets has been actually transmitted wirelessly, and reporting the calculated packet waiting time to the PCF or the ANC, and updating via the PCF or the ANC the wireless transmission time of next packets by means of information for the packet waiting time from each ANTS, and transmitting via the PCF or the ANC the updated wireless transmission time to the ANTSs.
