Abstract: PURPOSE: A channel allocating system and method thereof are provided to request channel allocation about a plurality of related traffic streams by using one message. CONSTITUTION: A communication unit(120) transceives messages for channel allocation and channel release with a channel response device. A correlation confirmation unit(112) checks correlation of traffic streams which receives channel allocation. The correlation confirmation unit confirms whether the traffic streams are related or not. An allocation requesting unit(114) generates a channel requesting message requesting a channel allocation about related traffic streams. The allocation requesting unit transmits the channel allocation request message to the channel responding device through the communication unit.

Abstract: PURPOSE: A paging method in the wireless telecommunications system is provided to transmit the paging information to the terminal receiving a MBS(Multicast/Broadcast Service) from a base station. CONSTITUTION: A base station confirms whether the terminal receives MBS or not(S510). In case the terminal receives MBS, the base station transmits the paging related information considering MBS to the terminal(S520). The paging related information considering MBS comprises the paging offset information and the paging cycle information. The paging pre-defined option information and the paging cycle information are set so that the frame, in which the MBS burst assignment information, is accord with the frame in which the paging message can be transmitted.

Abstract: PURPOSE: A multicasting and broadcasting service transmission method in a mobile communications system is provided to easily receive MBS(Multicast and Broadcast Service) packet. CONSTITUTION: An MBS defines the scheduling change time interval so that the terminal does not need to receive an MBS MAP. The information of the packet which the terminal tries to receive the MBS MAP in the past does not change during the corresponding time, the terminal receives the corresponding MBS packet although the MBS MAP is not received for the scheduling change time interval. The scheduling change time interval can be dissimilar according to the service species.
