Abstract: PURPOSE: A base station, a mobile station, a method of transmitting a paging message, and a method of receiving paging message are provided to enable a mobile station of an idle mode to normally receive MBS. CONSTITUTION: An MBS transmit unit(130) transmits at least one MBS(Multicast and Broadcast Service) through at least one MBS carrier waves. A paging transmission time determining unit(155) determines one point of time except for the point of time of transmitting a part among at least one MBS or a total with a paging message transmission time for a mobile station. A paging carrier wave determining unit(165) determines the paging message carrier wave for the mobile station. A paging transmission unit(170) transmits the paging message to the mobile station through a paging message transmission carrier in the paging message transmission point.

Abstract: When zone allocation information of sub-bands is changed, a terminal receives a new MBS configuration message after a lifetime of an MBS configuration message at a time when the changed zone allocation information is received is expired. The terminal applies the changed zone allocation information at the beginning of the first MSI of the new MBS configuration message.

Abstract: PURPOSE: A data transmitting method of a mobile multicast/broadcast service is provided to enable a base station and a terminal to accurately set up an MBS service in a wireless communication system. CONSTITUTION: An MBS(Multicast Broadcast Service) resource index and an MBS map including resource allocation information are transmitted to a terminal. The MBS resource index directs the transmitted resource unit number from the transmission start point of the MBS data burst. The resource indicating the MBS resource index is allocated based on resource allocation information. The MBS data burst is transmitted to the terminal.

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 communication method using carrier switching in a wireless communication system supporting multi carriers is provided to switch different carriers, thereby operating a terminal without data and service delay or interruption. CONSTITUTION: A terminal transmits a switching request message indicating what E-MBS service is desired to base station(S410). The base station transmits a switching response message to a terminal(S420). The switching response message includes information about switching timing among carriers set in a terminal. The terminal switches a carrier from the second carrier to the first carrier by referring to a switching response message. The terminal receives data from the base station through the first carrier after the switching timing(S430).
