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.
