Claim Text:
1. A method of receiving a paging message of a mobile station (MS) in a multicarrier system, the method comprising: transmitting, by the MS to a base station (BS), a deregistration request message including information indicating whether the MS currently receives an enhanced multicast and broadcast service (E-MBS) when the MS transitions to an idle mode; setting a paging carrier to a first carrier where the E-MBS is provided if the information indicates that the MS currently receives the E-MBS; setting a paging carrier to a second carrier corresponding to a deregistration identifier (DID) modulo N if the information indicates that the MS does not currently receive the E-MBS, wherein N is a number of carriers in a paging; and receiving a paging message from the BS via the first carrier or the second carrier according to the set paging carrier, wherein the information indicating whether the MS currently receives the E-MBS includes information for reception of the E-MBS starts or ends, of which the BS is informed, and wherein if the paging carrier is set to the first carrier, when network reentry fails to perform in a predetermined time after the paging message is received from the first carrier, the paging message is re-received from the BS via the second carrier.
