Paging apparatus and method in a mobile communication system providing multimedia broadcast multicast service
First Claim
1. A method of paging a UE (User Equipment) while a second service is in progress at a Node B in a mobile communication system including the Node B and a plurality of UEs within a cell area of the Node B, the Node B providing a first service through a primary carrier, transmitting paging indication information through the primary carrier, transmitting paging information through the primary carrier, and providing the second service to at least one of the UEs through a secondary carrier having a different frequency from the primary carrier, the method comprises periodically transmitting modulated paging indication information to the UE through the secondary carrier.

Abstract
A paging apparatus and method in a mobile communication system providing an MBMS (Multimedia Broadcast Multicast Service). In the mobile communication system, to page a UE for a first service through a primary carrier during a second service in progress through a secondary carrier, a PICH (Paging Indication Channel) transmitter in a Node B transmits paging indication information to the UE through the primary carrier by oscillating the primary carrier as a transmission frequency. A PCH (Paging Channel) transmitter transmits paging information to the UE through the primary carrier or the secondary carrier by oscillating the primary carrier or the secondary carrier as the transmission frequency under a predetermined control. A PBMSCH (Physical Broadcast Multicast Shared Channel) transmitter transmits data of the second service through the secondary carrier by oscillating the secondary carrier as the transmission frequency. A controller controls the primary carrier or the secondary carrier to be oscillated as the transmission frequency of the PCH transmitter if the paging indication information indicates paging.
