PAGING APPARATUS AND METHOD IN A MOBILE COMMUNICATION SYSTEM PROVIDING MULTIMEDIA BROADCAST MULTICAST SERVICE
First Claim
1. A method of receiving, at a UE (User Equipment), paging for a first service while a second service, different from the first service, is in progress in a mobile communication system, wherein the first service is provided through a primary carrier and the second service is provided through a secondary carrier, the secondary carrier having a different frequency from the primary carrier, the method comprising:
- receiving, by the UE, paging indication information for the first service through the secondary carrier while receiving the second service through the secondary carrier;
receiving, by the UE, paging information for the first service through the secondary carrier in response to the received paging indication information; and
receiving, by the UE, the first service through the primary carrier by switching a reception frequency of the UE from the secondary carrier to the primary carrier in response to the paging information received 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.
