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.

Claims

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,

wherein the UE reads the primary carrier based on the paging information received through the secondary carrier.

2. The method of claim 1, wherein the first service has a higher priority than the second service.

3. The method of claim 1, wherein the paging information is transmitted to UEs that are receiving the second service.

4. A method of paging a UE (User Equipment) for a first service while a second service, different from the first service, is in progress in a mobile communication system, the method comprising:

providing, to the UE, the first service through a primary carrier;

providing, to the UE, the second service through a secondary carrier having a different frequency from the primary carrier;

transmitting paging indication information, to the UE, for the first service through the secondary carrier while providing the second service through the secondary carrier; and

transmitting paging information associated with the transmitted paging indication information, to the UE, for the first service through the secondary carrier for triggering the UE to receive the first service through the primary carrier in response to the paging information transmitted through the secondary carrier,

wherein the primary carrier is read by the UE based on the paging information transmitted through the secondary carrier.

5. The method of claim 4, wherein the first service has a higher priority than the second service.

6. The method of claim 4, wherein the paging information is transmitted to UEs that are receiving the second service.

7. A method of paging a UE (User Equipment) for a first service while a second service, different from the first service, is in progress in a mobile communication system, the method comprising:

providing, to the UE, the first service through a primary carrier;

providing, to the UE, the second service through a secondary carrier having a different frequency from the primary carrier; and

transmitting paging information, to the UE, for the first service through the secondary carrier while providing the second service through the secondary carrier, in order for the UE to receive the first service through the primary carrier in response to the paging information transmitted through the secondary carrier,

wherein the primary carrier is read by the UE based on the paging information transmitted through the secondary carrier.

8. The method of claim 7, wherein the first service has a higher priority than the second service.

9. The method of claim 7, wherein the paging information is transmitted to UEs that are receiving the second service.

10. 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 information for the first service through the secondary carrier while receiving the second service through the secondary carrier; 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,

wherein the UE reads the primary carrier based on the paging information received through the secondary carrier.

11. The method of claim 10, wherein the first service has a higher priority than the second service.

12. The method of claim 10, wherein the paging information is transmitted to UEs that are receiving the second service.
