Abstract

A method to transmit and receive a paging message in a wireless communication system is provided. In a method to transmit a paging message, a Base Station transmits a paging message including identifier and location information of a UE to be paged to the UE and receives a paging response message from the UE in response to the paging message. In a method to receive a paging message, the UE switches from a dedicated frequency band for a specific service to a non-dedicated frequency band during a predetermined period or paging gap and checks whether or not a paging message has been received from the Base Station over the non-dedicated frequency band.

Claims

1. A method to transmit a paging message to a User Equipment (UE) in a wireless communication system, the UE receiving a service of a dedicated frequency band, the method comprising:

a Base Station transmitting a paging message including identifier and location information of a UE to be paged to the UE; and

receiving a paging response message from the UE in response to the paging message.

2. The method according to claim 1, wherein the location information includes information of one of a plurality of tracking areas included in a cell of the dedicated frequency band.

3. The method according to claim 1, wherein transmitting the paging message to the UE includes transmitting the paging message to the UE in a different paging interval according to the location information.

4. A method to transmit a paging message to a User Equipment (UE) in a wireless communication system, the UE receiving a service of a dedicated frequency band, the method comprising:

a Base Station transmitting data of the service of the dedicated frequency band to a UE having information of a paging gap; and

suspending transmitting the data during an interval of the paging gap and transmitting a paging message to the UE.

5. The method according to claim 4, wherein the information of the paging gap is transmitted to the UE through one of an MCCH or an MSCH.

6. A method of a User Equipment (UE) to receive a paging message in a wireless communication system, the UE receiving a service of a dedicated frequency band, the method comprising:

the UE receiving a paging message including identifier and location information of the UE from a Base Station; and

transmitting a paging response message to the Base Station if the location information included in the paging message is identical to registered location information.

7. The method according to claim 6, further comprising checking system information of the dedicated frequency band and registering location information of the UE if a location area included in the cell does not include the registered location information.

8. A method of a User Equipment (UE) to receive a paging message in a wireless communication system, the UE receiving a service of a dedicated frequency band, the method comprising:

the UE switching from a dedicated frequency band for the service to a non-dedicated frequency band according to a predetermined period; and

checking whether or not a paging message has been received from a Base Station over the non-dedicated frequency band.

9. The method according to claim 8, wherein switching from the dedicated frequency band to the non-dedicated frequency band includes transmitting information of the predetermined period to the Base Station.

10. The method according to claim 8, wherein the predetermined period is information transmitted from the Base Station to the UE.

11. The method according to claim 8, wherein the UE switches from the dedicated frequency band to the non-dedicated frequency band without receiving a BCH.

12. A method of a User Equipment (UE) to receive a paging message in a wireless communication system, the UE receiving a service of a dedicated frequency band, the method comprising:

the UE switching from a dedicated frequency band for the service to a non-dedicated frequency band during an interval of a paging gap; and

checking whether or not a paging message has been received from a Base Station over the non-dedicated frequency band.

13. The method according to claim 12, wherein the paging gap is defined for each MBMS service or each MBMS dedicated layer.
