Method and apparatus for selecting cell in wireless communication system

1. A method for selecting, by a user equipment (UE), a cell in a wireless communication system, the method comprising:

receiving a radio resource control (RRC) connection release message including redirection information from a serving cell;

determining whether to ignore the redirection information in the RRC connection release message according to a release cause of an RRC connection release and a user preference between a unicast service and a multimedia broadcast/multicast service (MBMS) service;

ignoring the redirection information in the RRC connection release message if it is determined to ignore the redirection information; and

selecting a cell on a third generation partnership project (3GPP) long-term evolution (LTE) frequency.

2. The method of claim 1 , wherein it is determined to ignore the redirection information if a first frequency indicated by the redirection information is different from a second frequency.

3. The method of claim 2 , wherein the second frequency is not a frequency providing the MBMS service in which the UE is interested.

4. The method of claim 2 , wherein the second frequency is not a frequency used by 3GPP LTE.

5. The method of claim 1 , wherein it is determined to ignore the redirection information if the UE does not inform the serving cell about an MBMS interest of the UE.

6. The method of claim 1 , wherein it is determined to ignore the redirection information if the UE considers the serving cell as a cell not supporting an MBMS interest indication procedure.

7. The method of claim 1 , wherein it is determined to ignore the redirection information if the UE prefers the MBMS service than the unicast service based on the user preference.

8. The method of claim 1 , further comprising receiving, from the service cell, an indicator indicating whether to allow or disallow the UE to ignore the redirection information.

9. A user equipment (UE) in a wireless communication system, the UE comprising:

a radio frequency (RF) unit configured to transmit or receive a radio signal; and

a processor operably coupled to the RF unit,

wherein the processor is configured to:

receive a radio resource control (RRC) connection release message including redirection information from a serving cell;

determine whether to ignore the redirection information in the RRC connection release message according to a release cause of an RRC connection release and a user preference between a unicast service and a multimedia broadcast/multicast service (MBMS) service;

ignore the redirection information in the RRC connection release message if it is determined to ignore the redirection information; and

select a cell on a third generation partnership project (3GPP) long-term evolution (LTE) frequency.

10. The UE of claim 9 , wherein it is determined to ignore the redirection information if a first frequency indicated by the redirection information is different from a second frequency.

11. The UE of claim 9 , wherein it is determined to ignore the redirection information if the UE does not inform the serving cell about an MBMS interest of the UE.

12. The UE of claim 9 , wherein it is determined to ignore the redirection information if the UE considers the serving cell as a cell not supporting an MBMS interest indication procedure.

13. The UE of claim 9 , wherein it is determined to ignore the redirection information if the UE prefers the MBMS service than the unicast service based on the user preference.
