Abstract
Provided is a User Equipment (UE) in a wireless communication system supporting a Circuit Switched FallBack (CSFB) service. The UE includes a transceiver for transmitting and receiving a signal to/from a first or second communication system that uses a different frequency; a receiver for receiving a signal from the second communication system; and a controller for controlling an operation of receiving signaling information for the CSFB service from the first communication system through the transceiver, and simultaneously measuring channel status of the second communication system using the signal received from the receiver.
Claims22
A User Equipment (UE) in a wireless communication system supporting a Circuit Switched FallBack (CSFB) service, the UE comprising:
- a transceiver configured to transmit and receive a signal between a first communication system or second communication system that uses a different frequency;
- a receiver configured to receive a signal from the second communication system;
- and
- a controller configured to control an operation of receiving signaling information for the CSFB service from the first communication system through the transceiver, and simultaneously measuring channel status of the second communication system using the signal received from the receiver.
A method for performing communication by a User Equipment (UE) that uses a Circuit Switched FallBack (CSFB) service if a voice call of a second communication system occurs in a first communication system providing a data service, comprising:
- if the voice call occurs, starting measurements on channel status of the second communication system using a receiver for receiving a signal from the second communication system;
- and
- sending and receiving messages for the CSFB service with an evolved Node B (eNB) of the first communication system using a transceiver for communication with the first communication system while performing the measurements on channel status.
