Abstract:
A method and apparatus may be used to cancel a communication session. The apparatus may transmit a message that indicates a request to cancel the communication session. The apparatus may continue a Packet Switched (PS) session without performing an intersystem change. If the apparatus receives an intersystem change command, the apparatus may transmit a message to reject the intersystem change command, or it may ignore the intersystem change command.
