摘要：
A method and apparatus may be used to cancel a communication session. The apparatus may transmit a first message to initiate a communication session and then transmit a second message that indicates a request to cancel the communication session. If the apparatus determines that there is an ongoing Packet Switched (PS) session, the apparatus may continue the ongoing PS session on a current Radio Access Technology (RAT) without performing an intersystem change. If the apparatus receives a handover (HO) command, the apparatus may transmit a message to reject the HO command, or it may ignore the HO command.
