APPARATUS AND METHOD FOR HANDOVER BETWEEN TWO NETWORKS DURING AN ONGOING COMMUNICATION

摘要

A method (500, 600) and apparatus (200) for handover of a communication device (120) between a first network (130) and a second network (140) while the communication device is in an ongoing communication. The communication device can register with the second network (610). The communication device can also enter an ongoing communication via the first network (620). The communication device can send a transfer request to the second network to request a handover of the ongoing communication between the first network and the second network without interrupting the ongoing communication (640).
