HANDOVER APPARATUS AND METHOD IN A HETEROGENEOUS WIRELESS COMMUNICATION SYSTEM |
摘要 |
Provided is a handover method, in which a call manager of a network having a Circuit Switching (CS) network, a Long Term Evolution (LTE) network, and an Internet Protocol Multimedia Subsystem (IMS) network, provides handover, from the LTE network to the CS network, to a terminal that uses one radio channel. The handover method includes upon receiving a request for handover from the terminal via a node of the LTE network, establishing a line to a Mobile Switching Center (MSC) of the CS network; sending, to the call manager, a request for a change in a session to another party's terminal in communication with the terminal, to establish an Internet Protocol (IP) bearer between the call manager and the other party's terminal; and sending a handover command to the terminal during the establishment of an IP bearer, to establish a radio channel to the CS network. |
