Dual-mode mobile terminal and method for handover of packet service call between different communication networks
First Claim
1. A dual-mode mobile terminal for performing a handover for a packet service call between first and second communication networks, the dual-mode mobile terminal comprising:
- a first communication module for receiving packet service data through the first communication network, the first communication module being connected to and capable of communicating with the first communication network; and
a second communication module for communicating with the second communication network and being in a disabled state,wherein the first communication module commands the second communication module to prepare for operation and enter into a low power mode, when a packet service call is requested, and commands the second communication module to initialize for a packet service communication, after receiving a handover message from the first communication network when an event for the handover occurs.

Abstract
A dual-mode mobile terminal and method for performing PS call between different communication networks. In the mobile terminal, a second communication module which communicates with a second communication network, prepares for its operation and enters into a low power mode when it is requested for the PS call through a first communication module communicating with a first communication network. When the mobile terminal moves from the first communication network to the second communication network, the second communication module performs an initialization for the PS call to the second communication network. When the initialization is complete, the second communication module interrupts the PS call through the first communication network and performs a packet service communication through the first communication network.

8. A method of performing a handover of a packet service call between first and second communication networks using a dual-mode mobile terminal including a first communication module for communicating with a first communication network and a second communication module for communicating with a second communication network, the method comprising the steps of:
-
receiving packet service data through the first communication network in the first communication module; commanding, by the first communication module, the second communication module to prepare for an operation and to enter into a low power mode; receiving in the first communication module a handover message from the first communication network, after an event for the handover occurs; and commanding, by the first communication module, the second communication module to initialize for a packet service communication. - View Dependent Claims (9, 10, 11, 12)
