Abstract
Provided is a handover control device and method of a multi-mode mobile communication terminal. The device includes a first processing module; a second processing module connected in its inter-chip path with the first processing module; and an application processor for controlling the first processing module to transmit an IMSI (international mobile subscriber identity) to the second processing module when a traffic handover event from a first mode to a second mode occurs.
Claims9
A device for controlling a traffic handover in a multi-mode mobile communication terminal having a separate processing module for each mode, the device comprising:
- a first processing module;
- a second processing module connected in its inter-chip path with the first processing module;
- and
- an application processor for controlling the first processing module to transmit an international mobile subscriber identity (IMSI) to the second processing module when a traffic handover event from a first mode to a second mode occurs.
A method for controlling a traffic handover in a multi-mode mobile communication terminal having a separate processing module for each mode, the method comprising the steps of:
- when a first processing module is powered on in a boundary area, informing a second processing module of a power on state of the first processing module, and responding to the informing of the power on state by the second processing module;
- receiving, by the first processing module, an international mobile subscriber identity (IMSI) from the second processing module and responding to the received IMSI;
- upon receipt of a handover command from a base station, commanding, by the second processing module, the first processing module to perform the handover;
- and
- performing, by the first processing module, the handover using the previously received IMSI, and informing the second processing module of a handover result.
