Title:
デュアルバンド/デュアルモードを支援する移動通信端末とその制御方法
Document Type and Number:
Japanese Patent JP4567066
Kind Code:
B2
Abstract:
The present invention relates to a dual band/dual mode mobile communication terminal, which can perform stable roaming between synchronous and asynchronous mobile communication networks. The mobile communication terminal of the present invention includes an antenna (410), an asynchronous RF device (420), a synchronous RF device (430), and a common module (440). The antenna (410) transmits/receives radio waves to/from an asynchronous mobile communication network (100) and a synchronous mobile communication network (200). The asynchronous RF device (420) performs asynchronous communication with the asynchronous mobile communication network (100) through the antenna (410). The synchronous RF device (430) performs synchronous communication with the synchronous mobile communication network (200) through the antenna (410). The common module (440) provides common resources at the time of wirelessly communicating with the synchronous and asynchronous mobile communication networks through the synchronous and asynchronous RF devices.
