Abstract

Disclosed is a multi-mode multi-band mobile communication terminal and a mode switching method thereof wherein a mode switching can be performed between an asynchronous network and a synchronous network by minimizing interruption in communication. According to the switching method of a multi-mode multi-band mobile communication terminal, the power of a signal received from an asynchronous networkor a synchronous network is measured and the measured power of the received signal drives a modem portion, thereby switching the mode of the mobile communication terminal.

Description

Multi-mode multi-band mobile communication terminal and mode switching method thereof technical field The present invention relates to a multi-mode multi-band mobile communication terminal supporting both asynchronous communication network and synchronous communication network, and more specifically, to a multi-mode multi-band mobile communication terminal and a mode switching method thereof, which can minimize communication interruption Mode switch between the asynchronous mobile communication network and the synchronous mobile communication network at the same time. Background technique Mobile communication services have continued to evolve since the first generation (1G) of mobile communication services, which were primarily used for low-quality voice communications, such as analog cellular advanced mobile services that began providing services in the late 1980s Telephone System (hereinafter referred to as "AMPS"). The second generation (2G) mobile communication servic...
