Mobile communication terminal and communication control method
First Claim
1. A mobile communication terminal capable of using a plurality of wireless systems, comprising:
- a storage means for storing area identification data identifying each communication area and remote end selection data respectively corresponding to said area identification data for selecting a remote end wireless system among said plurality of wireless systems;
a present position acquisition means for acquiring present position data; and
a remote end determination means for selecting area identification data from said storage means corresponding to present position data acquired by said present position acquisition means and determining a remote end wireless system referring to said remote end selection data corresponding to said selected area identification data.

Abstract
When the user of the mobile communication terminal produces the originating operation while in the idle state with the wireless system C, the control section acquires the input of the user of the mobile communication terminal via the key input section (step 302) and acquires, through the present position acquisition section, area identification data of an area L where it is placed in the idle state (step 304). The control section makes a reference to the table of connection scores held in the storage section and acquires a connection score p for the system A corresponding to the area L (step 306). Next, the control section judges the start of origination to the system A by using the connection score p (step 308).
