Embodiment Construction

[0064] Next, exemplary embodiments of the present invention will be described in detail by referring to the accompanying drawings.

[0065] first exemplary embodiment

[0066] FIG. 1 is a network block diagram of a multi-mode portable terminal. Area 1 represents the service range of a mobile radio communication network (hereinafter simply referred to as "mobile communication network"), Area 2 represents the service range of an IEEE802.16eWiMAX network (hereinafter simply referred to as "WiMAX"), and the area 3 represents the service area of ​​IEEE802.11 wireless local area network (hereinafter referred to simply as "radio local area network"), and base stations 2, 3, 4 are respectively placed in it. Fig. 1 also shows the multi-mode portable A terminal 5. A base station 3 of WiMAX is controlled by a base station control device 1.

[0067] The areas become wider in the order of "mobile communication network (area 1)>WiMAX (area 2)>wireless LAN (area 3)". On the contrary, the ...

Abstract

To provide a multimode portable terminal capable of variously switching over the mode of a network connection according to various needs such as high-quality and high-speed data communication or inexpensive data communication, and a mode switch-over method. [MEANS FOR SOLVING PROBLEMS] A multimode portable terminal connectable to any one of a plurality of radio communication networks with different standards comprises a mode selecting means (51) for presetting mode selection information by the user input, a network judging means (52) for judging in which area of which radio communication network the multimode portable terminal is present on the basis of whether or not there is a radio communication network unique control signal, and a network selecting means (53) for selecting one of the radio communication networks in whose area the multimode portable terminal is present in the order of priority according to the mode selection information.

Description

technical field [0001] The present invention relates to a multi-mode portable terminal that can be connected to a plurality of radio communication networks of different standards, and also relates to a mode switching method of the multi-mode portable terminal. Background technique [0002] Conventionally, a dual-mode portable terminal using a mobile radio communication network and a radio local area network has been developed. A dual-mode portable terminal communicates outdoors via a mobile radio communication network and indoors via a radio local area network. (in a building or home, such as a hotspot). [0003] Service characteristics regarding each of the mobile radio communication network and the radio local area network are as follows. That is, the mobile radio communication network service is advantageous in that it can cover a wide area, is excellent in moving speed and communication quality, and is most suitable for providing voice services. Its disadvantage is th...
