Abstract

In a multiservice wireless communication system according to the present invention, a location manager 47 of a multiservice terminal 140 detects its own position with a GPS receiver interface 49. The location manager sends the detected positional information to a management server 110 via a common-signaling wireless network base station 100 in which respective multiple service zones serviced by multiple wireless systems overlap in a common-signaling wireless zone and acquires information on available wireless systems as a response to that. A network selecting section 44 selects a wireless system that most matches selecting conditions from the acquired available wireless systems and performs communication via the interfaces 40 and 41 that operate the selected wireless system.

Claims

1. A multiservice wireless communication system comprising:

a plurality of wireless systems;

a common-signaling wireless network base station in which a plurality of service zones serviced by the wireless systems overlaps in a common-signaling wireless zone;

a management server that stores information on respective available wireless systems in positions in the common-signaling wireless zone as database;

a network connecting them; and

a multiservice terminal serviced therefrom, characterized in that;

the multiservice terminal comprises;

a position detecting section for detecting its own position;

an available-wireless-system-information acquisition section that transmits the position detected by the position detecting section to the management server via the common-signaling wireless network base station and acquires information on available wireless systems in the transmitted position from the management server via the common-signaling wireless network base station; and

a network selection switching section for selecting a wireless system that most matches selecting conditions from the available wireless systems acquired by the available-wireless-system-information acquisition section.

2. A multiservice wireless communication system according to claim 1, wherein

the wireless-system selecting conditions of the network selection switching section include the condition that the wireless system is selected only from wireless systems with low power consumption which match the remaining life of a battery mounted to the multiservice terminal.

3. A multiservice wireless communication system according to claim 1, wherein

the available-wireless-system-information acquisition section displays a list of the acquired available wireless systems on a display for a user to designate a desired wireless system;

and the network selection switching section determines as to whether or not the designated wireless system matches the selecting conditions, wherein when the designated wireless system matches the selecting conditions, the wireless system is selected.

4. A multiservice wireless communication system according to claim 2, wherein

the available-wireless-system-information acquisition section displays a list of the acquired available wireless systems on a display for a user to designate a desired wireless system;

and the network selection switching section determines as to whether or not the designated wireless system matches the selecting conditions, wherein when the designated wireless system matches the selecting conditions, the wireless system is selected.
