Abstract

In a portable telephone terminal for use in network services provided by a plurality of communication service operators through networks, respectively, the portable telephone terminal is connected with one of the networks by registering a position of the portable telephone terminal and transmits and receives a voice signal or a data signal by a control section, the control section has functions corresponding to the network services between the networks and the portable telephone terminal required by a plurality of communication service operators, the control section recognizes a recognition number of the one of networks to be connected with the portable telephone terminal, and based on the recognition number, the control section makes each of the functions be effective or ineffective corresponding to the one of networks to be connected.

Claims

1. A portable telephone terminal for use to access network services provided by a plurality of communication service operators through networks, comprising:

position registering means for registering a position of the portable telephone terminal to connect the portable telephone terminal with a connecting network of said networks;

control means for transmitting and receiving a voice signal or a data signal, said control means having functions corresponding to said network services between said networks and said portable telephone terminal required by said plurality of communication service operators;

said control means recognizing a recognition number of the connecting network of said networks to be connected with said portable telephone terminal; and

based on said recognition number, said control means making each of said functions effective or ineffective corresponding to a set of network services of the network services of the connecting network of said networks to be connected.

2. A portable telephone terminal as claimed in claim 1, wherein when a power supply of said portable telephone terminal is ON, at first, said position registering means registering said position of the portable telephone terminal connects the portable telephone terminal with the connecting network of said networks, said control means thereafter recognizes said recognition number of said connecting network of said networks.

3. A portable telephone terminal as claimed in claim 1, wherein when a power supply of said portable telephone terminal is ON, at first, said control means recognizes said recognition number of the connecting network of said networks, said position registering means thereafter registers said position of the portable telephone terminal to connect the portable telephone terminal with said connecting network of said networks.

4. A portable telephone terminal as claimed in claim 1, wherein when a network is changed in the portable telephone terminal, said control means recognizes a recognition number of another network of networks, based on said recognition number, said control means making each of said functions be effective or ineffective corresponding to a second set of network services of the network services of the other network of the networks.

5. A portable telephone terminal as claimed in claim 1, wherein when said control means cannot recognize a recognition number of one of networks to be connected, said control means makes each of said functions be effective or ineffective corresponding to the set of network services of the connecting network of the networks to be connected in accordance with an operation by a user of said portable telephone terminal.

6. A method of customizing a portable telephone terminal for use to access network services provided by a plurality of communication service operators through networks, said method comprising:

previously preparing in a control section of the portable telephone terminal functions corresponding to said network services between said networks and said portable telephone terminal required by said plurality of communication service operators; and

when said control section recognizes a recognition number of a connecting network of said networks to be connected with said portable telephone terminal, said control section, based on said recognition number, sets each of said functions as effective or ineffective corresponding to a set of network services of said network services of said connecting network of the networks to be connected.
