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 in network services provided by a plurality of communication service operators through networks, respectively, comprising:

position registering means for registering a position of the portable telephone terminal to connect the portable telephone terminal with one 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 a plurality of communication service operators;

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

based on said recognition number, said control means making each of said functions be effective or ineffective corresponding to said one of networks to be connected.

2. A portable telephone terminal as claimed in claim 1, 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 to connect the portable telephone terminal with one of said networks, wherein said control means thereafter recognizing said recognition number of said one of said networks.

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

4. A portable telephone terminal as claimed in claim 1, when a network is changed in the portable telephone terminal, said control means recognizing a recognition number of a new one of networks, based on said recognition number, said control means making each of said functions be effective or ineffective corresponding to said new one of networks.

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

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

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

when said control section has recognized a recognition number of one of networks to be connected with said portable telephone terminal, said control section, based on said recognition number, making each of said functions be effective or ineffective corresponding to said one of networks to be connected.
