Abstract

A mobile terminal device (101) includes a charger identification information reception unit (103) that receives, from a charger (121) connected to charge a rechargeable battery (102), charger identification information to be used to identify the charger (121), a setting information storage unit (104) that stores setting information associated with the charger identification information, a setting information extraction unit (105) that extracts, from the setting information storage unit (104), the setting information corresponding to the charger identification information received by the charger identification information reception unit (103), and a setting unit (106) that setting, in the mobile terminal device (101), the setting information extracted by the setting information extraction unit (105).

Claims

1. A mobile terminal device connectable to a network, comprising:

a rechargeable battery serving as a power supply of the mobile terminal device;

a charger identification information reception unit configured to receive, from a charger connected to charge said rechargeable battery, charger identification information to be used to identify the charger;

a selling information storage unit configured to store setting information associated with the charger identification information;

a setting information extraction unit configured to extract, from said setting information storage unit, the setting information corresponding to the charger identification information received by said charger identification information reception unit; and

a setting unit configured to set, in the mobile terminal device, the setting information extracted by said setting information extraction unit and store the setting information storage unit, setting information that is set in said mobile terminal device when charger identification information is accepted when setting information corresponding to the charger identification information received by said charger identification information reception unit is not stored in said setting information storage unit, by associating the setting information set in the mobile terminal device with the charger identification information.

2. A mobile terminal device according to claim 1, wherein the setting information is selected from connection setting information for connection to the network and function restriction setting information that restricts a function of the mobile terminal device.

3. A mobile terminal device according to claim 1, wherein the charger identification information is superimposed on a voltage signal supplied from the charger for charging.

4. A mobile terminal device according to claim 1, wherein the charger identification information is received via a signal line different from a power line for charging supplied from the charger.

5. A mobile terminal device according to claim 1, wherein the charger identification information is received from the charger via a wireless medium.

6. A charging system comprising:

a mobile terminal device connectable to a network;

a rechargeable battery serving as a power supply of said mobile terminal device; and

a charger for charging the rechargeable battery,

said mobile terminal device comprising;

a charger identification information reception unit configured to receive, from said charger connected to charge said rechargeable battery, charger identification information to be used to identify said charger;

a setting information storage unit configured to store setting information associated with the charger identification information;

a setting information extraction unit configured to extract, from said setting information storage unit, the setting information corresponding to the charger identification information received by said charger identification information reception unit; and

a setting unit configured to set, in said mobile terminal device, the setting information extracted by said setting information extraction unit and store, in the setting information storage unit, setting information that is set in said mobile terminal device when charger identification information is accepted when setting information corresponding to the charger identification information received by said charger identification information reception unit is not stored in said setting information storage unit, by associating the setting information set in the mobile terminal device with the charger identification information, and

said charger comprising;

a charger identification information sending unit configured to send the charger identification information to be used to identify said charger to said mobile terminal device.
