Abstract

A data storing apparatus is connected to a telecommunications apparatus to allow the telecommunications apparatus to download and install software in a reliable manner. The data storing apparatus includes a powering unit that supplies power to the telecommunications apparatus, a data communication unit connected to the telecommunications apparatus to transmit and receive data to and from the telecommunications apparatus, and a data storage that stores the data received at the data communication unit. The data stored in the data storage includes a data item downloaded by the telecommunications apparatus from an information provider via a wireless network.

Claims

1. A data storing apparatus comprising:

a powering unit configured to supply power to a telecommunications apparatus connected to the data storing apparatus;

a data communication unit configured to transmit and receive data to and from the telecommunications apparatus, the data including a first data item downloaded by the telecommunications apparatus from an information provider via a wireless network; and

a data storage configured to store the data received at the data communication unit.

2. The data storing apparatus of claim 1, further comprising:

a cipher processing unit configured to encrypt and decrypt the data; and

a secret information storing unit configured to save an encryption key.

3. The data storing apparatus of claim 2, wherein the secret information storing unit is tamper-resistant.

4. The data storing apparatus of claim 1, further comprising:

a display configured to display information about the data stored in the data storage.

5. The data storing apparatus of claim 1, further comprising:

a capacitor configured to supply power to the powering unit, the data communication unit, and the data storage.

6. The data storing apparatus of claim 1, wherein the data communication unit receives a second data item having been stored in the telecommunications apparatus when the first data item is updated in the telecommunications apparatus, and the data storage stores the second data item until the updating is completed in the telecommunications apparatus.

7. The data storing apparatus of claim 6, wherein the data communication unit transmits the second data item to the telecommunications apparatus when the second data item is required to boot the telecommunications apparatus.

8. A telecommunications apparatus comprising:

a wireless communication unit configured to transmit and receive data via a wireless network to and from an information provider;

a data communication unit connected to an external data storing apparatus to transmit the data to the data storing apparatus and receive the data from the data storing apparatus when required at the telecommunications apparatus; and

a battery cell configured to receive power being supplied from the data storing apparatus.

9. The telecommunications apparatus of claim 8, further comprising:

an integrity measuring unit configured to measure integrity of the telecommunications apparatus, wherein the wireless communication unit transmits a measuring result of the integrity to the information provider via the wireless network.

10. A Data transmission method comprising the steps of:

downloading a data item to a telecommunications apparatus from an information provider via a wireless network;

storing the data item in an external data storing apparatus connected to the telecommunications apparatus; and

requesting the data storing apparatus to send the stored data item to the telecommunication apparatus when installing the data item in the telecommunication apparatus.
