Abstract

A method and apparatus are provided for improving the data processing speed through the storage of the record information of an identity module. In the method for improving data processing speed, a request for input/output of at least one predetermined record stored in the identity module from an application is received. Metadata about the requested record of the identity module and the request are transmitted to the identity module. Results corresponding to the request are received from the identity module, and are transmitted to the application.

Claims

1. A method of improving data processing speed through a storage of record information of an identity module, the method comprising:

receiving a request from an application for input or output of at least one record associated with the identity module;

transmitting metadata about the at least one record and the request to the identity module; and

receiving results corresponding to the request from the identity module and transmitting the results to the application.

2. The method according to claim 1, further comprising receiving the metadata about the at least one record from the identity module.

3. The method according to claim 1, wherein the metadata about the at least one record selectively includes i) a location of a file that includes the at least one record, an identifier of the file, a number of records, a length of records, and a size of the file, if the request is for the output, or ii) the location of the file associated with the at least one record, the identifier of the file, the number of stored records, the length of stored records, and the size of the file, if the request is for the input.

4. The method according to claim 1, further comprising converting the request into a command to be transmitted to the identity module.

5. The method according to claim 1, wherein the transmitting the metadata is performed to transmit metadata about at least two records and information about the at least two records to the identity module if the request is a request for the at least two records.

6. The method according to claim 1, wherein the at least one record includes at least one of phone book information, short message information, network roaming information, and information about called phone numbers.

7. The method according to claim 1, wherein the identity module is one of a Subscriber Identity Module (SIM) card, a User Identity Module (UIM) card and a Universal Subscriber Identity Module (USIM) card.

8. An apparatus for improving the data processing speed through a storage of record information of an identity module, the apparatus comprising:

an application communication unit which receives a request from an application for input or output of at least one record associated with the identity module;

a node information search unit which searches for metadata about the at least one record; and

an identity module communication unit which transmits the metadata and the request to the identity module.

9. The apparatus according to claim 8, further comprising a command processing unit which converts the request received by the application communication unit into a command to be transmitted to the identity module.

10. The apparatus according to claim 9, wherein the command processing unit transmits metadata about at least two records and information about the at least two records to the identity module if the request, received by the application communication unit, is a command for the at least two records.

11. The data processing speed improvement apparatus according to claim 8, further comprising a node information unit which stores information about nodes of the identity module.

12. The apparatus according to claim 8, further comprising:

a fast inquiry unit which receives the metadata about the at least one record from the identity module; and

a node information update unit which stores in a node information unit the node information received by the fast inquiry unit.

13. The apparatus according to claim 8, wherein the metadata about the at least one record selectively includes i) a location of a file that includes the at least one record, an identifier of the file, a number of stored records, a length of the stored records, and a size of the file, if the request is for the output, or ii) the location of the file associated with the at least one record, the identifier of the file, the number of stored records, the length of stored records, and the size of the file, if the request is for the input.

14. The apparatus according to claim 8, wherein the at least one record includes at least one of phone book information, short message information, network roaming information, and information about called phone numbers.

15. The apparatus according to claim 8, wherein the identity module is one of a Subscriber Identity Module (SIM) card, a User Identity Module (UIM) card and a Universal Subscriber Identity Module (USIM) card.
