Abstract

Provided are a method and an apparatus for searching neighboring Bluetooth devices in a portable terminal having a Bluetooth module. In the method, addresses of searched neighboring Bluetooth devices are used to determine whether the searched neighboring Bluetooth devices are newly-searched Bluetooth devices. If the searched neighboring Bluetooth devices are newly-searched neighboring Bluetooth devices, name request signals are transmitted to the newly-searched neighboring Bluetooth devices to acquire names of the newly-searched neighboring Bluetooth devices. Names of the newly-searched neighboring Bluetooth devices are created, and the addresses, names and names of the newly-searched neighboring Bluetooth devices are registered in a Bluetooth management database.

Claims

1. A method for registering a neighboring Bluetooth devices in a portable terminal having a Bluetooth module, the method comprising:

acquiring addresses of searched neighboring Bluetooth devices;

comparing an acquired address with addresses in a Bluetooth management database;

assigning a nickname to a searched neighboring Bluetooth device if a corresponding address is not found in the Bluetooth management database; and

registering the nickname of the searched neighboring Bluetooth device with the acquired address in the Bluetooth management database,

wherein the nickname is generated in the portable terminal.

2. The method of claim 1, further comprising searching the Bluetooth management database to detect nicknames corresponding to address of neighboring Bluetooth device and identifying whether the acquired address matches an address in the Bluetooth management database.

3. The method of claim 1, wherein the nickname includes a name and a searching date of the neighboring Bluetooth device.

4. The method of claim 3, wherein the nickname further includes a serial number to distinguish the searched Bluetooth device if a neighboring Bluetooth device has a matching name and search date.

5. The method of claim 3, further comprising:

acquiring a name of the searched neighboring Bluetooth device if a matching address is not found in the Bluetooth management database; and

registering the nickname of the searched neighboring Bluetooth device with the address and the name of the searched neighboring Bluetooth device in the Bluetooth management database.

6. The method of claim 3, further comprising:

determining, using the acquired addresses, whether the searched neighboring Bluetooth devices are newly-searched Bluetooth devices;

if the searched neighboring Bluetooth devices are newly-searched neighboring Bluetooth devices, transmitting name request signals to the newly-searched neighboring Bluetooth devices and acquiring names of the newly-searched neighboring Bluetooth devices;

assigning nicknames to the newly-searched neighboring Bluetooth devices; and

registering the addresses, names and nicknames of the newly-searched neighboring Bluetooth devices in a Bluetooth management database.

7. The method of claim 6, wherein determining whether the searched neighboring Bluetooth devices are newly-searched neighboring Bluetooth devices comprises the steps of:

comparing the addresses of the searched neighboring Bluetooth devices with addresses stored in the Bluetooth management database; and

if the addresses of the searched neighboring Bluetooth devices do not exist in the Bluetooth management database, recognizing the searched neighboring Bluetooth devices as newly-searched neighboring Bluetooth devices.

8. The method of claim 1, wherein the nickname can be changed by a user of the portable terminal.

9. The method of claim 1, wherein the Bluetooth management database includes addresses, names and nicknames of the neighboring Bluetooth devices.

10. A method for searching for a neighboring Bluetooth device in a portable terminal having a Bluetooth module, the method comprising:

acquiring an address of the neighboring Bluetooth device;

comparing the address with an address in a Bluetooth management database; and

upon a determination that the acquired address matches the address in the Bluetooth management database, identifying, from the Bluetooth management database, a nickname generated in the mobile terminal such that the nickname is identified according to the acquired address.

11. The method of claim 10, wherein the nickname includes a name and a searching date of the neighboring Bluetooth device.

12. The method of claim 10, wherein the nickname can be changed by a user of the portable terminal.

13. The method of claim 10, wherein the Bluetooth management database includes addresses, names and nicknames of the neighboring Bluetooth devices.

14. A portable terminal having a Bluetooth module for registering a neighboring Bluetooth device, comprising:

a memory unit for storing a Bluetooth management database; and

a controller for acquiring addresses of searched neighboring Bluetooth devices, comparing an acquired address with an address in the Bluetooth management database, assigning a nickname of the searched neighboring Bluetooth devices if a corresponding address is not found in the Bluetooth management database; and

registering the nickname of the searched neighboring Bluetooth device with the address of the searched neighboring Bluetooth device in the Bluetooth management database,

wherein the nickname is generated in the portable terminal.

15. The portable terminal of claim 14, wherein the nickname includes a name and a searching date of the neighboring Bluetooth device.

16. The portable terminal of claim 14, wherein the nickname can be changed by a user of the portable terminal.

17. The portable terminal of claim 14, wherein the Bluetooth management database includes the addresses, names and nicknames of the neighboring Bluetooth devices.

18. A portable terminal having a Bluetooth module for searching a neighboring Bluetooth device, comprising:

a memory unit for storing a Bluetooth management database; and

a controller for acquiring an address of a searched neighboring Bluetooth device, comparing an acquired address with an address in a Bluetooth management database, and upon a determination that the acquired address matches the address in the Bluetooth management database, identifying, from the Bluetooth management database, a nickname generated in the mobile terminal such that the nickname is identified according to the acquired address.

19. The portable terminal of claim 18, wherein the nickname includes a name and a searching date of the neighboring Bluetooth device.

20. The portable terminal of claim 18, wherein the nickname can be changed by a user of the portable terminal.

21. The portable terminal of claim 18, wherein the Bluetooth management database includes addresses, names and nicknames of the neighboring Bluetooth devices.
