Abstract

An apparatus and method for acquiring a remote name in a Bluetooth system are provided. The method for acquiring a remote name in a Bluetooth system includes performing an inquiry request to adjacent Bluetooth devices; sorting Bluetooth devices found during the inquiry request in order of Received Signal Strength Indication (RSSI); reducing a page timeout during a remote name acquisition; and acquiring a remote name according to the sorted RSSI.

Claims

1. An apparatus for acquiring a remote name in a Bluetooth system, comprising:

a controller for sorting devices receiving an inquiry request according to Received Signal Strength Indication (RSSI), performing a remote name acquisition procedure in order of the sorted RSSI, and reducing a delay time in the remote name acquisition procedure by changing a timeout of a connection procedure;

a baseband processor for changing the timeout of the connection procedure according to an indication of the controller during the remote name acquisition procedure, and for providing information between the controller and an interface module; and

the interface module for transmitting Bluetooth communication information through the baseband processor according to an indication of the controller.

2. The apparatus of claim 1, further comprising a storage for storing information about Bluetooth devices or information necessary for Bluetooth communication in order of RSSI measured using information received from the controller.

3. The apparatus of claim 1, wherein when the remote name acquisition procedure begins, the controller controls the baseband processor reduce a page timeout used in an Asynchronous ConnectionLess (ACL) procedure within a predetermined range, thereby reducing the delay time during the remote name acquisition procedure.

4. The apparatus of claim 1, wherein when the remote name acquisition procedure ends, the controller controls the baseband processor to reset a page timeout used in an ACL procedure to an original value.

5. A method for acquiring a remote name in a Bluetooth system, comprising:

performing an inquiry request to adjacent Bluetooth devices;

sorting Bluetooth devices found during the inquiry request in order of Received Signal Strength Indication (RSSI);

reducing a page timeout during a remote name acquisition; and

acquiring a remote name according to the sorted RSSI.

6. The method of claim 5, further comprising resetting the reduced page timeout to an original value.

7. The method of claim 5, wherein the sorting step comprises stopping receiving a response to the inquiry request.

8. A method for acquiring a remote name in a Bluetooth system, comprising:

sorting adjacent Bluetooth devices according to a received signal strength; and

acquiring a remote name according to the sorted adjacent Bluetooth devices.

9. The method of claim 8, further comprising resetting a page timeout value for searching the adjacent Bluetooth devices.

10. A Bluetooth apparatus for acquiring a remote name, comprising:

means for sorting adjacent Bluetooth devices according to a received signal strength; and

means for acquiring a remote name according to the sorted adjacent Bluetooth devices.

11. The apparatus of claim 10, further comprising means for resetting a page timeout value for searching the adjacent Bluetooth devices.
