Benefits of technology

[0011] It is, therefore, an object of the present invention to provide an apparatus and method for removing signal interference during Bluetooth communication in a Bluetooth radio device mounted in a mobile terminal.
[0012] It is another object of the present invention to provide a method for removing signal interference in a Bluetooth radio device mounted in a CDMA mobile terminal.

Problems solved by technology

Meanwhile, in a CDMA (Code Division Multiple Access) mobile terminal mounted with a Bluetooth radio device, a part of a third harmonic component of the CDMA transmission frequency belongs to (or overlaps with) the Bluetooth standard frequency band, thus causing interference during the Bluetooth communication.

Embodiment Construction

[0024] A preferred embodiment of the present invention will be described herein below with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

[0025] Although the invention will be described with reference to a case where a third harmonic component of a part of the CDMA transmission frequency band overlaps with a frequency for the Bluetooth radio communication, causing signal interference, it will be understood by those skilled in the art that the invention can also be applied to a case where a third harmonic component of a transmission frequency band for other communication systems other than the CDMA system overlaps with the frequency for the Bluetooth radio communication, causing the signal interference.

[0026] When the third harmonic component of a part of the CDMA transmission frequency band overlaps with a frequency for the Bluetooth...

Abstract

Disclosed is a method for removing signal interference in a local radio communication device mounted in a mobile terminal. The method comprises receiving information on a channel in use from the mobile terminal in session; determining based on the received channel information whether a harmonic component of a channel frequency used by the mobile terminal belongs to a frequency band used by the local radio communication device; and assigning a channel in a frequency band with none of the harmonic component among the frequency band used by the local radio communication device as a channel of the local radio communication device, when the harmonic component of the channel frequency used by the mobile terminal belongs to the frequency band used by the local radio communication device.

Description

PRIORITY [0001] This application is a divisional of application Ser. No. 10 / 144,176 filed in the United States Patent and Trademark Office on May 13, 2002, and claims priority to an application entitled “Apparatus and Method for Removing Signal Interference in a Local Radio Communication Device Mounted in a Mobile Terminal” filed in the Korean Industrial Property Office on May 11, 2001 and assigned Ser.
