Abstract

PURPOSE: To surely notify a specific call device of an ID that is contained in the carrier wave sent from a transmission output part even in a place distant away from a radio receiver by selecting the ID by an ID selection circuit, confirming the matching of codes by a code matching circuit and then actuating a notification device. CONSTITUTION: The extremely weak radio waves that are leaked out of an IF circuit of a portable telephone main body 1 are received by plural antennas of an incoming detection circuit 2. Then the necessary frequency components of the radio waves are detected and amplified (43) through a receiving circuit 42, and an incoming decision circuit decides an analog or digital communication system. When a proper incoming state is decided, a timer circuit 45 starts and a code generation circuit 48 generates a device type code signal of 8 bits. This code signal is multiplied by an ID number that is generated by an ID generation circuit 47. An ID and a code are transmitted as the carrier waves through an antenna 49a of an FM transmitting circuit 49. The radio waves are received by the antenna of a call device 3, and an ID signal is taken out of the radio waves via a high frequency amplifier, a frequency converter and an IF. Then a notification device is actuated after the matching of codes is confirmed.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless communication device such as a mobile phone, and more particularly to a wireless communication device adapted to notify an incoming state of the wireless communication device by a separate calling device.

[0002]

2. Description of the Related Art In recent years, wireless communication devices such as small transceivers and mobile phones have rapidly become widespread as a means of wireless communication. These wireless communication devices allow a user to easily carry them to a place where they move and to easily communicate with other people at the destination. For example, when a mobile phone receives an incoming call signal, a ringing tone is emitted from a built-in speaker to notify the user of the incoming call status.

[0003]

However, in the above-mentioned conventional wireless communication equipment, even if a ringing tone is generated when an incoming call arrives at a mobile phone, for example, a place where the surrounding noise is large or the mobile phone is If you carry the phone in a bag etc., you may not be able to hear the ringtone, and if you ring the ringtone in a train, a theater, a conference hall, etc., it may disturb other people around you. Therefore, there is a problem that the ringing tone cannot be recognized if the volume of the ringing tone is limited.

Therefore, when a mobile phone receives an incoming call, a mobile phone has been developed in which the main body of the mobile phone is vibrated instead of a ringing tone. When purchasing a mobile phone having such a structure. Has a problem that it is extremely inconvenient because the model must be limited from the beginning, and the incoming call status cannot be confirmed unless the mobile phone body is always worn and carried.

Therefore, recently, as a combined device such as a mobile phone, when a mobile phone receives an incoming call signal, a small calling device is used which notifies the incoming call state by vibrating by catching the incoming call signal. However, in this calling device, when there is another mobile phone nearby, it operates in response to the incoming signals of all mobile phones. There was a problem that it was not possible to determine whether the call arrived.

The present invention has been made in view of the above-mentioned problems, and when a wireless communication device receives an incoming signal, this reception state causes annoyance to people in the surroundings even in a place away from the wireless communication device. It is an object of the present invention to provide a wireless communication device that can surely notify only a specific calling device that does not exist.
