Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incoming call control device, and more particularly to an incoming call control device for a mobile station.

[0002]

2. Description of the Related Art Heretofore, as an incoming call method for a mobile device of this type, there are known call methods such as electronic sound, vibration, light emission, and the like. A combination or "single call of vibration only" is set and used.

FIG. 3 is a block diagram of an example of a conventional incoming call control device. A conventional incoming call control device 101 includes a memory 102 for storing information for selecting a desired incoming call circuit from a plurality of incoming call circuits, and a memory 10 for storing the information.
2, a key input unit 103 for writing information to the control unit 2, a control circuit 104 for selecting one of the incoming call circuits according to the contents of the memory 102 when an incoming signal is input, and a selection output signal from the control circuit 104. Switching circuit 10 for connecting any incoming call circuit to control circuit 104
5 and an incoming call circuit 106.

The incoming call circuit 106 includes an electronic sound calling circuit 107 for calling with an electronic sound and a light emitting circuit (for example, using a light emitting diode (LED)) 108 for calling with light.
And a vibrator circuit 109 called by vibration.

In the memory 102, for example, an electronic sound calling circuit 107 is selected from 6:00 am to noon, and a light emitting circuit 108 and an electronic sound calling circuit 107 (volume: high) from noon to 6:00 pm. It is assumed that information has been written in advance so that the vibrator circuit 109 is selected from 6:00 pm to less than 6:00 the next morning.

[0006] When an incoming signal is input from the radio base station to the control circuit 104, the control circuit 104 checks the current time by a built-in clock (not shown). The incoming call circuit corresponding to 1:00 pm is read from the memory 102.

The memory 102 has a light emitting circuit 108 and an electronic sound calling circuit 107 as an incoming call circuit corresponding to 1:00 pm.
(Volume: high) is written. Therefore, the control circuit 1
04 instructs the switching circuit 105 to switch to the combination of the light emitting circuit 108 and the electronic sound calling circuit 107 (volume: high). Upon receiving this command, the switching circuit 105 connects the light emitting circuit 108 and the electronic sound calling circuit 107 to the control circuit 104.

Thus, the control circuit 104 controls the light emitting circuit 1
08 is emitted, and the electronic sound of the electronic sound calling circuit 107 is increased and output.

Note that information can be written and rewritten in the memory 102 via the control circuit 104 by a key input from the key input section 103.

Japanese Patent Laid-Open Publication No. Hei 3-239022 discloses a car telephone terminal device which changes the volume level according to time as an incoming call control device of this kind.

[0011]

However, in the conventional incoming call control device, the incoming call is notified by the currently set calling method irrespective of the surrounding situation at the time of the incoming call. There is a drawback that when a call is received in a place where the ambient noise is large, such as in a train or a busy street, the incoming call cannot be recognized in the set state.

Conversely, when a call is received during a conference or in a quiet place such as a restaurant while the volume is set to the maximum, there is a drawback that the surroundings are inconvenienced.

Further, when the setting of the vibrating call or the light-emitting call is performed, there is a possibility that the incoming call cannot be recognized and the business opportunity is missed in a state where the mobile device is put in a bag.

As described above, it is very troublesome and burdensome for the user to change the setting every time according to the state of the surrounding environment. Further, even if the volume is changed depending on the time, it is very difficult to cope with the surrounding environment that changes every moment in the action of the day.

A technique for changing the volume level of an audio device according to the magnitude of ambient noise is disclosed in Japanese Patent Application Laid-Open No. 56-3551.
Japanese Patent Application Laid-Open No. Hei 5-114880 discloses a technique for outputting digital voice without ambient noise by digitally converting only voice noise.

However, there is no disclosure of a technique for controlling an incoming call according to the level of ambient noise.

An object of the present invention is to provide an incoming call control device capable of obtaining an incoming call suitable for the surrounding environment without requiring any manpower.
