DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a radio communication device capable of answering and recording.

[0002]

2. Description of the Related Art Currently, portable telephones that can be used even while a vehicle is running are commercially available. Furthermore, if the speed is about the same as walking, it is possible to talk, and PHS is cheaper than the mobile phone.
Terminals called (Personal Handy-phone System) are also commercially available.

[0003]

There have been many reports of traffic accidents caused by this portable telephone. Even if the speed is low, it is dangerous to use the PHS terminal while walking.

[0004]

SUMMARY OF THE INVENTION In view of the foregoing, a wireless communication apparatus according to the present invention is a wireless communication apparatus having a telephone call mode for performing a telephone call at the time of an incoming call and an answering machine mode for recording an answering machine at the time of an incoming call. Movement detection means for detecting whether or not the wireless communication device is moving; a storage unit for storing a message of a caller in an answering machine mode; a notifying means for notifying that the message is stored; A control circuit for operating the notifying unit if the message is stored in the storage unit when the mobile unit is not moving in response to the movement detecting unit.

[0006]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a main configuration of a wireless communication device according to the present invention.

[0007] (1) is a receiving circuit, antenna (2)
And receives radio waves from the public base station, the master unit, and other wireless communication devices through the communication unit. A transmission circuit (3) transmits a signal from a channel / speech codec (5), which will be described later, to a public base station, a master unit, and another wireless communication device via an antenna (2). Reference numeral (4) denotes a PLL that changes the transmission and reception frequencies of the receiving circuit (1) and the transmitting circuit (3). (5) is a channel / speech codec in which a channel codec part and a speech codec part are incorporated in one IC. The channel codec unit performs TDMA / TDD (time division multiple access / time division duplex) processing, CRC error detection, QPSK
Performs demodulation of the system. The audio codec compresses audio
Decompress and convert between analog and digital.

[0008] (6) is a speaker, an amplifier circuit (7)
The electric signal of the channel / speech codec (5) amplified in step (1) is converted into speech. (8) is a microphone, which converts a sound into an electric signal. An amplifier circuit (9) amplifies the output of the microphone (8) and outputs it to the channel / voice codec (5).

Reference numeral (10) denotes a control circuit composed of a microprocessor. The ROM (1) stores an operation program.
Each part is controlled based on 1). A RAM (12) stores information necessary for the operation of the control circuit (10), at least a message (13) of answering machine.

An input means (14) has at least a call mode key (15) and an answering machine mode key (16). The call mode key (15) is a key for designating a mode in which a call is made at the time of an incoming call, and the answering machine mode key (16) is a key for designating a mode of making an answering machine at the time of an incoming call. (17) is a liquid crystal display means for displaying a telephone number, whether the current mode is the call mode or the answering machine mode, and the like. (18) is a bell, which outputs a ringing tone upon receiving a call. (19) is a voice generating means for generating a voice for notifying that there is a dial number, an operation procedure, or a message of answering machine.

(20) is a GPS (Global Positioning S)
ystem) receiver for receiving radio waves from at least three GPS satellites launched by the U.S. Department of Defense. This data is calculated by the control circuit (10) to obtain the current position, and this change with time is determined.
Moving can be detected.

The main operation of the control circuit (10) in the above configuration will be described. FIG. 2 is a flowchart showing the operation of the control circuit (10). It is assumed that the wireless communication device of the present invention is mounted on a vehicle.

The control circuit (10) is a GPS receiver (20)
Then, it is determined whether or not the wireless communication device is moving (that is, whether or not the vehicle is driving) based on the data from (1) (S1). If it is moving, it will be in answering machine mode (S2),
Traffic accidents can be prevented. Since the GPS receiver (20) is used as the movement detecting means, it can be used even when walking. If the wireless communication device is not moving in step S1, the communication mode is set (S1).
3).

However, when the communication mode is designated by the communication mode key (15) (Y in S4), the communication mode is set (S2) regardless of the determination of movement based on the GPS receiver (20) (S1). . Similarly, the answering machine mode key (1
If the answering machine mode is designated by 6) (Y in S5), the determination of movement based on the GPS receiver (20) (S5)
1) Regardless, the answering machine is set to the answering machine mode (S3), and a call at the time of an incoming call becomes possible.

[0015] This allows a passenger other than the driver to answer the incoming call while driving. In addition, while the vehicle is stopped, the wireless communication device can be left inside the vehicle in an answering state and the vehicle can be dismounted.

When the vehicle is not moving (N in S1),
When the message (13) of the answering machine is stored in the RAM (12) (Y in S6), the voice generating means (19) is notified that there is an answering machine (S7). This notification may be made only at the moment when the vehicle stops.

Thus, the driver can drive without being distracted by whether or not there is an answering machine.

Incidentally, the movement detecting means is not limited to the GPS receiver. In particular, when a wireless communication device is mounted on a vehicle, a speedometer, a tachometer, rotation of tires, an ignition switch, a hand brake, a wireless communication device, May be used.

[0019]

According to the present invention, the mobile phone automatically enters the answering machine mode while moving,
Since the communication mode is set during the stop, a traffic accident caused by the wireless communication device can be prevented.

If a GPS receiver is used as the movement detecting means, a traffic accident during walking can be prevented.

[0021] Further, since the call mode key and the answering machine mode key are provided, a passenger other than the driver can answer an incoming call while driving, and when the vehicle is stopped, the wireless communication device is placed in the answering machine state. You can get off.

In addition, since it is notified that there is an absence recording while the vehicle is stopped, the driver can drive without worrying about the arrival of the absence recording.
