Description of the Related Art A mobile phone performs an incoming call operation irrespective of the state of a driving operator when an automobile having a telephone body is located in a service area. If a call is made during driving, there is a possibility that attention during driving may be hindered. Therefore, peripheral devices such as hands-free devices that can communicate without holding a mobile phone are commercially available.

[0003]

However, when an incoming call is received unexpectedly, the operator during driving is not always in a state in which peripheral devices such as hands-free can be used immediately.
Even if such a peripheral device is used, it is desirable not to make a call if there is an incoming call during high-speed driving or the like.

[0004] In view of the above, the present invention provides a method for receiving an incoming call during high-speed movement when carrying a wireless communication device.
An object of the present invention is to provide a portable wireless device that automatically answers a call instead of a call.

[0005]

In order to achieve the above object, a portable wireless device of the present invention detects a moving speed of a wireless device in a portable wireless device communicating with a wireless base station. Moving speed detecting means for selecting a normal incoming call mode when the moving speed detected by the moving speed detecting means is equal to or lower than a predetermined value, and selecting an automatic incoming call answering mode when the moving speed is equal to or higher than a predetermined value; The first state where the machine body is mounted on the vehicle and the second state where the body is not mounted on the vehicle

In the portable wireless device according to the present invention, for example, when a moving speed of a wireless device main body equal to or more than a predetermined value is detected while the vehicle having the wireless device is running, the mode is switched to an automatic incoming call answering mode. It is possible to avoid a problem that an operator during driving is disturbed during driving, and after use, automatically switches from the first state to the second state under predetermined conditions, thereby preventing forgetting to switch. can do.

Here, the moving speed detecting means includes a counter for measuring the number of fadings of the central value of the received electric field strength,
It is preferable to include a comparison unit that compares the measured number of fadings with a set threshold value, and a determination unit that determines the moving speed of the terminal based on the comparison result by the comparison unit. In this case, since the moving speed of the wireless device main body can be detected by measuring the number of fadings, the speed detection is simplified.

[0008] More preferably, in the automatic call answering mode, a message previously stored in the storage means is transmitted to the sender, and the contents of the call are stored in the storage means. In this case, even if the operator does not talk, the message can be transmitted to the caller, and the message of the caller can be reliably received.

In a preferred embodiment, the apparatus further comprises time setting means for setting a continuation time of the first state, and the forcible switching means performs the switching when the time is equal to or longer than a predetermined time and equal to or longer than the continuation time. is there.
