DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a PHS (Person
al Handy-phone System (simplified mobile phone), which is particularly concerned with theaters and trains that ring when there is an incoming call, or that would be inconvenient if answered aloud. The present invention relates to a mobile phone system that operates so as not to cause any inconvenience inside the mobile phone.

[0002]

2. Description of the Related Art In recent years, portable telephone terminals such as PHS have rapidly become widespread. For this reason, there has been a problem that a call on a train or the like causes trouble to the surroundings. In addition, when a call is received at a theater or the like, a trouble such as the mobile phone terminal ringing and other inconveniences may be assumed.

In order to prevent such a problem, the user must turn off the power of the portable telephone terminal or set the portable telephone terminal to no sound each time. However, if the power is turned off,
Even if a call is received from another person to this mobile phone terminal, the call is not transmitted to the mobile phone terminal at all, and it cannot be known that the call was made. In addition, it is troublesome for the user to switch to the non-ringing every time in a train or a theater, and if the user forgets to switch the ringing, the ringing due to the incoming call may cause trouble to the surroundings.

[0004] To cope with these problems, there is, for example, a portable telephone terminal system disclosed in Japanese Patent Application Laid-Open No. Hei 10-23112. FIG.
FIG. 11 is a system configuration diagram showing a system configuration of a conventional mobile phone terminal (wireless mobile station) disclosed in Japanese Patent Publication No. -23112, and FIG. 11 shows a configuration of a mobile phone terminal in the mobile phone terminal system. It is a block diagram. A dedicated transmitter 400 for transmitting a ringing prohibition signal indicating a ringing prohibition area is provided in the specific area 200, and the mobile phone 1
Dedicated receiver 11 for receiving the ringing inhibition signal at 00
0 is provided.

Next, the operation will be described. According to the above configuration, when the mobile phone terminal 100 moves into the predetermined ringing prohibited area 200, the dedicated receiver 110 transmits the signal from the dedicated transmitter 400 transmitting the ringing prohibited signal of the area. The received ringing prohibition signal is received. Then, in response to receiving the ringing inhibition signal, the control unit sets the ringing state in which ringing is not performed. In other words, the mobile phone terminal 100 determines whether it is inside the ringing prohibited area or outside the ringing prohibited area based on the presence or absence of the ringing prohibited signal.

When a call is made to the mobile phone terminal 100, the mobile phone terminal 100 notifies the base station 300 of a response that the mobile phone terminal 100 is in the ringing prohibited area. In addition, the display unit indicates that the user is in the ringing prohibited area, and stores call information such as the telephone number of the caller and notifies the user. Thereafter, when the user moves out of the ringing prohibited area, the state automatically returns to the ringing state.

[0007]

However, in the conventional portable telephone system, a dedicated transmitter for transmitting a ringing inhibition signal is provided in the ringing inhibition area in addition to a normal radio base station. Since it is necessary to provide a dedicated receiver for receiving this ringing prohibition signal in the terminal, the equipment cost and maintenance of the dedicated transmitter increase, and the number of parts of the mobile phone terminal itself increases. By
There has been a problem in that it conflicts with the demand for miniaturization, weight reduction, power saving, and price reduction. In addition, there is also a problem that the caller cannot communicate because the mobile phone terminal is in the ringing prohibited area and feels discomfort.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and prevents a call from ringing when a call is received in a public place such as a theater or a train to cause trouble for others. In addition, it aims at realizing this with small size, light weight, power saving and low price. In addition, the receiver (user of the mobile phone terminal) knows that the call has been received,
Further, it is an object of the present invention to prevent inconvenience and improve convenience by making the sender understand the situation of the receiver so as to reduce the discomfort of the sender.

This is the answering machine switching unit. Reference numeral 29 denotes a character message section that detects and stores a message of character information transmitted to the mobile phone terminal 1.

Next, the operation will be described. First, the radio base station 3 and the radio base station 5 generate, for example, a notification signal including specific area information or non-specific area information indicating whether the area covered is a specific area as shown in FIG. And transmitted at regular time intervals. At this time, the radio base station 3 serving the specific area 2 sets the specific area indication bit SB to 1 to generate a signal including the specific area information, and the radio base station 5 serving the normal area 4 other than the specific area 2 , Specific area display bit S
By setting B to 0, a signal including non-specific area information is generated.

The portable telephone terminal 1 waiting for the radio base station 3 receives the notification signal transmitted from the radio base station 3. Then, the specific area information detection unit 21 inside the mobile phone 1 determines whether the area covered by the wireless base station that transmitted the notification signal is the specific area based on the specific area display bit SB included in the received notification signal. Detect whether or not. Here, since the specific area indication bit of the broadcast signal transmitted by the wireless base station 3 is 1, it is detected that the specific area is present.

When the specific area information detecting section 21 detects that the area is a specific area, the call switching section 22 stores the current operation state of the call section 18 in the call state storage section 23 and sets the call state. The operation of the unit 18 is set to a silent operation. The state of operation of the calling unit 18 is, for example, a state of a ringing operation for notifying an incoming call by any of a plurality of types of tones a, b, and c, or a state of a non-ringing operation for notifying an incoming call by vibration, light emission, or the like. is there.

Subsequently, when the mobile phone terminal 1 leaves the specific area 2 and waits for another wireless base station 5 serving the normal area 4, the mobile phone terminal 1 receives The transmitted notification signal is received. Then, the specific area information detection unit 21 inside the mobile phone 1 determines whether the area covered by the wireless base station that transmitted the notification signal is the specific area based on the specific area display bit SB included in the received notification signal. Detect whether or not. Here, since the specific area indication bit of the broadcast signal transmitted from the radio base station 5 is 0, it is detected that the specific area is not present.

When the specific area information detecting section 21 detects that the area is not the specific area, the call switching section 22 changes the operation of the calling section 18 to the state of the silent operation stored in the call state storage section 23. Return to the state before switching.

Therefore, for example, when the user sets the portable telephone terminal 1 to make a call with the tone b, the user carries the portable telephone terminal 1 in a predetermined train or theater. When moving to a specific area 2 such as inside, the specific area is detected from the specific area indication bit SB included in the broadcast signal transmitted from the wireless base station 3 that is in charge of the specific area 2, and the calling is performed with the tone b. The control state of the calling unit 18 set as described above is stored in the calling state storage unit 23. Then, switching is performed so as to perform a call with no ringing operation. Therefore, the operation is automatically switched to the silent operation without any trouble of the user,
Even if there is an incoming call in a specific area, it is possible to notify the incoming call without ringing, thereby preventing other troubles.

After that, when the user leaves the specific area 2 with the portable telephone terminal 1 and enters the normal area 4, the notification signal transmitted from the radio base station 5 in charge of the normal area 4 is transmitted. It is detected from the included specific area display bit SB that the area is not a specific area, and the original state stored in the call state storage unit 23 is returned. Therefore, even when the user moves from the specific area to the normal area again, it is possible to automatically switch to the original state without any trouble of the user.

Next, the operation when a call is received to the portable telephone terminal 1 waiting at the radio base station 3 serving the specific area 2 will be described.

Is activated, and the caller can send a message to the mobile phone terminal 1 by voice. Further, in the mobile phone terminal 1, the contents of the call can be confirmed by listening to the message later. By performing such an operation, even if the user of the mobile phone terminal 1 does not change the setting of the answering machine 25, which is the original purpose,
The answering machine 25 is automatically activated, which not only prevents the surroundings from being disturbed by the ringing tone, but also allows the caller's message to be confirmed without calling back later.
Further, convenience can be improved.

After that, when the portable telephone terminal 1 goes out of the specific area 2 and waits for the radio base station 5 serving the normal area 4, the mobile phone terminal 1 receives the broadcast signal transmitted from the radio base station 5, The specific area information detection unit 21 detects that the area is not a specific area. Then, the message recording switching unit 26 returns the operation of the message recording unit 25 to the original state stored in the message recording state storage unit 27.

As described above, even when the vehicle moves from the special area to the normal area again, it is detected from the specific area indication bit SB included in the broadcast signal transmitted from the radio base station serving the normal area that the area is not the specific area. , Since it is returned to the original state stored in the answering machine state storage unit,
It is possible to automatically switch to the original operation mode of the answering machine function without any trouble of the user.
