Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of restricting use of a mobile station according to a zone in a mobile communication system having a radio zone structure, and a base station apparatus and a mobile station apparatus for implementing the method.

In a mobile communication system, each base station broadcasts common control information to all mobile stations in its own radio zone through a specific control channel. Each mobile station in the service area of the mobile communication network can receive and make a call by receiving the notification information from the base station in the radio zone in which it is located, and can receive various mobile communication services. While users enjoy the convenience of mobile communication services, they are also required to refrain from abuse from the viewpoint of public manners and the like. For example, the use of mobile stations is prohibited in places that may interfere with public wireless facilities (airports, etc.) and places where there is a great deal of discomfort to surroundings (such as Shinkansen seats). In addition, in public facilities such as trains, hotel lobbies, concert halls, etc., you should refrain from using mobile stations if it may disturb others around you.

[0003]

2. Description of the Related Art In recent years, the equipment of base stations has been enhanced, and mobile communication services have become available in various places. However, as an adverse effect, a radio wave transmitted from the base station may reach an area where the use of the mobile station is prohibited, and a mobile station in the area may make or receive a call. This is because even if the system is designed so that the radio waves transmitted from the base station do not reach the prohibited area, the radio waves may reach due to interference or the like.

In the conventional mobile communication system, the mobile station which received the broadcast information transmitted by the base station on the control channel was able to receive the service unconditionally (except during regulation). Therefore, the user needs to turn on / off the power of the mobile station by himself / herself regardless of where he / she is.

[0005]

However, it is apt to forget that the user is in a prohibited area or a restricted area of use of the mobile station, or even forget to turn off the power of the mobile station. In addition, it is often seen that people without a public mind are using mobile phones without regard for the inconvenience of people around them. In this way, it is not always effective to eliminate the harmful effects if left only to the user's awareness.

The present invention has been made in view of the above problems, and provides a method for automatically restricting the use of a mobile station according to the area type of a radio zone in which the mobile station is located, and a mobile station apparatus therefor. The purpose is to do.

FIG. 7 shows fixed information 6 held by the mobile station MS.
Is shown. The fixed information 6 is information registered in advance in the mobile station MS, and in this embodiment, the wireless zone type 6
1, a power OFF timer 62, and a perch restriction timer 63 are added as new information. The radio zone type 61 is information indicating the use restriction level (usable, refrained from use, use prohibited) of the mobile station in association with the radio zone type code (3-bit binary number) transmitted from the base station. The power-off timer 62 and the perch limit timer 63 are set with timeout times of these timers in units of seconds. These timer-out times will be described in the following operation example of the mobile station MS.

When the power of the mobile station MS is turned on, the standby operation is started, and the call control function 51 determines the reception level while sequentially switching the perch channels, and within the broadcast information received by the control channel having the maximum reception level. The wireless zone type is extracted from the extended information element. Then, based on the wireless zone type 61 of the fixed information 6, the usage restriction level corresponding to the wireless zone type extracted from the notification information is determined. Hereinafter, an operation example of the mobile station MS according to each usage restriction level will be described.

When it is available When the wireless zone type is “000”, the call control function 51 performs the conventional control. When the wireless zone type is "001", the call control function 51 notifies the state monitoring function 52 of the usage refusal control. Upon receiving this notification, the status monitoring function 52 requests the display operation unit 10 to display the message "Restricted area of use" on the display 9 and outputs a tone to the speaker 15 to enter the restricted area of use. Notify the user. In addition, the call control function 51 uses the fixed-information 6 power-off timer 6
If the timeout time set to 2 is other than "0", the power OFF timer is started. And power off
When the timer times out, the call control function 51 instructs the state monitoring function 52 to turn off the power, and the state monitoring function 52 outputs P
-Set power-off information (for example, "1") in the OFF register. When the power-off information is set in the P-OFF register, the mobile station MS is powered off by hardware processing.

As described above, even if the entry into the use-restricted area is detected, the power of the mobile station MS is not turned off immediately but the power is turned off after a certain time elapses. This is to give time to see. This allows the user to know the reason for the automatic power off of the mobile station MS. If the set value of the power-off timer 62 of the fixed information 6 is “0”, the call control function 51 notifies the user with a tone sound but the power-off timer does not start, so the power of the mobile station MS is turned off. Not done. This is because there may be cases where different operators handle the restricted areas of use, so there is room to accommodate this.

In the case of use prohibition When the wireless zone type is “010”, the call control function 51 notifies the state monitoring function 52 of use prohibition control. Upon receiving this notification, the status monitoring function 52 requests the display operation unit 10 to display the message "prohibited area" on the display 9 and outputs a tone sound to the speaker 15 to enter the prohibited area. Notify the user. In the prohibited area, public facilities may be disturbed. Therefore, the power-off information is unconditionally set in the P-OFF register 11 to immediately turn off the mobile station MS.

Next, with reference to FIG. 8, some operation examples which differ depending on the situation such as the movement of the mobile station between wireless zones, the place where the power of the mobile station is turned on, and the setting value of the power-off timer will be described. It is assumed that the mobile station MS1 and MS3 in the figure have the power OFF timer 62 set to "0", and the mobile stations MS2 and MS4 have the power OFF timer 62 set to "1 minute". Here, the set value of the power OFF timer 62 is
The set time "0" means that the power is not turned off, which shows the elapsed time from when the mobile station is detected to enter the use refraining radio zone until the power is forcibly turned off.

The mobile station MS1 can receive normal service while in the available radio zone. When the mobile station MS1 shifts to (the zone of) the use refraining radio zone, a tone sounds to alert the user, but if the mobile station MS1 stays in the radio zone, the power is not turned off. Further, when the mobile station MS1 shifts to (a zone of) the prohibited radio zone, the power is immediately turned off with a tone.

The mobile station MS2 can receive normal service while in the usable radio zone (area), but when the mobile station MS2 shifts to the use refraining radio zone (area), a tone sound is emitted to alert the user, and the radio wave is emitted. After staying in the zone for another minute, the power is turned off.

Since the power of the mobile station MS3 is turned on in the zone where the mobile station MS3 is unwilling to use, a tone sounds to alert the user at the same time the power is turned on, but the power is not turned off if the mobile station MS3 stays in the wireless zone. . Mobile station MS3
When is moved to the prohibited wireless zone, the power is turned off immediately with a tone.

Since the power of the mobile station MS4 has been turned on in the zone where the mobile station MS4 is unwilling to use, at the same time, a tone sound alerting the user is emitted, and the power is turned off when one minute elapses after staying in that zone. To be done. Mobile station MS
In No. 5, since the power is turned on in the prohibited wireless zone (area), a tone sounds at the same time as the power is turned on and the power is immediately turned off.

Even when the power limiting function of the mobile station described above operates and the power is automatically turned off, the user may intentionally turn on the power again. Even in this case, there is no problem because the usage restriction function normally works again and the power is turned off. However, there are some places in the wireless zone where the radio waves are weakened locally due to interference, etc., so after the power of the mobile station is automatically turned off, the user moves to such a place and tries again. When the power is turned on, the mobile station cannot detect the broadcast information, so that the mobile station may remain powered on even though it is in the prohibited area. In order to deal with such a situation, the mobile station MS of this embodiment performs the following operation.

When the power of the mobile station MS is turned on, the call control function 51 activates a perch restriction timer. The timeout time of the perch limit timer is set in the perch limit timer 63 of the fixed information 6 in units of seconds. When the radio wave at the place where the user turns on the mobile station MS is weak and the reception level of any of the perch channels is less than or equal to a predetermined value, the mobile station MS cannot detect the broadcast information in the standby operation. When the perch restriction timer times out in that state, the call control function 51 notifies the state monitoring function 52 of use prohibition control. The status monitoring function 52 that has received this notification is the speaker 15
A tone sound is output to the user to notify the user that the use is prohibited, and P-
Set the power-off information in the OFF register 11 and the mobile station M
Turn off the power of S. Further, when the notification information is detected before the perch restriction timer times out, the call control function 51 stops the perch restriction timer and executes the above-described normal use restriction processing.

The present invention is widely applicable to mobile communication systems in general such as a car telephone system, a mobile telephone system, and a PHS (personal handy phone system). Also,
When the present invention is applied to a mobile communication system having a small cell (coverage area of a wireless base station), a prohibited area or a restricted area can be locally provided, so that, for example, only one hall of a building is prohibited. It is possible to make detailed restrictions such as making it into an area.

In the above-mentioned embodiment, the use limitation is performed by turning off the power of the mobile station, but other use limitation such as partially stopping the function of the mobile station so as not to adversely affect public facilities and the like. A method is also possible.
