In general, the radio mobile station 5 and the radio call receiver 8 according to the present embodiment configured as above notify the user visually or audibly when a call is made.

A dedicated transmitter 100 is provided at a designated location of the ringing prohibited area, and a service area 200 of the dedicated transmitter 100 is provided.
Depending on the range, etc., it is possible to use a low power transmission output, and periodically or continuously notifies the radio mobile station 5 and the radio paging receiver 8 of a ringing prohibition signal.

The operating frequency of the dedicated transmitter 100 is a frequency (for example, FM frequency) of a frequency band used for an existing radio broadcast and the like which can be configured as an inexpensive transmitter, and a transmission power (for example, about 10 mW) by small power. It is desirable to use an existing digital transmission system (for example, MSK system) or simply transmit the carrier using a dedicated frequency (eliminating the control signal and judging based on the level of the carrier level to be transmitted). it can.

When the radio mobile station 5 or the radio paging receiver 8 is located in a ringing prohibited area, which is a specific place where a ringing tone is annoying to a person, the radio mobile station 5 or the radio paging receiver is set. 8 receives a ringing inhibition signal from the dedicated transmitter 100, and when it is determined that this area is a target area of ringing inhibition, automatically sets a silent state,
The ringing is not performed by the audible sound.

When a call is made from the radio base station 4 to the radio mobile station 5 in the ringing prohibition area, a response is sent to the radio base station 4 indicating that the radio mobile station 5 is located in the ringing prohibition area, and the ringing is further performed. That you are in a prohibited area,
The received call information is displayed in a silent state, and is stored until the user confirms the call information, thereby notifying the user.

When there is a call from the peripheral base station 7 to the radio paging receiver 8 in the call ringing prohibited area, it is determined that the user is in the call ringing prohibited area and the received message information is in a non-ringing state. The display is memorized and notified to the user.

When the radio mobile station 5 or the radio paging receiver 8 moves out of the ringing prohibited area, the radio mobile station 5
Alternatively, the radio paging receiver 8 continues to receive the ringing prohibition signal from the dedicated transmitter 100, and when the level of the carrier of the received signal becomes equal to or less than the specified value, it is determined that the area is not the area for which the ringing prohibition is prohibited. When the judgment is made, the original sounding state is automatically restored.

Further, when the radio mobile station 5 is receiving the ringing prohibition signal, the radio base station 4 notifies the radio base station 4 that it is in the ringing prohibition area by an incoming call response signal. The switching network 3 may be configured so that the radio base station 4 can recognize that the wireless base station 4 is in the ringing prohibited area. As a result, as an existing service function of the mobile communication network, it is possible to link with an absence announcement service to a caller, an answering service, and the like.

As described above, according to the present invention, a ringing prohibition signal is continuously or intermittently notified and transmitted in advance to a special place as a ringing prohibition area of a radio telephone device or a radio pager for a necessary period. A dedicated transmitter 100 is installed to prevent the radio mobile station 5 and the radio paging receiver 8 from receiving the signal by the dedicated receiver 110 having the signal built therein, and to perform a self-audible calling. It is.

Naturally, when the ringing prohibition signal cannot be recognized continuously for a specified time, the normal ringing operation is restored.

The dedicated transmitter 100 for transmitting the ringing prohibition signal uses a frequency band and a transmission method (for example, an MSK signal) used in an existing radio broadcast or the like in order to realize the lowest possible cost. Thus, the dedicated receiver 110 incorporated in the radio mobile station 5, the radio paging receiver 8, and the like can be realized at extremely low cost.

The dedicated receiver 110 has a mechanism for periodically (for example, 30 seconds) sensing a predetermined control frequency to confirm the presence of a ringing inhibition signal.
The operation of “0” and the operation of receiving the call signal from the original radio base station 4 and the peripheral base station 7 are configured to be able to function in parallel.

The structure of the above-mentioned ringing inhibition signal is ideally determined as a reliable information by a digital signal, and a method of making a judgment based on the content of this information is ideal. However, considering cost, only the carrier of the ringing inhibition signal is considered. , Or by checking a specific modulation signal (for example, an MSK modulation signal).

[0038]

As described above, according to the present invention,
A ringing prohibition signal is reported and transmitted by a dedicated transmitter provided in the ringing prohibition area, and a ringing prohibition signal is received and prohibited by a dedicated receiver provided in a radio mobile station or a radio paging receiver. Judge the area. A non-ringing state that does not automatically ring with an audible tone for calls in the ringing prohibited area, and a person-friendly wireless device that automatically rings when moving out of the ringing prohibited area. Can be realized.

Further, the dedicated transmitter and the dedicated receiver to be added to the radio mobile station and the radio pager can be realized at low cost by using existing components.

Further, the dedicated transmitter, the radio mobile station, and the radio call receiver according to the present invention have an effect that the addition or the change of the function can be flexibly handled by the software program of the CPU or the ROM.
