Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a radio selective calling device for transmitting a radio selective calling signal and a plurality of selective calling receivers for alerting the call upon receiving the radio selective calling signal including its own calling number. The present invention relates to a paging system having an emergency alert notification function.

[0002]

2. Description of the Related Art In a conventional paging system, in order to notify a selective call receiver of an emergency alert such as the issuance of a warning declaration, the selective call receivers are individually called or a plurality of predetermined selective call receivers are called. It is urgent to call individually or to group a plurality of selective call receivers with the same call number and to call the selective call receivers in group units (for example, Japanese Patent Laid-Open No. 4-329035). I was giving an alarm.

[0003]

In the above-mentioned conventional paging system, when all the selective calling receivers are individually called, the wireless selective calling device needs to transmit a huge number of radio selective calling signals. There was a drawback that it was not the target. Further, when the selective call receivers are called in units of groups, there is a drawback that the selective call receivers outside the group cannot be called.

Therefore, an object of the present invention is to solve the above-mentioned drawbacks of the paging system according to the prior art and to call all of the selective call receivers at the same time, thereby providing a paging system having an emergency alert notification function capable of giving an emergency alert at once. To provide.

[0005]

A paging system having an emergency greeting notification function according to the present invention receives a radio selective calling device for transmitting a radio selective calling signal and the radio selective calling signal including its own calling number. A paging system comprising a plurality of selective call receivers for performing call notification, wherein the radio selective call signal has an individual call signal having an individual call number for individually calling each of the selective call receivers, There is a paging signal having a paging number for paging the selective paging receivers all at once, and the radio selective paging device is connected to an individual paging means for transmitting the individual paging signal when receiving the individual paging instruction signal from the public network. A selective control call and a general call means for transmitting the general call signal when receiving the general call instruction signal from the public network. Each respective signal machine, perform call informing in response to said selective calling signal and the paging signal with its own call number.

In the paging system having the emergency alert notification function, when the paging system receives the paging instruction signal from the public network, the paging system includes a predetermined password. Only, it is possible to adopt a configuration for transmitting the paging signal.

The radio selective calling device of this paging system normally sends an individual calling signal to call the selective calling receiver individually. However, when receiving a paging instruction signal in an emergency, this radio selective calling device transmits a paging signal to call all the selective calling receivers at the same time.

[0008]

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a paging system having an emergency alert notification function according to an embodiment of the present invention.

This paging system comprises a radio selective calling device 3 for transmitting a radio selective calling signal from an antenna 4,
A plurality of selective call receivers are provided to notify the call when the received wireless selective call signal recognizes its own calling number. In FIG. 1, a plurality of selective calling receivers 5 are represented by one selective calling receiver 5. Radio selective calling device 3
Is connected to the public network via an incoming trunk (ICT) 1. Upon receiving an individual call instruction signal for individually calling each of the selective call receivers 5 from the telephone of the public network, the wireless selective call device 3 transmits an individual call signal which is one of the wireless selective call signals from the antenna 1. . The individual call instruction signal and the individual call signal include an individual call number uniquely possessed by each of the selective call receivers 5, and only the selective call receiver 5 having the individual call number has the individual call number. Call notification is performed by receiving a call signal.

The radio selective calling device 3 also transmits a paging signal, which is another one of the radio selective calling signals, to all the selective calling receivers 5 for emergency calling. The paging signal includes a paging number for paging all of the selective paging receivers 5 at the same time. Then, all of the selective call receivers 5 that have received the simultaneous call signal issue a call alert for an emergency alert by changing the ringing pattern as compared with the case of an individual call, assuming that the emergency alert notification has been received.

One of the calling instructions of the general calling signal is issued from the control console 2 operated by the operator. The control console 2 is a device that performs various controls on the radio selective calling device 3. When the control console 2 sends a paging instruction signal including a paging number to the radio selective calling device 3, the device 3 sends the paging signal from the antenna 4 to call all of the paging receivers 5.

Another one of the calling instructions of the general calling signal is sent to the radio selective calling device 3 from a telephone of a predetermined organization connected to the public network. That is, when the wireless selective calling device 3 receives the general calling instruction signal from the public network, it transmits the general calling signal from the antenna 4 to call all the selective calling receivers 5. However, when the wireless selective calling device 3 receives the general calling instruction signal from the public network, it transmits the general calling signal only when the general calling instruction signal includes a predetermined password. To confirm this password, the paging signal is used as a warning alert notification for all selective call receivers 5.
This is because it is used for calling a call, and has a great influence, and is for preventing the simultaneous call instruction signal from being misused by the public network.

FIG. 2 is a flow chart showing the operation of the selective call receiver 5 in the embodiment of FIG. 1 at the time of call notification.

The selective call receiver 5 receives the radio selective call signal (step 2) during standby (step 1). Then, the selective calling receiver 1 determines whether or not the calling number included in the received wireless selective calling signal matches the unique individual calling number, and determines whether the received wireless selective calling signal is the individual calling signal addressed to itself. It is determined (step 3). If the received radio selective call signal is an individual call signal addressed to itself (Yes in step 3), the selective call receiver 5 gives a normal call notification (step 4), and the flow returns to step 2.

In step 3, if the received radio selective call signal is not the individual call signal addressed to itself (No in step 3), the selective call receiver 5 determines that the call number included in the radio selective call signal is the general call number. It is determined whether or not the received radio selective call signal is a general call signal (step 5). If this radio selective call signal is a general call signal (Yes in step 5), the selective call receiver 3 gives a call alert for an emergency alert (step 6), and the flow returns to step 2. In step 5, if the received radio selective call signal is also not a general call signal (No in step 5), since no call has been received, no call notification is given and the flow returns to step 2.

[0017]

As described above, according to the present invention, the radio selective calling signal transmitted by the radio selective calling device has an individual calling signal having an individual calling number for individually calling each of the plurality of selective calling receivers, A paging signal having a paging number for paging the selective paging receivers at a time, wherein the radio selective paging device transmits an individual paging signal when receiving an individual paging instruction signal from a public network; A control console connected thereto and a paging means for transmitting the paging signal upon receiving a paging instruction signal from the public network, wherein each of the selective paging receivers includes the individual paging number. Since the call notification is performed in response to the ringing signal and the paging signal, all the paging receivers can be simultaneously called by sending the paging signal only once. There is an effect that can simultaneously notify the emergency alarm to the selective call receiver.
