Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paging system for calling a receiving device with a calling signal from a radio calling device connected to an exchange.

[0002]

2. Description of the Related Art Conventionally, as a paging system of this type, there are those shown in FIGS. 4 and 5, for example. In the paging system shown in FIG. 4, when there is a call from a caller, the exchange (not shown) activates the call signal transmission circuit 101 of the radio communication apparatus 100, and the call signal transmission circuit 101 causes the reception apparatus 110 to call. The call signal is wirelessly transmitted. In the reception device 110, when the call signal reception circuit 111 receives the call signal, the buzzer 112 sounds. Also,
In the wireless calling device 100, a calling signal is transmitted to the accepting device 110, and at the same time, a message to the effect that "calling" is being sent from the announcement trunk 102 to the calling party via the exchange.

On the other hand, in the paging system shown in FIG. 5, when a caller makes a call, the call signal transmission circuit 201 of the radio calling apparatus 200 wirelessly transmits a call signal to the reception apparatus 210, and the selector control circuit 202 causes the selector control circuit 202 to make a call. The selector 203 is controlled so that the calling circuit 205 of the announcement trunk 204 sends a message to the caller indicating that "calling". On the other hand, in the reception device 210,
When the ringing signal receiving circuit 211 receives the ringing signal, the buzzer 212 is sounded, and at the same time, the reception signal transmitting circuit 213 transmits an acceptance signal to the radio pager 200. Then, in the radio calling device 200, when the reception signal reception circuit 208 receives the reception signal, the selector control circuit 202 controls the selector 203 to “receive” the call from the call reception confirmation circuit 206 of the announcement trunk 204. It is designed to send a message to that effect. When it is determined that the incoming call is not received, a message to that effect is sent from the incoming call disable circuit 207 to the caller.

[0004]

However, the above-described conventional paging system has the following problems.
In the paging system shown in FIG. 4, the radio calling device 1
When the call signal is transmitted from the call signal transmitting circuit 101 of 00 to the accepting device 110, the announcement trunk 1
Since 02 only sends a message to the caller indicating that the call is being made, there is a problem that the caller cannot judge whether the call signal actually arrives at the reception device 110.

On the other hand, in the paging system shown in FIG.
When the reception signal from 0 is received, the incoming call confirmation circuit 206 of the announcement trunk 204 "receives" the caller.
Since the message to that effect is sent, the calling party can determine that the calling signal from the wireless calling apparatus 200 has arrived at the receiving apparatus 210 and is calling the called party. However, when the called party is away from the accepting device 210, even if the buzzer 212 rings, it cannot be recognized as being called. Therefore, in such a case, the calling party cannot judge that the called party does not recognize what is called. That is, this paging system has a problem that the calling party cannot judge whether the call is transmitted to the called party.

As a technique similar to the technique shown in FIG. 5, published patent publications No. 505512, 1993, No. 503737, and application publication No. 1982, No. 82.
