Abstract

PURPOSE:To have a general calling to plural subscribers designated by general calling telephone numbers, by providing a register which receives and stores the telephone numbers of called subscribers and a circuit which discriminates the general calling telephone numbers and produces calling numbers. CONSTITUTION:A registered general calling telephone number is dialed. Then the dialed number is transmitted to a radio calling device via a general telephone circuit 2 and stored in a receiving/storing register 5 for numbers of called subscribers. The register 5 actuates a collating and calling number producing circuit 6 to receive the storage information from the register 5 and to read out the contents of a general calling telephone number register memory 7 for collation. The call number designated from collation is transmitted to a radio device 4 to call the corresponding subscriber with a radio frequency in accordance with the calling number. In such a way, it is possible to call plural subscribers with just a single operation.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wireless paging system performed via a general telephone line.

In conventional wireless paging services, one calling operation calls one subscriber, so when calling multiple subscribers at once, the calling operation must be performed for each subscriber, and the caller The disadvantage was that it required many operations.

The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional technology. Therefore, the object of the present invention is to provide a novel system that allows simultaneous calling of multiple subscribers with a single call operation from the caller. The purpose is to provide a wireless paging system.

In order to achieve the above object, the wireless paging system according to the present invention compares the received and stored telephone numbers with a register that receives and stores the telephone number of the called party, and identifies the pre-registered simultaneous paging telephone number. When the general calling telephone number is received, a plurality of subscribers designated by the simultaneous calling telephone number are called at the same time.

Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a radio call relay system according to the present invention. In the figure, reference number 1 indicates the calling party's telephone, 2 indicates the general telephone line, and 3 to 3 indicate the telephone line of the calling party.
7 constitutes a radio paging device. In other words, 3 is an exchange, 4 is a radio, 5 is a register for receiving and storing called name numbers, 6 is a telephone number verification and calling number creation circuit, and 7 is a simultaneous calling telephone number registration memory.
A simultaneous calling telephone number registration memory 7 stores a simultaneous calling telephone number and a plurality of subscriber telephone numbers specified therein.

Here, if the calling party calls multiple subscribers at once,
When a pre-registered simultaneous calling telephone number is dialed, the call arrives at the radio paging device via the general telephone line 2, and is connected to the called party number reception and storage register 5, where the called party number is received and stored. ,! & When you receive the calling number,
Register 5 activates verification and calling number generation circuit 6.

This collation and calling number creation circuit 6 receives the accumulated information from the l/register and - simultaneous calling number registration memory 7
Read and check the contents. As a result of the verification, if it is a general calling telephone number, a plurality of subscriber telephone numbers specified therein are read out to create a calling number and sequentially sent to the radio 4. Thereafter, the radio device 4 makes a call using a normal radio frequency according to the calling number.

Incidentally, if the result of the verification is one subscriber's telephone number, only that subscriber is called.

The present invention has been described above with respect to one preferred embodiment thereof, but
These are merely illustrative, and it goes without saying that the present invention is not limited to the embodiments described here.

Present invention 1: As explained above, when a caller wants to call multiple subscribers at once, the caller can call multiple subscribers with a single call operation without having to perform a call operation for each subscriber. Therefore, the conventional radio paging service can be improved.
