Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a system for simultaneously instructing a plurality of low-cost line selection adapters (hereinafter referred to as "adapters") using a paging system or broadcast radio waves. Also, the present invention relates to an adapter simultaneous command system suitable for issuing a command for avoiding a relay line when a relay exchange in a certain area of a telephone service company (hereinafter, referred to as “carrier”) becomes unavailable.

(Prior art) Due to the demand to use a low-cost carrier in long-distance or medium-distance calls, an adapter that automatically selects the trunk line of the cheapest carrier among the trunk lines of multiple carriers has become practical. Has been provided.

Conventionally, when giving a command to each adapter, it has been performed using a telephone line. Specifically, a line accommodated in each adapter is called from an adapter center of a carrier, and a command is given using the telephone line.

For example, when the exchange of the carrier b in the city A breaks down, the line of the carrier b becomes unavailable when calling from the city A. Also, when calling from a region other than the city A to the city A, the carrier b is in an unusable state.

The adapter installed in the city A does not select the carrier b when making a call, and the adapter installed in a region other than the city A does not select the carrier b when making a call. It is necessary to give a command to the adapter so that only the carrier b is not selected.

Therefore, conventionally, a line accommodated in each adapter is called from the adapter center of the carrier b, and a command is given using the line.

(Problems to be Solved by the Invention) By the way, in the above-mentioned instruction method, since each adapter is called, when tens of thousands or hundreds of thousands of adapters are used, it takes a long time. Problems arise.

In other words, it takes a considerable amount of time before a command is given to all adapters after a switch failure, and an adapter with a delayed command may select an unavailable line during this time. .

In addition, since failures are usually recovered in about 10 minutes to one hour, before all adapters are commanded,
The exchange is restored and cannot respond to the failure of the exchange. This is because if recovery is performed in a very short time due to a failure of the exchange or the like, it is meaningless unless an instruction is immediately given to all adapters.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned drawbacks, and to provide an adapter simultaneous command system capable of simultaneously executing a specified process on a specified adapter in a short time.

(Means for Solving the Problems) In order to achieve the above object, a low charge line selection adapter simultaneous command system according to the present invention comprises a receiver for receiving the same paging call number in each low charge line selection adapter,
By transmitting the paging call number from a paging transmitter, the low-priced line selection adapters are simultaneously called to transmit a message section including a target code section and a processing code section, Line selection adapter
When the relay exchange etc. of the specific carrier in the specific area area becomes unavailable, the specific carrier indicated by the processing code section corresponding to the adapter in the specific area area indicated by the target code section is not selected. Is configured.

Further, the present invention includes a receiver for receiving the same broadcast radio wave in each low-cost line selection adapter, and simultaneously calls each of the low-cost line selection adapters by emitting the broadcast wave from a broadcast station transmitter. A command data section consisting of a target code section and a processing code section is transmitted, and a periodic command indicated by the processing code section or given to an adapter in a specific area area area indicated by the target code section Is configured to give a predetermined command.

(Example) Hereinafter, the present invention will be described in more detail with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of an adapter simultaneous command system according to the present invention.

This embodiment utilizes a paging system with a message.

All adapters 1 are provided with a paging receiving unit, and are provided with a common paging call number. The carrier adapter center 4 sends out a common calling number and command to each adapter through the paging transmitter 3.

When giving a command, the carrier adapter center 4 accesses the paging system. As a result, the paging transmitter 3 emits a predetermined frequency from the antenna 2 and, for example, calls a paging call number “12345678”. At this time, the contents of the command are sent in a message part.

Since all the adapters 1 have a common call number "12345678", all the adapters respond at the same time and a command is given all at once. Each adapter 1 is inserted into, for example, a subscriber line of each telephone terminal, and selects a relay line of a carrier having the lowest fee by calling from the telephone terminal.

The message part is divided into a target code part and a processing code part. The target code specifies the target adapter, and the processing code conveys the instruction content.

For example, it is assumed that, when the relay exchange of the carrier b in the city A is out of order, the toll station in the city A is set to the 0xx station and a command is issued to the adapter not to select the carrier b when calling the adapter.

At this time, the message part is “000xx00111”.
Here, “000xx” means the target adapter, and “00111” means the instruction content not to select the carrier b.

All adapters nationwide respond with "12345678",
Upon receiving the message, the adapter in the area of the 0xx station in the city A does not select the carrier b when calling. In addition, an adapter installed outside the area of the 0XX station outside the city does not select the carrier b only for the call to the 0XX station when calling.

In addition, when all adapters are targeted without being limited to adapters in a specific area, a code that targets all adapters, for example, “00000” may be used.

In the case of a paging service in which the use area is limited instead of a paging service for the whole country, it is necessary to send a command for each area.

FIG. 2 is a diagram showing another embodiment of the adapter simultaneous command system according to the present invention.

This embodiment uses a broadcast wave.

All the adapters 1 are provided with receivers that can receive a broadcast wave of a specific frequency so that only those frequencies can be received (for example, 1134 KHz cultural broadcast).

The command is transmitted at the time of advertisement of the broadcast radio wave.

When sending a command to the adapter, the carrier 5 transmits the content of the command to the broadcasting station 6, and the broadcasting station 6 transmits the command and emits a radio wave from the antenna 7. Since all adapters receive the same frequency, all adapters can receive the command at the same time.

The command content is composed of a target code part and a processing code part, like the message part of the paging system described above. The target adapter is specified by the target code, and the processing content is transmitted by the processing code.

If the broadcast radio wave to be used is not a nationwide broadcast, it is necessary to specify the broadcast radio wave to be used for each region and send a command for each region.

Since the use of broadcast radio waves is usually performed according to a schedule, it is necessary to apply in advance to a broadcast station even at the time of advertisement.

For this reason, a regular command or a command that has been known to be given for a long time can be given to the adapter as scheduled.

However, if a sudden event, for example, a failure of the relay exchange, causes a need to give a command to the adapter in a hurry, the problem remains that broadcast radio waves cannot be used immediately.

(Effect of the Invention) As described above, according to the present invention, since a large number of adapters respond simultaneously and receive a command, a command can be given to a large number of adapters in a very short time.

As a result, when a paging system with a message is used, even if a sudden event such as a failure of the exchange occurs, a command can be immediately given to all the adapters, so that a quicker response is possible. Similarly, when the exchange is restored, immediate response is possible.
