Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention converts connection requests uniquely generated from terminals accommodated in a plurality of subscriber lines into one communication request,
In other words, it is related to a method of treating the request as a pair connection request and performing an exchange connection.

[Conventional technology]

In conventional switched networks, one subscriber line and one trunk line are generally used for connection and communication for one communication.

However, with recent advancements in communications, one subscriber can simultaneously use multiple subscriber lines and trunk lines through multiple terminals or multiple terminals, and use the same communication processing equipment or exchange within the exchange network. There may be cases where you want to communicate with someone.

For example, while audio is being sent over one line, data may be sent over another line.

However, a communication processing device is something that is built into or connected to an exchange, and has traditionally been installed in an exchange for subscriber services such as message services, calculation services, information provision services, and reservation services. This is what is being done.

Conventionally, if a data communication request (communication 2) is made on another line while voice communication is in progress (communication 1) on one line, the two sides are connected as independent communications as known, so the other party's address, communication reservation, etc. information etc.
Common information related to communication 1 and communication 2 needs to be independently input to the network multiple times. Furthermore, information regarding subscribers (calling class, etc.) needs to be duplicated and stored independently in the network for each station line, resulting in completely wasteful processing.

In addition, even in cases where a huge amount of data is sent in parallel to a communication processing device through two or more lines, the transmission is completed in a short time, and processing is performed quickly. Conventional networks do not know that a request is sent split over two lines, so it is treated as a separate communication and cannot be processed as a single communication request.

In this way, in conventional exchanges, communications requested independently from multiple lines are processed independently, and there is a function to treat multiple connection requests as one connection request or an additional connection request for one connection. There was no service for connecting multiple lines. In addition, the communication processing device connected via the relay line had the disadvantage that it could not determine whether calls received through multiple relay lines were a pair of connection requests from the same subscriber. .

For this reason, conventionally, it has been common knowledge that services using multiple connection lines for one communication cannot be provided.

Furthermore, since the exchange cannot determine whether a single communication request is made using a pair of multiple office lines, charges must be added up independently using the billing meter installed for each office line. There is a problem in that multiple meters are used in vain, and the total amount cannot be displayed on the bill to the subscriber.

Additionally, conventionally, since a communication processing device cannot determine which subscriber line is paired, the number of the other party's communication processing device must be dialed from one of multiple subscriber lines connected to multiple terminals or multiple terminals. Therefore, it was not possible to make a call and then receive the call via the communication processing device to another subscriber line that forms a predetermined pair. If this is possible, when data is sent to the communication processing device using one of the multiple subscriber lines in a pair, the communication processing device processes the data and detects an unknown point. In such cases, it is possible to receive a call using the other paired line and ask questions about unclear points by voice, thereby further improving the service provided to the subscriber.

[Purpose of the invention]

The purpose of the present invention is to solve such conventional problems, and for a terminal having two or more subscriber lines housed in an exchange, to determine whether or not there are multiple subscriber lines that are paired on the exchange side. It is an object of the present invention to provide a multi-office line pair connection system in which communication requests from a plurality of subscriber lines can be regarded as one communication request.

[Summary of the invention]

In order to achieve the above object, the multiple office line pair connection system of the present invention is such that a connection request originating from a terminal connected to two or more subscriber lines accommodated in an exchange is relayed to the above exchange or to the exchange. In a switching network that has a communication processing device built-in or connected to one of the relay exchanges connected via a line, for each subscriber number either in each of the above-mentioned exchanges or in the communication processing device. Management that includes a memory area in which terminal numbers are registered to allow paired communications to be regarded as one communication request, and a memory area to display that a paired line has been set for each terminal number. By providing a table and indexing the management table by calling subscriber number,
Determine that communication requests from multiple subscriber lines are connection requests that allow pairing, that is, one communication request,
It is characterized by connection processing.

[Embodiments of the invention]

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a system diagram of a switching network showing one embodiment of the present invention.

In FIG. 1, 1 to 3 are terminals used in pairs, where 1 and 3 are telephone terminals, and 2 is a data terminal. 4 to 6 are subscriber lines, 7
1 is a subscriber line exchange, 9 to 11 are trunk lines, 12 is a trunk line exchange, 8 is an ID device, 14 is a communication processing device, and 13 is a multi-office line management table newly provided for the present invention.

FIG. 1 shows a case where a communication processing device 14 is connected to a trunk switch 12. In FIG. Each of the terminals 1 to 3 is accommodated in a subscriber line exchange 7 through subscriber lines 4 to 6, and is further connected to a trunk exchange 12 via trunk lines 9 to 11. The subscriber line exchange 7 sends a caller identification number (ID number) to the relay lines 9 to 11 when the terminals 1 to 3 make a call, so it uses a subscriber number identification device (hereinafter referred to as an ID device).
8.

In the embodiment shown in FIG. 1, the multiple office line pair management table 13 is searched using the originating subscriber number transmitted from the ID device 8 as a keyword.

Note that the management table 13 may be built into the communication processing device 14 as shown in FIG. 1, or may be built into the trunk switch 12.

As shown in FIG. 1, in the management table 13,
A memory 19 in which terminal numbers that permit paired communication are registered in advance for each subscriber number, and memories 23 and 24 that display that a paired line has been set for each terminal number registered therein , and a memory 27 which is a comprehensive billing meter for a pair of office lines is stored.

First, the operation when terminals 1, 2, and 3 are sequentially connected to the communication processing device 14 as a pair of office lines by a subscriber call will be described.

The dial number for making a connection request to receive the service of the communication processing device 14, that is, the connection number is
For example, the 3-digit number 15 is shortened from the normal dial number. When terminal 1 dials connection number 15 to communication processing device 14, subscriber line exchange 7
selects the trunk line 9 and connects it to the trunk exchange 12, and the trunk exchange 12 further connects the trunk line 9 to the communication processing device 1.
Relay connection to 4. From the terminal 1 to the communication processing device 14
When the train up to is set, the subscriber line exchange 7 uses the ID device 8 to transmit the number 16 of the terminal 1 to the communication processing device 14 as an ID signal.

The communication processing device 14 connects the terminal 1 and the communication processing device 1
The table 13 is searched using the number 16 sent before terminal number 4 started communication as a keyword, and the memory 19 corresponding to the terminal number 16 is indexed. Then, a communication status display, for example "1", is set in the communication status display area 20 of the memory 19. Note that numbers 17 and 18 of terminals 2 and 3 that are allowed to communicate with terminal 1 in advance are stored in memory areas 21 and 22 in memory 19.
is registered. The communication processing device 14 indexes the memories 23 and 24 using numbers 17 and 18 in the memory 19 as keywords, and uses the numbers 17 and 18 in the memory 19 as keywords.
The number 16 of the terminal 1 in communication is set in the memory areas 25 and 26 in the memory area 25 and 26. When the above processing is completed, the terminal 1 and the communication processing device 14 enter a communication state.

Next, dial connection number 15 from terminal 2.
The subscriber line exchange 7 selects the trunk line 10 and connects it to the trunk exchange 12 , and then the trunk exchange 12 connects it to the communication processing device 14 . When a train from the terminal 2 to the communication processing device 14 is set, the subscriber line exchange 7 uses the ID device 8 to send out the number 17 of the terminal 2 as an ID signal.

The communication processing device 14 searches the table 13 using the number 17 as a keyword and indexes the memory 23 corresponding to the number 17.
Since the number 16 is already stored in the area 25, it is determined that the communication is a pair with the communication between the terminal 1 and the processing device 14, which are already communicating. When it is determined that it is a paired communication,
The memory in the memory 19 that manages the original communication.
A communication status indicator "1" is set in the area 20' to indicate that there is communication between the added terminal 2 and the device 14. As a result, the terminal 2 and the communication processing device 1
4 can also be communicated with.

In the same way, when there is a call from terminal 3,
Using the number 18 as the ID signal as a keyword, the memory 24 is indexed from the table 13, and a communicating indicator "1" is set in the memory area 20'' of the memory 19 from the number 16 of the memory area 26 there. This enables the terminal 3 and the communication processing device 14 to communicate.

The above ensures that all communications sent by terminals 1 to 3 are paired.

The memory 27 in the management table 13 is a billing meter for the terminal 1, and all charges for paired communications are registered here. For example, when the communication between the terminal 1 and the device 14 ends, the fee is added to the previous value, and then when the communication between the terminal 3 and the device 14 ends, the fee is added to the value in the memory 27,
Finally, when the communication between the terminal 2 and the device 14 ends,
The fee is also added to the value in the memory 27. In this way, the total charge for the pair of connections can be registered by addition.

Next, while the terminal 1 and the communication processing device 14 are communicating,
A case where it is desired to receive a call from the processing device 14 to the terminal 2 or 3 will be described.

First, in order to connect to the communication processing device 14 from the terminal 1, by dialing the connection number 15, a relay connection is established in the same manner as described above. Then, the communication processing device 14 sets a communication display in the area 20 of the memory 19 in the management table 13,
Further, the number 16 of the terminal 1 is set in areas 25 and 26 of the memories 23 and 24. As a result, the terminal 1 and the communication processing device 14 enter into a communication state via the relay line 9.

When communication processing device 14 encounters an unknown point during communication with terminal 1 or detects an error in received data, communication processing device 14 accesses table 13 and registers information in memory areas 21 and 22 of memory 19. A call is made from the communication processing device 14 using one or both of terminal numbers 17 and 18. Thereby, the trunk line exchange 12 can receive a call to the terminal 2 or 3 via the subscriber line exchange 7.

Note that the terminals 1 to 3 can be connected in exactly the same way even if they are not separate terminals as shown in FIG. 1, but are physically light composite terminals.

In addition, when making a call from the communication processing device 14 after the terminal 1 is connected to the communication processing device 14, the terminal 1
As in the past, it is possible to connect not only to 3 to 3 but also to independent terminals, that is, unpaired terminals.

Further, although the communication processing device 14 is connected to the trunk switch 12 in FIG. 1, the present invention can be applied even if the communication processing device 14 is installed inside the trunk switch 12.

Further, although FIG. 1 shows a case where the trunk lines 9, 10, and 11 are real lines, the same method can be applied even in the case of time division multiplex lines by pairing channels.

FIG. 2 is a system diagram of a switching network showing another embodiment of the present invention.

FIG. 2 shows a case where the communication processing device 14 is connected to the subscriber line exchange 7. In FIG. In FIG. 2, symbols 1 to 7 represent the same ones as in FIG. 1, and 14 is a communication processing device;
Reference numeral 3' denotes a plurality of station line pair management tables, and 29 a memory for station line pair registration numbers, communication status display, and charge registration for each subscriber number.

In FIG. 2, each memory is not provided independently in the table 13', but only one memory 29 is provided for each subscriber number, and each area is contained within the memory 29. This memory configuration is, of course, the first
It can also be applied to diagrams.

Furthermore, in FIG. 2, the management table 13' does not have to be built into the communication processing device 14;
It is sufficient if it is built into the subscriber exchange 7. Furthermore, the communication processing device 14 may be built into the subscriber line exchange 7.

When the terminal 1 dials the connection number to the communication processing device 14, the subscriber line exchange 7 connects the terminal 1 to the communication processing device 14. In this case, the ID device shown in FIG. 1 is not required. Communication processing device 14
After connection, searches the table 13 using the terminal number sent from the exchange 7 as a keyword, and indexes the memory 29 corresponding to the terminal number. Then, in addition to setting a communicating display in the communicating display area 30 of the memory 29, the terminal Set the number 1 to indicate that communication is in progress.

As a result, the terminal 1 and the communication processing device 14 enter a communication state. Further, when connected to the terminals 2 and 3 on the way, a communication display is set in the corresponding communication display area 30 of the memory 29. Each terminal 1,
When communication with 2 and 3 is completed, each charge is added to the previous value and the total value is stored in area 37.

In this way, a plurality of office line pairs can be connected not only with the communication processing device connected to the trunk exchange, but also with the communication processing device connected to the subscriber line exchange.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to determine whether or not a terminal having two or more subscriber lines accommodated in an exchange is a pair of multiple subscriber lines on the exchange network side. Therefore, it is possible to improve services for subscribers who communicate using multiple office lines simultaneously.
