Abstract

PURPOSE:To efficiently use a file memory in common, by performing the write/ readout/transfer among exchanges to a file memory in common use for each exchange in the common format, through the correspondence of data at various terminals to one common format. CONSTITUTION:In dialing a selected code at a terminal 1, a network controller in a common control section 10 connects the terminal 1 and an FAX trunk 6 via a bus 20. Then, this data is fetched to a file memory 17 to store and exchange the data at the terminal 1. This is performed by connecting the trunk 6 and a data controller 11 via a bus 21 through a file memory controller 16. The data are converted into a common format at the controller 16. Thus, the data storage file memory at various terminals can be used in common, allowing to simplify and economize the system.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a file memory sharing method suitable for a switching network that provides complex switching services.

In recent years, studies have been underway on integrated switching service networks that accommodate different services such as telephones, fax terminals, and data terminals in the same switching system (for example, IEICE technical research report SEs).

-62).

In the exchange system of this exchange service network, since the data format of each stock service is different, files for the exchange system are usually provided separately for each service, but this makes the system convenient. It becomes complicated and uneconomical.

The object of the present invention is to provide the above-mentioned composite exchange system,
Data from various terminals, which is information to be exchanged, can be efficiently stored in one file memory. The purpose is to provide a method for sharing file memory.

The present invention makes the data of various terminals correspond to one common format, and uses this common format to read and write to and from the shared file memory of each exchange and transfer to the exchange, and to connect each lumber terminal and the data stored therein. The present invention is characterized in that, when data is transferred between the exchange and g), the common control section of the exchange converts the data of various terminals into a common format.

The present invention will be explained below with reference to examples. FIG. 1 shows an example of the block configuration of one exchange in a composite exchange service network to which the present invention is applied. Telephone 2. Data terminal 3. The video telephone set 4 and the like are housed in a switching network 5.

A fixed number of trunks for fax terminals 6, trunks for telephones 7, and trunks for data terminals 8 are contracted to a certain number depending on the call traffic. They are respectively connected to trunks 9 for video telephones. Each of these trunks is a repeater that connects to an upper level integrated service network. On the other hand, the common control unit 10 includes network controls 1, 2, . ) rank control 13, processing unit 14. Main memory 15 that stores a program that performs target processing. File memory controller 16. It is equipped with a data controller 11 that takes in and sends out data from various terminals via the trunk, and is connected to a shared file memory 17 that stores data contents from various terminals.

Next, this operation will be explained using the connection of the facsimile terminal 1 as an example. When the fax terminal 1 is activated and a selection code is dialed, this is detected by means (not shown), and the network controller 12 in the common control section 10 connects the fax terminal 1 and the fax trunk 6 via the bus 20.
Connect with. Next, in order to store and exchange the data of the fax terminal 1, it is necessary to import the data of the fax terminal 1 into the file memory 17, and for this purpose, the fax trunk 6 and the data controller 11 are connected via a path 21.

Once this connection operation is completed, the fax trunk 6 sends the data from the fax terminal 1 to the data controller 11, and the processing unit 14 transfers the data from the data controller 11 to the file memory controller 16 through the internal bus 18. File memory controller 1
6 converts the data from the fax trunk 6 into a common format as shown in FIG.

Here, the common format is label LVL,! -f-
It consists of p DATA, and the label LVL is the originating terminal.

It is a collection of information related to data such as the data type of the receiving terminal and the data length. By using this common format, data from various terminals can be exchanged using a shared file.

When transmitting data from the fax terminal 1 to the upper service integrated network, the data is read from the file memory 17 and sent via the data control 511 fax trunk 6 to the upper service integrated network in a common format.

When the fax terminal 1 receives data, the data from the upper service integration network is simply stored in the file memory 17 in a common format. Thereafter, this data is read out from the file memory 17, a route to the terminal to be connected is established based on the contents of the label therein in the same manner as in the transmission described above, and the data is sent out to the fax trunk 6 via the data controller 11. 7ax) Rank 6 converts the common format data from the file memory 17 into data for the fax terminal and sends it to the fax terminal 1.

Although the case of fax has been described above, the same applies to telephone data terminals, video telephones, etc.

As is clear from the above embodiments, according to the present invention, in a complex service exchange network, the file memory for data storage for each food terminal can be shared, thereby simplifying and making the system more economical. can.
