Abstract

PURPOSE:To cooperate a real time system such as a call processing function and a non-real time system such as a UNIX function by adding said UNIX function to a processor having the call processing function. CONSTITUTION:A call control part 12 classifies terminal information transmitted from a communication control part 9 into UNIX service information and call processing information other than former information. The call control part 12 executes activating and stopping UNIX services or judges the transfer of information. When an activation request or a stop one is issued, the control part 12 activates a UNIX service control part 13-1. When the transfer request of information to the UNIX function 11 is issued from the side of the communication control part 9, the information is reported to a transmission control part 13-2 through the call control part 12. The transmission control part 13-2 writes information on a communication file having been already opened. The side of the UNIX function 11 reads out information from the opened communication file with an FIFO constitution.

Description

[Detailed Description of the Invention] [Summary] In a storage program controlled electronic exchange, a computer general-purpose OS function, such as UNIX, is added to a processor with a call processing function, and a FIFO-configured information communication file and an information control management section are created. .

It is disclosed to provide a switch that harmonizes the non-real-time UNIX functions with the real-time call processing functions.

[Industrial application field]

The present invention relates to a storage program controlled electronic switching system, and more particularly to a storage program controlled electronic switching system in which a computer general-purpose OS function is added to a processor having a call processing function.[Prior art] One of the computer general-purpose OS functions is called UNIX. Function is known. With the UN I
It has the advantage of being able to handle each file in the same way as files.

On the other hand, conventional storage program controlled electronic exchanges generally have a configuration as shown in FIG.

That is, in Figure 9, numeral 1 is a subscriber terminal, 2 is a network node work, 3 is a subscriber circuit, and 4 is a line processor.

5 is an information relay section, 6 is a processor, 7 is a send signal memory, and 8 is a receive signal memory.

In an electronic exchange having the configuration shown in FIG. 5 above,
Consideration was given to enabling the subscriber terminal 1 to utilize the UNIX functions described above. but.

The processor equipped with UNIX and the processor 6 that performs call processing shown in FIG. 5 are independent from each other. For this reason, even if an attempt is made to use UNIX functions, a computer with the UNIX functions described above is connected as one of the subscriber terminals to the network 2 shown in FIG. and the computer with the UNIX function are connected via the network 2 in a pass-through manner.

[Problem that the invention seeks to solve]

In the case of the conventional aspect described above, only services unique to computers with UNIX functions can be provided as services at subscriber terminals. That is, in this case, there was a problem in that it was not possible to make effective use of both the call processing function and the UNIX function.

In other words, only in an end-to-end state in which a bus via a network is set up between a subscriber terminal and a computer equipped with UNIX, the subscriber terminal is connected to the UNIX computer.
The functions of X could not be used.

(Means for Solving the Problems) The present invention solves the above problems by adding a UNIX function to a processor having a call processing function, and in this case also supporting the above call processing. The real-time system and the above U
Correct cooperation with non-real-time systems compatible with NIX is made possible.

FIG. 1 shows a block diagram of the principle of the present invention.

Reference numeral 6 in the figure corresponds to that in FIG. 1, and 9 is a communication control unit.

10 is a call processing function, 11 is a UNIX function, 12 is a call management section, 13 is an information control management section, 14 is a transmission information communication file, and 15 is a reception information communication file.

The information control management unit 13 manages information transmission and reception between the communication control unit 9 and the UNIX function 11 via information communication files 14 and 15. In addition, information communication file 14.15
are FIFO-configured files, and serve as a buffer between the real-time system and the non-real-time system.

[Effect]

The communication control unit 9 communicates with subscriber terminals by transmitting and receiving information to and from the send signal memory SSM and receive signal memory R3M shown in FIG.

Then, as in the conventional case, the call processing function 10 operates under the control of the call management section 12. In the case of the present invention, the processor 6 includes a UNIX function 11, and an information control management section 13.

It manages the transmission and reception of information between the communication control unit 9 and the UNIX function 11. During this time, the information is sent and received in a file 14.15 with a FIFO structure as shown in the figure.
X function 11 writes information.

And it is done by reading.

〔Example〕

FIG. 2 shows the main part configuration of the information control management section. The numbers 9, 10, 11, 12, 13, 14, and 15 in the figure are the first
Corresponds to the diagram. Reference numeral 13-1 represents a UNIX service control section, 13-2 a transmission control section, 13-3 a reception control section, and 13-4 a call management interface section. In addition.

Solid line arrows represent control, and double dotted line arrows represent information.

The terminal information sent from the communication control unit 9 is sent to the call management unit 12.
distinguish between UNIX service information and other call processing information. And the call management section 12.

It determines whether to start or stop UNIX services or transfer information, and starts the UNIX service control unit 13-1 when requesting start or stop.

FIG. 3 is a block diagram summarizing the functions of the information management section, and the reference numerals 13.13-2 and 13-3.1 in FIG.
4.15 corresponds to Figure 2.

13-5 is a hunt control unit that hunts communication files; 13-6 is a registration system i unit that performs registration processing with used files; and 13-7 is a release control unit that is used. It represents something that performs the process of releasing files.

As will become clearer when referring to the explanatory diagram at the time of information transmission shown in FIG.
hunted file number and UNIX
In addition to notifying the function 11 side, the hunted file is opened based on the registration control unit 13-6. UNI
When the X function II side receives the file number, it registers the communication file and opens the communication file.

When a transfer request is made from the communication control unit 9 side to the UNIX function 11, information is notified to the transmission control unit 13-2 via the call management unit 12. The transmission control unit 13-2 writes to the previously opened communication file. UNIX
On the function 11 side, information is read from the above-mentioned open FIFO-configured communication file.

When the transfer corresponding to the transfer request is completed, the state shifts to the "end" state shown in Figure 1, and the information control management section closes the previously opened communication file based on the release control section 13-7. release it. On the UNIX function side, when the end of data is determined, the communication file is closed.

When a transfer request is made from the UNIX function 11 side to a subscriber terminal, control is performed by the reception control unit 13-3 shown in FIG.
J says ``Read the communication file as J.''

(ii) The direction of information passing through the communication file (the direction of the white arrow in the figure) is reversed, and (iii) r communication file read J becomes [communication file write J.

Substantially similar control is performed.

The call management interface unit 13-4 shown in FIG. 2 performs interface processing for the call management unit 12 by the information control management unit 13, and performs processing corresponding to the call processing function 10 performed by the call management unit 12. In other words, priority is given to processing requests from the real-time call processing function 10, and the UNIX function 11
