Abstract

PURPOSE:To improve the convenience of a composite communication network by recognizing any case where a telephone call or a facsimile call is incoming in a composite communication network where the telephone call and the facsimile call are set so as to make an interruption function effective. CONSTITUTION:When the facsimile call is incoming newly while a subscriber n1 is talking, the facsimile call F is incoming to the subscriber n1 and an output request signal (i) is transmitted from a facsimile network storage exchange FS via a facsimile network relay exchange FT. Then a central controller CC of a subscriber managing exchange SS references a storage area M1 of a storage device MM so as to identify that the subscriber n1 is in busy, channels P7, P8 are set and a channel P6 is held. The telephone call P is talked via an interruption trunk OFT and a facsimile interruption communication signal is transmitted from the interruption trunk OFT to a telephone set T during talking.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a composite communication network in which telephone calls and facsimile calls having a store-and-forward function can be set up, and particularly to a subscriber who is communicating by telephone call or facsimile call. In contrast, the present invention relates to a different communication combination interrupt processing method that realizes an interrupt function when a different type of call arrives.

In a telephone switching network, a subscriber who is currently talking is notified of each new call received, and based on the subscriber's actions (e.g., hunking), the current call can be temporarily put on hold and the new incoming call can be answered. Interruption functions are becoming popular under the names of so-called call waiting and call waiting.

On the other hand, a composite communication network has been put into practice in which a facsimile terminal device is attached to a telephone set, and a facsimile network storage exchange is installed in a telephone exchange network, thereby making it possible to set up both telephone calls and facsimile calls.

[Conventional technology]

Conventionally, this type of composite communication network has been equipped with the above-mentioned interrupt function between telephone calls, but there is also an interrupt function when a new facsimile call arrives to a subscriber who is currently communicating on a telephone call, or a facsimile call. It did not have an interrupt function for when a new telephone call arrives to a subscriber who is currently communicating on a call.

[Problem that the invention seeks to solve]

As is clear from the above description, conventional composite communication systems have not been provided with an interrupt function between a facsimile call and a telephone call, which has a #product/exchange function.

Up until now, when facsimile terminals were not as popular as telephones, such an interrupt function was not as necessary. As it gradually increases,
The number of incoming calls between facsimile calls and telephone calls is also likely to increase, increasing the need for similar interrupt functionality between telephone calls.

[Means for solving problems]

This problem occurs in a complex communication network that accommodates subscribers who are equipped with telephones and facsimile terminals, and is capable of setting up telephone calls and facsimile calls that have a forwarding and forwarding function. means for notifying that the subscriber has received a call, and based on the operation of the subscriber who recognizes the notification, temporarily suspending the call in progress and setting up a new incoming call, or communicating without setting up a new incoming call. This problem can be solved by providing a control means for deciding whether to continue the current call.

[Effect]

That is, according to the present invention, in both cases when a new facsimile call arrives to a subscriber who is currently communicating with a subscriber, and when a new telephone call arrives to a subscriber who is currently communicating through a facsimile call, the subscriber It becomes possible to recognize new incoming calls, and at the subscriber's will, the existing call can be temporarily put on hold and the new incoming call can be answered, or the new incoming call can be rejected and communication using the existing call can be continued. This also makes it possible to realize a so-called interrupt function.

A telephone interrupt contact signal is transmitted from T to the facsimile terminal FAX that is in communication, furthermore, a call path p4 is set in the network NW, a ring trunk RBT is connected to the telephone network relay exchange PT, and the ring trunk The ringing tone sent out by the RBT is returned to the calling party of the telephone call P. The facsimile terminal device FAX that receives the telephone interruption communication signal turns on the telephone interruption indicator light. Subscriber n1 notices that the telephone interrupt indicator light is on, and in order to answer the newly arrived telephone call P,
When an interrupt start button provided on the facsimile terminal FAX is operated, the facsimile terminal FAX transmits an interrupt start request signal C to the subscriber management exchange SS. In the subscriber management exchange SS, the central controller CC sends an interrupt start request signal C via the interrupt trunk OFT.
When received, the facsimile network storage exchange FS is sent from the interrupt trunk OFT to the facsimile network trunk exchange FT.
A stop request signal d is transmitted to the stop request signal d. After receiving the stop request signal d, the facsimile network storage and exchange taFs transmits a stop completion report signal e to the subscriber management switch SS via the facsimile network relay switch FT when it finishes sending the image information a for the page being transmitted. . In the subscriber management exchange SS, when the central controller CC receives the stop completion report signal e via the interrupt trunk OFT, it releases the communication paths p3 and p4 in the network NW and sets the communication path p5,
A telephone network trunk exchange PT is connected to subscriber n1. Subscriber n1 uses telephone T to send and receive voice information to and from the caller via subscriber management exchange SS and telephone network trunk exchange PT.The call ends γ, and subscriber n1 restores telephone T. Then, a call termination signal g is transmitted to the subscriber management exchange SS.The central control unit CC of the subscriber management exchange SS that received the call termination signal g identifies the termination of the telephone call P, and The communication paths p2 and p5 are released, the on-hold communication path p1 is reset, and a resume request signal is transmitted to the facsimile network storage exchange FS via the interrupt trunk OFT and the facsimile network relay exchange FT.Resume request signal The facsimile network storage/switching device FS that received the
Continuous transmission of image information a is resumed for 1.

Next, in FIGS. 4 and 5, when subscriber n1 is in the middle of a telephone call P, the central control unit CC of the subscriber management exchange SS stores a memory area Ml corresponding to subscriber n1 in the main memory MM. Busy information B is set in response to a telephone call P within the network NW, a call path p6 is set within the network NW, the telephone T and the calling party are connected via the telephone network relay switch PT, and the voice information is f can be exchanged. In this state, when the facsimile call F is received by the subscriber Mn 1, and the facsimile network storage exchange FS transmits the ``C output request i6i'' via the facsimile network relay exchange FT, the central control of the subscriber 1 subscriber exchange SS Device (20 refers to the storage area M1 in the upper storage device t M M, joins: Pinl is telephone call 1)
It identifies that the call is in progress, sets the communication paths p7 and p8 in the network NW, puts the communication path p6 on hold, and makes the telephone call 1) via the interrupt I/rank OFT. For example, a sound facsimile interrupt signal j is transmitted from the sync OF 'I' to the telephone 'r which is currently on a call.
