Abstract

PURPOSE:To eliminate an unnecessary processing and to make rapid a processing time by sending a connecting completing signal to an outgoing call terminal when the signal during the call at an outgoing station is received at an incoming station in case the information is sent to the outgoing call terminal earlier from an incoming call terminal. CONSTITUTION:When an outgoing call terminal 1 calls an incoming call terminal 5, into the signal during the call to show the calling of the incoming call terminal sent to an outgoing station 2 from an incoming station 4 to which the terminal 5 belongs, after a terminal 4 responds, the information to show whether or not the information is generated earlier from the terminal 4 to the terminal 1 is applied. When the information is sent earlier from the terminal 4 to the terminal 1 and the signal during the call is received at the outgoing station 2, the second connecting completing signal is generated to the terminal 1, the first connecting completing signal is generated to the terminal 5 after the terminal 5 responds.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a connection completion signal sending system in an exchange having a data exchange function.

[Conventional technology]

A conventional method for transmitting a connection completion signal will be explained using examples shown in FIGS. 2 and 3. In FIG. 2, 1 is a calling terminal, 2 is a calling station, 3 is a relay station, and 4 is a receiving station.

5 is a called terminal, and 6 is a relay line connecting the stations. Here, in order to call the called terminal 5, the calling terminal 1 performs an operation to call the called terminal 5 by a predetermined method, and as shown in FIG. Relay station 31
The terminating station 4 and the relay line 6 are connected sequentially, and finally the terminating station 4
An incoming call is displayed on the called terminal 5, and at the same time a ringing signal is sent to the calling station 2.

On the other hand, as shown in FIG. 2, when the called terminal 5 responds to the incoming call, the called station 4 sends a first connection completion signal to the called terminal 5 indicating that the line connection has been completed. Ru. Father, as shown in Figure 2, a signal is sent from the receiving station 4 to the calling station 2, informing the calling station 2 that the called terminal 5 has responded, via the relay station 3, and the calling station Q. 2 had sent a second connection completion signal to the calling terminal 1.

[Problems to be solved]

However, a pair of connection completion signals indicating that the connection has been completed are transmitted at different times as described above, and cannot be transmitted to both the calling terminal 1 and the called terminal 5 at the same time. If the called terminal 5 sends information before the calling terminal 1 after receiving the first connection completion signal,
The called terminal 5 waits for a certain period of time until the second connection completion signal reaches the calling terminal 1, or the father checks whether the connection is completed between the two terminals 1 and 5. What is a connection completion signal? It was necessary to send and receive a separate identification signal for confirmation. Therefore, there is a problem that time is lost and unnecessary processing has to be performed at the terminal, which is inconvenient.

[Means for solving problems]

The present invention solves the above-mentioned problems.In an automatic exchange having a data exchange function, when a calling terminal calls a called terminal, the calling terminal is sent from the receiving station to which the called terminal belongs. Add information indicating whether or not to send information from the called terminal to the calling terminal first after the called terminal responds to the out-of-home signal sent to the calling station to which it belongs, indicating that the called terminal is ringing. However, if the called terminal sends information to the calling terminal first,
This system is characterized in that when the calling station receives an out-of-office signal from the receiving station, it sends a connection completion signal to the calling terminal.

〔Example〕

Next, an example thereof will be described with reference to FIGS. 1 to 3.

FIG. 1 is a time chart when the called terminal first sends information when an embodiment of the connection completion signal sending method according to the present invention is applied; The same reference numerals are given to the corresponding parts.

In the method of the present invention, in the calling signal from the called terminal 4,
By adding information indicating whether or not to send information from the calling terminal 1 first after the called terminal 4 responds, it is possible to determine whether the called terminal 4 sends the information first or the called terminal 4 sends the information first. Control is carried out separately for cases in which it does not issue and cases in which it does not.

If the called terminal 4 sends the information first, as shown in Figure 1, when the calling terminal 1 receives an out-of-office signal from the calling station 2, it issues a second connection completion signal, and After the called terminal 5 responds, a connection completion signal of @1 is sent to the terminal 5.

If the called terminal 4 does not send out the information first, just like the conventional case shown in FIG. 3, when the called terminal 5 responds,
First, a first connection completion signal is sent to the called terminal 5, and when a response signal is received by the calling terminal 2, a second connection completion signal 1 is sent to the calling terminal 1.

〔Effect of the invention〕

As explained above, whether the calling terminal first sends out the information after the called terminal responds during the ringing No. 1g, or the
If the incoming call terminal sends out the information first, the calling terminal will receive a connection completion signal when it receives an out-of-office signal at the calling station, and the called terminal will receive a connection completion signal. After the called terminal answers, a connection completion signal is sent out. If the called terminal does not send information first, the connection completion signal is sent to the called terminal when the called terminal answers, and then the call is made. When the station receives a response signal, it sends a connection completion signal to the calling terminal, so when the terminal receives the connection completion signal, it can immediately send out information, which speeds up the processing time. This has the effect that the terminal does not have to perform unnecessary processing and is efficient.

[Brief explanation of drawings]

Fig. 1 is a time chart of connection completion according to the present invention (one embodiment of the No. 7 transmission method is applied, when the called terminal does not send information first; Fig. 2 is a general connection completion signal) A block diagram of a circuit to which the sending method is applied, and FIG. 3 is a time chart diagram of a conventional connection completion method.

Claims (1)

[Claims] In an automatic switching system with a data exchange function, when a calling terminal calls a called terminal, a call is sent from the receiving station to which the called terminal belongs to the calling station to which the calling terminal belongs, indicating that the called terminal is ringing. Information indicating whether or not to send information from the called terminal to the calling terminal first after the called terminal responds is added to the medium signal, and the called terminal sends information to the calling terminal first. In this case, the connection completion signal sending method is characterized in that when the calling station receives a ringing signal from the receiving station, a connection completion signal is sent to the calling terminal.
