Abstract

PURPOSE:To automatically generate a call for a reguired opposite subscriber at time when the subscriber requests by giving a memory for storing call generation information which the subscriber requests and a program controlling the memory in an exchange. CONSTITUTION:The exchange always supervises time and reads designated time when the subscriber A who is previously stored in the storage means intends to make a call and the telephone number of the opposite party B. When it comes to designated time, an incoming subscriber having the telephone numbers of the subscriber A and the opposite party B is acquired and he is called. Thus, the call for the opposite subscriber B required at time when the subscriber A requests can automatically be generated and the subscriber A has to only wait for a return call from the exchange without always worrying about time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention initiates a call from a subscriber housed in a program-controlled exchange to a designated destination number at a time designated by dialing in advance. Concerning time-specific call system.

[Conventional technology]

Conventionally, when a call from a subscriber encounters a call from a subscriber who is busy, the switch automatically or by dialing a special code from the subscriber called the camp-on method, which is similar to this system. [Problem to be solved by the invention] In the camp-on method described above, when a call is busy, It simply waits until both subscribers are free when encountered and reinitiates the call. Therefore, although it is convenient when you want to contact the other subscriber immediately, it is not possible to specify the time at which the call is to be made, so when you want to make a call to a specific subscriber at a specific time. I had no choice but to make the call myself at that time.

An object of the present invention is to automatically make a call to the required destination subscriber at the time requested by the subscriber, and to allow the subscriber to receive a call back from the exchange without worrying about the time. The purpose is to provide a time-scheduled call system that requires only waiting.

[Means to solve the problem]

The time-selected call system of the present invention is a time-selected call system in which a call service is provided at a time specified by a dial from a subscriber accommodated in a storage program controlled exchange, in which the exchange constantly monitors the time. At the same time, the subscriber reads out the designated time and telephone number of the called party which are stored in advance in the storage means, and when the designated time comes, the subscriber and the called subscriber having the called telephone number are read out. This is a configuration that captures and calls.

Further, if it is necessary to capture the called subscriber in advance after capturing the subscriber, a paging signal is sent to the subscriber after capturing the called subscriber, and the capture of the called subscriber is carried out in advance. When there is no need to do so, the calling signal may be immediately sent to the subscriber.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing the flow of registration and execution processing for a time-specific call according to an embodiment of the present invention, in which subscriber B of the other party
An example is shown in which subscriber A is accommodated in the same exchange as subscriber A who wishes to request registration of a time-specific call.

In the registration operation, subscriber A dials a code indicating registration for a timed call after making a call. When the exchange recognizes this code, it sends out an acceptance tone indicating that it is ready to receive future registration data. Subscriber A listens to this and dials subscriber B's telephone number and the time at which he wishes to make the call. The exchange checks the normality of the number and specified time, and if normal, performs registration processing and then sends a confirmation tone to subscriber A. On the other hand, if the called party's telephone number or time is not correct, a rejection tone is sent to subscriber A and the registration process is not performed. To perform the activation, first subscriber A is acquired, and then subscriber B is acquired. If subscriber A cannot be captured because subscriber A is busy, execution of the service is stopped, but if subscriber B cannot be captured, the service is repeated from capturing subscriber A a predetermined number of times. When both subscribers are successfully captured, a paging signal is sent to subscriber A. When subscriber A answers, a ringing tone is sent to subscriber A and a ringing signal is sent to subscriber B. If subscriber B responds, a normal conversation is established. It is also possible to adopt a system in which subscriber B is not captured before subscriber A is called, but subscriber B is captured after subscriber A responds and then called. If subscriber B is accommodated in another exchange, it may be difficult to acquire it in advance due to the signaling system, etc. In this case, after subscriber A is acquired, subscriber B's status is checked and the acquisition is performed. This is to match this even in the case of the same exchange.

Next, the processing procedure at the time of registration will be explained with reference to FIG.

First, the exchange receives dialing information from subscriber A, and determines whether subscriber A is a subscriber authorized for time-selected call service (step 10). Next, if the subscriber is determined to be an approved subscriber, an acceptance tone is sent out (step 11), and if the subscriber is judged to be an unauthorized subscriber, a rejection tone is sent out (step 12). Then, the normality of the dialed destination telephone number is checked (Step 13), and if it is normal, the normality of the time is further checked (Stella 114). Both Steps 13 and 14 are determined to be normal. In this case, the subscriber A must acquire a dedicated memory (Step 16), set the necessary information, and then register it in the queue for each time (Step 17) and send a confirmation tone to subscriber A. Vp18),
Finish the process. If Ste.7113 and 14-11
If any of the deviations is determined to be abnormal, a rejection tone is sent to subscriber A (steps 15 and 19).

Figure 4 shows the contents of the dedicated memory, including forward chain linkage information, reverse chain linkage information,
Information such as requesting subscriber information, destination subscriber telephone number, call origination time information, and number of repeated calls is included. As shown in FIG. 5, these dedicated memories together with a head table having pointers pointing to the first and last dedicated memories and the number of registrations at that time constitute a bidirectional chain queue for each time.

FIG. 3 is a flowchart showing a processing procedure for call origination information taken out from the queue at a designated time. First, an attempt is made to capture subscriber A (step 20);
If acquisition fails, the dedicated memory is released and the process ends. If the acquisition is successful, it is then determined whether to acquire subscriber B before calling subscriber A (step 2).
1).

If pre-acquisition is necessary, attempt to acquire subscriber B (step 22), and after success, call subscriber A (step 23).
), and after the response, calls subscriber B (step 24). Then, in response to subscriber B's response, the dedicated memory is released and a transition is made to a normal conversation state.

On the other hand, if pre-acquisition is not required, subscriber A is called (step 25), and after the response, an attempt is made to acquire subscriber B (step 26). If it can be captured, step 2
Proceed to step 4 and perform the same process thereafter. If subscriber B cannot be captured, send a busy tone to subscriber A (step 27), release subscriber A (step 28), Check whether the specified number of calls has been made (Step 2). If the specified number of calls has been completed, the dedicated memory is released and the process is terminated. If it is not completed, the process is restarted after waiting for a predetermined timing (Step 30). ). At this time, if subscriber A has already called and is in a response state, after transmitting the busy tone to subscriber A, the above-described processing is performed after waiting for disconnection.

When subscriber B is accommodated in another exchange, pre-acquisition is possible only if the subscriber B has a signaling system that allows the status check and acquisition of the other subscriber. , after calling subscriber A, will originate a call to subscriber B.

For example, MF C (Multi-Frequency
This system can be applied across exchanges by using the Compelled) signaling system or the common channel signaling system.

Further, subscriber A can cancel the registered contents before the specified time. In this case, after making a call, subscriber A dials a dedicated code to stop execution of this service. After the exchange receives this and checks that the corresponding subscriber is registering for the service, it releases the dedicated memory and sends a confirmation tone to subscriber A.

〔Effect of the invention〕

As explained above, the present invention has a memory for storing the call origination information requested by the subscriber in the exchange and a program for controlling the memory, so that the call origination information required by the subscriber at the time requested by the subscriber is calls can be made automatically, without having to worry about the time of day for the subscriber.
This has the effect that it is only necessary to wait for a call back from the exchange.
