Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for mixing general telephone subscription services and hotline services on the same subscriber line. The disadvantage is that the terminal is occupied and you cannot receive services using regular dials.

SUMMARY OF THE INVENTION The object of the present invention is to eliminate the above-mentioned drawbacks and to mix hotline services and general dialing services on one subscriber line.

For this purpose, in the present invention, in order to enable general dialing service in the conventional hotline system, when the subscriber makes a call, the hotline service is immediately entered and the registered subscriber is called. Instead, we decided to set a certain time limit before entering the hotline service.

That is, the present invention is characterized in that if a subscriber dials within this time limit, the subscriber loses the subscriber class as a hotline and can receive services by regular dialing. .

Therefore, in order to receive hotline service, the registered subscriber is called for the first time after the time limit without dialing within the time limit, which causes a connection delay of 4 to 10 seconds compared to the conventional method. As long as the time limit is set within a reasonable range, there is no practical problem in not only general dialing services but also hotline services.

The present invention will be explained below with reference to FIGS. 1 to 5.

First, FIG. 1 is a block diagram showing the relationship between a joining device and an exchange.

The exchange shown in this figure is a storage program controlled exchange, in which the central controller CC controls the signal distribution device SD and the signal scanning device SC according to a program stored in the memory device M.
N. Controls the outgoing register trunk ORT and the trunk switch frame SWF within the local office via the switch driver SC.

To explain the operation of each device in the hotline service system according to the present invention with reference to this diagram, a signal scanning device SCN detects a call from a hotline joining device, and an outgoing connection is established between the joining device and the calling register trunk ORT. Connection is made on the trunk switch frame SWF within the local office by the switch driver SC, and a dial tone is heard by the joining device.

If the subscribing device dials immediately (for example, within 4 seconds), the dialed digits are received and the other subscriber is called based on the received digits, just like a regular subscriber.

This is a general dial service.

On the other hand, if the time limit has expired, the subscriber other than the hotline subscriber device will hear the busy tone, but if the subscriber is a hotline subscriber, the number of the subscriber who has already been registered is read out from the memory device M. , the other party is called based on that number.

This is a so-called hotline service.

The system according to the present invention described above will be explained in more detail with reference to FIGS. 2 to 5.

FIG. 2 shows part of a state transition diagram commonly used in electronic exchanges.

In this figure, there are five communication path connection patterns 5o-84.
Between the conventional box parts showing the hotline processing (reading dialed digits) part and the analysis part (whether the hotline subscriber or not, whether the call was made within the time limit T, the power of the other subscriber) An analysis unit (indicated by a Δ mark) is involved.

The transition destinations due to each transition factor are shown by solid lines, but A
, B indicates that subscribers A, B are off-hook, and A, B indicate that subscribers A, B are on-hook, TO indicates timeout, DTR indicates dial tone release, H, N indicates whether the analysis result by the analysis department is a hotline or general connection.

Therefore, the communication path connection pattern S.

-84 is empty for subscriber A, receiving dialed digits, and
This corresponds to the states of sending a tone, calling, and talking.

Within these patterns, subscribers A and B are connected under connection control by the originating register trunk ORT, the local trunk IOT, the ringing signal trunk RBT, the ringing trunk RGT, and the busy tone transmission trunk BTT.

Below, the present invention will be explained with reference to FIG. 2.
When a call is detected, the subscriber data LNTLR corresponding to the accommodating position of subscriber A having the data structure shown in FIG.
The subscriber class is analyzed based on the data.

If the data in the data component HOT is "1", it means hotline service is present, and if it is 0, there is no hotline service.

In the case of the conventional hotline service method, if subscriber A's class is hotline, immediately register the registered party's number from the auxiliary block address AUXBA of the subscriber class as shown by the dotted line. A certain data block AUXB2 shown in FIG. 4 is read out, analyzed based on the number HOTBH, and a call is made to the other subscriber. In the system according to the present invention, the calling connection is made in the same way as for an ordinary subscriber.

Here, the difference in processing for general subscribers and hotline subscribers is that the time limit for receiving the first digit from a hotline subscriber is shorter than that for a general subscriber, and is set to 4 seconds instead of the usual 10 seconds. .

This value is set in the time counter TC of the trunk memory ORM corresponding to the outgoing register trunk ORT shown in Fig. 5, and is decremented by 1 every second from the time of call origination by a register timing program that is executed at a 1-second cycle. .

If the first number is received before the time counter TC reaches 0, that is, within the time limit (4 seconds), then the hotline subscriber will receive the same service as a general subscriber.

On the other hand, if the time limit expires without receiving the first digit, the subscriber class is analyzed, and if the subscriber is a general subscriber, the busy tone is sent, or if the subscriber is a hotline subscriber, the hotline service, reads the registered partner number from the data block HOTBN shown in Figure 4,
Based on that number, it is analyzed and a transition is made to subscriber B's calling state.

In this case, the number of digits R received in the trunk memo IJORM has already been
If the value of DC is 1 or more, that is, if even 1 digit is received, even a hotline subscriber is treated as a general subscriber class, and a transition is made to a state in which busy tone is being transmitted.

Although FIG. 2 shows a specific example of only the calling of the subscriber within the own station, it is of course possible to make outgoing connections and other connections using the hotline service.

In order to simplify the explanation, only the inside of the local station is illustrated.

As explained above, in the hotline service system according to the present invention, if the first digit is dialed by the hotline subscriber within a certain time period from the time of the call made by the hotline subscriber,
Even if the subscriber is a hotline subscriber, the subscriber is forcibly provided with general services.

Therefore, according to the present invention, it is possible to accommodate both a general dial service and a hotline service on one subscriber line, making it easy to introduce the hotline service.

Claims (1)

[Claims] In an automatic hotline service system in an exchange that mixes dial-based services and hotline services on 11 hotline subscriber lines, the time limit from the time the call is connected until the first digit is received by the digit receiving device is stored in a memory corresponding to the device. A time counter installed in the data area of the device is used to count, and if the counted value by the counter is less than a certain fixed time period, the service will be provided by general dialing, and if the dog is less than the above fixed time limit, the subscriber will be notified. If the result of the analysis based on the subscriber data corresponding to the accommodation location is that the callee is a hotline subscriber, the hotline service is performed by reading out the pre-registered number of the called party and translating the called party information. Features an automatic hotline service system.
