Description

Automatic notification of billing information of electronic exchange

The present invention relates to a method for automatically notifying billing information of an electronic switchboard, and in particular, at a time point when a call between calling and receiving subscribers is terminated, charging from an operator position system (hereinafter abbreviated as OPS) to a calling subscriber. The present invention relates to an automatic notification method for billing information that enables automatic notification of information.

Typically, when any calling subscriber wants to talk to a called party located in another country's exchange in an electronic switchgear such as DTS-2000, the calling party calls OPS, aka information desk, and then calls the calling party's phone. When the number is notified, the OPS calls the receiving party of another country and establishes a communication path between the calling party and the receiving party of the foreign country so that the call can be made between the two parties.

At the end of the call between the originating / receiving subscribers, if the caller wants to know the talk time and the call rate, the calling subscriber inquires the charging information to the OPS. The OPS, which has been inquired about the billing information, collects the billing information and sends the billing information to the calling subscriber who terminated the call or prints the billing information to the printer. If an error occurs in the printer, the billing information is provided in the OPS. Stored in memory.

Conventionally, the charging information is notified to the calling subscriber only when the calling subscriber turns to the OPS at the time when the call between the calling subscriber and the called subscriber of the foreign exchange ends. However, there was an inconvenience in that the calling subscriber should contact the OPS every time the call was terminated in order to be notified of the charging information.

The present invention has been made to solve the above-mentioned problems, the purpose is that the calling subscriber and the recipient of the foreign country makes a call using the OPS, and when the call is terminated, the charging information from the OPS to the outgoing subscriber The present invention provides a method of automatically notifying billing information so as to automatically notify the user.

In order to achieve the above object, the automatic notification method for charging information of the OPS according to the present invention comprises the steps of: determining whether a call between calling / incoming subscribers is terminated in an operator location system; Collecting charging information on a call time and a call charge between calling and receiving subscribers at the end of the call; After collecting the charging information, requesting call setup from the operator location system to the calling subscriber; Establishing a call path between the OPS and an originating subscriber by the call establishment request; And informing the charging information to the calling subscriber through the call path in the OPS.

Hereinafter, with reference to the accompanying drawings will be described in detail the configuration and operation of the present invention.

1 is a block configuration diagram to which the charging information automatic notification method of an electronic switching system according to the present invention is applied, and includes a calling terminal 10, a switching unit 20, an OPS 30, and a receiving terminal 40 of another station. Include.

The calling terminal 10 is a terminal owned by a fixed subscriber, and is a specific digit number for a call connection with the OPS 30, for example, a specific digit " to make a call with a subscriber owning the called terminal 40 located in another country. Dial 7 ". The specific digit number dialed by the calling terminal 10 is entered into the exchange 20.

The exchange 20 translates the number of the specific digits transmitted from the calling terminal 10 to form a call path to the OPS 30, and then connects with the OPS 30, and receives the call using the connected OPS 30. By forming a call path with the terminal 40, a call is controlled between the subscribers having the calling / receiving terminals 10 and 40. The exchanger 20 includes a subscriber line processor 21 (hereinafter abbreviated as SLP) 21 and a switching and number translation processor (hereinafter referred to as SNP) as shown in detail in FIG. 23 and a trunk line processor (hereinafter, abbreviated as TLP) 25 are provided.

The SLP 21 is a line processor that manages outgoing / incoming subscriber call processing that owns the outgoing / receiving terminals 10 and 40. The SLP 21 transmits a specific digit number dialed from the outgoing terminal 10 to the SNP 23 for the number. It controls to translate, and controls to form a call path with the calling terminal 10 by requesting the call setup to the OPS 30 according to the number translation result of the SNP 23. In addition, when the SLP 21 is input by the OPS 30 that receives the telephone number for the called terminal 40 notified of the voice from the calling subscriber who owns the calling terminal 10, the SLP 21 transmits the number to the SNP 23 to translate the number. Control to form a call path between the OPS 30 and the destination terminal 40 by requesting the call setting to the destination terminal 40 through the TLP 25 according to the number translation result. The SLP 21 receives the connection key control signal for the call setup request between the caller / caller terminals 10 and 40 from the OPS 30, and the caller terminal 10, the OPS 30, and the other station caller terminal 40. ) Releases only the call path to the OPS 30 from the connected call path, and controls to form a direct call path between the calling / receiving terminals 10 and 40.

The SNP 23 is a processor for performing switching network control and number translation, and according to the number translation request sent from the SLP 21, a specific digit number corresponding to the OPS 30 and a telephone number corresponding to the called terminal 40 It translates, and transmits the outgoing relay occupancy request by the result of translating the telephone number corresponding to the called terminal 40 to the TLP (25).

The TLP 25 is a processor that handles most of outgoing line call processing and performs signal information receiving processing and control for transmitting and receiving signals between stations. The TLP 25 receives outgoing call occupancy request transmitted from the SNP 23 through the SLP 21. The SNP 23 requests a switch connection to the SNP 23 to form a call path with the SNP 23, and transmits a call setup request transmitted from the SLP 21 to the destination terminal 40.

The OPS 30 is a system for forming a call path between the caller terminal 10 and the destination terminal 40 of another country. First, the OPS 30 forms a call path with the caller terminal 10 and then the caller terminal. According to the telephone number corresponding to the called terminal 40, which is notified by voice from 10 and transmitted through the switch 20, a call path between the OPS 30 and the receiving terminal 40 of another station is formed. Next, the OPS 30 transmits a connection key input signal for connecting the caller / caller terminal 10 and 40 to the exchanger 20 to form a call path between the caller / caller terminal 10 and 40. .

With reference to the flowchart of FIG. 2, the setting of the call route between the calling terminal 10 and the OPS 30 according to the present invention having the above-described configuration will be described in detail.

First, the SLP 21 of the switch 20 hooks off the transmitter / receiver of the calling terminal 10 to talk to the called subscriber who owns the other terminal 40 from the calling subscriber who owns the calling terminal 10. It is determined whether the signal and the input signal for the specific digit number using the key input unit are transmitted (step 200).

The SLP 21 controls the number translation by transmitting a specific digit signal transmitted from the calling terminal 10 to the SNP 23 (step 201).

The SNP 23 number-translates the specific digit signal transmitted from the SLP 21, and then transmits the number translation result message to the SLP 21 (step 202).

The SLP 21 requests call setup to establish a call path with the OPS 30 by the number translation result message sent from the SNP 23 (step 203).

OPS 30 notifies SLP 21 of call setup response message to perform call setup in response to call setup request from SLP 21 (step 204).

The SLP 21 receives the call setup response message sent from the OPS 30 and notifies the call setup response message to the calling terminal 10 so that a call path is formed between the calling terminal 10 and the OPS 30. (Step 205).

With reference to the flowchart of FIG. 3, the setting of the call path between the OPS 30 and the foreign terminal 40 in accordance with the present invention having the above-described configuration will be described in detail.

While the calling terminal 10 and the OPS 30 are in a call, the OPS 30 receives the telephone number for the called terminal 40 notified of the voice from the calling terminal 10 and then connects with the receiving terminal 40 of another station. In order to press the telephone number of the destination terminal 40 to transmit to the SLP 21 (step 300).

The SLP 21 transmits the telephone number corresponding to the foreign destination terminal 40 transmitted from the OPS 30 to the SNP 23 so that the number can be translated, and according to the result of the number translation, a call tone terminal ( 10), and a call setup request is made to the TLP 25 so that a call path with the other station destination terminal 40 can be established (step 301).

The TLP 25 requests call setting to the other station receiving terminal 40 so that a call path is established with the other station receiving terminal 40 by the call setting requested by the SLP 21 (step 302).

The other station destination terminal 40 notifies the TLP 25 of the call setup response message to perform call setup in response to the call setup request from the TLP 25 (step 303).

The TLP 25 notifies the OPS 30 of the call setup response message transmitted from the other destination terminal 40 to the OPS 30 through the SLP 21 to establish a call path between the OPS 30 and the other destination terminal 40. The state becomes a heavy state (step 304).

With reference to the flowchart of FIG. 4, the setting of the call path between the calling terminal 10 and the other terminal 40 in accordance with the present invention having the above-described configuration will be described in detail.

During the connection between the calling terminal 10 and the OPS 30 and between the OPS 30 and the destination terminal 40, the OPS 30 establishes a call between the calling subscriber and the destination terminal 40 owning the calling terminal 10. The connection key for making a call between the owned subscribers is transmitted to the SLP 21 (step 400).

The SLP 21 releases only the call path from the call path to which the calling terminal 10 and the OPS 30 and the foreign destination terminal 40 are connected to the OPS 30 by the connection key signal provided from the OPS 30, and sends the call. A direct call path is formed between the terminal 10 and the destination terminal 40 of another station (step 401).

A call path is formed between the calling terminal 10 and the called terminal 40 of another station, thereby making a call state between the calling / called subscribers (step 402).

With reference to the flowchart of FIG. 5, the charging information automatic guidance method from the OPS 30 by the present invention which has the above-mentioned structure to the originating terminal 10 is demonstrated in detail.

The OPS 30 determines whether the call has ended between the calling / receiving terminals 10 and 40 (step 500).

When the call between the calling / calling terminals 10 and 40 is terminated, the OPS 30 collects charging information about the talk time and the call charges talked between the calling / calling terminals 10 and 40 (step 501).

After collecting the charging information, the OPS 30 requests call setup to the calling terminal 10 through the SLP 21 (step 502).

The SLP 21 forms a call path between the OPS 30 and the originating terminal 10 in response to a call setup request from the OPS 30 (step 503).

After the call path is formed, the OPS 30 notifies the calling terminal 10 of the charging information, which is the talk time and the call fee, through the SLP 21 (step 504).

In the present invention described above, the OPS collects the charging information when the call is in progress at the end of the call between the calling subscriber and the destination subscriber in another country, and then automatically informs the calling subscriber of the charging information, thus providing detailed information about the call. There is an effect that it is possible to conveniently inform the talk time and call charges that are billing information.
