Description

Description: TECHNICAL FIELD The present invention relates to a call management method in a communication network such as a telephone, and particularly to an independent method when call connection is made over a plurality of independent communication networks. The present invention relates to a method of managing calls across communication networks.

[Conventional technology]

With the opening of public telecommunications business in recent years, it is expected that communication requests from users will often occur across multiple independent communication networks.In such a case, billing to users will occur. As a method, there are some conceivable methods for applying the conventional fee system to the above new communication network. That is, (1) Each business operator individually settles the charge in his or her own communication network and charges the user. (2) Any one of a plurality of operators charges the call end-to-end and the user charges the call, while the other operators charge the operator who charges the user a charge. To do.
(3) A compromise between cases (1) and (2).

By the way, from the user's point of view, the method (1) is often complicated because a charge for one communication is divided into a plurality of bills, and it is considered that the method (2) is preferable. However, in the case of the method (2), there is a problem in the method of processing the charge settlement between the operators. In order to prepare for troubles in the case of charges, it is necessary to collect and store detailed call data for calls that pass through the network even if the communication network does not charge the user. In the event of an emergency, it will be possible to collate individual calls with other carriers based on the stored data. However, in order to store detailed call data, not only a large capacity memory is required, but also the processing time of the processor for data collection cannot be ignored. As one measure for relieving these points, it may be possible to manage only by the number of calls, but it will not be possible to collate for each call in the unlikely event of a charge problem.

Note that regarding charging between communication networks, for example, JP-A-62-530
No. 64 publication is mentioned.

[Problems to be solved by the invention]

As described above, so far, no consideration has been given to efficiently performing fee settlement among multiple telecommunications carriers. It is troublesome for multiple telecommunications carriers to collect detailed data about each call, and not only does it require a large capacity memory for storage, but it also has problems such as affecting the processing capacity of the processor. Is.

It is an object of the present invention to provide a call management method between independent communication networks which enables efficient charge settlement between telecommunication carriers.

[Means for solving problems]

In the independent communication network in which the calling subscriber is accommodated, it is assumed that there is an independent communication network operated by a plurality of different telecommunications carriers. If the incoming dial signal, which includes the corresponding code and the called subscriber number, is received and translated, and the incoming dial signal is identified as not a call to the independent communication network, the call identification is used for the call. Call management number is transferred to the independent communication network of the route indicated by the called dial number together with the called dial number and the calling subscriber number, while the call management number is assigned as a set. , In the independent communication network in which the incoming dial number and the calling subscriber number are transferred and received, the incoming dial number is translated to make a call to an independent communication network other than the independent communication network. Each time is identified, the call management number, the incoming dial number, and the calling subscriber number as the received set are transferred to the independent communication network to the route indicated by the incoming call number while the outgoing call is made. When a call from a subscriber arrives at a called subscriber accommodated in the independent communication network indicated by the called number, a call management station in each of the via independent communication networks involved in call transfer from the calling subscriber, Alternatively, at the billing station, the calling subscriber number required for the later charge adjustment and call verification for the above-mentioned call, using the independent communication network compatible code excluding the own independent communication network compatible code and the call management number as key codes. This is achieved by collecting and storing data including a called subscriber number, a communication start time and a communication end time.

[Action]

When it is identified from the dialed number from the user that the call extends to another communication network, the call is assigned a unique call management number and then transferred to another communication network. It is something like this. The call arrives at the called party directly through another communication network or through one or more other communication networks. At that time, in each communication network related to the call, together with the code of the other related communication network, Since the minimum required data for the call is managed by the call management number, it is possible to easily collate the call later.

〔Example〕

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

First, the relay system according to the present invention will be described.
The figure shows the simplest example. In this example, a case where a call from the subscriber SUB-A accommodated in the communication network A is received by the subscriber SUB-B accommodated in the adjacent communication network B is shown. The operation is shown in FIGS. 3 (a) and 3 (b) to the fifth operation.
The description will be made below with reference to FIGS.

That is, when the subscriber SUB-A goes off-hook, the calling is detected by the subscriber exchange 1 in the communication network A, and
The dial number from the subscriber SUB-A is continuously received. In this example, the dialed number is "00
X ₁ X ₂ −65−4321 ”is dialed, but of these,“ 00X ₁ X ₂ ”is for selecting a communication network, and“ 65-4321 ”is a called subscriber in the selected communication network. It shows the person number. Therefore, when “00 × ₁ × ₂ ” selects the own communication network, that is, the communication network A, the call is received by the called party accommodated in the communication network A by a known method. It is the place to be done.

However, when "00 × ₁ × ₂ " selects the communication network B, the call management number determination device 2 determines the call management number, and at the same time, the line to the communication network B is selected. It has become so. The call management number is a series of serial numbers that are updated by +1 every time a call from the communication network A to another communication network occurs. The call management number "000n" obtained in this way is not Call subscriber number "65-4321",
Furthermore, the calling subscriber number (SUB- extracted from the accommodation position
The subscriber number of A) is added and sent to the communication network B.

Although the call management number for the communication network B is once received by the transit exchange 4, the transit exchange 4 in this example is assumed to have a function of handling end-to-end billing, which is a well-known method. Executes a process of connecting the call to the called subscriber SUB-B via the exchange 7, and collects detailed data on billing using the call management number and the communication network A code as key codes, and then controls by the processor 5. Below, the 4th
As shown in the figure, the data is stored in the memory 6. The detailed record relating to the billing can be easily indexed later by using the key code as an index. For example, the billing from the communication network A operator to the communication network B operator will be described as an example. The communication network A operator collects the calls to the communication network B handled by the communication network A for every certain period. A charge check sheet as shown in FIG. 5 (a) is issued to the carrier of the communication network B. When creating the charge check sheet, the key code including the communication network B code Y ₂ is read and tabulated. That makes it easy to create. On the other hand, communication network B
Since the business operator searches for a key code including the communication network A code Y ₁ and collects it, a billing statement corresponding to the billing statement is created as shown in FIG. 5 (b). It is possible to easily check the correspondence with the bill of payment.

The above is the case of receiving a call to the adjacent communication network.
FIG. 1 shows a connection sequence when a call generated in the communication network A is received via the communication network B to the subscriber SUB-C in the communication network C. Subscriber SUB as shown
Call from -A communication network A in the switching station A ₁ to A _{3, 1} in the switching station B network B .about.B _3, the subscriber SUB via the communication network C in the switching center C ₁ -C ₃
-Called to C, but at that time, the subscriber SU
From B-A example is "00X ₁ X ₂ -Y ₃ -65-4321" is adapted to be dialed. First, "00 X ₁ X ₂ " (= Y ₂ ),
After “Y ₃ ” is dialed as the code of the communication networks B and C, respectively, the called subscriber number “65-4321” in the communication network C is dialed. Exchange A ₃ ,
When C ₁ is the call management station and the exchange B ₁ is the charging station, various signals are exchanged as shown in the figure,
The subscribers SUB-A and SUB-C are connected. By the way, the exchanges A ₃ , B ₁ , and C ₁ each have “0000nY
_The necessary data is stored using “ ₂ Y ₃ ”, “0000nY ₁ Y ₃ ”, and “0000nY ₁ Y ₂ ” as key codes.

When the call is managed in each communication network as described above, only the minimum necessary data needs to be managed in the communication network that does not charge the user.

〔The invention's effect〕

As described above, according to the present invention, there is an effect that the charge settlement between a plurality of electric utilities can be performed economically and efficiently.
