Abstract

PURPOSE:To easily identify the number of starting times for respective general exchange stations by giving identification information inherent to respective general exchange stations, adding said identification information with regular subscriber number information which the general exchange stations transmit so as to transmit them to a special exchange station at the time of connecting to the special exchange station different in an operation company. CONSTITUTION:It is assumed that plural general exchange stations 11-13 and the special exchange station 16 connected from the general exchange stations 11-31 through a public network 15 are operated by the different operation companies. When an originating call for the special exchange station 16 is judged at the time of connecting the originating call of the general exchange stations 11-13, identification information given to respective general exchange stations 11-13 are added to subscriber number information so as to transmit them to the special exchange station 16 at the time of transmitting subscriber number information by the general exchange stations 11-13. Thus, the number of starting times for respective general exchange stations 11-13 can easily be identified without using a processor such as a computer in the special exchange station 16.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an additional number sending system, and particularly to an additional number sending system used between exchanges operated by different operating companies.

[Conventional technology]

Traditionally, in the case of exchanges operated by different operating companies, for example, multiple mobile telephone exchanges handling car telephones and an international exchange handling international calls, the operating company of the international exchange exchange would communicate with each mobile telephone exchange via the public network. The number of accesses, that is, the number of activations, is checked, and a fee corresponding to the number of activations is charged to the operating company of each mobile telephone exchange. In this case, since the number of activations must be counted for each mobile phone exchange, the operating company of the international exchange usually uses a computer or other device to process the billing data recorded on the billing magnetic tape installed in the international exchange. When processed by the device, the mobile telephone exchange from which the call was made is determined from the caller number information recorded in the billing data, and the number of activations for each mobile telephone exchange is calculated.

[Problem to be solved by the invention]

As mentioned above, in the conventional system, a processing device such as a computer determines the mobile telephone exchange from which the call was made based on caller ID information, and requires a function for counting the number of activations for each mobile telephone exchange. However, the disadvantage is that the computer program becomes complicated.

SUMMARY OF THE INVENTION An object of the present invention is to provide an additional number sending system that allows the number of activations for each general exchange to be easily identified without using a processing device such as a computer in a specific exchange.

[Means to solve the problem]

The additional number sending method of the present invention is such that each of a plurality of general switching centers and a specific switching center connected from the general switching center via a public network are operated by different operating companies, and when the general switching center is connected for outgoing calls, , when it is determined that the call is an outgoing call to the specific switching center, when the general switching center sends subscriber number information, it adds identification information assigned to each general switching center to the subscriber number information. The configuration is such that the information is sent to the specific exchange.

〔Example〕

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

FIG. 1 shows the structure of identification information according to an embodiment of the present invention, in which called party number information 1 and calling party number information are transmitted from a calling station to a specific exchange, for example, an international exchange. In addition to 2, calling station number information 3 individually assigned to each calling station is included.

FIG. 2 is a diagram for explaining a case in which a call is made from a mobile terminal to an international switching center via a mobile telephone switching center and a public network according to an embodiment of the present invention. In Figure 2, car telephone exchanges 11 to 13, each operated by a different operating company, are public W415
A calling subscriber 14 is shown making a call from a motor vehicle connected to an international exchange 16 of another operating company via a telephone. Each of the mobile telephone exchanges 11 to 13 is given a unique identification number in advance.

The operation will be explained below. The originating subscriber 14 may, for example,
When making an international call via the car telephone exchange 11, the international exchange 16 is accessed via the public w415.
At the time of outgoing connection, the mobile telephone exchange 11 sends the calling station number information 3 previously given to this station to the international exchange 16 in addition to the called party number information 1 and the calling party number information 2. The international exchange 16 receives this information, and based on the calling station number information 3, refers to data registered in advance for identifying the calling station, and determines whether the processed call is originating from the mobile telephone exchange 11. the number of activations of the mobile telephone exchange 11 is added to the already stored data on the number of activations of the mobile telephone exchange 11 and stored in a storage device (not shown), and an instruction to output the number of activations inputted by the maintenance person. The signal outputs charge information along with the number of activations from the corresponding mobile telephone exchange to a terminal (not shown).

In this embodiment, an example of a mobile telephone switching center operated by a different operating company is shown, but a similar configuration can be applied to other switching centers operated by different operating companies, and the number of activations for each calling station can be output.

〔Effect of the invention〕

As explained above, the present invention assigns unique identification information to each general switching center, and when connecting to a specific switching center operated by a different operating company, in addition to the normal subscriber number information sent by the general switching center. Since the configuration is such that this identification information is added and transmitted to the specific exchange, it is possible to easily identify the number of activations for each general exchange without using a processing device such as a computer at the specific exchange. It becomes possible.

Claims (1)

[Claims] Each of the plurality of general exchanges and a specified exchange connected from the general exchange via the public network are operated by different operating companies, and when the general exchange is connected for outgoing calls, the outgoing call to the specified exchange is If it is determined that this is the case, when the general switching center sends subscriber number information, it adds identification information assigned to each general switching center to the subscriber number information and sends it to the specific switching center.
