Abstract

PURPOSE:To attain a district investigation system investigating originating call number by district of callers by receiving a telephone number of a caller called from a public network with an electronic exchange and calculating the originating call number by the district based thereon. CONSTITUTION:When a caller telephone number send from an I interface in compliance with the CCITT recommendations is received by a PBX 1, the PBX 1 uses a host computer 3 to retrieve the caller telephone number from a local station data 5 in a database 4. Then the computer 3 retrieves a district corresponding to the local station number sought from the database 4 from a district data 6 and writes the caller traffic unit into an analysis data 7. The retrieval and write in this way are repeated for each reception and the district data 6 of the caller is stored in the analysis data 7. Thus, the called party dose not need to inquire the address and the telephone number for the caller and the originating call number by district are analyzed quickly.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention relates to a regional distribution survey method for investigating the number of calls made by a caller by region by receiving the caller's telephone number on the called side.

[Prior art and its issues 1 Conventionally, the regional distribution survey method used to investigate the number of calls made by callers by region, but because the called party did not know the caller's telephone number, the caller was asked to provide the address and telephone number. This was done by asking questions and compiling the information.

In the conventional regional distribution survey method mentioned above, information on the caller's area was obtained by asking each caller for their address, etc.
There was a problem in that it required manpower and time to analyze and calculate the area for the phone number asked, making the work complicated.

The present invention has been made in view of the above-mentioned problems.
The purpose of the present invention is to provide a regional distribution survey method that makes it possible to easily investigate the number of calls made by callers by region without requiring manpower and time for regional analysis and calculations.

[Means for Solving the Problems] In order to achieve the above object, the regional distribution survey method of the present invention includes a receiving means for receiving a caller's telephone number from a public network using an electronic exchange using the I interface recommended by the CCITT. and a means for calculating the number of outgoing calls by region based on the caller's telephone number received by the receiving means.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of the regional distribution survey method in this embodiment, and FIG. 2 is a block diagram showing the contents of the database.

1 is an electronic exchange (hereinafter referred to as PBX), which connects the caller's line from the public network 2 to the terminal 1a and transmits the caller's telephone number using the CCITT recommended interface (not shown). Receive. 3 is PB
The host computer 4 connected to X1 is a database of the host computer 3, in which area code data 5 and regional data 6 of the area corresponding to the area code are registered. 7 is analysis data for writing the number of outgoing calls by region.

Next, a method for investigating the number of outgoing calls by region will be explained.

■By interface, public network 2
When the PBX 1 receives the caller's telephone number, the PBX 1 sends the caller's telephone number to the host computer 3. The host computer 3 that has received the caller's telephone number stores the caller's telephone number in the database 4.
Search from the area code data 5 within. Then, the host computer 3 searches the area data 6 for the area corresponding to the area code found from the database 4, and writes the number of outgoing calls for each area into the analysis data 7.

Such searching and writing is repeated for each reception, and the sender's local data is accumulated in the analysis data.

According to the above-mentioned regional distribution survey method, the telephone number of the caller is received by the PBX 1, and the host computer 3 analyzes and calculates the number of outgoing calls by region. There is no need to ask for addresses or phone numbers, and the number of outgoing calls by region can be quickly analyzed. Therefore, for example, by calculating the regional distribution of telephone reservations for TV shopping, etc., it can be widely used as study material for customer service, order improvement, etc.

It goes without saying that the contents of the database 4 can be changed depending on the investigation and purpose.

[Advantageous Effects of the Invention 1] As explained above, the regional distribution survey method of the present invention can easily investigate the number of calls made by callers by region without requiring manpower and time for regional analysis and calculation.

Claims (1)

[Claims] Based on the I interface recommended by the CCITT, there is a receiving means for receiving the caller's telephone number from the public network at an electronic exchange, and the number of outgoing calls by area based on the caller's telephone number received by this receiving means.
