TECHNICAL FIELD OF THE INVENTION
The present invention relates to a free call reception server and a free call communication system using the Internet, and more particularly, to a reception server installed by a company or the like that provides a free call to a customer, to receive a free call from a customer's mobile phone, and to make a callback. A request for a callback call to a callback exchange server that provides a service, a callback of a free call answering telephone of the enterprise from the callback exchange server, and a free call reception server configured to connect to a mobile phone of the customer. And a free call communication system using the Internet.
[0002]
[Prior art]
In recent years, telephone communication services have undergone rapid change and diversification from fixed telephones to mobile telephones and further to Internet telephones (IP telephones) with the dramatic development of related technologies and deregulation. In recent years, telecommunications services have different communication line usage charges and call charges depending on the communication carrier and the communication system and service contents developed one after another.
[0003]
In Japan, in particular, multiple telecommunications carriers are competing with each other due to deregulation, providing a variety of different services such as fixed-line phones, mobile phones, and IP phones. There are many delays in the services provided by domestic telecommunications carriers, and there are large disparities in usage fees between domestic and overseas telecommunications carriers. It is said that the fees of Japanese telecommunications carriers are much higher than those of carriers.
[0004]
Against this background, there is a need for telephone users in Japan to naturally use the services of telecommunications carriers with low usage charges and call paths through telecommunications carriers with low telephone charges. A variety of communication methods have been proposed to respond to such demands. One of them is a so-called callback method in which when making an international call from within Japan, the call is switched to a call from an inexpensive overseas carrier. International calling service is provided. As seen in this international callback system, the field of telephone communication services in Japan has entered the age of international competition with the entry of overseas telecommunications carriers.
[0005]
In the above international callback call, a caller calls an overseas callback communication carrier using an international telephone line, sends necessary information such as a caller's ID and a telephone number of a called party, hangs up the telephone once, and Call-back method was used to wait for a callback from a callback carrier. Calls made by overseas call-back telecommunications carriers use toll-free dials (registered trademark) prepared by the telecommunications carrier, so the caller only has to pay the call charges after being connected to the called party. International calls can be made at cheaper rates based on the telecommunications carrier's pricing.
[0006]
As an improvement of such an international callback communication system, for example, there is a communication system disclosed in Patent Document 1. In the call method disclosed in the above-mentioned literature, a caller connects to a web server of an overseas callback communication carrier from a computer using the Internet, and notifies a caller ID, a telephone number, and a telephone number of a called party, Based on this information, the exchange of the callback communication carrier calls back the caller, calls the called party, connects to the caller, and charges according to the talk time.
[0007]
On the other hand, a service called free dial is provided as one of the telephone communication services conventionally performed. Toll-free calling is a so-called pay-per-call service, in which the caller is not charged and the incoming call is charged. There are many cases where services are set. For example, there are a telephone of a call center for receiving a purchase application for mail order, a telephone of a customer center for receiving complaints and inquiries from customers, and a telephone set up by an insurance company such as an automatic insurance company to receive accident processing.
[0008]
For example, Patent Literature 2 discloses a technology for realizing a function equivalent to this free dial at a low call charge. The technology disclosed in the above-mentioned document refers to a WWW (World Wide Web) homepage provided by a company or the like via the Internet from a customer's PC (Personal Computer) equipped with a microphone and a speaker. By clicking on the telephone script display, a customer PC is connected to a telephone service of a company that has installed a general telephone line, and this technology applies a so-called Internet telephone (IP phone).

[Problems to be solved by the invention]
By the way, the free dial call service for receiving a call from a mobile phone is particularly expensive, and although there is a difference depending on the communication carrier, on average, it is about 10 yen / 14 to 15 seconds, and 40 to 50 yen / min. , 120-130 yen / 3 minutes, etc., and the burden on companies using this service is extremely large. For this reason, there are many companies that set up and operate the free dial service so that incoming calls from mobile phones are restricted and only incoming calls from fixed phones are received. For this reason, in a free call communication system from a mobile phone, there is a demand for a system in which a customer's call charge burden is light and a company can reduce the call charge burden.
[0011]
Since the technology disclosed in Patent Document 2 refers to a WWW homepage from a customer's PC via the Internet, there is a problem that the technology can only be used from a place where a PC and an Internet connection environment are available. In the case of requesting an automatic insurance company to handle an accident, it is desirable that the system be available from a mobile phone owned by the customer. In consideration of the current spread of mobile phones, it is generally necessary to provide a system that allows free calls from mobile phones.
[0012]
