SOLUTION: In the case of calling from a portable telephone set 1, a telephone number of a free dial subscriber 6 being a connection object from the portable telephone set 1 is stored once, free-dialing is made to call the free-dial subscriber 6 and then a speech connection between the portable telephone set 1 and the free-dial subscriber 6 is conducted. The relay system conducting control is provided with a voice service device 3 making dialing to the free-dial subscriber 6 in place of the portable telephone set 1 and a host computer 4 controlling the voice service device 3.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone switching system, and more particularly to a telephone switching system suitable for diversified use of telephone terminals. More specifically, the present invention relates to an exchange processing method that enables connection from a portable terminal to a toll-free subscriber.

[0002]

2. Description of the Related Art Conventionally, Nippon Telegraph and Telephone Corporation (NTT)
And long-distance new electric companies have commercialized a toll-free service in which the call receiving side bears the call charge. For example, in the case of NTT, the toll-free number is "012".
The four digits of "0" are followed by a six-digit number identifying the toll-free subscriber, and the caller can dial these digits consecutively to obtain a toll-free telephone number owned by the toll-free subscriber. Can be connected to a line. In addition, the telephone subscriber is connected to the target toll-free subscriber line via the telephone subscriber line and the toll-free service network. Correspondence information, billing information, and the like are centrally managed.

[0003] In the case of a free-dialing call in which the call charge is billed on the receiving side, it is necessary to specify the origin of the call and the destination for the billing process. However, in the case of a mobile phone, at present, it is impossible to recognize the destination, so that the billing process cannot be performed. For this reason, the fact is that toll-free calling from a mobile phone is restricted.

[0004]

As described above, in the conventional toll-free service system, the destination is fixed so that billing processing can be performed on the receiving side. Is regulated.

In recent years, in the mail-order business, the service business, etc.,
The number of toll-free service installations is on the rise, and the number of mobile phone terminal contracts in the telecommunications industry is increasing dramatically.

[0006] Therefore, if a system is realized which enables free dialing from a mobile phone without restriction, the convenience of the mobile phone is particularly improved, and the use of the free dial service is expected to further increase. Is done.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above circumstances, and has as its object to provide a method for enabling connection from a portable telephone whose free dialing is restricted to a free dial subscriber. Is to do.

[0008]

In order to achieve the above-mentioned object, a telephone exchange processing system according to the present invention provides a method for connecting to a toll-free subscriber from a portable telephone whose calling to a toll-free subscriber is restricted. And a relay system that enables

Further, according to the present invention, when a call is made from a portable telephone, the telephone number of the toll-free subscriber to be connected from the portable telephone is temporarily stored, and the toll-free call is made by using the telephone number. A caller, and then a relay system for controlling a call connection between the mobile phone and the toll-free subscriber.

[0010] In the present invention, the toll-free relay system includes voice service means for making a call to a toll-free subscriber in place of a mobile phone, and control means for controlling the voice service means.

[0011]

Embodiments of the present invention will be described below. Since it is currently impossible to make a direct call operation from a mobile phone to a toll-free subscriber, in the embodiment of the present invention, the telephone number of the toll-free subscriber is transmitted to the relay system (10 in FIG. 1). Once stored, the relay system calls the toll-free subscriber (6 in FIG. 1) by making a toll-free call. As described above, a relay system that performs a calling operation to a toll-free subscriber in place of a mobile phone is provided with a nationwide number equivalent to a general telephone capable of making a toll-free call.

Then, after the toll-free subscriber answers,
By interconnecting the mobile telephone (1 in FIG. 1) and the toll-free subscriber (6 in FIG. 1) via the relay system, a call can be made.

[0013]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing the configuration of an embodiment of the present invention. Referring to FIG. 1, in the present embodiment, a mobile phone (including a car, a train, a ship, an airplane phone, etc.)
1 includes a toll-free relay system 10 for calling a toll-free subscriber, the toll-free relay system 10 being installed in, for example, a communication company,
The voice service device (VS-II) 3 and a VS control host computer 4 for controlling the voice service device 3 are provided.

FIG. 2 is a flowchart for explaining the operation of this embodiment. The operation of the embodiment of the present invention will be described with reference to FIGS.

Referring to FIG. 1, since it is impossible to make a direct call from the mobile phone 1 to the toll-free subscriber 6, the toll-free relay system 10 housed in the NTT exchange 2 uses the mobile phone (TEL-A). 1) 1 receives and stores the telephone number of the toll-free subscriber 6 who wants to call (route in FIG. 1). In response to a call from the mobile phone (TEL-A) 1 to the relay system 10, the toll-free relay system 10 prompts for a toll-free number as shown in FIG. 2 (step 201). (TEL-A) Enter a desired toll-free subscriber number from 1 (step 202).

Next, the relay system calls the toll-free subscriber 6 on the route shown in FIG. 1 (step 203 in FIG. 2), and after the toll-free subscriber 6 answers, connects the path in the voice service device 3 to the route. 1 and route 2
Are connected in a loop to enable a call between the mobile phone (TEL-A) 1 and the toll-free subscriber (TEL-B) 6 (step 204 in FIG. 2).

In the above embodiment, the connection path between the portable telephone 1 and the toll-free subscriber 6 is determined by the voice service device (VS).
-II) Although the method performed inside 3 has been described as an example, as another method, for example, as shown in FIG. 3, a PBX (private branch exchange)
7, a connection path may be formed.

[0019]

As described above, according to the present invention,
It is possible to connect to a toll-free subscriber, which is currently increasing, from a mobile phone, which has the effect of significantly improving the convenience of the mobile phone.

The reason is that, in the present invention, the relay system is configured to make an alternative connection to a toll-free subscriber instead of the mobile phone.
