CONSTITUTION:The system consists of a network service control circuit 100, exchanges 200-203, telephone sets 300-304 and a common line signal network 400. Since the network service controller 100 has a registration area for common utility to record a telephone number of a transfer destination in the order of first-come up to a prescribed capacity for a decided time corresponding to the subscriber telephone number, the telephone subscriber uses the transfer destination number registration area of the common utility as required to collect the utility charge from the telephone set during communication immediately in the case of registration or revision. Thus, the transfer service is realized without advanced contract of the service, installation charge and the basic charge or the like.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention enables all telephone subscribers, when necessary, to use a shared forwarding number registration area provided in a network service control device. The present invention relates to a telephone transfer method that allows immediate telephone transfer service without having to sign a service contract in advance.

[Conventional technology]

Telephone subscribers can receive forwarding services by installing a terminal with a forwarding function, operating the terminal, setting a forwarding destination number, etc., and having it perform the forwarding, or by using a service provided by a telecommunications company. A method has already been implemented in which a user subscribes to a telephone forwarding service and registers the forwarding destination number etc. in the subscriber data of an exchange by dialing from a telephone.

[Problem to be solved by the invention]

The method using a terminal requires the customer to purchase or rent a terminal, and the method of subscribing to a telecommunications company's service also requires the installation of control memory for the subscriber, so there are installation fees at the time of subscription and monthly fees. The customer was required to pay a fixed basic fee. For subscribers who use these services frequently over a long period of time, there is no particular problem with these existing services, but for customers who want to use them for a short period of time or customers who only occasionally want to use them a few times a year, the existing services may not be sufficient. The disadvantage of this service was that it was not possible to use it because the usage fee per session was relatively high.

The present invention allows the transfer destination phone number to be changed to correspond to the subscriber phone number.
A network service control device is provided in the public network that has a shared registration area that can record up to a certain amount of data on a first-come, first-served basis for a predetermined amount of time, and telephone subscribers can use the shared forwarding number registration area when necessary. This makes it possible to immediately collect usage fees for registrations and changes from the communicating phone, allowing transfers to be made without the need for prior service contracts, construction fees, basic fees, etc. The purpose is to provide a telephone transfer method that allows users to receive services.

[Means to solve the problem]

In order to achieve the above object, in the present invention, a network service control device having a transfer destination registration area is provided in a public communication network.

[Operation] When a certain first subscriber requests the network service control device to register the forwarding destination telephone number of the subscriber via the exchange, the network service control device accepts the request. When a second subscriber inquires about the first subscriber's call forwarding destination via the exchange after registering in the transfer destination registration area, the network service control device does not accept the request. The first subscriber's telephone forwarding destination is checked by referring to the area, and if any, it is returned to the exchange, and the exchange connects the second subscriber to the telephone of the forwarding destination telephone number.

FIG. 4 is an explanatory diagram showing an example of the configuration of a transfer destination number registration area for shared use in the network service control device 100.

In the figure, reference numeral 110 indicates an expanded tree of the last five digits of the telephone number. 120 is a joint registration area (
This means that there are N joint registration areas for subscribers whose telephone numbers have different first three or four digits. N
The value of can be set variably depending on the usage situation.

), 130 is the registration area for one subscriber, 131 is the upper 3 or 4 digit number registration area, 132 is the destination phone number registration area, 133 is the password registration area, and 134 is the valid time registration area. Show area.

Next, the operation will be explained with reference to FIGS. 1 to 4.

First, the transfer destination registration operation will be explained. In FIG. 1, subscriber A is a customer who subscribes to telephone 300. In FIG. When subscriber A travels for business, if subscriber A knows in advance that the destination telephone number is Y, subscriber A dials dial information 500 from telephone 300 and enters the transfer destination telephone number. Register Y. If you want to change the forwarding destination at the destination, also register the PIN number. Also, if you want to make the valid time variable (for example, if you omit the valid time, you can decide that it is valid for a certain period of time, and then specify it only if you need more than that).
The valid time is also registered.

The exchange 200 that receives the dial information 500 detects the telephone number X of the subscriber A, collects a signal of the exchange information 600 from the dialed information, and sends it to the network service control device 100.

The network service control device 100 uses the last five digits of the registered subscriber telephone number X to obtain the joint registration area 120 from the expansion tree 110 shown in FIG. Next, joint registration area 1
20 and if there is a vacant area, obtain the registration area 130 for one subscriber, and enter the upper three digits of phone number 8 digits (including 8 digits) or 4 digits (when X is 9 digits).

Record the forwarding destination phone number Y, PIN number, and expiration time.

If the same subscriber has already registered, 1. Instruct the exchange 200 to notify the user of the already registered information, and after receiving confirmation, 1.
Columns 2, 133, and 134 can be rewritten with new information.

If the registration is successful, the network service control device 10
0 calculates the registration fee and exchange information 60
1 is edited and sent back to the exchange 200. If the joint registration area 120 is already used by N subscribers, a signal indicating that registration is not possible is edited into the communication information 601 and sent back to the exchange 200. Exchange information 6
When the exchange 200 receives the 01 signal, when the registration is completed, it collects the registration fee along with the call fee and provides guidance to the effect that the registration is completed.

If registration is not possible, we will provide guidance to the effect that registration is not possible.

Next, the operation of transfer connection will be explained. In Figure 1, when subscriber B wants to contact subscriber A by phone, subscriber B is informed in advance by subscriber A that subscriber A will use a shared forwarding service when he is absent. , or if it is known by habit, when subscriber B learns that subscriber A is absent, subscriber B dials the service identification code (IXzYz) shown in dial information 501 and telephone number X from telephone 301.

Exchange 201 that received the dial information 501
edits the transfer timing signal of the exchange information 602 from the received information and sends it to the network service control device 100 in response. The network service control device 100 obtains a joint registration area 120 using the last five digits of telephone number The registration area 130 of the subscriber with the matching four-digit number is obtained.

Next, when the destination phone number Y is obtained from area 132 in the registration area 130, the exchange information 603 is edited as a timing result signal indicating that transfer is possible and that the number is Y. , and returns it to exchange 201. The exchange 201 then performs a normal connection using the telephone number Y and receives the call to the telephone 303.

On the other hand, if the joint registration area 120 is checked and there is no subscriber whose top three or four digits of telephone number X match, or if the number matches but there is no record of the forwarding destination in area 132. The exchange information 603 is a transfer not possible signal.
is edited and sent back to exchange 201. The exchange 201 thereby provides guidance that there is no record of the transfer destination.

The operation when changing the transfer destination at the destination will be explained. 1st
In the figure, when subscriber A changes his destination from telephone 303 to telephone 304, subscriber A changes his destination from telephone 303 to telephone 304.
1!303, or the telephone 304), the service identification code (I!
X3Y3), joint registration area phone number (corresponds to X in Figure 1), changed destination phone number (corresponds to Z in Figure 1), PIN number at the time of registration, and extension if you wish to extend the validity period. Dial the time (optional).

Exchange 202 that received the dial information 502
edits a signal of exchange information 604 from the received information and sends it to the network service control bag W100.

The network service control device 100 uses the last five digits of the telephone number X to obtain the joint registration area 120 from the expansion tree 110 in FIG.
The registration area 130 of the subscriber whose telephone number X has the same upper three digits (in the case of eight digits including the area code) or four digits is obtained. Next, it is checked whether the password recorded in the registration area 133 and the received password match, and if they match, the destination telephone number is changed from Y to Z. If a valid time is attached, time extension processing is performed on the area 134.

If the change processing is possible, the exchange information 605 as a signal indicating that the change is possible is edited and sent back to the exchange 202,
Upon receiving this, exchange 202 collects the registration fee in accordance with the call fee, and provides guidance to the effect that the change has been made. On the other hand, in the network service control device 100,
If there is no registration area for the corresponding subscriber or if the password numbers do not match, the exchange information 605 is edited and sent back to the exchange 202 as a signal indicating that changes are not possible. In this case, the exchange 202 provides guidance to the effect that the change cannot be made.

A method of controlling the effective time will be explained. If the customer has omitted specifying the validity period, one possible method is to make it valid for a certain period of time. In addition, for customers who require more time, it is effective to have them specify it by varying it within a certain limit. In either of these cases, the network service control device 1
In 00, the valid time of the joint registration area 134 is checked at regular time intervals, and the valid time is subtracted in order at each check, and when the valid time reaches 0, the registered area 134 of the subscriber is checked.
Performs control to clear 0. The valid time can also be extended when the forwarding destination number is changed, but in this case, the valid time can be extended by adding it to the already registered valid time.

In this embodiment, a detailed configuration example is shown for subscriber dial information, message configuration exchanged between the exchange and network service control device, and configuration of a shared transfer number registration area. It is clear that the present invention can be implemented in various other ways.

For example, it is clear that in addition to IXY numbers, 0OXY numbers for identifying other companies, specific telephone numbers, vacant long-distance numbers, etc. can be used as the service identification code.

In addition, the method for configuring the joint use transfer number registration area is shown as an example of expanding the last 5 digits of the phone number, but there are also methods such as expanding using the upper digits or selecting and expanding specific digits. It is obvious that this is possible. Furthermore, although the exchange of messages between the exchange and the network service control device is realized using a common signal network, it is clear that it can be similarly realized using a packet network or a dedicated data network.

〔Effect of the invention〕

As explained above, in the present invention, by providing a shared registration area in the communication network in which forwarding destination telephone numbers can be recorded on a first-come, first-served basis up to a certain capacity for a predetermined time and according to subscriber telephone numbers. , when a subscriber registers or changes a forwarding destination phone number, the usage fee is immediately collected from the phone that is communicating, so there is no need to pay a pre-service contract, construction fee, basic fee, etc. Another advantage is that it can provide call forwarding services to all telephone subscribers.

Furthermore, the present invention is also effective in securing communication means in the event of a telephone office failure. In other words, if a telephone exchange becomes unable to communicate due to fire or flood damage, satellite telephones, car telephones, etc. are provided as alternative means, but these alternative means are not suitable for making calls. is valid, but
Since the telephone number for incoming calls changes, there is a problem in that continuous service using the same number is not possible, and improvements have been requested.

The present invention is achieved by reserving a part of the jointly used registration number area for disasters (for example, reserving several numbers of members in a joint registration area where N members can be registered) for disasters.
In the event of a disaster, if you register the area/city code of the affected station in 131 of the 130 registration areas (in such a case, you can obtain disaster information and register it all at once using a command etc. using the network service control device). (conceivable), alternative means such as satellite subscriber phone number, car phone number, etc., as explained in the number change registration operation of the present invention (satellite subscriber phone number, car phone number, etc. is the forwarding destination phone number) 2, and the phone number X in the joint registration area corresponds to the phone number used before the disaster). For information on the need for a service identification code,
(In the event of a disaster, there are methods such as providing information through mass media such as television and radio, and notification from the originating switchboard that detects incoming calls to the disaster-affected station, etc.), and the telephone number can be used as before the disaster. , it can be seen that it is also effective in securing means of communication in the event of a disaster.
