Description

  The present invention relates to an incoming call rejection service providing system for rejecting a nuisance call.

In recent years, nuisance calls such as sales and solicitation have increased rapidly. Conventionally, attempts have been made to prevent such unwanted calls.
Non-Patent Document 1 describes an outline of “nuisance call service” as an example of countermeasures against nuisance calls provided by NTT. This annoying phone call service is a simple registration operation that is performed immediately after a subscriber receives a nuisance call. ○ △△△ ×××× (subscriber's phone number). This service cannot be accepted. Please note that this service is set to respond with a voice message. This annoying phone call service is particularly effective for annoying phone calls that are repeatedly made from the same phone number.

FIG. 8 is a diagram showing an incoming call rejection service providing system in a comparative example.
The incoming call rejection service providing system 1A of the comparative example is a service provided to each user A to N by a communication carrier. The incoming call rejection service providing system 1A is realized by an exchange 10 installed in a network of a communication carrier. Telephone terminals 40a to 40n are connected to the network of the communication carrier. The telephone terminal 40a is owned by the user A. The telephone terminal 40b is owned by the user B. The telephone terminal 40c is owned by the user C. Similarly, the telephone terminal 40m is owned by the user M. The telephone terminal 40n is owned by the user N. Hereinafter, when the telephone terminals 40a to 40n are not particularly distinguished, they may be simply referred to as telephone terminals 40.

The exchange 10 stores an incoming call rejection list DB (Database) 22. This incoming call rejection list DB 22 is stored together with a list of incoming call rejection telephone numbers registered by each user. In the incoming call rejection list DB 22, the incoming call rejection telephone numbers registered by the users A to N for each telephone terminal 40 are registered as a database in association with the identifiers of the respective users. In FIG. 8, the incoming call rejection list DB 22 is shown under the telephone terminals 40a to 40m.
Since the user N has newly made a connection contract with the communication carrier, it indicates that no incoming call rejection number has been registered yet.

FIG. 9 is a flowchart showing incoming call rejection registration / cancellation processing in the comparative example.
For example, the user of the telephone terminal 40 starts the incoming call rejection registration / cancellation process by answering a nuisance call and then temporarily ending the call and dialing a predetermined incoming call rejection registration number (eg, “144”). Can do. When the exchange 10 detects a call from the contractor of the incoming call rejection service, it starts incoming call rejection registration / cancellation processing.
In step S20, the exchange 10 determines whether or not the telephone terminal 40 has detected a call to a registration number for rejecting incoming calls. The exchange 10 performs the process of step S21 when the condition is satisfied (Yes), and performs the process of step S27 when the condition is not satisfied (No).

In step S21, the exchange 10 is in a state of waiting for a dial operation of the telephone terminal 40. If the exchange 10 detects a registration operation (for example, 2 dial), it performs step S22. If it detects a release operation (for example, 9 dial), it performs step S23 and detects on-hook. If so, the process of step S24 is performed.
In step S22, the exchange 10 registers the telephone number of the telephone terminal 40 that has just made a call to the telephone terminal 40 in the incoming call rejection list DB 22. When the process of step S22 is completed, the exchange 10 returns to the process of step S21.

In step S23, the exchange 10 cancels all registered telephone numbers from the incoming call rejection list DB 22. When the process of step S23 is completed, the exchange 10 returns to the process of step S21.
In step S24, the exchange 10 performs the call disconnection process and ends the process of FIG.

  In step S27, the exchange 10 performs line connection processing, starts calling, and ends the processing in FIG.

FIG. 10 is a flowchart showing call control processing in the comparative example.
When the exchange 10 detects a call signal from the telephone terminal 40, it starts a call control process.
In step S30, the exchange 10 determines whether the call is for a call rejection service contractor. The exchange 10 performs the process of step S31 when the condition is satisfied (Yes), and performs the process of step S37 when the condition is not satisfied (No).
In step S31, the exchange 10 checks the caller telephone number against the incoming call rejection list DB22. That is, the exchange 10 collates the telephone number on the calling side with the incoming call rejection list associated with the telephone number on the receiving side of the call signal.
In step S32, the exchange 10 determines whether or not the originating telephone number is in the incoming call rejection list associated with the incoming telephone number. The exchange 10 performs the process of step S36 when the condition is satisfied (Yes), and performs the process of step S37 when the condition is not satisfied (No).
In step S36, the exchange 10 automatically responds to the calling side telephone terminal 40 with a voice message indicating that the incoming call has been rejected, and ends the processing in FIG.
In step S37, the exchange 10 performs line connection processing to the telephone terminal 40 on the receiving side based on the call signal on the calling side, starts calling, and ends the processing in FIG.

The present embodiment described above has the following effects (A) to (D).

(A) The upper layer incoming call rejection service contractor can prevent annoying calls related to the upper layer incoming call rejection list only by contracting with the service without any operation.

(B) Even if a nuisance call has not been made to an upper-layer incoming call rejection service contractor, it is possible to prevent an unwanted call related to the list based on the upper-layer incoming call rejection list.

(C) The higher-layer incoming call rejection service contractor corresponds to either the upper-layer incoming call rejection list or the incoming call rejection list registered by itself by further contracting the incoming call rejection service and registering a predetermined telephone number. Incoming calls from the telephone terminal 40 can be rejected.

(D) The incoming call rejection service and the upper layer incoming call rejection service are services managed separately from each other. Therefore, the communication carrier can provide the user with the incoming call rejection service and the upper layer incoming call rejection service as separate paid services.

(Modification)
The present invention is not limited to the above-described embodiment, and can be modified without departing from the spirit of the present invention. For example, there are the following (a) to (e).

(A) The aggregation device 30 may create the upper layer incoming call rejection list DB 23 composed of the higher number of registrations in the incoming call rejection list according to purposes such as the national version, the local version, and the latest version. As a result, the contractor can select a desired upper layer incoming call rejection list and appropriately reject incoming incoming calls.

(B) The incoming call rejection service and the upper layer incoming call rejection service of the present embodiment reflect the description contents of the application documents in the terminal DB 21 of the exchange 10 for the subscriber of the service. However, the present invention is not limited to this, and the incoming call rejection service or the upper layer incoming call rejection service may be configured to immediately reflect the user's predetermined operation in the terminal DB 21.

(C) In this embodiment, an incoming call rejection service is provided by a combination of the exchange 10 and the aggregation device 30. However, the present invention is not limited to this, and the incoming call rejection service providing system 1 may be configured so that the exchange 10 has a totaling function. Furthermore, the incoming call rejection service providing system 1 may be configured to divide the aggregation function of the aggregation device 30 and implement it by a plurality of server computers.

(D) The incoming call rejection service of this embodiment is realized by a combination of the exchange 10 and the totaling device 30 in the conventional public telephone network. However, the present invention is not limited to this, and a telecommunications carrier may implement an incoming call rejection service using a call control server in an IP (Internet Protocol) telephone network as a control device and an aggregation device. Further, the communication carrier may realize an incoming call rejection service in a call control device in a mobile communication network.

(E) In the present embodiment, the exchange 10 has a single configuration. However, the present invention is not limited to this, and the exchanges may be configured to be distributed over a plurality of units (for example, regional distribution). In this case, the incoming call rejection judgment control process as shown in FIG. 7 is performed by the exchange on the called terminal side.
