Description

The present invention relates to a telephone number of a caller (hereinafter referred to as a caller number) of a call transferred to a mobile terminal (hereinafter referred to as a mobile terminal) such as a mobile phone or a smartphone via a private branch exchange (hereinafter referred to as a switch). The present invention relates to a system and a method capable of notifying a telephone number of a caller instead of a station line number accommodated in an exchange that has executed a transfer.

Currently, in the business scene, when a sales person or service person uses a mobile terminal to make a phone call to a customer's landline, it is common to dial the other party's phone number directly from the area code. It is.

On the other hand, there is a method in which a service called an additional dial-in provided by a carrier is combined and transmitted from a portable terminal to the telephone number of the other party using a public network via an exchange of his company. Specifically, dial “company phone number + special number + destination phone number”.

An additional dial-in number assigned to the mobile terminal of the caller's salesman is displayed on the customer's telephone that has received a call made in this manner, and is recorded in the incoming call history. If the customer makes a call back to that number, the mobile phone of the salesman can be called via the exchange of the company of the calling salesman.

When you make a call using this method, if you combine the flat-rate service between the mobile terminal provided by the carrier and the fixed line, you only need to charge the call from your switch to the other party's phone. Compared to dialing and making calls, the price is cheaper, so business use is also progressing.

However, in the method using the additional dial-in described above, when the customer calls the additional dial-in number of the salesperson, the call is transferred to the mobile terminal on the receiving side from the viewpoint of preventing the caller ID from being forged. Since the office line number accommodated in the exchange is to be displayed, the telephone number of the caller cannot be displayed as the incoming call number.

In such a situation, the owner of the mobile terminal that has received the call cannot determine who the caller is.

Accordingly, an object of the present invention is to display a caller number of a call sent to an additional dial-in number on a transfer destination mobile terminal and to notify an incoming call history when a call cannot be answered.

In order to solve the above problems, a caller ID notification system according to the present invention receives a caller ID and a destination additional dial-in number included in an incoming signal from an exchange, and receives the received caller number and destination additional dial-in. Means is provided for storing the number as history information together with the reception date and time and notifying the caller number in response to an inquiry from the portable terminal.

In addition, in a portable terminal that receives a call forwarded from the exchange, a means for inquiring the caller ID notification device of the caller ID notification device when the call is received and the caller ID notified from the caller ID notification device are displayed. And a means for performing the processing.

Furthermore, even if the mobile terminal that receives a call forwarded from the exchange cannot respond to the incoming call or cannot receive the incoming signal due to being outside the communicable area, the caller ID Means is provided for acquiring and displaying incoming call history information from the notification device.

By the above means, the caller ID of the call sent to the additional dial-in number is displayed on the transfer destination mobile terminal, and if it cannot be answered, even if it is outside the communicable area It is possible to obtain and check the incoming call history later.

(System operation)
(Operation example 1: Normal operation)
First, with reference to FIG. 5, the operation of the caller ID notification system when a call is sent from the telephone terminal 4 to the portable terminal 3 via the exchange 1 will be described.

When a call is made from the telephone terminal 4 to the additional dial-in number assigned to the portable terminal 3, the call is first received at the exchange 1 accommodated in the portable terminal 3 (step 1).

The exchange 1 acquires the caller number and the additional dial-in number from the incoming signal (step 2), and transmits them to the caller number notification device 2 (step 3). Further, a call connection request is made to the mobile terminal 3 associated with the additional dial-in number (step 4).

The caller ID notification device 2 acquires the caller ID and the additional dial-in number from the exchange 1 (step 5), stores them in the history information storage unit 24 in association with the reception date and time (step 6), and push notification service An incoming call notification request is made to 61 (step 7).

In response to the request from the caller ID notification device 2, the push notification service 61 transmits incoming notification information to the portable terminal 3 (step 8).

The portable terminal 3 that has received the call connection request from the exchange 1 and the incoming call notification from the push notification service 61 inquires of the caller number notification device 2 about the caller number (step 9).

The caller ID notification device 2 receives an inquiry from the mobile terminal 3, searches for the corresponding caller ID from the history information storage unit 24 (step 10), and notifies the mobile terminal 3 (step 11).

The portable terminal 3 displays the caller number of the call received from the caller number notification device 2 on the screen (step 12). A call is started by responding to the call connection request from the exchange 1 (step 13).

At this time, the name of the caller can be displayed together with the caller number by linking with the phone book data stored in the portable terminal 3 based on the received caller number.

Further, even when the mobile terminal 3 does not respond to the incoming call, it is possible to acquire the incoming call history information from the caller ID notification device 2 and display it.

(Operation Example 2: Operation when Mobile Terminal 3 is Out of Service Area and Call and Internet Connection are Impossible) Next, referring to FIG. 6, the transfer destination mobile terminal 3 cannot make a call and connect to the Internet. The operation of the caller ID notification system will be described.

The operation from step 1 to step 3 shown in FIG. 6 is the same as the operation from step 1 to step 3 shown in FIG.

In step 4, the exchange 1 makes a call connection request to the transfer destination mobile terminal 3. In this example, it is assumed that the call connection cannot be made because the mobile terminal 3 is outside the communicable area.

Here, the exchange 1 stops the call connection request and sends a busy tone to the telephone terminal 4 (step 5).

The caller ID notification device 2 acquires the caller ID and the additional dial-in number from the exchange 1 (step 6), stores them in the history information storage unit 24 in association with the reception date and time (step 7), and push notification service An incoming call notification request is made to 61 (step 8).

The push notification service 61 receives a request from the caller ID notification device 2 and notifies the mobile terminal 3 of an incoming call. In this example, the mobile terminal 3 is out of a communicable area. Incoming call notification is not possible (step 9).

Therefore, in this case, since the call connection request does not reach the mobile terminal 3 and the incoming call notification does not arrive, it cannot be recognized that there is an incoming call at this time.

However, when the push notification service 61 recognizes that the mobile terminal 3 has moved into the communicable area and notifies the mobile terminal 3 of the incoming call again (step 10), the mobile terminal 3 informs the caller ID notification device 2 On the other hand, it is possible to request history information (step 11) and obtain an incoming call history (steps 13 and 14).

(Operation Example 3: Operation when the mobile terminal 3 is out of service area and cannot make a call but can connect to the Internet via a wireless LAN)
Depending on the type of the mobile terminal 3, there is a terminal that can be connected to the Internet 6 using a wireless LAN or the like. The operation of the caller ID notification system will be described with reference to FIG. 7 when such a portable terminal 3 cannot make / receive calls, such as an underground shopping mall, but can be connected to the Internet 6. .

The operation from step 1 to step 3 shown in FIG. 7 is the same as the operation from step 1 to step 3 shown in FIG.

In step 4, the exchange 1 makes a call connection request to the transfer destination mobile terminal 3. In this example, it is assumed that the call connection cannot be made because the mobile terminal 3 is outside the communicable area.

Here, the exchange 1 stops the call connection request and sends a busy tone to the calling terminal (step 5).

The caller ID notification device 2 acquires the caller ID and the additional dial-in number from the exchange 1 (step 6), stores them in the history information storage unit 24 in association with the reception date and time (step 7), and push notification service An incoming call notification request is made to 61 (step 8).

The push notification service 61 receives a request from the caller ID notification device 2 and notifies the portable terminal 3 of an incoming call (step 9).

The portable terminal 3 that has received the incoming notification from the push notification service 61 inquires of the caller number notification device 2 about the caller number (step 10).

The caller ID notification device 2 receives an inquiry from the mobile terminal 3, searches for the corresponding caller ID from the history information storage unit 24 (step 11), and notifies the mobile terminal 3 (step 12).

The portable terminal 3 displays the caller number of the call received from the caller number notification device 2 on the screen (step 13).

In this example, since the mobile terminal 3 is outside the callable area, the call connection request does not arrive, but since the connection to the Internet 6 is possible, the incoming call notification can be received.
