The present invention relates to a multi-ring service, and more particularly, when a service subscriber (recipient) attempts to connect a call to any one of the registered numbers, the subscriber simultaneously sends a ring to all wired and wireless telephones registered by the subscriber, and any one of these terminals. The present invention relates to a multi-ring service providing system and a method of providing the same so that the ring is stopped by other terminals upon receiving this call.

As a call control service provided for call connection to conventional telephone subscribers, there is a form of registering a terminal based on a call transfer type and a virtual number.

Call transfer type service is a service that allows a subscriber to receive a call to a specific number from anywhere by calling the subscriber's telephone number and transferring the call to another registered telephone number.

The service using the virtual number is a personal number service that connects the actual called number registered in the virtual number when the caller calls the virtual number.

However, in the conventional methods, the service is available only when a call is made to a specific number or a specified virtual number for which a transfer is set, and the telephone to be switched is also specified because the telephone number to be switched is also specified by one phone number designated by the subscriber. If the subscriber wants to change the number, there is an inconvenience that the subscriber must repeat the transfer procedure every time.

Accordingly, an object of the present invention for solving the above problems is to improve the call control method so that the subscriber can receive the incoming call regardless of the location of the subscriber.

Multi-ring service providing system of the present invention for achieving the above object is a service management system for storing and managing the information and subscriber information for the wired and wireless terminals of the service subscriber; And a service control system that attempts to connect a call by generating calls for all wired and wireless terminals registered in the service management system with respect to the subscriber when the call connection request is received for the service subscriber.

The present invention provides a multi-ring service providing method comprising: a first step of retrieving all phone numbers registered by a service subscriber upon receiving a call connection request to a service subscriber; And a second step of generating calls for all the retrieved phone numbers and attempting to connect the call to all the phone numbers.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.

1 is a system configuration diagram showing the configuration of a multi-ring service providing system according to the present invention.

The multi-ring service providing system of FIG. 1 includes a service management system (SMS) 10, a service control point 20, and a service switch point 30. It is provided.

The service management system 10 stores and manages information and subscriber information on wired / wireless terminals of subscribers subscribed to the multi-ring service according to the present invention. At this time, the subscriber can register a plurality of wired and wireless telephone numbers desired by the subscriber terminal, and the registered plurality of subscriber terminal numbers are matched and stored for each subscriber.

The service control system 20 generally controls call connection for providing a multi-ring service. When the service control system 20 receives the call connection request message from the service execution exchange 30, the called number of the message is transmitted to the service management system 10 so that the called number is the multi-ring service subscriber according to the present invention. Make sure it is your phone number. And, if the called number is the phone number of the multi-ring service subscriber, the service control system 20 receives all the other phone numbers of the subscriber registered with the called number from the service management system 10 and the corresponding telephone number. Simultaneously generate calls to the numbers and send them to the service execution exchange 30. In addition, the service control system 20 monitors the connection state of each generated call and releases all remaining unconnected calls when any one of the generated calls is connected.

The service performing exchange 30 transmits a call connection request message generated at the originating terminal to the service control system 20, and transmits a plurality of call connection messages generated by the service control system 20 according to the called number. Routing to be transmitted to the subscriber terminal through. That is, the service performing exchange 30 routes a call connection message for a call connection with an Internet telephone (subscriber terminal A) to a VoIP gateway (not shown) of a packet network (internet), and calls with a general landline telephone (subscriber terminal B). The call connection message for connection is routed to a local exchange (not shown) of a public telephone network (PSTN), and the call connection message for a call connection with a mobile communication terminal (subscriber terminal C) is a gateway that connects a wired network with a mobile communication network. Routing to exchanges (not shown).

2 is a flowchart illustrating a multi-ring service providing method according to the present invention.

When a caller makes a call to a mobile communication terminal (subscriber terminal C) of a multi-ring service subscriber using his / her landline telephone, a call connection request message generated at the caller terminal passes through a local exchange (not shown) of a public telephone network (PSTN). It is transmitted to the service performing exchange 30 and the service performing exchange 30 transmits it to the service control system 20 (①).

When the call connection request message is received from the service execution exchange 30, the service control system 20 inquires the multi-ring service profile registered in the service management system 10 (2). That is, the service control system 20 transmits the called number of the received call connection request message to the service management system 10 to determine whether the called number is a phone number subscribed to the multi-ring service, and a phone number subscribed to the service. In case of receiving the received call number, information about the other registered phone number of the corresponding subscriber is provided. That is, the service control system 20 knows all the phone number information registered by the caller to the caller to receive the multi-ring service.

Next, the service control system 20 generates all the calls for all the phone numbers of the subscriber registered in the multi-ring service (③).

The call connection message generated as described above is transmitted to the service execution exchange 30, and the service execution exchange 30 routes the call connection messages to the corresponding networks according to the called party number for each subscriber station A, B, and C. Attempt call connection (④). That is, the service performing exchange 30 transmits a call connection message for subscriber terminal A, which is an Internet telephone, to a VoIP gateway (not shown) that converts VoIP data, and the call connection message for subscriber terminal B, which is a regular landline telephone, is subscriber. Terminal B transmits to the connected local exchange (not shown). The call connection message for the subscriber station C, which is a mobile communication terminal, is transmitted to a gateway exchange (not shown) connecting the wired network and the wireless network.

Accordingly, all of the subscriber stations A, B, and C of the subscriber registered in the multi-ring service ring a ring to notify the call at the same time.

When the subscriber receives a call using any one of subscriber stations A, B, and C due to a ringing tone (⑤), a confirmation message for the incoming response is transmitted to the service control system 20 through the service execution switch 30. (⑥). That is, in FIG. 2, a message informing that the call connection is made through the subscriber station B is transmitted to the service control system 20.

In FIG. 2, a caller calls a subscriber's mobile communication terminal (subscriber terminal C), but the subscriber receives a call by hooking off a landline telephone in his or her office. That is, when the caller calls the subscriber's mobile communication terminal, the caller was able to make a telephone call with the subscriber only when the subscriber possesses the mobile communication terminal. For example, if the subscriber came to the office with the mobile terminal at home, the call was made only after confirming that the caller did not answer the mobile terminal and calling the subscriber's office again. Of course, this is also possible only if the caller knows the subscriber's office number.

However, in the case of the present invention, since all the subscriber's terminals ring at the same time, even if the subscriber does not have a mobile communication terminal, the subscriber can immediately talk to the caller using a landline telephone in the office.

The service control system 20 that has received the incoming response by the subscriber station B releases all the calls to the subscriber stations A and C other than the subscriber station B to which the call is connected (⑦).

In the above-described embodiment, a case in which the user makes a call using one of the actual phone numbers of the subscriber station has been described, but a service using a virtual number is also possible. After assigning a virtual number to each subscriber and matching the subscriber's actual telephone numbers, the caller may make a call to all the actual telephone numbers matched with the virtual number when the caller dials the virtual number.

As described above, in the multi-ring service of the present invention, when a specific number (or virtual number) of a subscriber terminal is dialed, all the subscriber's telephones ring at the same time, thereby allowing the subscriber to receive the incoming call without missing a call. Increase the completion rate of the call.
