Apparatus and method for providing calling service using forwarding function}

The present invention relates to an apparatus and a method for providing a telephone service, and in particular, a telephone number using a call forwarding function to provide a discounted telephone service called a calling card or a specially designated telecommunications business that provides discount rates for long distance calls, mobile phones, and international calls. And an apparatus and method for providing a telephone service using a call forwarding function for automatically searching for a called party's telephone number according to a calling party's telephone number and executing a connection by calling the retrieved called party's telephone number.

In the general telephone communication system as shown in FIG. 1, in order to use a discount card service provided by a calling card service and a separate telecommunications service provider, when a caller is used in a public phone, a normal access number + PIN number + incoming call number 3 steps If you make a call from a regular phone or mobile phone, you need to pre-register a caller number called CLID (Calling Number Identification) with the service device so that when you make a call, you can skip the PIN number by checking the CLID. Even in this case, enter the access number + incoming call number in step 2 to use the service. Accordingly, since the existing calling card service inputs at least two levels of numbers, it saves money compared to a general telephone service, but there is a problem in that it is inconvenient to use. In addition, for the first time customers who use these services, if you connect the access number in a foreign country, you can hear the voice recorded in English or a foreign language, or you must select a specific number to hear the Korean voice. There is a problem that is embarrassing or inconvenient to use because it provides only foreign language voice services such as English or Japanese.

And in order to eliminate the inconvenience of inputting two or more steps, if you enter the incoming phone number only once, the phone automatically analyzes the area code to classify long distance, mobile, and international calls, and access number and PIN number corresponding to each service. If you are a telecommunications service provider that provides a special telephone with a built-in ACR function to your subscribers, you may be able to partially solve the above problem, but do not use a cordless wireless telephone. The same uncomfortable problem is that you must enter at least two levels of phone numbers, including public telephones or cell phones, and while traveling abroad, including access numbers. In addition, in the case of supplying ACR telephones, a separate budget, supply and installation procedures are required, and there is an inconvenience in that it is necessary to explain the usage to the customer.

In addition, there is a case of using a special area code called 007xx to improve the inconvenience, but to add such a function to the corresponding exchange in the country or to provide a 007xx number, a restriction must be qualified to use a separate and separate for use of the 007xx number There is a cost burden, and there is a problem that subscribers memorize 007xx special number separately.

As described above, in order to use the international telephone discount service, there is a problem that a complicated environment and an uncomfortable method must be used rather than the usual phone use environment and method.

The technical problem to be solved by the present invention is to prepare a special telephone with an ACR function to solve the above-mentioned problems, or input a number of at least two levels including the access number, or hear the voice message after connecting the access number. In order to completely solve the problem of memorizing or using a special prefix such as 007xx, the caller can also use the same number of callers without changing the environment of using the phone at all times. The present invention provides an apparatus and method for providing a telephone service using a call forwarding function that automatically makes a call to a registered called party number corresponding to a number and an access number.

It is done.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2, the communication system to which the telephone service apparatus using the call forwarding function according to the present invention is applied includes telephones 1, 2, 3 (201, 209, 212), switch 1, 2 (202, 208), and various communication line networks (204, 205). , 206, 207, Internet phone terminal 210, DID call forwarding gateway 203, database 211.

In the database 211, the called party's telephone number is matched with the calling party's telephone number and the access number and stored. Alternatively, the database 211 may be designed such that the caller's telephone number is omitted and the called party's telephone number to be automatically forwarded to the access number is matched and stored.

General User Telephones 1, 2, and 3 (201, 209, 212) are common telephones that we use in our lives. If the customer makes a call to the registered telephone number, a signal is sent to the DID call forwarding gateway 203 through the exchange. At this time, the DID call forwarding gateway 203 registers inside the device after checking the access number. The destination database number matched with the access number registered in the database 211 is searched for and is automatically controlled to connect to the call of the destination through the required communication network.

The inter-station line connection unit 31 allows the communication line connection with the switch network to be made, and the general T1, E1, PRI ISDN general telephone network is connected. The signal entered into the inter-line connection part 31 controls the communication network connection part 32 to be connected to the general international telephone network or the general telephone network based on the communication network information registered in the database 34 in the system control unit 35. The communication network connection unit 32 performs a role of selecting one communication network among various communication networks and connecting them to a call path under the control of the system control unit 35. In the case of using a VoIP phone, the voice codec conversion 33 is performed, and then the packet processing unit 36 is processed, and then the communication network connection unit 32 is connected to the external network.

4 is a flowchart of a call service method using a call forwarding function according to the present invention. When a general user presses a phone number to make a call request, a caller's CLID number is indicated when a registered DID (Direct Inward Dial) is called. This is a description of confirming whether the customer is a registered customer, searching for a destination number corresponding to the DID access number stored in the database in a 1: 1 manner, and automatically dialing the destination number to connect the call path.

Next, a telephone service method using the call forwarding function according to the present invention will be described in detail with reference to the flowchart of FIG. 4.

First, it is determined at the switch 1 202 whether a signal of a telephone number requesting a call is received from the telephone subscriber (step 401). If the telephone number signal of the call request is received at the switch 1 (202), the telephone number of the received signal is a DID call forwarding telephone number (aka, connection number) stored in a database inside the switch 1 (202). (Step 402).

If the telephone number of the signal to be called corresponds to the registered DID call forwarding phone number, the DID call forwarding gateway 203 sends a signal of the DID call forwarding phone number. Then, the information about the destination telephone number and the registered communication network corresponding to the DID call forwarding phone number is read from the database 34 of the DID call forwarding gateway 203, and when the user matches the registered caller CLID, The registered communication network is selected and the destination telephone number is sent (steps 403 and 404).

Then, a telephone signal is received from the destination telephone through the communication network registered by the user who subscribes to the DID call forwarding telephone number, and the ringing tone is received from the telephone 2 209 or the Internet phone terminal 210 having the destination telephone number. (Step 406).

In step 407, it is determined whether the hook is turned off at the destination telephone or the receiver is picked up.

If it is determined in step 407 that the incoming call is answered and the telephone hook is turned off, that is, the receiver is picked up, the caller is connected to the call path so as to execute a telephone call (step 408).

However, if the telephone number of the telephone request signal received as a result of the determination in step 402 is a telephone number that does not correspond to the registered DID call forwarding telephone number, the call itself is rejected (step 405). However, if the telecommunication service provider directly or indirectly participates in the service, it may be able to send to the switch 2 208 of the destination area through the general international communication network 204.

If it is determined in step 403 that the registered caller CLID does not match, after confirming the PIN number, the process moves to step 404 to execute subsequent steps.

In the above configuration, steps 403 and 409 may be omitted, and it may be designed to directly enter step 406 in step 402.

In the above process, when the exchange 1 202 and the DID call forwarding gateway 203 make a call using the DID incoming call phone number, the caller can make a call to a called party in a foreign country using the domestic phone number. As a result, it is possible to make a very convenient call and to obtain a double effect to reduce the telephone bill.

For example, 555-2001 (registered as US branch office: 213-251-5775), 551-2002 (mobile phone of US branch office), 551-2003 (Japanese branch office), 551-2004 (mobile branch office in Japan), 551-2005 (Son studying abroad in the US), 551-2006 (son's mobile phone studying abroad), 551-2007 (Busan branch office), 551-2008 (Gwangju branch office) No matter whether you are at home, on your cell phone or in the office, you can dial 555-2001 and the device developed by the present invention will automatically dial 213-251-5775 in the United States.

The present invention has been described by limiting the phone number of the destination to be transferred to the DID for convenience of explanation to other countries, the phone number of the destination can be applied to other provinces or mobile phones in the same country, and also of the present invention It is natural to be included.

As described above, according to the present invention, an international telephone service system apparatus having a built-in DID telephone number and an incoming call function is developed, and a plurality of DID numbers registered in the apparatus are called out-of-country and overseas incoming numbers with many telephone calls. And by providing a call forwarding to 1 and 1, the customer can enter the domestic and overseas phone number only once in all the environment and the phone you normally use, you can make a call directly with the recipient of the intercity or overseas registered Effect occurs. It is as convenient as if the remote party is living in the same area as the caller.
