Description

Gateway device providing both landline and internet phone service and its method {APPARATUS FOR PROVIDING CONCURRENTLY POTS WITH INTERNET TELEPHONY SERVICE AND METHOD THEREOF}

The present invention relates to a gateway device and a method for providing both a general telephone service and an internet telephone service using a general telephone, and more particularly, a customer subscribed to both a general telephone service and an internet telephone service. By using the device and method, it is possible to use both the general telephone service and the internet telephone service without having a separate internet telephone, and to preset the call to the general telephone or the internet telephone according to the telephone number of the customer to call It provides an optimal call service by having a Rule Based Policy Routing (RBPR) table, and dials emergency numbers such as 119 and 112 through the telephone in the same way as a regular telephone using the telephone regardless of power outage. If you need your location information without any inconvenience 119, 112 A gateway device that can provide an emergency call service and to a method.

Currently, a number (070-NYYY-YYYY, N = 2 ~ 9, Y = 0 ~ 9) for Voice over Internet Protocol (VoIP) service is granted, and the number portability between local and internet phones is available at the end of 2008. With the introduction of policies, the number of customers using the Internet telephony service is increasing rapidly. After using the Internet phone service, the customer must join the high-speed Internet service and receive an Internet phone service by separately providing one of the Internet phone or the Internet phone modem.

There are various kinds of Internet telephones such as terminals supporting not only voice but also video. On the other hand, a device called an Internet telephone modem is a device that allows users to use an Internet telephone service by connecting a regular telephone used at home to an internet telephone modem. Using such an internet telephone modem has the advantage that it is possible to use an internet telephone service without having a separate internet telephone. Internet phone modems that do this are sometimes called adapters, adapter devices, gateways, home gateways, or set top boxes (STBs).

The biggest advantage of Internet telephony service is that call charge is low. However, in order for a customer having both a regular phone and an internet phone at the same time to pay the most economically, a call has to be used by selecting a general phone or an internet phone according to the phone number of the counterpart. For example, a customer who has subscribed to both a regular telephone service and an Internet telephone service can call another local telephone subscriber in the city by using a local telephone or an internet telephone, and then call the other party. If the number is a long distance phone number or a mobile phone number, there is a disadvantage that you need to make a call by Internet phone. That is, there is a disadvantage in that a customer must select and use a general phone or an internet phone according to the phone number of the counterpart.

In addition to the above drawbacks, the biggest disadvantage of the Internet phone and the Internet phone modem for providing the Internet phone service is that the Internet phone or the Internet phone modem can not be provided without power to the Internet phone service. In addition, during a power outage, there was a disadvantage that emergency telephone services such as emergency rescue or fire or crime reporting, which need to call 119, were not available. Even if the power is supplied, an internet phone cannot deliver services such as 119 and 112, which require the customer's location information, like a public switched telephone network (PSTN), which has another disadvantage of causing personal or property damage. On the other hand, PSTN, which provides a general telephone service, is provided even during a power outage, and has an advantage of accurately providing a customer's location even in an emergency situation.

Therefore, in case of emergency, customers using the Internet phone service had a disadvantage of having a regular phone. In addition, there is a disadvantage that the customer usually uses the Internet phone service, and in case of power failure or emergency call such as 119 where the customer's location information is required, the general phone service is required. As a result, customers should always keep in mind or care about whether there is a power outage or whether the power cord of the internet phone modem is connected to a power source.

In addition, when the customer terminates the general telephone service and uses only the Internet telephone service, there is a disadvantage in that an emergency telephone service such as 119, which can secure life, cannot be received.

On the other hand, the conventional technology to compensate for the problem of power failure, which is a disadvantage of the Internet phone, the Internet phone modem when the power is supplied, the telephone can be connected to the Internet phone, when the power is not supplied to the PSTN telephone method There is an internet phone modem that makes this possible. Calls made through the conventional internet phone modem are basically dialed out to the Internet phone first, and after dialing a special button (*, #) on the telephone number pad and dialing the phone number of the party to be called, the PSTN phone method is used. To make a call.

However, this conventional method has a disadvantage in that a customer must decide whether to make a call over a general telephone network or an internet phone every time he tries to make a call. In addition, in an emergency situation, the emergency telephone number must be dialed after at least one dial of the special button (*, #) to use the emergency telephone service provided by the PSTN.

That is, the prior art as described above should be determined every time a customer attempts to make a call, whether to make a call to a general telephone network or an internet phone, and in an emergency, after emergency dialing of a special button at least once, There is a problem that you can use the emergency call service provided by the PSTN only by dialing a number, which is an object of the present invention.

Therefore, according to the present invention, after creating and storing a routing table for each prefix of the telephone number, the rule analyzes the telephone number dialed by the customer to look up the routing table to provide a telephone service with the routing path set by the client. It is an object of the present invention to provide a gateway device having a Rule Based Policy Routing (RBPR) function and a method thereof.

FIG. 10 is an exemplary view showing a connection path when a customer receives a telephone call from a general telephone customer according to the present invention. The customer of the general telephone 102 provides both a general telephone and an internet telephone service according to the present invention. The connection path in the case of trying to call the customer of the general telephone 101 connected to the gateway device is shown.

As shown in FIG. 10, a signal transmitted from the PSTN 103 to a customer using the gateway device 200 according to the present invention is formed with a call path through an internal circuit of the gateway device 200.

For example, FIG. 10 shows a connection path in which a general telephone service is provided between a local telephone-local telephone and a local telephone-long distance telephone.

FIG. 11 is an exemplary view showing a connection path when a customer receives a telephone call from an Internet telephone customer according to the present invention, and is a customer of a general telephone 101 connected to a gateway device that provides both a regular telephone and an Internet telephone service. Shows the connection path when the customer of the Internet telephone 111 attempts to make a call.

Here, the caller ID display device of the general telephone 101 displays an 070-NYYY-YYYY number which is an Internet telephone number. At this time, when the number is transferred from the local telephone to the Internet telephone, the general telephone number is displayed instead of the Internet telephone number.

For example, Fig. 11 shows a connection path in which an Internet phone service is provided between an Internet phone and an Internet phone.

12 is an exemplary structural diagram of a routing table set by a customer to perform rule based policy routing (RBPR) according to the present invention, which provides both a general telephone and an internet telephone service according to the present invention. In the gateway device, an embodiment of a rule-based policy routing table for distributing a call according to rule base policy is shown.

If the customer using the gateway device 200 according to the present invention wants to use the telephone service in the least expensive way, the caller is a local call or a long distance call with the same call zone, but the distance between the call passes is within 30 km. It is the cheapest to call by local phone. And customers can use the Internet phone service if the call partner is more than 30Km long-distance phone, mobile phone, Internet phone to talk to the other party via internet phone is the cheapest.

However, many customers live in their respective calling zones, and even though they belong to the long-distance telephone zone, the right to pay local telephone fees within 30 km is also different depending on the right of residence. Therefore, the contents of the rule-based policy routing table for each currency segment should be different for each customer. In order to solve this problem, the customer installs the gateway device 200 according to the present invention while rule-based policy routing in the form of ## area code + station code ## (or various combinations such as ** area code + station code **) When the table setting command is entered, the cheapest rule-based policy routing table is automatically selected and set according to the area code and station code.

To this end, for example, the contents of the rule-based policy routing table for each currency zone are stored in advance in the memory 216, and various combinations such as ## area code + station code ## (or ** area code + station code **) are possible. ) Is input, the rule-based policy routing table according to the area code and the station number is automatically selected and set from the rule-based policy routing table for each currency zone stored in the memory 216. Alternatively, the contents of the rule-based policy routing table for each currency zone are stored in advance on an external server, and when ## area code + station code ## (or multiple combinations such as ** area code + station code **) is input, The area code and the station number may be transmitted to the external server to automatically download and set a corresponding rule-based policy routing table from among the rule-based policy routing tables for each call right stored in the external server.

In FIG. 12, PFX represents a prefix, PTY represents a prefix type, MIN represents a minimum digit, and MAX represents a maximum digit. RLST is a root list, meaning that 1 is routed to the PSTN and 2 is routed to the Internet.

For example, if the incoming call number dialed by the customer starts at 1 and is at least 3 to 8 digits long, the call is routed to the PSTN by default. For example, 119, 1588-YYYY and the like are routed to the PSTN.

When the customer dials a telephone number starting with 070, the PFX is 070, so the RLST is set to 2, so that the call is routed to the Internet to provide an Internet telephone service.

Next, according to the method provided by the present invention, an embodiment for setting up a rule-based policy routing table by a customer residing in Daejeon where the area code starts with 042 will be described. If the gateway device 200 according to the present invention is provided and the ## 042 (area code) 486 (country code) ## is entered, the rule-based policy routing table as shown in FIG. 12 is automatically set, thereby providing a gateway according to the present invention. It is stored in the memory 216 of the device 200. Therefore, all phone calls with 042, 041-73Y, 041-75Y, 041-85Y, 041-86Y, 043-2YY, 043-73Y, 043-54Y, and 043-9YY are included in the local area. In accordance with the rule-based policy routing table of FIG. A telephone call having a station number other than that is transmitted to an internet telephone according to the rule-based policy routing table of FIG. 12. (Y = 0 to 9)
