Abstract

A call routing method for identifying an intra-lata call and an inter-lata call and a user interface method of an auto dialer are provided to transmit only an inter-lata call to a connection device for a long distance call by accurately grasping whether an originating call is an inter-lata call, thereby enabling a user to use a telephone service without time and costs. When a lata code of a searched record is different from a lata code of an caller number, the lata code of the searched record is determined as an inter lata call. And a long distance call connection access code and an inputted receiver phone number are combined. And the combined telephone number is transmitted. When the same record as LSC of the receiver telephone number is not searched, the long distance call connection access code and the input receiver phone number are combined. And the combined phone number is transmitted.

According to the present invention, a call routing method for distinguishing between Intra-Lata Call and Inter-Lata Call, and whether or not to use an autodialer (Auto-Dialer) are used. The present invention relates to a method of user interface that is not recognized by a user. Specifically, an auto dialer is used to access a long-distance telephone operator's switching equipment (RADIUS). And a user interface method of an auto-dialer.

Until now, in order to distinguish between Intra Lata and Inter Lata, it has been inconvenient and inaccurate because the user has to rely on the memory every time or find and dial after referencing related data. In addition, even when using an auto dialer, it is common to send all outgoing signals beginning with a specific number to a predetermined long distance call access device. Intra Lata and Inter Lata There was a problem that the function of distinguishing the call numbers could not be supported (ex. 1-xxx-yyy-zzzz, all the calling numbers are sent to the prepaid card operator's exchange equipment. X is 200 to 999 except for the toll free number. All numbers between).

The operating process of this conventional prepaid card model is shown in FIGS. 1A and 1B. FIG. 1A is a flowchart of a case where a user directly distinguishes an area (Intra Lata) / Long distance (Inter Lata) call, and FIG. 1B is a case of using a conventional auto-dialer. Is a flow chart. Referring to FIGS. 1A and 1B, a conventional telephone connection process will be described below.

First, referring to FIG. 1A, a processor in a case where a user directly distinguishes a local or long distance call will be described.

The user subscribes to a local telephone service and purchases a prepaid card for long distance and international calls (ST100, ST105).

The user directly distinguishes local, long distance, and international calls, and if the user originates a local call, the local call is relayed by a local exchange at the time of subscription (ST110, ST115). In addition, when the user originates a long distance call or an international call, the long distance and international calls are relayed through the long distance operator equipment after accessing the long distance call operator equipment (gateware or switch) (ST120, ST125).

Next, the process in the case of using an Auto-Dialer is shown in Fig. 1B.

A user who subscribes to a local telephone service purchases a prepaid card for long distance and international calls and then dials out local, long distance and international calls (ST150 to ST160).

Auto-Dialer unconditionally transmits access code for long-distance call connection, so it connects to long-distance call operator equipment (gateway or switch) and relays local, long-distance and international calls through long-distance operator equipment. (ST165 to ST175).

Therefore, as described above, when the user directly transmits a local or long distance call, as shown in FIG. 1A, the user may not only be inconvenient because of the inconvenience, but also have a problem of incorrect dialing. In addition, even when using an auto dialer as shown in FIG. 1B, a conventional auto dialer does not support a function of distinguishing between an Intra Lata and an Inter Lata. There was a problem that the user still suffers from inconvenience.

On the other hand, the conventional auto-dialer requires more time to connect to the receiver (the time it takes for the ring tone to be heard by the caller) than when the auto-dialer is not used. You will need approximately a few more seconds. Also, if you use a regular phone without an auto-dialer, only the white tone, dial tone, and ring back tone that are heard when dialing the recipient's phone number are generated. If you use the dialer (Auto-Dialer), a sound other than the above three sounds will be generated. Therefore, when using an auto dialer, there is a problem that a user knows that an auto dialer is used.

Embodiments of using a conventional auto-dialer are shown in FIGS. 9 and 10. Conventional auto-dialers, as described above, require more time to connect to the recipient when in use than when the auto-dialer is not used, and the caller also has a white tone. ), Dial tone, ring back tone, and “dial tone sound”.

9 is a diagram illustrating a first use embodiment of a conventional auto-dialer. Referring to FIG. 9, a first embodiment of a conventional auto-dialer will be described.

In the United States, the cost of long-distance or international calls varies by phone provider, allowing users to access a network of cheaper long-distance or international phone providers using a calling card.

The caller selects the calling card to be used (ST400). When the caller uses the calling card, the access number (usually 11 digits, like an ordinary phone number, is called AN (Access Number)) and the caller identification number (usually 6 ~) to access the telephone card provider's network. 12 digits (hereinafter referred to as Personal Identification Number) must be entered first.

When using a calling card like this, the auto-dialer automatically dials the number to be dialed manually (AN and PIN), so the caller can dial by using the auto-dialer. .

The user starts the auto-dialer by dialing a pre-entered * or #, and the auto-dialer automatically dials the AN and PIN to access the telephone card operator's network (ST405). , ST410). The auto-dialer connects to the telephone card provider network through the AN and the PIN, and the user enters the recipient's telephone number after confirming the access to the telephone card provider network (ST415, ST420).

The auto-dialer transmits the input recipient's telephone number through the telephone provider's network (ST425).

As such, when the auto-dialer is used, the auto-dialer automatically dials the AN and the PIN, so that the caller does not need to manually enter a complicated AN and PIN.

However, the conventional first embodiment shown in Figure 9 has the following disadvantages.

1) The caller should decide in advance before selecting which operator's network to make long-distance or international call among various long-distance operators' networks. There was a ham.

2) Since it is necessary to dial * or # in order to drive the auto-dialer in the steps ST405 and ST410, there is a problem that it takes more time than when the auto-dialer is not used. It will take about a few more seconds.

3) The sender, in addition to the white tone, dial tone, and ring back tone, is compared with the case of not using the auto-dialer during the process of ST405 and ST410. The user will hear additional sounds of the auto-dialer dialing *, #, AN, and PIN, and the user will recognize that the auto-dialer is being used.

10 is a view illustrating a second use embodiment of the conventional auto-dialer. Referring to FIG. 10, a second embodiment of a conventional auto-dialer will be described.

The caller first dials the number of the fishery destination without determining whether the auto-dialer is driven (ST500).

The auto-dialer does not run until the caller enters all the recipient's phone numbers. After the caller enters all the phone numbers, the auto-dialer compares the recipient's phone number with the embedded database (ST505, ST510). Specifically, the auto-dialer compares the inputted telephone number with a built-in telephone number pattern database, finds a telephone number pattern that matches the inputted telephone number, and then finds the corresponding telephone number pattern ( It operates according to the execution rule for the pattern) (ST515).

FIG. 10 illustrates an example in which the caller accesses the C telephone network according to the third telephone number pattern of the pattern database when the caller inputs '1-999-999-9999'. The Auto-Dialer dials the AN number and PIN number to access the C carrier network, accesses the C carrier network, and then dials the temporarily stored recipient's phone number (the phone number entered by the caller on the ST500). It dials (ST520 to ST530).

In the second use embodiment, the caller has in common with the first use embodiment in that the caller uses an auto-dialer to automatically dial the PIN & AN of the calling card. It differs from the use embodiment.

1) The subject of selecting a telephone operator is different. That is, in the first use embodiment, the caller selects the operator's network in advance and makes a call. In the second use embodiment, the caller uses an auto-dialer through a receiver number and a database embedded in the auto-dialer. Will select the network of the telephone provider.

2) The timing of choosing a network for a telephone operator is different. That is, in the first use embodiment, which telephone operator's network is to be used before the user inputs the recipient's telephone number, in the second use embodiment, the telephone operator's network is determined after inputting the receiver's telephone number. .

This second embodiment uses an auto-dialer to automatically dial the AN and PIN, so that the user does not have to memorize the complex AN and PIN. There was no inconvenience to decide in advance whether to make long distance or international call by selecting operator's network before dialing receiver's phone number.

However, the second use example has the following disadvantages.

1) There was a problem in that it takes about several seconds to several tens of seconds than the case of not using an auto-dialer while performing ST505 to ST515 and ST530 processes. That is, the auto-dialer does not run until the recipient enters all 11 digits of the telephone number in step ST505, and later resets the recipient's phone number temporarily stored by the auto-dialer in step ST530. Because of dialing, it takes additional time. In addition, it takes additional time for the auto-dialer to search the database in steps ST510 and ST515.

2) The caller goes through the ST520 and ST530 steps after entering the recipient's phone number, in addition to the phone number white tone, dial tone, and ring back tone, in addition to the auto-dialer. ) Hears the dialing of AN and PIN, which makes the auto-dialer aware.

The present invention has been presented to solve the above problems, and an object of the present invention is to add a new routing function to a conventional auto-dialer, so that Intra Lata is a local telephone service provider. Inter Lata calls are inter-Lata calls and Inter Lata calls that allow long-range call access equipment to route automatically without additional input from the user. It provides a call routing method that distinguishes calls.

In addition, another object of the present invention is to shorten the connection time to the receiver as much as possible and to cut off all the additional tone to be generated by using the auto-dialer in the middle to give the caller the white tone ( Only the white tone, dial tone, and ring back tone can be heard, indicating that the auto-dialer is running while the user is using the auto-dialer. It is to provide a user interface method that can be hidden.

In order to achieve the above object, a call routing method for distinguishing between an Intra Lata call and an Inter Lata call according to the present invention, the caller dialing Recipient's telephone number is inputted, and the receiver's telephone number is compared by comparing each record in the routing table composed of LSC and Lata Code, which is a combination of Area-Code and Prefixes, among the recipient's telephone numbers. Calls an Intra Lata call if the call belongs to the same Lata as the calling party's phone number, and an Intra Lata call is determined to be an Inter Lata call if the caller's phone number belongs to another Lata with a different caller ID. A call routing method that distinguishes between a call and an inter-lata call, comprising: a first step of receiving a caller's telephone number to which a caller dials; The second step of retrieving the same record by comparing each record in the routing table sequentially, if the Lata code of the retrieved record is the same as the Lata code of the calling party's telephone number, Intra Lata A third step of calling only the input recipient's phone number, and if the Lata code of the searched record is different from the Lata code of the caller's phone number, it is determined as an Inter Lata call, The fourth step of combining the access code for the call access and the entered recipient's telephone number, and the combination of the long distance call access code and the entered recipient's telephone number if the same record as the LSC of the recipient's telephone number is not found. And a fifth step, wherein the third to fifth steps are selectively performed.

Preferably, before the first step, the method further comprises steps 1-1, in which the caller designates an arbitrary code having one or more digits as an access code for a predetermined designated telephone number, and the first and second steps. In the meantime, if the receiver telephone number input in the first stage is the same as the access code, the first and second stages of searching for the same record by comparing each record in the routing table with the LSC of the designated telephone number, If the Lata Code is the same as the Lata Code of the caller's phone number, steps 1-3 for sending only the designated phone number, the Lata Code of the retrieved record and the Lata Code of the caller's phone number Is different, the method further includes the first to fourth steps of combining the access code for the long distance call and the designated telephone number, and allowing the first to third steps and the first to fourth steps to be selectively performed.

More preferably, before the first step, the caller further comprises steps 1-5, wherein the caller registers the service code starting with the predetermined code, and between the first and second steps, the recipient's telephone number is the service code. If it is equal to and further comprising the step 1-6 of sending a service code.

In addition, in order to achieve the above object, in the routing table configuration method according to the present invention, it is determined whether the caller's telephone number dialed by the caller and the caller's telephone number belong to the same Lata to determine whether the receiver's telephone number is Intra RATA. In order to determine Lata and Inter Lata calls, a routing table composed of LSC and Lata Code, which is a combination of Area-Code and Prefixes, is configured for each Lata A method of configuration, comprising: a first step of mapping and registering a * and # code with at least one of a predetermined recipient telephone number registered by a caller and a telephone number not using an access code for long distance call access, and exchange of an international call operator The second step of registering by registering the access code for the equipment and IDP (International Dialing Prefix), the service code input by the caller and the service The third step of mapping and registering the combined code of the code and # code, the fourth step of registering by registering the unique number of the Carrier Identification Code (CIC) entered by the caller and the null, and the burden of the ERC (Easily Recorgnizable Code). The fifth step of selecting and entering numbers, mapping them with null and registering them, and distinguishing and inputting only the combined code of '1' which is ICC (International Calling Code) and LSC record for Lata area of caller's phone number And a sixth step of registering, wherein the first to sixth steps are performed regardless of the order.

In addition, in order to achieve the above object, another embodiment of the routing table configuration method according to the present invention, the receiver telephone number by determining whether the caller's telephone number and the caller's telephone number dialed by the caller belong to the same Lata In order to determine Intra Lata and Inter Lata calls, LSC and Lata Code, which is a combination of Area Code and Prefixes, are included in the recipient's phone number. A method of configuring a routing table for each state, the method comprising: a first step of mapping and registering * and # codes with at least one of a predetermined receiver phone number registered by a caller and a telephone number not using an access code for a long distance call, The second step of mapping and registering the access code for the exchange equipment of the international call provider and the International Dialing Prefix (IDP), and the service code entered by the caller. The third step of registering by mapping the combined code of the code, service code and # code, the fourth step of registering by registering the unique number of the Carrier Identification Code (CIC) entered by the caller and null, and the ERC (Easily Recorgnizable Code) A fifth step of selecting and entering a toll free number among the numbers and mapping it with null and registering the code with a combination of '1', which is an International Calling Code (ICC), and the LSC for the Lata area of the caller's state. And a sixth step of inputting a Lata code for the first step, wherein the first to sixth steps are performed regardless of the order.

In addition, in order to achieve the above object, another call routing method for distinguishing between the Intra Lata call and the Inter Lata call according to the present invention In an embodiment, a caller receives a caller's telephone number dialed, and a combination of a '1', which is an International Calling Code (ICC), and an LSC, which is a combination of Area-Code and Prefixes, is a combination of a caller's telephone number and a Lata code. Code) and compares each record in the routing table created by state with the recipient's phone number. If the recipient's phone number belongs to the same Lata as the calling party's phone number, it is determined as an Intra Lata call and the recipient's phone number is the calling phone. If the number belongs to a different Lata, Call Routing distinguishes between an Intra Lata call and an Inter Lata call that is determined to be an Inter Lata call. As a method, The first step of inputting the recipient's phone number dialed by the caller, the second step of searching for a record combining '1' and LSC matching the recipient's phone number, and if no record is found, it is determined as Inter Lata. A third step of combining the access code for the long distance call and the inputted recipient's phone number; and a fourth step of determining whether or not the Lata code of the searched record and the Lata code of the caller's phone number are the same. Step 5, if the Lata code of the searched record and the Lata code of the caller's phone number are the same, the fifth step of transmitting only the input recipient's phone number determined as an Intra Lata call, and of the searched record If the Lata Code is different between the Lata Code and the calling party's telephone number, it is determined as an Inter Lata call. With a sixth step of combining by the calling phone number and the recipient, the characterized in that the third step and the fourth step and the fifth step and the sixth step are selectively performed respectively.

In addition, in order to achieve the above object, another embodiment of the routing table configuration method according to the present invention, the receiver telephone number by determining whether the caller's telephone number and the caller's telephone number dialed by the caller belong to the same Lata In order to determine Intra Lata and Inter Lata calls, LSC and Lata Code, which is a combination of Area Code and Prefixes, are included in the recipient's phone number. A method of configuring a routing table for the entire United States, comprising: a first step of mapping and registering a * and # code with at least one of a predetermined recipient phone number registered by a caller and a telephone number not using an access code for a long distance call connection; The second step of mapping and registering the access code for the exchange equipment of the international call provider and the International Dialing Prefix (IDP); The third step of mapping and registering the combined code of the service code and the service code and the # code, the fourth step of registering by registering the unique number of the carrier identification code (CIC) entered by the caller and the null, and the Easily Recorgnizable Code. ), The fifth step of selecting toll-free numbers, mapping them with null, and registering them with null, and the code that combines LCC for Lata area belonging to '1', which is ICC (International Calling Code) And a sixth step of inputting a Lata code for the first step, wherein the first to sixth steps are performed regardless of the order.

Further, in order to achieve the above another object, the user interface method of the auto-dialer according to the present invention, in order to define the operation of the auto-dialer according to the characteristics of each recipient telephone number. Each telephone includes a telephone number pattern field for storing a telephone number pattern value, which is a common code value of a recipient telephone number, and an execution rule field for storing an auto-dialer operation code for each telephone number pattern value. An auto-dialer user interface method comprising a database for mapping and storing an operation code to a number pattern value, the method comprising: a first step of receiving a receiver telephone number from a caller; According to the input order from the first input code, the telephone number with the same digit value as the input order of each code is the same as the code. A second step of retrieving the pattern value, a third step of retrieving the searched phone number pattern value until there is one, and an auto-dialer according to the operation code of the execution rule field mapped to the retrieved phone number pattern value And a fourth step of executing), wherein the second to fourth steps are performed during the execution of the first step.

Preferably, the third step is a step 3-1 of dialing an access number (AN) and a personal identification number (PIN) for the telephone company network when the operation code is a connection to a predetermined telephone company network, and the receiver; And step 3-2 of dialing each code of the remaining phone number being input from the caller among the phone numbers individually according to the caller's input. At this time, in step 3-1, it is preferable to mute the sound of dialing the AN and PIN.

Hereinafter, the terms used in the present invention will be described in detail with reference to the accompanying drawings.

1) Access Code

Refers to a spare telephone number that the user must dial to connect to a specific outgoing trunk group or line. Code of the same standard assigned by the telephone company to individual users in 101xx and 950-xx formats.

2) Area Code

Also called the Numbering Plan Area (NPA) in the United States. The first three digits of the telephone number represent the regional location of the telephone switch that provides telephone service. It represents a geographically defined area, distinguished by a unique three-digit code used in the North American Number Plan Area. [T1.207-1998] [T1.209-1998] Note 1: The defined geographic area is surrounded by the North American Numbering Plan Area (Code 800, 888, 877, etc.). It can represent the whole area. Note 2: Due to the advantages of overlay concepts deployed in several states, two (or more) NPAs may be assigned to the same defined geographic area.

3) Auto-Dialer

4) Circuit Identification Code (CIC)

A numeric code assigned by a North American Numbering Plan (NANP) operator to provide a selected switched service. The numeric code is unique to each entity and is used by the telephone company for routing the call connection to a trunk group called the entity to which the code is assigned. A 4-digit numeric code that controls the routing applied to the call connection by switching.

5) Competitive Local Exchange Carrier (CLEC)

It represents a new local exchange carrier attempting to compete outside the traditional operational domain. CLEC refers to companies that are competing with existing US local telephone operators by providing their networks and switching. The term was coined by the Federal Communications Act of 1996, enacted to promote competition between long distance and local telephone service providers, to distinguish existing local exchange operators, namely LEC and emerging competitors. . North American Telecom and Winstar Communications are examples of CLEC.

6) Dial Tone

A beep when you pick up the handset, indicating the tone applied to the dial telephone system where the equipment is ready to receive a dial or tone pulse.

7) DID (Directed Inward Dialing)

It is a form of service that allows internal call connections to reach specific PBX extensions without human relay.

8) Dialed Number Identification Service

Incoming phone number verification service. DNIS is a telephone service that provides the telephone number of the called party. This is a universal feature of 800 and 900 phone numbers (phones to which the recipient pays) in the United States. If you have multiple 800 or 900 phone numbers in the same location, DNIS will tell you what number the call was made from. DNIS is achieved by reading and displaying touch tone numbers (DTMF or MF numbers), or by passing them to a specially equipped destination that can be used to program a call center.

9) DTMF (Dual Tone Multi-Frequency)

Two elevations are signals on a telephone system consisting of different bands, and are mainly used to control telephone systems at remote destinations (e.g. ARS, IVR, RADIUS, etc.) at remote locations because the calls are delivered to the destination to which they are connected. Also called multi-frequency pulsing or multi-frequency signaling. In a telephone system, multi-frequency pulsing is used in which two specific voice band frequency combinations, one of four low frequency groups and the other four high frequency groups, are standardized.

Note 1: DTMF signals-unlike dial pulses-can pass through the entire connection to the called user, thus providing a variety of schemes for remote control after access (e.g. after a connection is established). Can be.

Note 2: A telephone using DTMF typically has 12 keys. Each key is matched with a different frequency pair. Each frequency pair matches one of the decimal or "#" or "*" symbols ("*" is reserved for special purposes).

10) Easily Recognizable Codes:

The ERC code is called when the second and third numbers of the area code are the same. The ERC represents a specific service (e.g., 888 for toll-free service).

11) Gateway

As a device for changing protocols, transmission speeds, codes or security systems so as to transfer information between devices connected to different types of networks, the present invention mainly provides switching equipment for connecting telephone users connected to a PSTN and an Internet line. it means.

12) International Calling Code

Also called International Dialing Code (IDC) or International Country Code (International Country Code). Phone codes commonly used for long distance calls in North America, and country codes in other countries.

13) International dialing Prefix (IDP)

This is the number that telephone subscribers should dial first for automatic delivery of international equipment when making international calls in the United States.

14) Incumbent Local Exchange Carrier

Companies that provide local telephone service represent companies that have emerged since the sale of AT & T's split. Long-distance operators and other telephone operators (CLECs) mostly borrow from ILEC's network to maintain their business. Representative operators include ILECs such as SBC, Bellsouth, Verizon and Qwest as of 2004.

15) Inter Lata call

Represents a telecommunications connection that originates in one LATA and terminates in another, or terminates outside of that LATA.

16) Intra Lata call

Indicates telecommunications occurring and ending within the range of LATA.

17) LATA (Local Access and Transport Area)

Represents a geographical division in the United States that allows LEC to conduct telephone and exchange business. Normally, ILEC is a standard for charging CLEC, which also means a call section that receives a low section rate proportional to distance or applies a flat or free rate. Call rates within Lata are typically very low compared to long distance calls.

Under the Modification of Final Judgment (MFJ) Convention, a diverted Bell Operating Company (BOC) represents a geographic area that is allowed to provide exchange telecommunications and exchange access services.

Note: Under the MFJ Convention, BOCs are generally prohibited from providing services that originate in one LATA and terminate in another.

18) North American Numbering Plan

The fair operator of the North American Numbering System (NANP) is called NANPA. NANP is a numbering system for the Public Switched Telephone Neteork in the United States and its territories, including Canada, Bermuda, many Caribbean countries, and Turks & Caicos.

19) PIN (Personal Identification Number)

A number used to identify the caller when connecting to a remote dial-up device, such as RADIUS, and typically requires more than six digits for security.

20) Prefixes

Also called Central Office Code, Interchange, or NXX. The first three digits of the seven-digit telephone number (NXX) are assigned to the user's telephone exchange service when dialed on a regional basis.

21) Primary Key

The primary key of the relationship table uniquely identifies each record in the table. Unique attributes can be guaranteed (such as social security numbers (SSNs) in individual record tables) or can be generated by a DBMS (GUID in Microsoft SQL Server). The primary key may be composed of a single attribute or a combination of a single attribute.

22) RADIUS (Remote Authentication Dial-In User Sevice)

A security service that authenticates and authorizes dial-up users. In general, although connected to an access server having a modem pool of an enterprise network, the present invention refers to a service unit connected to a circuit switch or a gateway to provide an authentication service.

23) Ring Tone

Also called audible ringing tone or audible ringing. In telephony, a signal, typically constituting an audio tone interrupted at a slow repetition rate, is used to indicate to the telephone caller that the equipment of the called party is receiving a ring signal. Note: An audible riinging tone may be generated by the service switch of the called party or by the service switch of the calling party, but not by the receiving telephone equipment.

24) Service Code

Because of the format, a service code, commonly called an NII code, is used to provide a three-digit dialing access special service. In the United States, the FCC manages the NII code and recognizes only nationally assigned 211, 311, 511, and 711. In some states, NII codes that are not nationally assigned are allocated locally, and these regional allocations can quickly disappear if national allocations are made. There are currently no business guidelines for the allocation of NII codes.

25) User Interface

In terms of information technology, a user interface includes an application or website, including any informational design designed to interact with people, such as display screens, keyboards, mice, light pens, desktop forms, colored text, and help. How to induce or react to an interaction. Arguably, the user interface may include aesthetics of the device's appearance, response time, and content provided to the user in the context of the user interface.

26) additional dial tone

Show all tones except dialtones and ring tones that occur to connect to long distance operators. For example, when an auto-dialer is used to connect to a long-distance operator's network, the auto-dialer dials an access number, and a beep signal indicates that the long-distance operator is connected. , A dialing PIN, an authentication confirmation sound, and the like, which is collectively named as an additional dial tone.

Hereinafter, with reference to the accompanying drawings will be described in detail the advantages, features and preferred embodiments of the present invention.

In order to implement the function of distinguishing Intra Lata and Inter Lata correctly from the Auto-Dialer, the process of the US telephone number system and the Auto-Dialer is first used. Should be understood. For example, the telephone system of the United States is as follows.

Example 1) General US Phone Number Configuration

As shown in Example 1, a US telephone number consists of 3 Digit's Area- Code, 3 Digit's Prefixes, and 4 Digit's random numbers, which is the current North American Numbering Plan (NANP). Can be changed as necessary.

Next, an operation process of the auto dialer will be described.

Auto-Dialer: 1) receives user input; 2) checks whether this number matches a particular record in a user-specified Order Group; and 3) if it matches, a predefined access code. ) Or access code and caller ID, if it does not match, only the caller ID is exported. For example, if you specify an access code of 1800-663-9898 for an ordering number beginning with 011 in the Order Group, 1) the user dials 011-822-553-4292, and 2) the dialer opens the Order Group table. 3) If there is 011 record, it will send access code 1-800-663-9898 of 011 record and 011-822-553-7292 with user input.

Therefore, adding a routing method to distinguish between Intra Lata and Inter Lata in the step 2) of the process can achieve the desired result.

The key to this work is the area code of the calling party number and the recipient number or the combination of area code and prefixes (hereinafter referred to as 'LSC, Lata-Smart Code'). If it belongs to Lata, it is judged as Intra Lata, and if it belongs to another Lata, it is called Inter Lata. An example thereof is as follows.

Example 2) Simple Intra Lata / Inter Lata Classification Using LSC

Assumption 1) Caller ID: 847-947-xxxx (Lata 358 Affiliate Number)

        To: 312-808-xxxx (Lata 358 Affiliate Number)

Assumption 2) Caller ID: 847-947-xxxx (Lata 358 Affiliate Number)

        To: 815-945-xxxx (Lata 358, 360, 364, 366 Affiliate Number)

Assumption 3) Caller ID: 847-947-xxxx (Lata 358 Affiliate Number)

        To: 310-787-xxxx (Lata 730 Membership Number)

Assumption 1 of Example 2 shows that the area code of the recipient number 312 is the unique area code of Lata 358, so that only the area code 312 belongs to the same Lata as the calling party number. It is easy to see that it is

Also, in Assumption 2), since Area-Code 815 of the calling number belongs to Lata 358, 360, 364, and 366, it must be analyzed until 815-945 before the number belongs to Lata 368. Inter Lata).

In Assumption 3), since 310 is the unique area code of the Lata 710, it is easy to distinguish the Inter Lata name by using only the area code 310.

As such, the method of classifying the calling number based on Lata is referred to as Lata-Smart Routing (hereinafter, referred to as 'LSR'). This method is based on the following four facts.

(1) For Intra Lata in Lata, CLEC pays ILEC a lower fee than flat or at least Inter Lata, regardless of area code. For Inter Lata outside of Lata, CLEC pays relatively high fees proportionally to distances to the contracted network providers (Long Distance / International Call Service Providers, ILEC or other CLEC).

(2) The administrative division of US telephone service is Lata, each with its own Lata Code. The features of the telephone numbers included in each Lata are described below with reference to FIG. 2.

In FIG. 2, Area-Code 224 is a unique area code of Lata 358, whereas Area-Code 815 is commonly used in Lata 358 and 366. In this way, an area code may belong to one or several Lata. However, the area codes 635, 657, 688, and 692 of Area-Code 815 in Lata 366 do not overlap with the Area-Code 815 Prefixes in Lata 358. As such, it can be seen that the combination of Area-Code and Prefixes is a unique number found for only one Lata.

(3) Since the Lata Code input to the Auto-Dialer is a simple administrative division, other unique numbers or symbols may be used instead of the actual Lata Code.

(4) The number of digits in the LSC is not fixed, because the number of digits in the prefixes that make up the LSC varies from case to case. For example, hypothesis 1) in Example 2 requires only 3 Digits of Area-Code, and in case of Assumption 2), all 6 Digits of Area-Code + Prefixes must be analyzed. Intra Lata) can be determined. Therefore, in order to create a routing table that can accommodate both hypotheses 1) and 2), various LSC records of 3-6 digits must be entered.

Hereinafter, a specific method of implementing the LSR will be described by way of example.

In order for a machine to operate, the data on which the judgment is based is first input, the software processes the data to produce an output, and then the software uses the output to control the hardware. In the present invention, data is user input (dialing), software is a routing table and LSR composed of LSC and Lata Code, and hardware corresponds to a dialer. An example of a process by which an LSR receives user input, compares it with a routing table, and then determines whether it is an intra Lata call is shown in FIG. 3. 3 is a diagram illustrating a routing process of an LSR based on a state, and illustrates a case where a different routing table is used for each state.

Next, a detailed method of configuring a table will be described.

Common sense, to determine if an outgoing call is an Inter Lata call across the United States, you need a table of 1 + LSCs for all US phone numbers. However, if the auto-dialer's memory capacity is not large enough to accommodate LSCs throughout the United States, it may be necessary to split this table by Lata or State. Therefore, I will explain how to configure the table according to three environments throughout the United States, State, and Lata. At this time, the input order of the table records does not significantly affect the performance of the LSR.

1. Using a different routing table for each Lata

An example of a routing table that varies by Lata is shown in FIG. 4. At this time, the table configuration method is as follows.

1) Enter * and specify the most frequently used calling number as the access code (ex. Specifying the customer service number of the calling party's telephone company).

2) Enter #, and assign frequently used calling number as an access code. Alternatively, you can specify a number that does not use (bypass) an access code for long distance access.

3) Enter 011 (IDP, International Dialing Prefix) and specify the access code for the international call operator's exchange equipment (RADIUS).

4) Enter the local service available number (ex. 411-telephone number guide, 911 emergency call) among the service codes, and specify the same access code + # as each number. At this time, the number ending with # is sent immediately without waiting for user input.

5) Enter 1010, a unique number for the Carrier Identification Code (CIC), and specify null so that the access code for long distance access is Bypass. In this case, when the user enters 1010, it means that the user selects another long distance carrier. Therefore, the existing long distance call access number should not be transmitted.

6) Select toll-free number among ERC (Easily Recorgnizable Code), and specify null so that access code for long distance access is bypassed. Because it is a toll free number, the caller does not have to work to reduce costs.

7) Enter only 1 + LSC record of Lata area where Auto-Dialer will be distributed and assign Null to each. If the user's input then matches one of these records, the dialer will send the call to the local operator exchange without sending an access code for the long distance call. In this environment, auto-dialers are distributed in units of Lata, so there is no need to refer to a separate Lata code. This is because all 1 + LSCs inputted to the table belong to the same Lata.

On the other hand, 1 + LSC records in this table do not need a Lata Code column. Therefore, it is more effective to add 1 + LSC records to the Order Group table used by the existing auto-dialers.

In addition, 1) to 6) in the above order are general input orders of Order Group records that can be arbitrarily input by an auto-dialer user, and are not records corresponding to the LSR table of the present invention.

Next, the LSR operation method will be described.

1) Each time a user receives a dialing, the auto-dialer checks the routing table to see if there is a 1 + LSC record that matches the user's input.

2) If a match is found, it is determined as Intra Lata and only the calling number entered by the user is sent or the access code specified in the record is sent.

3) If there is no matching record, it is determined as an Inter Lata call, and the access code + calling number of the long distance call access device is sent out sequentially.

2. In case of using different routing table for each state

An example of a routing table that varies by state is shown in FIG. 5. At this time, the table configuration method is as follows.

1) Create an Order Group table in the same manner as in 1) to 6) of the routing table configuration method that varies for each Lata.

2) One state in the United States usually contains more than one Lata. Therefore, the routing table of auto-dialers distributed by state needs a separate column to indicate which Lata 1 + LSC belongs to. Therefore, the routing table in this environment is independent of the Order Group table and consists of 1 + LSC column and Lata Code column, which are primary keys. In the records of this table, enter 1 + LSC of the entire state where the sender resides and the corresponding Lata code.

Next, the LSR operation method is as follows.

1) Each time a caller's dialing is received, the auto-dialer checks the routing table to see if there is a 1 + LSC record that matches the user's input. Records are found only if the source number is a number within the same State.

2) If a matching record is found, check that the Lata Code of this record and the Lata Code of the calling number are the same. This is a case where it is assumed that the user's Lata code is stored in another area of the memory. If no matching record is found, it means that the calling number is a number belonging to another state. Therefore, the calling code is determined to be Inter Lata, and the access code + calling number of the long distance call access device is sequentially sent.

3) If the above two (source and destination) numbers have the same Lata Code, it is determined as Intra Lata and only the calling number entered by the user or the access code specified in the record is exported. .

4) If the Lata code of the two numbers above is different, it is determined as Inter Lata and the access code + calling number of long distance call access equipment is sent out sequentially.

3. The same routing table is used throughout the United States.

An example of a routing table used throughout the United States is shown in FIG. At this time, the table configuration method is as follows.

1) Create an Order Group table in the same manner as in 1) to 6) of the routing table configuration method that varies for each Lata.

2) LSC is a unique combination of numbers throughout the United States, and because there are so many Lata in the United States, 1 + LSC belongs to any Lata in the routing table of auto-dialers distributed throughout the United States. You need a separate column to display the text. Therefore, the routing table of this environment is independent of the Order Group table, and is composed of 1 + LSC column and Lata Code column, which are primary keys, as they are distributed in state units. In this case, the table configuration is exactly the same as in the case of circulating a dialer in units of states, except that records of multiple states are entered in one table. In this table, enter 1 + LSC of the entire US Lata and the corresponding Lata code.

Next, the LSR operation method is as follows.

1) Each time the caller receives a dialing, the auto-dialer checks the routing table to see if there is a 1 + LSC record that matches the user's input. If the number is in the United States, it must be found in the table. If the number is overseas, the access code + calling number specified in the 011 record of the Order Group table will be sent in sequence.

2) Check that the Lata Code found in 1) above and the Lata Code of the user are the same. It is assumed that your Lata code is stored in another area of memory.

3) If the above two (source and destination) numbers have the same Lata Code, it is determined as Intra Lata and only the calling number entered by the user is exported or the access code specified in the record is issued. send.

4) If the Lata Code of the two numbers above is different, it is determined as Inter Lata call, and the long distance call access equipment + caller number is sent out sequentially.

The point that can reduce call origination cost in common in the above three environments is the method of determining Inter Lata call by comparing 1 + LSC of destination and originator-LSR. This effectively eliminates the unnecessary long-distance costs incurred by a normal auto-dialer incorrectly sending all calls to remote access equipment.

Hereinafter, the overall operating process of the auto-dialer including the LSR will be described.

First, a schematic operational process of the LSR model according to the present invention is shown in FIG. 7 is a flowchart illustrating a case of using a dialer installed with an LSR according to the present invention. Referring to Figure 7 will be described a schematic process of the LSR model according to the present invention.

The user subscribes to a local telephone service and purchases a prepaid card for long distance and international calls (ST200, ST205).

LSR according to the present invention is to distinguish the local, long-distance and international calls, and in case of local calls to relay the local call at the local (local) exchange at the time of joining, in the case of long-distance or international calls, the operator equipment (gateway or Long distance and international calls are relayed via long distance operator equipment (ST210 to ST225).

Next, the overall process of operating the auto-dialer when LSR is applied to the general auto-dialer using the Order Group table is described below.

[ LSR Whole process of Auto-Dialer applied]

Since the table configuration method of the entire auto-dialer operation process including the LSR (when circulating in units of Lata) is the same as described above, a detailed description thereof will be omitted. Hereinafter, the operation method of each step will be described.

The caller picks up the handset and starts dialing.

The Auto-Dialer searches the Routing Table for a record that matches the first digit of your input.

Assuming that a predetermined customer center number (a customer center number of a specific company) is specified as an access code of a record, if a user input is #, a long distance call access code + customer center number is sequentially transmitted. On the other hand, if not #, the next input of the user is compared with the routing table. At this time, if the calling party number belongs to the same Lata as the customer center number of the specific company, do not send the access code for long distance call access.

Assuming that a number frequently used in the * 1, * 2 format is entered into the Auto_Dialer, if the user input corresponds to the * 1, * 2, ..., * n format, enter the access code + dialing number for the long distance call. Send sequentially.

On the other hand, if the user input is not in the format * 1, * 2, ..., * n, then the sender's next input is compared with the records in the Routing table. At this time, if the matching number belongs to the same Lata as the calling party number, the access code for long distance call connection is not sent.

Assuming that special service numbers such as 911, 611, and 411 are registered in an auto-dialer, only this number is immediately sent if the user input corresponds to one of the service codes. On the other hand, if the user input does not correspond to a service code, then the input is compared with one of the LSC records registered in the routing table.

If the user input matches one of the LSC records, the Auto-Dialer determines the calling number as an Intra Lata call and terminates the Routing Table lookup. After that, the auto-dialer receives all the remaining input from the user and sends it in silent mode.

If the user input does not match any record in the Routing table, the Auto-Dialer will not call the dialing number at the end of the table lookup, rather than a special number or a stored speed dial number. The call is judged as a call, and the access code for long distance call connection is first silenced. After that, the auto-dialer collects all the remaining inputs (caller numbers) of the user and sends them silently.

If the call is connected to the destination and the call starts normally, or the destination is determined to be busy or the wrong number, the call is terminated immediately.

Normally connected call ends.

Hereinafter, to the receiver than when the auto-dialer is not used, as in the first and second use embodiments of the conventional auto-dialers shown in FIGS. 9 and 10. The user interface for shortening the call connection time to the receiver by solving the problem of additional call connection time will be described. In addition, when using the auto dialer, the user (sender) cuts off additional dial tone sounds other than white tone, dial tone and ring back tone so that the user (sender) This section describes a user interface that does not recognize the use of a dialer.

FIG. 11 is an exemplary embodiment of using an auto-dialer according to the present invention, and is a modified example of the second conventional embodiment shown in FIG. An example of using an auto-dialer according to the present invention will be described with reference to FIG. 11.

The caller first dials the recipient's number without determining whether to run the auto-dialer (ST600).

Unlike in FIG. 10, the auto-dialer no longer waits for the receiver to enter the phone number if the condition is satisfied compared to the embedded database every time the caller enters a single digit number. It is immediately driven (ST605).

Specifically, the caller inputs the telephone number of the receiver in order, and the auto-dialer compares the input telephone number with the database in the input order. If the matching data is found during the phone number comparison, the auto-dialer stops searching the database and starts immediately (ST610). 11 illustrates an embodiment in which the caller inputs '1-999-999-9999'. Therefore, in this case, the auto-dialer limits the search range to the second and third data of the telephone number pattern database at the moment '1' is input, and then matches data when '9' is input. Is determined to be the third data. Therefore, the auto-dialer stops searching and attempts to make a call to C network.

The Ato dialer dials the AN and PIN numbers to access the C telephone network to access the C telephone network (ST615 and ST620). At this time, the auto-dialer silently processes the sound of dialing the AN and the PIN, thereby preventing the user from recognizing that the auto-dialer attempts to connect to the auto-dialer.

Next, the auto-dialer dials the remaining recipient's number (99-999-9999) individually from the sender (ST625), in which case the auto-dialer is called by the caller. The ST620 is already connected to the network of the C telephone company before completing the phone number input, and the time can be shortened by quickly dialing the remaining phone number from the caller in the input order. After the user dials the recipient's telephone number, the user does not hear a dial tone again but hears the dialing sound according to his or her dialing.

The use embodiment according to the present invention shown in FIG. 11 may be applied to the following cases.

In the United States, as of March 11, 2004, ILEC may charge CLEC on a LATA basis. In the case of an INTRA LATA call (when the calling party number and the recipient number are in one LATA), ILEC charges a low call cost, so you can make cheap phone calls using ILEC's network. In the case of an INTRA LATA call (when the recipient's number and the caller's phone number are in different LATAs), the telephone cost can be reduced by selecting and using a relatively inexpensive network among various telephone providers. As a result, if the recipient's telephone number is an INTRA LATA call or an INTER LATA call, CLEC can provide a low-cost phone service.

As of March 11, 2004, there are 1 to 17 LATAs in the state. For example, the state of Illinois is divided into 12 LATAs. LATA, which is the largest city of 12 LATAs, belongs to Chicago and has about 6 area codes (area codes or NPAs). Of course, the number of area codes varies by state and by LATA size. To distinguish between INTRA LATA calls and INTER LATA calls in the US telephone number system, check the Area Code (NPA).

FIG. 12 shows another application example of the use of the auto-dialer according to the present invention, in which a caller dials a number in a different LATA. A description with reference to FIG. 12 is as follows.

The user dials the receiver's telephone number (1-224-XXX-XXXX) in order without determining whether the auto-dialer is driven (ST700, ST705).

The auto-dialer retrieves and executes phone numbers from the database in the order of input (ST710). First, if '1' is input, the auto-dialer limits the search range to the second to seventh data in the telephone number pattern database. Next, if '2' is inputted, the data satisfying this condition is only the seventh data, so the Auto-Dialer selects the seventh data and connects to the C telephone company network according to the execution rules. do.

In FIG. 12, the standard for selecting a carrier's network is LATA. As for Chicago, as shown in LATA in FIG. 12, the classification of LATA calls is almost always the area code. This is possible only with (Area-Code), and most of the Area-Code can also be judged by the first or second number. Therefore, it is possible to quickly search by applying the present invention can maximize the effect.

The faster the caller chooses which network the Auto-Dialer selects while the caller is dialing the recipient's phone number (that is, when the Auto-Dialer runs), the sooner the autodialer ( Compared to the case where no auto dialer is used, the time difference can be minimized or equalized.

If the criterion for selecting the telephone network of the telephone operator is set as LATA as shown in FIG. 12, the auto-dialer can determine the moment when the second digit is input from among the 11 digits of the receiver. While entering the nine digits, the Auto-Dialer connects to the selected telephone company's network and quickly dials the remaining recipient's phone number again, allowing the caller to enter the last digit of the recipient's phone number. The auto-dialer can make the number of the last recipient's phone number the same at the time of dialing. Thus, by selecting the network of the telephone operator based on the Lata (LATA) can maximize the effect of the present invention.

Comparing the use embodiment according to the present invention with the conventional use embodiment has the following differences and advantages.

First, when compared with the use example which concerns on this invention, and the conventional 1st use example shown in FIG.

1) The subject of selecting a telephone operator is different. That is, in the first embodiment of the conventional use, the user selects the operator's network, whereas in the present invention, the auto-dialer is connected to the telephone operator through a database embedded in the recipient number and the auto-dialer. You will choose the network yourself.

2) The timing of choosing a network for a telephone operator is different. That is, while the first embodiment of the related art determines which telephone company's network is already used before the user inputs the recipient's telephone number, in the present invention, it is determined after inputting the recipient's telephone number.

3) The connection time to the selected telephone network is shortened.

4) Auto-Dialer mutes the operation of dialing the recipient's telephone number and the sound of additional dial tones other than white tones, dial tones and ring back tones. The user hears the same sound as using a regular phone without an auto-dialer.

Next, when compared with the use example which concerns on this invention, and the conventional 2nd use example shown in FIG.

1) Auto-Dialer starts to run differently. That is, unlike the second conventional use embodiment which is driven when the recipient's telephone number is fully input, in the use embodiment according to the present invention, the auto-dialer immediately starts from the moment of entering the first digit of the recipient's telephone number. Start the drive. Therefore, the connection time to the receiver is much shorter than that of the conventional second use embodiment.

2) The connection time to the selected telephone network is shortened.

3) In addition, by muting all the added sound, the user hears the same sound as using a regular telephone while using an auto-dialer.

The caller environment to which the user interface described above is applied is classified into four types according to the physical connection method of the auto-dialer, which is illustrated in FIG. 13.

1) One-to-one connection between telephone and auto-dialer (Fig. 13a)

2) Connection of a plurality of telephones and a Multi-Control Dialer (FIG. 13B).

3) Connecting a Multi-Line Dialer between the private branch exchange (PaBX) and the trunk line or private branch station and the station (FIG. 13C).

4) Connect an Auto-Dialer between the Phone and DSL Modem (FIG. 13D).

Each connection method and caller environment will be easily understood by those skilled in the art with reference to the drawings, and thus detailed descriptions thereof will be omitted.

The dialers used for the physical connection in each environment are various, such as a single-line dialer, a multi-line dialer, and a multi-control dialer. However, in any environment, if the basic condition that the auto-dialer is located between the trunk line and the terminal (telephone) or between the trunk line and the private exchange or equivalent equipment is met, the user interface function of the present invention operates the same.

As described above, a call routing method and an auto-dialer for distinguishing between an Intra Lata call and an Inter Lata call according to the present invention. The user interface method of preventing the user from recognizing the use of the has the following effects.

1) General Auto-Dialer uses simple routing method such that all calls that start with a certain number are regarded as long distance call unconditionally, so even the Intra Lata call can be remotely located. Although there is a disadvantage in that unnecessary section fees are wasted by returning to the receiver of the same Lata area through the equipment of the operator, the auto-dialer applied with the LSR according to the present invention solves the above-mentioned problems. By accurately determining whether an outgoing call is an Inter Lata call and sending an Inter Lata call only to a long distance call connection device, the user can use a telephone service without wasting time and money.

2) As shown in FIG. 11, the auto-dialer compares the receiver's telephone numbers in the order of input and starts operation at the moment of matching the database with the condition value. By minimizing the time to access the operator's network, the user can provide the same interface as when the auto-dialer is not used by reducing the time difference that occurs when using the auto-dialer.

3) In addition, by muting all the additional dial tones that result from accessing the telephone network, the user can use an auto-dialer but not use an ordinary telephone without the auto-dialer. You will be provided with an interface.

While the preferred embodiments of the present invention have been described using specific terms, such descriptions are for illustrative purposes only, and it is understood that various changes and modifications may be made without departing from the spirit and scope of the following claims. Should be done.

A caller receives a recipient's telephone number dialed, a combination of '1', which is an International Calling Code (ICC), and an LSC, which is a combination of an area code and a prefix, among the recipient telephone numbers, and the Lata code. Code) and compares each record in the routing table generated for each state with the recipient's phone number. If the recipient's phone number belongs to the same RATA as the caller's phone number, it is determined as an Intra Lata call and the recipient's phone number. If the caller's phone number belongs to a different Lata call to distinguish between the Intra Lata call and the Inter Lata call that is determined to be an Inter Lata call As a routing method, A first step of receiving the receiver's telephone number dialed by the caller; A second step of retrieving a combination of an '1' and an LSC matching the called party's telephone number; A third step of determining an Inter Lata call if there is no record to be retrieved and combining the access code for long distance call access and the input recipient telephone number; A fourth step of determining whether a Lata Code of the retrieved record and a Lata Code of the caller's telephone number are the same; A fifth step of determining that the Lata code of the searched record and the Lata code of the caller's telephone number are the same and calling only the input recipient's telephone number by determining an Intra Lata call; And If the Lata code of the searched record and the Lata code of the caller's phone number are different, the Lata code is determined to be an Inter Lata call, and the access code for the long-distance call connection is combined with the input recipient's phone number. A sixth step of sending; Intra Lata call and Inter Lata call, wherein the third and fourth steps, and the fifth and sixth steps, respectively, are selectively performed. Call Routing Method To determine whether the called party's telephone number and the calling party's telephone number belong to the same Lata to determine whether the called party's telephone number is Intra Lata and Inter Lata, A method of constructing a routing table for the entire United States comprising a LSC, which is a combination of Area Code and Prefixes, and the Lata Code among numbers, A first step of mapping and registering * and # codes with at least one of a predetermined recipient telephone number registered by the caller and a telephone number not using an access code for accessing a long distance call; A second step of mapping and registering an access code for an exchange equipment of an international call operator and an international dialing prefix (IDP); A third step of mapping and registering a service code input by the caller and a combination code of the service code and # code; A fourth step of registering by mapping a unique number of the CIC (Carrier Identification Code) input by the caller and null; A fifth step of selecting and entering a toll-free number among Easily Recorgnizable Codes (ERCs) and mapping the null with a toll number; And A sixth step of inputting a combination code of '1', which is an International Calling Code (ICC), and an LSC for a Lata area belonging to all states of the United States, and a Lata code for each code; And the first to sixth steps are performed regardless of the order. In order to define the operation of the auto-dialer according to the characteristics of each recipient telephone number, the telephone number pattern field storing the telephone number pattern value, which is a common code value of the receiver telephone number, and the auto number for each telephone number pattern value A user interface method of an auto-dialer including a database for mapping and storing an operation code for each telephone number pattern value, including an execution rule field for storing an operation code of an auto-dialer, A first step of receiving a receiver's telephone number from the sender; A second step of retrieving a telephone number pattern value having the same number of digits as the input sequence of each code from the first input code to an input sequence for each code constituting the receiver telephone number; Performing a search until the searched telephone number pattern value is one; And A fourth step of executing an auto dialer according to an operation code of the execution rule field mapped to a retrieved telephone number pattern value; And the second to fourth steps are performed during the execution of the first step. The method of claim 8, The third step, A third step of dialing an access number (AN) and a personal identification number (PIN) for the telephone company network when the operation code is a connection to a predetermined telephone provider network; And And step 3-2 of individually dialing each code of the remaining phone number being input from the caller among the caller's phone numbers according to the caller's input. . The method of claim 9, In step 3-1, And a sound for dialing the AN and the PIN by muting the auto-dialer.
