PURPOSE: A business model by the harmony of an Internet phone and a mobile phone network is provided to interlock a conventional telephone and a PC and automatically perform the function of an Internet phone when a user holds a telephone and puts a calling number. CONSTITUTION: If a user holds a telephone(1) inputs a mobile phone number in case that a PC(3) and the Internet(5) are connected, the telephone(1) connects to the PC(3) through an interface device(2). The PC(3) connects to a DB server(6) through the Internet(5) and connects to a control DB server of a mobile phone company. If information about a telephone state, a current position, and a connection state of a subscriber is transmitted to the DB server(6), information is transmitted to the PC(3) and an IP(Internet Protocol) is transmitted to the PC(3) so that the PC(3) connected to the telephone(1) has an IP address for transmitting voice information, and performs a telephone call by a communication protocol. An interface device(7) converts a packet inputted through the Internet(5) to be suitable for the function of an MSC(Mobile Switching Center) and provides the converted data to the MSC. Since the data inputted in the MSC includes the state and position of a mobile phone, the PC(3) connects to the mobile phone.

Description

Business model by convergence of Internet phone and mobile phone network {New Business model by joined Internet-phone and Mobile-phone Network}

Internet phone has been rapidly developed since VocalTrack launched the first VoIP gateway in 1995.

In our country, Star No. 1 was launched in 1998 by phone-to-phone method, and afterwards, in January 2000, the dialpad was noticed when it launched a free internet phone service.

Also known as IP Telephone, this method modulates voice into a data signal and provides telephone service over an Internet line. To this end, the analog voice signal is digitized and the 64kbps signal is compressed to 5.3K, 6.3K, and 8K, and sent through the packet Internet network using a transmission standardization protocol such as H.323. Internet phone can be classified into three types, PC to PC, PC to PHONE and PHONE to PHONE, depending on the type of terminal used at both ends.

The technical principle of Internet telephony is based on voice encoding and compression function, real-time data transmission technology, packet recovery technology, gateway technology, etc. The encoding of voice information applies low bit rate, high compression rate, and high sound quality encoding for transmission without compromising quality. As the voice encoding technology, PCM, adaptive prediction coding, GSM (GLOBAL SYSTEM FOR MOBILE COMM), LPC (LINEAR PREICTIVE CODING), etc. are being used. Real-time transmission technology is mainly used since RTP (REAL TIME TRANSPORT PROTOCOL) has been recognized for Internet transmission quality since 1995.

On the other hand, the gateway implementation technology means to implement a gateway that is a network connection device for converting the analog voice information for transmission from the existing circuit switched network to the packet switched network.

The basic function of the gateway is the digital signal processor and performs voice compression and atmospheric cancellation using the compression algorithm in the gateway. Most Internet gateways work with two point-to-point connections, meaning that a compatible gateway is required at both ends.

By applying this function, up to now, internet telephones are used to connect some or all of the lines connecting the sender and receiver.

In PC to PC, the headset is connected to the PC and a dedicated program is used to make a call, but the server is located in the center for mutual calls, and the IP information for connection is provided by a service provider (eg net meeting). You need to turn on and be registered on this server to make a call.

The PC to PHONE method connects to the PC to PHONE Internet phone operator while the caller's PC is connected to the Internet, and the operator installs his gateway to the PSTN exchange in the area where the callee is located. By connecting the callee to the caller, the PC to PHONE service provider must bear the cost of in-house calling and gate maintenance.

PC to PHONE Internet phone has been offered free service since 2000, but it is continuously changing to paid service due to the limitation of advertising-based sales model, but many questions are raised about its profitability.

Services such as dial pads that are provided in Korea belong to this field, and services provided free of charge increase the cost burden of operators as the number of users increases.

The PHONE to PHONE method is further developed to connect the service provider by first inputting a specific number (service provider exchange) to the subscriber who applied for the service of this method, and the received call is connected to the gateway to the gateway of the called party area. It is a service that transmits packets and connects each other by calling the callee's telephone through local PSTN exchange again. It aims to realize low-cost long distance telephone service by using internet network between gateway and gateway.

As described above, the current Internet phone service has been provided by converting a part of the PSTN into the Internet network using a general PSTN phone or PC as a terminal.

The present invention invented a new Internet mobile phone sales model by devising a system that connects and extends the basic technology of the Internet phone to a mobile communication network.

Currently, the mobile phone network is building or leasing its own network separately from the PSTN network for each service provider, and based on the communication between mobile terminals (hereinafter referred to as mobile phones), it is possible to communicate with the mobile phone by adding an interlocking service with the PSTN network. Let

However, this scheme is incurring additional call cost through the PSTN network section. (Figure 4-3)

Most mobile operators now allocate a portion of their revenue (about 35%) to PSTN operators, allowing consumers to communicate with their cell phones over landlines.

In addition, calls between mobile phones with different operators (eg, 019 → 011) are divided by revenue sharing agreements between operators.

In other words, the mobile phone is a service provider (e.g. 019) designated by the caller's cell phone (e.g. 019) when the call is connected between subscribers in its own telephone network and 100% of revenue is connected to another mobile phone network (e.g. 011). Is a structure in which dividends are allocated to the call organizer.

For this reason, despite the deterioration in profitability, each mobile carrier is distributing its own mobile phone for free, and is constructing a sales strategy to take advantage of self-network mutual call and profit from other network callers.

On the other hand, when calling a mobile phone with a regular phone, unlike a direct call with a mobile phone, since a general phone is not under the control of a mobile operator (eg, since it is not defined as 019), it automatically serves as a terminal of KT. It is true.

Therefore, the call of a mobile phone in a regular phone (eg, 232-1234 → 011-XXXX), KT, the provider of the PSTN, serves as the host of the telephone connection and receives the revenue.

Based on the revenue sharing structure of the mobile communication service, the present invention devised a new mobile communication service sales model.

In other words, the convergence of the mobile phone network and the Internet phone network enables mobile phone operators to devise ways to reduce the cost of route and call arrangement through the PSTN network, which is burdened when calling a mobile phone from an existing phone, and to improve the existing phone into an Internet phone that automatically connects to a specific mobile phone operator. Has devised a new model that can dominate the cellular phone call market.

As a convergence technology of internet phone network and mobile communication network to bypass the PSTN network to the internet network when calling a mobile phone with an existing phone and to call only a specific mobile communication company with an internet phone,

Firstly, it connects the existing phone and PC at the minimum cost and automatically enables the Internet phone to be operated when the user picks up the phone and inputs a call number.

Second, the technology that provides the user with the same environment as the PSTN phone by automatically executing the software of the PC and transmitting the tone signal of the phone when the PC connected phone is picked up.

Third, a technology that informs the mobile operator gateway of the dynamic IP of the PC user in order to guarantee the connection at all times when the PC user using the dynamic IP is called by a mobile phone.

Fourth, the technology that the operator gateway and the PC inside the unauthorized IP or firewall can interwork.

Fifth, the interlocking technology structure that allows the phone connected to the PC to be called naturally by the PSTN network when the PC is turned off from the outside.

Sixth, the gateway technology that connects the packet data called by the Internet phone method to the mobile communication switch.

Seventh, the technology to directly connect the Internet phone to the base station where the mobile phone calls to reduce the network load of the mobile operator.

Eighth, the technology to implement the call start / end time, call history system from the user terminal to implement the billing system of the operator according to this model.

Ninth, technology of implementing subscriber registration authentication in connection with a connection box and a user's telephone number.

It is intended to realize the above technical matters in the present invention.

The function of Figure 1 is connected to the device interlocking the phone and the PC (Fig. 1-2) is a complete system diagram that can be connected to the mobile phone through the PC when the mobile phone call

1. New Mobile Communication Sales Model by Internet Phone (Internet Mobile Phone: IHP)

A. Telecommunications Operating Revenue Model to Date

Mobile service provider A (ex: 019) sells a terminal (e.g. 019-xxx-xxxx) that is set up to automatically connect to company A (for example, sales or use period), and distributes it free of charge.

1) A company's subscribers call (Fig. 4-4)

When a call from a subscriber of company A (caller) is received by a base station via company A's relay and the callee is a subscriber of company A (for example, 019-xxx xxxx), the call is directly performed by Connect call and call through repeater. All call charges shall be announced and owned by Company A.

2) When Company A's subscriber talks with another mobile company subscriber (Fig. 4-5)

When Company A's subscriber (e.g. 019-xxxxxxx) calls Company B's (e.g. 016-xxxxxxx), it connects to the local base station via Company A's repeater in the cell where Company A's subscriber is located and makes a call to Company B's regional base station. In this case, the company pays B a certain amount of money in connection with the call. That is, the more the call A from the A company's subscriber terminal, the more profitable the A company.

For this reason, each mobile operator is making efforts to increase the number of registered terminals.

3) A company's subscriber call on a regular telephone (Fig. 4-3)

In this case, the general telephone is connected to KT through the PSTN network, and KT connects the call to the A company's base station (or central station).

In this case, KT bills the subscriber to the landline phone and pays part of this amount to Company A (about 65%).

Therefore, in this case, the general telephone plays the same role as the designated terminal (for mobile communication call) of KT. As a result, the mobile communication service provider only strives to expand the call market by mobile phones, and the call call market by phones is dominated by KT.

This structure applies similarly when calling a phone with an A company's mobile phone, so you must pay KT a certain percentage of revenue.

B. New Mobile Sales Revenue Model (Figure 2)

In the new mobile communication sales model based on the Internet phone, the PSTN network section can be converted to a specific mobile telecommunications provider's Internet network in order to reduce revenue distribution loss due to the PSTN network dependency generated when the phone and the mobile phone are mutually called. Example: A) Substituting A, as well as reducing the cost paid to KT, calling other mobile operators (e.g. B, C, D) by phone, via other A carriers (B, C, D) Etc.), KT can absorb the revenue allocated from other mobile operators (caller dividend) to Company A.

To this end, a specific mobile communication provider (e.g., A) distributes a PC, a telephone, a connection switching device (Fig. 1-2), which is a PSTN interworking device, or an additional device including this function and registers it on the Internet, as shown in Fig. 2. Have the procedure and related software installed.

Certain carriers (eg, Company A) can benefit from the same distribution of their phones as device / SW distribution.

Therefore, A can expand the mobile phone call market and increase profits without making a large investment in existing equipment investments, so that call charges can be reduced to users.

The new mobile operating revenue model is described below (Figure 2).

First, the separate telecommunications carrier (IHP) based on this sales model is intended for the connection between the PC and the telephone and the internet phone S / W for telephone users (home and work) who have a PC connected to the high-speed network. (Free of charge) (At this time, the connection switching device and S / W are fixed to be directly connected to a specific mobile service provider.)

Users who do not have access switching devices can connect the headset to a PC, and the owner of the IP phone can use the service without connecting to the PC.

Second, the user who installed the free access conversion device and S / W automatically connects to the gateway of the specific mobile communication provider (eg 019) and the Internet phone when the mobile phone number is pressed, and the specific mobile communication service provider connects it through the mobile communication network. Charge a fee.

Third, at this time, since the call does not go through the PSTN network, it is not necessary to give a connection allocation dividend of the PSTN service provider. When a mobile communication call is made, the specific mobile communication service provider using the sales model takes over the role of the PSTN service provider. Can achieve the same increase in operating revenue without increasing the number of mobile phones.

Therefore, it is possible to further reduce the user fee (about 30%) and allow users to install a connection changeover device and software for free.

Fourth, since the free distribution access conversion device can be manufactured to less than 5000 won, the cost can be recovered when using 20-50 won currency on a three-minute basis.

Fifth, the import structure of this sales model is as follows.

end. Direct connection method (Fig. 3-1) IHP allows the use of this sales model and device, and directly connects to a specific mobile telecommunication company when a subscriber calls, so that a certain rate of billing from the specific mobile telecommunication company is available. Dividend to revenue

B, indirect connection scheme (Fig. 3a)

IHP establishes a separate server so that the user's PC can identify and manage the ON-OFF status and the current IP, inform the specific mobile service provider of this information, and receive a certain amount of revenue while implementing the call.

In this case, IHP may install a gateway to provide Internet phone service between subscriptions.

At this time, Internet phone service between subscribers through IHP can be called automatically through internet or PSTN regardless of whether PC of callee is on or off (periodic checking of subscriber PC status and PSTN automatic linkage structure of connection switching device) PSTN service provider can get call arrangement revenue as a separate telecommunication service provider, and subscribers can get profits of telecom fee according to call composition.

All. Direct-indirect mixing

The subscriber's mobile phone call is directly connected and other phone calls are made by IHP by indirect method, thereby reducing the work load of IHP and generating profit.

Sixth, the same revenue structure is possible because the call is made to the Internet / PSTN via IHP even when the subscriber calls by mobile phone.

2. The concept of operation based on the proposed model is shown in FIG .

end. Users can install and install free access switching devices and S / W, and receive a significant discount on mobile communication charges and PSTN telephony call charges (mobile communication 30-40%, PSTN 90%).

I. IHP continuously manages the subscriber's PC ON-OFF status and current IP address information, informs the current IP of the called party (phone) when the subscriber's call is requested, and enables Internet phone calls.

However, in case of the caller who is off the PC or the caller who is not subscribed, the telephone interworking is possible through the PSTN network through the gateway of IHP. In this case, the usage fee for using the PSTN network is notified to the subscriber of the call request. (In this case, there is almost no cost saving effect for the subscriber, but a natural PSTN connection is possible.)

All. As a terminal device of the designed system, the user can use the existing telephone, wireless telephone PC headset, etc. as shown in FIG.

la. If you install a connection switching device and S / W distributed by a specific mobile communication provider (ex: 019) and call a cell phone (ex: 018), if you pick up the phone and press the cell phone number, it is connected to the gateway internet phone of 019 and goes through the 019 exchange. The currency is established at the 018 exchange and billing is announced via 019.

hemp. In this case, the specific mobile communication service provider (eg, 019) receives a dividend according to the call arrangement from 018, thereby reducing the user's rate within this range.

bar. In this case, IHP receives a fixed rate of call arrangement charge from 019.

2. Technical invention for sales model implementation

end. Central Gateway Concentration Method (Figure 1)

In the present invention, two methods of connecting an Internet phone to a central gateway of a specific mobile communication provider and a direct connection to a base station or a repeater have been devised to implement a sales model.

The first method is easy to maintain and maintain due to the concentration of gateways, but the burden of the network increases when the call increases because it uses a dedicated network of a specific mobile communication provider.

In the second method, since the small gateway is directly connected to the base station or the repeater, the Internet network is used instead of the mobile operator's dedicated network. Therefore, additional network expansion is unnecessary due to the increase in the cellular phone call of the Internet phone.

This method interlocks the location information (relay or base station where the cell is located) of mobile subscribers managed by the mobile operator's central control station with IHP, and installs a gateway with IP in the base station or repeater and connects it to the Internet.

At this time, the IHP informs the caller's PC of the gateway IP of the area where the mobile phone is located so that the caller, the base station, or the relay period can be directly configured on the Internet phone.

The description of FIG. 1 is as follows.

PHONE to HANDPHONE, HANDPHONE to HANDPHONE when there is a method of using a mobile phone, the present invention will be described a method to call a mobile phone by a general telephone.

When calling a mobile phone by a normal telephone can be used only by the operator's network of the telephone network, but the present invention is connected to the connection switching device by holding a telephone and entering a mobile phone number when the PC and the Internet network is connected (Fig. 1-2) ) Is connected to the PC through the Internet and the PC is connected to the DB server (Fig. 1-6) through the Internet network to the control DB server of the mobile phone company, which calls the subscriber's phone status, current location, connection status, etc. If you send the information to the DB server, this information will be delivered to the calling PC and IP at the same time, so that the PC connected to the phone has an IP address that will deliver the voice information.

The device controlling this is performed by the interface device (Fig. 1-7). This function converts the data coming in through the internet network according to the function of the mobile telephone exchange and connects it to the mobile telephone exchange.

The data entered into the mobile telephone exchanger knows the status and location of the mobile phone, so it connects directly to the mobile phone. Therefore, the caller can talk to the mobile phone inexpensively using the Internet without using the telephone network (PSTN). It is a function of the present invention

The mobile telephone exchange is called at each base station. It handles the outgoing signal and has the function to connect with the central control function and the switchboard of the public telephone network so that all base stations can be operated efficiently.

Fig. 1-2 is a device for transferring information to a computer by controlling a state of a phone and separation of a phone signal, a hook monitoring, a ring monitoring, and a DTMF reception as a connection switching device capable of interlocking a wired telephone with a PC.

The connection switching apparatus of FIG. 1-2 can be developed in various forms. There are various types of control methods such as a control method by a sound card and a USB method, a control method by integrated into a telephone, and the like. All forms are subordinate.

1-7 is a device for interfacing a packet of a mobile telephone exchange and an internet network, and is an interface device for data linking with a fixed call line for transmission of voice signals and signal information. It uses C interconnect protocol and is configured to enable interoperability through inter-network connections.

1-9 is a base station, which has a function of connecting a terminal and a mobile telephone exchange, and includes a wireless transceiver, an antenna, a control device, a data terminal, and a power supply.

I. Gateway distribution method (install gateway to base station or repeater) (Figure 6)

Gateway decentralization is one of the ways to reduce the burden of new relay station installation and its cost. By installing a gateway that can be connected to each base station or repeater using a high-speed Internet network, it can be used more efficiently than a conventional mobile communication company separately installing and using data lines.

In addition, it can be a data distribution processing method when the amount of relay line data is exceeded and an automatic backup system system in case of data line damage. Since this technology uses the existing high-speed Internet network as shown in Fig. 5, the initial facility investment is small, and since the Internet network can be selected and used according to the amount of data, the cost per line can be efficiently used. The operation method is the same as the description of FIG.

In the future, when constructing a new network such as IMT2000, the concept of the present invention enables service by interworking an existing high-speed Internet network with a base station or repeater without investing in a high-speed dedicated network for additional IMT2000.

The effects of the invention can be classified into effects in terms of subscriber, operator, and national.

1. Effect from subscriber's perspective

-By using two communication paths with one phone, you have the option of multiple communication paths.

Currently, the only communication path provided by Korea Telecom is the only path to make a call from a landline phone to a mobile phone or a landline phone. In the case of using the service provided by the present invention, a route using a packet network provided by the service provider in addition to the conventional Korean communication route is provided at a lower price than KT.

-Inexpensive communication means can be secured and communication costs can be reduced through competition among operators. The service provided by the present invention is designed to be replaced by lowering the income of the Korean telecommunications side in the fee settlement system between the existing operators to secure a cheap communication path from the user's point of view. In addition, the price cut competition of KT is expected to begin, and users will have the opportunity to reduce basic communication costs.

-It extends from the voice-oriented communication path to the communication path capable of multimedia service. The service provided by the present invention is a service using a packet network, and various types of services can be provided than services by a voice channel of KT. These services are linked with IMT-200, CDMA data communication, etc., so that multimedia services can be linked with home or office computer equipment without additional costs or facilities.

2. Effect from the perspective of the operator

-New telecommunications market centered on operators will be formed.

The current market structure can be seen as a high-cost market centered on KT and mobile operators, low-cost markets such as resale using bypass lines and Internet phones using packet networks. The low cost market is not active due to the inconvenience of users having to press more buttons and the difficulty of using computer programs.

The service provided by the present invention will not only use the existing phone as it is but also maintain the telephone call method, thereby accelerating the market access of the user, and the existing low cost market will be reorganized around the service provider of the present invention.

-It is easier to secure customers than other operators due to low cost and multifunctional service.

It is possible to provide services such as voice, data, and image from the existing voice-based service, and the connection device for this can be supplied at low cost, thereby securing a large number of customers in a short time.

-It is easy to create new service with the service that packet network and computer interwork.

Not only the existing voice service but also all kinds of services that can be achieved through computer communication are possible, making it easier to create new services and to occupy market leadership compared to the existing telecommunication service providers.

3. Effects at the national level

-Advanced and advanced information and communication services

The existing voice-oriented communication service has developed into a service including data and multimedia, and has started an advanced communication service that has not been available in any country. As a result, Korea will be a world leader in telecommunications.

-Generated various sources of revenue nationally.

Leading high-end telecommunications services will lead to a variety of standardization and market orders, which will greatly increase national benefits. Korea is expected to generate various profit sources through the control of equipment market and service market through standardization activities such as connection equipment and connection protocols around the world.

-Early establishment of major leading technologies, and thus, technological independence in the field of IT and securing the status of technology guidance bureau. Various leading technologies linked to mobile terminals will be established early, and the settled technologies are based on the technologies serviced by the present invention. It will evolve into generations.

-Benefit from the effects of informatization in the real life of the people

The present invention will lead to a high-tech information society in which home and office mobile terminals are integrated as a follow-up service, and people will feel the convenience of informatization and have confidence in the government.

-If you use the concept of the present invention when constructing a new network such as IMT2000 in the future, it is possible to connect the existing high-speed Internet network with a base station or repeater without investing in a high-speed dedicated network for additional IMT2000.

This approach can reduce unnecessary investment at the national level and enable early entry into high quality services.
