Description

A DETERMINANT METHOD OF CHARGE DISCOUNTING OF ORIGINATING CALL IN FMS SERVICE}

The present invention relates to a fixed mobile substitute service, and more particularly, to a method of determining whether or not a charge discount for an outgoing call of a mobile terminal in a wired / wireless replacement service.

In general, a wireless communication system through a mobile communication terminal has a basic configuration in which a communication service is provided by a base station in a cell in which a mobile communication terminal is located, based on a cell formed by a base station.

Recently, a variety of wireless personal area networks (WPANs), which allow direct communication between mobile terminals without using separate relay devices such as base stations as wireless communication systems. Techniques are being proposed. WPAN refers to a communication network that has a relatively small number of personal terminals or home appliances as members within a narrow range of operation within 10 meters using a wireless channel. This communication is intended to replace wired wirelessly and is widely used in the wide field of near field communication. It is used. Representative technologies of WPAN include infrared communication (IrDA), Bluetooth, and wireless local area network (WLAN). Among them, Bluetooth is an unlicensed 2.4000 ~ 2.4835GHz ISM (Industrial, Scientific) , Medical) 79 channels are set up with a bandwidth of 1MHz and frequency hopping spread spectrum is used to transmit data while changing channel 1600 times per second. Accordingly, Bluetooth has an advantage of accurately transmitting data even in a noisy wireless environment during communication.

In a wireless access environment in which a short range communication technology such as Bluetooth is applied, a short range communication is performed between a mobile communication terminal and an access point within a short range communication area and provides various service functions. For example, a fixed mobile substitution service may be used to call a mobile communication terminal through an existing mobile communication network and use a discounted rate at a wired telephone level in a specific area such as a home or an office. That is, the access point is installed in the discount area desired by the user, and when the mobile communication terminal makes a call within the recognition radius of the access point, the mobile communication company is provided by discounting the call charge to the level of the wired phone.

However, the conventional wired / wireless replacement service has the following problems due to an access point installed to provide a service.

First, there was a problem in that wired / wireless alternative service was provided even in a non-legal service area by illegally modifying an access point. For example, illegally copying access points, one installed at home and the other installed at a company, etc., provides access to wired and wireless services in two regions with one access point, which provides discounts on call charges.

In addition, in installing and operating an access point, power is supplied through a portable power supply means (eg, a battery) to illegally move the access point even in a non-legal service area to receive a wired / wireless alternative service. There was a problem. In other words, the wired / wireless alternative service receives a discount on the call charge when the call is made within the recognition point of the access point. By using the access point, the access point is moved to a place where the access point is not a legal service area. You will receive a discount.

The present invention is to solve the above problems, in determining the outgoing signal of the mobile terminal in the fixed mobile substitute service, the access point (access point) after confirming whether the outgoing call in the access point (access point) setting area It is to determine whether the point has been illegally moved, and to provide a method for accurately determining a discount on the charge imposed on the call.

In order to achieve the above object, in the wired / wireless alternative service according to the present invention, a charging discount determination method of an outgoing signal may include determining whether an outgoing signal of a mobile terminal is a specific field value; If it is determined in the determination step that the value is a specific field, the latitude and longitude information of the cell ID according to the originating signal of the mobile terminal is transmitted to the fixed mobile substitute (FMS) server and compared with the latitude and longitude information of the cell ID registered in the FMS server. A request step of requesting confirmation that the latitude and longitude of the registered Cell ID are within an allowable range; And if the latitude and longitude information of the Cell ID according to the originating signal of the mobile terminal is determined by the requesting step to be within the allowable range of the latitude and longitude of the registered Cell ID, then the call by the originating call of the mobile terminal is received. And a generation step of generating charging discount information for discounting the charged charge.

Here, the outgoing signal of the portable terminal may be an outgoing signal of the portable terminal registered in the access point.

In addition, the latitude and longitude information of the Cell ID registered in the FMS server is characterized in that the latitude and longitude information of the Cell ID according to the first signal of the mobile terminal registered in the access point.

On the other hand, in the wired / wireless alternative service according to the present invention, the charging discount determination method of an outgoing call transmits an authentication code to an FMS (Fixed Mobile Substitute) server through an outgoing call of the mobile terminal, and determines whether it matches the authentication code managed by the FMS server. Requesting a first step; If it is determined in the first request step that the authentication code is matched, the latitude and longitude information of the Cell ID according to the originating signal of the mobile terminal is transmitted to the FMS server and compared with the latitude and longitude information of the Cell ID registered in the FMS server. A second request step of requesting confirmation whether the latitude and longitude of the registered Cell ID is within an allowable range; And if the latitude and longitude information of the cell ID according to the originating signal of the mobile terminal is determined by the second request step within the allowable latitude and longitude range of the cell ID, the call origination of the mobile terminal is determined. And generating a charging discount information for discounting the charges imposed on the currency.

Here, the authentication code included in the outgoing signal of the mobile terminal is provided by the FMS server, it is characterized in that it can be changed at any time.

In addition, the outgoing signal of the portable terminal may be an outgoing signal from the portable terminal registered in the access point.

In addition, the latitude and longitude information of the Cell ID registered in the FMS server is characterized in that the latitude and longitude information of the Cell ID according to the first signal of the mobile terminal registered in the access point.

In the wired / wireless alternative service according to the present invention as described above, the method for determining the charge discount of an outgoing call has the following effects.

First, it is possible to determine whether to use an illegally copied access point or to send an access point illegally, thereby preventing unauthorized use of the access point.

Second, it is possible to prevent fraudulent use of the access point, it is possible to precisely the billing discount imposed on the call by the outgoing call in the wired and wireless alternative service.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the method for determining the charge discount of an outgoing call in the fixed mobile substitute service according to the present invention as described above will be described in more detail.

Example 1

FIG. 1 is a flowchart illustrating a method for determining a charge discount of an outgoing signal in a wired / wireless alternative service according to Embodiment 1 of the present invention. Referring to FIG.

1. Judgment step <S101>

The mobile communication network determines whether the signal originating from the mobile terminal is a specific field value. The reason for determining whether the value is a specific field is to determine whether the originating signal of the mobile terminal is transmitted within the wired / wireless alternative access point (hereinafter referred to as 'FMS AP') setting area. In order to determine this, a specific field value should be set between the mobile terminal and the mobile communication network. The specific field setting method is to set a specific value in some fields of a message determined on the protocol of the mobile terminal and the mobile communication network. That is, when the call originating to the mobile terminal having a specific field value is transmitted to the mobile communication network, the mobile communication network determines that the mobile terminal is transmitting in the FMS AP setting area.

Here, since the wired / wireless replacement service is provided when the mobile terminal is registered with the FMS AP, the outgoing signal of the mobile terminal is preferably the outgoing signal by the mobile terminal registered in the FMS AP, and the mobile terminal registered in the FMS AP. Whether or not the call originated by the FMS AP can be confirmed by searching whether the mobile terminal is registered through the call signal of the mobile terminal and notifying the mobile terminal of the search result. On the other hand, the FMS AP is provided with a software (S / W) for detecting the movement of the FMS AP according to the power supply, it can also control the operation of the FMS AP by detecting the movement itself when the FMS AP moves.

2. Request step <S102>

If it is determined that the originating signal of the mobile terminal is a specific field value in the determination step, the mobile communication network grasps the latitude and longitude information of the Cell ID according to the originating signal of the portable terminal and is identified to the wired / wireless alternative server (hereinafter referred to as 'FMS server'). The latitude and longitude information of the cell ID is transmitted, and a request is made to check whether the latitude and longitude information of the registered cell ID is within the allowable range compared to the latitude and longitude information of the cell ID registered in the FMS server. Here, the latitude and longitude information of the registered Cell ID is the latitude and longitude information of the Cell ID according to the first signal of the mobile terminal in the FMS AP setting area. If you install the FMS AP to receive wired / wireless replacement service and register the mobile terminal to be used for the installed FMS AP, the latitude and longitude information of the Cell ID according to the first signal of the registered mobile terminal is detected by the mobile communication network and transmitted to the FMS server. The FMS server registers the latitude and longitude information of the Cell ID according to the first signal of the mobile terminal. That is, the latitude and longitude information of the cell ID according to the first signal of the mobile terminal means the FMS AP installation location, and the FMS server determines whether the FMS AP is moved based on the latitude and longitude information of the registered Cell ID. When the first call to the mobile terminal after the installation, it is preferable to make the call from the FMS AP and the most close. In this way, by registering the FMS AP position in the FMS server through the first signal of the mobile terminal and later comparing the latitude and longitude information of the Cell ID by the signal of the mobile terminal, it is possible to determine whether or not the FMS AP is moved. It is possible to prevent the illegal use of the AP.

3. Creation step <S103>

Upon request of the mobile communication network, if the FMS server determines that the latitude and longitude information of the cell ID according to the originating signal of the mobile terminal is within the allowable latitude and longitude range of the cell ID registered in the FMS server, the FMS server responds to the originating call of the mobile terminal. Approve the discount of the charge on the mobile communication network for the charge charged to the call. The mobile communication network receiving the approval of the charge discount generates the charge discount information for discounting the charge charged to the call by the mobile terminal's call. In this case, the charge discount information is added to the call detail record (CDR). Is generated.

Example 2

FIG. 2 is a flowchart illustrating a method for determining a charging discount for an outgoing signal in a wired / wireless alternative service according to the second embodiment of the present invention. Referring to FIG.

1.First request step <S201>

The mobile communication network transmits the authentication code to the FMS server through an outgoing call of the mobile terminal, and requests a determination whether it matches the authentication code managed by the FMS server. Here, the authentication code is provided to the mobile terminal in the FMS server, when the user subscribes to the wired or wireless alternative service, the FMS server transmits the authentication code to the mobile terminal through the mobile communication network. The mobile terminal receiving the authentication code stores the authentication code in the memory in the mobile terminal, and when the mobile terminal storing the authentication code is sent, the authentication code is automatically transmitted to the FMS server through the mobile communication network. In this way, if the authentication code is transmitted to the FMS server and judged, it is possible to check whether it is an outgoing call by a mobile terminal subscribed to the wired / wireless alternative service, and whether or not it is an outgoing call in the FMS AP setting area. It can be prevented from copying and using. In case of subscribing to wired / wireless replacement service and registering a mobile terminal to be used for FMS AP, the mobile terminal can be illegally duplicated when receiving a service.In this case, if a verification code is applied, only the mobile terminal to which the authentication code is granted is used for wired / wireless replacement service. Because it can be provided to be able to prevent the illegal use of the mobile terminal to be copied. On the other hand, the authentication code is managed by the FMS server and can be changed from time to time so that the changed authentication code is transmitted to the mobile terminal through the mobile communication network.

In addition, since the wired / wireless replacement service is provided when the mobile terminal is registered with the FMS AP, the outgoing signal of the mobile terminal is preferably the outgoing signal by the mobile terminal registered in the FMS AP. Whether or not the call originated by the FMS AP can be confirmed by searching whether the mobile terminal is registered through the call signal of the mobile terminal and notifying the mobile terminal of the search result. Here, the FMS AP is provided with software (S / W) that can detect the movement of the FMS AP, depending on whether the power supply, so that the movement of the FMS AP can detect the movement itself to control the operation of the FMS AP.

2. Second request step <S202>

If it is determined that the authentication code transmitted to the FMS server matches the authentication code managed by the FMS server, the mobile communication network transmits the latitude and longitude information of the Cell ID according to the originating signal of the mobile terminal to the FMS server and is registered in the FMS server. Compare with the latitude and longitude information of the cell ID and request the confirmation of the latitude and longitude of the registered cell ID. Here, the latitude and longitude information of the registered Cell ID is the latitude and longitude information of the Cell ID according to the first signal of the mobile terminal in the FMS AP setting area. After the FMS AP is installed in the service area to receive the wired / wireless alternative service, the mobile terminal to be used for the installed FMS AP is registered, and the latitude and longitude information of the Cell ID according to the first signal of the registered mobile terminal is identified from the mobile communication network to the FMS server. When transmitting, the FMS server registers the latitude and longitude information of the Cell ID according to the first signal of the mobile terminal. That is, the latitude and longitude information of the cell ID according to the first signal of the mobile terminal means the FMS AP installation location, and the FMS server determines whether the FMS AP is moved based on the latitude and longitude information of the registered Cell ID. When the first call to the mobile terminal after the installation, it is preferable to make the call from the FMS AP and the most close. In this way, by registering the FMS AP position in the FMS server through the first signal of the mobile terminal and later comparing the latitude and longitude information of the Cell ID by the signal of the mobile terminal, it is possible to determine whether or not the FMS AP is moved. It is possible to prevent the illegal use of the AP.

3. Creation step <S203>

Upon request of the mobile communication network, if the FMS server determines that the latitude and longitude information of the cell ID according to the originating signal of the mobile terminal is within the allowable latitude and longitude range of the cell ID registered in the FMS server, the FMS server responds to the originating call of the mobile terminal. Approve the discount of the charge on the mobile communication network for the charge charged to the call. The mobile communication network receiving the approval of the charge discount generates the charge discount information for discounting the charge charged to the call by the mobile terminal's call. In this case, the charge discount information is added to the call detail record (CDR). Is generated.

Meanwhile, FIG. 3 is a flowchart illustrating a process of providing a wired / wireless alternative service according to the present invention. The first and second embodiments will be described below.

First, the mobile terminal receives the wired / wireless alternative service subscription information from the mobile communication network by SMS. In this case, the subscription information includes information for providing the mobile terminal (for example, an authentication code) and information for registering the FMS AP with the mobile terminal (for example, a serial number of the FMS AP). The mobile terminal receiving the subscription information transmits the subscription information to the FMS AP to register the mobile terminal with the FMS AP, and when the registration is completed with the FMS AP, the mobile terminal first transmits the subscription information. The first mobile terminal sends an inquiry request to the FMS AP or a mobile terminal registered with the FMS AP, and by the inquiry request, the FMS AP searches for the registered mobile terminal and informs the search result.

. If the searched result is a mobile terminal registered in the FMS AP, the first signal is transmitted to the mobile communication network. In this case, the first signal is set to a specific field value or includes an authentication code so as to determine whether the FMS AP is transmitted within the FMS AP setting area. It is delivered to the mobile communication network. If the specific field value is set, the mobile communication network determines that it is in the FMS AP setting area and requests the discount determination decision to the FMS server.In the case of including the authentication code, the mobile communication network transmits the authentication code to the FMS server through the mobile communication network. It is determined whether the call originates in the FMS AP setting area by determining whether the authentication code is managed by the server, and then the charging discount is determined. At this time, the charging discount is determined by the latitude and longitude information of the cell ID according to the first call signal of the mobile terminal stored in the FMS server, and later compared with the latitude and longitude information of the cell ID according to the call signal of the mobile terminal (determining whether the FMS AP has moved). If the latitude and longitude information of the cell ID according to the first signal of the mobile terminal is not stored in the FMS server, the FMS server stores the latitude and longitude information of the cell ID according to the first signal and discounts the charge for the first signal. Accepting and transmitting to the mobile communication network generates the charging discount information based on the received information. Here, the charging discount information is generated by being added to a call detail record (CDR).

In this way, by setting a specific field value in the outgoing signal of the mobile terminal or including an authentication code, it is possible to check whether the mobile terminal is transmitting within the FMS AP setting area, and to prevent the illegal use of an access point. Based on the latitude and longitude information of the Cell ID, the installation location of the FMS AP is grasped so that the illegal movement of the FMS AP can be determined. Will be.
