Description

SPECIAL NUMBER REJECTING SYSTEM USING SHORT MESSAGE SERVICE AND METHOD THEREOF}

The present invention relates to a specific number blocking system and method using a short message service. In particular, a user of a terminal other than a target terminal to which call blocking is to be performed to suppress a predetermined terminal from accessing a specific number may be implemented. Short message service to protect the users of the terminal to be blocked from being exposed to harmful information by providing call blocking service by others to register the phone number and access blocking phone number list of the terminal in the wireless system. It relates to a specific number blocking system and method using.

As the use of portable terminals is becoming more common, the degree of encroachment caused by portable terminals is increasing. The most representative of them is exposure to harmful information. In particular, curious children frequently access harmful numbers by accessing certain numbers (for example, 700 paid information services). This is a serious problem in which children exposed to harmful information, along with excessive communication expenses, can cause mental shock or confusion of values.

In addition, there is little means for preventing the connection (eg, a telephone room) to an unhealthy telephone number using a predetermined ordinary telephone.

In order to prevent access to a phone number that may contain such various harmful information, a conventional method is to use a 700 pay service limit function set in the mobile terminal itself. Therefore, access to useful information is also impossible.

Above all, since the password of the terminal can be easily changed by the user of the portable terminal, the limitation through the portable terminal is difficult to expect a substantial effect. In particular, even if the parent has blocked access to the child's mobile device, the child needs to know the password in order to use the mobile device, so the child can turn off the function. If you prove that you are a legitimate user, you can modify your password.

Alternatively, it is possible to apply for a service to a service provider that provides a harmful information blocking service and receive a harmful information blocking service for the corresponding terminal, but since such a service can be easily terminated by the terminal user, Hazardous information blocking methods are also difficult to achieve.

Therefore, the guardian of the terminal user who wants to block a specific phone number provides his / her mobile terminal with the blocked target phone number and the phone number of the target terminal on which the outgoing block is to be executed to the communication network. New systems and methods are needed to prevent access to telephone numbers.

As described above, the method for limiting the access phone number of the conventional mobile terminal may be set by applying a blocking phone number internally to the terminal or requesting a harmful information blocking service from a service provider using the terminal. It is difficult to set the rejected phone number arbitrarily by the user, and there is a fatal problem that it is difficult to achieve effectiveness because the setting can be easily released by the user of the mobile terminal.

In view of the above problems, the present invention provides a short message service by inputting a number of a target terminal to which a call blocking is to be executed and a list of phone numbers to which access is blocked by another person associated with the target terminal user to be blocked. By registering with the communication network, the terminal blocking the outgoing call is denied access to the telephone number at the communication network system level, and at the same time, the user of the target terminal to which the outgoing block is executed does not terminate the service arbitrarily. The purpose is to provide a specific number blocking system and method using a short message service to block more effectively.

The present invention for achieving the above object, the mobile terminal station for requesting the call blocking service and inputting the phone number and the blocking phone number of the target terminal to be blocked and transmitted to the short message service; A base station which connects a call by controlling communication with the mobile terminal station; A short message service processing station for analyzing a short message from the mobile terminal station; A home location register that stores and manages the location and status of subscribers and whether or not a registered user; A server for storing outgoing call blocking service information from the mobile terminal station for each user; The home location register is used to manage the execution of the service requested by the mobile terminal station, and by using the connection blocking information stored in the server to the stored blocked telephone number when a connection request is made by the target terminal to be blocked. And a control station for denying access to the network.

In addition, the present invention comprises the steps of the user inputs the phone number of the call blocking target terminal and the phone numbers to be blocked to the mobile terminal station and transmits the information to the communication network in a short message; The communication network receiving the short message analyzes the extracted message and extracts a list of the call blocking target terminal telephone number and the access blocking telephone number designated by the user only when the mobile terminal station determines whether the mobile terminal station has the requested service use authority. Storing on the server; When a call connection request is received from the call blocking target terminal, comparing with the access blocking telephone number stored in the corresponding server, denying access when there is a matching number.

With reference to the accompanying drawings, the present invention as described above will be described in detail.

1 is a basic configuration for implementing the present invention, a mobile terminal station 10 that can transmit the telephone number of the target terminal to be blocked and the telephone number to be blocked to the base station 20 by requesting a call blocking service as shown. ), A base station 20 that communicates with the mobile terminal station 10 to connect with an external telephone network, a control station 30 that controls the operation of the base station 20, and various mobile phone networks, An exchange office 40 capable of processing a home location, a Home Location Register (HLR) 50 that stores and manages the location and status of mobile subscribers and whether or not a licensee is present, and a subscriber's short message It consists of a Short Message Service (SMS) system 60 and a Public Switched Telephone Network (PSTN) 70 which is connected via the switching center 40.

Although not shown, a server having various user information databases is also connected to the wireless communication network system. In some cases, it may be present in the HLR 50, the control station 30 or the base station 20, but it is generally preferable to exist in the HLR (50).

The mobile terminal station 10 refers to various mobile communication terminals including a portable terminal. Herein, the mobile terminal will be described as an example.

The user of the mobile terminal station 10 prepares a list of phone numbers to be blocked from accessing the phone numbers of target terminals to be blocked by using their own terminals and transmits them to the wireless communication network through the base station 20. In this case, the short message service is used.

Therefore, the mobile terminal station 10 should provide a menu for applying for call blocking, through which a user can input and edit a phone number of a target terminal to which call blocking is to be executed and a phone number for blocking access. In addition, a function for providing the information should be provided, and a function for transmitting the information including the corresponding information in a short message having a predetermined service request field after recording is completed.

It is preferable that the telephone number to block the access can be set not only as a simple telephone number but also as a group of telephone numbers starting with a predetermined number.

The base station 20 receives the short message received from the mobile terminal station 10 and hands it to the control station 30. The control station 30 requests the SMS system 60 to analyze the message. When the SMS message is analyzed into various fields including the information, and the information is provided to the control station 30 again, the control station 30 determines whether the call blocking service request is made through the analyzed field, and if it is correct, the HLR 50 is determined. Authenticate your rights with If the user of the mobile terminal station 10 who requested the service through the authentication has the authority to use the corresponding service, the message field is analyzed. If a predetermined field is set, the user accesses the telephone number of the target terminal to be blocked from the message. Extract a list of phone numbers you want to block and store it in the server's database.

Subsequently, when an access request is received from the target terminal to which the call blocking is to be performed, the control station 30 makes a request to the HLR 50 and compares the access blocking phone number of the stored database with the currently requested phone number, and then connects if it matches. Block and informs the terminal of the blocking.

Therefore, the present invention has three steps. First, a user prepares a phone number list of a target terminal to which call blocking is to be executed using his terminal and a list of phone numbers to block access, and has a predetermined request field. Sending in a short message; When the communication network receiving the sent message determines that the message is a call blocking service request message, storing the information included in the message in a database through user authentication; When a connection request is generated from the target terminal to which the call blocking is to be performed, comparing the requested phone number with the stored blocked phone number list in the communication network and providing a rejection message to the requesting terminal while rejecting the connection if there is a match. Is made of.

Specific embodiments of each of the above steps will be described with reference to the drawings.

2 is a flowchart illustrating a process of requesting a call blocking service by a user using a terminal. As shown, first, a user enters a call blocking request menu included in his terminal and inputs and stores a phone number to be blocked.

Then, enter a list of access blocking phone numbers to prevent the terminal to be blocked from accessing, if you want to register only a specific number, enter a phone number in the normal input mode, and if you want to register a phone number group starting with a specific number Enter or select the number starting in the corresponding mode.

After inputting the blocked phone number list through the above process, press the save key to store the inputted phone number list.

In order to transmit the stored list to the communication network, the terminal performs signal processing such as request field generation and information field setting, and then generates a short message requesting the corresponding service and transmits the short message to the base station.

Now, the process of registering this in the communication network receiving the short message provided from the terminal will be described with reference to FIG. 3.

First, it is determined whether the message received from the terminal is a request message in the SMS system, and if not, performs a function according to it, and if it is correct, performs authorization of the sender through the HLR.

If there is no authority according to the result of the authority authentication of the user, the message is ignored and terminated. If the authority authentication is successful, the received message is analyzed to determine whether a predetermined message field exists. The predetermined message field means a field having information necessary for registration of the call blocking service, and if the corresponding field is present, the request message is determined to be a call blocking service request message that blocks transmission from a user designated number to a specific number. . After that, a list of the call blocking target terminal phone number and the access blocking phone number is extracted from the message and stored in the server of the system. The server may be included in the HLR.

Finally, the actual service implementation of the call blocking service registered in the system through the above procedure will be described with reference to the embodiment of FIG. 4.

As shown, the communication network that receives the call connection request message from the caller designated as the call blocking target terminal through the above-described step analyzes the received request message and extracts the access number field from the message.

The control station of the communication network requests the HLR and compares the access rejected telephone number list of the corresponding terminal stored in the server with the access number extracted from the message and performs normal call processing if there is no match, and if there is a matching number, Block the request message and send a reject message to the requesting terminal.

In this case, it may be divided into a case of checking whether all numbers match by using a specific number and a case of checking a number starting with a specific number. This may be selected according to the manner in which the user initially registered.

As described through the above-described embodiment, the present invention allows the other party, in particular, the parent, to apply for the call blocking service for the terminal of their children, rather than applying for the call blocking service through the target terminal to which the call blocking will be performed. It is possible to effectively suppress exposure to harmful information.

As described above, in the system and method for blocking a specific number using the short message service of the present invention, a person related to a target terminal user to which call blocking is to be executed wants to block the number and access of the target terminal to which call blocking is to be applied to his terminal. When the user enters a list of numbers and registers them in the communication network using a short message service, the terminal to which the call blocking is performed is denied access to the telephone number requiring the call blocking at the network system level, thereby making the call blocking blocked. Can effectively block harmful information by preventing the service from being terminated arbitrarily, and ultimately, the service providers who provide effective blocking services of harmful information can acquire differentiation and create economic benefits through the service. There is.
