A method and a mobile communication terminal to which the method is applied.

Due to the development of mobile communication service, the advertising cost is low because the advertisement message is transmitted directly to the individual through the mobile communication terminal, that is, the text and voice message, rather than the advertisement using the mass media. In addition, since the advertisement can be selected by the consumer, the advertisement has a remarkable effect. For this reason, multimedia service providers or other service providers use random advertisements by extracting random numbers for the efficiency of advertisements, and requesting direct voice call connection or sending text messages to mobile terminals using the numbers. to be.

In particular, the above-described advertising method is a paid service provided by numbers beginning with 060, 0600, 0800, etc. The service amount is determined by the contractor, and information that can be used for payment of securities, fortunes, etc. per 10 seconds or 30 It will be offered for a fee per second.

Therefore, some operators, etc., use this number to induce a text message or voice message to win the event, or impersonate a friend, to call the number and inadvertently press the call button, or pay a large amount of information fee. You have a problem. In addition, service providers such as KT and DACOM are generally not responsible for excessive charges to the user according to the above-described service.

In order to prevent such a problem, users can apply for caller ID provided by the mobile service provider, and after checking the caller ID for the incoming call connection request, the caller ID service can be determined whether or not to connect the call. Is being provided.

However, even if the caller information service is applied for, caller requests from the additional service provider and random call connection requests from the other party are not checked by the user. Pressing a button has the problem of having to end the call connection process forcibly for the telephone connection.

Accordingly, the present invention is to solve the problem in the prior art, the user registration phone number to allow the user to block all call connection requests except for the call signal by the phone number registered as the call connection permission target of the mobile communication terminal It is an object of the present invention to provide a method for limiting the originating and receiving signals of a mobile communication terminal using the above method and a mobile communication terminal to which the method is applied.

1 is a view showing a schematic configuration of a mobile communication system for incoming and outgoing call restriction of the present invention. Referring to FIG. 1, the mobile communication terminal 100 receives a call channel through a call processing process of exchanging a message for call processing with a base station controller (BTS) 210 of the base station 200, and then moves to another mobile station. It connects to a communication terminal or a service server.

The above call processing will be described in more detail with reference to the CDMA scheme as follows. In the CDMA method, the mobile communication terminal sends a dialing signal message by the access channel to the base station, requests a call connection, and receives a channel from the base station. Next, the synchronization of the window center of the data to be transmitted is matched, and then the resources of the base station according to the call type are allocated to perform a voice call with the other party.

In the case of an incoming call, after receiving a page message from the base station and recognizing that there is a call connection request, the base station performs a response to the paging signal and then allocates channels to match synchronization and allocates resources of the base station according to the call type. After receiving, the preamble signal is transmitted to synchronize the synchronization, and after completing the call connection, a voice call or the like is performed.

Here, the mobile communication terminal stores a phone number allowed for call processing by an incoming / outgoing call as described below, and also forcibly blocks call processing for a phone number for which call processing for an incoming / outgoing call is not allowed. The start signal control unit 11 (see Fig. 2) is configured to include a detailed description of the mobile communication terminal configuration will be described in more detail with reference to FIG.

2 is a block diagram of a mobile communication terminal to which an embodiment of the present invention is applied.

As shown in FIG. 2, the mobile communication terminal 100 according to the present invention includes a call processing unit 12 that performs call control for connection with an external mobile communication terminal for voice communication and data communication of the mobile communication terminal. A control unit 10 including a ringer 14 for outputting a bellso, a signal processing unit 13 for converting a digital signal into an RF signal and converting an RF signal into a digital signal when there is an incoming signal in the call processing process, and a user interface Display unit 30 for outputting the screen, the output of the internal drive information, and audio unit 40 for processing and outputting an audio signal such as a voice signal or converting the audio signal input through the microphone into a digital signal and the user The keypad unit 50 for receiving a control command of the RF unit and the RF transmitter 60 for performing RF signal processing on the signal transmitted from the controller 10 to the outside and the RF signal received from the outside After performing the processing to convert the digital signal to the RF receiver 70 input to the control unit 10 and the RF signal transmitted to the outside or received from the outside by selectively switching the RF signal to be transmitted to the outside through the antenna It is configured to include a duplexer 80 for inputting the received RF signal to the RF receiver 70. Reference numeral 41 denotes a speaker, and 42 denotes a microphone.

In the above-described configuration, as a feature of the present invention, as described in FIG. 1, the permission target phone number of the incoming / outgoing call is stored in the form of a phone book, and call processing is performed after detecting the presence or absence of call control of the call processor 12. In progress, the call control target phone number is configured to further include a call signal control unit 11 for performing authentication on the incoming call by searching whether the phone number registered in the phone book. Here, the incident signal control unit 11 may be included in the control unit 10 or may be configured separately from the control unit.

In addition, the phone book and a user interface for outputting an interface screen so that a user can register and change a phone number that is a call signal target are stored in the storage unit 20.

The above-mentioned call signal control unit 11 registers a phone book for connecting an incoming / outgoing call by outputting an interface screen on the display unit 30 to register and update a phone number that is permitted to process an incoming / outgoing call in the phonebook. It also allows the user to make changes, and also allows the user to set up incoming call connection restrictions. In addition, a password may be set to drive the interface screen.

The above-described interface screen preferably includes a registration menu, an information change menu, and a call signal restriction setting function menu for registering a phone number permitted for call processing by the call signal, but is not limited thereto.

When the incoming / outgoing call restriction function is set by the user in the above-described configuration, the incoming / outgoing signal control unit 11 stores the caller information for the incoming / outgoing call or the phone number information that is the target of the incoming call each time the incoming / outgoing call is connected. Performs authentication to perform call connection when registered in the phone book by searching in the phone book. The call signal control unit 11 controls the progress and termination of the call connection process for the incoming / outgoing call according to the authentication result. When the call connection is blocked, a call release message is sent to the call processor 12 to the base station controller 210. Do it.

Figure 3 is a flow chart illustrating a process for limiting incoming and outgoing calls of the mobile communication terminal 100 using the phone book of the present invention. In the description of FIG. 3, a phone book for storing a phone number for which call processing is allowed for an incoming call is called a phone book. The interface screen for registering a phone number in the phone book is called a phone book interface.

As shown in FIG. 3, the process for limiting an incoming / outgoing call of the mobile communication terminal 100 using the phone book is an interface screen in which the call signal control unit 11 driven according to a user's driving command is stored in the storage unit 20. After reading the data and outputting it to the display unit 30, the user generates a phone book by registering a phone number that is the target of incoming and outgoing call permission through the keypad unit 50 and the interface screen (S10). Here, the user may set a restriction on incoming and outgoing calls other than the user registered in the width book through the phone book interface.

Thereafter, the start signal control unit 11 determines whether the call processor performs a call connection process based on a call signal received from a user or a hand signal received from the outside (S20).

If it is determined in S20 that there is no call processing by the call processing unit 12 for outgoing calls or incoming calls from the outside, the process proceeds to step S20 to continuously monitor whether call processing for the incoming call or incoming call is performed. If the call processing unit 12 performs the call connection process due to an outgoing call or an incoming call from the outside, the start signal control unit 11 is not connected to the phone number stored in the phone book by the user. It is determined whether the incoming / outgoing call restriction function for the phone number is set (S30).

As a result of the determination in S30, when the incoming / outgoing call restriction function is set by the user, the incoming call signal control unit 11 searches whether the caller information for the incoming call or the call destination telephone number for the incoming call is registered in the phone book 21. Perform authentication (S40). The authentication process of S40 determines that the authentication is successful if the target phone number of the incoming / outgoing call is stored in the phonebook, and that the authentication fails if it is not stored in the phonebook.

If the authentication is successful as a result of the determination in S40, the general call connection process as shown in FIG. 1 is performed (S90).

If authentication fails as a result of the determination in S40, it is determined whether the call is an incoming call or an incoming call (S50).

If it is determined that the call is S50, the call connection process is terminated by transmitting a message such as a call release to the base station (S80).

If the result of the determination in S50 is a hand signal, the mobile station transmits a message indicating that the call cannot be connected or transmits a message for notifying that the call is not performed from the server of the mobile communication provider to the caller terminal that has sent the incoming call. The call connection is stopped by transmitting a message for notifying that the call connection is terminated (S60) and then transmitting a call release message to the base station (S70).

In the process of S80 described above, when the call connection is forcibly terminated, the message output process of outputting a message indicating the end of the call connection may be configured through the display unit 30 and / or the speaker 41 of the user. have.

The present invention as described above allows the user to limit the incoming and outgoing calls using the mobile communication terminal, to solve the inconvenience of the user to perform unnecessary phone calls and release calls, parents can limit the indiscriminate calls of children. .

Therefore, the present invention described above provides the effect of saving the call charges in accordance with the restriction of the call and unnecessary call restriction of the children.
