Abstract

PURPOSE: A receiving restriction method is provided to simply request/cancel a receiving restriction service to a mobile communication system by operating a keypad in a mobile communication terminal, thereby freely using additional functions while power of the terminal is not cut off. CONSTITUTION: A user inputs a desirous state variable value(S100). A controller of a mobile communication terminal(200) reads a state variable value stored in a memory(S110), and compares the state variable value with the inputted state variable value(S120). If the two variable values are different, the controller changes the inputted state variable value to a new state variable value, and stores the changed value(S130). The controller transmits a state information reporting message including the new variable value to a mobile communication system(100)(S140). A base station of the mobile communication system(100) receives a wireless signal, and transmits the signal to an exchange(S200). The exchange reads the state variable value included in the reporting message, and stores the value in a memory(S210).

Description

Mobile communication terminal and incoming call restriction method, and mobile communication system and incoming call restriction service providing call restriction service {MOBILE COMMUNICATION TERMINAL CAPABLE OF REJECTING A RECEIVING CALL AND METHOD THEREOF CALL REJECTING SERVICE AND METHOD THEREOF}

The present invention relates to a mobile communication system and a mobile communication terminal, and more particularly, to a mobile communication terminal and a call restriction method capable of call reception, a mobile communication system providing a call reception service and a call reception service.

In general, a mobile communication terminal refers to a device that allows a mobile user to perform a call while securing mobility. However, there is a problem caused by the mobility of the mobile communication terminal. For example, you might hear a bell or vibrate when you don't want to answer a call or when you have a hard time answering a call. In this case, the user turns off the mobile communication terminal or removes the battery to block incoming calls from the outside so as not to ring the phone or vibrate.

On the other hand, the recent mobile communication terminal, similar to the basic communication functions such as voice / video call and data communication, similar to that used in PDA (Personal Data Assistance) such as electronic organizer, calendar, calculator, calendar, clock, contact management, memo, etc. There is also a trend towards providing additional features.

As the usage of the mobile communication terminal is diversified as described above, a situation arises in which a user wants to use only an additional function without using a basic communication function. For example, a test student might use a mobile phone as a calculator or a clock, but never want to receive a call. In addition, the user attending the conference will want to use only the additional functions such as clock, memo, contact management, and schedule management among the functions of the mobile communication terminal.

However, the conventional mobile communication terminal may be disturbed in terms of the use of the additional function by processing the incoming call unconditionally prior to receiving a call from the outside during the use of the additional function while the power is on. For example, if a call is received from the outside while a message is input to send an e-mail while using an Internet service provided by a mobile communication terminal, all incoming messages are deleted when the call is received. . That is, since the basic communication function is preferentially processed rather than the additional function, there is a problem that the use of the additional function is restricted or stopped due to a call made while using the additional function.

This occurs because the conventional mobile communication terminal, which is present in the base station service area and is powered on, is forced to receive an incoming call from the outside, so that the additional function and the basic communication function cannot be used separately.

In order to solve this problem, there is currently a service for disabling call reception by disabling call reception for a specific telephone number or making a terminal outgoing or incoming only, which is mostly implemented by a control algorithm in a base station or an exchange. In order to receive these services, users need to notify their mobile service company by telephone or e-mail or change their settings by accessing and logging in to the homepage via the Internet. There is a problem.

Accordingly, an object of the present invention is to solve the above-mentioned problems, and provides a mobile communication terminal and a call restriction method capable of limiting a call so that a call reception function can be easily restricted through a mobile communication terminal, and a call restriction service. The present invention provides a method for providing a mobile communication system and a call restriction service.

The state variable value stored in the memory may store various values related to the user or the mobile communication terminal 200 of the user, but in this case, a state indicating whether the user is restricted to the mobile communication terminal 200. The variable value is saved.

As such, the state variable value stored in the memory 101 is transmitted from the mobile communication terminal 200 through wireless communication. That is, the mobile communication terminal 200 transmits a status information report message including a state variable value, and the mobile communication system 100 receives a status information report message transmitted from the mobile communication terminal 200 and is included therein. The state variable value is extracted and stored in the memory 101.

The mobile communication terminal 200 also includes a memory 201 in which a state variable value indicating whether a call is restricted is stored. The state variable value may be changed by a user input.

Referring to FIG. 2, the mobile communication system 100 includes a base station 110, a base station controller 120, and a switch 130.

The base station 110 performs wireless communication with the mobile communication terminal 200, and the base station controller 120 performs control of the base station 110.

The exchange 130 is connected to the base station controller 120 to process call processing and supplementary services of the mobile communication service subscriber.

The exchange 130 is described on the assumption that the memory 101 is stored with a state variable value indicating whether the incoming call to the mobile communication terminal 200 is limited, but the technical scope of the present invention is not limited thereto. It may be provided in another device that performs a function related to a service.

Referring to FIG. 3, the mobile communication terminal 200 includes a duplexer 220, a wireless transceiver 230, a controller 240, a memory 250, a voice processor 260, a display 270, and a ring signal generation. The unit 280 and the keypad 290 are included.

The controller 240 controls the overall operation of the mobile communication terminal according to the embodiment of the present invention.

The duplexer 220 receives the radio signal received from the antenna 210 and outputs the signal to the radio transceiver 230, and outputs the signal output from the radio transceiver 230 through the antenna 210.

The wireless transceiver 230 transmits a signal received through the duplexer 220 to the controller 240 and outputs a signal output from the controller 240 to the duplexer 220.

The controller 240 analyzes and processes a signal received through the wireless transceiver 230. In particular, the wireless voice signal received in the call mode is output to the voice processor 260.

The voice processor 260 outputs the coded voice signal output from the controller 240 through the speaker 261, and receives a user's voice signal converted into an electrical signal through the microphone 262 to a corresponding code. After the conversion, the control unit 240 outputs the wireless transceiver 220.

The ring signal generator 280 outputs a ringing tone upon receiving a ring signal under the control of the controller 240.

The memory unit 250 stores a ROM (Read Only Memory: ROM, not shown), various telephone numbers, names, and the like in which a program storing control data necessary for the control unit 240 to perform overall control. And a non-volatile memory (not shown), and a random access memory (RAM) (not shown) for temporarily storing and processing data generated during the program control.

The memory unit 250 includes a memory 201 in which state variable values indicating whether a call is restricted to the mobile communication terminal 200 are stored.

The key pad 290 includes a call key for starting a call by performing an incoming call, an end key for ending a call, a function key for dialing, and the like, and generates a key input signal corresponding to a key input by a user. Transfer to the control unit 240.

The display unit 270 outputs a character or an image representing various operation states of the mobile communication terminal 200 so that a user can see it, under the control of the controller 240, and is typically made of a liquid crystal display. .

On the other hand, the state variable value stored in the memory unit 202 is provided by the mobile communication terminal 200 so that the user can easily change the user interface. The user interface may be implemented through a menu function using the display unit 270 or may be provided through a shortcut key using only the keypad 290. That is, when a user presses a menu key on the keypad 290 and the menu is displayed on the display unit 270, a menu item such as a state variable value input may be found to directly change the value of the memory 201. Alternatively, the state variable value stored in the memory 201 may be changed by a user directly inputting a special key such as '*' or '#' on the keypad 290 alone or in a combination thereof.

Hereinafter, a call reception method according to an embodiment of the present invention will be described with reference to FIGS. 4 and 5.

First, a process of inputting or changing a state variable value stored in the memory 201 of the mobile communication terminal 200 will be described. The user moves to limit the incoming function of the mobile communication terminal 200. It is assumed that the reception restriction service of the communication system 100 is already subscribed.

A user starts a user interface for inputting or changing a state variable value stored in the memory 201 using a menu or a shortcut key of the mobile communication terminal 200, and then inputs a state variable value desired by the user. (S100). At this time, the desired state variable value is a value that sets or releases the mode to limit the incoming call to the mobile communication terminal 200.

In more detail, when the user activates the user interface, the control unit 240 of the mobile communication terminal 200 displays a screen on which the state variable value can be input on the display unit 270, and displays a keypad ( The key input of the user through the 290 is accepted and temporarily stored in the memory 250.

Next, the control unit 240 reads the state variable value stored in the memory 201 (S110), and compares the state variable value input by the user in the step S100 (S120).

If the user input and the state variable value stored in the memory 201 are the same, the state variable value input process is terminated because there is no need to change the state variable value.

However, if the user variable is different from the state variable value stored in the memory 201, the controller 240 changes the state variable value input by the user to the new state variable value in the memory 201 and stores it (S130).

Thereafter, the control unit 240 sends a status information report message including the state variable value newly changed and stored in the memory 201 to inform the mobile communication system 100 that the state variable value indicating the incoming call restriction mode has been changed. It transmits to the mobile communication system 100 (S140). That is, the controller 240 wirelessly transmits the status information report message to the base station 110 of the mobile communication system 100 through the wireless transceiver 230, the duplexer 220, and the antenna 210.

Next, a process of inputting or changing a state variable value stored in the memory 101 of the mobile communication system 100 will be described.

In step S140, when the mobile communication terminal 200 wirelessly transmits a status information report message including the changed state variable value, the base station 110 of the mobile communication system 100 receives the wireless signal and receives the base station controller. Transferring to the exchange 130 through the 120 (S200).

When the exchange 130 of the mobile communication system 100 receives the status information report message including the status variable value from the mobile communication terminal 200, the switch 130 reads the status variable value included in the status information report message and is located in its own database. Stored in the memory 101 (S210). In this manner, the state variable value indicating the incoming call restriction mode for the mobile communication terminal 200 is newly changed in the memory 101.

Next, a process of processing an incoming call according to the state variable values stored in the memories 101 and 102 will be described.

First, when a call setup request for the mobile communication terminal 200 is received from the outside (S300), the exchange 130 of the mobile communication system 100 is stored in the memory 101 in association with the mobile communication terminal 200. The state variable value is read (S310).

Thereafter, the state variable value is analyzed to determine the incoming call restriction mode for the mobile communication terminal 200 (S320).

If the state variable value stored in the memory 101 is set to the mode for limiting the incoming call to the mobile communication terminal 200, the exchange 130 cancels the call setting requested for the mobile communication terminal 200 ( S330). Therefore, in this case, since the requested call is not transmitted to the mobile communication terminal 200, the user of the mobile communication terminal 200 may not be prevented from using the additional function due to an external telephone. In addition, even in a situation where it is difficult to answer a call, only the keypad 290 may be used to limit an external call request.

However, if the state variable value stored in the memory 101 is not set to the mode for limiting the incoming call to the mobile communication terminal 200 in the step S320, the exchange 130 is the base station controller 120 and the base station ( The call message is wirelessly transmitted to the mobile communication terminal 200 through 110 (S340).

Next, the mobile communication terminal 200 receives and processes a call message transmitted from the mobile communication system 100.

In more detail with respect to this operation, the control unit 240 of the mobile communication terminal 200 is the base station 110 of the mobile communication system 100 through the antenna 210, the duplexer 220 and the wireless transceiver 230. In step S400, a call message transmitted wirelessly is received.

Thereafter, the controller 240 outputs a ring signal to the ring signal generator 280 to generate a ringing tone and displays a message indicating that a call has come to the display unit 270. In this case, the ringing tone may be a ringing sound or a vibration according to a user's selection.

On the other hand, when the user receives a ring tone in his mobile communication terminal 200 and the user presses a call key through the keypad 290 to make a phone call, the controller 240 wirelessly reports this fact. After transmitting and receiving to the base station 110 of the mobile communication system 100 through the transceiver 230, the duplexer 220 and the antenna 210 to set the wireless communication path to enable the call (S410).

As such, when the call path with the call request counterpart is established, the user performs a phone call through the speaker 261 connected to the voice processor 260 and the microphone 262 (S350 and S420).

Although the present invention has been described with reference to the most practical and preferred embodiments, the present invention is not limited to the above disclosed embodiments, but also includes various modifications and equivalents within the scope of the following claims.

According to the present invention, since the user of the mobile communication terminal 200 can easily request / cancel the incoming call restriction service to the mobile communication system 100 by operating the keypad 290, It provides convenience that freely use additional functions without power off.
