The present invention relates to an incoming call control of a mobile terminal, and more particularly, to an incoming call control system and method of a mobile communication terminal capable of selective control of a call connection or an automatic response according to a receiver's selection. It is about.

In general, the mobile terminal is configured to notify the reception state by vibrating or ringing a bell or melody according to the vibration mode or the bell mode set when a call is received. When the vibration mode is set, the LED (Light Emitting Diode) installed on the outside of the main body of the mobile terminal blinks, and when a short message is received, a buzzer sounds and the LED installed on the outside blinks. You are notified of an incoming call status.

Therefore, in response to the above-described incoming call request notification, the user performs a call or activates the answering machine function and does not receive a call when unnecessary calls are required. At this time, the caller can only infer the caller's current situation in the three cases described above, and thus cannot send the caller's intention to the caller. As a result, the user has a problem in that the service means capable of responding to the incoming request is weak so that the called party's incapacity state cannot be delivered to the caller.

In addition, in recent years, when there is an incoming call in the mobile terminal, the user is notified of the incoming call by vibrating, or an alarm method for notifying the incoming call to the speaker when an alarm signal for an SMS or a call is received when the user is busy using an earphone. And the like are disclosed. Even in such a case, the called party needs a service means capable of responding to the incoming call request during a call. For example, when a conventional mobile terminal receives a call request by a caller in a call state, a short message (SMS) or an alarm signal for a call received by a third party is also output through a speaker mode in the same manner as a voice signal.

At this time, the speaker mode is in close contact with the user's ear during a call, and if an alarm signal is generated during a call, the alarm output through the speaker becomes strong enough to damage the ear of the user in the call. Conventionally, in order to compensate for the above disadvantages, the alarm signal is output through the vibration mode without using the speaker mode when the call is in progress. However, the control pattern that the called party can operate in response to the incoming call request is It is extremely incomplete.

In addition, the conventional mobile terminal detects when the user is using a earphone using a earphone, and controls to output an alarm signal not only in the vibration mode but also in the speaker mode. That is, when it is detected that the earphone is connected, the mobile terminal receives a signal corresponding to the earphone connection from the earphone connection part and switches the output path of the voice signal to the earphone. Therefore, the user is separated from the speaker for outputting the alarm melody, so that the call is made to the earphone without risk of damage to the ear, so that the alarm signal is output to the speaker. In addition, the vibration alarm is maintained even when the earphone is used by the user's setting.

In the above-mentioned call method, there is no control range that a called party can perform when an incoming call request is received, which causes the inconvenience that the called party must continuously receive the incoming request signal through speaker mode or vibration mode when an unnecessary incoming call is requested. Is caused. Therefore, there is a demand for a service in which a call control function for an incoming signal can be implemented in various ways regardless of the call state of the called party.

The present invention has been made to solve the above problems, and an object of the present invention is to allow the type of call connection according to the selection of the called subscriber so that the quality of the communication service can be improved. A call control system and method are provided.

According to a preferred embodiment of the present invention, the service system controls a call connection with the called terminal in response to a request by a call of a calling terminal, and receives a flash request signal for controlling incoming call from the called terminal. Receives and recognizes that the feature code (Feature Code) is included to request a feature request (Feature Request) to the home location register, and receives the incoming control signal included in the response of the feature request (Feature Request) to perform the incoming call control Destination exchanger; And receiving a feature request request from an incoming exchange, extracting an incoming call control mode corresponding to the feature code through feature code analysis, and including the incoming control signal according to the incoming call control mode. And a home location register for transmitting a feature request response.

In addition, the flash request (Flash Request) is a specific key signal transmitted from the called terminal, characterized in that a plurality of specific key signals are set for each service by the user or by the service operator.

In addition, the feature code (Feature Code) is a specific key used for additional service control, characterized in that generally starting with * or #.

On the other hand, in order to achieve the above object, a method for controlling an incoming call of a mobile communication terminal according to the second aspect of the present invention, in the method for performing an incoming call control for a called terminal, a) in response to a call request from a calling terminal Setting a call path to the called terminal; b) receiving a flash request signal from the called terminal; c) changing or controlling an incoming call setup for the called terminal by analyzing the flash request signal; And d) resetting the call path of the calling terminal according to the incoming call setting change or control.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in the present invention, when a specific key is assigned (defined) to a called terminal and an incoming call request is received by the called terminal, when the operation of the specific key is recognized, the called party can change the call connection type for the incoming call. To provide a service mode. For example, when a specific key is input from the called party, a pop up menu may be provided to selectively perform the auto answering function, the call waiting function, the VMS switching function, the call forwarding function, and the call release function.

1 is a block diagram showing an incoming call control system of a mobile communication terminal for implementing the above-described function. As shown in the drawing, the incoming call control system of the mobile communication terminal controls the call connection with the destination terminal 101 in response to a request by the call of the originating terminal 113, and receives the call from the destination terminal 101. Receives a flash request signal for call control and requests a feature request corresponding thereto, and receives an incoming control signal included in the feature request response to perform incoming call control. The incoming exchange 107 receives a feature request request from the incoming exchange 107 and extracts an incoming call control mode corresponding to the incoming call control mode. The feature request includes the incoming control signal according to the incoming call control mode. (Feature Request) includes a home location register 105 for sending out a response.

The flash request is a specific key signal transmitted from the called terminal 101, and a plurality of the specific key signals are set for each service by a user or by a service operator. The feature request is a signal that the exchange transmits to the home location register for the control of the additional service, and includes the control information in the response signal.

The home location register 105 is interlocked with a database 115 that holds an operation algorithm for each call control mode for a plurality of types of incoming call control, and the home location register 105 requests the feature request. And a matching algorithm for extracting an incoming call control mode corresponding to a feature code included in the feature code.

The incoming call control mode includes an auto answer mode, a call waiting mode, a call forwarding mode, and a call release mode. The auto answer mode is a mode for transmitting a pre-stored predetermined announcement to the database 115 for the caller's recording guidance, and storing the caller's voice to the called terminal 101. The call waiting mode is a mode for sending a call announcement for a caller to hold a call to the calling terminal 113 and executing a call connection after a predetermined time, for example, 10 seconds. The call forwarding mode is a mode for changing the called state. The first call forwarding mode connects the call of the calling terminal 113 to the called party's voice mailbox (VMS) and provides the called party's voice message to the caller. A second call forwarding mode for switching a call connection to a call forwarding number input from the terminal 101, a third call forwarding mode for switching a call connection to a call forwarding number previously stored by a called party, and a voice message of a caller A fourth call forwarding mode for storing as a mailbox is performed. The fourth call forward mode may be regarded as a quick voice service function. In addition, the call release mode is a mode for releasing the incoming call of the calling terminal 113 through a predetermined announcement.

Hereinafter, the main operation of the present invention will be described.

2 is a diagram illustrating a system flow of the present invention, and FIG. 3 is a flowchart for explaining a method of controlling an incoming call of a mobile communication terminal. As shown, in step S301 the calling terminal 113 requests the call path to the called terminal 101, in response to the calling exchange 111 through the home location register (HLR) or visitor location register (VLR) It connects with the incoming exchange 107. The originating exchange 111 provides the called terminal 101 information to the called exchange 107, and the called exchange 107 connects the incoming call to the called terminal 101 in step S303.

In step S305, the destination exchange 107 determines from the destination terminal 101 whether the service signal for the incoming call control, that is, the above-described flash request (Flash Request) signal is provided. The flash request signal is a plurality of key signals for incoming call control, and the called party can select a service based on a pop-up menu provided to the called terminal 101. For example, when an incoming call for a call request is connected to the called terminal 101 as shown in FIG. 4A, a pop-up menu is provided to the display window of the called terminal 101.

As shown, the pop-up menu may provide a menu such as an 'auto answering function', a 'call-holding function', a 'call forwarding function', a 'call release function', and the like. A specific key of the terminal 101 may be operated. Such a flash key may be, for example, an auto answer function selection # 3, a call waiting function selection # 5, a call forwarding function selection # 7, and a call release function selection # 9. And the like. Of course, the called party may select the corresponding menu using the selection button of the called terminal 101.

The destination exchange 107 receives a specific key signal provided from the destination terminal 101, that is, a flash request signal. The destination exchange 107 recognizes that the flash request signal is a feature code based on predetermined information. In step S307, the destination exchange 107 provides a feature request request including the feature code to the home location register 105. In step S309, the home location register 105 analyzes the feature code included in the feature request request. That is, the home location register 105 receives the feature code and analyzes it.

The home location register 105 holds analysis information for analyzing the feature code in the internal memory, and generates call control information corresponding to the feature code provided from the destination exchange 107 based on the analysis information. Here, the internal memory may be assumed to be a database 115 that cooperates with the home location register 105.

The home location register 105 enters step S311, and analyzes the feature code input from the destination terminal 101. Here, when the analysis result of the home location register 105 in the automatic response mode, step S325 is entered. The home location register 105 includes call answering control code corresponding to the answering machine mode to set the call connection control information. In this case, the auto-answer announcement broadcast code notifies the caller that the call can not be made at present, or notifies that the call with the called terminal 101 cannot be made, and is a comment for inducing the caller's voice recording. The above-mentioned voice recording of the caller is received and recorded by the voice recording apparatus of the called terminal 101 through the call exchanger 107.

In addition, the call connection control information is control information for connecting the call requested from the calling terminal 113 with the voice recording apparatus of the called terminal 101.

Thereafter, the home location register 105 enters step S339 and provides a feature request response to the destination exchange 107 including the auto-answer announcement code and call connection control information. After receiving the feature request response, the incoming exchange 107 enters step S341 to provide the announcement included in the feature request response, and calls the called terminal to record the voice to the voice recording apparatus of the called terminal. Connect it.

On the other hand, as a result of the determination in step S311, if not in the automatic response mode, the process enters to step S313 to analyze the feature code. When the analysis result of the home location register 105 is the incoming call hold mode, the home location register 105 enters the step S327 to set the call waiting announcement code and call connection waiting information, and then enters the step S339. A feature request response is provided to the destination exchange 107 including the auto-answer announcement code and call connection control information. After receiving the feature request response, the incoming exchange 107 enters step S341 to provide a call reception announcement broadcast included in the feature request response and suspends the setting of the call to the called terminal. After a predetermined time elapses or by a call connection request by a specific key operation of the called terminal, the call path between the calling terminal and the called terminal is connected.

In addition, as a result of the determination in step S313, if the call is not in the call pending mode, the process proceeds to step S315 to analyze the feature code. If the analysis result is in the call forwarding mode, it is determined whether the first call forwarding mode. As a result of the determination, in the first call forwarding mode, that is, when the call forwarding is performed to the called party's voice mailbox, the process proceeds to step S329 and the home location register 105 displays the VMS switching announcement broadcast code, the VMS access control information, and the VMS access number. After setting, the destination exchange 107 provides a feature request response. After receiving the feature request response in step S339, the incoming exchange 107 enters step S341 to recognize the VMS access control information, provides the VMS switching announcement included in the feature request response, and uses the VMS access number. Connect to your voicemail.

That is, the destination exchange 107 connects the one-way call with the calling terminal 113 to the voice mailbox VMS, and the caller sends the contents of the call to the voice mailbox VMS according to the guide message. Save it. Here, the destination exchange 107 may recognize that the storage of the caller's contents is completed, and may notify the destination terminal 101 of this.

On the other hand, if it is determined in step S315 that the home location register 105 is not the first call forwarding mode, it is determined whether the second call forwarding mode as in step S317. When the home location register 105 analyzes the feature code and recognizes the second call forwarding mode, that is, a command for diverting the call to a random number selected by the subscriber, the home location register 105 is the called terminal. The called party number received from 101 is extracted. In addition, the home location register 105 enters the step S331 to set the call forwarding announcement broadcast code, call forwarding access control information and call forwarding number to provide a feature request response to the call exchanger (107).

The second call forwarding mode described above is a mode for changing a call to a separate phone number while the called party is currently receiving an incoming call from the caller. Here, the phone number setting, the caller enters the number to be forwarded according to the guidance of the called terminal 101, select the call forwarding function as shown in Figure 4 (a), and then select the function for the incoming number input (# 73) ) Can be entered as shown in (b) of FIG. 4 or the corresponding function can be selected by moving the cursor. Here, the call forwarding number set by the called party is included after the feature code.

In step S339, the incoming exchange 107 receives the feature request response, and in step S341, recognizes the call forwarding access control information and provides a call forwarding announcement included in the feature request response. The call is forwarded to the call forwarding number using the call forwarding number. In this case, the called number may be a number of a wired telephone network or a number of a wireless telephone network.

As a result of the determination in step S317, if the second call forwarding mode is not present, the process proceeds to step S319 to determine whether it is the third call forwarding mode. If it is determined that the third call forwarding mode, that is, the called party wants to perform call forwarding with a preset phone number, the call proceeds to step S333 and sets the call forwarding announcement broadcast code, call forwarding access control information, and call forwarding number. The destination exchange 107 provides the feature request response.

Here, the preset call forwarding number is stored in advance in the home location register 105, and the call forwarding number may be a number of a wired telephone network or a number of a wireless telephone network.

After receiving the feature request response in step S339, the call exchanger 107 enters step S341 to recognize call forwarding access control information, provides call forwarding announcement included in the feature request response, and uses a call forwarding number. Connect the call to the forwarding number.

In addition, when the home location register 105 determines in step S319, if it is not the third call forwarding mode, it enters step S321 to determine whether the fourth call forwarding mode. As a result, if the call forwarding mode requested from the current called party is the fourth call forwarding mode, that is, to perform the quick voice switch, go to step S335 to enter the quick voice switching announcement broadcast code, quick voice switching control information and quick voice access number Set to provide a feature request response to the destination exchange 107.

After receiving the feature request response in step S339, the incoming exchange 107 enters step S341, recognizes the quick voice switch control information, provides the quick voice switch announcement broadcast included in the feature request response, and sets the quick voice access number. To connect the call to the QuickVoice server.

In this case, the quick voice switching means that the calling terminal 113 accesses the quick voice system and stores a voice message in a situation where the calling terminal 113 cannot make a direct call with the called terminal 101. It is characterized by passing directly. In other words, there is no need for a receiver to access his / her voicemail box and check the recorded voice message.

On the other hand, when the destination exchange 107 determines in step S321, if it is not the fourth call forwarding mode, it enters step S323 and determines whether the call release mode. As a result, when the incoming call control mode requested from the current called party is the call release mode, the process proceeds to step S337, sets a call release announcement broadcast code and call release control information, and provides a feature request response to the call exchanger 107. do.

The incoming exchange 107 enters step S339 to receive the feature request response, and then, in step S341, recognizes call release control information, provides call release announcement included in the feature request response, and releases the call.

As described above, the present invention allows the called party to control the incoming call connection to the called terminal, it is preferable that the calling terminal to listen to the ringing tone (coloring) ringtone tone.
