The present invention relates to a call method switching method, and more particularly, to a call method switching method that enables switching between a video call or a voice call according to a user setting in a terminal.                         

In recent years, due to the rapid development of communication technology, a variety of user interface functions have been provided as a function of a mobile communication terminal, in which only a voice call between a user and a counterpart is available, is gradually expanded. In accordance with this trend, a communication method capable of voice, video, and data communication has been developed, and methods for enabling full-scale high-speed multimedia services have been continuously studied.

Therefore, the camera is mounted on the mobile communication terminal separately or internally so that the user's face image is taken in real time and transmitted to the other terminal in the current call connection state, and the image transmitted from the other terminal is confirmed through the mobile communication terminal screen. This allows you to make phone calls while looking at each other's faces.

However, in the video call method provided through the mobile communication terminal, it is difficult for the user to carry the mobile communication terminal and move anywhere, so that his current location is difficult to be photographed and transmitted at the time of incoming / outgoing call. For example, there may be a bathroom. In such a case, if the photographed image is continuously transmitted to the other party, the other party, which is the video caller, may be uncomfortable, and there is a problem that it is not appropriate as a telephone call manner.

In addition, when a call is received for a video call, the user must turn on / off the camera or set the call rejection according to the caller. Therefore, even if the user does not want to reveal his or her face to a specific caller or does not want to make a video call with the other party according to the situation, the user does not have to turn off the camera for the video call and makes a call so that his or her video image is transmitted to the privacy of the individual. Problem may occur.

For example, a user of a mobile terminal may be able to view his / her face even if a call is suddenly called from a lover but does not want to show his or her face. There was a problem that the display is displayed through the other party's terminal to be reluctant to make a video call.

As described above, when a video call is performed in a conventional mobile communication terminal, unlike a voice call, the video call is rejected for such a situation despite the fact that it is difficult to protect individual privacy. There was no other way to prevent video calls.

In addition, the conventional video call method employs a voice call method, and when a video call is received every time regardless of the user's situation, the user has to inconvenience or to switch to the voice call mode.

Accordingly, the present invention has been made to solve the above-described problems, and by setting in advance whether or not the video call can be received in accordance with a predetermined condition it is possible to switch between the video call or voice call according to the set conditions at the time of video call It is an object of the present invention to provide a method of converting a call method that enables it.

According to an aspect of the present invention, there is provided a method of switching a call method in a mobile communication terminal capable of a video call, the method for setting a video call rejection target for each phone number stored in the mobile communication terminal, and a call requesting a video call. Detecting incoming caller numbers when the incoming call is received; determining whether the detected caller ID is the object of the set video call rejection; Characterized in that it comprises a process of performing.

In addition, the present invention provides a method of switching a call method using at least one mobile communication terminal and a core network, wherein the core network receives and stores a video call restriction area, and when a call command is input from a calling terminal. Determining the location of the terminal; determining whether the location of the user terminal is located in the stored video call restricted area; and when the determination result is located in the video call restricted area, the user terminal enters the voice call mode. And converting the call to perform the call.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It is to be noted that the same elements among the drawings are denoted by the same reference numerals whenever possible. In addition, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

 The present invention implements a function that can be switched to the voice call mode when the user does not want a video call when the video call call. To this end, the present invention can be set through two methods when the user does not want a video call. First, in the first embodiment of the present invention, the mobile communication terminal user sets a video call rejection function for each caller number in advance so that a video call or a voice call according to the caller number can be performed. In addition, according to the second embodiment of the present invention, a video call or a voice call may be made according to the position of the user terminal when receiving a video call call by registering a predetermined position that allows the user to reject the video call function through the network.

First, the role of the entire mobile communication system in which a video call is made in a mobile communication terminal capable of a video call according to the present invention will be described.

Hereinafter, referring to FIG. 1, a mobile communication system for performing a call connection is to perform a call connection by connecting to a mobile communication terminal by wireless communication, according to an embodiment of the present invention, a counterpart terminal 100 for making a phone call. ) And the user terminal 110 that calls the call corresponding to the origination. 1 is a block diagram of a mobile communication system for providing a call mode of any one of a video call and a voice call according to a user setting according to an exemplary embodiment of the present invention.

The mobile communication system includes a counterpart terminal 100, a user terminal 110, a base transceiver station (BS) 115, a mobile switching center (MSC) 120, and a home location register (HLR). A home location register (125) and a mobile communication network (130).

First, the base station 115 is wirelessly connected to each terminal 100 and 110, performs communication using a wireless section with each terminal 100 and 110, controls a wireless link and a wired link, and the user calls while the user is moving. Perform a handoff function to maintain the persistence of the. The mobile switching center 120 interworks with other mobile switching stations to process an outgoing / receiving request such as a video call request from each of the terminals 100 and 110, and performs a query for the terminal user with the home location register 125. do.

The home location register 125 is a medium-class computer that mainly performs a function of managing a terminal user. The home location register 125 stores user information and location information of the terminal and may designate a path for an incoming call. Therefore, in the second embodiment of the present invention, the home location register 125 provides location information to determine whether the location where the terminal 110 is located is a point set to reject a video call as the user terminal 110 moves. do.

In the following detailed description, the base station / base station controller 115, the mobile switching center 120, and the home location register 125, which provide a mobile communication service with respect to a mobile communication terminal, are collectively defined as a core network 130. That is, in the present invention, a network for providing a mobile communication service to a mobile communication terminal is referred to as a core network 130.

As shown in FIG. 2, the mobile communication terminals 100 and 110 of the mobile communication system include a control unit 200, a memory unit 210, a wireless unit 220, a voice processing unit 230, and a display unit 240. ), And a key input unit 250.

Hereinafter, referring to FIG. 2, the role of each component of a mobile communication terminal performing a call mode according to the position of the user terminal 110 will be described. To this end, it will be described with reference to Figure 2 which is an internal block diagram of a mobile communication terminal capable of switching the call method according to an embodiment of the present invention. Here, the internal block diagrams of the respective mobile communication terminals 100 and 110 are the same.

Referring to FIG. 2, the controller 200 of the mobile communication terminal performs an overall control operation of the mobile communication terminal. In particular, in the first embodiment of the present invention, the control unit 200 controls the call mode corresponding to the caller number by checking the call mode stored for each caller number when the call is received. In other words, the controller 200 controls to make a voice call instead of a video call when the caller ID is not the target of the video call, and the video call is made only for the authorized caller number. To help.

In addition, in the second embodiment of the present invention, if a terminal user presets and registers an area, for example, a toilet and a workplace, where a video call is not possible using an additional function of the core network 130, a call for a video call When the call is received, the controller 200 controls the video call or the voice call to be performed in response to the message according to the location determination result provided from the core network 130. That is, the controller 200 receives a message provided from the core network 130, and performs a control operation based on the processing result of the received message through a predetermined process. Here, the predetermined process refers to a process for reading information on a communication method included in the received message, and the call mode of the mobile communication terminal is determined according to the read result.

As such, when the call is received, the controller 200 turns off the camera 260 for the video call mounted in the mobile communication terminal when the call is located in an area where the call is not a video call target or the video call is impossible. In contrast, when the video call is a target or located in an area where the video call is possible, the controller 200 turns on the camera 260 for the video call and controls the image to be taken.

By doing so, in the present invention, since a video call or a voice call is selectively performed according to a user situation when a call is received for a video call, the inconvenience of having to directly operate a mobile communication terminal according to the user situation can be reduced.

In addition, the memory unit 210 connected to the control unit 200 may include a read only memory (ROM), a random access memory (RAM), and a voice for storing a plurality of programs and information necessary for controlling the operation of the mobile communication terminal. Memory, etc. As described above, the memory unit 210 includes a program memory and a data memory, in which program data necessary for controlling the operation of the mobile communication terminal is stored, and in the data memory, during control or during a predetermined operation by a user. Save the generated data.

For example, the memory unit 210 stores data about a calling number for rejecting a video call input by the key input unit 250. Accordingly, the controller 200 may store the video call rejection list generated by listing the input call number for rejecting the input video call in the memory unit 210. That is, the user may set a video call rejection function for each calling number in advance, and when the incoming call is received for a video call, the user may make a voice call instead of a video call.                     

Subsequently, the wireless unit 220 transmits / receives an RF signal with the base station through the antenna ANT under the control of the control unit 200. The voice signal processor 230 connected to the controller 200 is connected to the microphone MIC and the speaker SPK, and outputs the voice signal received from the microphone MIC to the controller 200. The voice data input from the controller 200 is converted into an audible sound through the speaker SPK and output.

In addition, the display unit 240 receives and displays display data on key input data input from the key input unit 250 under the control of the controller 200, or displays an operation state and a plurality of information of the mobile communication terminal as icons and text. do. In addition, the display unit 240 allows the user to visually know the state in setting or driving a required function under the control of the controller 200.

In addition, the key input unit 250 includes various keys including a numeric key and a character key to provide the controller 200 with key input data input by the user. That is, the key input unit 250 outputs its own key input data according to the input of each key provided, and the key input data output from the key input unit 250 is applied to the control unit 200 so that such key input data is stored. It is detected that the key input data according to the key input, the control unit 200 performs the operation according to the result.

Next, a process of performing a corresponding call mode according to a user setting when a call is requested for a video call will be described. This user setting is a method of registering a target to reject a video call in a mobile communication terminal according to the first embodiment of the present invention and a video call using the additional function of the core network according to the second embodiment of the present invention. This is done by registering areas that are not made. That is, in the first embodiment of the present invention, one of a video call or a voice call is determined for each calling number, and in the second embodiment of the present invention, a call method is determined according to the position of a user terminal.

First, in the following description, a process of performing a call method set according to a calling number will be described. To this end, a control flowchart for performing a call mode by calling number according to the first embodiment of the present invention will be described with reference to FIG. 3.

Referring to FIG. 3, the control unit 200 receives a video call rejection object by dividing a video call allowance object and a rejection object in advance by a user when a call is received for a video call in step 300. A call mode is set such that a call is made or a voice call is made instead of a video call.

Then, the controller 200 determines whether there is a call call requesting a video call from the counterpart terminal through the core network 130 in step 305. If there is a call incoming request for a video call, the control unit 200 proceeds to step 310 and determines whether a call connection key for a call connection is input. When the call is connected as a result of the determination, the control unit 200 detects the other party's phone number, that is, the calling number, included in the message received through the core network when the call is received. Accordingly, the controller 200 determines whether the caller ID detected in operation 320 is included in the video call reject list stored in the memory 210. That is, the controller 200 determines whether the detected calling number is a video call permission target.                     

If the detected caller ID is a phone number registered in the video call rejection list, the controller 200 controls the call to be made in the voice call mode instead of not performing the video call in step 330. Then, the controller 200 determines whether there is a key input for ending the call during the voice call mode in step 335, and terminates the call if it detects that the call is terminated. Return to to perform voice call mode.

In contrast, when the detected calling number is a phone number not registered in the video call reject list, the control unit 200 proceeds to step 325 and recognizes that the detected calling number is a phone number allowed for video call. By controlling each component such as turning on, the call can be performed in the video call mode. Then, the controller 200 ends the call only when there is a key input for ending the call while performing the corresponding call mode in step 340.

As described above, the terminal user sets, in advance, a target for allowing a video call and a target for not allowing the call through a phone book in the terminal, and stores the setting contents. Determines whether the corresponding calling number is a video call target, and if the video call is not a target, the call method is automatically switched to a voice call instead of the video call.

Meanwhile, a process for performing a call mode according to a location of a user terminal according to a second embodiment of the present invention will be described below. To this end, a message flow diagram for performing a call mode according to a terminal location in a mobile communication system according to a second embodiment of the present invention will be described with reference to FIG. 4.

First, after receiving a caller's phone number from the caller, if the call connection key is pressed, the call is attempted to connect to the video call request message including the caller information. That is, according to a key input for calling a call for a video call from the caller, the counterpart terminal 100 generates a message indicating that there is a video call request to the core network 130 and transmits the generated video call request message.

As such, when the call connection key is input, as shown in FIG. 4, the counterpart terminal 100 requests a video call from the user terminal 110 to the core network 130 at step 400. ). In operation 410, the core network 130 checks the location of the user terminal 110 in association with the home location register. The core network 130 then proceeds to step 420 to determine whether the current location is a video call restriction area set in advance by a user in a predetermined database linked with the core network 130.

If it is determined that the user terminal 110 is located in an area where a video call is possible, the core network 130 proceeds to step 430 to perform a corresponding function according to the video call. Here, since the performance of the corresponding function between the core network 130 and the terminals 100 and 110 according to the video call is the same as the operation during a normal video call, a detailed description thereof will be omitted.

In contrast, when the current location of the user terminal 110 is a preset video call restriction region, the core network 130 transmits a voice call connection message to the other party, informing that the voice call is performed instead of the video call connection. At the same time, the core network 130 transmits a call reception notification message indicating that the call is received to the user terminal 110 in step 440. According to the message transmission, a channel is formed and a voice call is automatically performed between the counterpart terminal 100 and the user terminal 110 in step 460.

In the foregoing detailed description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention. For example, in the embodiment of the present invention, the call method is determined for each caller or user terminal location, but it will be appreciated by those skilled in the art that both methods may be applied at the same time. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by those equivalent to the scope of the claims.

As described above, according to the present invention, when a mobile communication terminal user does not want a video call when an incoming call is requested for a video call, the user may experience a violation of privacy caused by the incoming call of the video call through a predetermined setting. Checking a video call has the advantage of reducing the inconvenience of switching to a voice call if necessary.
