The mobile communication network is a communication network for communication between the mobile terminals and between the mobile terminal and the outside of the mobile terminal. The communication network is a communication network for communication between the first mobile terminal 100_1 and the second mobile terminal 100_2 ).

In addition to the call connection function, the mobile communication network can further perform a specific function of the mobile terminal such as tracking the location of the mobile terminal, setting the base station, and setting the route.

The first mobile terminal 100_1 may request the second mobile terminal 100_2 to establish a call connection. The first mobile terminal 100_1 may transmit a call connection request signal 11 to the mobile communication network 400. [

The second mobile terminal 100_2 can transmit a call connection request signal to the second mobile terminal 100_1 to the mobile communication network 400 simultaneously with the request for the call connection of the first mobile terminal 100_1.

The second mobile terminal 100_1 may request the first mobile terminal 100_1 to make a call connection to the first mobile terminal 100_1 at the same time as the call connection request of the first mobile terminal 100_1.

For example, when the first mobile terminal 100_1 and the second mobile terminal 100_2 terminate the communication due to the wireless disconnection during the communication, each terminal user can immediately redirect to the other party. That is, the first mobile terminal 100_1 may transmit a first re-issue request signal to the second mobile terminal 100_2, and the second mobile terminal 100_2 may transmit a second re-call request signal to the first mobile terminal 100_1 Lt; / RTI > In this case, the call is not connected due to a conflict caused by mutual call request.

In this case, the mobile communication network 400 may transmit the data burst message (DBM) to the first mobile terminal 100_1 and the second mobile terminal 100_2, respectively.

Each mobile terminal receiving the DBM message sets a call connection mode to either a call mode or a standby mode according to the control method of the MS according to an embodiment of the present invention, You can control the connection.

For example, the first mobile terminal 100_1 may be set to the calling mode, and the second mobile terminal 100_2 may be set to the standby mode.

For example, when the call connection mode of the first mobile terminal 100_1 is set to the calling mode by the above program, the call connection mode of the second mobile terminal 100_2 can not be set to the standby mode. Also, when the first mobile terminal 100_1 is set to the standby mode, the call connection mode of the second mobile terminal 100_2 is set to the calling mode.

Accordingly, the call connection between the first mobile terminal 100_1 and the second mobile terminal 100_2 can be connected due to operation in accordance with the established call connection mode.

The mobile terminal 100 may request the mobile terminal 100 to make a call while the mobile terminal 100 requests the mobile terminal 100 to make a call.

The control unit 180 can check whether the identification number of the external terminal included in the DBM received from the mobile communication network is the same as the calling number of the mobile terminal 100 at step S130.

If the numbers are the same, the controller 180 may determine a call connection mode of the mobile terminal 100 (S140).

That is, when the mobile terminal 100 and the external terminal simultaneously make a call connection request to each other, the call connection will fail. Accordingly, each terminal checks the DBM received from the mobile communication network and confirms that the calling number of each terminal and the number included in the DBM are the same as each other and confirms the call connection mode of the terminal to either the calling mode or the standby mode Setting.

5 is a signal flow graph illustrating a signal relationship between a mobile terminal, a mobile communication network, and an external terminal according to an embodiment of the present invention.

Here, it is assumed that the mobile terminal (A, 100_1) is A and the mobile terminal (B, 100_2) is B.

A 100_1 can transmit a call connection request signal to the B 100_2 in the mobile communication network 400 (S11).

Also, at the same time as the call connection request of the A 100_1, the B 100_2 can transmit a call connection request signal to the A 100_1 to the mobile communication network 400 in step S31.

The mobile communication network 400 can transmit the DBM to each of the mobile terminals A and B upon receiving the call connection request signal from the A 100_1 and the B 100_2 at the same time.

The DBM transmitted from the mobile communication network 400 to each of the terminals A and B may include an identification number (e.g., telephone number information) of the counterpart terminal.

For example, the mobile communication network 400 can transmit the DBM including the telephone number of the B 100_2 to the A 100_1 (S21), and the mobile communication network 400 can transmit the DBM including the telephone number of the A 100_1 DBM to B (100_2) (S22).

Accordingly, the A (100_1) can confirm that the B 100_2 requests the call connection through the information included in the received DBM, and the B (100_2) It can be confirmed that the mobile station 100_1 is requesting a call connection.

Then, the A (100_1) confirms whether the calling number (the identification number of B) matches the identification number (the identification number of B) included in the received DBM (S12) Number) and the identification number (identification number of A) included in the received DBM are identical (S32).

When the comparison between the numbers included in the DBM and the origination number is completed, A (100_1) and B (100_2) can respectively determine a call connection mode (S40).

For example, the A (100_1) can set the call connection mode to the calling mode (S13) and try to connect the call to the B (100_2) continuously. In addition, the B 100_2 sets the call connection mode to the standby mode (S33), terminates the call connection to the A 100_1, and accepts the call connection from the A 100_1 to the A 100_1, And B (100_2).

Accordingly, the A (100_1) user and the B (100_2) user can connect the call between the call A (100_1) and the B (100_2) at one time without repeated call connection attempt (S50).

On the other hand, if the number included in the received DBM is equal to the calling number, the mobile terminal 100 automatically sets the call connection mode to either the calling mode or the standby mode by a predetermined algorithm applied to an embodiment of the present invention It can be set to one mode.

Meanwhile, the mobile terminal 100 may provide a user interface that allows the user to enter a call connection mode by a user operation when the number included in the received DBM is the same as the calling number (see FIG. 6) .

6 is a screen configuration diagram illustrating an example of determining a call connection mode according to an embodiment of the present invention.

Referring to FIG. 6, the mobile terminal 100 can request a call connection to an external terminal and notify a user of a call connection request through a 'call connection' message 41. Also, the mobile terminal 100 can display the identification number "010-4736-3242" of the external terminal, which is the object of the call connection request, on the touch screen 151. [

As described above, when the external terminal requests a call connection to the mobile terminal 100 at substantially the same time that the mobile terminal 100 requests a call connection to the external terminal, the mobile terminal 100 And can receive the DBM from the mobile communication network 400.

If the identification number included in the DBM is the same as the calling number of the mobile terminal 100, the mobile terminal 100 controls either the mobile terminal 100 or the external terminal to operate in the calling mode, The user can provide an item 51 (Auto Connection) to the touch screen 151 to enter into a mode capable of controlling to operate in the standby mode.

As the item 51 is touched, the mobile terminal 100 enters the call connection mode and can set the mobile terminal 100 to either a call mode or a standby mode according to a predetermined criterion.

In the above description, when two mobile terminals request a mutual call connection, the mobile terminal enters a mode for determining a call connection mode using information included in the DBM received from the mobile communication network.

Hereinafter, after entering the mode for determining the call connection mode, the first mobile terminal can be set to the calling mode and the second mobile terminal can be set to the standby mode according to a predetermined criterion in more detail Explain.

7 is a flowchart of a method of controlling a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 7, the mobile terminal 100 extracts the identification number of the external terminal from the received DBM (S210).

That is, the mobile terminal 100 can confirm the telephone number of the external terminal included in the DBM.

Then, the mobile terminal 100 may compare its identification number with the extracted identification number of the external terminal (S220).

Based on the comparison result, the mobile terminal 100 can select either the call mode or the stand-by mode for the call connection mode (S230).

Of course, when the first mobile terminal is set to the calling mode, the second mobile terminal can be set to the standby mode.

Hereinafter, S220 will be described in more detail with reference to FIG.

FIG. 8 is a flowchart for explaining S220 shown in FIG. 7 in more detail, and FIGS. 9 to 10 are views for explaining the embodiments shown in FIGS. 7 to 8. FIG.

Referring to FIG. 8, the mobile terminal 100 may sequentially compare the identification number of the mobile terminal 100 with the identification number of the external terminal by digit (S310).

In general, the telephone number of the mobile terminal may have a unique number in the public switched telephone network and may be composed of a fixed number of digits. Therefore, the telephone number has a predetermined number of digits, and may include a number corresponding to each digit.

9, the first mobile terminal 100_1 having the identification number (IN) "010-4736-3242" (61) has the identification number (IN) "010-9189-9842 & 2 mobile terminal 100_2 at substantially the same time.

Each terminal transmits the call connection request signal to a mobile communication network and the mobile communication network can transmit a DBM including an identification number of a call connection target to each terminal.

The control unit 180 of the mobile terminal 100 may determine whether the telephone number of the mobile terminal 100 and the telephone number of the external terminal are the same for a specific digit (S320).

10, the telephone number "010-4736-3242" 61 of the first mobile terminal 100 and the telephone number "010-9189-9842" 62 of the second mobile terminal 100_2, . ≪ / RTI > It is also assumed that the second mobile terminal 100_2 is an external terminal.

First, the number (0) corresponding to the first digit (C1) of the first mobile terminal (100_1) is compared with the number (0) corresponding to the first digit (C1) of the second mobile terminal (100_2).

Since the numbers corresponding to the first digits C1 are the same in both terminals, the mobile terminal 100 can compare the phone numbers of the terminals with the next digits (S330).

Referring to FIG. 10, the numbers of the terminals corresponding to the first to third digits C1, C2, and C3 are sequentially 0, 1, and 0, respectively. Accordingly, the control unit 180 can compare the number of each terminal corresponding to the fourth digit C4.

As a result of comparison, the number corresponding to the first mobile terminal 100_1 is "4" and the number corresponding to the second mobile terminal 100_2 is "9". If the digits corresponding to the corresponding digits are different, the control unit 180 can confirm the magnitude relationship of the digits.

Accordingly, the controller 180 can check whether the identification number of the mobile terminal 100 corresponding to the specific digit is larger or smaller than the identification number of the external terminal (S340).

Then, if the identification number of the mobile terminal 100 corresponding to the specific digit is greater than the identification number of the external terminal, the mobile terminal 100 is set to the calling mode (S350), and if it is small, the mobile terminal 100 can be set to the standby mode ).

10, the identification number 4 corresponding to the fourth digit of the first mobile terminal 100_1 is smaller than the identification number 9 corresponding to the fourth digit of the second mobile terminal 100_2.

Accordingly, the first mobile terminal 100_1 sets the call connection mode to the standby mode, and the second mobile terminal 100_2 can set the call connection mode to the calling mode.

Accordingly, the first mobile terminal 100_1 and the second mobile terminal 100_2 can be connected to each other without a call collision.

Meanwhile, in the above example, a terminal having a large number corresponding to a certain number of digits is set to a calling mode and a terminal having a small number is set to a standby mode, but the present invention is not limited thereto. The process of setting the calling mode or the standby mode according to the magnitude relation of the digits corresponding to the specific digits may be variously modified.

Meanwhile, according to an embodiment of the present invention, if the mobile terminal 100 is set in the standby mode but does not inform the user of the standby mode, the user can attempt to connect a call again. In this case, a call collision phenomenon may occur again.

Accordingly, the mobile terminal 100 may provide a touch screen 151 with a user interface for identifying the result of setting the call connection mode.

11 to 12 are screen configuration diagrams illustrating an example of a user interface for identifying the call connection mode when the mode is set to the standby mode.

11, the control unit 180 of the mobile terminal 100 displays a message 63 informing that the call connection mode is set to the standby mode according to the control method of the mobile terminal according to the embodiment of the present invention And can be displayed on the screen 151.

Referring to FIG. 12, the controller 180 of the mobile terminal 100 determines whether a call connection is established according to a color of the touch screen 151 in a call connection state and a control method of the mobile terminal according to an exemplary embodiment of the present invention. The color of the touch screen 151 when the mode is set to one of the calling mode and the standby mode can be expressed differently.

Accordingly, the user of the mobile terminal 100 can easily determine whether the mobile terminal is in the calling mode or the receiving mode when a call collision phenomenon occurs with the external terminal.

The method of informing the user of the result of the setting of the call connection mode is not limited to the above-described example, and can be variously modified. For example, the control unit 180 of the mobile terminal 100 may determine the state of the current call connection mode of the mobile terminal 100 using an audio signal, a graphic object, or the like.

Meanwhile, when the mobile terminal 100 is in the calling mode, the controller 180 may control to continuously transmit a call connection request signal to the external terminal.

In addition, when the mobile terminal 100 is in the standby mode, the control unit 180 may block the call connection request to the external terminal, thereby preventing a call collision phenomenon.

In the above description, it has been assumed that the mobile terminal 100 and the external terminal store a program for setting the call connection mode to either the calling mode or the standby mode when the above-mentioned call collision phenomenon occurs.

However, although the mobile terminal 100 stores the program, the external terminal may not store the program.

Hereinafter, the operation of the mobile terminal will be described with reference to FIG. 13 when only one of the two mobile terminals can implement the control method of the mobile terminal according to an embodiment of the present invention.

13 is a diagram for explaining a control method of a mobile terminal according to another embodiment of the present invention.

Hereinafter, the method of setting the call connection mode described with reference to FIG. 8 through FIG. 10 will be referred to as a DCD (Digit Comparision Dial) program.

Hereinafter, for convenience of explanation, A (100_1) will be used as a reference.

Referring to FIG. 13, A (100_1) stores a DCD program, and B (100_2) does not store the DCD program. In this situation, A (100_1) and B (100_2) can request a mutual call connection at substantially the same time.

In this case, both A (100_1) and B (100_2) can receive the DBM from the mobile communication network. However, the control method of the mobile terminal illustrated in FIGS. 4 and 8 can be applied to A (100_1), but B (100_2) can not be applied to the control method of the mobile terminal according to an embodiment of the present invention. Therefore, A (100_1) can set the call connection mode to the calling mode or the standby mode, but B (100_2) does not.

Therefore, A (100_1) needs to immediately respond to a call connection request from B (100_2), and a call connection to B (100_2) within a range that does not conflict with the call connection request of B (100_2) Request is preferred.

To this end, the mobile terminal 100 according to an exemplary embodiment of the present invention may control the call connection mode to selectively set a calling mode or a receiving mode for a predetermined period.

For example, referring to FIG. 13 (a), the mobile terminal 100 controls to operate in a calling mode for a time T1 based on a period T, and then controls the mobile terminal 100 to operate in a standby mode for a time T2 can do.

If the external terminal does not request a call connection during the origination mode (T1), the mobile terminal 100 may be connected to an external terminal with a call connection.

During the standby mode (T2), when the mobile terminal 100 does not request a call connection, the external terminal requests a call connection to the mobile terminal 100 and a call is connected between the mobile terminal and the external terminal have.

The T1 and T2 can be set by the user.

13B shows a case in which the operation time T3 in the calling mode is shorter than the operation time T4 in the standby mode.

13C shows a case where the operation time T5 to the calling mode is longer than the operation time T6 to the standby mode.

The operation time in the calling mode and the operation time in the standby mode can be set differently according to the calling tendency of the external terminal user.

For example, when the user of the communication target terminal is in a hurry, when the communication collision occurs, the call connection mode of the mobile terminal 100 tends to continuously request a re-call. In this case, the time T4 for operating in the standby mode can be set longer than the time T3 for operating in the calling mode as shown in FIG.

Thus, the possibility of the call connection between the two can be increased.

The above-described method of controlling a mobile terminal according to the present invention can be provided by being recorded in a computer-readable recording medium as a program for execution in a computer.

The control method of the mobile terminal according to the present invention can be executed through software. When executed in software, the constituent means of the present invention are code segments that perform the necessary tasks. The program or code segments may be stored in a processor readable medium or transmitted by a computer data signal coupled with a carrier wave in a transmission medium or a communication network.

A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored. Examples of the computer-readable recording device include a ROM, a RAM, a CD-ROM, a DVD 占 ROM, a DVD-RAM, a magnetic tape, a floppy disk, a hard disk, The computer-readable recording medium may also be distributed to networked computer devices so that computer readable code can be stored and executed in a distributed manner.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. The present invention is not limited to the drawings. In addition, the embodiments described in this document can be applied to not only the present invention, but also all or some of the embodiments may be selectively combined so that various modifications can be made.
