BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and system for providing a message service when a call service is performed between a calling terminal and a called terminal performing a call service through a communication network, And more particularly, to a method and system for providing a message service through a data network separate from a communication network, in parallel with a call service, or in a manner of terminating a call service and switching to a message service.

The present invention also relates to a communication terminal for providing a message service when performing a call service using such a system.

With the rapid spread of smart phones and broadband communication services such as LTE services being widely spread, a variety of services are being provided using smart phones. In recent years, various types of message services using smart phones have been increasing.

Meanwhile, if the calling terminal requests a call connection but the called terminal does not answer the call service, the calling terminal user leaves a voice message in a separate voice mailbox or uses a separate SMS or other messaging application to transmit the message All of which are provided separately from the call service. Therefore, there is a limitation that the message service can not be provided together with the interface provided through the call service. That is, the communication service provided by the communication terminal can receive only the call service by the operating system that is basically installed in the communication terminal, and there is no way to receive the message service while performing the call service.

Korean Patent Laid-Open Publication No. 10-2007-0054077 (published on May 28, 2007) discloses a method and apparatus for transmitting a message during a call. According to this method, a DTMF signal is received from a terminal during a call, and a voice, a text message or the like previously registered in the other terminal according to the detection of the DTMF signal can be transmitted during the call. However, such a method is performed through resources such as exchanges that are coupled to a communication network and a communication network during a call, and thus, there is a limitation in that the method is basically performed via a call network.

On the other hand, applications that provide messaging services by popularization of smart phones have been widely used. Although this messaging service application can be performed simultaneously with the call service, there is a limit in that a separate operation is required for switching the screen to the application, in addition to the interface for providing the call service, the user must execute the corresponding application.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a connection state between a calling terminal and a called terminal, and a message service providing system for providing a message service when a calling service is performed between a calling terminal and a called terminal performing a call service through a communication network.

Referring to FIG. 1, a message service providing system (hereinafter simply referred to as a message service providing system 100) for providing a message service when a call service is performed between a calling terminal and a called terminal performing a call service through a communication network, Is connected between the calling terminal 200 and the called terminal 300 via the network.

The calling terminal 200 and the called terminal 300 are connected through a communication network and perform a call service through the communication network.

Here, the communication network of FIG. 1 refers to a conventional network that performs communication services by any one of a public switched telephone network (PSTN), a mobile communication network, and the Internet network or a combination thereof, and the actual communication network includes a communication network such as an exchange and HLR Resources. Through the communication network, the calling terminal 200 and the called terminal 300 are provided with a call service as is known from the related art.

1, the term " network " includes a well-known wired / wireless Internet, a mobile communication network, or a combination thereof. In the present invention, only a data transmission / Data packet network.

The calling terminal and the called terminals 200 and 300 are known publicly known means for receiving a call service through a communication network and refer to a mobile communication terminal or a wired communication terminal, 200,300) is preferably a so-called "smart phone" which can be installed and executed by an application (application) and has an internet connection means. As is well known, the calling terminal and the receiving terminal 200, 300 may include a display unit (not shown) performing a touch screen input and output function. In addition, the source and destination terminals 200 and 300 include an operating system (OS) for managing the overall operation of the terminal.

The calling terminal and the receiving terminals 200 and 300 have the following features in the present invention.

The calling terminal 200 and the called terminal 300 can receive a message service through the message service system 100 in parallel with the call service before or during a call connection while performing a call service through a communication network, So that the message service is provided through the message service system 100.

2 is a block diagram illustrating an internal configuration of a message service providing system 100 according to an embodiment of the present invention.

Referring to FIG. 2, the message service providing system 100 includes a data path managing unit 110 and a message service providing unit 120.

The data path management unit 110 performs a function of forming a data path between the calling terminal 200 and the called terminal 300. That is, after receiving the first path connection request signal from the calling terminal 200 and receiving the second path connection request signal from the called terminal 300, Thereby forming a data path between the terminal 200 and the destination terminal 300. The formed data path functions as a path through which the message data is transmitted as will be described later.

Here, the first path connection request signal is transmitted from the calling terminal 200 to the message service providing system 100 when a call service event occurs in the calling terminal 200. The call service event is a call connection request event which is a state of requesting a call connection to the destination terminal 300 in case of a call terminal 200 requesting a call connection, And a call termination event when the call is terminated with the call termination terminal 300. The call service event may be detected by an event detection unit included in an operating system (OS) installed in the calling terminal 200.

The second route connection request signal is transmitted from the destination terminal 300 to the message service providing system 100 when a call service event occurs in the destination terminal 300. [ The call service event in the destination terminal 300 includes a call response request event in which a call connection request is received from the call terminal 200, a call connection event in a call connection state with the call terminal 200, And a call termination event in which the call termination with the terminal 200 is terminated.

For example, when the calling terminal 200 requests a call connection to the called terminal 300, the calling terminal 200 generates a call connection request event, and then transmits a first path connection request signal to the message service providing system 100 . The calling terminal 300 receiving the call connection request from the calling terminal 200 generates a call response request event and accordingly transmits a second route connection request signal to the message service providing system 100.

The data path management unit 110 receives the first and second path connection request signals from the calling terminal 200 and the called terminal 300 and receives the first and second path connection request signals from the calling terminal 200 and the called terminal 300, A data path is formed so that message data can be transmitted and received as will be described later.

The message service provider 120 performs a function of providing a message service by transmitting message data between the calling terminal 200 and the called terminal 300 through the data path as described above. The data path management unit 110 may be configured to transmit data from the terminal of at least one of the calling terminal 200 and the called terminal 300 in a state in which a data path is formed between the calling terminal 200 and the called terminal 300, The message service providing unit 120 of the message service providing system 100 receives the message service change request signal for requesting the switching to the message service and transmits the message service change request signal to the message service providing system 100, And receives a message service conversion acceptance signal accepting a transition from the counterpart terminal to the message service, the message service is provided by transmitting and receiving message data between the calling terminal 200 and the called terminal 300 through the formed data path .

3 is a diagram illustrating an exemplary configuration of a message service providing apparatus 400 for providing a message service included in a calling terminal 200 and a called terminal 300 connected to a message service system 100. [

The message service providing apparatus 400 shown in FIG. 3 is included in the calling terminal 200 and the called terminal 300 and is included as part of the operating system (OS) of the calling terminal 200 and the called terminal 300, May be installed and included in the form of an application. Also, it may be implemented in hardware within the calling terminal 200 and the called terminal 300.

3, the message service providing apparatus 400 is commonly provided to the calling terminal 200 and the called terminal 300. Hereinafter, the calling terminal 200 and the called terminal are collectively referred to as communication terminals 200 and 300. [ In FIG. 3, only the message service providing apparatus 400 is shown as a configuration of the communication terminals 200 and 300 according to the present invention, and other general configurations of the communication terminals 200 and 300 are omitted.

The data path management unit 410 is a means for forming a data path with the message service providing system 100. When the communication service event is detected in the communication terminals 200 and 300, And transmits the path connection request signal to the mobile station. For example, when the communication terminal is the calling terminal 200 as a call service event, when the calling terminal 200 receives a call connection request event requesting a call connection from the calling terminal 300 to the calling terminal 200, (Not shown), and the data path management unit 410 accordingly transmits a path connection request signal (first path connection request signal) to the message service providing system 100. At this time, the message service providing system 100 receives another route connection request signal (second route connection request signal) from the counterpart terminal of the call service, that is, the destination terminal 300 that receives the call connection request signal, The service providing system 100 forms a data path between both communication terminals.

The message service switching management unit 420 performs a function for processing a request for switching to a message service by a user while performing a call service. That is, the message service switching management unit 420 causes the message service switching request selecting unit (not shown) to be displayed on the display unit (not shown) of the communication terminals 200 and 300 and the user selects the message service switching request selecting unit The message service providing system 100 transmits a message service change request signal to the message service providing system 100 to notify that the user has requested to switch to the message service. Thereafter, upon receiving a message service switching signal from the message service providing system 100, the message service performing unit 430 performs a message service function.

Here, when the message service change request signal is transmitted to the message service providing system 100, the message service providing system 100 transmits the message service change request signal to the counterpart terminal, The message service switching control unit 420 transmits a message service switching signal indicating that the counterpart terminal has accepted the switching to the message service.

When the message service switching signal is received from the message service providing system 100 as described above in the message service switching management unit 420, the message service performing unit 430 transmits the message service switching signal to the message service providing system 100, And performs a message service by transmitting the message data to the terminal and receiving the message data from the counterpart terminal. That is, when the message service switching unit 430 receives the message service switching signal, the message service performing unit 430 displays a message service interface (not shown) for providing a message service through the display unit and displays the message data inputted through the message service interface as a data path To the message service system 100 and receives the message data (transmitted by the counterpart terminal) from the message service system 100 and displays the message data through the message service interface, thereby providing a message service.

Here, the call service may be performed in parallel with the message service. That is, since the call service is performed through the call network as described in FIG. 1 and the message service is performed through the network, which is a data packet network, the call service and the message service can be simultaneously performed. To this end, the communication terminals 200 and 300 according to the present invention partially provide a message service switching request selection unit on an interface representing a call service event, so that a call service event can be performed and a user's selection can be inputted.

Meanwhile, the call service may be terminated and the message service may be performed. That is, after receiving the message service switching signal from the message service switching management unit 420, a call termination selection unit (not shown) for allowing the display unit of the communication terminal 200 or 300 to select whether or not to terminate the call service When the user of the communication terminal 200 or 300 selects the communication service event, the message service service unit 430 can terminate the corresponding call service event and allow the message service to be performed.

FIG. 4 is a flowchart illustrating a method of providing a message service through the communication terminals 200 and 300 and the message service providing system 100 described with reference to FIGS. 1 to 3. In the embodiment of FIG. 4, A call connection request event for requesting a call connection from the calling terminal 200 to the called terminal 300 occurs.

Referring to FIG. 4, when a call connection request signal is generated from a calling terminal 200 to a called terminal 300, an event detection unit (not shown) of the calling terminal 200 generates a call connection request event (S100), and the call connection request signal is transmitted to the called terminal 300 through a resource such as an exchange of a communication network (S110).

When a call connection request event occurs in the calling terminal 200, the message path management unit 410 transmits a first path connection request signal to the message service providing system 100 (S120). At this time, although not shown in the figure, the calling terminal 200 can transmit a call service status signal indicating that a call connection request event has occurred to the message service providing system 100. The message service providing system 100 can confirm the call status of the calling terminal 200 based on the call service status signal and can manage the call status upon switching to the message service.

Upon receiving the call connection request signal, the call terminal 300 generates a call response request event, for example, by ringing a telephone bell (S130). Accordingly, the message path management unit 410 of the destination terminal 300 2 path connection request signal to the message service providing system 100 (S140).

Upon receiving the first and second path connection signals, the message service providing system 100 forms a data path for transmitting and receiving data, that is, message data to be described later, between both terminals through a network (S150). As described above, the network herein means a data packet network separate from the communication network.

Thereafter, the message service switching management unit 420 of the calling terminal 200 and the called terminal 300 displays the message service switching request selection unit through the display unit of each terminal (S160, S170). The message service switching request selection unit generates a message service switching request signal by selecting the message service switching request when the user wishes to switch to the message service while performing the communication service, and transmits the message service switching request signal to the message service system 100.

FIG. 5 shows an example of a status screen displayed on the display unit of the destination terminal 300 by the message service switching request selection unit.

Referring to FIG. 5, in the display unit of the call receiving terminal 300, a "call transfer" selection button is displayed in the middle of the screen along with an interface for notifying that the call has come. If the user selects this mode by touching or performing such a function as the message service switching request selecting unit, the message switching service request signal is generated in the called terminal 300 and the message service switching system 100 selects the ' .

Meanwhile, the message service changeover request signal may be generated and transmitted when there is no response input from the user within a predetermined time in the call connection request event or the call response event, in the terminal transmitting the message service changeover request signal. For example, if the user of the terminating terminal 300 does not respond to the call response request event within 3 seconds by setting 3 seconds in advance, it may automatically generate the message service change request signal.

When the user of the destination terminal 300 selects the "call transfer" selection button as shown in FIG. 5 or if there is no response within the preset time, the message service switching management unit 420 of the destination terminal 300 transmits the message The message service providing system 100 transmits a message service switching request signal to the message service providing system 100 to notify the calling service terminal 100 of the request to switch the service to the calling terminal 200 300) transmits a message service switching request signal indicating that the user requests switching to the message service (S200).

Here, the message service change request signal may include identification information of the counterpart terminal. That is, the message service change request signal transmitted from the called terminal 300 may include identification information of the calling terminal 200, such as telephone number and ID. The message service providing system 100 can identify and identify a data path formed between the terminals and the terminals on which the message service is to be performed based on the identification information.

Upon receiving the message service change request signal, the calling terminal 200 provides an interface for displaying the message service change request signal through the display unit and allowing the user to select whether or not to accept the switch to the message service. Upon selection (acceptance) (S210), a message service conversion acceptance signal is transmitted to the message service providing system 100 (S220).

6 is a screen showing a state in which an interface for selecting whether or not to accept switching to the message service is provided on the display unit of the calling terminal 200 is provided. 6, when the user selects "Accept ", the message service switching management unit 420 of the calling terminal 200 transmits a message service conversion acceptance signal to the message service providing system 100. [

When the message service providing system 100 receives the message service switching acceptance signal from the calling terminal 200, the message service switching system 100 transmits a message service switching signal to the calling terminal 200 and the called terminal 300, The calling terminal 200 and the called terminal 300 provide the message service interface through the display unit by the message service performing unit 430 in steps S250 and S260.

When the message data is input through the message service interface, the input message data is transmitted to the counterpart terminal through the formed data path and message service system 100, and the message data input from the counterpart terminal is similarly transmitted to the data path and message service system (100), and displays the message on the message service interface (S270).

7 shows an example of a screen for performing a message service by the message service performing unit 430 of the calling terminal 200 and the called terminal 300. [

As described above, the message service performing unit 430 of each terminal displays a message service interface for providing a message service on the display unit, which can be provided as shown in FIG.

As shown in FIG. 7, a message indicating that the message service has been switched is output and a message service interface is provided, through which message data can be input and message data transmitted from the counterpart terminal can be displayed.

Meanwhile, in step S270, transmission and reception of message data may be performed in the following manner.

In other words. The message service providing system 100 stores message data transmitted from each of the terminals 200 and 300 in a message queue. At this time, the message ID information for message identification and the identification information of the terminal that transmitted the message data can be stored together. Meanwhile, when message data is stored in the message queue, the message service providing system 100 transmits a message queue event indicating that the message to be received by the terminal to receive the stored message data is stored in the queue. At this time, the message queue event includes the token ID information for receiving the message data.

Upon receiving the message queue event, the terminal transmits a message data transmission request signal to the message service providing system 100. At the same time, the message service providing system 100 transmits the message data transmission request signal to the message service providing system 100, And transmits the message data to the terminal that has transmitted the message data transmission request signal.

Meanwhile, FIG. 8 shows a screen when a message service is to be terminated by one of the terminals 200 and 300 while performing a message service.

Fig. 8 shows a state where a selection button for confirming that the message service is to be terminated is provided through the display unit when the "x" button displayed on the upper right of the screen of Fig. 7 is selected. . Select "No" to return to the status of the message service interface again.

Meanwhile, although not explicitly shown in the embodiments of FIGS. 4 to 8, the process of switching to the message service and the message service provision process may be performed in parallel with the call service or after the call service is terminated.

For example, in FIG. 4, a call connection state, that is, a call service event may be terminated by providing a selection button for terminating the call connection state in any of steps S190 to S20.

In FIG. 6, when a message service change request signal transmitted from the destination terminal 300 is displayed on the display unit of the calling terminal 200, it is automatically notified that the call connection request event ends. If the message service switching is accepted as described above (S210), the call connection request event is automatically terminated and the message service is switched to perform only the message service.

Meanwhile, as described above, the call service is performed through the call network, and the message service is performed through the network, which is a data packet network.

FIG. 9 is a screen for explaining another example in which a message service change request signal is generated in step S180 of FIG.

Next, a method of actually implementing the communication terminals 200 and 300 including the message service providing apparatus 400 according to the present invention will be described with reference to FIGS. 11 and 12. FIG.

The message service providing apparatus 400 included in the communication terminals 200 and 300 shown in FIG. 3 for carrying out the present invention may be integrated into an operating system included in the communication terminals 200 and 300. Alternatively, it may be installed and implemented in the form of an application program (application) in the communication terminal 200 or 300 afterwards. In particular, operating systems such as, for example, androids are particularly well suited to the present invention, since terminal manufacturers or application manufacturers are open to receiving call service events from an operating system (OS) and performing various processes. For example, when a call connection request event occurs in the Android operating system, the event detection unit of the operating system of the communication terminal 200 or 300 detects the call connection request event, and then operates the message service providing apparatus 400 implemented in the form of an application program have.

FIG. 11 is a diagram for explaining an example in which the configuration of the message service providing apparatus 400 included in the communication terminals 200 and 300 for implementing the present invention is implemented by an application program (application).

11, the communication terminals 200 and 300 include an event transmission unit 51 and an application program management unit 52 in an operating system (OS). The configuration of FIG. 11 exemplifies the actual configuration of the Android operating system, and the terms may be different in other operating systems, but the basic principle is similar.

The event transmitting unit 51 receives various events generated from the hardware or application programs (applications) of the communication terminals 200 and 300, confirms the application program to which the received event is to be transmitted in the application program management unit 52, And notifies that an event has occurred, thereby executing a function of the application program.

The application program management unit 52 stores in advance a list of application programs to receive the event according to the type of the event. The list of such application programs is registered in the application program management unit 52 when the application programs are installed.

12 is a diagram showing an example of the internal configuration of the application program management unit 52. As shown in Fig.

Referring to FIG. 12, the application program management unit 52 includes an event type 521 and a list 522 of application programs to receive the event. In Fig. 12, "call connection request" and "call termination" events are exemplarily shown as types of events. The "call connection request" event can be triggered by an event such as entering a phone number on the keypad, selecting a contact from the address book, requesting a call from the application, and the like. The detection unit (not shown) detects this and notifies the event transmission unit 51. The event transmission unit 51 transmits a list of application programs set for the event to an application program list 522 as shown in FIG. 12 Check and run the checked application.

In the application list registered for the "call connection request" event in FIG. 12, two kinds of application programs # 1 and # 2 are registered. The application program management unit 52 notifies the event transmission unit 51 that the application program # 1 and the application program # 2 are registered for the "call connection request" event and the event transmission unit 51 notifies the application program # Program # 2 sends a signal indicating that a "call connection request" event has occurred.

Here, when transmitting an event to the application programs # 1 and # 2, the event transmission unit 51 may simultaneously notify the event to all of the application programs in the application program list, notify only one of them of the priority event, It is possible to use a method of notifying an event to the next application when the execution of the application is completed or the execution is stopped. This is possible by setting how to notify the event in the application program management unit 52.

For example, in the case of the "call connection request" event, it is possible to notify the event to the application program # 1 first, and notify the application program # 2 when the execution of the application program # 1 ends. In this case, when the confirmation request signal is received from the event transmission unit 51, the application program management unit 52 first informs the information of the application program # 1. When the event transmission unit 51 receives the information of the application program # 1 as an acknowledgment signal for the event from the application program management unit 52, the event transmission unit 51 transmits the event to the application program # 1. And then loaded into the operating system and executed.

On the other hand, in the case of the "call connection request" event, it is possible to simultaneously notify the application program # 1 and the application program # 2 of the event. In this case, when the confirmation request signal is received from the event transmission unit 51, the application program management unit 52 informs all of the application programs # 1 and # 2. The event transmitting unit 51 receives the information of the application programs # 1 and # 2, notifies the application programs # 1 and # 2 that an event has occurred at the same time, and the application programs # 1 and # 2 are executed together in parallel.

1 to 10 can be implemented on the basis of the principles described with reference to FIGS. 11 to 12. The data path management unit 410, the message service switching management unit 420, and the message The message service providing apparatus 400 including the service performing unit 430 may be implemented as one application program.

For example, when a call connection request event occurs, a general application program in the communication terminal 200 or 300 is called a call manager. In general, when a call connection request event occurs, And the application program # 1 in the application program list as shown in FIG. 12 to execute the call connection process.

The message service providing apparatus 400 having the data path managing unit 410, the message service switching managing unit 420 and the message service performing unit 430 is implemented as an application program and installed in the communication terminals 200 and 300, In the application program list 522 of the application program # 2. In addition, set the execution order of the applications in the application list to be executed at the same time as described above.

That is, in the case of the "call connection request" event, if an application program for implementing the message service providing apparatus 400 according to the present invention is registered as the application program # 2 and is set to be executed simultaneously with the application program # 1, Application programs # 1 and # 2 can be run simultaneously if they occur.

In this case, when a call request signal (call connection request event) occurs as one of the events, the event transmission unit 51 transmits the information of the application program set for the event that the call request signal is detected to the application program management unit 52 And the application program management unit 52 simultaneously transmits the information of the application program # 1 (existing call manager) registered for the event and the information of the application program # 2 in which the message service providing apparatus 400 according to the present invention is implemented, And the event transmitting unit 51 simultaneously executes the application program # 1 (call manager) and the application program # 1 (the message service providing apparatus 400 according to the present invention). Accordingly, an application program including the configurations of the international call determination unit 120, the international call rate information providing unit 130, and the international call provider identification number determination unit 140 as described with reference to FIG. 1 to FIG. 1, the message service provision apparatus 400 according to the present invention is executed while performing communication service in the communication terminals 200 and 300 as described in FIGS. 1 to 6, 200,300). ≪ / RTI >

In this state, when the call service is terminated and only the message service is desired to be performed, only the application program # 1 is terminated so that only the message service can be performed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the invention as defined by the appended claims. Points should be noted.
