Description

Calling method of dual-band dual-mode terminal and dual-band dual-mode terminal for this purpose {METHOD FOR ORIGINATING CALL IN DUAL-BAND DUAL-MODE TERMINAL AND DUAL-BAND DUAL-MODE TERMINAL THEREFOR}

The present invention relates to a dual band dual mode terminal, and more particularly, to a call origination method of a dual band dual mode terminal in a fixed mobile convergence network (FMC) and a dual band dual mode terminal for the same.

Wired communication networks are developing into IP-based NGN (Next Generation Network) networks, and wireless communication networks are also developing into IP-based wideband code division multiple access (WCDMA) networks. Accordingly, wired and wireless communication networks, which have been developed so far, are being integrated on an IP basis, and this integration technology is called fixed mobile convergence (FMC). With the development of the wired / wireless integrated technology, a dual-mode terminal can be connected to a wired communication network to use IP-based Internet telephony (VoIP), and at the same time, to access a mobile communication network such as WCDMA and use ordinary mobile communication services. It is becoming.

In particular, wired / wireless integrated technology has become an issue in the corporate communications market. Conventionally, an extension call must be used for an extension terminal in an enterprise, and such an extension terminal has limitations in movement. However, when a wired / wireless integrated network is established in an enterprise, employees move using one dual-band dual-mode terminal. Within a workplace that can be connected to the back, you can make internal or external calls using an Internet phone, and within a workplace that cannot be connected to a wireless LAN, you can make free or personal calls between employees through a mobile communication network. As a result, the company's communication costs can be greatly reduced, and the company's work efficiency is further enhanced because it enables the user to make calls and send and receive e-mails while traveling.

However, the dual band dual mode terminal used in the wired / wireless integrated network in the enterprise has a problem in that it is vulnerable to privacy protection because it supports both Internet telephony service and general mobile communication service. In other words, when an internal call or a personal call is made using an internet phone through a wired / wireless integrated network in a company, personal privacy such as recording of the call record or the contents of the call may be unprotected. Therefore, when attempting to make a call in an enterprise using a dual band dual mode terminal, the user of the dual band dual mode terminal should decide whether to make a call using an Internet phone or a general mobile communication service.

To this end, the dual band dual mode terminal displays a pop-up window asking whether to make a call using an Internet phone or a general mobile communication service whenever a user inputs an incoming number and attempts to make a call. Alternatively, a special key may be assigned to the dual mode terminal so that the user can freely select it. However, both the method of displaying a pop-up window and the method of assigning a special key have a very troublesome problem because each time a called number is inputted.

The present invention has been proposed to improve the above problems, the call origination method of the dual-band dual-mode terminal for minimizing the user's operation in the wired / wireless integrated network environment and to selectively send the call to the Internet telephone network or mobile communication network and the same. The purpose is to provide a dual-band dual-mode terminal for.

In addition, according to another aspect of the present invention for achieving the above object includes a first communication means connected to the first communication network to provide a communication service, and a second communication means connected to the second communication network to provide a communication service. Call origination method in a dual-band dual-mode terminal, the step of receiving the incoming number; Selectively activating any one of the first communication means and the second communication means based on a comparison result of the digits of the called number and a threshold value; And sending a call to the called number through an activated communication means.

As described above, the present invention checks the number of digits of the incoming number input from the dual band dual mode terminal, and when the incoming number of digits less than the predetermined threshold is input, it is determined as a work telephone without user confirmation and attempts to connect to the Internet. When making a call from within the company by checking whether the user is a personal phone or a work phone only when a forwarding number of more than the threshold is entered, and optionally making an Internet phone call or attempting a mobile phone call according to the user's choice. It solves the hassle of checking how the user connects to the phone every time. In particular, when attempting an extension call having a predetermined number of digits below the threshold value, user convenience is improved because only extension number dialing is required as in a general extension terminal.

The foregoing and other objects, features and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings, in which: There will be. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a dual band dual mode terminal according to an embodiment of the present invention.

Referring to FIG. 1, the dual band dual mode terminal 100 according to the present embodiment includes an Internet telephony module 110, a mobile communication telephone module 120, a display unit 130, a handset 140, and a storage unit ( 150, an input unit 160, and a controller 170.

The Internet telephony module 110 communicates with a wireless LAN and the like through an antenna to perform a VoIP call through an Internet network. The Internet telephony module 110 may be implemented by mounting a H.323 or SIP (Session Initiation Protocol) protocol stack, and transmits and receives voice data packets when a call connection is made by the H.323 or SIP protocol stack. An example of a method in which the Internet telephony module 110 communicates with an access point (AP) such as an enterprise or a home may include a wireless personal area network (WPAN) technology such as WIFI or Bluetooth.

The mobile communication telephone module 120 communicates with a base station of a mobile communication network through an antenna to perform a circuit switched based call through the mobile communication network. The mobile communication network is a CDMA system, a WCDMA system, a GSM system, and the like. In the present invention, the mobile communication is a communication for performing a voice or video call while moving through a mobile communication network such as a CDMA system, a WCDMA system, or a GSM system.

The display unit 130 is a display device such as an LCD (Liquid Crystal Display) and displays a screen corresponding to a state of the dual band dual mode terminal 100 and a user's key input under the control of the controller 170.

The handset 140 performs a function of decoding a voice of a call counterpart through a speaker under the control of the controller 170, outputting the voice through a speaker, encoding a user's voice through a microphone, and transmitting the voice to a call counterpart. .

The storage unit 150 stores various data such as a message, a phone book, a picture, a video, and the like.

The input unit 160 receives a signal for operating the dual band dual mode terminal 100 from a user. The input unit 160 receives a signal from a user through a conventional keypad or a touch screen. The user signal input through the input unit 160 is transmitted to the controller 170.

The controller 170 controls the overall operation of the dual band dual mode terminal 100. Although not shown, the controller 170 includes a program memory in which a program for controlling the operation of the dual band dual mode terminal 100 is recorded, and a system memory in which data for executing the program is stored.

The controller 170 selects and activates any one of the Internet phone module 110 and the mobile communication phone module 120 according to a user's selection or a called number input by the user.

Preferably, when the user inputs the called number through the input unit 160 to make a phone call, the controller 170 analyzes the number of digits of the received called number, and when the number of digits of the called number is less than a predetermined threshold value. The Internet phone module 110 is immediately activated to attempt an internet phone call.

On the other hand, the controller 170 displays a selection menu (eg, a pop-up window) asking whether to make an Internet call or a mobile communication call on the display unit 130 when the number of the called number is greater than a predetermined threshold value. Accordingly, a user's selection input is received through the input unit 160.

In the present embodiment, since the dual band dual mode terminal 100 is used in a wired / wireless integrated network of an enterprise, the control unit 170 is a personal as shown in FIG. 4 when the number of digits of the called number input by the user is greater than or equal to a predetermined threshold. A selection menu (eg, a pop-up window) asking whether the telephone is a 'call' or a 'work phone', and receives a user's selection input through the input unit 160 accordingly. The threshold is preferably '7'. Since the minimum number of digits of the mobile communication number is '10' and the minimum number of digits of the landline number is '7', if the number of the called number is less than '7', the extension is an extension number. If '7' or more, it can be regarded as a phone number other than the extension number, so it is necessary to perform the above verification procedure.

In another embodiment, the control unit 170 determines whether it is a 'personal phone' or a 'work phone' as shown in FIG. 4 only when the called number input by the user starts with '0' and has seven or more digits. A selection menu may be displayed and a user's selection input may be received accordingly. Since the extension number generally does not start with '0', the confirmation procedure as described above can be performed only when the called number starts with '0' and has more than '7' digits.

On the other hand, when the called number is less than the threshold there is a case that the call must be made through the mobile communication network. For example, in the case of a call forwarding service that allows an incoming call to be received at a specified number, a call is input by entering a called number of less than 7 digits starting with a special number (for example, ** 71) to apply for call forwarding service. For example, outgoing calls for such forwarding services should be sent to the mobile communication network. As another example, in case of an emergency call, such as '112', '119' it is necessary to make a call to the mobile communication network.

Therefore, when the number of digits of the called number input by the user is less than a predetermined threshold, the controller 170 of the dual band dual mode terminal 100 checks whether the called number starts with a special number or is an emergency call number. When starting with a special number or an emergency call, as shown in FIG. 4, a selection menu may be displayed asking whether the user is a 'personal phone' or a 'company phone', and a user's selection input may be received accordingly. In this case, the call may be transmitted to the mobile communication network by immediately activating the mobile communication phone module 120 without receiving confirmation from the user.

The controller 170 receiving the called number and the call connection input analyzes the number of digits of the received called number and checks whether the number of digits of the called number is greater than or equal to a predetermined threshold value (S205). Here, the threshold value is preferably '7' as described with reference to FIG. 1, or it may be checked whether the called number starts with '0' and is '7' or more. However, the present invention is not necessarily limited thereto, and the judgment condition may be changed according to the exemplary embodiment.

If the number of the called number is less than the threshold value, the controller 170 of the dual band dual mode terminal 100 activates the Internet telephony module 110 and attempts to connect to the called number by accessing the wireless LAN or the like (S215). ).

However, when the number of digits of the called number is greater than or equal to the threshold value, the controller 170 of the dual band dual mode terminal 100 outputs a popup window for the call type to the display 130 (S207). As shown in FIG. 4, the display unit 130 outputs a pop-up window asking whether it is a personal phone or a work phone.

The controller 170 of the dual band dual mode terminal 100 receives a user input for the call type inquiry through the input unit 160 (S209). The user's input may be received via a key button or may be received via a touchpad. The method of receiving a user input may be variously modified and is not limited to the present embodiment.

The controller 170 of the dual band dual mode terminal 100 receiving the user's input for the call type selection checks whether the user's input is a 'work phone' or a 'personal phone' (S211). In the case of input of 'personal phone' instead of 'telephone', the mobile communication module 120 is activated to access the base station of the mobile communication network and attempt to connect the call to the called number (S213).

On the other hand, when the user's input is a 'work phone', the controller 170 of the dual band dual mode terminal 100 activates the Internet telephony module 110 and accesses a wireless LAN or the like to connect a call to the called number. It tries (S215). The called number may be an extension number or may be a number for attempting to call a mobile communication terminal inside or outside a company through a wired / wireless integrated network in a company.

As described with reference to FIG. 2, in a wired / wireless integrated network environment in an enterprise, the dual band dual mode terminal 100 transmits a call to the user via an Internet phone only when the number of the called number is greater than or equal to a predetermined threshold, or moves. It checks whether or not to make a call to the communication network, and automatically sends a call to the Internet telephone when the number of the called number is less than the threshold. Accordingly, the user can solve the hassle of selecting a network to connect to whenever a called number is input.

Here, the threshold value is preferably '7' as described with reference to FIG. 1, or it may be checked whether the called number starts with '0' and is '7' or more. However, the present invention is not necessarily limited thereto, and the judgment condition may be changed according to the exemplary embodiment.

When the number of digits of the called number is less than the threshold value, the controller 170 of the dual band dual mode terminal 100 checks whether the called number includes a special number or whether the called number is an emergency call (S307). ). An example of the special number may include '** 71' for call forwarding service, and examples of the emergency call are numbers such as' 112 'and 119'.

The control unit 170 of the dual band dual mode terminal 100 includes a special number in the called number, or when the called number is an emergency call, activates the mobile communication module 120 and accesses the base station of the mobile communication network. Attempts to connect the call to the called number (S317).

On the other hand, the control unit 170 of the dual-band dual-mode terminal 100, if the incoming number does not contain a special number, and the incoming number is not an emergency call, by activating the Internet telephony module 110 to wireless LAN The call is attempted to connect to the called number by accessing the terminal and the like (S317). That is, the dual band dual mode terminal 100 attempts an extension call or an external call through the Internet in the company.

On the other hand, as a result of checking in step S305, if the number of digits of the called number is greater than the threshold value, the controller 170 of the dual band dual mode terminal 100 outputs a pop-up window for the call type to the display unit 130 (S309). As shown in FIG. 4, the display unit 130 outputs a pop-up window asking whether it is a personal phone or a work phone.

The control unit 170 of the dual band dual mode terminal 100 receives a user input for the call type inquiry through the input unit 160 (S311). The user's input may be received via a key button or may be received via a touchpad. The method of receiving a user input may be variously modified and is not limited to the present embodiment.

The controller 170 of the dual band dual mode terminal 100 receiving the user's input for the call type selection checks whether the user's input is a 'work phone' or a 'personal phone' (S313). In the case of input of 'personal phone' instead of 'telephone', the mobile communication module 120 is activated to access the base station of the mobile communication network and attempt to connect the call to the called number (S317).

On the other hand, when the user's input is a 'work phone', the controller 170 of the dual band dual mode terminal 100 activates the Internet telephony module 110 and accesses a wireless LAN or the like to connect a call to the called number. Attempt is made (S315). That is, the dual band dual mode terminal 100 attempts an extension call or an external call through the Internet in the company.

As described with reference to FIG. 3, in a wired / wireless integrated network environment in an enterprise, the dual band dual mode terminal 100 transmits or receives a call to an Internet telephone to a user only when the number of the called number is greater than or equal to a predetermined threshold. It checks whether or not to make a call to the communication network, and automatically sends a call to the Internet telephone when the number of the called number is less than the threshold. At this time, even when the number of the called number is less than the threshold value, if the called number includes a special number or in case of an emergency call, the call is attempted through the mobile communication network without attempting to make a call.
