Meanwhile, smartphones (113) such as iPhones and Android phones have been rapidly spreading, which has raised the problem of telecommunication costs. Due to the convenience of use due to the functions of the address book and the management of the call log, the smartphone is used more at home than in a general analog phone, and accordingly, a plan having a basic frequency sufficient enough to cover such usage is selected. Which has been accelerating the rise.

Thus, as shown in FIG. 1, there are a number of applications that make it possible to make a call with a smartphone more inexpensively. However, these applications require additional account management, including charge for usage charges, which increases management burdens. Accordingly, people who have a lot of smartphone calls are reluctant to use the device. While the use of mobile communication network by smart phone is very active, the utilization of home communication infrastructure constructed through the investment of facilities for new construction or remodeling is very poor.

Accordingly, there is a need for a technique for integrally managing various communication technologies and terminal devices in the home centering on VoIP as the cheapest communication means. Accordingly, the user can conveniently use the smartphone at home, reduce the usage amount of the mobile communication network related to the actual smartphone, lower the communication cost of the smart phone by utilizing the home communication infrastructure, and increase the investment efficiency of the home communication infrastructure. A technique capable of solving the problems of the prior art is desired.

For this, the residential gateway 200 according to the present invention includes an FXS module 210, a deck module 220, a wireless LAN module 230, and a VoIP control module 240.

The FXS module 210 may be configured to provide a general analog telephone connection as a module for interfacing the analog phone 111 or may be configured to provide an Internet telephone function to the analog phone 111 via the VoIP adapter function. The present invention is not limited in this regard.

The DECT module 220 is a module for interfacing one or more DECT handset 112 to allow the residential gateway 200 to function as a host station according to the DECT standard to implement digital cordless telephone functionality. As mentioned above, Dext is a digital cordless telephone that uses the frequency band of 1.88 GHz to 1.90 GHz, and connects up to six handsets to one main body. Since the decode is an internationally standardized technology standard, the residential gateway 200 and the deck handset 112 are operable in principle even though they are composed of different product models.

The wireless LAN module 230 is a module for attaching one or more smartphones 113 to the residential gateway 200 so that the residential gateway 200 can access the access point 100 according to the IEEE 802.11 standard or the WiFi standard.

As described above, the wireless LAN provides high-speed wireless data communication through the 2.4 GHz and 5.8 GHz frequency bands.

The VoIP control module 240 establishes a VoIP solution in the residential gateway 200 and through the integrated operation of the deck handset 112 and the smartphone 113 connected to the residential gateway 200, . At this time, a plurality of terminal apparatuses (a deck handset, a smart phone) can perform an external and internet telephone call through a single domestic telephone number through the line number translation function provided by the LNT manager 243. [ The VoIP control module 240 for performing such a function includes a Dex manager 241, a Phone APP manager 242, an LNT manager 243, a call manager 244, a VoIP processor 245, and a database 246 .

The DECT manager 241 is a module for implementing a digital cordless telephone function in one or more deck handsets 112 through an Internet telephone path provided by the VoIP processing unit 245 by performing a role of a host station according to the DECT standard . Since the standard is a well-known technology, a detailed description is omitted here.

The phone application manager 242 operates in cooperation with the phone APP installed in the smart phone 113 and thereby implements an Internet telephone service in one or more smartphones 113 through the Internet telephone path provided by the VoIP processing unit 245 . The smartphone 13 used by the family members is attached to the wireless LAN through the phone APP manager 242 and the wireless LAN module 230 and incorporated into the VoIP service of the residential gateway 200. [

The LNT manager 243 may include at least one smartphone 113 or 114 used by a family member for the home telephone number assigned to the residential gateway 200 and used by the deck handset 112 or the analog phone 111 So as to enable the integrated operation according to the present invention. The home telephone number can be used by the internet telephone capable terminal, the direct handset 112 and the analog phone 111 which are basically connected to the residential gateway 200. In this specification, the descriptive handset 112, .

3, an IP telephone number 070-7777-1111 is assigned to the residential phone number from the VoIP call server 300 in the residential gateway 200, so that the deck handset 112 is connected to the DECT module The home phone number 070-7777-1111 is used through the home phone 220 and the DDK manager 241. [

The family members use two smartphones 113 and 114, respectively, and they are assigned a mobile communication telephone number 010-1234-5555 and 010-4321-6666, which are used in connection with the external communication system . The smart phone 113 and the smartphone 114 are connected to the VoIP control module 240 by the operation of the call manager 244 when they are attached to the residential gateway 200 through the wireless LAN module 230 and the phone APP manager 242. [ The VoIP solution provides Internet telephony. At this time, the LNT manager 243 allows the smart phones 113 and 114 to share the local telephone number 070-7777-1111, and the operation of the LNT manager 243 for this purpose is referred to as line number translation . The LNT manager 243 utilizes a sub-number in order to internally identify a terminal device sharing the same line number.

The call manager 244 performs call connection management so that the deck handset 112 and the smart phones 113 and 114 can perform internet telephone calls using the VoIP solution installed in the residential gateway 200. [ In addition, the call manager 244 performs the operation of integrating the internet telephone routes such as the call call, the call pickup, and the call transfer with the help of the line number translation of the LNT manager 243, Will be described later in detail with reference to Figs. 4 to 11.

The VoIP processing unit 245 is a module for providing various processing operations to the residential gateway 200 according to the VoIP solution. In general, H.323 and SIP (Session Initiation Protocol, Session Establishment Protocol) are used as a technical specification for performing Internet telephone connection through VoIP. In the present specification, description of the invention will be made based on SIP standard. The SIP specification specifies procedures for communication terminal devices on the Internet to identify each other and to create, delete, and modify multimedia communication sessions with each other. Since Internet telephone standards such as SIP and H.323 correspond to known technologies, detailed description is omitted here.

The database 246 is a module for storing various kinds of information for the VoIP control module 240 to operate. Particularly, the LNT manager 243 stores identification information of the smart phones 113 and 114 Provides storage space for storing combinations of server numbers. The database 246 may be implemented in the form of a flash memory, a hard disk, a web disk, a cloud disk, or the like.

4 and 5 are conceptual views illustrating a process of registering the smartphone 113 in the database 246 so that the LNT manager 243 can perform line number translation in the present invention.

Step S110: First, the device APP installed in the smartphone 113 requests device registration in order to participate in the integrated VoIP service provided by the residential gateway 200. Since the dedicated phone APP for the present invention is installed in the smartphone 113, a device registration request of step S110 is made by the user operating the device registration menu provided by the phone APP.

Step S 120: The LNT manager 243 of the residential gateway 200 determines whether the device is registered by confirming security authentication of the smartphone 113. Since wireless LANs can reach a considerable distance, it is desirable to provide security authentication technology to prevent other home smartphones from connecting. Various methods for confirming the security authentication with respect to the smart phone 113 can be implemented. A general public key encryption technique may be used or an identification number of a smartphone to be registered may be inputted in advance on the setting menu screen of the residential gateway 200 or a password may be set in the residential gateway 200. [ In addition, a smart tag (e.g., an NFC tag) may be attached to the residential gateway 200 in advance so that the smart phone 113 can automatically process security authentication when the smart tag is tagged.

An example of a security authentication process suitable for application to the registration process of the smartphone 113 is shown in FIG. The phone number (010-1234-5555) of the smartphone 113 can be registered in the residential gateway 200 through the procedure of [FIG. 12].

Step S130: When the smartphone 113 passes the security authentication, the LNT manager 243 transmits a sub-number (e.g., 01) for the local telephone number (e.g., 070-7777-1111) of the residential gateway 200 ) And assigns it to the corresponding smart phone 113. The subnumber is for internally identifying a plurality of terminal apparatuses integrally operated by the residential gateway 200, and is assigned by the LNT manager 243 so that they do not collide with each other.

Steps S140 and S150: The LNT manager 243 combines the identification information of the smartphone 113 and the assigned sub-number in the database 246 and registers the registration result (e.g., registration OK, sub-number) To the smartphone 113 so as to recognize that the phone APP is normally registered.

In the above description, the smart phone 113 voluntarily requests the device to register with the gateway 200 through the menu operation of the user. However, the present invention can be implemented in other ways. For example, when recognizing the wireless LAN connection of the smartphone 113 through the wireless LAN module 230, the residential gateway 200 invites the smartphone 113 to register the device through the phone APP manager 242 and the smartphone 113 may request the device registration in response to the solicitation.

6 and 7 are conceptual diagrams illustrating a call invocation process in which the smart phone 113 makes an external call to the Internet phone using the line number translation provided by the LNT manager 243 in the present invention.

Step S210: The user first operates the telephone dial button (telephone dialing menu) provided in the phone APP installed in the smart phone 113 to transmit a call request for the specific party to the call manager 244.

Step S220: If a call invocation request is provided from the phone APP, the call manager 244 inquires the database 246 via the LNT manager 243 so that the smartphone 113 can access the [Figure 4] ] To check whether or not the device is a device that has completed the device registration through the process described above. In this case, step S220 may be omitted if the system is configured such that it is impossible for the phone APP to request a call to the call manager 244 when the device registration is not effectively completed.

Step S230: The call manager 244 transmits a SIP protocol call message to the VoIP call server 300 through the VoIP processing unit 245. [ At this time, by the translation of the line number of the LNT manager 243, the called party's terminal recognizes the telephone number of the smartphone 113 as a caller's telephone number 070-7777-1111.

The call manager 244 receives the call response message according to the SIP protocol from the VoIP call server 300 when the predetermined time has elapsed and the call manager 244 transmits the call response message according to the SIP protocol to the smart phone 113 A call session is established between the VoIP call servers 300 to establish a call path for the Internet call.

8 and 9 are conceptual diagrams illustrating the process of call pick-up of the telephone of the smart phone 113 by using the line number translation provided by the LNT manager 243 in the present invention. to be.

Step S310: First, the call manager 244 receives a call message according to the SIP protocol for a domestic telephone number (e.g., 070-7777-1111) from the VoIP call server 300 as a call is received from an external terminal device .

Step S320: Upon receiving the call message from the VoIP call server 300, the call manager 244 transfers the call to the Dex manager 241, thereby making a call to the Dex handset 112, which is basically connected to the residential gateway 200, Let events be delivered. At this time, the deck handset 112 rings.

Step S330: When the smartphone 113 operates the phone APP manager 242 by operating the call receiving button (menu) of the phone APP of the smartphone 113 without receiving a call from the deck handset 112, And sends a call pickup request to the call manager 244. [

Step S340: The LNT manager 243 inquires the database 246 in response to the call pickup request of the phone APP to confirm whether or not the smartphone 113 is a device that has completed device registration. Step S340 may be omitted if the system is configured such that it is impossible for the phone APP to request a call pickup to the call manager 244 unless the device registration has been effectively completed.

Step S350: As the smart phone 113 requests the call pickup, the call manager 244 cancels the call delivered to the deck manager 241. [ As the call is canceled, ringing of the deck handset 112 is also interrupted.

The call manager 244 provides a call response message in accordance with the SIP protocol to the VoIP call server 300 through the VoIP processing unit 245 so that the call manager 244 transmits the call response message according to the SIP protocol to the smart phone 113 And the VoIP call server 300 to establish a call path. The call partner 244 and the LNT manager 243 cooperate with each other to make the telephone number of the receiving terminal correspond to the telephone number of the receiving terminal even though the telephone number 010-1234-5555 is officially assigned to the smartphone 113 I think that it is telephone number 070-7777-1111 of the house.

10 and 11 illustrate a process of transferring a telephone call to the smartphone 113 by using the line number translation provided by the LNT manager 243, Fig.

Steps S410 and S420: It is assumed that a call session is established between the dex handset 112 and the VoIP call server 300 and a basic call path is established. In this state, the deck handset 112 transmits a call transfer request to the specific sub-number to the call manager 244 according to a user operation on the deck handset 112. [

Step S430: The LNT manager 243 inquires the database 246 in response to the call transfer request of the dex handset 112 to identify the smartphone 113 for the corresponding sub-number. For example, if the deck handset 112 requests a call transfer for the sub-number 01, the LNT manager 243 identifies that the terminal device corresponding to the sub-number is the smartphone 113.

Step S440: The call manager 244 forwards the call transfer request to the identified smartphone 113. Accordingly, the phone APP installed on the smart phone 113 displays a preset user UI corresponding to the call transfer request on the screen, and informs the user of the call transfer request.

Step S450: As the call pickup event is generated in the smart phone 113 by the user operation on the user UI, the smart phone 113 transmits the call transfer acceptance to the call manager 244.

Step S460: As the smartphone 113 accepts the call transfer, the call manager 244 resets the call session between the smartphone 113 and the VoIP call server 300 to form a transfer talk path. The call session between the VoIP call server 300 and the deck handset 112 is effectively canceled and a call session between the VoIP call server 300 and the smartphone 113 is newly established. However, it is recognized that the call session between the residential gateway 200 and the VoIP call server 300 is continuously maintained by the internal processing of the residential gateway 200.

In the above, VoIP service which can operate various kinds of terminals integrally with internet telephone service through a residential gateway is described. However, the technical idea of the present invention is not limited to the residential gateway, but can be generally implemented in various devices that integrally provide a voice and a wireless LAN service through a network.
