2 is a functional block diagram illustrating a home network terminal apparatus according to the present invention.
3 is a flowchart illustrating a method of controlling a home network terminal apparatus according to the present invention.

Hereinafter, a home network terminal apparatus and a control method according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 is a functional block diagram illustrating a home network terminal apparatus according to the present invention. 2, a home network terminal 100 according to an exemplary embodiment of the present invention includes a wireless connection unit 110, a home Internet connection unit 120, a network connection unit 130, a home appliance connection unit 140, And a control unit 150.

The wireless connection unit 110 performs wireless communication with the smart terminal 20. At this time, it is preferable that the wireless connection unit 110 and the smart terminal 20 perform communication using a WIFI communication protocol, and it is preferable to use a private IP address. At this time, it is preferable to allocate the private IP address more than the IP address of the minimum C-class.

The home Internet connection unit 120 is preferably connected to the external Internet 11 to support the Internet service of the wall pad 160 and to support a public IP address.

In addition, only the network connection 130 can only be connected to the network 12, such as other home network terminals (not shown), a management room 12-1, a lobby phone 12-2 and a security room 12-3. .

It is preferable that the in-house unit connection unit 140 is connected to the home controller or home appliances, the information communication apparatus, and the detector. That is, when the home network environment is connected with all household appliances and information communication devices in the house, the user can control the household appliances by using the wall pad 160, . That is, it is an interface that can automatically control security, lighting, temperature, etc. in the home through the wall pad 160.

The control unit 150 routes packets to the home Internet connection unit 120, the network connection unit 130, and the internal device connection unit 140 according to destinations of packets received through the wireless connection unit 110.

It is preferable that the control unit 150 confirms a destination address of a packet received through the wireless connection unit 110 and routes the packet to the network 12 and the external Internet 11 only according to the confirmed IP address Do.

That is, the control unit 150 confirms the L3 layer destination address of the packet received through the wireless connection unit 110 and connects to the management room 12-1, the lobby phone 12-2, and the guard room according to the checked IP address The packet is routed to the home Internet connection unit 120 connected to the network 12 and the external Internet 11 only. For example, when the destination IP is included in the network IP classd only, the packet is forwarded only to the network connection unit 130, and the packet having the other purpose IP is transmitted to the home Internet connection unit 120 using the NAT do.

At this time, only the network connection 130 (130) connected to the network 12 by applying static routing to the IP address used in the network 12, for example, the destination IP included in the 10.0.0.0/8 A- Or to the in-premises device connection unit 140. FIG.

In addition, the controller 150 performs an address conversion for replacing an IP address used in the in-house internet network with a public IP address for an IP packet forwarded to the public network only when the network is connected from the network 12 to the external Internet 11 It is possible. That is, since the private network only uses the private IP address in the private network in the network 12, when the user connects from the network 12 to the Internet network, the controller 150 transmits the IP packet forwarded to the public network to the public IP network The address translation is performed in order to replace the IP address used in the in-house internet gateway, and then the address translation is performed to the in-house internet connection unit 120.

Accordingly, the present invention has an effect of solving the problem that some functions can not be used to connect to the external Internet 11, the home-use apparatus, or simply connect to the network 12 through the Smarth terminal.

Therefore, even if the address field is converted in the IP packet, it is necessary to perform the correction of Checksum, TCP seq, TCP ack, etc. in addition to the substitution of the address field in order to provide a converted view between the hosts and to ensure proper operation of the IP protocol and higher protocols . Accordingly, the controller 150 can use static NAT, dynamic NAT, and masquerading.

The control unit 150 manages the IP address of the unique area for each household to manage the IP address for each home network, and may manage the corresponding IP address area so that IP conflict does not occur only in the network 12 .

For example, the control unit 150 can manage via DHCP. DHCP is a protocol that allows network administrators to centrally manage and assign IP addresses on a network within an organization. In the Internet TCP / IP protocol, each computer must have a unique public IP address to access the Internet. When computer users in the organization connect to the Internet, the IP address must be assigned to each computer.

If DHCP is not used, the IP address must be manually entered for each computer. If the computer is moved to a location in another part of the network, a new IP address must be entered. DHCP allows network administrators to centrally manage and assign IP addresses, and to automatically send new IP addresses when a computer is connected to another part of the network.

Here, it is also possible to separate the DHCP areas from each other in order to manage the DHCP in the port and the home network that are connected to the network 12 only. That is, in order to perform IP management for each home network, a unique domain is managed for each household, and the corresponding IP domain is managed such that IP conflict does not occur in the network 12 only.

When receiving a DISCOVERY packet for searching for a DHCP server from a device connected to the home network, the control unit 150 broadcasts only the home network area and transmits the DHCP packet to the home network connection unit 130 connected to the network 12 only. Lt; RTI ID = 0.0 > forwarding < / RTI > That is, when receiving a DISCOVERY packet to search for a DHCP server in a home network device connected to a home network (meaning a network to which domestic devices are connected), the controller 150 broadcasts only in the home network area and is connected to the network 12 Filtering can be done to prevent DHCP packets from being forwarded to WAN2. In addition, since the DHCP packet received from the network 12 is filtered, the DHCP packet can be distinguished from the DHCP area managed in the home network.

The controller 150 may support IP address assignment or static IP address assignment using DHCP according to the IP network connection method. Meanwhile, when there is a change in the policy of the IP address provided to the smart terminal 20, the terminal device, and the complex network 12, the controller 150 may update the IP address of the corresponding terminal .

A home network terminal apparatus control method according to the present invention will be described with reference to FIG.

First, it is determined whether the destination address of a packet received from the wireless connection unit 110 performing wireless communication with the smart terminal 20 is only the network 12 (S110).

In step S110, if the address of the packet is only the network 12 (YES), the packet is routed only to the network connection unit 130 (S120). It is preferable that the step (S120) confirms the destination address of the packet received through the wireless connection unit 110 and routes the packet only to the network 12 and the external internet 11 network according to the confirmed IP address Do.

That is, the step (S120) checks the L3 layer destination address of the packet received through the wireless connection unit 110, and transmits the L3 layer destination address to the management room 12-1, the lobby phone 12-2, And routes the packet to the home network connection unit 120 connected to the external network 11 and the connected complex network 12. For example, when the destination IP is included in the network IP classd only, the packet is forwarded only to the network connection unit 130, and the packet having the other purpose IP is transmitted to the home Internet connection unit 120 using the NAT do.

For example, if only the network 12 is used by applying static routing to the destination IP included in the 10.0.0.0/8 A-Class IP network in which the IP address used in the network 12 represents only the network 12, The connection may be routed to only the network connection 130 or the in-premises connection 140. [

On the other hand, if it is determined in step S110 that the packet address is the external Internet 11 network (NO), the received packet is converted into a public IP address and is routed to the Internet connection part (S130). That is, since only the private IP address is used in the private network only in the network 12, when the connection is made from the network 12 to the Internet network, in the step S130, the IP packet forwarded to the public network is transmitted to the public IP network The address translation is performed to replace the IP address used in the home Internet network, and then the address translation is performed to the home Internet connection unit 120.

In addition, in order to manage an IP address for each home network before a packet is received through the wireless connection unit 110, an IP address of a unique region is managed for each generation, You can also manage the IP address space.

In the step of managing the IP address area, when receiving a DISCOVERY packet for searching for a DHCP server from a device connected to the home network, the IP address area broadcasts only in the home network area, ) To prevent the DHCP packet from being forwarded.

In addition, the step of managing the IP address area may support IP address allocation using DHCP or static IP address setting according to the IP network connection method.
