The present invention relates to a method and system for providing a home network service using a portable internet network. More specifically, the home network service through the portable Internet network in the home using a portable Internet (Portable Internet or WiBro: Wireless Broadband Internet) interface module as an external interface of the residential gateway. The present invention relates to a method and system for providing a home network service using a portable internet network.

Recently, due to the development of home appliances and communication technology, the home network that connects various devices to the network in the home is increasing. The gateway that performs network matching between the home network and the external access network in the home is called a residential gateway. .

FIG. 1 is a block diagram of a home network system according to the prior art. Referring to FIG. 1, an access network 120 and a home network 140 connected to a wide area network (WAN) 110 are illustrated. It can be seen that the wired residential gateway 130 is connected to the.

Here, the wired residential gateway 130 interfaces with data transmitted and received between the access network 120 and the home network 140. That is, a function that is located between the access network 120 and the home network 140 using different data communication protocols and converts the transmission data between two communication networks using different protocols into data suitable for each communication network. Do this.

The access network 120 mainly uses a wired network such as an xDSL network or a cable network, and the wired residential gateway 130 uses a phone-line networking alliance (PNA) port or a power line carrier (PLC) port as a main LAN interface. It uses xDSL modem or cable modem as main WAN interface.

Only one public IP address (Internet Protocol Address) is assigned to the wired residential gateway 130, and home network devices connected to the home network 140 are assigned a private IP that is not recognized externally. Accordingly, when the home network devices connected to the home network 140 want to receive information from the outside, the wired residential gateway 130 converts the private IP addresses of the home network devices into their public IP addresses.

On the other hand, when an external device wants to access the home network, the IP address of the wired residential gateway 130 needs to be known. Since the wired residential gateway 130 uses a floating IP, the IP address changes every connection. Therefore, in the home network server (not shown) connected to the WAN 110, the IP address of the wired residential gateway 130 should have its information whenever the IP of the wired residential gateway 130 changes.
