Benefits of technology

[0010] It is therefore an object of the present invention to provide a communication system using a home gateway device and an access server device which are capable of preventing attacks from the malicious...

Problems solved by technology

In this case, it is also expected that the security will become a potential problem.
In this regard, in the case of the home network, it is practically unrealistic to require the existence of a network manager who can make appropriate setting regarding the security with respect to the home gatewa...

Embodiment Construction

[0027] Referring now to FIG. 1 to FIG. 11, one embodiment of a communication system using a home gateway and an access server according to the present invention will be described in detail.

[0028]FIG. 1 shows an exemplary overall configuration of a communication system in this embodiment.

[0029] As shown in FIG. 1, a home gateway 2 and various digital home electronics such as home electronic devices, AV devices, PCs, etc. (a lighting instrument 11 and a VTR 12 are shown as examples in FIG. 1) are connected to a home network 1 in the home. The home network 1 can be formed in practice by using multiple network technologies such as IEEE 1394 and Echonet, for example. Also, the devices connected to the home network 1 are not necessarily compatible with the Internet protocol.

[0030] The home gateway 2 is connected with an access network 3. The access network 3 is a portable telephone network, for example. An access server 4 is connected to the access network 3, and the access server 4 is...

Abstract

In a communication system using a home gateway device and an access server device, the security function for the home network side is provided by the access server device on the service provider side, so that it becomes possible to prevent attacks from the malicious users with respect to the home network, without implementing excessive security functions in the home gateway device on the home network side and without requiring professional skills for setting and management to the user of the home gateway device.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a communication system using a home gateway device to be provided at a home network and an access server for controlling accesses to the home gateway device. [0003] 2. Description of the Related Art [0004] In conjunction with the rapid spread of digital home electronics, the so called “home network” for connecting home electronic devices together is becoming popular quickly. This is the phenomenon that is not limited to any particular fields, as exemplified by the IEEE 1394 for AV devices, the Echonet for home electronics, the Ethernet or USB for PCs and peripheral devices, etc. [0005] There is a trend to connect such home networks with the Internet and provide the Internet connection function to the home electronic devices or enable control of the home electronic devices from the Internet. To this end, there is a need for a device called “home gateway” which is to be located between...
