First Claim
Patent Images
1. A method of communications by making an access from a first communication device located outside a home network to a second communication device on the home network, the method comprising:
- transmitting a prescribed message from the first communication device to an access server device corresponding to a home gateway device provided at the home network by specifying an access number/address corresponding to the home gateway device;
carrying out an authentication procedure for authenticating the first communication device according to a prescribed authentication method between the access server device and the first communication device upon receiving the prescribed message at the access server device;
transferring the prescribed message through a prescribed access network from the access server device to the home gateway device corresponding to the access number/address specified by the prescribed message, when the authentication procedure is successfully completed; and
transferring the prescribed message from the home gateway device to the second communication device through the home network after converting the prescribed message according to a protocol supported by the second communication device, when the prescribed message is received by the home gateway device from the access server device which is registered at the home gateway device in advance.

4. An access server device for carrying out access control with respect to a home gateway device of a registered home network, comprising:
-
a memory unit configured to store an authentication table registering in correspondence a first access number to be used in accessing the home gateway device which is a target of the access control by the access server device, a second access number to be used in accessing the access server device at a time of transmitting a prescribed message from a first communication device located outside the registered home network at which the home gateway device is provided, to the home gateway device or a second communication device on the registered home network, and an authentication method to be used in an authentication procedure for authenticating the first communication device between the access server device and the first communication device;
a first interface unit configured to receive the prescribed message from the first communication device by using the second access number;
a processing unit configured to carry out the authentication procedure between the access server device and the first communication device using the authentication method obtained by referring to the authentication table according to the second access number used in the prescribed message; and
a second interface unit configured to transfer the prescribed message to the home gateway device through a prescribed access network by using the first access number obtained by referring to the authentication table according to the second access number used in the prescribed message, when the authentication procedure is successfully completed. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14)
