Patent number: 7920550Abstract: A voice communication system, which is connected to a LAN to which communication terminals are connected and to a public network to which telephones are connected, is provided with a communication server between the LAN and public network having different protocols from each other. The communication server enables a voice communication between a telephone on the public network and a communication terminal connected to the LAN by performing processing similar to that for a voice communication between two communication terminals connected to the LAN. The communication server determines whether an address of the other party inputted by a user is a communication terminal address or a telephone number, and transmits a voice communication request to a communication terminal of the other party when the address is a communication terminal address.Type: GrantFiled: October 18, 2007Date of Patent: April 5, 2011Assignee: Hitachi, Ltd.Inventors: Naoko Iwami, Susumu Matsui, Keiko Takahara

Patent number: 6078583Abstract: A communication system and communication method adapted so that the user of one of the communication terminals can more easily communicate with another one connected to the internet through the public network. Connection management servers for relay and manage the communication are provided at nodes between the internet and the public network. Each of the connection management servers assigns an IP address to the communication terminal connected to the internet through the public network, and registers the IP address and the telephone number. When receiving a communication request, the connection management server specifies a communication route to the communication terminal on the basis of the telephone number of the called-side communication terminal set in the communication request. The server checks if the called-side communication terminal is connected to the internet on the basis of the above registration. If it is connected to the internet, the server relays the communication request.Type: GrantFiled: October 30, 1997Date of Patent: June 20, 2000Assignee: Hitachi, Ltd.Inventors: Keiko Takahara, Tohru Hoshi, Toshiaki Koyama

Patent number: 5905495Abstract: A communication system which can communicate with a party user even when an originator user of a communication terminal does not know the terminal address of a communication terminal of the party user with whom the originator user wants to communicate. When its own user A does not know the terminal address of a communication terminal of a user B, a communication terminal of the user A sends an outgoing file having its own terminal address stored therein as an electronic mail directed to the user B. When receiving the outgoing file as the electronic mail, the communication terminal of the user B displays an icon on its display unit to prompt the user B to enter an instruction of performing reply communication. In response to it, when the user B clicks a mouse on the icon, the communication terminal of the user B can perform the reply communication to the communication terminal corresponding to terminal address stored in the outgoing file.Type: GrantFiled: February 12, 1997Date of Patent: May 18, 1999Assignee: Hitachi, Ltd.Inventors: Noriyuki Tanaka, Keiko Takahara, Kazuma Yumoto, Naoko Iwami, Tohru Hoshi, Toshiaki Koyama, Susumu Matsui
