摘要： 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. When the address is a telephone number, the user acquires the communication terminal address of the communication server, and transmits a voice communication request to the communication server. Thereafter, the voice communication processing is performed through the communication server.

摘要： In a video communication system including a sending terminal and a receiving terminal connected via a packet switching network, a receiving terminal which has detected loss of a video packet sets a video output into a freeze status and transmits a refresh request command to the sending terminal. Upon receiving the refresh request command, the sending terminal requests a video coder unit to execute refreshing and transmits a series of video packets beginning from an INTRA frame. Upon receiving a packet of the INTRA frame, the receiving terminal releases the freeze status and restarts video information decoding.

摘要： 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. If it is not connected thereto, the notice that it is not connected is transmitted to the calling-side communication terminal. If it is not connected yet, the server regards the called-side terminal as having its telephone connected to the telephone channel, and causes speech transmission between that telephone and the calling-side communication terminal.
摘要翻译：一种通信系统和通信方法，其适于使得一个通信终端的用户能够更容易地通过公共网络与连接到因特网的另一个通信。用于中继和管理通信的连接管理服务器在互联网和公共网络之间的节点处提供。每个连接管理服务器通过公共网络向连接到互联网的通信终端分配IP地址，并且注册IP地址和电话号码。当接收到通信请求时，连接管理服务器根据在通信请求中设置的被叫侧通信终端的电话号码，指定到通信终端的通信路由。在上述注册的基础上，服务器检查被叫侧通信终端是否连接到互联网。如果连接到互联网，服务器将中继通信请求。如果不连接，则将其未连接的通知发送到主叫侧通信终端。如果尚未连接，则服务器将被叫侧终端的电话机连接到电话信道，并在该电话机和主叫侧通信终端之间进行语音传输。
