    • PROBLEM TO BE SOLVED: To provide a communication system which can respond to calling to a certain communication terminal from the communication terminal of an originator in the other communication terminal in a comparatively simple procedure. SOLUTION: The communication system which performs a communication according to the communication protocol of an SIP includes a first communication terminal Bob, and a second communication terminal Bill. The second communication terminal Bill has a means for transmitting an alternative response control message to the first communication terminal Bob when the first communication terminal Bob receives the incoming message from an originator communication terminal Alice. The first communication terminal Bob has an incoming message transfer means for transferring the incoming message from the originator terminal Alice to the second communication terminal Bill, and a response message transmitting means for transmitting the response message including contact information for specifying the second communication terminal Bill to the originator communication terminal Alice when the alternative response control message is received. A call is established between the communication terminal Alice for originating and the second communication terminal Bill. COPYRIGHT: (C)2006,JPO&NCIPI
    • 要解决的问题:提供一种可以以比较简单的过程从另一通信终端中的发起者的通信终端响应于某个通信终端的呼叫的通信系统。 解决方案:根据SIP的通信协议执行通信的通信系统包括第一通信终端Bob和第二通信终端Bill。 当第一通信终端Bob从始发者通信终端Alice接收到输入消息时,第二通信终端Bill具有用于向第一通信终端Bob发送替代响应控制消息的装置。 第一通信终端Bob具有用于将来自发起方终端Alice的输入消息传送到第二通信终端Bill的输入消息传送装置,以及响应消息发送装置,用于将包括用于指定第二通信终端Bill的联系信息的响应消息发送到 当接收到替代响应控制消息时,发起者通信终端Alice。 在用于发起的通信终端Alice和第二通信终端Bill之间建立呼叫。 版权所有(C)2006,JPO&NCIPI
