    • A server by which time taken to establish a session can be shortened by reducing the number of messages exchanged between a destination terminal and the server and by which the manufacturing costs of terminals can be reduced. An IP version storage section included in the server stores an IP version implemented in the destination terminal under the control of the server. A message receiving section receives a message for establishing a session between a source terminal and the destination terminal from the source terminal. An IP version acquisition section acquires the IP version implemented in the destination terminal corresponding to the message from the IP version storage section. An IP version comparison section compares an IP version which is implemented in the source terminal and which is included in the message with the IP version which is implemented in the destination terminal and which is acquired by the IP version acquisition section. A comparison result sending section sends a result of the comparison by the IP version comparison section to an address converter which makes an address conversion so that IP versions of data frames exchanged between the source terminal and the destination terminal will match.
    • 可以通过减少目的地终端和服务器之间交换的消息的数量来缩短建立会话所需的时间的服务器,并且可以减少终端的制造成本。 包含在服务器中的IP版本存储部分存储在服务器的控制下在目标终端中实现的IP版本。 消息接收部分从源终端接收用于在源终端和目的终端之间建立会话的消息。 IP版本获取部分从IP版本存储部分获取对应于该消息的目的地终端中实现的IP版本。 IP版本比较部分将在源终端中实现并且包括在消息中的IP版本与在目的地终端中实现并由IP版本获取部分获取的IP版本进行比较。 比较结果发送部分将IP版本比较部分的比较结果发送给进行地址转换的地址转换器,使得在源终端和目的地终端之间交换的数据帧的IP版本将匹配。
