Abstract: The storage unit stores therein authentication IDs that are used for authentication of users and address information in association with one another. The authentication processing unit receives from a PC an authentication message that includes an authentication ID and is used for the authentication of the user of a communication terminal, and performs authentication on the user based on the received authentication message. The SIP address acquiring unit acquires from the storage unit address information that corresponds to the authentication ID included in the authentication message when the user is authenticated. The SIP address registering unit sends the SIP location server a registration request for registering the acquired address information as the address information of the user of the IP telephone terminal associated with the PC that transmits the authentication message.

Abstract: A switching equipment stores identification information of communication established with respect to an infrastructure network system in a storage unit, and when an access request is received from a terminal device, the switching equipment adds the stored identification information to the access request and transfers the access request to a 1× Radius server. When the terminal device having requested the access is authenticated, the 1× Radius server notifies a PANA PAA of address information of the terminal device associated with the identification information added to the access request. The PANA PAA approves the same network access as the switching equipment with respect to the terminal device in the received address information.

Abstract: A call-forwarding destination judging unit included in an SIP proxy estimates whether call forwarding will be required, based on the type of an SIP message. When it has been estimated that call forwarding will be required, the call-forwarding destination judging unit also estimates the destination of the call forwarding. With this arrangement, when the delivery of the SIP message requires call forwarding, it is possible to establish, in advance, a TLS connection with the SIP terminal being the destination of the call forwarding. Thus, it is possible to eliminate the need to establish the TLS connection at the time when the call is actually forwarded.
