摘要： To implement a calling party number anonymous service in an IP telephone service. An IP telephone terminal adds the setting of requesting a Pool IP address along with a normal IP address to a REGISTER message directed from the IP telephone terminal to an SIP server and requests the assignment of a temporary IP address if receiving an anonymous call incoming request message. The SIP server makes the temporary assignment of the Pool IP address and notifies the temporary IP address to a called party IP telephone terminal by adding it to an INVITE message, if the called IP address of the anonymous call incoming request INVITE message is the IP telephone terminal. The called IP telephone terminal receiving the assignment of the temporary IP address can make the connection, communication and disconnection processes employing the temporary IP address as the self IP address in the following dialog.

摘要： The access server receives an authentication packet including an authentication result, a port change setting information, a port change time, a filtering setting information and a filtering time from the authentication server. The access server stores the respective information in the authentication packet into a memory. The access server refers to the memory, and in the case where the port change setting information on an arbitrary user identifier is set to perform port change, when it becomes the port change time, the access server changes the output destination of a packet from a user terminal to, for example, a proxy server B from a proxy server A. Besides, in the case where the filtering setting information on an arbitrary user identifier is set to perform filtering, when it becomes the filtering start time, the access server performs filtering on the port to which the user terminal is connected.

摘要： In a wide area Ethernet network, an edge side gateway (EGW) acquires layer 2 tunneling control information from an authentication server when a PADI is received from a user terminal, stores the correspondence between the source address of the PADI and the layer 2 tunneling control information in its management table, encapsulates the PADI in accordance with the layer 2 tunneling control information, and transmits the encapsulated PADI packet to the wide area Ethernet network. A core side gateway (CGW) having received the encapsulated PADI packet stores the correspondence between the tunneling control information and the source address extracted from the received packet in its management table, and forwards the PADI obtained by decapsulating the received packet to a broadband access server. Thereafter, each of the EGW and CGW forward received packets for the user after converting their format by referencing to the management tables.

摘要： A gateway selector and a load distribution management device are provided between a user terminal and plural gateway devices. Of response packets received from the plural gateway devices, the gateway selector selects a response packet from a gateway device with a higher priority, according to the priority in a load distribution management table of the load distribution management device. Then, the gateway selector transfers the selected response packet to the user terminal, while discarding a response packet from another gateway device. In this way, it is possible to construct a redundant configuration of the gateway devices, independent of user terminal implementation.

摘要： When a user terminal makes a connection request, a router acquires a group address that the user terminal can join from an authentication server. The router gives information of the router to a packet during joining check (Query) and transmits the packet to a layer 2 switch. The layer 2 switch can grasp, by receiving the joining checks which group address the user terminal can join. The layer 2 switch can perform delivery control involving authentication. The layer 2 switch collects information necessary for accounting such as delivery start and end times and traffic and transmits the information to the router. The router creates accounting information on the basis of the information and transmits the accounting information to the accounting server.
