[Problem] To achieve a voice communication system which communicates between two networks that use partially overlapping address spaces. [Solution] According to the present invention, first and second networks are connected to one another by means of a gateway device provided with: a first protocol stack which manages transmission and reception addresses of communication packets in the first network; a second protocol stack which manages transmission and reception addresses of communication packets in the second network; and a call control unit which, upon reception of a communication packet from either network, determines the transfer destination network and transfer destination address of the packet on the basis of call destination information included in the packet.

Relaying device, method of relaying communication packet and voice communication system

[Problem] To smoothly update configuration data comprising: fixed data set to a server by an administrator; and data rewritable by a user at a terminal. [Solution] A terminal device having a storage unit that stores configuration data, and a first and a second provisioning server are connected over a network. The terminal device includes an operation unit for rewriting variable data, which is a part of the plurality of configuration data. The first provisioning server stores all the configuration data. The second provisioning server stores fixed data, which is the plurality of configuration data excluding the variable data. The terminal device accesses the first provisioning server in an initial state in order to obtain all the configuration data and store the same in the storage unit. The configured terminal device accesses the second provisioning server in order to obtain the fixed configuration data.

Data configuration system, data update system, and data configuration method

[Problem] A data update system of the present invention allows a user to update a data of a server while security of the server is maintained. [Solution] The present invention is provided with a main server for storing a configuration data, a terminal device to which update data for updating a part of or whole of the configuration data is input, a remote configuration device for communicating with the terminal device for receiving and storing the update data input to the terminal device, and a communication server for communicating with the main server and the remote configuration device. The remote configuration device transmits the update data received from the terminal device to the communication server. The communication server updates the configuration data stored in the main server with the update data received from the remote configuration device.

Data update system, remote configuration device and data update method

A communication control device includes an association table updater and a correction packet transmitter. The association table updater updates, when receiving from a first wireless device a packet containing an identification number of a first communication terminal connected to the first wireless device, an association table storing an address of the first wireless device and the identification number of the first communication terminal. The correction packet transmitter transmits, when a packet received from a second wireless device to which a second communication terminal is connected contains an address of the second wireless device, an identification number of the second communication terminal, and an identification number indicating a destination of the packet, and when the identification number indicating the destination is the identification number of the first communication terminal stored in the association table, a correction packet containing the address of the second wireless device and the identification number of the second communication terminal to the first wireless device after the packet is transmitted to the first wireless device.

Communication control device, wireless device, communication control system, communication control method and program

[Problem] To provide a communication system for simplifying terminal device configuration. [Solution] A communication system comprises a server and a terminal device. The server stores first information in order for the terminal device to communicate, and stores second information in order for the terminal device to connect to a network of the other bases. When the power is turned on in a normal operation, the terminal device connects to the network by using network information in a non-volatile memory unit, obtains the first information from the server, and writes the same in a volatile memory unit. Thus, the terminal device starts operation. When the power is turned on by using a particular operation, the terminal device connects to the network by using the network information in the non-volatile memory unit, obtains network information of the other bases from the server, and stores the same in the non-volatile memory unit. Thus, it is possible to connect to the network of the other bases.

Terminal device and terminal configuration system

[Problem] To conduct a process of moving a designated communication terminal belonging to a first communication system so as to belong to a second communication system without errors. [Solution] A management device is provided, which deletes information on a communication terminal of a first configuration device and then adds information of the communication terminal to the second configuration device. The management device is provided with an interface unit and a control unit. The interface unit obtains a first configuration file which stores a configuration data on a communication terminal belonging to a first communication system, and a second configuration file which stores a configuration data on a communication terminal belonging to a second communication system. The control unit deletes a configuration data of a designated communication terminal from the obtained first configuration file, and adds a configuration data of the designated communication terminal to the obtained second configuration file.
