Abstract: A communication system includes communication protocols that allow a single network or multiple neighboring networks to increase resource sharing and reduce mutual interference and increase their overall throughput. Various protocols apply to homogenous networks in which all power line communication (PLC) devices of multiple networks are interoperable with respect to full power line communication in a common PHY and to heterogeneous networks having non-interoperable PLC networks which do not employ a common PHY. As to heterogeneous networks, a protocol herein enables coexistence via a special signaling scheme. In homogeneous networks, all nodes can communicate with each other using a common PHY, so that information about one PLC network can be transferred to another PLC network. In heterogeneous networks, not all PLC networks can exchange information using their own native PHY.

Abstract: The present invention includes a repeater and a server for controlling access, from a terminal of an outside network, to the server of an inside network. The repeater and the server permit a packet transmission from the terminal to the server under limited conditions. When the server acknowledges a connection for the permitted packet, transmission conditions for packets to be sent to the server are loosened. Subsequently, packet transmission between the terminal and the server is controlled under the loosened transmission conditions. As for encrypted packets, the server decodes the encrypted packets and notifies the repeater of relevant information.

Abstract: A terminal comprises a packet receiving unit, a packet sending unit, a link-state detecting unit that detects a link-up to a switching device, a configuration-change notifying unit, and a resource reservation table. When the link-state detecting unit detects a link-up, the terminal notifies network configuration information and network resource reservation information to a management device. When a link state is changed, the management device can immediately manage the network based on the latest network configuration information and the latest network resource information.

Abstract: The present invention introduces a plurality of resource management devices (M1)-(M4). Each resource management device comprises a resource reservation information transmitting unit (205) and a resource reservation information receiving unit (206). Thus, even when one of the resource management devices is inactivated, the resource management can be continued. Since reserved resource information is shared among a plurality of resource management devices, if exist, the resource management can be performed without contradiction. Processing load can be decentralized by processing a resource reservation request by the plurality of resource management devices.

Abstract: The communication system supports reservation of network resources. The base stations relay packets among the terminals, and perform priority control based on the priority set to the packets. In the terminal, the communication-managing table stores communication information of own terminal and a partner thereof. The packet-transmitting unit, setting priority to the packets, transmits the packets. When link condition of own terminal change, the link-managing unit updates, in order to prevent from quality deterioration of the other terminals, the priority of each of the packets whose source terminal is the own terminal.

Abstract: User information related to a predetermined user, including a user ID, is obtained from a server on a network. Telephone book information, including the user ID and a telephone number of a communication apparatus that the predetermined user uses, is input on an operation unit of the present communication apparatus. The user information and the telephone book information are stored while being associated based on the user ID. The telephone book information associated with the user information based on the user ID is displayed as secondary information of the user information, when the user information of the predetermined user is displayed on a display and when display of further information of the predetermined user is instructed.

Abstract: Access from a terminal of an outside network to a server of an inside network is put under control. A repeater and the server permit a packet transmission from the terminal to the server under limited conditions. When the server acknowledges connection for the permitted packet, the transmission conditions for packets to be sent to the server are loosened. After then, packet transmission between the terminal and the server is controlled under the loosened transmission conditions. As for encrypted packets, the server decodes the encrypted packets and notifies the relevant information to the repeater.

Abstract: A resource request is continuously accepted within predetermined time by a resource management device that comprises a resource request accepting unit, a measuring unit, and an allocating unit. The resource request accepting unit accepts a resource request that is necessary for communication. The resource request includes priority of communication. The measuring unit measures the accepting time when the resource request accepting unit accepts the resource request. The allocating unit allocates resource to the resource request accepted in accepting time based on priority. As a result, suitable resource allocation according to the priority instead of the order of arrival is realized.
