Abstract: A first terminal notifies an LFC service functional unit of LFC package related information for customization of a second terminal, an address of the second terminal to be customized, and an account of the user of the first terminal to a contents provider. As a result, the LFC service functional unit acquires an LFC package from the contents provider, then the LFC service functional unit customizes the second terminal based on the obtained LFC package.

Abstract: A communication module-cooling structure includes a main body section to be cooled by a cooling mechanism, and a heat sink including a cooling receiving section including partition walls and slit-shaped receiving spaces defined by the partition walls. The receiving spaces of the cooling receiving section receive communication modules, and each of the communication modules includes a substrate mounted with a communication circuit component thereon and first and second sidewalls which sandwich the substrate therebetween in a thickness direction of the substrate. At least one of the first and second sidewalls of each of the communication modules is in surface contact with an inner surface of each of the receiving spaces.

Abstract: A communication device transmits to a relaying device a transmission right grant request for requesting a grant of a transmission right to a transmitting device, and the relaying device determines whether the received transmission right grant request is a command associated with the transmission right of the communication device or a command associated with the transmitting device, and if it determines that it is the command associated with the transmitting device, it grants the transmission right to the transmitting device, and starts broadcasting of data being transmitted from the transmitting device. In addition, when receiving from the communication device an operation command for operating the transmitting device, the relaying device determines a type of the command and transmits it to the transmitting device.

Abstract: In order to appropriately deliver content data to users participating in a teleconference, following steps are executed: receiving a URI of the content data to be delivered to participating users participating in the teleconference from the user terminal of a specific participating user; obtaining the content data corresponding to the URI from a server relating to the received URI, and storing the content data into a content data storage device; and transmitting the content data stored in the content data storage device to the user terminals of the participating users. Only by designating the URI, the server for the teleconference obtains and transmits the content data corresponding to the URI. Therefore, it is possible to use the content data regardless of the access authority of the participating users.

Abstract: An optical transmission module has: an optical module having an optical element and a receptacle portion; a circuit board that is electrically connected to the optical module through an electrical connection member; and a housing in which the optical module and the circuit board are placed. The optical module is in surface-contact with and fixed onto the housing. The receptacle portion and the circuit board are not in contact with the housing. The receptacle portion is restricted in position while having a positional degree of freedom at least in a direction perpendicular to an optical axis of light emitted from the optical element. The circuit board is restricted in position while having a positional degree of freedom at least in a direction of the optical axis.

Abstract: An optical transceiver has: an optical subassembly that has a built-in chip portion and a receptacle portion; a board electrically connected to one end of the built-in chip portion; a housing that houses the optical subassembly and the board; and a holding member to hold the optical subassembly.

Abstract: A mounting structure for electronic components is provided with a circuit board that has a step portion formed at one end portion thereof. The step portion is sandwiched by a lead of the electronic component so as to secure the lead to the step portion. The step portion is formed by perforating a region on one surface of the circuit board, and then peeling a part of the circuit board corresponding to the perforated region so as to reduce the thickness of the circuit board at the region.

Abstract: An optical transceiver has: an optical subassembly (OSA) having a built-in optical element and a cylindrical receptacle to conduct an optical path from the optical element; a chassis having an entrance that allows insertion of an optical fiber to be connected to the optical path; an OSA holder engaged with the receptacle to hold the OSA and accommodated in contact with an inside portion of the chassis; and an OSA holder-regulating portion formed in the chassis to regulate the OSA holder, the OSA holder-regulating portion being positioned opposite the entrance relative to the OSA holder.

Abstract: A communication control method of this invention includes: when a call-in request to a chat for another participant in a voice-based teleconference by a first participant of the voice-based teleconference is received, transmitting the call-in request to the chat to a terminal of another participant; and when a participation response to the chat by another participant is received, carrying out a presence management setting so as to enable the first participant and a participant replying the participation response to update and subscribe dialogue contents of the chat, which are managed as presence data delivered to subscribers when updated. Thus, by using the presence technique, it becomes possible that the conference is shifted from the voice-based teleconference to the character-based teleconference and both of the conferences coexist.

Abstract: An MPLS network is hierarchized into upper and lower layer MPLS networks, in which the upper layer MPLS network has TE-LSP for a resource guarantee set up in a mesh form, and at least one lower layer MPLS network has TE-LSP for a resource guarantee set up in a mesh form independently of the upper layer MPLS network. TE-LSP's for a forwarding resource guarantee are set up between routers within the lower layer MPLS network and a gateway router designated within the upper layer MPLS network, and connected to the TE-LSP set up within the upper layer MPLS network.
