摘要:
A voice call communication switching system in which a first network and a second network are connected to each other and which includes a user equipment that establishes communication using the networks and an application server that controls communication exchanged. The application server includes a message control unit that receives a message to be sent from the user equipment when a situation is changed from one where the user equipment communicates with another user equipment using resources of the first network to another where the user equipment communicates with the another user equipment using resources of the second network and a session end requesting unit that sends a resource release instruction to disconnect the communication between the first network and the user equipment to the user equipment. The user equipment includes a resource releasing unit that sends a message indicating release of the resources to a node.

A UPC (cell flowing ratio controlling) function is executed when a plurality of channels are multiplexed in single device. The cell flowing ratio control method and system on a cell switching system for receiving arrival cells transmitted from a plurality of channels and controlling to pass the received cells multiplexes the arrival cells flowing on the plurality of channels; increases only a time counter corresponding to a channel to which an arrival cell is belonging, the time counter being selected from a plurality of time counters provided for the plurality of channels; and controls cell flowing ratio correspondingly to counted value of the increased time counter.

A heat-resistnat wire is disclosed which comprises a line of copper or aluminum coated with a shielding material obtained by heating a mixture of: (A) an ethylenic copolymer comprised of ethylene and 0.1 to 20.0 mol % of a monomer of at most 30 carbon atoms having an oxirane group or a hydroxyl group and having at least one double bond; and (B) an ethylenic copolymer comprised of ethylene and 0.1 to 20.0 mol % of a monomer possessing a functional group capable of reacting with oxirane group or hydroxy group in the ethylenic copolymer (A). The wire is excellent not only in heat resistance but also in insulating ability and flexibility.
摘要:
Identification information which identifies a specific area zone that is part of a cell of a radio base station is transmitted from the radio base station to a mobile terminal. Subsequently, when the mobile terminal is located at the area zone specified by the identification information, communication quality between the mobile terminal and the radio base station is measured by the mobile terminal, and the quality information indicating the measured communication quality is transmitted from the mobile terminal to the radio base station.
摘要:
A control method in a mobile communication system, that includes configuring a discard timer corresponding to a service data unit (SDU) for discarding the SDU according to a value of the timer; maintaining the value of the discard timer corresponding to the SDU when a handover is performed without restarting or resetting the value of the discard timer; and discarding the corresponding SDU when the maintained value of the discard timer reaches a given value.
摘要:
A base station controlling apparatus 10a that causes a plurality of base stations 12a to synchronously distribute a plurality of packet data to a mobile terminal, including: a receiver S12 that receives a plurality of packet data; a transition information generator S14 that generates transition information corresponding to a sequence number of packet data used for switching a compression state when the plurality of packet data are compressed; a compressor S20 that compresses the plurality of packet data based on the transition information; and a transmitter that transmits the plurality of compressed packet data to the plurality of base stations, and transmits the transition information to another base station controlling apparatus.
摘要:
A node compares an address resolution result corresponding to first packet data that is sent by the user device for accessing a first content server and an address resolution result corresponding to second packet data having the sender of the first packet data as the local node. When the addresses are different, the node allocates the second address resolution result to the user device, and configures a communication path between the user device and a second content server indicated by the second address resolution result. The user device accesses to the second content server on the communication path using the allocated second address resolution result.
摘要:
A packet communication apparatus that carries out packet communication with a second packet communication apparatus via a logical connection through header processing of compressing or decompressing a packet header, the apparatus managing a first state machine of a first header processing state concerning a first packet flow of the connection and a second state machine of a second header processing state concerning a second packet flow of the connection; and controlling a state transition of a third state machine that is one of the first state machine and the second state machine on the basis of a state transition of a fourth state machine that is the other of the first state machine and the second state machine.
摘要:
A control method in a mobile communication system with a buffer unit for temporarily storing packet data to be sent, includes dropping the packet data stored in the buffer unit before sending when a drop timer corresponding to the packet data before sending reaches a given value or when a drop condition required by a drop mechanism accompanying the buffer unit is satisfied, and dropping the packet data stored in the buffer unit after sending when a drop timer corresponding to the packet data after sending reaches a given value.
摘要:
An active system routing device, upon receiving a location registration request sent from a mobile node, forwards the received location registration request to a standby system routing device. The standby system routing device stores a home address and a care-of address of the mobile node in a way that maps these addresses to each other based on the location registration request received from the active system routing device, monitors a status of the active system routing device and, upon detecting a fault of the active system routing device, executes switching over the self-device to an active system.
