摘要:
In a node device which is part of a communication system with a terminal and a location registering server, a node device on a receiving side transfers, to a destination node device, a received inter-node packet, based on destination terminal location information stored in its storage portion or based on a location registering server, directly or through other devices, or the destination node device notifies a former node device (on the receiving side) of an address of its own device and the destination terminal directly or through other devices. Also, the node device on the receiving side or the destination node device notify a source node device of the address of the destination node device and the destination terminal directly or through other devices, based on a predetermined address stored in the storage portion of the terminal, the node device, or the location registering server.

The present invention relates to a handover technique used in a mobile communications system. For instance, a mobility management node selects an access line to be used for transferring application data, on the basis of the type of application data (http, ftp, voip, or the like) to be transferred from a communication node at the other end to a mobile node, and transfers the application data by means of the selected access line. As a result, a plurality of access lines connected simultaneously to the mobile node can be used according to the type of application, such as http, ftp, voip, or the like. Therefore, the quality desired by a user is ensured, and an attempt to effectively utilize a network can be realized.

Data from an STM (Synchronous Transfer Mode) network is converted into an ATM (Asynchronous Transfer Mode) cell by an interworking facility, and the ATM cell is input to the ATM network. If the input cell corresponds to a connection which requires voice processing, a voice processing trunk within a switch performs the processes such as an echo compensation process, an encoding process, a multiplexing process, etc. The switch outputs the cell to a trunk line of the ATM network.

A bulk exchange-spring magnet 12, a method of producing the same, and a device 20 incorporating the bulk exchange-spring magnet are disclosed. The magnet includes magnet powders 10 having hard and soft phases, and boron and oxygen atoms which cohere in boundary areas 16 between grains 14 of the densified magnet powders 10. In a production method, the magnet powders 10 are compacted so as to incorporate boron and oxygen atoms into the boundary areas 16 and are heated under a compacted state of the magnet powders at varying operating temperatures for a given time period. This results in formation of a highly densified magnet at a lower potential operating temperature for a shorter time period without the grain growth. The device 20 includes the bulk exchange-spring magnet 12 containing the boron and oxygen atoms cohering between the grains of the densified magnet powders.

A short cell multiplexer includes a sequence designating unit, in which reading intervals corresponding to QOS classes are set in respective reading interval setting registers. A counter memory is stored with the number of timings at which the short cells can be read. The sequence designating unit specifies the QOS class in which the number of timings reaches the reading interval on the basis of the reading interval and the number of timings, and gives to a reading unit an indication of reading the short cell belonging to this class.

A storage unit includes an alarm state/timer table, an alarm state table, an alarm state OR-representation table, an alarm state change OR-representation table, an alarm state latch circuit, and a statistical information memory. A collection unit extracts the identifier and data from a cell that passes through a switching unit. An update unit updates associated data in the storage unit. A readout unit reads the updated data and sends it to a call processing processor. An address generation section selectively generates the address for data needing to be updated. An adjustment section forces the readout unit to wait until a cell slot arrives in which no data is updated.

An interconnection structure for semiconductor integrated circuits and the method for manufacturing of the same are provided. The interconnection structure has a low electric resistance and a good electromigration resistance and can prevent the atoms in wire materials from diffusing into insulating films or substrates. More particularly, an insulating film 12 is formed on a silicon substrate 10, on which a tungsten 14 is formed. The tungsten film 14 is subjected to plasma irradiation on the surface thereof to form an amorphous W--N film 16. A copper wire pattern 20 is formed on the amorphous W--N film 16.

In a load balancer preserving a function of server consistency maintenance during communications even if a terminal is a mobile terminal, identifying information specific to a mobile IP terminal is extracted from an arrival packet, and a destination server to be connected is determined based on the identifying information. Also, a home agent or a terminal is requested to notify a change of the care-of address when the care-of address of the terminal has changed, and a destination server to be connected is determined by regarding the notified care-of address as identifying information.
摘要:
The present invention discloses a load decentralization method for decentralizing load centralized to a MAP of a hierarchical domain in a network where packets destined to mobile nodes in the network are transmitted to the mobile nodes via the MAP, in which the MAP includes a table part for managing a corresponding relation of home addresses and Care-of-Addresses of the mobile nodes in the hierarchical domain. The method includes the steps of providing a same function as the MAP to at least a portion of routers situated in the hierarchical domain of the MAP, moving one of the elements in the table part to the portion of the routers when a congestion of the MAP is detected, and actuating the portion of the routers to operate as a substitute of the MAP.
