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.

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.

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.

In a home agent for designating a transmission period of a binding update packet transmitted from a mobile node, a central processing monitor detects a usage rate of a CPU for processing accompanied by a reception of a binding update packet from the mobile node or a binding renewal message among the binding update packets, a line usage rate monitor detects a line usage rate of a receiving interface accompanied by the processing or a transmitting interface, a BC number monitor detects a binding cache number, and a calculator calculates a transmission period of the binding renewal message of the mobile node based on the thus detected CPU usage rate, line usage rate, binding cache number, and a priority table of the mobile node.

Home agent for getting information a line usage, a CPU usage rate, and a registered node number, and for adjusting transmitting period from a mobile node

The present invention concerns a mobile packet communication system that supports data communications, including Internet communications, in a high-speed mobile communication system such as a cellular communication network, and integrates a mobile network and a fixed network on a common platform while providing the capability to select an optimum route. Location registration servers--to--each store in a one-to-one fashion the addresses of subscriber nodes--to--currently serving mobile terminals--to--each assigned a packet address, or store in a one-to-one fashion the addresses of gate nodes--to--connected to fixed equipment--to--each assigned a packet address, and a transmitting node, which is a subscriber node or a gate node, temporarily stores a receiving node address reported from the corresponding one of the location registration servers--to--, and transfers subsequent packets directly to the receiving node by using the temporarily stored receiving node address.

An anisotropic exchange spring magnet powder complexing a hard magnetic material and a soft magnetic material, wherein a rare earth metal element, a transition metal element, boron and carbon and the like are contained, and the hard magnetic material and soft magnetic material have crystal particle diameters of 150 nm or less. A method of producing an anisotropic exchange spring magnet powder comprises treating a crystalline mother material containing a hard magnetic material and soft magnetic material or the crystalline mother material having amorphous parts, in a continuous process composed of an amorphising process and the following crystallizing process, repeated once or more times. An anisotropic exchange spring magnet is obtained by treatment, in an anisotropy- imparting molding process and a solidification process, of an anisotropic exchange spring magnet powder.

A communication method is capable of preventing an occurrence a change of a route for an underway communication between a mobile node and a correspondent node in a communication network and restraining an unnecessary packet from being forwarded to the correspondent node from the mobile node. The communication method is executed among the mobile node having a home address assigned in a first network and a temporary address assigned in a second network, an agent device surrogating a communication using the home address in the first network and a correspondent terminal communicating with the mobile node through the agent device. When the mobile node moves to the second network, the mobile node transmits information containing the temporary address to the correspondent node, and the correspondent node receives the information containing the temporary address and transmits the information to the temporary address of the mobile node.

Communication method

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.

In a router and a communication network system reserving network resources in compliance with an RSVP (Resource ReSerVation Protocol), that is a protocol for resource reservation, a router stores an encapsulated destination address associated with an address of a second host upon encapsulating and transferring a packet addressed to the second host, transfers a first path message transmitted from a first host to make a resource reservation in compliance with a resource reservation protocol, obtains thereafter the encapsulated destination address from the address of the second host, and transmits a second path message in a non-capsulated state to make a resource reservation with the same communication quality as that of the first path message to the encapsulated destination address.
