摘要： A mobile communications network and data delivery method in a mobile communications network is provided that can implement connectionless transfer in the mobile communications network, and obviate the need for sending a call control signal for data delivery. An IP address is assigned to each of the nodes of the mobile communications network including routing nodes (a gate node and repeater node, for example) and edge nodes and to each mobile station. A routing node, receiving data including the IP address of a mobile station, carries out routing of the data in accordance with routing information. The edge node that receives the data routed by the routing node, transmits the data to the mobile station corresponding to the IP address of the mobile station added to the data. The IP addresses are also applicable to delivering data to users of the same group, or carrying out control like handover.

摘要： To provide an address dynamic assignment system, a relay apparatus, a location manager, an address management apparatus and an address dynamic assignment method for dynamically assigning terminal identification address information for identifying a mobile node without putting load on a radio section by reducing a message amount in the radio section. An MN 1 sends an LR including IPha information to an AR 2. An address acquisition necessity determination portion 21 of the AR2 determines whether or not there is a need to acquire the IPha information to be assigned to the MN 1 based on the IPha information included in the LR. An address acquisition proxy portion 22 of the AR2 acquires the IPha information. A post-address-acquisition location registration portion 23 sends an LU including the acquired IPha information to an LM 4. An assigned address notification portion 24 sends back an LRAck including the acquired IPha information to the MN 1.

摘要： A communication system 32 is provided with access routers 14, a location information management server 20, and a route optimization server 18. The route optimization server 18 receives a BU message from a Mobile-IP terminal 12A and receives location information of a connected access router 14A from the location information management server 20. Then the route optimization server 18 transmits the BU message to the connected access router 14A, based on the received location information of the connected access router 14A, whereby the connected access router 14A to which the communication terminal 12 is connected is notified of route optimization information. This permits the connected access router 14A to relay a packet transmitted and received between the Mobile-IP terminal 12A and the communication terminal 12, through an optimal route.

摘要： The problems of an additional load to an AR having the function of transferring a packet, a BR functioning as a border relay device, and an address management server, a packet loss due to an unnecessary inquiry to the management server, an increasing delay of a packet transfer, etc. can be reduced. According to the address identification information for identification of the type of an address, routers determine to which type the address assigned to a given packet belongs, a terminal identification address for identification of a source terminal and a destination terminal, a packet transfer address for transfer of the packet to another router, or an address requiring no address conversion. Thus, an address conversion network connected to an external IP network can be realized, an increased load by an inquiry about an erroneous address, etc. and a packet loss and delay due to an unnecessary inquiry can be reduced.

摘要： A short cell multiplexing is provided for chiefly transmitting data shorter than the payload of a standard ATM cell (basically the data of less than 48 bytes, but the data more than 48 bytes can be allowed). A standard ATM cell assembler 1 converts various forms of input information into short cells, places the short cells in standard ATM cells efficiently considering their information length, and output them to a B/ISDN network 7. The standard ATM cell disassembler 2 disassembles the standard ATM cells, which are assembled by the standard ATM cell assembler 1 and is input through the B-ISDN network 7, into short cells, converts the short cells into those with the original input information forms, and outputs them to channels. The configuration makes it possible for the short cell ATM cell multiplexing to improve channel efficiency with small delay, and matching to the standard ATM system.
