The disclosed communication node has a function for recognizing one communication node on the first network as one of constituent elements in own communication node, and a function for disclosing an own configuration information regarding the constituent elements as recognized above, to another communication node on the second network. Also, the disclosed communication terminal has a function for disclosing functions in the own communication terminal as Sub Units in an AV/C (Audio/Visual Control) protocol executed on an IEEE 1394 bus, and a function for receiving at least a part of information regarding Sub Units existing in the communication node on the second network with which it is communicating. Together, these communication node and communication terminal make it possible to transmit various information transferred on the IEEE 1394 bus, to the radio node that is connected by the radio interface, and it becomes possible to execute the data communications as if the connection to the IEEE 1394 bus is made by the radio interface.
摘要:
A mobile IP communication scheme in which the mobile computer can be operated using the mobile communication protocol such as Mobile IP even in the case where the home network is operated by the dynamic address allocation protocol such as DHCP is disclosed. The current location registration message to be transmitted by the mobile computer from the visited site to the mobile computer management device contains an information indicating that the dynamic address allocation has been received at the home network and an information capable of identifying the mobile computer, and the mobile computer management device carries out exchanges with the dynamic address management server on behalf of the mobile computer, so that the mobile computer which has received the dynamic address allocation at the home network can be operated at the visited site by using the mobile communication protocol.

A mobile supporting router device for realizing the handoff control associated with the moving in high speed is forms by at least one first interface connected with radio base stations, each capable of accommodating at least one mobile terminal; at least one second interface connected with a wire network; an information exchanging unit for exchanging a routing protocol on a network layer, through the second interface; a memory unit for storing information regarding a routing on the network layer based on the routing protocol exchanged by the information exchanging unit; a transfer unit for transferring datagram through the first interface according to the information regarding the routing on the network layer stored in the memory unit; a moving detection unit for detecting a moving of the mobile terminal among the radio base stations; and an information updating unit for updating the information regarding the routing on the network layer stored in the memory unit when the moving of the mobile terminal is detected by the moving detection unit.
摘要:
A method of back-tracking in a computer processing in which the programmer can be provided with a number of different types of the back-track controlling, from which a suitable one can freely be selected in accordance with the need of the programmer. In this method, a flag is provided in each choice point, for indicating a type of back-track controlling, and a stacking which contains an address of a choice point specified as a present choice point by a present choice point register and an address of a preceding choice point which is immediately preceding the present choice point is utilized in changing indication of the flag.
摘要:
In a document processing apparatus including a heading word dictionary (7), a heading extractor (6), a heading rule dictionary (8a), a heading decision section (8), a document architecture rule dictionary (9a), a document architecture decision section (9) for deciding a logical document architecture, the apparatus further comprising a rule application decision section (12) and a candidate selection indication section (14) to allow the operator to select any desired document architecture, when the document architecture decision section (9) decides plural document architecture candidates in accordance with document architecture rules, thus improving the operability. Further, the past rule application record information (priority order) is stored and updated so as to provide a learning function for providing a better operability.
