NETWORK STRUCTURE REALIZING PART OF RADIO ATM SYSTEM AND METHOD FOR EXECUTING HAND-OVER BETWEEN SWITCHES IN THE NETWORK STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a network structure suitable for extending radio channel of an ATM network to execute hand-over between switches. ;SOLUTION: In the network structure to realize a radio channel extension of an ATM network, only part of a switch of the ATM network is provided with a function required to support a radio terminal equipment. Between the radio and specific switch, individual connection to distribute control and management information is provided. The radio-specific switch and the individual connection inbetween forms a parallel tree PNNI node structure relating to th rest of the ATM network and the radio-specific switch belongs to the node structure of a regular ATM network in addition to the PNNI node structure. In the structure above, addition being a requirement by the support of a radio terminal equipment using the PNNI protocol is very small.;COPYRIGHT: (C)1998,JPO
