Smalbands, integrert applikasjonsnettverk for telekommunikasjon

The invention relates to a narrow band integrated application network with multifunctionality, for instance for PSTN, ISDN, NMT, GSM and DECT. The network has a logical and physical structure including functional subnetworks for managing different functions with defined interfaces between them. The network can be divided into a mobility network, a service network, a switching network and a connection network, which are technically independent. The invention especially supports personal mobility by means of personal number and terminal mobility.
