Zaključak
Svijet
komunikacijskih usluga je promijenjen zahvaljujući iznimno
brzom razvoju Interneta i drugih podatkovnih usluga te
zahvaljujući mobilnim uslugama. Postojeće arhitekture mreža
ne mogu zadovoljiti rastuće zahtjeve i potrebe krajnjih
korisnika. Za to je potrebna otvorenija i prilagodljivija
arhitektura mreže koja se može postići migracijom iz više
jedno-uslužnih u jednu više-uslužnu mrežu. ENGINE model
Ericssonovo je rješenje za mreže nove generacije. On omogućava
prijelaz u novu generaciju više-uslužnih komunikacijskih mreža
u kojima mogu biti objedinjene podatkovne i govorne usluge,
fiksni i mobilni pristup.
