Abstract

S dolaskom mreža idućih generacija, prednosti definitivno nadmašuju nedostatke. S novim mrežama dolaze i veće brzine prijenosa te je potrebno zadovoljavanje svih zahtjeva vezanih uz mobilnost. Jedna od funkcija mobilnosti je prebacivanje poziva između ćelija. Kada korisnik prelazi između ćelija, bitno je da pružatelj usluga može omogućiti besprijekorno prebacivanje sesija u tijeku (govor, podatkovni promet) u novu ćeliju. Kod LTE-a (engl. Long Term Evolution) dolazi i do prebacivanja prema drugim tehnologijama što stvara dodatne zahtjeve za kvalitetu usluge. U ovom radu analizirane su i opisane glavne procedure prebacivanja poziva u LTE-u. Grafički su prikazane odgovarajućim UML (engl. Unified Modelling Language) dijagramima te objašnjene pomoću odredbi koje su uvele 3GPP izdanja.

Abstract (english)

With the arrival of next generation networks, the pros definitely outweigh the cons. New and improved networks also come with faster speeds and their mobility specific demands need to be met. Handovers are a function of mobility management. When a user is switching cells, it's important that the network operator can provide seamless handover of all active sessions (voice, data transfer) into the new cell. With LTE, handover to other technology networks have to be included, which creates extra demands for quality of service. This final paper analyses and describes the main procedures concerning handovers in LTE. They are displayed via appropriate UML diagrams and explained in context to the 3GPP editions.
