20.500.12556/DKUM-39436 UPORABA TEHNOLOGIJE VOIP NA MOBILNIH NAPRAVAH SYMBIAN VOIP TEHNOLOGY ON SYMBIAN MOBILE PHONES V sklopu diplomskega dela smo razvili aplikacijo, katere cilj je nižanje stroškov klicev s pomočjo tehnologije VoIP. Ta za komunikacijo uporablja protokol IP in zaobide potrebo po navadnih in dražjih GSM klicih. V času načrtovanja aplikacije je bilo okolje Symbian najbolj razširjena mobilna platforma za dovolj zmogljive, t.i. »pametne telefone«, ki lahko poganjajo VoIP aplikacije. Izbrali smo skupek knjižnic, poimenovanih Qt, ki omogočajo enostavno prenosljivost na druge platforme. Podrobno je opisan postopek izbire orodij in razvoja aplikacije, ki vsebuje načrtovanje, gradnjo, namestitev in testiranje na mobilni napravi. V zaključku so na realnih podatkih mobilnih operaterjev izračunani stroški VoIP klicev, ki so znatno nižji od navadne tehnologije GSM. Predstavljena so tudi izhodišča za optimizacijo in nadgradnjo obstoječe rešitve, ki bi omogočila v celoti izkoristiti potencial tehnologije VoIP. The purpose of this B.Sc. diploma is to present the development of an application aiming to reduce the call costs using VoIP technology. It uses the IP protocol for communication and thus circumvents the need for standard and more expensive GSM calls. At the time of the planning, the Symbian environment had been the most widespread mobile platform for the more advanced, so called »smart phones«, which are able to run VoIP applications. We have chosen a framework called Qt, which also enables easier transfer to other platforms. The dissertation provides a detailed description of the procedure of tool-selection and application development, which includes planning, building, installing and testing on the mobile device. In the conclusion we have provided the calculations of the costs of VoIP calls, based on real data obtained from mobile service providers. The VoIP costs are substantially lower than those of standard GSM technology. Apart from the analysis we have also added some ideas for optimization and upgrade of the current solution, which put to light the untapped potential of the VoIP technology. programska oprema prenos govora Tehnologija VoIP software voice transfer VoIP technology true true false [T.
