Quality of heterogeneous mobile data services: capabilities and end-user achievements

Abstract

Then analyzing quality characteristics of different segments of the telecommunication network it was noticed that bandwidth, delay of packets and reliability of the last-mile of the end-users are worse and less stable than in the core network of the system It means that the bottleneck of QoS of end-users is in the radio access of the last-mile therefore different users receive different QoS The goal of this paper is to investigate possibilities of end-users to receive service quality, defined by the network operator It is also important to analyze dependency of the received data throughput of the end-user on the distance to the base station and time in the fixed position It was proved theoretically and practically that the downlink throughput, achieved by the end-user depends very much on the location of the user in the coverage area and time.

Analizuojant mobiliojo ryšio tinklų kokybės charakteristikas pastebėta, kad vartotojo linijos pralaidumas ir bendras patikimumas nėra vienodi ir keičiasi priklausomai nuo vartotojo buvimo vietos ir laiko. Vartotojams realiai teikiamos skirtingos kokybės paslaugos. Šio darbo tikslas – atkreipti dėmesį į esamą problemą, atskleisti jos priežastis ir pateikti pavyzdžių, kaip kinta galutiniam vartotojui teikiamų paslaugų kokybė. Parodyta, kad galutinio vartotojo pasiekiama duomenų perdavimo sparta priklauso nuo vartotojo vietos bazinės stoties aprėpties zonoje, nuo tinklo apkrovos ir nuo laiko.
