Coverage impact for data traffic profiling in WCDMA networks

Abstract

Nowadays UTRAN is a key data carrier in mobile communications. Serving a majority of customers and processing an enormous traffic quantity it must ensure a sufficient quality of service (QoS) level. QoS reflects how satisfied the users are with the received services. The goal of this research is to ascertain a benefit of QoS for differently profiled UEs. This study investigates HSPA service dependence on uneven radio network conditions for separate users. Users belong to background traffic class and use a data service as other conventional network users. To draw an impact of radio conditions variation, radio signal strength was decreased gradually for a user with a higher priority. The research is performed on heavy loaded commercial network WCDMA cells. The performance of the user experience is analyzed by the metrics | data rate and channel quality, which are provided graphically and reflect the user received gain based on radio environment changes. Customers' prioritization drawbacks in cellular networks are introduced in study also.
