Abstract
Streaming services over UMTS are expected to be one of the most demanding services in future, with streaming users can display the multimedia file before its transfer is completed. This work is aimed to verify the performance of multimedia streaming service over Nokia WCDMA test network from end-user perspectives. The measurements are carried out over streaming and interactive QoS class in stationary and mobile situation, the mobility measurements include streaming during soft handover. The streaming QoS is verified through a set of Key Performance Indicators (KPIs). These includes call setup and call quality KPIs. This work shows that the performance of multimedia streaming was significantly improved after modification to the packet core network functionalities. After the modification the streaming performance over 64/64 and 64/128 Real Time (RT) bearers was good and it was not totally satisfactory over 64/256 UL/DL RT bearer. The streaming performance over Non Real Time (NRT) bearer in unloaded cell was slightly better than streaming over RT bearers. This work provides a verification of wireless streaming performance over streaming class before the commercial launch of the service. It also provides a benchmark of video streaming performance over real time and non real time bearers. This work can be used as an input to obtain maximum streaming service utilizationDescription
