16、Technical Committee Speech and multimedia Transmission Quality (STQ). Introduction The present document defines QoS parameters and the corresponding measurement and evaluation procedures as a supplement to the ones defined in TS 102 250-2 i.1. For the QoS parameters proposed in this document the ter
17、m Fixed Data Transfer Time QoS (FDTT-QoS) parameters is used. The main purpose of proposing the concept of FDTT-QoS parameters is to fulfil the common request for many QoS measurements to have a limited and regular run time for individual measurement tasks. Due to the wide range of uplink and downli
18、nk throughput in modern mobile communication networks, limited and regular run times cannot be provided when having e.g. fixed object (file) sizes for the measurements. Limited runtime is required to ensure that all measurement tasks are finished before the data window ends, where the term data wind
19、ow is used to define the time period from the start of one data session (containing one or several measurement tasks) to the start of the next data session and the time duration of the data window is set to a constant value. For example a data session consists of 3 measurement tasks - FTP DL, FTP UL
20、 and HTTP. Limited time for each task (e.g. 30 s) ensures, that the data session will be completed in 3 30 s and all tasks (FTP DL, FTP UL and HTTP) will be performed. Regular run time is required to ensure that a minimum percentage of the data window is used for measurements. This document describe
21、s how the requirement of regular and limited runtime can be achieved by using these FDTT-QoS parameters for data measurements, especially for FTP and HTTP data transfers. Advantages of the FDTT-QoS parameters and measurement method: Low variation between minimum and maximum measurement time. This is
22、 important if measurements are done in regular intervals. Required measurement time for slow connections is reduced while maintaining the accuracy for high speed connections. Better distribution of measurements in drive tests. Using FDTT-QoS measurements, the same number of tasks or job executions p
23、er time interval can be achieved regardless of the network access technology. Better resource utilization. To determine the throughput a certain time is required as several processes in the network are time dependent. Thus, a time based measurement concept for throughput measurements has the advanta
24、ge of providing reliable measurement values for fast connections while not wasting network capacity for slow connections.
