Application of drive test for QoS evaluation in 3G wireless networks

A full QoS evaluation for a newly-built network should be performed so that engineers and operators can discover and solve the problems before the network goes into operation. Because data services are becoming dominate, more care about QoS evaluation for them should be taken. This paper presents application of drive test for QoS measurements. The measurement schemes of each QoS parameter like throughput, delay, delay variation, and data loss, etc. are described. These schemes proposed in this paper are effective and can be put into practice.
