Abstract

In the UMTS network, UTRAN, PS core, CS core, and UMTS QoS architecture form a framework for QoS measurements, which have to be performed to ensure that a UMTS subscriber is served properly. The true picture of QoS is perceived by acquisition signaling and user-plane data from the network interfaces, and performing analysis for those. From an operator’s perspective, the QoS consists of several factors, each of which brings different kinds of measuring requirements for the operator when developing and operating the UMTS network. Protocol decoding, signaling procedure analysis, and tracing of the subscriber dedicated protocol messages are needed for testing, verifying, and troubleshooting the UMTS network in live or laboratory environments. The traffic and capacity-measurement challenges rely on the interfaces where the user data is transferred over a packet or a circuit switched domain where the most important key performance indicators (KPI) are related to delay and throughput. KPI values, generated by statistical measurements, may be used to express the service availability or the behavior of the radio access or core network domain. Moreover, sophisticated protocol analyzers and network probes are the basic tools for acquisition, decoding, and analyzing the protocol layers, and they form the base for more intelligent post-processing or real-time applications.
