Optimum traffic conditions can be achieved in the Public Land Mobile Network (PLMN) thanks to an increasingly sophisticated range of variations in network design and traffic routing. This involves the increased intermeshing of the network nodes and thus a greater planning effort. Careful, future-oriented planning makes it possible, in the majority of cases, to avoid traffic bottlenecks and overload situations, even in the face of major traffic fluctuations.
Traffic data acquisition is therefore of decisive importance for the telecommunications carriers with respect to:
•Traffic Handling
Traffic bottlenecks can be detected as early as possible.
A consistently high quality of service can be ensured, resulting from the grade of service, call processing performance and transmission quality.
•Traffic Forecasting
Network nodes can be composed for the long-term, demand-oriented expansion of the networks.
Contrary to the systems of older technology, the UltraWAVE system does not require any special equipment for traffic data acquisition. A broad range of intra-system functions is available for the tasks at hand. These functions collect and process traffic data from all parts of the network nodes and trunk groups. For instance, the call processing programs include traffic data registration and specific programs record traffic measurement data.
This chapter describes how to use the statistics archive to monitor and analyze the system traffic profiles. The organized statistics can be displayed in both tables and graphics, and are available for call records, service provisioning and network loading. The EMS server collects the statistics data from all system entities and refreshes the statistics report every 15 minutes. The EMS database stores seven day's statistics profiles.
The PPS daily report provides a daily report about the PPS service including organized statistics information of account, recharge card and call.
The MSC statistics provides call measurement on five bases: Service, Trunk Group, Erlang and BHCA.
The AAS provides recharge and announcement measurements.
