About this documentAbout this document

Purpose

This document specifies the Alcatel-Lucent recommended performance metrics toevaluate the CDMA voice services offered by the Flexent /AUTOPLEX System.

The Watchmark Prospect for Lucent User Defined Calculations (UDCs) are also included

in this document.

Reason for revision

This IP is continually updated. Check this "Reason for revision" section for the mostcurrent changes. This IP will be re-published only on the web for important and/or substantial updates.

There are no technical changes for Release 37.

To Obtain Technical Support, Documentation, and Training or Submit Feedback

The Online Customer Support (OLCS) web site, http://support.alcatel-lucent.com , provides access to technical support, related documentation, related training, andfeedback tools. The site also provides account registration for new users.

Service provider perspective

Operators of Alcatel-Lucent wireless systems use performance and capacity metrics tohelp evaluate the performance and engineer the system. The metrics recommended byAlcatel-Lucent to monitor performance of a Flexent CDMA system are: Established Call Rates Dropped Call Rates RF Failure Rates Call Delivery Metrics

Metrics recommended by Alcatel-Lucent to help engineer and grow a Flexent CDMAsystem are: Origination/termination Channel Element Overflow Rate Handoff Blocking Rate Primary Channel Element Usage Rate Channel Element Minutes of Use Handoffs Denied due to Power Control Overload

Metrics recommended by Alcatel-Lucent to help engineer CDMA carriers are: Origination and Termination Overflow for Carriers Traffic Code Channel Usage for Carriers Primary Traffic CE Usage for Carriers

Metrics recommended by Alcatel-Lucent to monitor the performance of CDMA carriersare: Percent overload duration for carriers RF failure rates for carriers

Metrics used to evaluate total system (an ECP together with its DCSs and cells) performance and to help engineer the growth of the system: System access denial rate (call blocking rate) System dropped call rate System average call holding time

Metrics used to assess the call delivery (paging strategy) performance:

Home/Local Termination Call Delivery Rate Inter-MSC Call Delivery Metric
