1 Introduction !his description contains flocharts for the main performance events. &t should be noted that the events presented are merely a subset of all 'NC events. Event descriptions for all 'NC events# and information about 'NC5specific events functionality and parameters is included in 6eneral 3erformance Event 7andling. 7andling .

Main Symbols

All flocharts are dran from an 'NC perspective# trying to reflect the actual 'NC implementation# but not necessarily covering complete procedures.

2 Events !his section describes the performance events flocharts.

!he system resource utiliDation measure is based in the C'NC and is recorded as one periodic performance event report per cell. ,ultiple cell reporting is specified by the operator through user5defined 63E7 scanners. ?hen the event is activated# &N!E'NA()*+*!E,)!&(&1A!&-N &N!E'NA()*+*!E,)!&(&1A!&-N is issued every time the timer e@pires. &f the 7*# E( or ,B,* is not activated in the cell# the corresponding 7*# E( and ,B,* respective resources are reported as uest or failure at Cell pdate :see 4igure ; ; 4ailure at *ignalling Connection Establishment :see 4igure F; F; Abnormal ''C Connection 'elease or *ignalling Connection 'elease :see 4igure G; G; *ending of 'AB Assignment 'esponse indicating failure to setup or modify 'ABs :see 4igure H; H;
