Mobile Radio Network. Contents. Introduction and background Literature review: Architecture of Mobile Radio Access Networks State of the art in management of mobile networks as defined by 3GPP Performance management data Functionality scenarios in UTRAN Methods of the practical study
How to enhance the productivity of the UTRAN performance management investigations?
param or software?
Calculated most often from performance counters to relative %-values
Achieved by using a reporting tool that collects the needed counters from the OSS measurement database and calculates the KPI values based on the counters. By manual post-processing the data, the graphical output
2. Find measurement periods where there is a dip in performance:
Call setup performance: at 11 the CSSR KPI has had poor values. The phenomenon has been partly ongoing during the next hour
Retainability: high drop call ratio at 16. Counter diagram verifies that the drop in CCSR is due to high number of RAB active failures.Results (II/IX): Example on current PM and FM process (1/3)
5. Gather the system logs for those network elements that are main contributors of the RNC performance dip.
6. Analyse the detailed data.
=> no general guidance can be set for the analysis itself.
