Kurs Titel:

GSM and (E)GPRS Troubleshooting of Radio Netw. with Life Netw. Analysis

   

Bestell-Nr.:

TA-TC 6060

   

Dauer:

2 days / web session 2x4 hours

   

Zielgruppe:

Personnel from performance monitoring and optimization department as well as BSS system specialists and field engineers.

   

Zielsetzung:

Based on OSS performance data of the customer�s own network, troubleshooting of the worst cells, BTSs and sites by call phase and root cause drill down will done. Additionally a network audit will be given analyzing the problems dominating within the BSC area selected by the customer. This workshop is considered as additional module to the course "GSM and (E)GPRS Optimization of Radio Networks". Optimization examples will be discussed on the basis of OSS data of the customer�s network, which are summarized as report. TECHCOM will analyze one BSC area on the basis of the vendor specific OSS statistic. Air interface performance (RxLev, RxQual, frame erasure rate, C/I, MCSs, RLC BLER and LLC frame erasure rate) and traffic distribution (SDCCH and TCH Erlang, number of TBFs, throughput) will be analyzed with a geographical accuracy better than cell level.
