Dear experts
I need your help please to share information and experience about having 2G CSSR degradation after old site Swapped to eGBTS site?
For troubleshooting we need more information:
1. Which component of CSSR degraded? (typically there are four components: Immediate Assignment Success Rate, SDCCH Congestion Rate, SDCCH Drop Rate and TCH Assignment Success Rate)
2. Did you confirm if the TRX capacity, frequency plan and MAIO plan exactly the same as before?
I need your kind help for below issue
One thing which very complex for me is there is no any TCH or SDCCH interference but DW and UL quality degraded after BTS changed to eGBTS.
