EUTRAN Neighboring on eNodeB DLEARFCN Update Process

I'm sharing the process to change the DLEARFCN from all the eNodeB of the network, this is made with the object of increase the carrier bandwidth from 10MHz to 15MHz or 20MHz.

The next is the script execution process to update the DLEARFCN on every eNodeB:

- RMV EUTRANINTRAFREQNCELL (To remove eNodeB neighboring, cause I'll change the DLEARFCN from this relationship).
- MOD CELL (To update the DLEARFCN on every eNodeB cell).
- MOD EUTRANEXTERNALCELL (To update the DLEARFCN from eNodeB external cells).
- ADD EUTRANINTRAFREQNCELL (To add new eNodeB neighboring with DLEARFCN updated).
- MOD ULTECELL (On the RNC to update the neighboring relationship from UMTS to LTE).

This should be done on every eNodeB, one by one on WebLMT; on the execution process, there will be a discontinuity with the eNodeB that are not updated yet which will affect the user experience, so this work should be executed fast and it's recommended to modify it at night.I hope it can be helpful.

Best Regards!
