steps to modify BCCH
Hi all, I need to change the BCCH of a cell.
I've tried the following MML commands but they failed:
DEA GTRX: IDTYPE=BYID, TRXID=XXX;
MOD GTRX: IDTYPE=BYID, TRXID=XXX, FREQ=YYY;
ACT GTRX: IDTYPE=BYID, TRXID=XXX;
Which secuence of MML should I place? Should I deactivade the cell the first?
Thanks!

Hi:
The easiest way is modify the BCCH is using CME, if you modify it using commands you will have to manually modify all the neighbor relations and it can lead to errors.
CME will automatically made the changes for you.

Thanks Javier, the problem is that I have not privileges to make changes via U2000/CME.
Every change I need to make should be made via MML script, sent and run by the O&M dep.

Hi, then you really have a problem, because if you just do it manually the handovers will not work, modify all the relations 2g<>2g, 2g<>3g, 4g>2g...manually can be really difficult, via CMe can be done in lets say 10 minutes, via MML hours.

Hi
No need to deactive TRX or Cell. You just need to:
- Add new BCCH to Cell by command: ADD GCELLFREQ
- Modify BCCH TRX by command: MOD GTRX
- Update neighbour information
It takes only 5 minutes

Thanks guys!
I'm gonna try the following:
DEA GCELL
RMV G2GNCELL (where my cell is the target)
ADD GCELLFREQ
MOD GTRX
RMV GCELLFREQ
ACT GCELL
ADD G2GNCELL (previously removed)
MOD externals
I'll share the results
