Limiting the number of users on an LTE Cell
Hey Huawei gurus,
Wondering if one of you could help me with a small problem I have. I want to limit the number of users in connected mode on a cell that gets slaughtered during the day (ave 800 connected users in business hours) - throughput per user is roughly zero. Scheduler has crapped itself, probably an RRC storm as well.
Now, I want to reduce the number of users on a cell level (not MaxSyncUserNumPerBbi)
Can't see anything in Hedex that shows me how. Have thought about using access class barring but need to know more about how it's set up in my network before I try.
Is there a way of setting a hard limit on the number of connected mode users in a cell?
Thanks

hi man,
if you hard limit ,what would be users feeling with that denial ? if you expect it will search another neighbor cell then you should go in that direction dont you think ?
what about the algorythms for load balancing ? InterFreqMlbThd ? inter freq, intrafreq , etc ??

Better than what we have now:

That blue line - the cell throughput. Collapses after the number of users reaches a critical threshold. And then you have worst of all worlds - lots of users, no one getting anything. We'll put up with bad KPIs to improve user experience.
It's only a temporary fix - we're working on an actual solution as well...

MLB gives good results in case Dual Band, in the below case LTE800/LTE1800:

Re: Limiting the number of users on an LTE Cell
what is the number of users after which user throughput drops ? can you also mention your spectrum bandwidth and user experience before the drop ?
