Any timer in MME to tweak to improve SRVCC preparation success rate to 2G?
One layer of 3G is being switched, another is to be done very shortly.
So 2G would be the main legacy layer now.
Any case study, if can be shared, would be very helpful.
Not much experience in this area, but have you tried to enable flash fallback to 2G (if vendor is Huawei)?
That improves success rate and handover time if 2G is fully overlapped.
Is it RAN feature or Core feature?
Mostly RAN but my need some configuration at MME.
How much is your Handover Interruption time from LTE to 3G/2G?
We are checking through KPIs and counters.
One action taken on delete and recreate gerancell relations at node end.
Drive test yet not planned, we are checking improvement through parameter tuning, lac splitting etc.
Any core timer to tweak?
I thik its RIM in Ericsson. RAN Information Management.
I thought so, RIM is already enabled.
It’s tough to check RIM Performance. Counter also peg only once when association creates.
Also it’s for CSFB only.
