Dear experts,
I have a query regarding CORE migration, where H***** has been replaced by E*******. Immediately after migration, there was increase seen in TCH / SDCCH drops. It was assumed initially...

Please explain the detail, so we get to know before downloading it.

Definitely, I used 'LAC' as a very basic example, just for the sake of easy understanding.
But you raised a valid point.

Regarding the second query, FDD and TDD are two different kinds of domains and separate TACs are recommended in one cluster / MME. This is usually the Design requirement of operators and I believe...

TAC = Tracking Area Code, broadcast in SIB1 message for each eNodeB.

For simple clarification, it's pretty similar to the LAC in GSM.

I am not so sure about this N200 HO failure thing but I remember an E******* site that had frequent T200 failures & call drops.

1. The cell was showing excessive 'suddenly lost connection' drops....

Please check the post by Imran Rafique below. Check its point 1 & 3. I think you may get the answer, you need to check if the mentioned features are enabled at BSC level or not.

Addition of another CCCH?
What is the name of timers for first & second page response time?

Dear Imran,
Feature no 3 came in which BSC version of E******* ?

Well, it depends on the band. Go for those which are interference free. The BCCH is clean usually, so I have always preferred the SDCCHs on that. SDCCH can also be put on hopping, & I have heard of...

I have always found that cells with high paging congestion turns out to be cells with the huge configuration of TRXs. Can you explain how please? Thanks !

An example is about a cell with 4 TRXs.

1 BCCH TRX, 3 TCH TRX

We could define max 6 SDCCHs (2 from the BCCH and the 6 in the TCH TRXs). 8 were max, it is 25 % of the total capacity of these 4...

Dear Haider,
I do not have a document but you can judge like this:

One can define 25% of the TRX capacity of a channel group. In E*******, there is a parameter called MAXNOOFSDCCH which has to be...

Ok, so you are having high drops. Are the drops due to Low SS, excessive TA? I think the cell is overshooting & you may have to down tilt it. Is it a rural cell?

So it means your cell is doing a lot of location updates. You need to check the following:

1. Check the MRR stats to see if the cell is serving far away (TA samples). Down tilt the cell if you...

Most of the times, this KPI is owned by the CN team. They are the ones suggesting LAC dimensions based on the traffic load. RF does the cell level part mostly.

Try changing the parameter MFRMS, you may have to reduce it. Its normally at 4 & 3.
Check the SDCCH traffic type on the cell (assignment, location update etc.)

Thanx ... But its giving me a license error !!!

Found it ... Thanx.
