Need answers to few questions???

[trainee10]

Hello everyone, i desperately need answers to following question; i will appreciate your time and patience for this...

1) what is retainability? and how to minimize it?
2) what is access failures and how to minimize it?
3) what is accessibility?and how to minimize it?
4) How do we minimize drop calls? or what are parameters we have to tune to minimize drop calls and access failures?
5)what are the parameters involve in IRAT procedure?
6) what is single site verification?
7) parameters for cell selection and reselection?
8) difference between too many serving cells and pilot pollution?
9) how to increase data throughput for hsdpa and what are the parameters involve in HSDPA improvement?
10) if there are too many servers for UE then UE camp on which server and why?


Once again i request all the senior engineers or optimizers to answers the above questions and i thank all of them for their time.......

awaiting answersss.....

5)what are the parameters involve in IRAT procedure?

here is the xml script of E******* that creates CELL12 and CELL22 IRAT neighbour in RNC of RNCNAME.

Just simple question ..Which Vendor youare aking about ??

[moslyi0891]

I will answer in General (You have to specify which vendor anyways:
1) what is retainability? and how to minimize it?
Retainability is the : accesiblity and RAB Drop totally togather ..this is pro indicator how UU is :: RRC Connection Setup Drop and RAB Drop and RRC Connection had been established and Drop happens without begining of RAB establishment
The solution is to minmize RRC Access Drop and RAB Drop and

2) what is access failures and how to minimize it?
You have to specify is it RRC Access Failure or RAB access failure
incase RRC Access failure you have to improve the RACH performance by :
A-maiximize the the UE transmitted power : MAX-Allowed-UL-TX-Power
-b-increase the power quickly Power offsets 1
-C-increase the No of Pre-amble sent again Cycle : Pre-amble -Retarnsmit Max
-D-Increase the No of Preamble Cycles
-E-Increase the No of RRC Connection Request Retry

This answer is wear somewhat :eek:
Those questions are interveiw questions and they need practical short answer ,,meaning what are the most tunned parameters in this case ......Window size,,,,pla pla pla not full details:L
small peices is required :rolleyes:

so would you tell us what are the most tuned parameters for I-RAT Handover ??
