Can anyone tell, In what basis n/w Half/Full rate TCH to MS in IMMEDIATE ASSIGNMENT COMMAND
Regards,
selva nhi,
it is only based on what the BSC decides to do. and the BSC itself bases its decision on the outputs from the TCH allocation algorithm.
Usually, under a specific load threshol, the TCH is allocated in FR. Above this threhsold, the TCH is allocated in HR.
The load = the TCH load in that cell.regards
pixHi Pix,
What is the need of Network setting “IMSI attach flag” (0 or 1) in system information.
I know if the IMSI attach flag is set to 1, MS will do IMSI attach or else It will do location update.
But what condition Network will set it to 1 or 0.
Thanks & Regards,
selva nhi pix,other than quality wat disadvantage we have with half rate?
There is no disadvantage in using hald rate…infact if you activate AMR in the network than half rate call will as capable as Mon-AMR full rate.
hi,
impacts other than voice quality:
– increase of traffic on AterMux and A interfaces
– increase of traffic load in the BSC (might impact the BSC dimensioning)
– need to tune HR and AMR-R thresholds
– need to buy HR licenses in order to declare TRXs as HR-capable (same goes for AMR-HR)Those are not disadvantages… just “constraints”.
Cheers,
pix
