hi guys ………
what are the cons if MSC location update timer value is less than BSC location update timer value.
when we get sim registeration failed issue26th February 2008 at 04:54 #51205BilalGuest
By MSC location update timer do you mean Detach Timer? If yes then MSC will explicitly detach the MS before it makes a periodic location update as set by T3212 timer in BSC. MS wont be able to receive any paging till it makes a LU (periodic or LAC change).28th May 2008 at 16:06 #51206salem GGuest
im asking if any one tell me whats the mathmatical models which i can use them for the location management of movement & time and distance location update , if i want to run matlab software>4th June 2008 at 10:04 #51207DebasishGuest
My question is why timer T3212 value is set in BSC? Why MSC does not controll timer T3212?4th June 2008 at 10:08 #51208pixGuest
this is a radio parameter that is transmitted in the BCCH. and changing this timer can have a big impact on the radio load. for this reason, the timer is set at BSS level, not NSS.
with all due respect : why do you question 3GPP implementation ?
the point of GSM engineering is to go along with the 3GPP rules, otherwise you’ll spend too much time complaining and little time actually optimizing :))7th June 2008 at 05:42 #51209DebasishGuest
Thanks PIX.7th June 2008 at 07:05 #51210DebasishGuest
Thanx pix,it is just a query.
One more query.
What is GSM recommendation to keep Implicit detach timer value with respect to T3212?7th June 2008 at 08:35 #51211pixGuest
as bilal said below, the MSC implicit detach timer shall be longer than the T3212. Something like double i’d say.
