hi, what is the recommended value of AGBLK in the network. is there any preferred value. we are using alcatel system.22nd August 2007 at 08:36 #48960pixGuest
it all depends on your PCH load.. but you can be safe by putting dynamic AGCH everywhere :
BS_AG_BLKS_RES = 1 (only 1 block reserved statically)
AG_PREMPT_PCH = 1 (enable –> the AGCH blocks will preempt the PCH blcoks if more than 1 AGCH block are needed)23rd August 2007 at 13:26 #48961ADGuest
A person from alcatel support in my country told me that alcatel equipment doesnot support dynamic resource allocation for control channels. is he right? You earlier said that by making agblk-res=0, the resources are allocated dynamically (if i remember correctly).
Does that person mean that we cannot set agblk-res = 0 in alcatel network???
kindly comment.23rd August 2007 at 19:41 #48962pixGuest
Which country are you in ?? I can’t believe an Alcatel expert told you this. You must have misunderstood. This feature is availble since B7 if my memory is correct.
It is possible to put AGBLK RES = 0, and that will automatically set AG PREMPT PCH = 1 (enable). I’ve done it myself on many cells. no problem.

some body told me that by playing with AGBLK and MFRAM parameters we can improve paging suc rate.it is right can any body explaine me…..how?????25th August 2007 at 04:22 #48964asoGuest
you can improve paging success rate by this parameter but you have to study paging load for example I face this kind of problem when i try to improve paging after change MFRAMES i found there is paging overload in Abis interface and when i increase this parameter (MFRAMES) from 2 to 4 and AGBLK2.
again check if you have already load in Abis or not if you have you need to put MFRAMES to low value and if you can as pix mentioned you can put AGBLK to 0 but be careful you have to check you donot active CBCH and SI7&827th August 2007 at 07:38 #48965MeGuest
hi , i was looking at the Alcatel parameter dictionary and i found that the recommended value for alcatel is 1, or 4 for non-combined BCCH :S27th August 2007 at 10:31 #48966Da ArchitectGuest
Recomended BS_AG_BLKS_RES = 1 for Combined BCCH with SDCCH. while it is recomended to have BS_AG_BLKS_RES = 4 in case non-combined, but take into consideration the PCH Load in case BS_AG_BLKS_RES = 4.27th August 2007 at 10:36 #48967Da ArchitectGuest
in alcatel timer T3113 (check with NSS)has a value = 28. I know that this T3113 = 28 is in hexadecimal and must be converted to decimal so that it becomes T3113 = 40.
Now i want to know the step for this value.
i think the step is 0.1 => T3113 equal to 4 seconds.
would anyone confirm this timer step value (what about you pix?)27th August 2007 at 13:58 #48968pixGuest
hi da architect,
sorry, i’m 100% blind about nss timers…
