hi usama,
its like in situation where boss asking to move to other department by sending "RRC reconfiguration", and as a good soldier we always have option either to accept or reject him by sending RRC physical reconf failure.
what next the boss always has 2 option as well: keep u in the team or sending disconnect message a.k.a drop call.
it is very easy to understand isn't it ?

hard part is to know the reason of that failure

thanks bro if possible can u list some of the failures and procedure to reduce recofiguration failures OR better if u can attached some document......


In addition one more question: What is cause to Regestration Fail in 3G when RNC sends RRC Connection Reject to UE with cause Registration Failure what does it mean and how we can reduce it????

[usama0795]

need some answers is high number of high registration_failures becuse of admission control thing.....

[tukangoptim]

afaik admission control is not applicable for rrc registration.
how do u find exactly the cause of admisson control ?

below is for your reference about registration, it should be reduced as huge number of attempt will consume resources.
u can try basic thing first like offset in lac border.
