EXPERTS : RAB SSR vs RRC SSR

[white_Noise]

Dears,

I have worked on two different networks, and the trend for the RAB and RRC Setup success rate and blocking were different, as one had the RRC has always less blocking and better SSR, where the other was the exact opposite, where the RAB blocking is less and the SSR is better.

I coulnd't find an exatc answer for this, but I think that the priority given to handovers over setting a new service up has to do with the better RAB SSR, while the relatively low resources needed for an RRC makes it less possible to get an RRC blocking.

I would appreciate your Inputs and feedback in this regard.

Not sure what exactly you mean but if you mean why is RRC worse than RAB, the answer is that they are 2 completely different processes. Also, the RAB only starts once the RRC ends, so the chances or success are much higher. Finally, RRC is used for registration and therefore, you can have high failure rates near RNC boundaries which tend to have poorer coverage. Hope that helps.....

No Actually it didn't help, since you didn't understand the question and started explaining very basic principles that are well know to everyone,it was clear that I asking in terms of blocking, since the RRC consumes much less resources in most of the cases so in case of congestion, what you said doesn't apply

Well maybe if you explained what your problem is a clear way, it would be easier to answer. You won't be getting a whole lot of reputations by getting into a huff when people try to help you.

Are these two networks from one and the same vendor? if yes compare the config files and see the difference.
