Hi all,
Evaluation of smartphone impact on network is needed.
Some advice please on which counters, and KPI to follow to best estimate this influence of smartphones on our 3G network.
Network vendor is NSN.
Ideas and advice are welcome.
Thanks!

Hi Banisha,
One of most crucial impacts of the smartphones on a 3G nw is Signalling on the RNC (cpu load), and the constant change of RRC states, usually caused by chatty apps, there is already very interesting reports about this done by several vendors and other company's, you can find it here in the forum, (e.g. Signals research (very good) , Huawei, ...)
Hope it helps

I'm extremely interested in this posts, I'm looking to understand device performance for Smartphones on 4G LTE networks, the networks are E******* 4G LTE and Alcatel Lucent 4G LTE. I'm interested in finding if anyone can share Tektronix IrisView traffic samples of NAS EMM/ESM Failure cause codes sample files. I need to find out which devices are experiencing which types of failure cause codes and why in the network, and then finally compare between E******* and Alcatel Lucent. The list of failure cause codes associated to procedures is as follows, if any one can send any LTE traffic captures and also any experience/case studies that would be extremely helpful?
In the coming weeks I will be putting some examples together for my specific customer but i need some ideas from other networks?

One example I saw was E******* 4G network, they had enable a patch which improved the RRC drop rate nation wide, (change of a parameter on the Implicit Detach) the results were compared to all the devices and all had seen an improvement apart from the ******** droid model which was still experiencing a lot of problems.
Such are examples that I'm looking for? plus any 4G traffic captures from Tek/JDSU/Anritsu...anyone basically?

Hi,
These are the documents that I already read. I am now interested in specific counters and KPI that can be followed on NSN vendor.
The goal is to make smartphone report that can be later compared to another network with different equipment vendor and compare smartphone impact.

Hi Tyberry,
any evolution regarding 4G smartphones signaling issues?
I'm trying to focus more less on the same thing, what should be the impact of the chatty apps in a 4g environment, and what should be the best approach (what link should be monitored, S1 mme? , Sgi ? ) the load caused by this kind of apps will be mainly signalling? lot´s of questions :L
anyone would like to comment
thanks
