Hi sir can you tell me how to make 3 ltehelper in one script, and install it on one epc ??
Or i have to make also three epc to be able to run 3 ltehelper ??
I made three lte helper aiming to be able to set offset of each eNB
Or i have to make also three epc to be able to run 3 ltehelper ??
I made three lte helper aiming to be able to set offset of each eNB

Hi,
to be honest your question is rather confused. Mind to explain your issue a in a clearer way ?
Probably I'll not be able to answer and you'll need an LTE maintainer, but clarity is the first step to have an answer.
Thanks,
T.

Ok sir i'm sorry if my question is confusing for you.
Let me explain again.This is my script, here i want to make three lte helper to install on one epc

Ptr<LteHelper> lteHelper1 = CreateObject<LteHelper> ();

Hi,
The error is simply a typo error. You are using lteHelper1,2,3 and in the Handover Algorithm you use lteHelper (without a number).
I do not understand why there is a need to create 3 helpers in the first place. The configuration of the three are the same.
Also this command " lteHelper1, lteHelper2, lteHelper3 ->SetEpcHelper (epcHelper);" is in principle wrong.
It looks like you do not have the basic understanding of programming.
Regards,
K

Ok sir thanks,
Yes i was just studying this ns3 about a week ago,
I was asked by my teacher to make three lte helper for each enb to have different offset configuration
Can show you the correct writing of the script?
