Assertion Error for Large Simulation Time[LTE NS-3 Module]

[Kuldeep Gill]

Hello,

I am trying to simulate a simple LTE network without backhaul by modifying simple-lena.cc script. The code works for short simulation time (< 5 seconds) but if I want to go for higher time it gives an assertion errror at lte-ue-rrc.cc line=2887. Does anyone know

what the error is about and how can I resolve it. I am using below command to run simple-lena

./waf --command-template="gdb --args %s --ns3::ConfigStore::Filename=input-defaults.txt --ns3::ConfigStore::Mode=Load --ns3::ConfigStore::FileFormat=RawText" --run src/lte/examples/lena-simple

and this is the output for gdb:

assert failed. cond="measIdIt != m_varMeasConfig.measIdList.end ()", file=../src/lte/model/lte-ue-rrc.cc, line=2887
terminate called without an active exception

Hi,

I had the same problem here, running a simulation with several eNBs and for 300 seconds. It stopped with the same assertion failure after around 1 hour of simulation.

I ran the exact same setup again, but with different routes for the users (mobility is randomized in my code), and the error did not occur. 

If someone knows what is causing it, please let us know!

thanks,

João

Hello,

What is the function containing the ASSERT?

Hello,

I had same problem. It happened, when users move somewhere.

And I also use random mobility in my code, so it doesn't happen in the same time.

Hope someone could help, thanks.

Would you please try this patch to see whether the problem is gone or not?!
