"msg="AddUeMeasReportConfig may not be called after the simulation has run", file=../src/lte/model/lte-enb-rrc.cc, line=1936 terminate called without an active exception."

[HaiZhou Bao]

Dear all,

I find the simulation code vmasc-lte integration.cc on the website: https://bitbucket.org/sucar/vmasc-clustering/wiki/Home.

When the code is run,  I find that there is an error, and then I use gdb command to debug the code.

When I debug the code, the last line "enbLteDevs = lteHelper->InstallEnbDevice(enbNodes);" in  LteController::InitLTE() {} of  vmasc-lte integration.cc  

encountered  an error as follow:

"msg="AddUeMeasReportConfig may not be called after the simulation has run", file=../src/lte/model/lte-enb-rrc.cc, line=1936  terminate called without an active exception."

 

The call  sequence of  the code is:

Simulator::Schedule (Seconds (55.0), &Start, roads); 

----->  enbLteDevs = lteHelper->InstallEnbDevice(enbNodes); in  LteController::InitLTE(){} in your vmasc-lte integration.cc

----->  Ptr<NetDevice> device = InstallSingleEnbDevice (node); in the fuction LteHelper::InstallEnbDevice (NodeContainer c) {} in lte-helper.cc

----->  dev->Initialize (); in the function  Ptr<NetDevice> LteHelper::InstallSingleEnbDevice (Ptr<Node> n) in lte-helper.cc 

----->  current->DoInitialize (); in the function void Object::Initialize (void){} in Object.cc

----->  m_measId = m_anrSapUser->AddUeMeasReportConfigForAnr (reportConfig); in  void LteAnr::DoInitialize (){} in lte-anr.cc 

----->  return m_owner->DoAddUeMeasReportConfigForAnr (reportConfig); in  MemberLteAnrSapUser<C>::AddUeMeasReportConfigForAnr (LteRrcSap::ReportConfigEutra reportConfig){} in  lte-anr-sap.h

----->  uint8_t measId = AddUeMeasReportConfig (reportConfig); in uint8_t LteEnbRrc::DoAddUeMeasReportConfigForAnr (LteRrcSap::ReportConfigEutra reportConfig){} in lte-enb-rrc.cc

--- -> 

        if (Simulator::Now () != Seconds (0))

        {

           NS_FATAL_ERROR ("AddUeMeasReportConfig may not be called after the simulation has run");

        }  

       in  uint8_t LteEnbRrc::AddUeMeasReportConfig (LteRrcSap::ReportConfigEutra config){} in lte-enb-rrc.cc.

Because you call the start()  Simulator::Schedule (Seconds (55.0), &Start, roads), the Simulation::Now()==55 !=Seconds(0), thus  NS_FATAL_ERROR ("AddUeMeasReportConfig may not be called after the simulation has run");

Please help me to solve this problem, I have got stuck here for a long time.

Can anyone give me some advice? I wanna to known whether  the code  "enbLteDevs = lteHelper->InstallEnbDevice(enbNodes);  in the function LteController::InitLTE() {} of vmasc-lte integration.cc " should be called at Seconds(0) or not? Or there are some problems that I ignore?

Thanks & Best Regards,
