lena-x2-handover-measures,, Triggering HO automatically ?

[Hadeel Alghafari]

Hi,

Actually I’m trying to understand the example about x2 handover. And as I saw they triggered the handover action manually by using:

     //lteHelper->HandoverRequest (Seconds (0.100), ueLteDevs.Get (0), enbLteDevs.Get (0), enbLteDevs.Get (1));

 And my question is:

How can I enable and disable the handover to be triggered automatically?

Can anybody help?

Thanks

Hi,

The lena-x2-handover-measures.cc example in /src/lte/examples provides automatic HO, which you can contol like this

  lteHelper->SetHandoverAlgorithmType ("ns3::A2A4RsrqHandoverAlgorithm");

  lteHelper->SetHandoverAlgorithmAttribute ("ServingCellThreshold",

  UintegerValue (30));

  lteHelper->SetHandoverAlgorithmAttribute ("NeighbourCellOffset",

UintegerValue (1));

Oh, thanks alot 

 sorry for asking silly questions but I'm just a beginner!! I want to know how I can notice the handovers that happened and count them for example for further studying, also I want to know how the procedure here take place , for example how the UE sends the reports of measurements to the ENB so it decides to start a handover ?   

please can you help me ..

Thanks alot

hello sir,
i have a problem when i try to make X2 Handover using A2A4RsrqHandoverAlgorithm, i using 2 ENB and a UE that moving from enb1 to enb2, i already using this

  lteHelper->SetHandoverAlgorithmType ("ns3::A2A4RsrqHandoverAlgorithm");

  lteHelper->SetHandoverAlgorithmAttribute ("ServingCellThreshold",

  UintegerValue (30));

  lteHelper->SetHandoverAlgorithmAttribute ("NeighbourCellOffset",

UintegerValue (1));

but the UE would'nt do handover,
Could you please help me on this ?
Best Regard :)
