    Failure Reasons in RRC:
    1. Coverage Issue
    2. Interference Issue
    3. PRACH Usage High
    4. Configuration Issue
    5. Paging Load High

    There is RRC failure in Cell due to cause code RRCsig.RRcsetup time expires before signal reach to UE.Please support to resolve.

    Hello,
    I need your support on how to troubleshoot on high MTC call attempt on 4G,during a drive test as I can see paging received,nothing happened after this message(no rrc connection request,…),radio condition ok ,except of 3 failures dur to SNR =-6
    what can be the cause?the mobility can impact the MTC call attempt failure due to delay paging?
    Thanks,

    Hi,

    Are you certain the Paging was intended for your UE ? I find it strange that the UE does not proceed with a RRC Connection.
    Did the UE properly attach to the network ? Performed Tracking Area Updates ? What about MOC ?

    Hi,
    Thanks for your reply
    I agree with you and I checked M-TMSI in a previous messages before paging like RRC connection req(MOC) or tracking area update and the M-TMSI in a a paging didn’t match any one nor in RRC request or tracking area update .The cause is B-party is unreachable,it’s look like the device is down,or not connected but I don’t know how to confirm ,prove that
    Thanks,

    Hi,

    Well, I would just attempt a MOC and see how it goes. If MOC is made, then it means the UE is attached and capable of doing voice calls (through VOLTE I assume ?).

    Try to do the MTC after that.

    If MOC is not possible, then you know for sure there’s an issue. I would investigate the ATTACH procedure (which you can trace by doing an “airplane” mode ON/OFF during the tracing)

    Also, try to do packet transfers. If those are possible but not the VOLTE, then it’s something else altogether.

    cheers/pix
