Hello all,
I face a strange problem during some LTE DL/UL drive tests;no HO message on E6474A when I use TCP/UDP DL/UL except the BCCH-SCH;there is no traffic cut,plotting Throughput over SNR/serving Cell ID shows normal values in HO region(Dl rate doesnt fall below 40 Mb DL and 15 Mb UL) so the behaviour is the same as a successful HO case from traffic point of view;when i try drive tests with ping(32 up to 1436 bits),all the HO messages are present(Measurement reports,bearer reconfiguration,etc)
Does someone have a clue what could be the isue?
PS. Drive test speed was below 50 km/h
Thank you in advance
Alex
