i’ll check that tomorrow more into details, but first you can check the threshold of timing advance to exit the in–>out cells and the threshold of TA for out–>in cells.
then, verify the cause “ho distance” is enabled.
verify bith cells are neighbours (but it should be automatic…)
and finally, the most important test : ensure by drivetest that the HO is working or not.
Maybe there is no HO request because nobody is doing the path inner/outer while talking on the phone 🙂
check indicators Adjacencies / MATRIX / BASIC / requests, attempts and success from in to out and from out to in.
how many requests ?
