I have an interesting case.
I have two sites:
One site is ZTE_3G and another NOKIA_3G-4G.
I do a Handover in ZTE site: HO ZTE_3G <-> NOKIA_3G site. And when it the call finish, it don’t do reselection 3G to 4G NOKIA.
But when I Originate a call in NOKIA_3G, after call finish it do reelection without problem to NOKIA_4G.
The question is: Why it does’t to reselection 3G to 4G NOKIA in the first case?
