Actually handover happens when eNodeB change.
It is of 2 types S1 based or X2 based.
Cell change is not considered as part of handover and usually handled by MME itself
You can check 23.401 for more info

How target enodeb will confirm if the incoming user is a genuine user or not?
Is there any IE exchanged during HO preparation phase? I am expecting that during X2 handover AS SECURITY INFO in UE context is very helpful? Is that or not?
In case of horizontal handover UE is moved from one cell to another cell But with in the same ENB. So in this case how the security is activated and how key derived ?
In sib4 we will broadcast intra frequency cells information, will it help to get cgi info of cells which are we broadcasting in SIB4.
Please suggest.
