When an eNodeB supports more than one cells then each cell at the enodeb would have different PCI . what happens with cell identity ? Does each cell has different cell Identity or same ?

I checked S1-AP SETUP REQ message which is originated by eNodeB towards MME. It has only one Global EnodeB Identity and It may carry information of all the max no. (256) of supported cells within the same S1-AP SETUP REQ message. So I conclude that all cells supported by an eNodeB would share same Global Cell Identity.
Since each cell has its own PCI. In this way, Many PCI map to same global cell identity.

Please correct me if I concluded wrongly.

LTE: In RRC connected mode, when an UE moves from one cell to another cell what messaging happen ?

If I am right, an eNodeB can support multiple cells and each cell has different pci.
Now suppose enodeB has two cells i.e cell1 and cell2. If I am going right, both the cell(s) should have different PCIs.
I have assumed UE is attached to cell1 and due to mobility, it is moved to cell2. During this movement, what message shall be exchanged between UE and enodeB. And Is there any message send to MME regarding the new cell ?

In the paging message send from MME to eNB , which paging ue identity is used ?

PagingUE-Identity ::= CHOICE {
s-TMSI S-TMSI,
imsi IMSI,
...
}

As pagingUE identity should contain any one of these in paging message so how MME decides which one to send, though for security purpose MME prefers t-o send send S-TMSI but in which scenarion MME wil use imsi as paging ue identity.
