Please find my inputs as below:
1. One eNodeB can support multiple cell in case of macro, it supports up to 3 cells and each cell of same eNodeB can support one Tracking area but it can broadcast up to 6 PLMNs.
2. Tracking area identity is combination of PLMN + Tracking area code. In essence, one cell can have 6 tracking area identities.
3. Each cell of an eNodeB may belong to different tracking area code. Please refer SIB1 for tracking area code being broadcasted.
4. One tracking can cover multiple eNodeB as well as cells belong to same eNodeB.

Suppose a eNB is shared between two operators so can he have multiple tracking area code ?

I just thought of a situation ,

As each ENB does S1 connection with MME.so consider 3 ENBs(those are nearer to each other) did S1-Setup with a particular MME.

After S1-Set up done can we have/add some intelligence (Based on some identity ) at MME to know who all are neighbor for whom?

If we will know about this we can make X2 -relation with neighbor easily ,so that we can reduce the overhead of getting info of neighbor ENBs.

May be this question is simple and basic but I just want some clear information about emergency attach? What is emergency attach? why and when we need it? What are the configurations that are to be done at ENB side?
