I believe from Inter-LTE you means one of these: Inter-MME, Inter-S-GW, Inter-MME/S-GW Handover

s sir inter-mme/sgw

Now what is the question or doubt?

---

I think that your question is related to inter frequency handover ?

---

i want to know when sgw/mme changes is it because of frequency changes or changes to another mmepool within same frequency?

---

Not just frequency, it could be because of new eNB is in different MME POOL.

With respect to your question "Inter LTE handover in X2AP" , first thing should remember that X2 handover is applicable when there is no change in MME. In case of X2 handover, SGW may gets changed since UE is moved to a target eNodeB which is being served by a different SGW.
