Intra LTE handover – Intra MME/SGW handover – Neither UE’s serving MME nor SGW is changed after handover. Inter LTE handover - UE’s serving MME and/or SGW is changed after handover Inter MME HO: UE’s serving MME is changed, SGW remains unchanged after handover. Inter SGW handover: UE’s MME is unchanged, SGW is changed after handover. Inter MME/SGW Handover: Both MME and SGW are changed after handover. Inter
