Many of the service providers are planning to offer this service by 2010-2012. LTE is vast change in the telecommunication industry from circuit switched network to packet switched network and now all IP-network. In the fast changing mobile telecommunications seamless handover is important for any technology to succeed. It is desirable and beneficial from operator as well as user perspective to have seamless handover with cost effectiveness, enhanced features, and location independence not only in the case of Intra LTE network but also with the legacy networks like UMTS, GSM and CDMA that is Inter-RAT handovers. This tutorial introduces the evolution of the system and then focuses on the Evolved Packet Core, then it explains various core mobility supporting states and entities. From chapter 4 it explains in detail Intra EPC mobility like initial attach, tracking area procedures, detach procedures initiated by different entities in the core network. Finally in chapter 5 it explains in detail the Inter-RAT handovers like from E-UTRAN to UTRAN, UTRAN to E-UTRAN, E-UTRAN to GERAN, and GERAN to E-UTRAN.
