The paper analyzes potential ways of reducing data service interruption time during handover in LTE and 5G
Efficient and seamless mobility is one of the primary objectives for each cellular technology.
We have built a research prototype of UMTS access point called a UMTS IP router (UIP). This network element combines the hierarchy of GGSN, SGSN, RNC and NodeB in a single base station.

In this paper we address seamless roaming for SIP-based services across current cellular telecommunications networks and emerging all-IP wireless networks, such as those using 3G and WiFi networks.
Session-based IP applications, such as Internet telephony, are an important component of the emerging mobile Internet.
In this paper, we provide a comprehensive review of the handover process in heterogeneous networks (HetNets), and identify technical challenges in mobility management.
The 5G vision is to create a network that outperforms the current mobile networks in terms of flexibility, performance and use cases.
