The primary focus of this course is to: introduce the next generation mobile networks, including both Cellular and WLAN technologies in great detail; discuss various types of IP-based mobility protocols, namely Mobile-IP, Mobile IPv6, ProxyMIPv6, SIP-mobility, and Cellular IP; and systems optimization techniques to support seamless handover during Inter RAT handover (e.g., 4G, WLAN). This course will briefly introduce the principles of cellular communications system and will then move on to describe the evolution of different generations of cellular systems including 2G, 3G, 4G, and 5G as being defined in 3GPP. At the same time it will discuss IEEE WLAN standards as developed by IEEE 802 working group including 802.11 (a, b, g, n) and 802.11 (ax, ay, ac). The Media Independent Handover standard IEEE 802.21 (e.g., integrating WLAN and 3G/4G cellular networks to provide session/service continuity) is also introduced. This course will describe the 4G Long Term Evolution (LTE) in detail, covering its various components—namely Evolved UMTS Terrestrial Radio Access Network (E-UTRAN), EPC (Evolved Packet Network), and IMS (IP Multimedia Subsystem)—and all the associated interfaces and protocols. The topics include: protocol architecture, bearer management, signaling, radio resource control (RRC), packet data convergence protocol (PDCP), radio link control (RLC), and MAC. In addition, the role of universal subscriber identity module (USIM), eNodeB, mobility management entity (MME), serving gateway (S-GW), packet data network gateway (P-GW), and home subscription server (HSS) as well as the call flow across these various nodes will be presented. LTE security will be covered as well. The voice over LTE (VoLTE), self-organizing network (SON), LTE-direct, and LTE-Advanced [including coordinated multipoint (CoMP), carrier aggregation, and Inter-cell interference coordination (ICIC)] will be presented. The course will present various deployment use cases and experimental results from the open-source testbeds. The course will describe the current efforts on 5G evolution and will touch upon various 5G pillars, namely SDN (Software Defined Networking), Network Function Virtualization, Cloud RAN, Network Slicing, Mobile Edge Cloud, and Security. The course will also highlight various standards activities within 3GPP, IEEE, IETF, NGMN, and ITU and will introduce some research problems for future study in the mobility area.
