The ongoing efforts in the research, development
and standardization of 5G, by both industry and academia,
have resulted in the identification of enablers (Software Defined
Networks, Network Function Virtualization, Distributed Mobility
Management, etc.) and critical areas (Mobility management,
Interference management, Joint access-backhaul mechanisms,
etc.) that will help achieve the 5G objectives. During these efforts,
it has also been identified that the 5G networks, due to their high
degree of heterogeneity, high QoS demand and the inevitable
density (both in terms of access points and users), will need to
have efficient joint backhaul and access mechanisms as well as
enhanced mobility management mechanisms in order to be effective,
efficient and ubiquitous. Therefore, in this paper, we first
provide a discussion on the evolution of the backhaul scenario,
and the necessity for joint access and backhaul optimization.
Subsequently, and since mobility management mechanisms can
entail the availability, reliability and heterogeneity of the future
backhaul/fronthaul networks as parameters in determining the
most optimal solution for a given context, a study with regards
to the effect of future backhaul/fronthaul scenarios on the design
and implementation of mobility management solutions in 5G
networks has been performed.
