A Survey Mobility Management in 5G Networks
For the next wireless communication systems, the major challenges are to
provide ubiquitous wireless access abilities and maintain the quality of
service and seamless mobility management for mobile communication devices in
heterogeneous networks. Due to the rapid growth of mobile users, this demand
becomes more challenging where the users always require seamless connectivity
while they move to other places at any time. As the number of users increases,
the network load also increases, the handover process needs to be performed in
an efficient way. However, in many situations, the handover blocking, and
unnecessary handover frequently happens, then affect the network and reduces
its performance. The problem arises with the movement of mobile users between
base stations while the link connectivity becomes weaker and the mobile node
tries to switch to another base station to have a better link quality during a
call for higher QoS (Quality of Service). In this survey, it is aimed to gather
together the studies that help to improve mobility management processes in 5G
(Fifth Generation) cellular networks.Comment: 6 pages, 2 figures, pre-print, surve
