“…They are the functions that are responsible for enabling the mobile UE to switch connections from one cell to another during movement without any disruption in the ideal case. Several mobility functions are present, such as the mobile Internet Protocol (IP), handover decision, handover optimization functions [40][41][42], and rerouting mobile protocols [43][44][45]. Some wireless networks support these functions, while others do not.…”

Ensuring a seamless connection during the mobility of various User Equipment (UE) will be one of the major challenges facing the practical implementation of the Fifth Generation (5G) networks and beyond. Several key determinants will significantly contribute to numerous mobility challenges. One of the most important determinants is the use of millimeter waves (mm-waves) as it is characterized by high path loss. The inclusion of various types of small coverage Base Stations (BSs), such as Picocell, Femtocell and drone-based BSs is another challenge. Other issues include the use of Dual Connectivity (DC), Carrier Aggregation (CA), the massive growth of mobiles connections, network diversity, the emergence of connected drones (as BS or UE), ultra-dense network, inefficient optimization processes, central optimization operation, partial optimization, complex relation in optimization operations, and the use of inefficient handover decision algorithms. The relationship between these processes and diverse wireless technologies can cause growing concerns in relation to handover associated with mobility. The risk becomes critical with high mobility speed scenarios. Therefore, mobility issues and their determinants must be efficiently addressed. This paper aims to provide an overview of mobility management in 5G networks. The work examines key factors that will significantly contribute to the increase of mobility issues. Furthermore, the innovative, advanced, efficient, and smart handover techniques that have been introduced in 5G networks are discussed. The study also highlights the main challenges facing UEs' mobility as well as future research directions on mobility management in 5G networks and beyond.

“…In this network structure, base stations are ATM switches equipped with one wireless radio port adapter card and act as gateways for communication between a mobile station and the wired ATM network. The geographical area for which a base station radio port acts as the gateway is called its cell [10], and one base station covers one cell. Nineteen cells are connected to a cluster switch that manages intracluster handoffs.…”

With growing demand for higher bandwidth multimedia services in the wireless domain over the past few years, wireless asynchronous transfer mode (ATM) has emerged as a fine solution. Wireless ATM provides mobility support for mobile ATM users as they move among base stations. One of the key issues to support user mobility is the handoff. For a relatively smaller cell environment in wireless ATM, a handoff scheme should exhibit low handoff delay. Efficient usage of network resources is also required. In this paper, we propose a fast rerouting scheme for wireless ATM referred to as a path reservation scheme. For localized handoffs, we adopt a wireless cell clustering method. Cell grouping and a path reservation technique are proposed to achieve fast handoffs. This paper presents an analysis of the proposed scheme and simulation results of several handoff schemes compared with the proposed scheme. From the simulation results, our path reservation scheme achieves low handoff delay and efficient usage of network resources such as buffer and bandwidth requirements.
