“…In recent years, using SDN controller's capability of managing subflows, MPTCP has been tested for seamless handover. The works in [27], [28] verified the feasibility of MPTCP-based handover methods in mobile scenarios, where MPTCP had to establish a new dataflow connection with a new network. However, these works did not clearly illustrate the signaling process or path management strategies for MPTCP during handover, especially the process of how MPTCP establishes a new connection and migrates data transmission to the target network.…”

“…However, these works used only one interface during the vertical handover, which requires link reconnection or data migration, thus inevitably bringing service delays, or even breaks. Alternatively, in [25] the authors discussed MPTCP as a potential solution for mobility-related service continuity issues, and several works [25]- [28] investigated MPTCPbased seamless handover. Early works on MPTCP [29], [30] focused on improving MPTCP throughputs in static scenarios without considering handovers.…”

In this paper, the problem of vertical handover in software-defined network (SDN) based heterogeneous networks (HetNets) is studied. In the studied model, HetNets are required to offer diverse services for mobile users. Using an SDN controller, HetNets have the capability of managing users' access and mobility issues but still have the problems of ping-pong effect and service interruption during vertical handover. To solve these problems, a mobility-aware seamless handover method based on multipath transmission control protocol (MPTCP) is proposed. The proposed handover method is executed in the controller of the software-defined HetNets (SDHetNets) and consists of three steps: location prediction, network selection, and handover execution. In particular, the method first predicts the user's location in the next moment with an echo state network (ESN). Given the predicted location, the SDHetNet controller can determine the candidate network set for the handover to preallocate network wireless resources. Second, the target network is selected through fuzzy analytic hierarchical process (FAHP) algorithm, jointly considering user preferences, service requirements, network attributes, and user mobility patterns. Then, seamless handover is realized through the proposed MPTCPbased handover mechanism. Simulations using real-world user trajectory data from Korea Advanced Institute of Science & Technology show that the proposed method can reduce the handover times by 10.85% to 29.12% compared with traditional methods. The proposed method also maintains at least one MPTCP subflow connected during the handover process and achieves a seamless handover.

“…Also, they proposed the converged SDN-based architecture, including WLAN and LTE networks, and designed the handover workflow, which supports to measure the seamless convergence during the seamless mobility. The paper [10] proposed a seamless handover method for heterogeneous wireless networks based on SDN architecture. In this method, the deployment of the SDN control plane supports the collection of real-time network attributes and mobility information to calculate the target network, thus reducing unnecessary handovers and decreasing the handover delay.…”

The mobility of user equipment (UE) in cellular network is a challenging issue in terms of its management. Current traditional handover in Long-Term Evolution (LTE) network is managed by evolved Node B or eNodeB (eNB) which is a decentralized solution. In contrast to existing technology, software defined network (SDN) has the capability of serving the packets of the switching equipment without involving the SDN controller except for the first one. We have proposed an SDN-based centralized solution for handover management in LTE network. Based on our solution, the handover is being managed by SDN controller which keeps track of the overall network management and dictates the flow entries to the OpenFlow switches in the network. In our testbed, two UEs are connected to two eNBs, and one of the UE performs a handover from one eNB to other eNB. It enhances the performance of the network in terms of reducing the delay while performing the handover and increasing the data rate of the running application. The initial delay will be bit higher due to the initial flow entry absence in the flow tables of the switches; later, the delay will be reduced. It is evident from the results that our approach keeps track of the overall network at centralized controller with improved performance.

“…The simulation results show that the proposed method is successful in finding cells with strong signal strength, long sojourn time and lightly loaded according to the direction of movement of the UE. In [91], it is aimed to select the most suitable cell for an uninterrupted HO operation by using fuzzy analytical hierarchy process (FAHP) and multipath transmission control protocol (MPTCP) in SDN based Het-Nets according to service needs and user preferences. While FAHP is used to select the most suitable cell with the data it receives from SDN, MPTCP provides the assurance of uninterrupted connection.…”

With the rapid increase in the number of mobile users, wireless access technologies are evolving to provide mobile users with high data rates and support new applications that include both human and machine-type communications. Heterogeneous networks (HetNets), created by the joint installation of macro cells and a large number of densely deployed small cells, are considered an important solution to deal with the increasing network capacity demands and provide high coverage to wireless users in future fifth generation (5G) wireless networks. Due to the increasing complexity of network topology in 5G HetNets with the integration of many different base station types, in 5G architecture mobility management has many challenges. Intense deployment of small cells, along with many advantages it provides, brings important mobility management problems such as frequent handover (HO), HO failure, HO delays, ping-pong HO and high energy consumption which will result in lower user experience and heavy signal loads. In this paper, we provide a comprehensive study on the mobility management in 5G HetNet in terms of radio resource control, the initial access and registration procedure of the user equipment (UE) to the network, the paging procedure that provides the location of the UE within the network, connected mode mobility management schemes and beam level mobility and beam management. Besides, this paper addresses the challenges and suggest possible solutions for the 5G mobility management.
