The growing number of mobile devices and the demand for user data by 2030 ‎are expected to put pressure on the current mobile network in an unprecedented ‎way.‎‏ ‏Future mobile networks must have several requirements regarding data ‎amount, latency, quality of service and experience, mobility, spectrum and energy ‎efficiency. Therefore, efforts have recently begun for more efficient mobile ‎network solutions. To this end, load balancing has attracted much attention as a ‎promising solution for greater resource utilization, improved system performance, ‎and reduced operating costs.‎‏ ‏This is an effective way to balance traffic and reduce ‎congestion in heterogeneous networks in future 5G/IMT-2020 networks. Load ‎Balancing is one of the most important tasks required to maximize network ‎performance, scalability and robustness. Nowadays, with the emergence of ‎Software-Defined Networking (SDN), Load Balancing for SDN has become a very ‎important issue in future network 5G/IMT-2020 . SDN allows for load balancers that ‎are programmable and provides the flexibility for one to design and implement own ‎load balancing strategies. In this survey, we highlight the methods of load balancing ‎based on SDN networks and prospective load balancing requirements on 5G ‎networks .‎
