论文摘要
对于下一个无线通信系统，主要的挑战是提供无处不在的无线访问能力，并保持服务质量和无缝的移动性管理，用于异质网络中的移动通信设备。由于移动用户的快速增长，这种需求变得更具挑战性，而用户总是需要无缝连接，而他们随时搬到其他地方。随着用户数量的增加，网络负载也增加，需要有效地执行移交过程。但是，在许多情况下，经常发生移交阻塞和不必要的移交，然后影响网络并降低其性能。问题是由于基站之间移动用户的移动而引起的，而链接连接变得较弱，而移动节点试图切换到另一个基站，以在呼叫更高的QoS（服务质量）期间具有更好的链接质量。在这项调查中，其目的是聚集研究，以帮助改善5G（第五代）蜂窝网络中的移动性管理过程。
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.
