在文献中已经报道了许多用户移动性预测算法。这些可用于未来无线网络中的资源预留和服务预配置/适配，以提供服务质量保证。然而，我们使用测量的蜂窝性能对其中一些技术进行的分析表明，这些模型不能准确地表示用户的移动模式。因此，资源预留方案需要预留过多的资源，预配置/适配效果不佳。为了克服这一问题，我们提出了一种自适应用户移动性预测算法，将预留和配置过程限制在用户周围的小区子集。然后通过基于测量数据的仿真验证了该方案的可行性和有效性。
A number of user mobility prediction algorithms have been reported in the literature. These may be used for resource reservation and service pre-configuration/adaptation in future wireless networks to provide QoS guarantees. However, our analysis of some of these techniques using measured cellular performance shows that these models do not accurately represent the mobility patterns of users. As a result, resource reservation schemes need to reserve excessive resources, and the pre-configuration/adaptation does not work well. To overcome this, we propose an adaptive user mobility prediction algorithm that limits the reservation and configuration procedure to a subset of cells around the user. The viability and effectiveness of the proposed scheme is then demonstrated through a simulation based on measured data.
