基于用户消费习惯多选权重的垂直切换算法

针对现有异构网络垂直切换算法未能充分考虑不同用户以及同一用户不同次通信对网络资源需求有所不同的问题,提出了一种基于用户消费习惯的多选权重垂直切换算法(MWVH)。算法通过计算用户近期实时业务和非实时业务消费的期望、方差以及消费频率动态改变候选网络切换利润函数中的指标权重,得到符合用户近期消费习惯的网络选择。

Multi-weighting Vertical Handoff Algorithm Based on User Consumption Habits

According to the condition that theexist-ing vertical handoff algorithms for heterogeneous networksean＇t adequately consider the different users＂ requirements of the network resources or that of the same user in differentcommunications a multi-weighting vertical handoff algorithm based on user consumption habits is proposed-MWVH（Muhi-weighting Vertical Handoff Algorithm）. Basing on the mathematical expectation,variance and frequen-cy of users＇ recent real-time services consumption and non-real-time services consumption, the algo-rithm dynamically changes the weights of the index-esin the profit functions of candidate networks to choose the network which will be consistent with users＇ recent consumotion habits.
