Abstract

In this paper we present our solution for intelligent network interface selection and (vertical) handover control for heterogeneous multi-access environments. The 4th generation mobile communication system is seen as a combination of several access technologies optimized for different purposes. A combination of these access technologies can constitute, with intelligent control, a 4G access with capabilities to support various application and user requirements and preferences. A policy based vertical handover controller system, called VERHO, utilizes input from several cross-layer sources, the Mobile IPv6 protocol and network interface selection to achieve both proactive and intelligent vertical handovers between a variety of access interfaces. Real-time link status information, access point scanning support, user profiles, policies and Multiple Attribute Decision Making algorithms provide flexibility in interface selection and result in an Always-Best-Connected access for the user. We present the VERHO architecture along with discussing and showing the possible benefits of such system in the future.

异构无线环境下多主移动主机的多接口管理

本文提出了异构多址环境下智能网络接口选择和(垂直)切换控制的解决方案。第四代移动通信系统被视为针对不同目的进行优化的几种接入技术的组合。通过智能控制，这些接入技术的组合可以构成支持各种应用和用户需求和偏好的4G接入。一个基于策略的垂直切换控制器系统，称为VERHO，利用来自多个跨层源的输入、移动IPv6协议和网络接口选择来实现各种访问接口之间的主动和智能垂直切换。实时链路状态信息、接入点扫描支持、用户配置文件、策略和多属性决策算法为接口选择提供了灵活性，并为用户提供了始终最佳连接的访问。我们介绍了VERHO架构，并讨论和展示了这种系统在未来可能带来的好处。
