UMTS/WLAN覆盖网络中电源管理的接口选择
Interface Selection for Power Management in UMTS/WLAN Overlaying Network
摘要：
接入网络的多种选择提供了不同的机会，并克服了其他技术的局限性。接口的优化选择是支持多接口的移动终端实现无缝切换和功耗优化的一大挑战。无缝切换、资源管理、支持QoS的CAC和降低移动终端功耗的多接口管理是UMTS/WLAN覆盖网络中最重要的问题。两个接口的同时接入可以减少异构切换中的切换延迟和数据丢失。MN可以保持一个接口连接，而其他接口可以用于切换过程。但是两个接口的接入增加了MN中的功率消耗。本文提出了一种有效的接口选择方案，包括接口选择算法、接口选择机制和考虑电池功耗的CAC。MN的电池电量水平和目标接口中的QoS/QoE的提供被认为是我们的接口选择算法的重要参数。
英文摘要：
The multiple choices of access networks offer different opportunities and overcome the limitations of other technologies. Optimal selection of interface is a big challenge for multiple interfaces supported mobile terminals to make a seamless handover and to optimize the power consumption. Seamless handover, resource management, and CAC to support QoS and multiple interface management to reduce power consumption in mobile terminal are the most important issues for the UMTS/WLAN overlaying network. The access of both interfaces simultaneously can reduce the handover latency and data loss in heterogeneous handover. The MN may maintain one interface connection while other interface can be used for handover process. But the access of both interfaces increases the consumption of power in MN. In this paper we present an efficient interface selection scheme including interface selection algorithms, interface selection mechanism and CAC considering battery power consumption for overlaying networks. MN's battery power level and provision of QoS/QoE in the target interface are considered as important parameters for our interface selection algorithm.
