基于多终端协同的终端与网络协同选择算法研究

摘要

User experience can be greatly improved by using multi-terminal cooperation mechanism in wireless heterogeneous environ-ment,when single terminal or network capacity is limited. It has been a key issue to select suitable terminals and corresponding access net-works instantly. Therefore,propose a multi-terminal cooperation mechanism,which integrates the terminal and its access network as a vir-tual terminal unit. With terminal-network cooperative selection algorithm,one or more virtual terminal units would be selected to form a cooperative terminal set to provide service. Simulation results show that multi-terminal cooperation mechanism can help save energy con-sumption of terminals on the premise of ensuring the data rates.%异构无线网络环境下采用多终端协同机制可以在单终端或网络能力有限的情况下提升用户的业务体验，即时性地选择合适的终端和相应的网络成为其中一个关键的问题。为此提出了一种多终端协同机制，将终端与其接入网络看作一个整体称之为虚拟终端单元，采用终端与网络协同选择算法选择一个或多个虚拟终端单元形成协同终端集提供业务。仿真结果表明，多终端协同机制可以在保证业务数据速率的前提下有效地减少能量的消耗。
