摘要

在LTE中提出并实现了两种无线电资源控制状态，以确保低终端功耗和高网络资源可用性。如果调优得当，在这两种状态之间转换可以优化网络性能。目前，终端在预配置静态不活动持续时间后，会从LTE_ACTIVE状态切换到LTE_IDLE状态。本文试图证明没有静态超时在任何时候对所有用户都是最优的。此外，提出了一种用户级动态决策算法，实现了用户级的细粒度优化。由于实现更高的效率与上下文感知有关，因此我们提出了一种允许UE自动学习其流量行为的解决方案。将动态算法应用于应用程序和遗留流量组合的五种不同的用户负载场景，结果表明，与固定超时情况相比，我们能够节省高达30%的电力。

Application-Aware Fast Dormancy in LTE

Two Radio Resource Control states have been proposed in LTE and implemented to ensure low UE power consumption and high network resource availability. Transiting between these two states optimizes network performance if tuned properly. Currently, a UE switches from the LTE_ACTIVE state to the LTE_IDLE state after a pre-configured static inactivity duration. This paper seeks to demonstrate that no static timeout is optimal for all users at all times. In addition, a user-level dynamic decision algorithm is proposed to have fine-grain user level optimization. Since achieving better efficiency is related to context awareness, we present a solution that allows the UE to auto-learn its traffic behavior. The dynamic algorithm was applied to five different user load scenarios of combined application and legacy traffic, and the results showed that we are able to attain power savings of up to 30% when compared to the fixed timeout case.
