在本文中，我们提出了ICELLSPEED，这是一种在设备上的解决方案，以通过证实未实现的性能潜力来提高数据访问速度。我们发现在当今的移动网络中遗漏了性能潜力，因为用户设备获得的数据速度远低于设备所能获得的。该问题植根于当前的单元选择实践，该实践错过了提供更快访问速度的良好候选单元，因此减少了移动网络中可用功能的利用。我们设计ICELLSPEED，以促进网络控制的细胞选择，并为更理想的细胞提供主动的设备侧辅助。我们对AT＆T和Verizon的评估证实了其有效性。 Icellspeed在79％的测试位置将数据访问速度提高了10 Mbps（在29％的位置> 25Mbps，最高为80.6 Mbps）。它以62.5％的位置将访问速度加倍，增益高达28.4倍。数据集可在[9]上找到。
In this paper, we propose iCellSpeed, an on-device solution to increase data access speed by substantiating unrealized performance potentials. We find that performance potentials are missed in today's mobile networks, as the data speed a user device gets is much lower than what the device could get. The issue is rooted in the current cell selection practice, which misses good candidate cells that offer faster access speed, thus under-utilizing the available capabilities in mobile networks. We design iCellSpeed to facilitate network-controlled cell selection with proactive device-side assistance towards more desirable cells. Our evaluation over AT&T and Verizon confirms its effectiveness. iCellSpeed increases data access speed by more than 10 Mbps at 79% of test locations (> 25Mbps at 29% of locations, up to 80.6 Mbps). It doubles access speed at 62.5% of locations with the gain up to 28.4x. Datasets are available at [9].
