虽然蜂窝网络连接着全球超过37亿人，但其可用性和质量在各地区并不一致。配置不足和过载的网络导致网络性能差和用户体验恶化。为了解决这个问题，我们提出HybridCell：一个系统，利用本地拥有的小规模蜂窝网络，以增加超载的商业网络的操作。HybridCell是第一个允许用户使用现有SIM卡和移动的电话在商业和本地网络之间无缝切换以保持连续连接的系统。Hybrid-Cell通过识别性能较差的网络并采取行动为最终用户提供无缝的蜂窝连接来实现这一目标。使用我们在访问约旦扎塔里难民营期间观察蜂窝基础设施收集的痕迹，我们展示了HybridCell检测商业网络过载并采取行动的能力，在拥塞期间提供备用通信信道。我们表明，即使在提供商网络拒绝呼叫的情况下，由于过载，HybridCell是能够容纳用户，方便本地呼叫。
While cellular networks connect over 3.7 billion people worldwide, their availability and quality is not uniform across regions. Under-provisioned and overloaded networks lead to poor network performance and an aggravated user experience. To address this problem we propose HybridCell: a system that leverages locally-owned small-scale cellular networks to augment the operation of overloaded commercial networks. HybridCell is the first system to allow a user with their existing SIM card and mobile phone to seamlessly switch between commercial and local networks in order to maintain continuous connectivity. Hybrid-Cell accomplishes this by identifying poorly-performing networks and taking action to provide seamless cellular connectivity to end users. Using traces collected from observing the cellular infrastructure during our visit to the Za'atari refugee camp in Jordan, we demonstrate HybridCell's capability to detect and act upon commercial network overload, offering an alternate communication channel during times of congestion. We show that even in scenarios where provider networks deny calls due to overload, HybridCell is able to accommodate users and facilitate local calling.
