由于设备数量多、数据传输量小、应用范围广，蜂窝网络上的机器到机器(M2M)通信面临着巨大的挑战。事实证明，基于通用分组无线业务(GPRS)接入的当前解决方案不足以支持M2M生态系统。因此，高级蜂窝网络版本，如长期演进(LTE)和LTE-A(LTE-A)，应该有效地迎合M2M通信。然而，信令开销的增加和多样化的服务质量(Qos)需求要求开发新的灵活调度算法。在这篇文章中，我们介绍了在现有和未来的蜂窝基础设施上促进M2M调度所面临的挑战，回顾了相关的建议，提供了一些初步的解决方案，并确定了新的观点，为高效和顺利地迁移到支持M2M的宽带蜂窝系统铺平了道路。
Machine-to-machine (M2M) communications over cellular networks pose significant challenges as a result of the large number of devices, small data transmissions, and vast applications range. Current solutions based on general packet radio service (GPRS) access proved to be inadequate for supporting the M2M ecosystem. Therefore, advanced cellular network releases, such as long-term evolution (LTE) and LTE-Advanced (LTE-A), should efficiently cater to M2M communications. However, the increase in signaling overhead and diverse quality-of-service (QoS) requirements calls for the development of novel flexible scheduling algorithms. In this article, we present the challenges in facilitating M2M scheduling over existing and future cellular infrastructures, review the related proposals, provide some initial solutions, and identify new perspectives, which pave the way for efficient and smooth migration to M2M-enabled broadband cellular systems.
