摘　　要：长期演进(ITE)网络是3GPP定义的移动宽带(MBB),满足人类通信的宽带需求,但随着机器类通信(M2M)的快速发展,如何快速高效、低成本地部署M2M网络是业界的重要方向。提出了复用GSM的基本模块,可以快速部署低成本的M2M网络,并且与现有MBB系统LTE网络共享频谱,进一步降低部署成本。仿真结果表明,对于LTE系统来说,完全有能力容纳M2M系统的频谱共享和共存的需求,证明该方案是具有现实可行性的。Long term evolution （LTE） networks is an advanced mobile broadband network defined in 3GPP （3rd Generation Partnership Project）, to satisfy the human to human communication requirement. With the quick developing of machine to machine communication requirement, how to deploy the M2M networks with a high speed, low cost and efficient manner is the definite requirement in the industry. A low cost M2M network which deploy co-sited with MBB networks and shared spectrum with MBB network was proposed. System simulations show the spectrum sharing mechanism can solve the inter-RAT interference influence and ensure the acceptable performance loss. And the mechanism is low cost and technical reasonable.
