摘　　要：为满足数据业务的增长需求和提升用户体现,LTE异构网突破了传统同构网的局限性,利用各类新技术和新设备的协同作业来实现LTE网络的持续演进。通过探讨LTE异构网的发展背景及关键技术,从规划指标、分析建模、站址选择、设备选型、协同组网五个方面研究了异构网的组网策略。根据各类型覆盖场景的特点,给出了LTE异构网分场景部署方案,并通过具体案例分析印证了LTE异构网在解决网络深度覆盖方面的优势,以期能够推动异构网的建设和发展。In order to meet the growing needs of data services and enhance user performance, LTE heterogeneous network, by breaking through the limitations of traditional isomorphic networks and by using all kinds of new technologies and new devices, achieves continuous evolution of LTE network. By exploring the development background and key technology of LTE isomer network, the networking strategy of heterogeneous network is discussed from five aspects, such as planning indicators, analysis modeling, site selection, equipment selection and cooperative networking. Based on the features of various coverage scenarios, a scenario deployment scheme for LTE isomeric networks is proposed. Based on analysis of specific case, the advantages of LTE heterogeneous network in solving network depth-coverage are confirmed, expecting to promote the construction and development of isomerism network.
