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.
