A communication method for use in a communications system, the communications system comprising a network server, a plurality of base stations and a plurality of network elements included in a bearer network, wherein the plurality of base stations are respectively connected to the plurality of network elements in a one-to-one corresponding correspondence, wherein the method is performed by the network server, wherein the method comprises: determining a first correspondence, wherein the first correspondence is a correspondence between geographical location information of the base stations and network element identifiers of the corresponding network elements; obtaining a first connection relationship based on geographical location information of the base stations, wherein the first connection relationship is a connection relationship between the base stations; converting the first connection relationship into a second connection relationship based on the first correspondence, wherein the second connection relationship is a topological connection relationship between the network elements identifiers of the corresponding network elements comprised in the bearer network; and automatically generating a service connection configuration of the bearer network based on the second connection relationship; wherein the converting the first connection relationship into a second connection relationship based on the first correspondence specifically comprises: determining the second connection relationship based on the first correspondence and a second correspondence, wherein the second correspondence is a correspondence between the geographical location information of the base stations and ports of the corresponding network elements; wherein the automatically generating a service connection configuration of the bearer network based on the second connection relationship comprises: generating, based on the second connection relationship, tunnel configuration information of a tunnel used to bear traffic between the base stations and/or route diffusion configuration information that is based on a tunnel configuration and that is of a route bearing the traffic between the base stations, wherein the base stations communicate with each other over the bearer network using the corresponding network elements, wherein the network elements are network bearer devices. determining a first correspondence, wherein the first correspondence is a correspondence between geographical location information of the base stations and network element identifiers of the corresponding network elements; obtaining a first connection relationship based on geographical location information of the base stations, wherein the first connection relationship is a connection relationship between the base stations; converting the first connection relationship into a second connection relationship based on the first correspondence, wherein the second connection relationship is a topological connection relationship between the network elements identifiers of the corresponding network elements comprised in the bearer network; and automatically generating a service connection configuration of the bearer network based on the second connection relationship; wherein the converting the first connection relationship into a second connection relationship based on the first correspondence specifically comprises: determining the second connection relationship based on the first correspondence and a second correspondence, wherein the second correspondence is a correspondence between the geographical location information of the base stations and ports of the corresponding network elements; wherein the automatically generating a service connection configuration of the bearer network based on the second connection relationship comprises: generating, based on the second connection relationship, tunnel configuration information of a tunnel used to bear traffic between the base stations and/or route diffusion configuration information that is based on a tunnel configuration and that is of a route bearing the traffic between the base stations, wherein the base stations communicate with each other over the bearer network using the corresponding network elements, wherein the network elements are network bearer devices. determining the second connection relationship based on the first correspondence and a second correspondence, wherein the second correspondence is a correspondence between the geographical location information of the base stations and ports of the corresponding network elements; wherein the automatically generating a service connection configuration of the bearer network based on the second connection relationship comprises: generating, based on the second connection relationship, tunnel configuration information of a tunnel used to bear traffic between the base stations and/or route diffusion configuration information that is based on a tunnel configuration and that is of a route bearing the traffic between the base stations, wherein the base stations communicate with each other over the bearer network using the corresponding network elements, wherein the network elements are network bearer devices.
