可以理解的是，当第一网络连接请求为标准DHCP请求，则网元管理系统根据接收到的网关功能模块的标准DHCP请求后，通过标准DHCP协议响应分配临时地址信息，临时地址信息为DHCP VLAN网络预置分配的网段地址，并返回临时地址信息给网关功能模块，网元管理系统检测临时地址可达后，网元管理系统与网关功能模块建链登录，从而建立网关功能模块与网元管理系统的网络连接。
在一实施例中，网关功能模块接收到临时地址信息，网元管理系统检测临时地址可达后，网元管理系统与网关功能模块建链登录，网元管理系统基于配置数据和脚本模板得到第一网络配置信息和第一正式地址信息，第一正式地址信息包括正式IP地址以及网关掩码，第一网络配置信息包括DHCP Relay和路由配置等配置信息，网关功能模块接收第一网络配置信息和第一正式地址信息，网关功能模块在接收到第一网络配置信息和第一正式地址信息后，开通至网元管理系统的网络平面，使得网关功能模块与网元管理系统通过正式网络平面建立正式网络连接。

需要说明的是，在网元管理系统与网元功能模块建立网络连接后，网元管理系统完成了对网元设备的两级开通，网元管理系统检测第二网络配置信息和管理面地址可达后，网元设备自动接入到网元管理系统中，随后网元管理系统下发业务配置数据到网元设备中，网元设备完成网络的开通连接，当在实际运行环境中，有多个网元设备接入后，网元管理系统对每个网元设备均进行两级开通，从而开通连接其它网元设备。
参照图9所示，本申请实施例提供了一种网元管理系统100(下面称为EMS)，EMS100设置有DHCP Server模块101、北向模块102、接入配置模块103和IUI模块104等，其中，EMS100与网络管理系统300(下面称为NMS)通信连接，上级NMS300下发配置数据给EMS100并接收新接入的网元通知，DHCP Server模块101用于提供标准DHCP服务端能力，验证请求网元设备200的MAC硬件地址，并分配IP地址，该模块也可以单独配置，但是需要有接口和EMS100交互，获取DHCP地址信息，并通知EMS100有设备申请并分配了地址，也可以设置在EMS100内；北向模块102用于接收NMS300的配置数据，提供给DHCP Server模块101和接入配置模块103使用，并在自动接入网元设备200成功后通知NMS300；接入配置用于访问网元设备200并进行网络配置，并在自动接入网元后，下发业务数据配置，完成网元设备200的网络开通连接；I UI模块104可提供web浏览器访问能力，通过客户机400，支持配置数据和脚本模板，查看开通日志以及网元设备200接入通知，管理接入的网元设备200；客户机400为web浏览器，本申请实施例不对其作具体限制。
参照图9所示，网元设备200可以是无线设备和核心网网元设备200，其中，无线设备可以是无线基站210，在无线基站210中，可以进行一级开通连接，本申请实施例以核心网网元设备200为例子，但并不表示为对本申请实施例的限制。在一实施例中，核心网网元设备200包括网关功能模块201以及网元功能模块202，网关功能模块201可以为边缘网关(交 换机)，网关功能模块201以及网元功能模块202可以是分体设置或合一设置。网元设备200需要支持如下能力：DHCP客户端，用于发送DHCP请求，获取配置地址；配置接口，用于完成网元管理网络平面开通和控制网络平面开通配置，网元设备200发送DHCP请求经过承载设备500中继后到达EMS100中。
接下来详述本申请一些实施例的两个场景：

在进行网络开通连接之前，还需要进行前置初始配置，包括：
1)预置DHCP自动发现VLAN网络；
2)EMS预置各类设备开通脚本模板。
下面为图11中的应用步骤，包括：
1、运营商根据设备信息以及规划，在NMS配置开通数据，开通数据信息包括统一的临时IP段；以及按照网元配置的设备类型、设备硬件MAC地址、对应的正式IP以及网关掩码等数据，下发数据至EMS。
2、EMS接收数据并更新存储。
3、如有必要，EMS预置开通脚本模板调整，满足各类设备自动开通，此情况为EMS预置的脚本模板不支持需要接入的网元设备时，才需要执行。
4、网元设备安装上电。
5、边缘网关从预置DHCP VLAN网络发起DHCP请求，经过承载网络DHCP Relay至EMS的DHCP Server模块。

可以理解的是，本申请实施例适用于垂直行业和运营商网络，随着垂直行业采用5G网络与及虚拟化组网，核心网UPF下沉到边缘或者企业园区，网络环境会比较复杂，但垂直行业缺乏专业的通信运维人员，迫切需要降低开通成本，加速行业应用，闭环控制网元从上电到发现和开通连接的过程。所以需要一种能够在复杂网络环境下自动发现和连接网元设备的方法和系统。垂直行业中的一套管理系统不限于EMS统一管理无线和核心网网元设备，自动发现并接入管理和连接，达到快速开通连接的目的，节省人力以及时间成本。在运营商网络中，NMS统一下发开通配置数据，各厂商的管理系统不限于EMS自动发现网元设备并接入管理和 连接。
