动态配置接入终端的实现方法Implementation method of dynamic configuration access terminal

技术领域technical field

本发明涉及网络通信技术领域，尤其涉及一种动态配置接入终端的实现方法。The present invention relates to the technical field of network communication, in particular to a method for realizing dynamic configuration of an access terminal.

背景技术Background technique

随着宽带接入技术的发展，基于宽带IP网络开展的业务也越来越多。通常用户终端为了开通业务，需要预先在终端上配置一些相关的配置参数，如IP地址，网关地址，DNS(域名系统)服务器地址，等。With the development of broadband access technology, more and more services are carried out based on broadband IP network. Usually, in order to open a service, a user terminal needs to configure some relevant configuration parameters on the terminal in advance, such as an IP address, a gateway address, a DNS (Domain Name System) server address, and the like.

用户终端在使用业务之前，需要接入网络，通常的接入方式有两种：PPP(点对点协议)和DHCP(动态主机配置协议)。Before using the service, the user terminal needs to access the network. There are two common access methods: PPP (Point-to-Point Protocol) and DHCP (Dynamic Host Configuration Protocol).

对于PPP接入，如图1所示，用户终端通过接入网连接到PPP服务器，所述的PPP服务器可以为RAS(远程接入服务器)、BRAS(宽带远程接入服务器)、ER(边缘路由器)等设备，PPP服务器用于终结PPP协议，并将用户终端的IP数据报文转发到核心网络。For PPP access, as shown in Figure 1, the user terminal is connected to the PPP server through the access network, and the PPP server can be RAS (Remote Access Server), BRAS (Broadband Remote Access Server), ER (Edge Router ) and other equipment, the PPP server is used to terminate the PPP protocol and forward the IP data packets of the user terminal to the core network.

目前，为了保证用户终端可以获知所述的配置参数信息，采用的是手工配置的方式实现。具体为：在开通业务之前，运营商或用户通过手工配置的方法，将需要的相关的配置参数配置在终端上。At present, in order to ensure that the user terminal can obtain the configuration parameter information, manual configuration is adopted. Specifically, before activating the service, the operator or the user configures the required related configuration parameters on the terminal through a manual configuration method.

显然，如果由运营商手工配置，则运营商的工作量将大大增加，从而将增加其运营成本；而如果由用户配置，则由于配置过程对用户操作能力要求较高，因此，导致极容易出现配置错误的情况，从而影响业务的及时开通。Obviously, if the operator manually configures, the workload of the operator will increase greatly, which will increase its operating cost; and if it is configured by the user, because the configuration process requires high user operation capabilities, it is very easy to cause If the configuration is wrong, it will affect the timely provisioning of services.

目前采用的另一种接入终端的相关配置参数配置方式为：PPP仅作为链路层通道，IP地址及其他配置参数信息由DHCP服务器分配。Another configuration method currently used for configuring relevant configuration parameters of the access terminal is: PPP is only used as a link layer channel, and IP addresses and other configuration parameter information are assigned by a DHCP server.

这种方式可以实现所述配置参数信息的动态配置，但是该方案的实现需要定义PPP承载DHCP的方式，因此，对现有的网络设备改动较大，即需要对设备的软硬件进行升级处理。This method can realize the dynamic configuration of the configuration parameter information, but the implementation of this solution needs to define the way of PPP carrying DHCP, therefore, the existing network equipment needs to be greatly changed, that is, the software and hardware of the equipment need to be upgraded.
