Description

一种获取地址的方法和装置Method and device for obtaining address 技术领域Technical field

本文涉及但不限于动态主机配置协议(DHCP，Dynamic Host Configuration Protocol)技术，尤指一种获取地址的方法和装置。This document relates to, but is not limited to, Dynamic Host Configuration Protocol (DHCP) technology, and more particularly to a method and apparatus for obtaining an address.

背景技术Background technique

为了防止家庭网关无线覆盖信号弱导致下挂的终端无法上网的情况，会通过在家庭网关和下挂的终端之间添加无线中继器(Repeater)来增强无线信号。图1为家庭网关与Repeater对接的组网示意图。如图1所示，家庭网关和Repeater之间通过无线方式相连，Repeater和移动终端之间通过无线方式相连，Repeater和笔记本之间通过无线方式相连，Repeater和个人电脑(PC，Personal Computer)之间通过有线方式相连。这种组网结构下，移动终端、笔记本和PC等需要获取家庭网关为其分配的地址，以实现通信。In order to prevent the downlink terminal from being unable to access the Internet due to the weak wireless coverage signal of the home gateway, the wireless signal is enhanced by adding a wireless repeater between the home gateway and the connected terminal. FIG. 1 is a schematic diagram of networking of a home gateway and a Repeater. As shown in FIG. 1, the home gateway and the Repeater are connected by wireless, the Repeater and the mobile terminal are connected by wireless, the Repeater and the notebook are connected by wireless, and between the Repeater and the personal computer (PC, Personal Computer). Connected by wire. In this networking structure, mobile terminals, notebooks, and PCs need to obtain an address assigned by the home gateway to implement communication.

图2为相关的获取地址的方法的流程图。如图2所示，该方法大致包括：2 is a flow chart of a related method of obtaining an address. As shown in Figure 2, the method generally includes:

终端向Repeater发送发现(DISCOVER)报文，Repeater将接收到的DISCOVER报文的源媒体访问控制(MAC，Media Access Control)地址改为自身的MAC地址后转发给家庭网关；支持引导程序协议(BOOTP，Bootstrap Protocol)的家庭网关向Repeater发送提供(OFFER)报文，OFFER报文中包含有分配给终端的互联网协议(IP，Internet Protocol)地址，Repeater将OFFER报文转发给终端；终端向Repeater发送请求(REQUEST)报文，Repeater向家庭网关转发REQUEST报文；家庭网关向Repeater发送确认字符(ACK，Acknowledgement)，Repeater向终端转发ACK。The terminal sends a DISCOVER packet to the Repeater. The Repeater forwards the source media access control (MAC, Media Access Control) address of the received DISCOVER packet to its own MAC address and forwards it to the home gateway. Supports the bootstrap protocol (BOOTP). The home gateway of the Bootstrap Protocol sends an OFFER message to the Repeater. The OFFER message includes an Internet Protocol (IP) address assigned to the terminal, and the Repeater forwards the OFFER message to the terminal; the terminal sends the OFFER message to the Repeater. The request (REQUEST) message, the Repeater forwards the REQUEST message to the home gateway; the home gateway sends an acknowledgement character (ACK, Acknowledgement) to the Repeater, and the Repeater forwards the ACK to the terminal.

其中，不支持BOOTP的家庭网关接收到DISCOVER报文后，会检测DISCOVER报文中的源MAC地址和DISCOVER报文内部与MAC地址相关的信息是否相匹配，如果匹配，则向Repeater发送OFFER报文；如果不匹配，则不发送OFFER报文，从而终端无法获得家庭网关分配的IP地址。终端在预设时间内接收不到OFFER报文时，重新向Repeater发送DISCOVER报文。After receiving the DISCOVER packet, the home gateway that does not support BOOTP detects whether the source MAC address in the DISCOVER packet and the information related to the MAC address in the DISCOVER packet match. If the match is matched, the OFFER packet is sent to the Repeater. If there is no match, the OFFER message is not sent, so the terminal cannot obtain the IP address assigned by the home gateway. When the terminal does not receive the OFFER message within the preset time, it sends a DISCOVER message to the Repeater again.

相关的获取地址的方法中，由于终端和Repeater并不知道家庭网关是否 支持BOOTP，存在不能获取地址的问题，因此降低了获取地址的成功率。In the related method of obtaining an address, since the terminal and the Repeater do not know whether the home gateway is Support for BOOTP, there is a problem that the address cannot be obtained, thus reducing the success rate of obtaining the address.
