另外, DHCP服务器可以将 DHCP服务器标识发送给 DHCP客户机,
DHCP客户机根据该标识对 DHCP服务器进行认证, 认证通过后, 才使用其 分配的传输参数。
下面结合附图及具体实施例对本发明进行详细说明。
如图 1所示, 本发明实施例的装置包括 DHCP客户机和 DHCP服务器, 所述 DHCP客户机设置成将其设备标识上报给 DHCP服务器, 并根据
DHCP服务器发送的传输参数进行自配置、 自建立; 所述 DHCP服务器设置 成根据所述设备标识为所述 DHCP客户机配置传输参数,并下发给所述 DHCP 客户机。
所述 DHCP客户机还设置成设置信任的 DHCP服务器标识, 以及, 根据 接收到的 DHCP服务器标识进行认证, 若属于信任的 DHCP服务器标识, 才 使用所述传输参数进行自配置; 所述 DHCP服务器还设置成将所述传输参数 下发给 DHCP客户机时, 还将自身的标识发送给所述 DHCP客户机。 在本实施例中 , DHCP客户机是为满足特殊需求而设计的 DHCP客户机, 包括可以对 DHCP服务器简单认证, 可以识别并利用 DHCP服务器通过 DHCP报文选项(option )字段下发的数据信息; DHCP服务器在满足可配置 自身的标识信息, 并针对 DHCP客户机上报的设备标识配置 DHCP报文选项 字段值的情况下, 不需要特殊设计。
如图 1所示, DHCP客户机 a~c上报其设备标识可以釆用广播的方式, DHCP服务器 A~B均会收到上报的设备标识; DHCP服务器 A~B根据接收 到的设备标识查表判断是否需要分配传输参数, 若需要, 则将分配的传输参 数发送给相应的 DHCP客户机; 而 DHCP客户机也可以根据接收到的 DHCP 服务器标识对 DHCP服务器进行认证。
如图 2所示, 本发明实施例实现静态分配 IP的过程, 要求设备具有唯一 设备标识, 具体的步骤如下:
步骤 201 , DHCP客户机设置信任的 DHCP服务器标识;

步骤 204, DHCP服务器根据 DHCP客户机提供的设备标识, 查找标识 和传输参数的对应表分配该客户机的 IP地址, 构造 DHCP报文, 在报文中携 带该客户机的 IP地址和自身的标识, 发送给 DHCP客户机; 在本步骤中, 若 DHCP服务器查找对应表失败, 则丟弃该 DHCP客户机 发送的报文, 不再执行后续步骤;

若 DHCP服务器可分配固定 IP地址, 则可在 DHCP OFFER报文正文中 携带客户机的 IP地址; 若釆用通用的 DHCP服务器, 由于其使用的是地址池 管理, 不能分配固定的 IP给 DHCP客户机, 则 DHCP服务器可使用 DHCP OFFER报文中 option 41 ( NIS )携带分配的 IP地址;
步骤 205, DHCP客户机解析 DHCP服务器标识, 如果是该客户机信任 的服务器, 则进行根据接收到的传输参数进行自配置、 自建立;
在本步骤中, 若 DHCP客户机根据 DHCP服务器标识判断是该客户机信 任的服务器, 则发送 DHCP INFORM报文给 DHCP服务器, 确认 IP地址已 占用, DHCP服务器接收到 DHCP INFORM才艮文后给客户机返回 ACK; 如果 DHCP客户机根据 DHCP服务器标识判断是非信任的服务器,则丟弃该 DHCP OFFER报文。
下面以一具体应用示例进一步对本发明进行说明:

步骤 308 , LTE基站收到回应后配置自身参数, 向 MME发起 SCTP建链 请求, 完成传输自建立。
综上所述, 本发明提出了一种 DHCP实现 IP静态分配的方法及其装置, 该 方法及装置适合特定设备需要分配固定 IP的场景, 特别适用于 LTE基站 SON 需求的传输自建立。
当然, 本发明还可有其它多种实施例, 在不背离本发明精神及其实质的 但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
工业实用性
与现有技术相比, 本发明提供的自组织网络传输自配置的方法和装置具 有很强的可维护性。
