具体地, 在实现时, 可以在家庭网关上利用 xDSL链路数据帧中的一个 嵌入操作信道(EOC )上传预先定义的标志信息, 利用现有的网络体系就可 以实现该功能。 由于嵌入操作信道(EOC )是 xDSL链路数据帧中的一个通 道, 只要 xDSL链路同步, xDSL终端上的特定信息就会通过嵌入操作信道 ( EOC )传到网络侧设备, 网络侧在业务开展前就可以对设备进行控制, 从 而可以有效解决对 xDSL终端的接入控制。
基于上述思想, 本发明提供了一种控制 xDSL终端接入网络的方法, 该 方法釆用以下技术方案:
支持 xDSL接入的家庭网关配置嵌入操作信道(EOC )标识信息, 并在 xDSL终端请求接入网络时, 将 EOC标识信息上 4艮到网络侧;
网络侧根据上报的 EOC标识信息对 xDSL终端进行识别,若识别出 xDSL 终端是本网络的 xDSL终端, 则允许 xDSL终端接入网络, 否则, 拒绝 xDSL 终端接入网络。
其中, 家庭网关可以支持自己配置, 也可以支持远程网管下发配置, 即 家庭网关可以通过本地或远程配置方式配置 EOC标识信息。
进一步地, 本地配置指从本地数据库读取或本地 GUI配置; 远程配置是 指网络侧为家庭网关配置 EOC标识信息并下发给家庭网关。
进一步地, 上述方法具体可分为以下步骤:
步骤 A, xDSL终端通过本地或远程配置方式配置嵌入操作信道 ( EOC ) 标识信息;
步骤 B, xDSL终端通过 xDSL链路同步链路, 上报 EOC标识信息到数 字用户线路接入复用器(DSLAM ) ;
步骤 C, 宽带接入服务器获取 DSLAM线路上的 EOC信息, 对线路上的 xDSL终端进行接入控制;
步骤 D,家庭网关进行业务接入,宽带接入服务器根据 EOC信息对 xDSL 终端进行识别和裁决, 如果 xDSL终端是本网络的 xDSL终端, 则允许 xDSL 终端接入网络, 否则, 不允许 xDSL终端接入网络。
进一步地, 所述方法还包括: xDSL终端接入网络后 , 网络侧可以对 xDSL终端当前的 EOC标识信息 进行修改, 并下发给家庭网关;
家庭网关根据网络侧下发的 EOC标识信息重新进行链路同步。
例如,家庭网关可以通过网管服务器修改预先定义的 EOC标识信息来解 锁业务。 xDSL终端注册到网管服务器后, 通过远程网管服务器下发 EoC标 识信息给 xDSL终端, xDSL终端保存该 EOC标识信息, 重启 xDSL链路协 商。 从而, 根据下发的标识信息, 可以使 xDSL终端动态获取更多业务, 既 保证了对 xDSL终端的接入控制, 又保证了接入网络的灵活性。
