5401、 核心网设备产生第一消息发送给接入控制器; 相应的, 接 入控制器接收来自核心网设备的第一消息。
5402、 根据所述第一消息生成第一语音控制数字信号。 其中, 若所述第一消息为用于表示被叫用户已经在振铃的消息, 则 所述第一语音控制数字信号为向主叫用户放回铃音数字信号; 或者, 若所述第一消息为用于表示被叫用户已经摘机的消息,则所述第一 语音控制数字信号为向主叫用户停放回铃音数字信号; 或者, 若所述第一消息为用于寻呼被叫的消息,则所述第一语音控制数字 信号为被叫用户振铃数字信号。
示例的, 4艮设通信终端为电话机, 当电话机处于主叫呼叫状态时 , 即电话机为主叫用户时, 若 IMS Core产生 180消息发送给接入控制器, 此时, 第一消息为 180消息; 接入控制器根据接收到的 180消息, 得知 被叫用户已经振铃, 则生成主叫用户放回铃音的数字信号, 即第一语音 控制数字信号为主叫用户放回铃音的数字信号; 若 IMS Core产生 200 消息发送给接入控制器, 此时, 第一消息为 200消息; 接入控制器根据 接收到的 200消息,得知被叫用户已经摘机, 则生成主叫用户停放回铃 音的数字信号,即第一语音控制数字信号为主叫用户停放回铃音的数字 信号。

Drop/Distribution Point ) /FTTH (光乡千 J分西己 、, Fibre to the Home ) 场景下的应用意义非常重大, 因为在 FTTDP/FTTH场景下, 远端节点的 数量与家庭用户的数量在同一个数量级,如果对每个物理接入节点进行 IP地址的管理, 那么管理 IP地址的数量非常巨大, 运维成本也相对增 加, 通过对 AG管理面的上移, 将多个接入网关虚拟化为一个大的接入 网关进行管理, 可以简化管理的数量, 运维成本也随之降低。
