) , RE4为第 0级 RE , 即级数 HOP=0。
其中, 每一级 RE与 REC的上层链路直接相连, 每一级 RE的底层链路, 依次经由前面各级 RE与 REC相连。
当 REC获知与串行级联总线上的某一 RE的上层链路, 例如: HDLC、 LAPD或以太网的链路断开时 , REC可以通过与该 RE连接的端口向该 RE发 送复位指示, REC可以在底层链路上采用 CPRI协议向 RE发送复位指示。该 复位指示中可以携带复位标识和该 RE的设备标识, 复位标识用于指示该 RE 进行复位操作, 具体可以指示 RE进行软复位操作或者掉电复位操作, 具体 的: 软复位是指, 在设备不断电的情况下对设备进行重新启动。 掉电复位是 指切断设备的电源, 待设备重新接通电源后, 对设备进行重新启动。
设备标识可以是该 RE的 HOP号, 例如: REC与 RE2之间的上层链路
断开, 则 REC可以在端口 0上向 RE2发送复位指示, 复位指示中携带 RE2 的设备标识 HOP=2,该复位指示分别经过 RE0和 RE1的底层链路透传给 RE2。 其中, RE0和 RE1判断出复位指示中的设备标识不是自身的设备标识, 则向 下一级 RE传递该复位指示。 RE2收到复位指示后, 判断出复位指示中的设 备标识是自身的设备标识,则根据复位指示中的复位标识进行复位操作, RE2 复位后, 从而与 REC之间的上层链路重新建立连接。
需要说明的是, 图 2提供的串行级联总线上的分布式通信设备的结构示 意图中, REC和端口 0上的多个 RE采用链式连接方式, 实际上, REC和端 口上的多个 RE 还可以采用星型链接方式, 或者环型链接方式, 而无论采用 哪种连接方式, REC的每个端口上串行级联的 RE都具有唯一的级数 HOP号, 因此, 通过 HOP号能够在 REC的任一端口上唯一确定一个 RE, 因此, 无论 REC和端口上的各个 RE采用何种链接方式, 都适用于本发明提供的串行级 联射频设备的复位方法。
本发明实施例提供的串行级联射频设备的复位方法, 射频设备控制器向 射频设备发送的复位指示中包括复位标识和该射频设备的设备标识, 使得射 频设备控制器能够对串行级联总线上链路断开的射频设备进行复位, 而其余 射频设备无需进行复位, 避免中断链路正常的 RE 的业务, 保证链路正常的 RE的工作。
图 3为本发明提供的串行级联射频设备的复位方法又一个实施例的流程 图, 如图 3所示, 该方法包括:
S201、 获取射频设备的链路中断信息;
S202、通过与所述射频设备连接的端口向所述射频设备发送的复位指示, 所述复位指示中包括复位标识和所述射频设备的设备标识, 以使所述射频设 备根据所述复位标识和所述设备标识进行复位。
以上步骤的执行主体为串行级联总线上的射频设备控制器 REC。
参见图 2, 当 REC获知与串行级联总线上的某一 RE的上层链路断开时,
REC可以通过与该 RE连接的端口向该 RE发送复位指示, REC可以在底层链路 上采用 CPRI协议向该 RE发送复位指示,该复位指示中可以携带复位标识和该 RE的设备标识, 复位标识可以用于指示该 RE进行软复位操作, 也可以用于指 示该 RE进行掉电复位操作。 具体的: 软复位是指, 在设备不断电的情况下对 设备进行重新启动。 掉电复位是指切断设备的电源, 待设备重新接通电源后, 对设备进行重新启动。 设备标识可以是该 RE的 HOP号, 例如: REC与 RE2之 间的上层链路断开, 则 REC可以在端口 0上向 RE2发送复位指示, 复位指示中 携带 RE2的设备标识 HOP=2, 该复位指示分别经过 RE0和 RE1的底层链路透传 给 RE2。其中, RE0和 RE1判断出复位指示中的设备标识不是自身的设备标识, 则向下一级 RE传递该复位指示。 RE2收到复位指示后, 判断出复位指示中的 设备标识是自身的设备标识, 则根据复位指示中的复位标识进行复位操作, RE2复位后, 从而与 REC之间的上层链路重新建立连接。
本发明实施例提供的串行级联射频设备的复位方法, 射频设备控制器向 射频设备发送的复位指示中包括复位标识和该射频设备的设备标识, 使得射 频设备控制器能够对串行级联总线上链路断开的射频设备进行复位, 而其余 射频设备无需进行复位,避免中断链路正常的 RE的业务, 保证链路正常的 RE 的工作。
本发明提供的串行级联射频设备的复位方法另一个实施例中, 作为一种 较佳的实施方式, REC获取射频设备的链路中断信息后, 还可以对该 RE与 REC连接的 REC端口上的所有设备进行复位。 具体的:
REC可以向该端口上的第一级 RE发送复位指示, 该复位指示中携带复 位标识和全复位标识, 该全复位标识用于指示与所述射频设备控制器连接的 端口上的所有射频设备进行复位, 其中, 该全复位标识可以是预先定义的一 个标识号, 例如: 可以定义为 Oxff, 该端口上的第一级 RE接收到该复位指示 后, 识别出设备标识为全复位标识, 则可以在自身进行复位操作之前, 或者 在自身进行复位操作之后, 将该复位指示发送给下一级 RE, 以使下一级设备
根据该复位指示进行复位操作。 该端口上的每个 RE在获取复位指示后, 都 将该复位指示信息发送给下一级设备, 从而使该端口上的每个 RE都进行复 位操作。
或者, REC还可以向该端口上的所有 RE发送复位指示, 该复位指示信息 中包括复位标识和该端口上连接的所有 RE的全复位标识, 即 REC可以以广播 的方式向该端口上的所有 RE发送复位指示,每个 RE接收到该复位指示后, 都 根据复位标识进行复位操作。
其中, 复位指示信息可以采用 CPRI协议实现, 本发明实施例仅是以 CPRI 协议为例进行说明, 可以理解的是, 还可以采用其他协议实现。
现有的 CPRI协议的控制字段定义如下:
其中, HOP字段的下行为 HOP+l , 上行为 ΗΟΡ^。
由于现有的 CPRI协议的控制字段只支持软复位的方式,而由于 RE上的某 些器件的软复位无法恢复该器件的正常运行, 必须掉电复位才能保证器件的 正常工作, 因此, 本发明提供的实施例, 可以在 CPRI协议的控制字段中增加
掉电指示复位功能, 即复位指示中的复位标识可以为软复位(Software Reset ) 或者掉电复位(Power Off) , 以保证 RE上的所有器件均能够恢复正常工作, 而复位指示中的设备标识(可以为 RE的级数号或者是端口上所有 RE的全复位 标识), 可以通过修改原 CPRI控制字段中的 Hop Number的方式来实现。 本发 明提供的 CPRI协议的控制字段定义如下:
另外, 需要说明的是, 如果 REC发送的复位指示中指示某一端口上级联 的所有 RE均进行掉电复位, 考虑到如果其中某一级 RE掉电, 则 REC与该 RE后面的各级 RE的物理链路将断链, 那么该 RE后面各级 RE将无法获取 复位指示。 因此, 如果复位标识为掉电标识, 则接收到复位指示的 RE 可以 设定延迟时间, 在延迟时间到达后进行掉电复位, 延迟时间可以根据具体情 况或需要来设定, 例如: 可以设置为 lms, 也可以设置 Is的延迟时间, 以确 保该端口上的所有 RE均能够获取复位指示。
程, 是可以通过计算机程序来指令相关的硬件来完成, 所述的程序可存储于 一计算机可读取存储介质中, 该程序在执行时, 可包括如上述各方法的实施 例的流程。其中,所述的存储介质可为磁碟、光盘、只读存储记忆体( Read-Only Memory, ROM )或随机存者 i己忆体 ( Random Access Memory, RAM )等。

参见图 2, 当 REC获知与串行级联总线上的某一 RE的上层链路, 例如: HDLC、 LAPD或以太网的链路断开时, REC可以通过与该 RE连接的端口向 该 RE发送复位指示, REC可以在底层链路上采用 CPRI协议向 RE发送复位 指示。 该复位指示中可以携带复位标识和该 RE 的设备标识, 复位标识用于 指示该 RE进行复位操作,具体可以指示 RE进行软复位操作或者掉电复位操 作, 设备标识可以是该 RE的 HOP号, 例如: REC与 RE2之间的上层链路 断开, 则 REC可以在端口 0上向 RE2发送复位指示, 复位指示中携带 RE2 的设备标识 HOP=2,该复位指示分别经过 RE0和 RE1的底层链路透传给 RE2。
当 RE0和 RE 1的获取单元 11获取到复位指示后, 判断出复位指示中的 设备标识不是自身的设备标识, 则向下一级 RE传递该复位指示。 RE2的获 取单元 11获取到复位指示后,判断出复位指示中的设备标识是自身的设备标 识,则复位单元 12根据复位指示中的复位标识和设备标识进行复位操作, RE2 复位后, 与 REC之间的上层链路重新建立连接。

发送单元 13 , 用于将所述复位指示发送与所述射频设备控制器连接的端 口上的下一级射频设备。
进一步的, 若复位标识为掉电复位标识, 且设备标识为全复位标识, 则 该射频设备还可以包括:
延迟单元 14, 用于设置延迟时间;
相应的, 复位单元 12具体用于: 在所述延迟单元 14设置的所述延时时 间到达后进行掉电复位, 以使与所述射频设备控制器连接的端口上的所有射 频设备获取所述复位指示。
获取单元 11获取到的设备标识可以为与 REC连接端口上所有 RE的标 识, 即 REC可以指示某端口上级联的所有 RE进行复位。 具体的, REC可以 向该端口上的第一级 RE发送复位指示, 该复位指示中携带复位标识和该端 口上连接的所有 RE的全复位标识,该端口上的第一级 RE接收到该复位指示 后, 识别出设备标识为全复位标识, 则可以在自身进行复位操作之前, 或者 在自身进行复位操作之后, 将该复位指示发送给下一级 RE, 以使下一级设备 根据该复位指示进行复位操作。 该端口上的每个 RE的获取单元 11获取复位 指示后, 发送单元 13都将该复位指示信息发送给下一级设备, 从而使该端口 上的每个 RE的复位单元 12都进行复位操作。
或者, REC还可以向该端口上的所有 RE发送复位指示, 该复位指示信 息中包括复位标识和该端口上连接的所有 RE的全复位标识 , 即 REC可以以 广播的方式向该端口上的所有 RE发送复位指示, 每个 RE的获取单元 11接
收到该复位指示后, 复位单元 12都可以根据复位标识进行复位操作。
另夕卜,需要说明的是,如果获取单元 11获取的复位指示为掉电复位指示, 并且设备标识为全复位标识, 即 REC指示某一端口上级联的所有 RE均进行 掉电复位, 考虑到如果其中某一级 RE掉电, 则 REC与该 RE后面的各级 RE 的物理链路将断链, 那么该 RE后面各级 RE将无法获取复位指示。 因此, 如 果复位标识为掉电标识, 则 RE可以通过延迟单元 14设置延迟时间, 复位单 元 12可以在延迟时间到达后进行掉电复位, 延迟单元 14可以根据具体情况 或需要来设定延迟时间, 例如: 可以设置为 1ms,也可以设置 Is的延迟时间, 以确保该端口上的所有 RE均能够获取复位指示。
