Description

射频旁路切换控制方法、 系统和射频控制器 技术领域
本发明实施例涉及通信技术领域， 尤其涉及一种射频旁路切换控制方 法、 系统和射频控制器。 背景技术
现有基站通过射频拉远实现了广覆盖和节约基带成本。 基带使用光纤 与拉远射频单元相连， 一个拉远射频单元可外接两根光纤， 支持串联和环 接， 在现有基带与射频组网的结构中， 基带与射频之间的通过高级数据链 路控制 （ High level Data Link Control; 简称： HDLC ) 和公共通用无线接 口 ( Common Public Radio Interface; 简称： CPRI )协议实现数据交换。 基 带部分主要负责对射频单元进行探测、 建链、 操作维护， 称为射频控制器 ( Radio Equipment Control; 简称： REC ) ； 射频单元在从属被管理地位， 称为射频设备（Radio Equipment; 简称： RE ) 。 按照 CRPI协议， REC可 以根据探测到的跳数（HOP ) 确定 RE的物理连接形态， 据此分辨出各个 RE, 并进行有针对性的配置维护； RE 也可以获知自身的 HOP, 在建立 HDLC链路时使用。
当 RE被环接时， 其上联光口的 HOP为 "0" , 下联光口为无效值， 其 中， RE的哪个物理光口为上联光口由 CPRI扫描竟争决定， 也存在两侧光口 HOP均为 "0" 的特殊场景。 与环接相比， RE串联节省光纤， 但 RE串联的 组网可靠性稍差， RE 串联的链中的 RE掉电或光纤松脱都会导致链尾的 RE 停工。 旁路切换是指： 某一 RE掉电后， 可以将该 RE的两个光口内部自动短 接， 使该 RE上联光口的物理层数据可以透传到下联光口， 不影响下一级 RE 的通讯链路。
旁路切换可以提升 RE串联网络的链路可靠性（光纤松脱情况不考虑） ， 但是， RE掉电后链路透传的同时 HOP也被透传， 后继 RE HOP比被旁路前 减小了 "1" 。 RE旁路与否， 对于 REC而言， 除了总 HOP变化以外， 没有 更多的提示， REC无法获知第几级的 RE被旁路。 假设原有三个物理 RE, 如 果第二级 RE旁路切换， 认为串联组网中只有两个物理 RE , 第三级 RE被当 成了原来的第二级 RE使用， REC向第三级 RE下发原来的第二级 RE的配置 数据， 导致第三级 RE虽然物理层 HDLC链路可用， 却无法按照正确的配置 工作。
每个具有全球唯一的硬件序列号， REC可以通过 HDLC广播查得 CPRI 网络内每个 RE的序列号和跳数。 REC可以通过 RE的序列号对 RE进行精确 管理。 如果 RE串联网络中段的 RE被旁路， 后续 RE的跳数虽然改变， 但序 列号不变， 对配置维护不产生任何影响。
但是， 采用 RE的序列号进行配置维护， 网络规划人员需要将大量 RE的 序列号全部查出， 并事先规划每个 RE的放置位置， 开站前工作量巨大。 发明内容

图 1为本发明实施例一提供的射频旁路切换控制方法的流程图， 如图
1所示， 该射频旁路切换控制方法可以包括：
步骤 101、 射频控制器将串联组网的各个射频设备的跳数进行锁定； 具体地， 基站（其中包括射频设备和射频控制器等） 的运行环境按工 作场景可分为两类： 开站、 扩容、 调测等集中运维阶段， 以及偶尔运维或 不运维的稳定运行阶段。 集中运维阶段持续时间短， 通常以小时计， 射频 设备（RE )的安装更换均在集中运维阶段进行， 在集中运维阶段， 射频控 制器 （REC ) 可以对 RE的跳数（HOP ) 进行探测， 解决各种异常情况， 以获得 RE 正确的跳数。 稳定运行阶段持续时间长， 可以以年月计， RE 掉电、 旁路切换等异常集中在稳定运行阶段， 并且， 在稳定运行阶段 RE 的物理设备一般不会被更换，即使 REC对 RE的探测出跳数变化也不对物 理的 RE进行更换。 为方便理解， 本发明实施例将集中运维阶段 REC对 RE的跳数进行探测称为跳数探测模式， 在稳定运行阶段， REC锁定跳数， 根据锁定后的跳数对 RE进行管理称为跳数（HOP ) 锁定模式。 如果需要 由稳定运行阶段进入集中运维阶段， 上层系统可以向 REC发送探测模式 切换命令， 若 REC接收到探测模式切换命令， 则可以将串联组网的射频 设备从跳数锁定模式切换为跳数探测模式。 如果需要由集中运维阶段进入 稳定运行阶段， 上层系统可以向 REC发送锁定模式切换命令， REC收到 锁定模式切换命令后， 可以将串联组网的射频设备从跳数探测模式切换为 跳数锁定模式。其中，从跳数探测模式切换到跳数锁定模式的过程中， REC 需要对各个 RE的跳数进行探测， 然后将探测到的 RE的跳数进行锁定。 因此， 在执行步骤 101之前， 该射频旁路切换控制方法还可以包括： 通过高级数据链路控制广播按照设定周期向各个射频设备发起跳数 探测；
根据探测到的各个射频设备的跳数， 向各个射频设备下发配置数据； 以及根据探测到的各个射频设备的跳数， 建立各个射频设备的高级数据链 路控制通道。
在步骤 101中， 射频控制器将串联组网的各个射频设备的跳数进行锁 定的步骤具体可以包括：
射频控制器将探测到的各个射频设备的跳数保存为锁定后的跳数； 号。
步骤 102、 若有射频设备发生旁路， 则所述射频控制器根据锁定后的 跳数， 向未发生旁路切换的射频设备下发对应的配置数据。
其中， 射频控制器根据锁定后的跳数， 向未发生旁路切换的射频设备 下发对应的配置数据的具体过程可以包括：
发起高级数据链路控制广播， 获取所述未发生旁路切换的射频设备的 序列号， 并确定对应的锁定后的序列号；
根据查找到的锁定后的序列号查找对应的锁定后的跳数；
根据查找到的锁定后的跳数， 向所述未发生旁路切换的射频设备下发 对应的配置数据， 例如： 如天线的倾角、 发射的功率等工作参数。
进一步地， 在射频设备发生旁路之后， 该射频旁路切换控制方法还可 以包括建立链路的过程， 具体为：
根据高级数据链路控制 （HDLC ) 广播， 按照设定周期获取所述未发 生旁路切换的射频设备的实时跳数；
根据所述未发生旁路切换的射频设备的实时跳数， 建立所述未发生旁 路切换的射频设备的高级数据链路控制通道。
进一步地， 在射频设备发生旁路之后， 该射频旁路切换控制方法还可 以包括确定发生旁路切换的射频设备的过程， 具体为：
根据高级数据链路控制广播， 按照设定周期获取所述未发生旁路切换 的射频设备的实时跳数（即可以获取旁路切换后的射频设备的实时跳数）； 根据所述未发生旁路切换的射频设备锁定后的跳数与所述未发生旁 路切换的射频设备的实时跳数， 确定发生旁路切换的射频设备。
本实施例射频控制器可以将串联组网的各个射频设备的跳数进行锁 定， 当某个射频设备遭遇异常掉电导致射频设备自动旁路切换时， 射频控 制器可以根据锁定后的跳数， 向未发生旁路切换的射频设备下发对应的配 置数据， 可以保证未发生旁路切换的射频设备按锁定前的配置和状态工 作， 从而提升射频单元串联组网的可靠性； 并且射频控制器根据未发生旁 路切换的射频设备锁定后跳数和未发生旁路切换的射频设备的实时跳数 可以识别出发生旁路的具体射频设备， 方便维护。
实施例二
图 2为本发明实施例二提供的射频旁路切换控制方法的流程图， 如图 2所示， 在实施例一的基础上， 该射频旁路切换控制方法具体可以包括： 步骤 201、 REC可以默认在 HOP探测模式， 在集中运维阶段， REC 按照设定周期向 RE发起 HOP探测并保存探测结果，探测结果可以包括在 HOP探测模式的 RE的跳数， 一般为正常工作时的跳数；
步骤 202、 REC按照设定周期向 RE发起 HDLC广播以获取和保存各 个 RE的序列号。该 RE的序列号在该步骤可以不用于 HDLC的建链判定， 而作为业务辅助数据管理； 步骤 201与步骤 202可以同时执行， 可以先执 行步骤 201再执行步骤 202, 也可以先执行步骤 202再执行步骤 201。
步骤 203、 REC基于 HOP探测模式的跳数可以识别物理的 RE,为 RE 建立 HDLC通道， 并将对应的配置数据下发到 RE。
步骤 204、 基站运维人员开站完成， 或用户安装完成、 运维结束后， 在很长一段时间基站的 REC和 RE稳定工作，需要从集中运维阶段进入稳 定运行阶段， 上层系统可以通过锁定模式切换命令通知 REC 进行模式切 换， REC 收到锁定模式切换命令后， 可以将所有串联组网的 RE 切换为 HOP锁定模式。 而所有环型组网的 RE仍保持跳数探测模式， 环型组网的 RE可以通过倒换来提高链路稳定性， 无需使用旁路切换。
步骤 205、 REC将探测到的每个 RE从 HOP探测模式切换到 HOP锁 定模式时的 HOP保存为 "锁定后的 HOP" 、 序列号保存为 "锁定后的序 列号" 。 其中， "锁定后的 HOP" 、 "锁定后的序列号" 可以存为只读文 件， 不允许 HOP锁定模式的 RE修改， 以保证在稳定运行阶段 REC即使 复位重启， 也可以继续沿用前一次锁定的数据。 另外， REC也可以通知串 联组网中的每个 RE,禁止串联组网中的每个 RE在发现自身跳数变化后主 动复位， 保证前级 RE旁路不影响后继 RE继续工作；
步骤 206、 REC继续发起 HDLC广播， 得到的 RE在 HOP锁定模式 的序列号不再作为辅助数据， 而作为用户定位 RE的物理位置， 将获取的 序列号在 "锁定后的序列号"中查找匹配，正常情况下都能匹配到某个 "锁 定后的序列号" 。 如果无匹配项则表示维护人员接入了新的 RE, REC可 以不继续处理。
步骤 207、 REC查找到 "锁定后的序列号" 后， 根据查找到的 "锁定 后的序列号" 查找到与之对应的 "锁定后的 HOP" ；
步骤 208、 REC查找到 "锁定后的 HOP" 后， 再与 HDLC广播中携 带的 HOP锁定模式的 RE的 "实时 HOP" 进行比较； 如果在串联组网中 的某个 RE遭遇异常掉电， RE的硬件自动旁路切换， 此时， 发生旁路切换 的 RE及其后继 RE的 "实时 HOP" 与 "锁定后的 HOP" 不同。 REC可以 识别发生旁路切换的 RE具体是哪一个 RE。
步骤 209、 REC采用 "锁定后的 HOP" 与用户配置进行核对， 得到未 发生旁路切换的 RE在锁定前的配置， 从而保证未发生旁路切换的 RE可 以按照锁定前的配置和状态正常工作； 例如： 锁定前的配置与物理对应关系如下： 串联组网的链上第一级
RE驻波门限是 " 1.5" ， 第二级 RE驻波门限是 " 1.8" ， 第三级 RE驻波 门限是 "2.0" 。 锁定后即使第二级 RE旁路， 第三级 RE还可以按 "2.0" 的配置驻波门限工作， 不会被 REC认作第二级从而将其驻波门限误切换 成 " 1.8" 。
步骤 210、 REC基于实时探测到的 RE的 "实时 HOP" (在步骤 208 时获得） ， 建立 RE在 HOP锁定模式的 HDLC通道。
在稳定运行阶段， 串联组网的 RE处于 HOP锁定模式， REC依然周 期探测各个 RE的 HOP, 但得到的 RE的实时 HOP不用于 HDLC建链 /拆 链的判定， 而可以用于旁路切换告警， 当某一级 RE被旁路切换后总 HOP 减少时， 外部用户可通过 "HOP不一致" 告警感知 RE的异常， 进而安排 人员排障。
例如： 用户配置一个 3级串联 RE网络， 第一级到第三级 RE的驻波 门限分别是 " 1.5" 、 " 1.8" 、 "2.0" ； 物理上接入三个 RE, 其 HOP分 别为 "0" 、 " 1" 、 "2" , 序列号分别是 "AA" 、 "BB" 、 "CC" 。 锁定模式下中间位置的 RE掉电后硬件旁路， 此时， 如果 REC的首先探测 到物理的 RE从三个变成为两个， 可以设置用户告警， 同时通过拓朴扫描 过程例如： REC发起 HDLC广播， 可以感知到锁定后的序列号为 "AA" 和 "CC"的两个 RE的物理设备都存在，且其实时 HOP分别是 "0"和 " 1" 。 REC在锁定数据表中可以查出锁定后的序列号为 "AA" 和 "CC" 的 RE 对应的锁定后的 HOP分别是 "0" 和 "2" , 进而查到锁定后的序列号为 "AA" 和 "CC" 的 RE使用的驻波门限分别是 " 1.5" 和 "2.0" 。 由于锁 定后的序列号和锁定后的 HOP在稳定运行阶段为只读数据， 不发生改变， 所以即使 REC重启， 也可以按照前次的锁定状态正常配置 RE。
进一步地， 本发明实施例可以不用在每次更换 RE都更改 RE的配置， 当运维人员需要再次进站准备扩容时， 可以先解除锁定模式， 例如： 通过 上层系统向 REC发送探测模式切换命令， 指示 REC将串联组网的 RE从 HOP锁定模式切换为 HOP探测模式， 然后再调整物理 RE连接， 施工完 成后， 重新执行步骤 201恢复锁定模式即可。
本实施例 REC可以将串联组网中的各个 RE的跳数进行锁定， 当某个 RE遭遇异常掉电导致 RE 自动旁路切换时， REC可以根据 RE在 HOP探 测模式的锁定后的 HOP向未发生旁路切换的 RE下发配置数据，可以保证 各个 RE (除了被旁路的 RE )按锁定前的配置和状态工作， 从而提升射频 单元串联组网的可靠性， 无需额外增加网规人员的配置调整工作， 不需要 修改 HDLC和 CPRI协议标准；并且 REC根据未发生旁路切换的锁定后的 HOP和未发生旁路切换的实时 HOP可以识别出发生旁路的具体 RE,方便 维护。
