Description

一种开销信息的传输方法及装置
技术领域
本发明涉及到微波传输技术领域, 特别涉及到在微波传输中微波帧 开销(RFCOH )的传输方法、 开销信息传输装置以及开销信息的接收装 置。 发明背景
在微波传输技术领域, 现有的规范建议已经对各种速率等级业务传 输时所占用的信道带宽给出了严格要求。 例如, 对于采用四相相移键控 ( QPSK ) 方式在 13GHz的中心频率传送的 4路 E1业务, 欧洲电信标 准协会建议其信道带宽要小于 2.7MHz。 然而, 为了灵活地进行网络管 理, 需要在有限的信道带宽内传输丰富的用于管理的微波帧开销信息。
目前, 业界采用较多的微波帧开销传输方法包括以下步骤: 首先将 待传送的异步数字序列 ( PDH )或同步数字序列 (SDH )业务打包后形 成 PDH或 SDH净荷( Payload ),然后在所述 PDH Payload或 SDH Payload 前面添加对应各个 PDH Payload或 SDH Payload的微波帧开销字节, 形 成在微波链路中传输的微波帧。 通过上述方法生成的微波帧的结构如图 1所示, 其中, 微波帧开销字节主要包括:—帧头(FA )、 自适应发信功率 控制 (ATPC )、 网管 DCC字节 (DATA )、 公务字节 (RSC )、 微波链路 路径标识(Link ID )、 微波帧的通道性能状态检测字节 (MVV5 ) 以及 微波帧的信号踪迹字节 (MVJ0 )等等。 其中, MVV5包括: BIP2校验 格式的 MVB1位、 指示远端微波站误码指示的 MVREI位以及指示远端 微波站的告警 (缺陷指示) 的 MVR I位。 在通常情况下, 对应每个微 波帧, 上述 ATPC、 Link ID、 MVV5以及 MVJO等开销字节将占用至少 4个字节 (byte ), 其中, 仅 Lirik ID—项开销就占用 2个字节。 发明内容
本发明提供了一种开销信息的传输方法及开销传输和接收装置, 可 以在有效的传输带宽内传输丰富的开销字节, 同时还可以降低对接收端 的接收灵敏度要求, 从而解决传输带宽、 开销字节的传输以及接收机灵 敏度之间的矛盾。
本发明实施方式的开销信息传输方法, 包括:
将待传输的开销信息划分并重组成至少两个的开销部分;
将所划分的至少两个开销部分依次添加到与所述开销部分——对应 的至少两个数据帧的开销字节中, 并通过所述两个以上数据帧发送。
本发明实施方式的开销信息传输装置包括:
开销部分生成单元, 用于将待传输的开销信息划分并重组成至少两 个开销部分;
数据帧生成单元, 用于将来自开销部分生成模块的至少两个开销部 分依次添加到与所述开销部分——对应的至少两个数据帧的开销字节 中, 并通过所述至少两个数据帧发送。
本发明实施方式的开销信息接收装置包括:
数据帧接收单元, 用于从接收到的至少两个数据帧中依此提取至少 两个开销部分; 以及
开销信息恢复单元, 用于将数据帧接收单元提取的至少两个开销部 分恢复成开销信息。
由此可以看出, 如果采用现有开销传输方法, 对每个微波帧开销的 传输将占用较大的传输带宽,例如,对于采用 QPSK方式调制的 4路 E1 业务而言, 仅 Link ID—项开销就将占用 1.5%的信道带宽。 这样, 在满 足欧洲电信标准协会所制定的规范建议中对信道带宽要求的前提下, 由 于微波帧的开销字节占用了较大的信道带宽, 这必然使每个微波帧的
Payload 中用于对所传输信息进行纠错的纠错字节减少, 造成纠错编码 效率的降低, 从而导致编码增益降低, 这会将对接收端的接收灵敏度提 出很高的要求, 最终导致系统成本的增加。 而本发明实施例充分地利用 了微波帧开销中的某些开销字节不需要高速传输的特点, 将这些开销字 节划分成若干部分, 并通过多个微波帧传输, 从而大大地降低了每个微 波帧中开销字节所占用的信道带宽。 通过本发明实施例的方法, 节省得 到的信道带宽可被用于对所传输信息进行纠错编码, 从而可以提高编码 增益, 降低接收机的灵敏度要求, 最终实现微波传输系统成本的降低。 附图简要说明

图 2为本发明实施例所述的开销信息传输方法流程图;
图 3为本发明实施例所述微波帧的结构示意图;
图 4为本发明实施例所述的 MVOH组成结构示意图;
图 5为本发明实施例所述的开销信息传输装置结构示意图; 图 6为本发明实施例所述的开销信息接收装置结构示意图。 实施本发明的方式 - 为使发明的技术方案及优点更加清楚明白, 以下参照附图并举实施 例, 对本发明作进一步详细说明。
在微波帧开销字节中, Link ID在微波传输中的作用是主要用于标识 微波传输链路, Link ID为对应两个收发站点之间的链路标识编号。目前, 可以通过软件设置某个微波链路应当发送和应当接收的 Link ID。如果某 个链路的应当接收的 Link ID和实际接收的 Link ID不一致,将产生 Link ID 不匹配告警,表征该链路的 Link ID出现误码或是收到非法链路的微 波信号。 考虑到全网的复杂情况, 共定义从 1到 4094共 4094路微波链 路的 Link ID, 因此共需要用 16个比特(bit )来标识上述 4094路微波 链路。 如果在一个微波帧中传输这 16个比特, 则共需要两个字节。 如 前所述,这将会占用较大的信道带宽,造成所承载信息编码增益的下降。 鉴于网络的 Link ID不存在较高的传输速率要求, 因此, 在本发明的一 个实施例中 , 将 Link ID划分为若干部分, 分别在若干个微波帧中传输, 从而可以降低每个微波帧中所携带的开销字节数, 减少开销字节所占用 的信道带宽。 例如, 本发明另一实施例中, 将 Link ID字节分成两部分, 分别在两个连续的微波帧中传输, 则每个微波帧所携带的开销字节就将 减少一个字节。
同理, 上述思想还可以应用到微波帧开销中其他不需要高速传输的 开销字节, 具体方法包括: 将这些开销字节划分成若干部分, 并将不同 开销的对应部分复用在一起, 通过多个微波帧传输所划分的各个部分, 帧中传输开销字节所占用信道带宽的目的。
下面将通过本发明的一个实施例详细说明本发明的方法。 在本实施 例中,不需要高速传输、可以划分为多个部分分别传输的开销字节包括: 4个比特的 ATPC、 16个比特的 Link ID、 1个比特的 MVREI、 1个比特 的 MVRDI和 1个比特的 MVB1等 MVV5开销信息以及 8个比特的 MVJOo
如图 2所示, 本实施例所述的方法主要包括以下步骤:
A、 将每个 ATPC分成 4份, 每份 1个比特, 分别在连续的 4个微 波帧中传输, 因此, 每帧只需要携带 1比特的 ATPC信息; 将每个 Link ID分成 16份,每份 1个比特,分别在连续的 16个微波帧中传输, 因此, 每帧只需要携带 1比特的 Link ID信息;将每个 MVJ0分成 8份,每份 1 个比特, 分别在连续的 8个微波帧中传输, 因此, 每帧只需要携带 1比 特的 Link ID信息。
B、依次将 4个 ATPC划分后得到 16个比特中的 1比特、 1个 Link ID 划分后得到的 16个比特中的 1比特、 2个 MVJ0划分后的到的 16个比 特中的 1 比特以及 MVV5 开销信息中的一个开销比特例如 MVREI、 MVR I或 MVB1 , 复用在一起, 生成 16个长度为 4比特的开销信息。
C、使用长度为 4比特的微波帧的复帧指示(MVH4 )标识当前生成 的 16个长度为 4比特的开销信息, 并与所标识的 4比特开销信息组合 在一起得到 16个长度为 1个字节的开销部分, 又称为微波帧开销部分
( MVOH )并将所生成的 16个开销部分依次添加到连续 16个 波帧的 RFCOH中, 形成在微波链路中传输的 16个微波帧。
该微波链路的接收端在接收到上述微波帧后, 可以采用现有的接收 方法接收所述微波帧。 所述接收端在连续接收到若干个微波帧后, 就可 以才 据各个开销部分的划分方法解析得到相应的开销字节。 例如, 接收 端在连续接收 4个微波帧后, 就可以将从这 4个微波帧中接收的 ATPC 比特组合在一起得到一个完整的 ATPC开销;接收端在连续接收 16个微 波帧后,就可以将从这 16个微波帧中接收的 Link ID比特組金.在一起得 到一个完整的 Link ID;接收端在连续接收 8个 波帧后,就可以将从这 8 个 波帧中接收的 MVJ0 比特组合在一起得到一个完整的 MVJ0 开 销。 由于在上述实施例中, 划分为多个开销部分的开销均是对传输速度 要求不高的开销字节, 因此, 这种慢速率地传输上述开销字节的方法是 可以被接受的。
通过上述实施例所述的方法所形成的微波帧结构如图 3所示, 与图 1所示的帧结构相比,开销字节的数目从至少 7个字节减少为 4个字节, 减少了至少 3个字节, 从而可以大大节省传输开销字节所占用的信道带 宽。
本发明的实施例还给出了上述步骤 B所述的将 1比特 ATPC、 1比 特 Link ID、 1比特 MVJ0以及 MVV5开销信息中的某个开销比特复用 在一起方法。 通过这种方法复用后得到的 1字节开销部分 MVOH所包 含的各个开销比特如图 4所示, 其中, 该开销字节的第 0〜3比特所承载 的是 4比特的 MVH4,用于标识本开销字节所传输的是哪个 ATPC比特, 哪个 Link ID比特, 哪个 MVJ0比特以及哪个 MVV5开销比特; 该开销 字节的第 4比特所承载的是 1比特的 ATPC; 第 5比特所承载的是 1比 特的 Link ID; 第 6比特所承载的是 1比特的 MVV5开销; 而第 7比特 所承载的是 1比特的 MVJ0。与各 MVH4值对应的开销信息如表 1所示。 表 1 实际上也显示了在连续 16个微波帧的开销字节中所传输的开销部
Figure imgf000008_0001
表 1
由于 MVH4包括 4个比特, 共可以标识 16种开销信息的組合, 也 就是可以分别标识在 16个微波帧中传输的不同的开销部分。 从表 1可 以看出, 由于 ATPC仅包含 4个比特, 因此, 每 4个连续的无线帧将发 送一个完整的 ATPC; 由于 Link ID包含 16个比特,每 16个连续的无线 帧将发送一个完整的 Link ID; 由于 MVJ0包含 8个比特,每 8个连续的 无线帧将发送一个完整的 MVJ0;而 MVV5将以 MVB1、MVB1、MVREI、 MVR I的顺序循环发送。
从上述本发明的实施例可以看出, 该方法通过将对传输速率要求不 高的开销字节划分成若干部分, 并经过复用后, 通过多个微波帧传输到 接收端, 可以大大降低每个微波帧中开销字节所占用的信道带宽。 若将 节省得到的信道带宽用于对所传输信息进行纠错编码, 就可以解决传输 带宽、 开销字节的传输以及接收机灵敏度之间的矛盾, 从而提高编码增 益, 降低接收机的灵敏度要求, 实现微波传输系统成本的降低。
本发明的另一个实施例给出了一种开销信息传输装置, 其内部结构 如图 5所示, 主要包括: 开销部分生成单元和数据帧生成单元。
其中, 所述开销部分生成单元用于将待传输的开销信息划分并重组 成至少两个部分, 生成至少两个开销部分, 并将生成的开销部分发送给 所述数据帧生成单元;
所述数据帧生成单元用于将来自开销部分生成模块的至少两个开销 部分依次添加到与所述开销部分——对应的至少两个数据帧的开销字 节中, 并通过所述至少两个数据帧发送。
其中, 所述开销部分生成单元包括: 开销信息划分模块和开销信息 重组模块。
其中, 所述开销信息划分模块用于将待传输的备类开销信息分别划 分为至少两个的信息部分, 并将划分后的各类开销信息的信息部分分别 发送到所述开销信息重组模块;
所述开销信息重组模块用于将接收的各类开销信息的信息部分重新 组合成至少两个开销部分。
