Description

信号的处理装置及方法
本申请要求在2017年09月14日提交中国专利局、申请号为201710829233.6的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，例如涉及一种信号的处理装置及方法。
背景技术
在相关技术中，随着传送网的不断升级，电信网络运营商将全面部署光传输网(Optical Transport Network，OTN)网络，包括骨干层网络、核心层网络、汇聚层网络以及接入层网络等。同步数字体系/多业务传送平台(Synchronous Digital Hierarchy/Multi-Service Transfer Platform，SDH/MSTP))承载的网络将陆续退出服务。在这个SDH/MSTP承载的网络全面升级到OTN承载的网络的过程中，有的客户需要继续使用原有的同步传输模块N级(Synchronous Transport Module level N，STM-N)业务，如何在将这部分业务平滑升级到由OTN网络承载，包括实现STM-N业务通道层交叉调度，是电信网络运营商面临的共同情况。
OTN网络承载STM-N业务通常是在OTN设备上重新开发客户侧接入单板22、线路侧接入单板以及交叉单板，来支持STM-N业务的接入以及通道层交叉调度，如附图1所示。图1是根据相关技术中OTN网络承载STM-N业务的示意图。如图1所示，在OTN网络上要承载STM-N业务，并支持通道层交叉调度，就需要增加至少3种单板，包括客户侧STM-N业务接入单板、通用虚拟容器/光通道数据单元a(Virtual Container/Optical channel Data Unit a，VC/ODUa)交叉单板，以及线路侧STM/OTN接入单板，这三种单板是OTN网络中成本最昂贵的单板。对于电信网络运营商管理的超大规模OTN网络来说，采用这种技术来承载STM-N业务，电信网络运营商将会付出一笔高昂的采购成本。而且在现网中更换通用VC/ODUa交叉单板，将会引起正在运行的OTN网络承载的业务中断，会带来巨大的工程改造升级工作量及风险。
针对相关技术中在OTN网络中承载STM-N业务成本高，可能导致业务中断的情况，目前还提出相应的方案。
发明内容

下面结合本申请示例实施例进行详细说明。
相关技术中OTN网络支持通道层交叉调度方式承载STM-N业务技术存在的成本昂贵、工程改造升级困难，本示例实施例提供了一种升级操作更加简单、成本更加低廉的OTN网络承载STM-N业务的方法及其装置。
本示例实施例采用以下技术方案：
需要补充的是，本申请文件中的ODUa和ODUk均是ODU信号，ODUk信号可以是数据量更大的OUD信号。
图3是根据示例实施例的OTN网络承载STM-N业务的方法流程图，如图3所示，该方法包括步骤S301至步骤S302。
为了更加容易理解，这里将VC交叉处理内部端口分为两部分，一部分端口用作与客户侧业务接入处理时建立ODUa交叉，这里称为客户侧VC端口，另一部分用作与线路侧业务接入处理时建立ODUa交叉，这里称为线路侧VC端口。
在步骤S301中，在OTN网络中客户侧业务接入时将接入的STM-N业务封装成ODUa信号，进入ODUa交叉矩阵进行交叉传送，对传送到VC交叉处理部分的客户侧VC端口的ODUa信号进行解封装，还原出STM-N信号。例如，可以按照以下步骤进行：先在OTN网络中客户侧处理接入的STM-N业务，并封装成ODUa信号；在客户侧业务接入后和进行VC交叉前进行建立ODUa交叉，将ODUa信号通过先建立ODUa交叉然后再传送到VC交叉处理；对VC交叉处理前对客户侧VC端口接收到的ODUa信号进行解封，还原为STM-N信号。
在步骤S302中，将VC交叉处理接收到的STM-N业务，映射成VC信号，进入VC交叉矩阵进行交叉传送，并对传送到VC交叉模块线路侧VC端口的VC信号进行解映射，还原为STM-N信号。例如，可以按照以下步骤进行：先将VC交叉处理接收到的STM-N业务映射到VC信号；在客户侧VC端口和线路侧VC端口之间建立VC交叉，将客户侧VC端口的VC信号通过VC交叉矩阵传送到线路侧VC端口，这里支持VC11、VC12、VC2、VC3、VC4等颗粒度的交叉，实现了STM-N业务通道层上下路选择、业务汇聚等核心调度功能；再对VC端口接收到的VC信号进行封装，生成为STM-N信号。
在步骤S303中，将VC端口上接收到的STM-N业务封装成ODUa信号，进入ODUa交叉矩阵进行交叉传送，并将传送到线路侧业务接入处理的ODUa 信号封装为OTN信号，在OTN网络中进行传送。
例如，可以按照以下步骤进行：先将VC端口接收到的STM-N业务封装成ODUa信号。在VC端口和线路侧业务接入模块之间建立ODUa交叉，将VC端口的ODUa信号通过ODUa交叉矩阵传送到线路侧业务接入处理部分。再将线路侧业务接入处理部分接收到的ODUa信号封装为OTN信号，在OTN网络中进行传送。
图4是根据示例实施例的OTN网络承载STM-N业务装置结构框图，如图4所示，包括：客户侧业务接入模块1，例如可以包括客户侧接入单板；线路侧业务接入模块2，例如可以包括线路侧接入单板；VC交叉调度模块3，例如可以包括ODU交叉单板；ODUa交叉模块4；业务调度管理模块；以及数据库模块6。
客户侧业务接入模块1，主要接入客户侧STM-N信号，并将STM-N信号映射成ODUa信号，设置为在客户侧业务接入单板与VC交叉模块客户侧VC端口之间建立ODUa交叉。
线路侧业务接入模块2，主要接入线路侧OTN信号，并将OTN信号映射到ODUa信号，设置为在线路侧业务接入单板与VC交叉模块线路侧VC端口之间建立ODUa交叉。
VC交叉模块3，主要将STM-N信号映射成ODUa信号，用作与客户侧业务接入模块、线路侧业务接入模块之间分别建立ODUa交叉；并将STM-N信号解映射成VC信号，用作VC交叉模块客户侧VC端口和线路侧VC端口之间建立VC交叉，实现STM-N业务通道层上下路选择、业务汇聚等核心交叉矩阵功能；VC交叉模块支持VC11、VC12、VC2、VC3、VC4等颗粒度的交叉。本模块的于ODUa交叉模块对接，输入和输出均为ODUa信号。
ODUa交叉模块4，主要负责ODUa信号交叉，包括客户侧业务接入模块与VC交叉模块客户侧VC端口之间的ODUa信号交叉，VC交叉模块线路侧VC端口与线路侧业务接入模块之间的ODUa信号交叉；这里支持ODU0、ODU1、ODU2、ODU3、ODU4以及ODUFlex等粒度的交叉，实现ODUa交叉矩阵功能。本模块从客户侧业务接入模块接收ODUa信号，把ODUa信号发送给线路侧传送模块。同时，本模块还与VC交叉模块对接，将ODUa信号发送给VC交叉模块进行VC交叉，并接收VC交叉模块还原回来的ODUa信号。
业务调度管理模块5，主要进行业务调度管理，多个模块之间通讯、配置和 调度等功能。
数据库模块6，主要存储相关配置信息，包括但不限于端口、业务类型、映射模式、交叉以及路径等相关配置信息的存储。
本示例实施例的技术方案中所述的客户侧业务接入模块、线路侧业务接入模块、ODUa交叉模块、业务调度管理模块和数据库模块都可以利用旧的设施(利用相关技术中的设施)，只需要增加独立的VC交叉模块，并进行软件升级即可在OTN网络中承载STM-N业务，并支持STM-N业务通道层上下路选择、业务汇聚等核心调度功能。采用本示例实施例所述在OTN网络中承载STM-N业务的方法及其装置，与相关技术相比，降低了在OTN网络中承载STM-N业务的硬件成本、工程改造风险以及工作量，提高了运营商OTN网络升级的效益。
结合附图对一种OTN网络中承载STM-N业务的装置与方法进行说明。
图5是根据示例实施例的一种OTN网络中承载STM-N业务的装置与方法业务调度流程图，如图5所示，该流程包括以下六个步骤。
步骤一，根据用户的STM-N业务类型，在客户侧业务接入模块接入端口上配置STM-N业务类型，并将STM-N信号映射到ODUk信号。
步骤二，根据网络路径规划数据，在线路侧业务接入模块接入端口上配置OTN业务类型，将OTN信号映射到ODUk信号，可能是ODU0、ODU1、ODU2或者ODUFlex。
步骤三，根据用户的STM-N业务类型以及网络路径规划数据，将VC交叉模块的内部端口划分为客户侧VC端口和线路侧VC端口，在VC交叉模块的客户侧VC端口和线路侧VC端口上分别配置具体的STM-N业务类型，并将STM-N信号直接映射到具体的ODUk信号。
步骤四，在客户侧业务接入模块接入端口和VC交叉模块客户侧VC端口之间建立ODUk交叉。
步骤五，在线路侧业务接入模块接入端口和VC交叉模块线路侧VC端口之间建立ODUk交叉。
步骤六，在VC交叉模块客户侧VC端口和VC交叉模块线路侧VC端口之间建立VC交叉，具体的VC交叉颗粒度根据客户侧VC端口业务映射确定，可能是VC11、VC12、VC2、VC3或者VC4。
到此，一条承载在OTN网络中的STM-N业务配置完成。
如附图5所示，本示例实施例的技术方案充分利用OTN网络中已经存在的 业务模块资源，避免了重新开发基于VC交叉调度的客户侧接入模块和线路侧接入模块。对于客户侧，充分利用OTN网络中已有的客户侧业务接入模块接入STM-1、STM-4、STM-16或者STM-64业务；对于线路侧，充分利用OTN网络中已有的线路侧业务接入模块传送承载STM-1、STM-4、STM-16或者STM-64的OTN业务。所有涉及STM-N业务终结、再生处理、上下路选择以及业务汇聚等交叉调度功能都在新开发的VC交叉模块中实现。
VC交叉模块可以作为一种新业务单板，可安装在OTN设备业务槽位中，可以安装多块VC交叉单板，使得VC交叉容量可以动态扩展。
图6是根据示例实施例的OTN网络中承载STM-N业务的装置硬件模块图，如图6所示，该装置包括客户侧接入模块，交叉模块以及线路侧接入模块。
客户侧接入模块由支持STM-1、STM-4、STM-16和STM-64业务的客户侧业务接入模块组成。
交叉模块由ODUa交叉子模块和VC交叉子模块组成，分别完成ODUa交叉矩阵和VC交叉矩阵功能。
线路侧接入模块由支持光通道传输单元(Optical channel Transport Unit，OTU)业务的线路侧业务接入模块组成。
除了VC交叉子模块需要新增，其他模块都可以利用旧OTN网络中已经存在的模块。
采用本示例实施例的技术方案，在具体的OTN网络中承载STM-N业务工程实施中，只需要新增加VC交叉单板，客户侧STM-N业务接入单板、ODUa交叉单板和线路侧OTN业务接入单板都可以利用旧OTN网络中已有的。和相关技术方案(附图1)相比，从采购成本上来说，本示例实施例只需要新增VC交叉单板，其他单板都可以利用已有的；从工程实施上来说，本示例实施例的技术方案具有操作简单、风险小、周期短等特点，可以降低工程改造升级的风险和工作量。
图7是根据示例实施例的OTN网络中承载STM-N业务的分层业务模型图，如图7所示，该分层业务模型包括VC路径，复用段路径，再生段路径，ODUk路径，ODU4路径，光通道路径，
VC路径：一条端到端STM-N业务的服务层路径，设置为承载客户层STM-N业务，被称为VC路径。
复用段(Multiplex Section，MS)路径：一条端到端VC业务的服务层路径， 设置为承载VC层业务，被称为复用段路径。

光通道(Optical Channel，OCH)路径：一条端到端ODU4业务的服务层路径，设置为承载ODU4层业务，被称为光通道层路径。
从客户侧业务依次往下，OCH路径下还有光复用段(Optical Multiplexing Section，OMS)、光传输段(Optical Transmission Section，OTS)等，这部分属于电信管理论坛(Telecom Management Forum，TMF)标准定义的OTN业务层次，这里不再赘述。
