Description

一种业务信息配置方法、装置及系统
本申请要求享有2018年08月03日提交的名称为“一种业务信息配置方法、装置、系统及存储介质”的中国专利申请CN201810879935.X的优先权，其全部内容通过引用并入本文中。
技术领域
本发明实施例涉及通讯技术领域，尤其涉及一种业务配置方法、装置及系统。
背景技术
随着中国移动全业务运营的开展，城域网所接入的业务也发生了巨大的变化。传统的城域网接入层以基站接入为主，但在全业务接入的背景下，还承担着集团用户、家庭小区的业务接入和各类专线任务。接入业务具有多样性，带宽也越来越大，如长期演进(Long Term Evolution，LTE)基站的高带宽、光线路终端(Optical Line Terminal，OLT)的1000M传输速率的以太网(Gigabit Ethernet，GE)，甚至10G的上行带宽，而大量大客户专线业务的接入带宽也要求达到GE，甚至更高。分组传送网(Package Transport Network，PTN)可以组建精品平面，实现3G、LTE阶段无线业务的回传，同时可以接入精品大客户专线业务。而大量的OLT上行业务以及普通大客户专线业务，可以通过光传送网络(Optica l Transport Network，OTN)实现高带宽的接入。
在LTE/LTE-A(LTE-Advanced，后续演进)的发展中，运营商为降低站点租赁费和基站资源集中管控，逐步采用基带处理单元(Building Base band Unit，BBU)集中做为主流建网方式。基带部分(BBU)集中放置于综合机房，射频部分(RRU，Radio Remote Unit)全室外布置于各覆盖点，BBU与RRU通过通用公共无线电接口(Common Public Radio Interface，CPRI)进行业务拉远。室外OTN设备(RRU侧)和综合机房OTN设备(BBU侧)进行对接传输。开局进行业务开通时，首先通过网线连接室外OTN设备，使得设备和网管处于同一网段，然后利用网管服务器建立网元对OTN设备进行管理，在网管可以监控这个设备之后。通过网管界面对其进行业务配置，设置对应的交叉来进行业务开通。从这个过程看出此方式由于RRU侧OTN设备的地点灵活放置，有可能是很偏僻的地方，RRU侧很多情况下通过网管管上有很大困难(网线，网管服务器固定，必须 携带便携服务端跟随设备先去开通，然后在业务开通后和主网元串联)，增加了开局的难度，而且必须专业人员去现场进行业务开通，增加了运营成本。
发明内容
有鉴于此，本发明实施例的目的在于提供一种业务配置方法、装置及系统，以解决现有技术中RRU侧OTN设备进行管理中开局的难度，而且必须专业人员去现场进行业务开通，运营成本大的问题。
本发明实施例解决上述技术问题所采用的技术方案如下：

接收所述BBU侧的OTN设备发送的低阶开销字节；
从所述低阶开销字节中提取并配置客户侧业务数据。
根据本发明实施例的第二个方面，提供一种OTN设备，所述OTN设备设于RRU侧，其包括存储器、处理器及存储在所述存储器上并可在所述处理器上运行的计算机程序，所述计算机程序被所述处理器执行时实现如第一方面所述的方法的步骤。

所述BBU侧网元，用于设置线路侧业务数据和客户侧业务数据，其中所述线路侧业务数据设置在高阶开销字节中，所述客户侧业务数据设置在低阶开销字节中；
所述BBU侧OTN设备，用于在所述BBU侧网元完成线路侧业务数据和客户侧业务数据设置后向所述RRU侧ONT设备发送所述高阶开销字节，并在线路侧业务建立后向所述RRU侧ONT设备发送所述低阶开销字节；
所述RRU侧ONT设备，用于根据接收的高阶开销配置线路侧业务数据，根据接收的低阶开销字节配置客户侧业务数据。
本发明实施例的业务配置方法、装置及系统，ONT设备利用高阶开销字节传送线路侧业务数据，利用低阶开销字节传输客户侧业务数据，使RRU侧的OTN设备无需在现场进行网管管理及配置，就能够自动跟随上游BBU侧OTN设备业务配置，具备自动开通业务功能，克服了现有技术中RRU侧OTN设备进行管理中开局的难度，而且必须专业人员去现场进行业务开通，运营成本大的问题。

BBU侧的网元NE2设置业务与交叉，业务接入NE2，并承载交叉到线路，在RRU侧网元NE1(实际应用中，网元NE2可以是虚拟的)，NE1业务与交叉面配置开通。
本实施例中，BBU侧设备业务及交叉可以通过人工设置，RRU侧设备业务及交叉则根据BBU侧业务配置，实现自动开通。
在一个可行的方案中，该高阶开销字节包括设置在高阶净荷结构指示标识PSI中的复帧结构指示MSI高阶开销字节，该MSI高阶开销中插入了该BBU侧的光信道OCH侧时隙的光通路数据单元ODUK类型；
该低阶开销字节包括设置在低阶PSI中的MSI低阶开销字节，该MSI低阶开销中插入了RRU侧客户端口对应的业务类型及客户端口号。
在一个可行的方案中，步骤S102、从该高阶开销字节中提取并配置线路侧业务数据，包括：
从所述高阶PSI中提取MSI高阶开销字节；
根据该MSI高阶开销字节携带的信息，为线路侧配置光通道数据单元ODU的时隙。
在一个可行的方案中，步骤S103、从该低阶开销字节中提取并配置客户侧业务数据，包括：
从所述低阶PSI中提取MSI低阶开销字节；
根据该MSI低阶开销字节携带的信息，获取客户端口业务配置信息及交叉信息；
根据该客户端口业务配置信息及交叉信息建立指定客户端口的业务。
实际应用中，可以利用光通路净荷单元(optical channel payload unit，OPUK)复用开销中的复用结构指示MSI开销字节。具体如图3所示，高阶开销字节传递线路侧业务数据，低阶开销字节传递客户侧业务数据，这样做的一个最明显的有点就是层次分明，容易理解。
对于BBU侧NE2网元的设备，由于NE2是通过网管管理，界面支持对应业务以及交叉配置，NE2网元设备按照标准要求在线路侧高阶开销(如高阶净荷结构指示标识PSI)中设置MSI高阶开销字节，同时在MSI高阶开销字节中插入本端光信道(optical channel，OCH)侧各时隙的光通路数据单元类型(optical channel date Unit，ODUK)，在低阶开销中设置MSI低阶开销字节，并在其中插入RRU侧客户端口对应的业务类型及 客户端口号(具体交叉到哪个客户端口，在BBU侧网管进行指定)。当BBU侧配置完成后，BBU侧的OTN设备就可以与RRU侧的OTN设备建立线路侧业务。
对于RRU侧NE1网元的设备，首先通过MSI高阶开销字节获取BBU侧关于线路侧的配置。RRU侧根据信息配置线路侧业务，在线路侧业务配置完成后，RRU侧就可以获取MSI低阶开销字节(实际应用中，当线路侧时隙都配置准确之后，RRU线路侧就能获取到对应的低阶开销)，利用低阶开销传过来的信息配置对应的客户端口业务，交叉配置根据获取到低阶开销的首时隙，交叉此时隙指定的客户端口；此时，RRU侧线路侧、客户侧业务配置及交叉建立完成，业务开通完毕。
在一个可行的方案中，步骤S104、从该低阶开销字节中提取并配置客户侧业务数据之后，该方法还包括：
据接收的业务信息，更新该RRU侧设备的业务与交叉配置。
实际应用中，RRU侧设备的业务与交叉配置的更新包括业务的删除与增加。
当某个客户端口的业务开通后，RRU侧的OTN设备的业务端口在每次接收到BBU侧的信息后，就开始等待下一条信息，如果经过预设时长后未收到任何信息，则可认为该客户端口的业务在BBU侧已被删除，此时可删除RRU侧对应的业务。
若增加业务配置，先执行业务配置后执行交叉配置。
本发明实施例业务配置方法，OTN设备利用高阶开销字节传送线路侧业务数据，利用低阶开销字节传输客户侧业务数据，使RRU侧的OTN设备无需在现场进行网管管理及配置，就能够自动跟随上游BBU侧OTN设备业务配置，具备自动开通业务功能，不需要下到站点，只需接通光纤即可开通业务，降低了开局难度和运营成本。
为了更加详细的对本发明进行说明，在前述实施例的基础上，本发明实施例二提供了另一种业务配置方法，该方法结合光信道传送单元OTU2(净荷类型21)承载通用公共无线电CPRI3业务来进行说明。请参阅图4，带双向箭头的业务线为其中一条业务，在网络组网完成后，整体流程由BBU侧设备发起，RRU侧设备跟随BBU侧的配置，若BBU侧业务变更，则RRU侧设备跟随变更。
请参阅图5，基于BBU侧设备和RRU侧设备功能流程，对本实施例进行描述：
S501、BBU侧设备网管配置业务。
实际应用中，BBU侧配置的业务包括线路侧业务和客户侧业务。
对于线路侧业务(包括两个ODU1，分别占用第1、2,3、4时隙)，为了保证RRU侧获取到正确的ODUk类型，使用净荷结构标识PSI[14-29]描述八个时隙的ODUK类型。本实施例中，可以在高阶PSI开销中设置MSI高阶开销字节，同时MSI高阶开销字节中插入本端OCH侧各时隙的ODUK类型。
对于客户侧业务(CPRI3)，采用标准映射方式到ODU1。本实施例中，可以在低阶PSI开销中设置MSI低阶开销字节，在MSI低阶开销字节中插入RRU侧客户端口对应的业务类型及客户端口号。
BBU线路侧业务配置成功后，线路侧业务就已经开通通了(本实施例中RRU线路侧默认为OTU2业务)。
S502、BBU侧OTN设备根据线路侧业务配置向RRU侧ONT设备发送高阶PSI开销字节。
S503、RRU侧OTN设备提取高阶PSI开销字节，根据高阶PSI开销字节配置ODU1时隙。
根据MSI开销字节携带的信息，参见图6，1、2时隙的支路端口一致，根据PSI[14-15]、PSI[16-17]说明这两个时隙是ODU1，这样线路侧就可以配置ODU1(占用1,2时隙)，同样的方法可以实现另一个ODU1(占用3，4时隙)的配置。
实际应用中，RRU侧线路业务配置需要的信息如表1所示。
表1线路侧低阶ODUk信息
业务配置信息 来源 备注
映射方式 PT G.709 15.9.2.1.1
端口号 MSI G.709 19.4.1，基于MSI首时隙占用位置
占用时隙 MSI G.709 19.4.1，基于同编号时隙列表
ODUk类型 PSI[14～29] 私有定义
S504、BBU侧设备网管在低阶PSI开销中设定RRU侧客户端口交叉与线路侧(OCH)的时隙对应关系。
为了设定RRU侧客户端口交叉到OCH侧的哪个时隙，需要在BBU网管指定。本实施例中，1、2时隙指定客户端口一，3、4时隙指定客户端口五，此步骤完成RRU侧客户侧(OAC)端口号和时隙对应关系，为RRU侧建立交叉做准备。
S505、BBU侧OTN设备将低阶PSI开销传递到RRU侧OTN设备。
S506、RRU侧OTN设备从低阶PSI开销中获取到客户端口业务配置信息及交叉信息，并执行OAC业务映射配置。
本步骤中，RRU侧客户业务配置需要的信息如表2所示。
表2客户侧端口信息
业务配置信息 来源 备注
映射方式 PSI[10] 私有定义
端口号 PSI[11-12] 私有定义(步骤3指定)
占用时隙 无 客户端口占满整个时隙
ODUk类型 PSI[13-14] 私有定义
根据以上四个信息即可建立指定客户端口的业务。
当RRU执行完OAC业务映射配置后，将客户端口一交叉到线路口3、4时隙，将客户端口五交叉到线路口1、2时隙，如此交叉配置完成后，即完成RRU侧客户侧端口一、五的业务自动开通。
实际应用中，针对图3中的基于线路侧高/低阶ODUk的PSI开销，需要实时更新RRU侧设备的业务与交叉配置。同时保证，若增加业务配置，先执行业务配置后执行交叉配置；若删除业务，先执行交叉删除后，再删除业务。
本发明实施例业务配置方法，OTN设备利用高阶开销字节传送线路侧业务数据，利用低阶开销字节传输客户侧业务数据，使RRU侧的OTN设备无需在现场进行网管管理及配置，就能够自动跟随上游BBU侧OTN设备业务配置，具备自动开通业务功能，不需要下到站点，只需接通光纤即可开通业务，降低了开局难度和运营成本。
