Description

一种光网络单元业务信息的发放方法、装置及光线路终端 技术领域
本发明涉及通信技术领域，特别是指一种光网络单元业务信息的发放方法、装置及光线路终端。
背景技术
无源光网络系统(Passive Optical Network，简称为PON)技术目前已经是光接入网领域的首选技术，其在接入速率、带宽效率、分光比、全业务承载能力以及安全性方面都具有明显优势。PON技术还分为以太网无源光网络(Ethernet Passive Optical Network，简称为EPON)和无源光接入系统(Gigabit-Capable PON，简称为GPON)，EPON技术由IEEE802.3EFM工作组进行标准化；GPON技术是由国际电信联盟远程通信标准化组提出并标准化，最终形成了G.984.x系列标准。
无论是EPON还是GPON技术，宽带接入业务种类都是一样的，业务配置步骤也大体相同，PON目前可提供的业务种类包括宽带上网业务、语音网络电话(Voice over Internet Protocol，简称为VoIP)、视频业务等，业务配置过程主要是依据各自标准。从PON层面上说一条端到端业务的配置起始点是ONU物理终端点用户端口，终端点是光线路终端(optical line terminal，简称为OLT)上联虚端口，配置业务的过程就是在两点间配置一系列业务数据，业务数据主要包括业务划分(例如VLAN、优先级、以太网类型)、业务服务质量(Quality of Service，简称为QoS)(例如流量限速、优先级队列映射)、具体业务详细配置参数(例如VoIP语音相关详细参数)等方面的内容。
运营商发放FTTH ONU业务前，需要首先完成基础设施搭建工作，主要包括局端设备就绪以及光纤/分光器铺设。目前的新建住宅小区，一般在小区竣工时，就完成了光纤/分光器的铺设，光纤接头通到了每家每户；与此同时，运营商的资源系统RMS也录入了光纤从局端主干光纤到分光器再到用户端光纤的路由信息，如果辅以智能光分配网络等技术，RMS系统能得到更准确的且基本不依赖于人为录入的数据。
基础设施搭建工作完成后，运营商即可在营业厅受理用户的业务发放申请，目前典型的业务发放流程参见附图1，分为如下几步：
S11：营业厅受理用户的业务发放请求。
S12：运营商的业务激活系统后台完成OLT的上层设备的业务配置，主要包括：宽带远程接入服务器(Broadband Remote Access Server，简称为BRAS)上的宽带上网业务配置、交互式网络电视IPTV平台上的IPTV业务配置、软交换平台上的语音业务配置等。
S13：查询RMS系统，获取用户家庭住址处光纤所上连的OLT设备信息，主要包括：上 连的OLT设备的IP地址、板卡槽位号、PON端口号。
S14：定位、获取OLT设备信息后，在OLT设备上完成用户ONU的业务配置，主要是二层协议以及PON相关的配置，为OLT上层业务提供基础承载。需要特别说明的一点是，按照目前典型的PON业务配置流程，需要在此步配置中指定用户的ONU唯一标识SN。(ONU唯一标识，对于EPON，按标准可以使用MAC或SN；对于GPON，按标准可以使用PASSWORD或SN。此外，一些运营商可能对标准做一些扩展，定义其它的唯一标识，例如，中国电信使用LOID作为ONU唯一标识，统一称这些唯一标识为SN)。
S15：运营商施工人员从库房领用ONU，到用户家中安装。安装ONU前，施工人员需要先设置ONU的SN，使其与之前在OLT设备上指定的SN号一致。ONU安装完毕上电后，ONU会向OLT注册，此时OLT查询到其之前已配置的ONU信息的SN号和当前上线注册的ONU的SN号一致，认证通过，OLT上完成配置关联，并向ONU下发配置数据。至此，业务发放基本完成。
由上可知，上述业务发放过程需要先查询RMS数据，定位OLT网元、PON单板以及PON端口，预先通过EMS配置好ONU配置数据条目，ONU的SN号需要先录入，施工人员到用户家中开通ONU时，ONU的SN号也必需设定一致。ONU首次上线时，OLT核对SN一致后，才会认证通过ONU并下发配置数据，该过程比较繁琐，延长了业务开通时间，降低了业务开通效率。
发明内容
本发明的目的在于提供一种光网络单元业务信息的发放方法、装置及光线路终端，解决相关技术中的ONU业务信息发放过程繁琐，业务开通效率低的问题。

具体实施方式
为使本发明要解决的技术问题、技术方案和优点更加清楚，下面将结合具体实施例及附图进行详细描述。
本发明实施例提供了光网络单元业务信息的发放方法、装置及光线路终端，解决了相关技术中的ONU业务信息发放过程繁琐，业务开通效率低的问题。
本发明实施例的光网络单元业务信息的发放方法，如图2所示，包括：
步骤S21：获取待注册光网络单元ONU的注册请求，并根据所述注册请求获取所述待注册ONU的序列号SN以及与所述待测ONU连接的光线路终端OLT的端口信息。
其中，所述端口信息包括：与所述待注册ONU连接的PON端口以及所述PON端口所在的PON单板槽位。
步骤S22：在一业务数据表中查找资源占用标识符为预设值的数据资源，选择所述资源占用标识符为所述预设值的其中一数据资源作为下发资源，发送至所述待注册ONU，其中所述资源占用标识符设置为所述预设值时，表明相对应数据资源未被占用。
本发明实施例的光网络单元业务信息的发放装置，运营商营帐客服人员为用户完成业务受理后，用户领取ONU直接接上光纤、网线和电话线，即可完成FTTH ONU的开通，本发明无需用户进行任何专业配置，即可享用FTTH提供的各种业务，大大简化了业务信息的发放过程。
进一步地，所述选择所述资源占用标识符为所述预设值的其中一数据资源作为下发资源，发送至所述待注册ONU的步骤包括：
选择所述资源占用标识符为所述预设值的其中一数据资源；
将所选择数据资源对应的资源占用标识符替换为所述待注册ONU的SN，并将替换后的数据资源作为所述下发资源；
将所述下发资源发送给所述待注册ONU。
进一步地，在所述获取待注册ONU的注册请求的步骤之前还包括：
在所述OLT的每个PON单板的每个PON端口下配置一业务数据表，所述业务数据表包括N个数据资源，N为所述PON端口的最大分光比。
在本发明的具体实施例中，针对每块PON单板的每个PON端口，根据端口的最大分光比，预先配置好ONU，例如当最大分光比为64时，每个PON口下，都预先加入64条数据资源。其中，每条数据资源包括：PON单板槽位编号、PON端口编号、ONU编号、ONU SN以及ONU的其他业务配置数据，其中，ONU SN作为资源占用标识符，默认先全部配置为预设值，如0；ONU编号从1到64递增；ONU的其他业务数据，按照业务规划预先配置好，且上述配置数据，既可以在OLT发货时，由设备开发商提前配置好，也可以在OLT部署完毕后，采用设备开发商的提供的批量数据配置工具，一次性批量配置完成。
下面具体说明本发明实施例的实现过程。
假设用户ONU的SN为“10001055”，该用户ONU通过光纤和分光器，最终上连到OLT设备的11槽位PON单板的1号PON端口，从图3可以看出，该PON端口的最大分光比为64，且ONU业务信息发放完成前已经配置并连接了61个，如图4所示，本发明实施例包括：
步骤S41：用户ONU连接到11槽位PON单板的1号PON口；
步骤S42：所述ONU向其连接的OLT发送注册请求；
步骤S43：OLT收到注册请求后，获取ONU的SN号以及所述ONU连接的PON单板和 PON端口；
步骤S44：OLT在所述PON单板的PON端口对应的业务信息表中查找ONU SN为0的数据资源；
步骤S45：判断在所述业务信息表中是否能查找到一条ONU SN为0的数据资源；
步骤S46：若能查找到，则将所述数据资源中的ONU SN替换为用户ONU的SN，并将替换后的数据资源远程下发给用户ONU；
步骤S47：用户ONU注册成功；
步骤S48：若不能查找到，用户ONU注册失败。
本发明实施例不需要查询RMS系统获取OLT设备信息以及光路信息，ONU上线时，会自动通过光线路，将SN号上报给其物理连接到的设备，该设备自动挑选ONU SN为0值的条目，替换SN号为上报的SN值，并认证通过ONU后下发数据资源，且本发明不需要施工人员现场施工，节约了人力成本。
在本发明的具体实施例中，由于ONU的序列号已经不再作为PON业务及二层业务配置层面的唯一且需要预先指定的标识，用户领一个ONU，无论SN为何值，只需要接上光纤，PON业务以及二层业务即可打通。因此，当用户侧拆机、用户更换ONU，局端PON板或PON口故障需要将主干光纤拨出换到另一个PON口时，都不需要在EMS上更改配置。另外，由于只要对应的PON端口上有SN为0的数据资源，即可被待注册ONU利用，会不可避免地会留下脏数据。例如：如果之前一条数据资源已经被使用，即填写了SN号，但后来此SN号对应的ONU被拆机或者被更换，该数据资源则作废，但由于SN号不为0，不能重新指配给其它新上线的ONU，于是就作为一条脏数据留在了OLT的业务数据表中。
基于上述问题，本发明实施例的发放方法还包括：
按照预设周期，在每个PON单板的每个PON端口对应的业务数据表中，查找是否存在资源占用标识符不为所述预设值的第一数据资源；
若所述业务数据表中存在所述第一数据资源，则获取与所述第一数据资源的资源占用标识符对应的ONU的登陆状态；
若与所述第一数据资源的资源占用标识符对应的ONU的登陆状态为离线，且离线天数大于预设阀值，则将所述第一数据资源的资源占用标识符更改为所述预设值。
具体的，如图5所示，包括：
步骤S51：当天的定时任务计划时间到，启动定时任务；
步骤S52：在每个PON单板的每个PON端口对应的业务信息表中，查找ONU SN不为0的数据资源；
步骤S53：判断是否能够查找到下一个ONU SN不为0的数据资源；
步骤S54：若不能查找到，则当日定时任务完成；
步骤S55：若能查找到，则判断该ONU SN对应的ONU是否离线；
步骤S56：若不是离线，则清除ONU SN对应的ONU的连续离线天数记录；
步骤S57：若离线，则记录或更新所述ONU的连续离线天数，首次(记录)：Day＝1；非首次(更新)：Day＝Day+1；
步骤S58：判断所述连续离线天数是否大于预设阀值N；
步骤S59：若大于所述预设阀值，则将所述数据资源中的ONU SN替换为0，完成数据资源回收，并转入步骤S56，然后转入步骤S53；若小于所述预设阀值，则转步骤S53。
本发明实施例通过启动一个后台任务定期清理脏数据，来回收数据资源，此后台任务可以在OLT设备上实现，也可以在EMS上实现。此外，对于此后台任务，当分配给某ONU的数据资源被误回收时，ONU再次上线时，仍可同ONU第一次上线时一样，OLT侧会重新寻找一个ONU SN号为0值的条目，指配给ONU。
下面结合具体运维需求以及运维场景，对本发明实施例做一些补充说明。
(1)关于用户申请不同业务带宽时的处理
当用户申请不同业务带宽时，可参考数字用户线路接入复用器(Digital Subscriber Line Access Multiplexer，简称为DSLAM)业务，用户带宽限制，主要是在宽带远程接入服务器BRAS上限制，在PON层面，按默认的最大带宽统一配置即可。
(2)关于用户的认证及用户账号安全问题
对于合法用户，在营业厅开户时，可以记录用户的ONU SN信息到营帐系统。此后，可以通过定义点到点协议PPPoE账号+上报定位信息的格式，在用户PPPoE拨号时，上报用户设备物理位置(PON设备IP+PON单板+PON端口+ONU号)，同时上报用户的ONU的SN。用户首次PPPoE拨号认证成功后，可以在宽带远程接入服务器(Broadband Remote Access Server，简称为BRAS)上完成用户设备物理位置、用户设备SN号以及用户PPPoE账号三者的绑定，具体的绑定策略，根据用户账号安全策略以及运维灵活度折衷考虑。优选地，仅仅绑定SN号和PPPoE账号，因为当OLT局端因设备故障进行更换PON口等操作时，都不会对用户业务造成影响，当然，对于此种绑定策略，如果用户ONU故障需要更换ONU，在用户到营业厅申领新的ONU时，SN号和PPPoE账号的绑定关系，需要通过后台系统重置。当非法用户随便接一个ONU到用户家中的光纤上时，因为用户没有PPPoE账号，即使OLT设备认证了ONU，用户最终还是无法实现上网等业务。
(2)关于用户申报故障时的ONU定位
具体的，可通过两种方案来实现：一种是可以根据ONU的SN进行定位，在给用户开通 业务时，可记录ONU SN信息到营帐系统，用户申报故障后，可根据用户的资源信息查到ONU的SN，再到EMS中根据SN定位到ONU的位置。因此，本发明实施例中进行脏数据回收时，周期需要设定一个合理值，不宜太小，否则ONU的SN很快被回收不方便故障定位；另外一种定位方案是通过BRAS记录、收集PPPoE+上报的物理位置信息，后续用户申报故障时，可以直接查询之前收集到的物理位置信息，快速定位ONU。
(3)关于局端OLT设备故障问题
在局端OLT设备故障时，进行PON口割接。此时，无需进行任何数据配置，直接将主干光纤接到另外一个PON口即可，此光纤下挂的ONU，会全部自动在新接的PON口下重新获取ONU配置数据指配。但如果原故障PON口恢复后，需要给新开用户提供业务，但是由于ONU脏数据回收需要一定周期，已恢复的故障PON口上还是原来的ONU配置数据，ONU SN全部为非0值，无法为新接上来的ONU提供自动指配。此时，OLT可从离线的ONU中选择一个，将该离线ONU的配置数据视为一条SN号为0的数据资源，用其完成新上线ONU的配置数据指配。
本发明实施例还提供了一种光网络单元业务信息的发放装置，如图6所示，包括：
