Description

一种在光网络中传输信息的方法、终端及系统 技术领域
本发明涉及移动通信技术领域,特别涉及一种在光网络中传输信息的方法、终端及系统。
背景技术
光纤接入(Fiber To The x,简称FTTx)是一种接入网络光纤化技术,范围从区域电信机房的局端设备到用户端设备,局端设备为光线路终端(Optical Line Terminal,简称OLT),用户端设备为光网络单元(Optical Network Unit,简称ONU)或者光网络终端(Optical Network Terminal,简称ONT)。根据光纤接入的类型不同,ONT可能会被安装到用户家中、大楼、路边机箱或住宅小区等位置。
随着光纤接入的大规模商用,ONT的功能特性在不断的增强,现网存量的ONT和ONT安装的需求也越来越多,在ONT安装和运维时常常会遇到如下问题:
由于各个国家和地区规划和开展的数据业务和语音业务都不相同,因此在不同的国家和地区安装ONT时,需要人工确定或者选择所述ONT的地理位置信息来加载对应的配置参数,以进行设备注册,导致ONT的安装效率低下。
此外,如果安装人员在安装ONT时需要检测线路质量,在ONT没有开通业务之前,只能通过ONT查询光路下行质量,对于光路上行质量,则需要人工联系OLT侧的管理人员。同样,如果安装人员发现存在OLT光模块口连接错误的问题,不仅要花费大量的时间和精力去人工排查是哪个光模块口连接错误,还要人工联系OLT侧的管理人员进行信息核对,同样使得ONT的安装效率低下。
ONT在开通业务之后,还会由于各种原因,例如软件故障(bug),出现脱管问题,即在线路正常的情况下,无法响应OLT发送的消息。这种情况下,现有技术需要运维人员到ONT所处的地理位置人工采集ONT的故障信息,再根据采集到的故障信息进行问题定位,使得问题定位的效率非常低。

具体实施方式
为使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明实施方式作进一步地详细描述。
为了便于理解本发明实施例,首先对吉比特无源光网络(Gigabit Passive Optical Network,简称GPON)的基本网络结构和GPON传输汇聚(GPON Transmission Convergence,简称GTC)层系统协议栈进行一个简单的说明。
GPON是国际电信联盟远程通信标准化组织(International Telecommunication Union Telecommunication Standardization Sector,简称ITU-T)提出的一种灵活的吉比特光纤接入网,支持商业和居民业务的宽带全业务接入,是一种新的PON技术。
图1为一种示例性的GPON基本网络结构,从右到左依次包括光线路终端OLT、ODN、光网络终端ONT、网络终端(Network Termination,简称NT)、家庭网络(Home Network,简称HN)和终端设备(Terminal Equipment,简称TE)。其中,OLT、ODN和ONT之间通过PON接口连接,ONT和NT之间通过各种类型的数字用户线路(x Digital Subscriber Line,简称xDSL)连接,ONT和HN、HN和NT之间通过用户网络侧接口(User Networks interface,简称UNI)连接。HN可以为家庭安装的路由器,TE可以为笔记本电脑、平板电脑、手机、电话机等。图中的实线表示物理线路,虚线表示ONT管理和控制系统线路。
本发明实施例中将ONU或者ONT都视为用户端设备,不做区分,除非有 特殊说明,本发明实施例使用“ONT”来指示ONU和ONT。
图2为GTC层系统协议栈,由GTC成帧子层(GTC Framing Sub-layer)和TC适配子层(TC adaptation Sub-layer)组成。
GTC的控制/管理平面(C/M-plane)包括OMCI、嵌入式操作管理维护(Operations Administration and Maintenance,简称OAM)和PLOAM,其中OMCI管理GTC上层所定义的业务。嵌入式OAM通道由格式化的GTC帧头提供,嵌入OAM通道的每个信息直接映射到GTC帧头中的特定区域,为对时间敏感的控制信息提供了一条低时延通路。PLOAM通道是由GTC帧内指定位置承载的一个格式化的信息系统,它用于传送其他所有未通过嵌入式OAM通道发送的物理媒质相关(Physical Media Dependent,简称PMD)和GTC管理信息。
GTC的用户平面(U-plane)包括异步转移模式(Asynchronous Transfer Mode,简称ATM,图中未示出)和GPON封装模式(GPON Encapsulation Method,简称GEM),GEM Client承载GEM数据流,例如视频数据和语音数据等。
接下来介绍一种示例性的ONT安装流程。首先将ONT上电,然后将已经连接ODN的光纤插入ONT,此时PLOAM通道开始工作,等ONT进入运行状态后,OMCI通道开始工作,OLT通过OMCI通道向ONT发送OMCI业务配置消息,ONT完成OMCI业务配置后,进行以太网上的点对点协议(Point-to-Point Protocol over Ethernet,简称PPPoE)拨号,向网络管理服务器发送开通业务请求,网络管理服务器接收到开通业务请求后,将业务模板通过OLT配置到ONT上,ONT配置完业务模板后即开通了业务,可以传输数据业务和语音业务,至此ONT安装完成。
本发明实施例中将处于运行状态的ONT称为激活或者在线ONT,不处于运行状态的ONT称为未激活或者未上线ONT;将完成OMCI业务配置的ONT称为配置恢复完成的ONT,将未完成OMCI业务配置的ONT称为配置恢复中的ONT。
在对技术问题的研究中发现,在安装ONT时,如果安装人员需要一些安装信息(安装信息包括但不限于该ONT的地理位置信息、该ONT和OLT之间距离信息、光路上行质量、网络拓扑等信息)来配置ONT或者排查线路连接错误时,由于此时ONT还未激活或者处于配置恢复中,因此OLT无法将ONT所需的安装信息通过OMCI通道发送给ONT。此外,由于嵌入式OAM支持的字符 长度有限,只能完成带宽授权、密钥交换、动态带宽分配等特定的功能,因此也无法用来传输上述安装信息。为解决上述技术问题,本发明实施例通过PLOAM通道来传输安装ONT所需的信息。
图3为本发明实施例一提供的一种在光网络中传输信息的方法的流程图,包括如下步骤:
S31:OLT接收ONT通过PLOAM通道发送的SN;
每个ONT都有一个能够唯一标识该ONT的序列号,ONT通过PLOAM通道将其序列号发送给OLT。
S32:OLT为所述ONT分配一个标识(ID),所述ID和所述SN相对应;
由于一般情况下SN需要占用较多的字节,因此OLT会为ONT分配一个ID,该ID和ONT的SN相对应,OLT使用该ID来唯一的标识该ONT。
S33:OLT通过所述PLOAM通道向所述ONT发送第一消息;
其中,第一消息携带所述ID,并且携带安装信息,该安装信息包括以下之一:OLT的地理位置信息、光路上行质量信息、测距信息和OLT设备描述信息。
根据各个国家和地区的不同情况,OLT的地理位置信息可以包括以下至少之一:OLT所在国家的国家码(以下简称为OLT的国家码)、所在地区的地区码(以下简称为OLT的地区码)和所在省份的省份编号,其中省份编号可以参考邮政编码设定,本发明实施例对此不做限定。光路上行质量信息可以根据OLT上行帧定界错误来确定。测距信息是指ONT和OLT之间的距离。OLT设备描述信息包括以下至少之一:OLT的框ID、槽位号、光模块口ID和IP地址。
OLT的产品形态通常为机柜中的一个机框,每个机框包含多个槽位,每个槽位对应一个单板,每个单板包含多个光模块口,每个光模块口可以连接一个ODN,每个ODN连接多个ONT。OLT的IP地址可以为IPV4地址或者IPV6地址。
第一消息可以为私有消息或PON-ID消息,当第一消息为PON-ID消息,并携带OLT设备描述信息时,一种示例性的PON-ID消息格式如表1所示:
表1
Figure PCTCN2014095397-appb-000001
Figure PCTCN2014095397-appb-000002
表1中的Octet表示字节编号,Content表示字节的内容,Description表示字节的描述。第1-3字节和第11-12字节的内容和描述在现有的GPON标准中已经有规定,本发明实施例对第4-10字节的内容和描述进行了扩展。当PON-ID消息第4字节的内容为00000003时,表示该PON-ID消息携带OLT的框ID、槽位号和光模块口ID,并通过第5-7字节携带这些信息。
需注意的是,表1中第4-10字节的内容和描述仅是示例性的,本发明实施例中可以通过PON-ID消息的第4-10字节中的任意一个字节表示所携带的安装信息的类型,并通过至少一个其余字节描述该安装信息。
当一个字节无法完整描述该字节的内容时,还可以用两个字节,一个低字节和一个高字节来一起描述该字节的内容。各种安装信息所占用的字节根据安装信息的编码方式不同而不同。
当第一消息携带OLT的地理位置信息时,一种示例性的PON-ID消息格式如表2所示:
表2
Figure PCTCN2014095397-appb-000003
Figure PCTCN2014095397-appb-000004
表2中当PON-ID消息第4字节的内容为00000005时,表示该PON-ID消息携带OLT的国家码,并通过第5字节携带这些信息。
表2中第4-10字节的内容和描述仅是示例性的,本发明实施例中可以通过PON-ID消息的第4-10字节中的任意一个字节表示所携带的安装信息的类型,并通过至少一个其余字节描述该安装信息。
当一个字节无法完整描述该字节的内容时,还可以用两个字节,一个低字节和一个高字节来一起描述该字节的内容。各种安装信息所占用的字节根据安装信息的编码方式不同而不同。
OLT可以通过发送多个PON-ID消息来发送多个安装信息。当第一消息为私有消息时,OLT可以通过私有消息一次性发送多个安装信息。
S34:ONT保存安装信息;
ONT接收到OLT发送的第一消息后,可以将第一消息携带的安装信息缓存到其内存中,也可以保存到其闪存Flash或硬盘中。
ONT保存了第一消息携带的安装信息以后,安装人员就可以通过电脑登陆ONT的IP地址,在ONT的信息界面上直接浏览这些信息。
图4为一种示例性的自动显示光路上行质量信息、测距信息和OLT设备描述信息的信息界面,例如,“PON口标识”查询值中的“10.167.215.55”表示OLT的IP地址,“0/2/3”表示第0个机框的第2个槽位的第3个光模块口。
安装人员可以根据这些信息来安装ONT,例如,若信息界面显示的OLT设备描述信息和ONT实际连接的OLT不一致,有可能是ODN连接错误,需要重新连接;若信息界面显示的测距信息大于参考值,则说明当前网络布线不合理,需要调整布线方式;若多次登陆后,信息界面的帧定界错误一直在增加,则说明上行线路质量过差,可能需要更换OLT的PON光模块。
图5为一种示例性的自动显示OLT地理位置信息的信息界面,当安装人员通过特定IP地址登陆ONT后,能够直接浏览OLT地理位置信息,进而根据该地理位置信息加载相应的配置参数。
本发明实施例一中,OLT通过PLOAM通道将安装ONT所需的安装信息发送给ONT,使得ONT能够快速并且自动的获取到需要的安装信息,提高了ONT的安装效率。
图6为本发明实施例二提供的另一种在光网络中传输信息的方法的流程图,和实施例一的主要区别在于,本实施例中OLT将其地理位置信息广播给其连接的所有ONT,无需ONT上报SN。包括如下步骤:
S61:OLT检测到有ONT接入ODN;
该ONT可以为初次安装的ONT,也可以为断线后重新接入ODN的、已经开通业务的ONT。
可选地,只要OLT检测到上行线路有光信号,即认为检测到有ONT接入ODN。
如无特殊说明,本发明实施例中的ODN是指OLT和ONT之间的光分配网络。
S62:OLT通过PLOAM通道向该OLT连接的所有ONT广播该OLT的地理位置信息;
可选地,OLT周期性地通过PLOAM通道向所有ONT广播该OLT的地理位置信息,例如,该周期可以为60秒。
可选地,OLT通过发送私有消息或PON-ID消息来广播地理位置信息,具体的消息描述和实施例一中的S33相同,此处不再赘述。
S63:ONT保存该OLT的地理位置信息;
ONT接收到OLT发送的OLT的地理位置信息后,可以将该信息缓存到其内存中,也可以保存到其闪存Flash或硬盘中。
ONT保存了OLT的地理位置信息以后,安装人员就可以通过电脑登陆ONT的IP地址,直接浏览OLT所处的国家、地区和省份。
本发明实施例二中,OLT一检测到有ONT接入ODN就向其连接的所有ONT广播其地理位置信息,使得ONT能够快速并且自动的获取到OLT的地理位置信 息,提高了ONT的安装效率。
图7为本发明实施例三提供的另一种在光网络中传输信息的方法的流程图,包括如下步骤:
S71:OLT通过OMCI通道向ONT发送指令;
可选地,该指令为指示ONT重新启动的重启指令,或者是通过OMCI通道查询ONT信息的查询指令。
S72:若OLT在预设时间内未接收到对所述指令的响应,OLT通过PLOAM通道向所述ONT发送故障收集指令;
该预设时间可以根据实际情况灵活设定,例如设定为1秒,本发明实施例对此不作限定。
在线或已激活的ONT会由于软件故障(bug)或者网络存在流氓ONT(rogue ONT)等原因导致ONT脱管,无法响应OLT通过OMCI通道发送的指令。
所述故障收集指令用于指示所述ONT将其故障信息保存在非易失性存储器上。非易失性存储器是指断电后不会丢失信息的存储器,例如闪存Flash、硬盘等。该非易失性存储器可以位于ONT的内部,也可以位于ONT的外部。
可选地,该故障信息包括ONT的日志(log)、当前运行配置和异常调用栈中的至少之一。通常情况下故障信息都缓存在其内存上,内存是一种易失性存储器,断电后故障信息就会丢失,本发明实施例中通过指示ONT将故障信息保存在非易失性存储器上,可以避免丢失故障信息。
可选地,该故障收集指令携带在私有消息或PON-ID消息中,当故障收集指令携带在PON-ID消息中时,一种示例性的PON-ID消息格式如表3所示:
表3
Figure PCTCN2014095397-appb-000005
Figure PCTCN2014095397-appb-000006
表3中当PON-ID消息第4字节的内容为00000001时,表示该PON-ID消息携带故障收集指令,并通过第5字节表示将故障信息保存至Flash。
表3中第4-10字节的内容和描述仅是示例性的,本发明实施例中可以通过PON-ID消息的第4-10字节中的任意一个字节表示携带携带故障收集指令,并通过至少一个其余字节表示故障收集指令的内容,例如将故障信息保存至Flash或硬盘,或重新启动ONT。
当一个字节无法完整描述该字节的内容时,还可以用两个字节,一个低字节和一个高字节来一起描述该字节的内容。故障收集指令所占用的字节根据故障收集指令编码方式的不同而不同。
S73:ONT根据故障收集指令存储故障信息;
S74:ONT向OLT发送确认消息;
该确认消息表示ONT已经将故障信息保存至非易失性存储器,如Flash或硬盘;
S75:OLT通过PLOAM通道向ONT发送重启指令;
该重启指令用于指示ONT重新启动,还可以同时指示ONT恢复出厂配置。
S76:ONT将故障信息通过该OLT发送给网络管理系统。
ONT重新启动后,可以通过OMCI通道将故障信息上报给网络管理系统。如果ONT重新启动后,依然处于脱管状态,OLT可以指示ONT恢复出厂配置,然后再通过OMCI通道将故障信息上报给网络管理系统。
本步骤之前,OLT可以先指示ONT将故障信息通过该OLT发送给网络管理系统。
本发明实施例三中,OLT检测到ONT脱管时,OLT通过PLOAM通道向ONT发送故障信息收集指令,使得ONT将故障信息保存在非易失性存储器中,避免了ONT断电后故障信息丢失,便于远程获取故障信息后进行问题定位或复现,提高了解决ONT脱管问题的效率。
