Description

一种远端接入通信系统及其控制方法
技术领域
本发明涉及一种远端接入通信系统及其控制方法，属于网络通信技术领域。
背景技术
远端通信的接入网络是目前电信网络设备最重要的网络基础设施之一，是本地网络通信交换机与用户之间的连接设备，它负责将各种电信业务透明地传送到用户。各种业务网络要向最终用户提供的各种服务大多都是通过接入网络来实现的，因而接入网络必须满足各种业务网络对用户的接入要求和用户对业务需求的广泛性要求。未来的接入网络将是提供大容量、高速率、高质量的综合业务(数据、视频、语音、多媒体等)接入网络。
一般远端接入通信系统位于电信网络的末端，是电信网向用户提供业务服务的窗口。远端接入通信系统覆盖从业务提供点至用户终端之间的所有设备和传输媒介。参考图1所示，目前的远端接入通信系统一般主要是由配线架(MDF-Main Distribution Frame)、远端接入设备(ANU-Access Network Unit)和其他辅助设备组成。所有设备模块放置在一个机柜里面，通过电缆或者光缆实现与外面的连接。远端接入设备完成用户通信数据的接入，在设备内部转换或者汇聚后通过上行接口送入上层网络。配线架实现通信设备端口到外面用户线路的映射。
配线架存在于网络设备和用户终端之间，负责从设备电缆到用户电缆的匹配连接。MDF由外线模块(水平模块)、内线模块(垂直模块)以及连接外线模块和内线模块之间的连线构成，通过选择线路之间的不同连接，实现内线模块端口和外线模块端口之间的对应。
远端接入设备可以为本地交换机、窄带接入设备、数字用户接入复用器(DSLAM-Digital Subscriber Line Access Multiplexer)接入设备、光纤接入设备，还包括可以同时接入窄带业务和宽带业务的综合接入设备。
其他的辅助设备包括设备电源系统(主用电源和备用电源系统)、温度调节设备、告警设备等。电源系统为远端接入设备和配线架提供工作所用的电源。一般电源系统有主备两个模块。主用模块为一次电源，把市电通过电压变换得到系统工作所用电源；备用模块一般为蓄电池组，在市电故障时为通信设备提供所需电源。温度调节设备负责调节室外机柜里面的温度，保证机柜内环境温度符合远端接入设备、配线架等设备的运营要求。告警设备监控机柜内部所有设备的运行情况，以及其他如湿度、温度、水浸等。
随着技术的发展，E1接入、光纤接入等已经成为接入领域的通用接入手段，而配线架对应技术的发展，也有了数字配线架(DDF)、光纤配线架(ODF)。但是当远端接入设备在新用户业务发放、现有用户新业务选择、移机、改号等维护时，一般的方法是：首先修改用户在设备里面的配置数据，然后更改配线架上面内线模块和外线模块的对应关系，实现功能的改变。
目前，远端接入通信系统一般可以放在户外、大路边、地下室等。当开通新用户或用户增加新需求时，维护人员到遥远的现场进行放号，通过MDF进行跳线开通来满足用户的需求。即使只有单一用户的需求或开通新业务时也需专程前往维护操作。如此频繁的、大量的维护操作，导致人工成本很高。更关键的是所有的业务发放均不能即时进行，业务发放等操作需要较长的流程和周期，对用户的服务响应和服务质量难以提升。
发明内容
本发明针对上述现有技术中存在的远端接入通信系统维护繁琐、人工成本高、业务发放不能即时进行等缺点，提出了一种远端接入通信系统及控制方法。本发明的技术方案如下：
一种远端接入通信系统，包括自动配线架(AMDF-Automated MainDistribution Frame)、远端接入设备以及设备管理系统，所述自动配线架和远端接入设备在设备管理系统的控制下，完成用户设备接口到远端接入设备接口的端口自动对应，从而完成自动交换功能。
在本发明中，所述自动配线架包括矩阵交换模块、分别与所述矩阵交换模块连接的接线侧模块和出线侧模块、以及与上述三个模块连接的用于启动和配置自动配线架的自动配线架控制器，所述接线侧模块的输入端通过电缆与用户设备连接，所述出线侧模块的输出端通过电缆与远端接入设备连接。
所述的远端接入设备为本地交换机。
所述的远端接入设备为窄带接入设备或宽带接入设备。
所述的远端接入设备为DSLAM接入设备。
所述的远端接入设备为光纤接入设备。
本发明还提供了一种远端接入通信系统控制方法，在用户设备和远端接入设备之间设置自动配线架，所述自动配线架和远端接入设备在设备管理系统的控制下，完成用户接口到设备接口的端口自动对应，从而完成自动交换功能。
上述完成用户接口到远端设备接口的端口自动对应的步骤如下：
1)用户有业务需求时，所述设备管理系统向所述自动配线架下发配置命令；
2)自动配线架收到配置命令后，对所述配置命令的合法性进行核实；
3)如果核实成功，自动配线架根据该命令配置其矩阵交换模块，以实现用户通信端口与远端设备端口的对应；
4)如果核实失败，自动配线架向设备管理系统给出告警，设备管理系统根据该告警反馈判断是重新下发命令，还是进行其它操作。
在本发明中，所述对配置命令的合法性核实方法包括自动配线架控制器核实命令字段内容的真伪的步骤。
在本发明中，所述对配置命令的合法性核实方法包括检查命令字段配置数据的合理性的步骤。
在本发明中，所述对配置命令的合法性核实方法包括检查命令字段数据的完整性的步骤。
在本发明中，所述设备管理系统通过网管向所述自动配线架下发配置命令。
与现有技术相比，本发明具有如下显著优点：
1.降低了运营成本。远端接入通信系统的关于跳线部分的操作，可以直接通过设备管理系统的远程控制快速实现，既减少了时间，又不用安排业务人员到现场操作，从而大大减少了网络的运营维护成本和人工成本；
2.提高了业务发放的速度。由于是用网管操作代替了人工现场操作，以往几天的工作很可能在几分钟之内完成，大大提高了通信的业务发放速度。
3.由于采用了自动配线架与远端接入设备连接，自动配线架跳线一次完成，避免了传统方法多次无规则跳线造成的混乱，使配线架外观美观整齐。
4.由于采用设备管理系统，可以在本地或通过网管系统进行简单的操作就可完成遇移机、改号和工程倒线时的跳线工作，简化了多次跳线的工作；也避免了配线架因卡接点经多次卡接而造成卡点多次操作引起的松弛脱落问题，减少了故障的发生。
附图说明
图1为现有技术中远端接入通信系统构成示意图；
图2为本发明的实施例所述的远端接入通信系统的方框图；
图3为本发明所述控制方法的流程框图；
图4为本发明实施例中应用模式的示意图；
图5为本发明实施例中应用模式的另一示意图。
具体实施方式
下面结合附图和具体实施例对本发明作进一步的介绍，但不作为对本发明的限定。
如图2所示，本发明所述的一种远端接入通信系统，包括自动配线架、用于将各种电信业务透明地传送到用户的远端接入设备，以及设备管理系统，所述自动配线架和远端接入设备在设备管理系统的控制下，完成用户设备接口到远端设备接口的端口自动对应，从而完成自动交换功能。
所述自动配线架包括矩阵交换模块、分别与所述矩阵交换模块连接的接线侧模块和出线侧模块，以及与上述三个模块连接的用于启动和配置自动配线架的自动配线架控制器，所述接线侧模块的接线输入端口通过电缆与用户设备连接，所述出线侧模块的输出端口通过电缆与远端接入设备连接。
在实际应用中，远端设备端口和用户端口之间可能存在一定的收敛比，这可以在AMDF上面通过配置端口来实现。
远端接入设备是电信网向用户提供业务服务的窗口，它可以是本地交换机、窄带接入设备、宽带接入的设备、DSLAM接入设备、光接入的传输设备或者上述混合组合的设备，如同时接入窄带业务和宽带业务的综合接入设备。它负责将各种电信业务透明地传送到用户，解决用户的接入、业务的发放和业务的切换。
本发明还提供了一种利用上述远端接入通信系统进行控制的方法，具体步骤如下：
1)用户有业务需求时，所述设备管理系统通过网管向所述自动配线架下发配置命令。
2)自动配线架收到配置命令后，首先核实配置命令的合法性，包括核实其中命令字段内容的真伪，检查命令字段配置数据的合理性以及命令字段数据的完整性等步骤。如果核实成功，自动配线架根据该命令配置其矩阵交换模块，以实现用户接口到远端设备接口的端口自动对应。如果核实失败，自动配线架不工作，并向设备管理系统给出告警，说明收到非法命令，设备管理系统根据该告警反馈判断是重新下发命令，还是进行其它操作。
下面以目前在网上大量应用的电话系统为例，对本发明所述系统的自动配线方法进行说明。如图3所示，大量用户终端通过双绞线连接到AMDF的接线侧模块上，即把用户板的通信电缆连接到AMDF的一侧端口，如果用户B(3-6、4-5用户线)想开通一般的宽带业务，可由设备管理系统通过本地网管或远程网管下发配置命令。AMDF收到该配置命令后，首先核实配置命令的合法性，包括核实其中命令字段内容的真伪，命令字段配置数据的合理性，以及命令字段数据的完整性等步骤。核实成功后，根据该命令配置其矩阵交换模块，将用户B一侧(即接线侧模块一侧)的线3-6、4-5与远端接入设备一侧(即出线侧模块一侧)的线11-14、12-13相对应的线连接起来。即把该用户的双绞线连接到设备电缆的某个端口上面，实现用户终端设备到远端接入设备的连接，与ANU互通来达到开通用户的业务目的，从而实现业务的发放。设备控制系统的管理软件可以在AMDF的现场通过AMDF管理配置接口直接在本地进行业务管理，也可以在远端进行管理业务发放，达到实现业务的自动发放。
远端管理是指利用ANU通信设备、自动配线架内部提供的业务上行通道、完成对设备管理、业务发放、维护等，信息通过业务通道提供给网管系统。ANU通信设备提供网管接口，使用简单网络管理协议(SNMP-Simple NetworkManagement Protocol)与ANU通信设备、自动配线架通信。
PC服务器采用本地或远端客户端-服务器体系结构，可以方便地实现本地网管和集中网管。
当远端接入设备接入了较多的用户的时候，机柜空间可能会成为应用的瓶颈。在这种情况下，可以采用下面两种方式来解决：
其一：参考图4所示，当容量达到一定数量以后，受机柜容量的限制，远端接入设备和自动配线架可能会放置到两个机柜里面，之间通过电缆连接。
其二：参考图5所示，当容量再增大的时候，所有设备可以被安装到一个路边的小房子里面应用。设备间逻辑关系不变。
