北向接口业务开通功能的设计与实现

Design and Implementation of Service Provisioning in TL1 Northbound Interface

近几年,运营商越来越多的使用第3方网管对不同厂商设备进行统一业务开通,而第3方网管和设备EMS之间一般使用北向接口并采用TL1协议。为了满足需求,在研究北向接口中业务开通接口(I1)的基础上,结合现有设备提出了业务自动开通功能的整体设计框架、具体模块划分,并逐个论述各个模块的设计与实现的方式。本文采用多线程的管理方式进行命令的分派,实现多网元间预配置数据的并行处理;采用ONU授权和业务配置分开的管理方式便于ONU在线和离线时配置的下发。最后使用Se-cureCRT6.0进行仿真测试,仿真结果表明该方案能够按照运营商的TL1标准进行业务开通,适合现网的无源光网络接入系统。

In recent years, the Internet Service Provider use the third-party network management to provide services uniformly for different devices, and the third-party network management and the EMS device is connected by the TL1 northbound interface . In order to meet the requirements, the service provides interface of the TL1 northbound interface, and offer the whole design frameworks and partitioning of models of the service providing systems based on our devices,and also discuss the methods to design and realize. This paper achieves Pre-configured data-parallel processing in many network elements by using the multi-threading management method; and makes the serviced easily distribute either ONU online or offline by using the managements of dividing the ONU authority from configurations. Finally, we use the SecureCRT6.0 to simulate, the results indicate that we can meet the requirements, and the method fits the passive optical network access system of current network.
