摘要
构建资源信息模型是运营商对电信网络中资源进行有效管理的基础和前提。提出了一种以组网方式为基础,以端口为核心的电信网络资源建模方法。该方法将建模过程分为确定网络、识别节点、标识连接、细化设备、描述能力、空间发现以及模型描述7个步骤,并给出了挖掘实体间关系的详细流程。以该建模方法为指导,构建了LTE资源信息模型,证明了建模方法的有效性。并且,从类的复杂度、继承树深度宽度比和类间耦合性几个方面对所构建的LTE信息模型进行了客观评价,结果表明该模型具有较高的质量。
Based on the well designed resource information model, the telecom operators can effectively manage the te]ecom network resource. A resource modeling methodology was proposed. The modeling methodology was based on the network topology and the port. The modeling process was divided into seven sub-processes： network analysis, network node identification, connection identification, equipment description, ability description, space resource analysis and model expression. In addition, a discussion on the relationships between entities had been made. Based on the modeling methodology, the LTE resource information model was constructed. Therefore, the validity of the modeling methodology was proven. Moreover, the LTE resource information model was objectively evaluated through three aspects： the complexity of the class, the ratio of depth and width of the inheritance tree and the coupling degree between classes. Results show that this model is high-quality.
