In the design and planning process of the network, it is important to determine the optimal network structure according to the type of service to be provided, the demand size for each service, and the service providing area. However, in order to determine the optimal structure of the communication network, it is necessary to generate models of various communication networks according to the components of the communication network, the receiving zone of each component, and the hierarchical structure of the communication network, and to analyze the communication network model. This modeling and analysis process requires a lot of manpower and time. In the past, the service provided by the communication network, such as voice telephone network (PSTN), was solved by manual simplification of the model. .

Therefore, the accuracy and speed of the communication network modeling and analysis process, which takes most of the time and effort in the planning and design of the communication network, has become an important issue. However, since the conventional network modeling and analysis is a simple functional structure that is significantly different from the actual network structure in a manner that does not reflect the receiving area and the hierarchical structure of the network element, it is applied to a complex network for providing a plurality of services. The problem is that you can't.

An object of the present invention is to provide an apparatus and method for modeling a hierarchical communication network reflecting service information, information of communication network elements constituting a communication network, and information of a target area facility.

A user inputs a network element that accommodates a service and a subscriber and a network hierarchy that connects a receiving area and a receiving area of the network elements, thereby modeling the structure of the network. It is possible to accurately model the structure of the network under analysis, which changes according to the number of layers in the network, the type and location of network elements in the layer, the links between the network elements, and the receiving area where the communication elements in the lower layer are connected to the upper layer.

The inter-layer communication network setting unit 26 models the upper and lower connection links between the upper layer communication network element and the lower layer communication network element modeled by the layer-based communication network setting unit 24 based on the information stored in the data storage unit 10. That is, the range of the communication network element located in the lower layer accommodated by the communication network element located in the upper layer is set, and the type and transmission method of the connection link are set.

However, when there are a plurality of services provided by the communication network to be modeled, since the service types and demands are different for each service, the communication network optimized for each service is reflected by reflecting such relevant information stored in the data storage unit 10. It is preferable to design separately. In order to respond to such a demand, the modeling performing unit 20 of the present invention may further include a function of modeling a separate communication network for each service. The description thereof will be described later.

Preferably, the communication network modeling apparatus further includes a modeling result storage unit 30 to store the intermediate and final results of the communication network modeling performed by the modeling execution unit 20, and to model the intermediate and final results of the stored modeling It may be provided to the execution unit 20.
