BACKGROUND OF THE INVENTION
The present invention relates to an optical access device selection operation support system (OSS) for selecting an optical access device that constitutes an optical access system that provides a communication service.
[0002]
[Prior art]
Optical access devices installed on the service provider side such as a network operator, for example, STM-OLT (Synchronous Transfer Mode-Optical Line Terminal), and optical installed on the user side When a service provider provides a telephone communication service or an IP communication service to a user using an optical access system including an access device such as an ONU (Optical Network Unit: optical subscriber line network device), the optical access Although it is necessary to select an optical access device corresponding to the communication service by using the device selection OSS, since there were few types of communication services in the past, an OSS equipped with an optical access device selection logic for each communication service was constructed. And this was used.
[0003]
[Problems to be solved by the invention]
However, with the recent spread of IP communication services, many new communication services and ONU types have increased. For this reason, with the above-described conventional technology, a new OSS is required every time the type of communication service or ONU increases, or a modification of the OSS is required, which requires development cost, development time, and introduction cost. There was a problem.
[0004]
An object of the present invention is to add a communication service by selecting an optical access device and managing conditions and parameters necessary for device control as a correspondence table in order to provide the communication service using the optical access system. Or an optical access device selection OSS that facilitates an increase in the type of optical access device.
[0005]
[Means for Solving the Problems]
The present invention relates to an optical access device selection OSS provided with a database for managing equipment usage information related to an optical access device, and a correspondence table between communication service types and device selection logic considering equipment accommodation conditions that differ for each communication service type. From the correspondence table between the types of optical access devices and the parameters required for control depending on the type of optical access device, the device-specific parameters required for capacity calculation are determined. To obtain information on the equipment that can be accommodated. In addition, for equipment that has been confirmed to be accommodated, a command required for device control is generated from a correspondence table between the types of optical access devices and parameters required for different types of optical access devices. The communication service is opened by controlling the access device.
[0006]
When the types of communication services and optical access devices increase, the correspondence table between the types of communication services and the device selection logic that takes into account the equipment accommodation conditions that differ for each type of communication services, and the types of optical access devices and optical access devices By adding new data to the correspondence table with the parameters required for different control for each type, it is possible to easily cope with it.
[0007]
In the conventional technology, since the OSS is divided for each communication service, the communication service, the device selection logic, the optical access device, and the parameters necessary for the control are associated with each other one by one, and the information is held as a database. In the present invention, it is possible to associate the communication service, the device selection logic, and the optical access device with the parameters required for the control in a many-to-one or one-to-many manner, and keep the correspondence table as a correspondence table separately from the database. The difference is that communication services can be easily added and the types of optical access devices can be easily increased by adding or changing data in the network.
