Access network service delivery using nested workflow process

The current issue for the access network service delivery is to swiftly accommodate newly generated service product by way of minimizing the influence caused by the change of the legacy system. Korea experienced the rapidly changing access network facility. In order to follow up rapidly changing environment, network service providers (NSP) have to develop the flexible and cost effective operations support systems (OSS). The service delivery management based on the conventional concepts is difficult to support the proper service delivery of the newly compound and cross-domain Internet services. Because of the severe competition among the service providers, the dense house pattern near the wire center, the governmental support, and the huge demands for Internet usage among the younger generation, the importance of the access network service delivery grows larger. We propose a nested workflow process for the cross domain Internet service with PM (provisioning model). Dividing into several subwork process and simplified master workflow for cross domain service delivery can manage the large scale and complex work into simple work and flow. Access network service delivery can be divided into several main jobs: service order classification, outside plant management, inside plant management, activation, facility service confirmation and send result to billing system. The nested hierarchical structure can balance the complexity and simplification. The OSS for access network service can manage the service installation at low cost and deliver the Internet services efficiently by choose and use appropriate provisioning models for each network models for the Internet service environments. If the automation of the service provisioning and the access equipment activation is possible based on the proposed idea, it completes the service requests for the Internet service installation across the domains in short time. And NSP can satisfy their customers. Moreover, NSP can save lots of expense and complete the service delivery without any physical works just by the automatic service activation of the provisioned access equipment ports on time that the customers require.
