For CSPs, provisioning services for enterprises typically involves lengthy, customized development and numerous offline processes, with limited reusability. To address these challenges, CSPs need a standardized design and automated orchestration to rapidly integrate business and operational support systems (BSS and OSS) to meet the needs of enterprise customers. This Catalyst will develop an approach based on PSR (product-service-resource) to lower the ready-to-launch time from months to minutes and achieve an 80% improvement in service development efficiency. By adopting a modular design, automated algorithms, and flexible assembly of atomic services, CSPs can better adapt to diverse business needs, improve flexibility and scalability, reduce risks, optimize resource usage, and automate operation and maintenance management. Drawing on the TMF GB922 specification, the Catalyst will use a hierarchical decoupling method to design telecoms products rapidly by reusing objects and capabilities prepared at lower levels, eliminating the need to start from scratch each time. The Catalyst will also convert the contents of service design into a unified IT language and distribute it in the form of orchestration packages, which can be automatically loaded and compiled by the OSS. At the same time, it will employ a PSR-based automatic generation algorithm to further optimize service design efficiency. This algorithm will be designed to reduce labor costs and network/device configuration learning costs, and streamline the overall process. The Catalyst will use a number of metrics to track its progress. For example, the effectiveness of the PSR modeling approach can be measured by tracking component reusability, while the readiness of each system's capabilities can be measured by the one-time success rate of service provision. Similarly, the effectiveness of PSR-based service design can be measured by tracking the service development cycle. Decoupling OSS and standardizing network capabilities should help CSPs' network management systems to achieve better fault and performance management, as well as faster service provision. Moreover, enterprises will be able to develop new applications based on these network capabilities, and accelerate application innovation and the digital transformation of their industry.
