LSO Sonata (BUS:BUS) belongs to the family of LSO Interface Reference Points (IRP) as defined in MEF 55.1. It defines the management reference point supporting the management and operations interactions (e.g., serviceability, ordering, billing, trouble ticketing, etc.) between two network providers (e.g., Service Provider and Partner Domain). In other words, LSO Sonata supports non-control cross domain interactions between the Service Provider's Business Applications and the Partner's Business Applications.
LSO Sonata connects between the BSS functions of the Service Provider domain and the Partner domain respectively and connects 'East-West' in parallel to LSO Interlude.
Service Provider browses the Partner's product catalog (e.g. wholesale catalog) for Product Offerings that are available for the Service Provider to select. This may include some geographical and service information to support availability queries of a Product Offering in a specific geographical area.
Service Provider develops (based on Product Offerings), places, tracks, and changes Product Orders with the Partner.
Service Provider requests modification of Product Instances.
Service Provider receives Product Instance performance and fault information provided by the Partner.
Service Provider receives information from the Partner about the scheduled maintenance that may impact their Product Instances.
Service Provider places and tracks trouble reports.
Service Provider exchanges usage and billing information.
LSO Sonata APIs
MEF is standardizing LSO Sonata APIs as part of a comprehensive effort to standardize multiple sets of LSO APIs enabling service automation across providers and over multiple network technology domains. In the context of LSO, API describes the Management Interface Reference Point along with a data model, the protocol that defines operations on the data and the encoding format used to encode data according to the data model. LSO Sonata APIs relate to the interface reference point within the LSO Reference Architecture that supports business-to-business interactions between service providers. The full suite of planned LSO Sonata APIs deals with the following business functionalities.
