scope:
The present document specifies the SI-SAP interface service and related primitives preliminarily defined in [1] and [7].
The scope of the document is twofold. On the one hand, revision of existing service specifications is carried out in order to reflect services' update demanded by current satellite systems. On the other hand, new services are defined in order to bridge the gaps in the following functional areas:
- Logon/logoff.
- Satellite Independent (SI) layer configuration.
- Group transmit.
Accordingly, the specification of new primitives for the aforementioned services is also provided in the present document.
Final notes about the use and the implementation of SI-SAP interface service primitives are provided as two independent annexes at the end of the present document. In more detail, illustration of SI-SAP interface and primitives' implementation in specific use-cases is given in the annex A. Details about the implementation of a SI-SAP interface in real satellite system are provided in the annex B, where the focus is on the SI-SAP interface implementation as i) local interface (mandatory) or ii) external interface to a BSM subsystem (optional).
