ITU-T Q.1551

This Recommendation describes the application of INAP CS-1 (Refined) for UPT Service Set 1. It explains how to use INAP as defined in CS-1 Refinements to provide the UPT service. Clauses 1 to 3 contain general information including the Chosen architecture. Clause 4 describes the application contexts used for UPT. Clause 5 describes both the UPT information model and the UPT security model as used in SDF. In clause 6 the UPT specific behaviour of the SCF is described for every UPT procedures, using both a textual and an SDL description. Clause 5 constitutes the core part of the UPT Recommendation. The other clauses are included in this Recommendation because clause 5 is not in itself self-explanatory. The definition of the data model specifies (with some flexibility) the internetwork interface and as such should be considered as the main part of this Recommendation.
