Section: A.3 Representation in an information flow
Content: Invoking a service or service operation within an information flow is represented using a disaggregated representation (see figure A.3-1). The disaggregated representations on figure A.3-1 shall be used as follows: - The <step> represents the actual step number in the information flow e.g. ″7.″. - Representation a) shall be used when the step is required. - Representation b) shall be used when the step is optional or conditional. Figure A.3-1: Disaggregated representation of a NF service or service operation in information flows NOTE: Depending on the information flow, the order of NF Producer and NF Consumer can be reversed.
