23.5023GPPProcedures for the 5G System (5GS)Release 18TS

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.
