Figure 77 : Technical scenario –subscribe/unsubscribe/change by resident-parker.This technical use-case summarises how the resident parker interacts with the
Control Centre. Notice that the actions on the primary-service level are not part
of the PBL system. It has implications for manipulations and thus the interface
of the Virtual Enity Repository, but also for the VE Resolution, because in order
to extend a permit it first has to be located in the system.
On-street parking
This technical use-case summarises the actions triggered when time-parkers
and resident parkers actually park their car. Since the time-parking scenario is
of an ad-hoc nature (all pertinent actions conducted shortly prior to or during
parking), while the resident-parking scenario is of a recurring nature (payment
of fees, etc. well in advance to individual parking events), the former
incorporates many more use-cases then the latter. This technical use-case has
implications for the interface of the VE FC and the Security FC and the interface
the PBL exposes toward the PDM/webserver.
