The enterprise concepts of enterprise objects
fulfilling roles of performative ac
tions are used to describe the multiparty
service orchestration
inherent in the system concept desc
ribed above. The roles that the
stakeholders in location-based
services can play with respect to a service are
user, broker or provider. For the application and
supporting service broker system, this specificati
on results in the identification of consumer objects
(users) and of objects managing these users through
applications (service brokers and application
provider). For the supporting network infrastructu
re, a service provider object manages the binding
object.
