ABSTRACT
The environment in which services are provisioned in existing networks has a number of
shortcomings. Neither the service domain nor the services therein have a standardised
structure. Signalling between terminals and services uses network protocols that are
inappropriately oriented towards bearer management. The control of bearer connections,
and the view of call states, is maintained in the network layer, making bearer
management difficult and limited.
A service-centric service provisioning environment is proposed, which advocates a
structured service domain, and a structured approach to service development and
provisioning. A direct communication path between terminals and services at the
application layer, that utilises high-level, service-oriented protocols, is proposed. Control
of the call / session layer and the bearer network, and view of connection states is
relocated to the application layer, facilitating bearer manipulation by services located in
the service domain.
It is shown that the capabilities and features of services provisioned in the proposed
service provisioning environment are of a greater range, more advanced and more
complex. It is also shown that the proposed service provisioning environment brings
about potential efficiency gains for the initiation of 2-party calls, and significant
efficiency gains for the initiation of multiparty calls.
