4 Open Service Access APIs
The OSA specifications define an architecture that enables service application developers to make use of network
functionality through an open standardized interface, i.e. the OSA APIs. The network functionality is describes as
Service Capability Features or Services (see note). The OSA Framework is a general component in support of Services
(Service Capabilities) and Applications.
The OSA API is split into three types of interface classes, Service and Framework.
• Interface classes between the Applications and the Framework, that provide applications with basic
mechanisms (e.g. Authentication) that enable them to make use of the service capabilities in the network.
• Interface classes between Applications and Service Capability Features (SCF), which are individual services
that may be required by the client to enable the running of third party applications over the interface
e.g. Messaging type service.
• Interface classes between the Framework and the Service Capability Features, that provide the mechanisms
necessary for multi-vendorship.
• Interface classes between the Enterprise Operator and the Framework that provides the Enterprise Operator
with basic mechanisms to allow them to administer client application accounts and to manage their service
contracts and profiles.
These interfaces represent interfaces 1, 2, 3 and 4 of the figure 1. The other interfaces are not yet part of the scope of the
work.
