29.1983GPPOpen Service Architecture (OSA) Application Programming Interface (API) - Part 1Release 1999TS
For the purposes of this specification, the following definitions apply:
Applications: Services, which are designed using service capability features.
Gateway: Synonym for Service Capability Server. From the viewpoint of applications, a Service Capability Server can be seen as a gateway to the core network.
HE-VASP: Home Environment Value Added Service Provider. This is a VASP that has an agreement with the Home Environment to provide services.
Home Environment: responsible for overall provision of services to users
Local Service: A service, which can be exclusively provided in the current serving network by a Value Added Service Provider.
OSA Interface: Standardised Interface used by application to access service capability features.
Personal Service Environment: contains personalised information defining how subscribed services are provided and presented towards the user. The Personal Service Environment is defined in terms of one or more User Profiles.
Service Capabilities: Bearers defined by parameters, and/or mechanisms needed to realise services. These are within networks and under network control.
Service Capability Feature: Functionality offered by service capabilities that are accessible via the standardised OSA interface
Service Capability Server: Functional Entity providing OSA interfaces towards an application
User Interface Profile: Contains information to present the personalised user interface within the capabilities of the terminal and serving network.
User Profile: This is a label identifying a combination of one user interface profile, and one user services profile.
User Services Profile: Contains identification of subscriber services, their status and reference to service preferences.
Value Added Service Provider: provides services other than basic telecommunications service for which additional charges may be incurred.
Virtual Home Environment: A concept for personal service environment portability across network boundaries and between terminals.
