3.1 Definitions
For the purposes of this TS, the following definitions apply:
Basic telecommunication service : this term is used as a common reference to both bearer services and teleservices.
Bearer service : is a type of telecommunication service that provides the capability of transmission of signals between access points.
Call : a logical association between several users (this could be connection oriented or connection less).
Connection : is a communication channel between two or more end-points (e.g. terminal, server etc.).
Mobile termination : the mobile termination is the component of the user equipment which supports functions specific to management of the radio interface (Um).
Multimedia service : Multimedia services are services that handle several types of media. For some services, synchronisation between the media is necessary (e.g. synchronised audio and video). A multimedia service may involve multiple parties, multiple connections, and the addition or deletion of resources and users within a single call.
Nomadic Operating Mode : Mode of operation where the terminal is transportable but being operated while stationary and may in addition require user co-operation (e.g. close to open spaces, antenna setup…).
Quality of Service : the collective effect of service performances which determine the degree of satisfaction of a user of a service. It is characterised by the combined aspects of performance factors applicable to all services, such as;
service operability performance;
– service accessibility performance;
– service retention performance;
– service integrity performance; and
– other factors specific to each service.
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 application interface
Services: Services are made up of different service capability features.
Supplementary service : is a service which modifies or supplements a basic telecommunication service. Consequently, it cannot be offered to a user as a standalone service. It shall be offered together with or in association with a basic telecommunication service. The same supplementary service may be common to a number of basic telecommunication services.
Teleservice; is a type of telecommunication service that provides the complete capability, including terminal equipment functions, for communication between users according to standardised protocols and transmission capabilities established by agreement between operators.
