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.
is a type of telecommunication service that provides the capability of transmission of signals between access points.
a logical association between several users (this could be connection oriented or connection less).
is a communication channel between two or more end-points (e.g. terminal, server etc.).
the mobile termination is the component of the user equipment which supports functions specific to management of the radio interface (Um).
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.
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 are made up of different service capability features.
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.
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.
