Terrestrial Trunked Radio (TETRA)

Die Annotation des Normtextes ČSN ETSI EN 300392-1-V1.6.1 (875042):

V1.6.1

The present document defines addressing for Terrestrial Trunked Radio system (TETRA) supporting Voice plus Data (V+D). It also gives background information of the air interface, the interworking between TETRA systems and to other systems via gateways, the terminal equipment interface on the Mobile Station (MS), the security aspects in TETRA networks, the management services offered to the operator, the performance objectives, and the supplementary services that come in addition to the basic and tele-services used as a basis for TETRA standardization.

The present document defines and specifies the TETRA addressing and identities and their organization in groups corresponding to the different functions.

It establishes the background of the TETRA general network design for standardization purposes:

• - it gives information about the circuit mode and packet mode reference points for the MS and switching and management infrastructure;
• - it gives information about a model of the air interface protocol stack, different functions of layers and sublayers;
• - it gives information about the functions provided by the circuit mode teleservices used for speech and basic services used for data transfer;
• - it gives information about the functions related to the management of the users´ mobility across networks and inside a network including roaming and migration;
• - it gives information about the functions related to the transport of short data messages as a service specific to TETRA;
• - it gives information about the functions related to the support of packet data service in a way specific to TETRA;
• - it gives information about the supplementary services that mainly extend the capabilities of the circuit mode basic and teleservices;
• - it gives information about the various possibilities of individual circuit mode call scenarios and provides guidance on priority concepts for packet data and circuit mode services and on the service quality.
