Mobile Network Identity
(MNI)
The identity that is broadcast by all TETRA base stations
to uniquely identify the network.
Mobile Station (MS)
Mobile peripheral equipment. The following types are to
be distinguished: mobile phone, portable phone and
radio data terminal.
Network
A collection of subscriber terminals interconnected
through telecommunications devices.
Network Management
System (NMS)
The NMS is a remote management system able to
control a number of Switching and Control Nodes and to
have complete visibility of the whole system.
On/Off Hook Signalling
A signalling procedure which includes an alerting
process to the called user. An explicit response from the
called user that he has answered is waited [sic] before
the call can be set-up.
Peripheral Equipment
Equipment intended for communication via the network
or in direct mode, over the air interface. Line stations
with the functionality of peripheral equipment are likewise
included as well as DMO-gateways and DMO-repeaters.
Pre-emptive Priority Call
According to this service, several calls may be pre-
empted to satisfy the higher priority call. This means that
those calls are shut down, and the traffic channels are
allocated for other high-priority tasks.
Priority Call
This service allows the infrastructure to give priority
access to network resources to calls which have been
sent with priority status.
Quality of Service (QoS)
Refers to certain characteristics of a Network Connection
(NC) as observed between the NC endpoints which are
attributable solely to the Network Service (NS) provider.
Short Data Service
(SDS)
Service allowing a subscriber (MS or Dispatcher) to send
pre-defined and user defined short messages to another
subscriber or group of subscribers.
Short Subscriber
Identity (SSI)
The network specific portion of a TSI. An SSI is unique
within one TETRA sub-domain (one TETRA network).
There are four different types of SSI (see subclause
7.2.3):
a) Individual SSI (ISSI);
b) Group SSI (GSSI);
c) Alias SSI (ASSI);
d) Un-exchanged SSI (USSI).
Supplementary Service
A service which modifies or supplements a bearer
service or a teleservice. A supplementary service cannot
be offered to a customer as a stand-alone service. It
should be offered in combination with a bearer service or
a teleservice.
Talking Party
Identification (TPI)
TPI enables all the parties involved in a call to be made
aware of the identity of the talking party.
