3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in EN 300 392-2 [2] and EN 300 396-3 [5]
and the following apply:
assign: addition of group definition
assigned DMO group: DMO group with a valid parameter set, which has been assigned by a network operator
deassign: permanent removal of group definition
default DMO group: preferred DMO group which is selected when a mobile station switches from V+D to DMO
NOTE: A default DMO group is both, an assigned and a preferred DMO group.
DMO channel: Radio Frequency (RF) carrier for DMO usage
DMO group: DMO group defined by the parameter set: a TETRA group address, a mnemonic group name, a DMO
channel, and a mnemonic DMO channel name
NOTE: DMO groups contain some additional parameters to the above list that is seen on the user's point of view.
management server: entity that manages DMO equipment
management source: originator of DMO management commands
preferred DMO group: assigned DMO group which has been assigned to a specific organisation for preferred usage
NOTE: There can be multiple preferred DMO groups defined at the same time.
selected DMO group: DMO group that MS user has selected
NOTE: A selected DMO group is a default, a preferred or an assigned DMO group.
Switching And Management Infrastructure (SwMI): all of the TETRA equipment for a Voice plus Data (V+D)
network except for subscriber terminals
TETRA domain: all entities that are addressed using TETRA defined addresses
NOTE: This definition may cover entities that are not controlled by TETRA security features.

4 Direct mode operation over the air management
protocol
4.1 General
The Direct mode operation Over The Air Management (DOTAM) is a TETRA air interface management protocol that
could utilize various transport mechanisms.
The present document defines "control messages" to set and modify MS behaviour in DMO.
The management protocol can be used in various system configurations including:
• SwMI to MS communication.
• Management server to MS communication.
• MS to management server communication.
ETSI

---------------------- Page: 8 ----------------------
9 ETSI TS 100 392-18-3 V1.1.1 (2009-11)
NOTE 1: Although DOTAM protocol can support direct MS to individual MS communication; the use of it may be
limited to specific situations and is outside the scope of the present document.
NOTE 2: DOTAM does not preclude the usage of pre-configured group and/or frequency settings. It is outside the
scope of the present document how DOTAM and pre-configured group and/or frequency settings may
interact.
The DOTAM protocol may be a member of various other MS over the air management services such as:
• DGNA - V+D group management;
• Phonebook management - ISSI & MS-ISDN management;
• Remote programming of Status message mnemonics;
• Remote programming of technical parameters (timers, etc.);
• Remote software upgrade;
• OTAR/OTAK.
The first on the list is covered by SS-DGNA. The second is in relation to the first one and to the present document, but
is outside the scope of the present document.
4.2 DOTAM protocol system architecture
The DOTAM protocol is used between various entities of the TETRA network. Physical entities identified for the
purpose of the present document are:
• Mobile Station (MS).
• Management server.
• SwMI.
• Management source.
The management server details are outside the scope of the present document.
The management information exchange contains scenarios:
• Management server to managed MS in the TETRA V+D domain.
• Management source equipment to Management server.
• Management source MS to managed MS in DMO without any action in any other entities.
For the purposes of the present document, the TETRA domain consists of entities that are addressable using TETRA
addressing and understand the binary format of the DOTAM protocol.
For the purposes of the present document protocol Functional Entities (FE) are used in some clauses instead of physical
entities:
FE1: Managed entity.
FE2: Management server entity.
FE3: Management source entity.
The following relationships exit between these FEs:
ra: Relationship between management server entity and managed entity.
rb: Relationship between management source entity and management server entity.
rc: Relationship between management source entity and managed entity.
