Foreword This European Standard (Telecommunication
22、s series) has been produced by ETSI Project Terrestrial Trunked Radio (TETRA).

It specifies the basic air interface, the interworking betw
26、een Direct Mode (DM) groups via repeaters, and interworking with the TETRA Voice plus Data (V+D) system via gateways. It also specifies the security aspects in TETRA DMO, and the intrinsic services that are supported in addition to the basic bearer and teleservices. The present document defines TETR
27、A Managed Direct Mode Operation (M-DMO). M-DMO provides a means to restrict the use of Direct Mode Operation (DMO) by requiring prior authorization before a Direct Mode Mobile Station (DM-MS) is permitted to transmit on a radio frequency. This modifies the operation of DM-MSs from that specified in
28、ETS 300 396-3 3, EN 300 396-4 4, ETS 300 396-5 5 and EN 300 396-7 7. M-DMO provides a control mechanism by which radio frequencies (M-DMO frequencies) may be given for DMO use for a period of time; those frequencies are considered to be managed frequencies. All M-DMO devices operating on a managed f
29、requency shall comply with the transmit restrictions defiied in the present document. An M-DMO DM-MS (M-DM-MS) may receive the authorization to transmit from a broadcast signal sent on the M-DMO frequency. Or, alternatively, it may obtain the authorization directly on the V+D side from the SwMI or f
30、rom an M-DMO management station. The authorizing unit which sends the broadcast signal on the M-DMO frequency is referred to as an M-DM-AUTH. It obtains the authorization to operate as an M-DM-AUTH from the V+D SwMI or from a management station that is authorized to allocate frequencies for M-DMO. A
31、n M-DM-AUTH may be a stand-alone unit (performing only the authorization function), or it may perform also the function of a DM-REP, DM-GATE or DM-REP/GATE. The content of the present document is as follows: - - Clause 4: provides an overview of M-DMO; Clause 5: describes the procedures for M-DMO mo
32、bile stations; - - - Clause 6: describes the procedures for M-DM-AUTHs; Clause 7: describes the operation of M-DMO frequencies; Clause 8: describes the usage of the authorization presence signal; - - Annex A: lists the timers and constants specific to M-DMO; Annexes B through F: describe the differe
33、nces from ETS 300 396-3 3, EN 300 396-4 4, ETS 300 396-5 5 and EN 300 396-7 7 arising from M-DMO. The present document assumes familiarity with operation of TETRA in a network environment as described in EN 300 392, and with operation of TETRA in Direct Mode as described in other parts of ETS/EN 300
34、 396. The present document does not define the process for deciding which frequencies are allocated to M-DMO use.

40、lowing terms and definitions apply: authorization datum point: geographical point in space from which M-DMO is allowed authorization presence signal: message that is transmitted by an M-DM-AUTH on an M-DMO RF carrier NOTE: It permits M-DM-MSs which receive this message to know that the M-DM-AUTH is
41、within range. It indicates which M-DM-MSs are authorized to transmit on the RF carrier, and the validity time for which those M-DM-MSs are authorized. call: individual call or group call NOTE 1: An individual call is a complete sequence of related call transactions between two MSs. There are always
42、two participants in an individual call. NOTE 2: A group call is a complete sequence of related call transactions involving two or more MSs. The number of participants in a group call is not fixed, but is at least two. NOTE 3: Participants may Join (late entry) and leave an ongoing call. ETSI 8 ETSI
43、EN 300 396-1 O VI .I .2 (2002-08) call transaction: all of the functions associated with a complete unidirectional transmission of information during a call NOTE: A call is made up of one or more call transactions. In a simplex call these call transactions are sequential. changeover: within a call,
44、the process of effecting a transfer of the master role (and hence transmitting MS) at the end of one call transaction so that another can commence Direct Mode Call Control (DMCC): layer 3 entity responsible for setting up and maintaining a call in DMO DM channel: specific grouping of timeslots in th
45、e DM multiplex structure related to a particular DM RF carrier i.e. DM frequency (or to a pair of duplex-spaced RF carriers for operation with a type 1B or type 2 DM-REP or a type 1B DM-REP/GATE) NOTE: The grouping may not always be fixed, but in DMO when operating in frequency efficient mode as an
46、example, there are two DM channels, identified by the letters A and B. Direct Mode Operation (DMO): mode of simplex operation where mobile subscriber radio units may communicate using radio frequencies which may be monitored by, but which are outside the control of, the TETRA V+D network NOTE: DM op
47、eration is performed without intervention of any base station. direct mode presence signal: message that is transmitted by a DM-REP, DM-GATE, DM-REP/GATE or M-DM-AUTH in order to indicate its presence on a DM RF carrier NOTE: It permits DM-MSs which receive this message to know that the DM-REP, DM-G
48、ATE, DM-REP/GATE or M-DM-AUTH is within range. Direct Mode Mobile Station (DM-MS): physical grouping that contains all of the mobile equipment that is used to obtain TETRA DM services NOTE: A DM-MS may have one of three roles: - master: if the DM-MS is either active in a call transaction transmittin
49、g traffic or control data, or is reserving the channel by means of channel reservation signalling; slave: if the DM-MS is receiving traffic andor signalling in a call; or idle: if the DM-MS is not in a call. - - Dual Mode switchable Mobile Station (DU-MS): MS that is capable of both TETRA DMO and TETRA V+D operation NOTE: Only one mode can be selected at any given time and the MS is not capable of monitoring a DM RF carrier while in V+D mode or a V+D channel while in DMO. Dual Watch Mobile Station (DW-MS): MS that is capable of both TETRA DMO and TETRA V+D oper
