1 Scope The multi-part deliverable ETS/EN 300 396 defines the Terrestrial Trunked Radio (TETRA) Direct Mode Operation (DMO). It specifies the basic air interface, the interworking between 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 TETRA 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 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 frequency shall comply with the transmit restrictions defined 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 from 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. An 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 mobile 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 differences 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 300 396. The present document does not define the process for deciding which frequencies are allocated to M-DMO use. SIST EN 300 396-10 V1.1.2:2003

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 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. SIST EN 300 396-10 V1.1.2:2003

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, 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 the 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 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 operation 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-GATE, 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 transmitting traffic or control data, or is reserving the channel by means of channel reservation signalling; - slave: if the DM-MS is receiving traffic and/or 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 operation NOTE: The MS is capable of periodically monitoring the V+D control channel while in a DM call, a DM RF carrier while in a V+D call and, when idle, it periodically monitors both the DM RF carrier and the V+D control channel. Direct Mode GATEway (DM-GATE): device which provides gateway connectivity between DM-MS(s) and the TETRA V+D network NOTE: The gateway provides the interface between TETRA DMO and TETRA V+D mode. Direct Mode REPeater (DM-REP): device that operates in TETRA DMO and provides a repeater function to enable two or more DM-MSs to extend their coverage range NOTE: It may be either a type 1 DM-REP, capable of supporting only a single call on the air interface, or a type 2 DM-REP, capable of supporting two calls on the air interface. A type 1 DM-REP may operate on either a single RF carrier (type 1A DM-REP) or a pair of duplex-spaced RF carriers (type 1B DM-REP). A type 2 DM-REP operates on a pair of duplex-spaced RF carriers. In the case of a type 1B or type 2 DM-REP, one of the RF carriers is used as the "uplink" from DM-MSs to the DM-REP and the other is used as the "downlink" from the DM-REP to DM-MSs.

Direct Mode REPeater/GATEway (DM-REP/GATE): device that combines the functions of a Direct Mode repeater and a Direct Mode gateway in a single implementation and is capable of providing both functions simultaneously (so that, during a call transaction initiated by a DM-MS, the DM-REP/GATE provides gateway connectivity to the TETRA V+D network and also provides a repeater function on the DM channel) NOTE: The repeater part of the combined implementation may be either a type 1A repeater, operating on a single DM RF carrier, or a type 1B repeater, operating on a pair of duplex-spaced DM RF carriers. frequency efficient mode: mode of operation where two independent DM communications are supported on a single RF carrier (or pair of duplex-spaced RF carriers for operation with a type 2 DM-REP) NOTE: In frequency efficient mode the two DM channels are identified as channel A and channel B. gateway: generic term used to describe either a pure DM-GATE or a combined implementation with a repeater (DM-REP/GATE) Managed Direct Mode Operation (M-DMO): method of operation in which a direct mode terminal is only permitted to transmit when it has received a signal authorizing it to do so Managed Direct Mode AUTHorizing unit (M-DM-AUTH): device that transmits an authorization presence signal on a DM RF carrier NOTE: An 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 (in which case it is referred to as an M-DM-REP, M-DM-GATE or M-DM-REP/GATE respectively). M-DMO management station: station that is accessed via the V+D network and is authorized to allocate frequencies for M-DMO Managed Direct Mode Mobile Station (M-DM-MS): DM-MS that is using managed direct mode operation NOTE: An M-DM-MS is not permitted to transmit on the DM RF carrier unless it has received a signal containing authorization and the authorized time has not expired. The authorization may have been received from an M-DM-AUTH transmitting on the DM RF carrier. Alternatively the authorization may have been received from the V+D SwMI or an M-DMO management station (in which case the M-DM-MS is referred to as a V+D authorized M-DM-MS). normal mode: mode of operation where only one DM communication is supported on an RF carrier (or pair of duplex-spaced RF carriers for operation with a type 1B DM-REP or type 1B DM-REP/GATE) surveillance: process of determining the current state of the DM RF carrier when in idle mode trunked voice and data network: network which uses the TETRA V+D operation V+D authorized M-DM-MS: type of M-DM-MS that receives its authorization to transmit on the DM RF carrier directly from the V+D SwMI or from an M-DMO management station via the V+D network V+D operation: mode of operation where MSs may communicate via the TETRA V+D air interface which is controlled by the TETRA Switching and Management Infrastructure (SwMI) 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: DM Direct Mode DMO Direct Mode Operation DM-MS Direct Mode Mobile Station DU-MS DUal mode (V+D/Direct Mode) switchable Mobile Station DW-MS Dual Watch Mobile Station DM-REP Direct Mode REPeater DM-GATE Direct Mode GATEway DM-REP/GATE Direct Mode REPeater/GATEway DMCC Direct Mode Call Control entity DSB Direct Mode Synchronization Burst SIST EN 300 396-10 V1.1.2:2003
