Foreword This Technical Specification (TS) has been produced by ETSI Project Terrestrial Trunked Radio (TETRA). The present document is part 10 of a multi-part deliv
22、rable covering the Technical requirements for Direct Mode Operation (DMO), as identified below: Part 1: Part 2: Part 3: Part 4: Part 5: Part 6: Part 7: Part 8: Part 9: Part 10: General network design; Radio aspects; Mobile Station to Mobile Station (MS-MS) Air Interface (AI) protocol; Type 1 repeate
23、r air interface; Gateway air interface; Security; Type 2 repeater air interface; Protocol Implementation Conformance Statement (PICS) proforma specification; Service and Description Language (SDL) model; Managed Direct Mode Operation (M-DMO). ETSI 6 ETSI TS 1 O0 396-1 O V1.l.l (2000-1 2) 1 Scope TS
24、100 396 defines the Terrestrial Trunked Radio (TETRA) Direct Mode Operation (DMO). It specifies the basic air interface, the inter-working between Direct Mode (DM) groups via repeaters, and inter-working with the TETRA Voice plus Data (V+D) system via gateways. It also specifies the security aspects
25、 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
26、 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 b
27、e 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 fro
28、m 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 ftom 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
29、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.
30、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
31、 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
32、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 ETSEN 300 396. The present document does not define the process for deciding which frequencies are allocated to M-DMO use. 2 References The following documents contain

39、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. It permits M-DM-MSs which receive this message to know that the M-DM-AUTH is within range. It indic
40、ates 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: there are two types of call, individual call or group call. An individual call is a complete sequence of related call transactions between two MSs. There are always t
41、wo participants in an individual call. 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. Participants may join (late entry) and leave an ongoing call call transaction: all of the f
42、unctions associated with a complete unidirectional transmission of information during a call. 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 tra
43、nsmitting 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. D
44、M 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). The grouping may not always be fixed, but in DMO when operating in fi-equency efficient mode as an example, there are two DM channels, identified by the letters A and B. Di
45、rect 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. DM operation is performed without intervention of any base station. direct mode pre
46、sence 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. 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. ETSI 8 ETSI TS 1 O0 396-1 O V1.l.l (
47、2000-1 2) Direct Mode Mobile Station (DM-MS): physical grouping that contains all of the mobile equipment that is used to obtain TETRA DM services. 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
48、 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. Only one mode can be s
49、elected 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. 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. The gateway
