The information pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found in

42、ETSI SR O00 3 14: “Intellectual Propero Rights (IPRs); Essential, or potentially Essential, IPRs notifed to ETSI in respect of ETSI standards“, which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web server (http:/www.etsi.ordipr). Pursuant to the ETSI IPR Policy,

43、no investigation, including IPR searches, has been carried out by ETSI. No guarantee can be given as to the existence of other IPRs not referenced in ETSI SR O00 314 (or the updates on the ETSI Web server) which are, or may be, or may become, essential to the present document. Foreword This Technica

44、l Specification (TS) has been produced by ETSI Project Terrestrial Trunked Radio (TETRA). The present document is part 7 of a multi-part deliverable covering the Technical requirements for Direct Mode Operation (DMO), as identified below: Part 1: “General network design“; Part 2: “Radio aspects“; Pa

45、rt 3: Part 4: Part 5: “Gateway air interface“; “Mobile Station to Mobile Station (MS-MS) Air Interface (AI) protocol“; “Type 1 repeater air interface“; Part 6: “Security“; Part 7: Part 8: “Type 2 repeater air interface“; “Protocol Implementation Conformance Statement (PICS) proforma specification“.

46、ETSI 8 ETSI TS 1 O0 396-7 V1.2.1 (2000-1 O) 1 Scope The present document 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

47、(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. This part applies to the TETRA Direct Mode Repeater (DM-REP) air interface and contains the specifications, where applicable

48、, of the physical, data link and network layers according to the IS0 model. The specifications contained herein apply to a DM-REP as a stand-alone unit supporting two calls on the air interface (type 2 DM-REP). They also cover the operation of a Direct Mode Mobile Station (DM-MS) with a type 2 DM-RE

49、P. NOTE 1: The specifications for a Direct Mode RepeatedGateway (DM-REP/GATE) combined implementation are provided in ETS 300 396-5 5, together with the specifications for a Direct Mode Gateway (DM-GATE). NOTE 2: The specifications for a DM-REP as a stand-alone unit supporting a single call on the air interface (type 1 DM-REP) are provided in EN 300 396-4 41. The protocol for a DM-MS operating with a type 2 DM-REP is specified in clauses 5 through 8, 10 and 11. Much of this protocol is defined in the form of a “delta document“ relative to the specifications provided in ETS 300 396
