Introduction The Terms of Reference for TC TETRA approved at ETSI Board meeting #69, November 2008 are to produce ETSI deliverables (and maintenance thereafter) in accordance with the following requirements: The provision of user driven services, facilities and
28、functionality as required by traditional Professional Mobile Radio (PMR) user organizations such as the Emergency Services, Government, Military, Transportation, Utility and Industrial organizations as well as Public Access Mobile Radio (PAMR) Operators. The evolution and enhancement of TETRA as req
29、uired by the market with the provision of new services, facilities and functionality made possible by new technology innovations and standards. Further enhancements of the TETRA standard in order to provide increased benefits and optimization in terms of spectrum efficiency, network capacity, system
30、 performance, quality of service, security and other relevant parameters. ETSI ETSI TR 102 021-9 V1.2.1 (2010-12)7 The backward compatibility and integration of the new services, facilities and functionality with existing TETRA standards in order to future-proof the existing and future investments o
31、f TETRA users. Technical Objective TETRA is one of a number of digital wireless communication technologies standardized by ETSI. ETSI TC TETRA produces standards and/or adapts existing standards for efficient digital PMR and PAMR voice and data services, including broadband evolution. The present do
32、cument provides the User Requirement Specifications for the TETRA Peripheral Equipment Interface enhancements. The TETRA Release 2 standard, incorporating the high-speed capability (TEDS) has just been published. This high-speed data capability increases the maximum data rate of the TETRA systems fr
33、om 28,8 kbit/s to over 500 kbit/s, which has the capability to radically changing the range of data applications available to TETRA users. The current TETRA PEI standard, EN 300 392-5 i.14 is a narrow band interface with limited application handling capability for the Release 2 type TETRA networks.
34、Hence, an enhanced PEI with a concurrent multimedia capability is essential to enable access to the system from a range of data terminals (such as laptops, etc.). The URS is required by WG3 and WG4 of TC TETRA to guide the enhancement of the current TETRA PEI standard. Background The PEI standard EN
35、 300 392-5 i.14, defines a point-to-point configuration between a TE2 and a MT2 using a sub-set of ITU-T Recommendations V.24 i.15 and V.28 i.16. The V.24 i.15 standard provides list of definitions for interchange circuits between Data Terminal Equipment (DTE) and Data Circuit-Terminating Equipment
36、(DCE), first agreed in 1964 which is equivalent to a subset of TIA/EIA-232 i.17. Beside large voltage swings, limitations in noise immunity and low reliability of the flow control mechanisms that EN 300 392-5 i.14 introduces, the achievable data rate is also a major bottleneck in wide-band capabilit
37、y of the TETRA release 2. In order to propose appropriate physical links, an initial study has already been carried out by HW communications Ltd and submitted to ETSI TC TETRA WG4 as a response to the ETSIs call for STF 314 on TETRA Release 2 PEI i.14. The present document, recommends wired and wire
38、less physical link candidates that should be used between a Terminal Equipment 2 (TE2) and a Mobile Termination 2 (MT2) at the TETRA reference point RT i.14. The PEI standard TS 100 392-5 (V2.1.1) i.24 added high speed support including USB and wireless interfaces such as Bluetooth. Need for a Physi
39、cal Link Update Before the initiation of TETRA Release 2, limited attention has been paid to the provision of IP-based wideband multimedia services in Private Mobile Radio (PMR) wireless networks, such as those used by public safety organizations in TETRA release 1. However, TETRA Release 2 has chan
40、ged this by development of TEDS, which intends to broaden the spectrum of multimedia services offered to TETRA users. As TEDS offers data rates comparable to that of 2,5G/3G networks, then the using real-time multimedia applications will be feasible in TETRA. For example, in table 1, the average req
41、uired throughput for real-time video is presented. The video resolution and frame sizes are derived based on ITU-T Recommendation H.264 i.1. It is clear that for TETRA2, using outdated physical link technologies such as TIA/EIA-232 i.17 which supports maximum data rate of 20 kbit/s is no longer a fe
42、asible option. Table 1: Average throughput for real-time video transmission Multimedia service Average throughput (kbit/s) Real-time video (Resolution/frame) 128 96 / 30,9 176 144 / 15,0 64 176 144 / 30,3 320 240 / 10,0 192 A list of applications with minimum required data rates for transmission is
43、provided in annex A. ETSI ETSI TR 102 021-9 V1.2.1 (2010-12)81 Scope The present document provides the User Requirement Specifications (URS) for the enhancements of the TETRA Peripheral Equipment Interface. The existing TETRA PEI standard has been available since 1998. The TETRA Release 2 standard,
44、incorporating the high-speed data capability (TEDS) has been published. This HSD capability increases the maximum data rate of the TETRA systems from 28,8 kbit/s to over 500 kbit/s, radically changing the range of data applications available to TETRA users. The TETRA users could, from now on, use a
45、range of multimedia applications (with video as a medium) via TEDS channels. One bottleneck to making full use of this new capability is the restrictions imposed by interfacing TETRA Release 2 systems via mobile stations only. Hence, a standard HSD PEI with a concurrent multimedia capability is esse
46、ntial to enable access to the system from a range of data terminals (such as laptops, etc.). Peripheral Equipment Interface enhancements translated into terms of: PEI physical layer aspects. Multimedia capability. QoS negotiation. The present document is applicable to the specification of TETRA Rele
