Introduction The Terms of Reference for TC TETRA approved at E

17、TSI 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 functionality as required by traditional Professional Mobile Radio (PMR) user organizations such as

18、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 required by the market with the provision of new services, facilities and functionality made possible b

19、y 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 performance, quality of service, security and other relevant parameters. ETSI ETSI TR 102 021-10 V1

20、.1.1 (2010-12)5 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 of TETRA users. Technical Objective TETRA is one of a number of digital wireless communication techn

21、ologies 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 document provides the User Requirement Specifications for the TETRA Local Mode Broadband. Background

22、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 changed this by deve

23、lopment 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 using real-time multimedia applications will be feasible in TETRA. This is however only a development which improves fixed trun

24、king network, based on an architecture which assumes a fixed infrastructure with connections to a central intelligent switch, the SwMI. There are also needs to cover ad-hoc incident areas with IP-based networks which should support all current services of TETRA (voice, SDS and IP) and allow applicat

25、ions like sensor data and real-time multimedia applications like video images to be used. TC TETRA organised a workshop at the TETRA World Congress 2007 to discuss the candidate TETRA enhancement areas for TETRA Release 2 evolution. The workshop enhancement area are detailed in annex A. Regarding to

26、 Local Mode Broadband, 2 enhancement areas were identified and specified as: Local Mode Broadband Even though the TETRA standard has been enhanced for “wide-band“ applications with the introduction of TEDS, some suggestions have been made to further increase data throughput to match that offered by

27、broadband data services. For example, some suggestions have been to provide access to broadband services in certain “hot zones“ within a TETRA Voice and Data network coverage area. It was also suggested that “hot zone“ coverage should dynamically increased and/or decreased as required for communicat

28、ion purposes. Networking capability for Local Mode Broadband area to Local Mode Broadband area To further enhance the capability of broadband services in certain “hot zones“ as suggested above, there have also been suggestions to increase “hot zone“ coverage by interconnecting different “hot zones“

29、together via the TETRA Voice and Data network. ETSI ETSI TR 102 021-10 V1.1.1 (2010-12)61 Scope The present document provides the User Requirement Specifications for the TETRA Local Mode Broadband. To improve TETRA on-site communication capabilities, the LMB aims at allowing the intervention teams t

30、o dynamically deploy an ad-hoc wireless network within the incident area, supporting voice, video and data communication (e.g. sensor-based data such as oxygen, gas, temperature). The ad-hoc wireless network should be made robust and redundant, securely supporting intervention teams of different dis

31、ciplines within the same incident area. This ad-hoc wireless network should be capable of being securely connected, extended and integrated into the into a larger outdoor TETRA network. NOTE: Further study may be required before a standardization effort is initiated. 2 References References are eith

38、Network 4 Local Mode Broadband (LMB) 4.1 Local The coverage area of LMB is (in the start-up) limited to “on-site“, meaning the “incident area“. LMB is an ad-hoc wireless network that can be deployed anywhere very quickly by “intervention“ teams. This means that the equipment should be small and “sim

39、ple“, not needing people with technical knowledge. For large scale disasters, the communication in general complies with the “hourglass model“. With the “hourglass model“ the following is meant: At the incident area, a lot of information is gathered (video footage from different cameras, the differe

40、nt conversations that are recorded, sensor data, etc.) In general, it is unnecessary and impossible to transmit all this information to the crisis centre. The crisis centre has no use for individual sensor data, nor for every individual conversation that takes place in the incident area. On the othe

41、r hand, if the link between the local command and the crisis centre is a narrowband or even wideband link the bandwidth provided by this link is insufficient to transmit all the data. Similarly, the crisis centre collects a lot of information from many different sources. It is not feasible and even

42、not wanted to send all this information to the local command. Hence the “hourglass model“: a lot of information is available at both sides, but only a narrow “pipe“ is available to transfer information between both sides. Therefore, only the most relevant information is transmitted between the local

43、 command and the crisis centre. This includes e.g. the voice communication between the local command and the crisis centre, and aggregated information containing the number of people injured, aggregated sensor data, information about how many hospital beds are available, whether or not to evacuate a

44、 certain region. This pipe can also be used to exchange “delta“ information on information already available (e.g. previously synchronized before departure of the vehicles). When enough bandwidth is available, more data (e.g. video footage from a helicopter that gives a good overview of the incident

45、 area) can be transferred between the local command and the crisis centre. This data, however, has lower priority than the voice communication and the aggregated data mentioned above. When bandwidth becomes limited, these streams will be dropped. ETSI ETSI TR 102 021-10 V1.1.1 (2010-12)84.2 Broadban

46、d The “data-throughput“ of the LMB is expected to at least support the TETRA 1 (voice, SDS, IP) and TETRA 2 (wide-band applications introduced with TEDS) services and throughputs if the used frequencies dont allow high bandwidth (“channels“). The “data-throughput“ of the LMB is expected to support r

47、eal broadband services and throughputs if the used frequencies allow high bandwidth (“channels“). This probably means a flexible solution with 2 tracks: a local mode “wideband“ (LMW) solution which supports the current TETRA 2 services and throughputs (limited to “wideband“); a local mode “broadband

48、“ (LMB) solution which supports new broadband services and throughputs. 5 Networking capability for Local Mode Broadband area to Local Mode Broadband area It is expected that LMB areas (equipment/network) with overlapping coverage can be connected together to form “one“ LMB area (network). Within th

49、is new LMB area all services of both initial LMB areas become available over the whole new LMB area. It is expected that this can happen automatically based on preconfigured settings in the LMB equipment. It is expected that this can happen also for networks of independent organisations: E.g. a police LMB network and a fire service LMB network “see“ each other and automatically, transparently, etc. (without “intervention“ team involvement) transform to a single LMB network area supporting all previously supported services over the whole LMB are
