ETSI ETSI TR 102 021-4 V1.4.1 (2011-08)5c) Further enhancements of the TETRA standard in order to provide increased benefits and optimization in terms of spectrum efficiency, network capacity, sy
24、stem performance, quality of service, security and other relevant parameters. d) 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
25、 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 document provides the User Requireme
26、nt Specifications for the TETRA air interface enhancements. The URS is required by TC TETRA to guide the enhancement of the current TETRA standard, mainly the evolution of the HSD standard part towards broadband.

27、Requirement Specifications (URS) for the TETRA air interface enhancements translated into terms of: network performance aspects; terminal performance aspects; location information aspects. The present document is applicable to the specification of TETRA Release 2.1 equipment. The user requirements c
28、ontained in the present document are described in non-technical terms and are based on discussions in TC TETRA WG1 and on an analysis of the results for air interface enhancements from the 2001 TETRA Release 2 Market Questionnaire and the 2007 Future of TETRA workshop i.1. 2 References References ar

41、pectrum efficiency, network capacity, system performance, quality of service, size and cost of terminals, battery life, and other relevant parameters. Other possible air interface enhancements are providing increased coverage range and low cost deployments for applications such as airborne public sa
42、fety, maritime, rural telephony and “linear utilities“ (e.g. pipelines). Provisioning of location information is another service that could be provided by enhancements of the TETRA air interface standard. 4.2 Network performance aspects 4.2.1 Overview of network performance aspects The network perfo
43、rmance aspects to be enhanced or supported in TETRA Release 2 are listed below: improved spectrum efficiency; enhanced network capacity; improved end-to-end time delay performance; Base Station site RF coverage beyond the current 58 km radius limitation of TETRA Release 1; improved RF performance; l
44、ocation positioning accuracy better than base station site location (Cell ID); improved cell hand-over decision and management; SDS improvements including concatenation; user aliases. Most of these elements are difficult to quantify by users. The user requirements can generally be expressed as the m
45、ore improvement the better. Some of these elements require substantial standardization effort. These requirements will compete for standardization resources and, as such, compromise each other. In the 2001 questionnaire responses, users indicated how they judged the relative importance of these elem
46、ents. This gives an indication which items deserve most standardization effort. Some enhancements may be satisfied by implementation rather than standardization. The different aspects are listed in clauses 4.2.2 to 4.2.7 in descending order of TETRA user market importance as judged by the 2001 quest
47、ionnaire panel, further clauses under clause 4.2 are in no specific order of importance. 4.2.2 Enhanced network capacity Enhanced network capacity is the most important requirement for the general TETRA market and also in all market segments. Most of the respondents (users/operators) in 2001 were st
48、ill starting up their TETRA networks. These networks were not under normal or full load and most respondents could only estimate the capacity load of their systems. The majority of those users had traditional analogue private open channel PMR systems. Therefore, it was very difficult (depending on t
49、he individual user/organization behaviour) to estimate how effective the statistical multiplexing of TETRA trunking will be. It is likely that the capacity gain of trunking has been underestimated. As a result of underestimating the trunking effect, enhancing network capacity could be too high on the list of the general user requirements.
