ETSI ETSI TR 102 300-6 V1.1.2 (2016-05)6 1 Scope The present document is written as a “Read-me-first“ manual or “Getting started with TETRA Air-Ground-Air“. It is not intended to be a guide to the TETRA Air-Ground-Air standard nor an authoritative inter
23、pretation of the standard. If any conflict is found between the present document and the corresponding sections in the TETRA standard then the standard takes precedence. The reader of the present document is assumed to have a working knowledge TETRA technology. The guidance provided in the present d
24、ocument is prepared with the experience of implementing an Air-Ground-Air to an existing national network. The aims of the present document are: to introduce and detail the different aspects of Air-to-Ground communication in a TETRA network; to show the reader that Air-Ground-Air is an integral part
25、 of a TETRA network when required; to provide the reader with sufficient knowledge to engage in qualified discussions with the equipment and service suppliers; to expose the reader to the specific language and technical terminology used in the present document; to enable the reader to understand the
26、 flexibility in system design, system network topography, system availability, various modes of operation and security features; to provide basic guidance on optimizing a TETRA network when including an Air-Ground-Air element. The present document provides guidance on the requirements for an Air-Gro
27、und-Air service and how best to implement an AGA service. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

34、 abbreviations 3.1 Definitions For the purposes of the present document, the following terms and definitions apply: path delay function: cell reselection initiated by path delay NOTE: The time taken for signal to perform a round-trip between the MS and Cell is known as the “Path Delay“. When this ti
35、me exceeds a preset value the SwMI informs the MS that maximum path delay is exceeded and causes the MS to initiate cell reselection. Preferred Location Area (PLA): set of cells MS prefers against other cells NOTE: A number of Location Area Codes may be programmed into the MS. The MS on receiving on
36、e or more of these LAs in the neighbour list of the cell it is affiliated to will “prefer“ to use the cell associated with one of those LAs. Mobility to and away from such cells is defined in ETSI EN 300 392-2, clause 18 i.2 and TETRA Interoperability Profile 16 i.4. PLAs may also be known as “Home
37、Location Areas“. RF carrier: distinct radio frequency on which radio channel may be active Subscriber Class (SC): subdivision of the subscriber population NOTE: There are 16 subscriber classes defined for use on TETRA networks. Those 16 classes are divided into 3 groups, Highly Preferred Subscriber
38、Class, Preferred Subscriber Class and (Basic) Subscriber Class. Mobility between the 3 groups of subscriber class is defined in ETSI EN 300 392-2 i.2 and TETRA Interoperability Profile 16 i.4.

43、e communications where most subscribers are operating terminal equipment at sea or at ground level. There are a number of users, however, whose communication needs require operation at thousands of feet above ground level. Air-Ground-Air (AGA) operation, also known as Air-To-Ground (ATG or A2G) is a
44、 TETRA radio service designed to provide communication between radio users operating from airborne assets and ground based operatives including radio users and dispatchers. The airborne assets typically will be comparatively small in number operating comparatively infrequently. However once they are
45、 operational their effectiveness is highly valued. Most TETRA radio networks are primarily designed as a cellular network providing a land-mobile radio service, so significant design changes have to be implemented to service the requirements for effective AGA use. The AGA service is provided by depl
46、oying an overlay network of Radio Cells or “Air Cells“ that provide the user with communications typically from 500 feet (150 m) upwards. ETSI ETSI TR 102 300-6 V1.1.2 (2016-05)9 4.2 Spectrum The spectrum for AGA use is reserved solely for AGA purposes. There are several reasons for this, including:
47、 Radio channels are a scarce resource. Fortunately they can be re-used at a distance. This is possible due to the path loss caused by distance, landscape and buildings. In land-mobile networks the re-use distance is typically 50 km due to the high path loss of landscape and buildings. Path Loss at a
48、ltitude is much less than at ground level. Transmitting at altitude on a land mobile network would result in interference on several land-mobile Base Stations that re-use the same radio channel. The EU-wide network plan, see annex A, if followed closely will minimize co-channel interference to accep
49、table levels. An internationally agreed frequency allocation is easier to implement to minimize interference between networks, refer to ECC/DEC/(06)05 i.1. A small number of widely spaced radio cells supplying service for AGA purposes. The cells will radiate at lower power than cells used in the ground network. 5 Technical Design 5.1 Concept of Overlay Network Due to the limited range of RF signals radio networks normally have a cellular structure where channels are re-used at a regular distance.
