4 | GMR (GEO-Mobile Radio) is a communication system specified at ETSI (European Telecommunications Standardization Institute). |
||
5 | |||
6 | GMR is based heavily by GSM, which was also originally specified by ETSI. |
||
7 | |||
8 | As there are so many areas of overlap and re-use between GSM and GMR, the GMR specifications in fact only |
||
9 | specify the differences to the GSM system. Many GSM documents are referenced completely, others on a paragraph/chapter |
||
10 | base. |
||
11 | |||
12 | == Revisions == |
||
13 | |||
14 | GMR comes in three revisions (so far) |
||
15 | * GMR Release 1 (GMR-1) -- Voice telephony and SMS only |
||
16 | * GMR Release 2 (GmPRS) -- Packet Data services similar to GPRS |
||
17 | * GMR Release 3 (GMR 3G) |
||
18 | |||
19 | == Specification Numbering Scheme == |
||
20 | |||
21 | == Differences to GSM == |
||
22 | |||
23 | * the GBCH for broadcasting GPS ephemeris data on the CCCH downlink ARFCN was introduced |
||
24 | * the RACH request (Channel Request) includes GPS coordinates and the called number (in plaintext!) |
||
25 | * there is a new A5/2 cipher variant, specific to GMR-1 |
||
26 | * pi/4 QPSK modulation instead of GMSK |
||
27 | * different bursts and TDMA multiplex / multi-frame |
||
28 | * different speech codecs (lower bitrate), AMBE |
||
29 | * new lower-bitrate TCH and SDCCH types (TCH3, TCH6, SDDCH3, SDCCH6) |
||
30 | * LAPDm has a k=16 window size for outstanding unacknowledged segments (due to satellite delays) |
||
31 | |||
32 | == Dictionary == |
||
33 | |||
34 | GMR TS 01.201 gives a good overview about the terminology differences between GSM and GMR, specifically |
||
35 | * BSC -> GSC |
||
36 | * BSS -> GSS |
||
37 | * BTS -> GTS |
||
38 | * Cell -> Spot beam |
||
39 | * GSM -> GMR |
||
40 | * ME -> MES-ME |
||
41 | * MS -> MES-MS |
||
42 | * MSC -> GSS-MSC |
||
