Numbering scheme for TSs and TRs


Spec numbering scheme• Find the structure in 3GPP TR 21.900• Also on the web

http://www.3gpp.org/specification-numbering

At first sight, the numbering scheme for TSs and TRs may appear chaotic. But … it is organized chaos.

Spec numbers are not allocated on a per-TSG basis or on a per-WG basis, but on a functional basis.

Of course, particular WGs are responsible for particular functional areas of the system, so it is possible to have a reasonable guess at the group to whom a given Spec belongs on the basis of its number.


To understand the numbering scheme, it is necessary to go back in history a while …

GSM, Phase 1 to Phase 2+ Release 98

01.-series System requirements, rules, vocabulary, …

02.-series Stage 1 (service requirements)

03.-series Stage 2 (abstract architecture)

04.-series Stage 3 (protocols, mobile – network)

05.-series Radio physical layer, data link layer, radio resource protocols

06.-series CODECs

07.-series Data communication

08.-series Stage 3 Base station to mobile switching centre protocols

09.-series Stage 3 Intra-core-network layer 3 protocols

10.-series Work plan management (internal progress tracking reports)

11.-series SIM, terminal test specs

12.-series OA&M

13.-series European regulatory test specs


When 3GPP was established, the intention was to re-use as much of the GSM legacy as possible.

Especially in some series, there was almost total

commonality.


In some series, almost all available numbers had been exhausted.

So in the 3GPP numbering scheme, the range was increased from two digits after the dot to three:

02.xx → 22.xxx

So, for example, an old GSM R98 spec

02.16 “International Mobile Station Equipment Identities (IMEI)”

became, in R99, the common GSM and UMTS


and 02.16 does not exist in R99 and beyond.



became, in R99, the common GSM and UMTS


and 02.16 does not exist in R99 and beyond.

On the other hand

03.71 “LCS stage 3”

divided, in R99, into separate GSM and UMTS specs

03.71 “LCS stage 3”

and

23.171 “UMTS LCS stage 3”

and both exist in R99.


A brief digression onto GSM spec version numbering• Early drafts of specs are version 0.x.x• More stable drafts are version 1.x.x• Drafts proposed for approval

are version 2.x.x• On approval, GSM specs became

version 3.x.x = Phase 1• Or version 4.x.x = Phase 2• Or version 5.x.x = Phase 2+ R96• Or version 6.x.x = Phase 2+ R97• Or version 7.x.x = Phase 2+ R98

• Or version 8.x.x = Phase 2+ R99


The same scheme was adopted for UMTS …• Early drafts of specs are version 0.x.x• More stable drafts are version 1.x.x• Drafts proposed for approval

are version 2.x.x• On approval, UMTS specs became

version 3.x.x = R99


Prior to R99, the Release of a spec could be determined simply by looking at its version number:• 3.x.x = Phase 1• 4.x.x = Phase 2• 5.x.x = Phase 2+ R96• 6.x.x = Phase 2+ R97• 7.x.x = Phase 2+ R98• 8.x.x = Phase 2+ R99


But in R99 GSM systems were composed of some old, single-purpose, specs such as03.71 version 8.x.xand some new, dual-purpose, specs such as22.016 version 3.x.x

This made it difficult for outsiders without knowledge of this history to comprehend !


So …


For the next Release it was decided to renumber all the “pure” GSM specs :

GSM R99






06.-series CODECs






12.-series OA&M

GSM Rel-4






46.-series CODECs






52.-series OA&M


And, to align with the new UMTS spec number format, an extra digit was added after the dot:

05.xx → 45.0xx

So, for example, an old GSM R99 spec

05.04 “Modulation”

became, in Rel-4, the (GSM-specific)

45.004 “Modulation”

and 05.04 does not exist in Rel-4 and beyond.


This allowed harmonization of the version numbers:

05.04 “Modulation” version 8.x.x = R99

became

45.004 “Modulation” version 4.x.x = Rel-4

In Rel-4 (and beyond), all specs have a common version first digit:

45.004 version 4.x.x 22.016 version 4.x.x

… and this is why it is called “Release 4” !


Since the initial re-numbering, other spec series have been added.

GSM early






06.-series CODECs






12.-series OA&M

GSM later






46.-series CODECs






52.-series OA&M

55.-series

UMTS






26.-series CODECs






32.-series OA&M

33.-series Security

34.-series UE & USIM test specs

35.-series Algorithms


And also more technologies …

33.-series Security



LTE

36.-series LTE Radio

GSM/EDGE – UMTS – LTE

37.-series Multiple radio technologies


Also …• The part of the spec number following the dot has a degree of logic behind it.

Where possible, a correlation is retained from one stage to the next:• Feasibility study report 22.982, 23.872, 29.882 CAT studies• Stage 1 spec 22.182 CAT stage 1• Stage 2 spec 23.182 CAT stage 2• Stage 3 spec 24.182 CAT stage 3

• TRs are in two ranges:• xx.9xx Intended for publication by partner SDOs• xx.8xx 3GPP-internal
