• Numbering scheme for TSs and TRs

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

  -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

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.

vocabulary, 02.-series Stage 1 (service

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 22.016 International
Mobile Station Equipment Identities (IMEI) and
02.16 does not exist in R99 and beyond.

02.16 International Mobile Station Equipment
Identities (IMEI) became, in R99, the common GSM
and UMTS 22.016 International Mobile Station
Equipment Identities (IMEI) 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 approvalare version 2.x.x
• On approval, GSM specs becameversion 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

10

• 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 approvalare version 2.x.x
• On approval, UMTS specs becameversion 3.x.x
  R99

11

• 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

12

• 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 !
13

• So

14
For the next Release it was decided to renumber
all the pure GSM specs
GSM R99 01.-series System requirements, rules,
vocabulary, 02.-series Stage 1 (service
requirements) 03.-series Stage 2 (abstract

protocols 06.-series CODECs 07.-series Data

e 3 Intra-core-network layer 3 protocols 10.-serie
s Work plan management (internal progress

e 3 Intra-core-network layer 3 protocols 50.-serie
s Work plan management (internal progress

specs 52.-series OAM
15
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.
16
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 digit45.004 version 4.x.x
  22.016 version 4.x.x

and this is why it is called Release 4 !
17
Since the initial re-numbering, other spec series
have been added.
