3G and GSM Specification Handling

• Endorsed by
• 3GPP TSG-SA.
• 3GPP TSG-CN.
• 3GPP TSG-T.
• 3GPP TSG-RAN.
• ETSI SMG29 (with modifications)
• PCG2 (with SMG29 modifications)
• ETSI Board20 (with SMG29 modifications)

3
Rationale

• 3GPP require a complete set of 3G specifications.
• 3G specs based on the GSM CN.
• Divergence of evolved GSM and 3G should be
  avoided if possible.
• Duplication of development work should be
  avoided.
• Creation of almost identical sets of
  Specifications should be avoided.

4
Rationale

• Technical corrections to earlier GSM Releases
  will impact the later 3G versions of the
  specification, requiring CRs to all versions.
• Fine tuning of previous GSM Releases will
  continue into 2000.

5
Decisions

• To avoid divergence
• Maintenance and evolution of common
  specifications should be responsibility of one
  Technical Body.
• To avoid duplication of work
• GSM evolution (GSM R99 onwards) should be
  incorporated into the 3rd Generation Core Network
  specifications as GSM specific parts if necessary.

6
Decisions

• TSG WGs and corresponding SMG STCs co-locate
  meetings.
• GSM Specifications modified in anyway for the 3G
  are transferred to 3GPP.
• 3GPP produce a complete set of 3G R99
  specifications.
• Maintenance of all previous GSM Releases (ltR99)
  of the Specifications transferred becomes the
  Responsibility of 3GPP.

7
Decisions

• Relevant SMG e-mail lists are sent CRs to ltR99
  specifications prior to TSG approval.
• SMG approve all TSG CRs to earlier releases of
  the GSM Specifications, which are ETSI
  deliverables.
• SMG review all TSG CRs to R99 and later releases
  of the 3G Specifications which impact on GSM

8
Decisions

• SMG delete/stop all GSM R99 versions of the
  Specifications which are transferred to 3GPP.
• Remaining GSM Specifications will continue to be
  maintained and developed within SMG.
• 3G Specifications may contain GSM R99 Specific
  parts.

9
Decisions

• The GSM Specifications database(s) and status
  lists are maintained.
• All lt R 99 and the Specifications only relevant
  for GSM are maintained on the SMG ftp site.
• SMG (for ETSI) approve the 3G specifications that
  are released to the POs, which are to become ETSI
  deliverables.
• SMG (for ETSI) decide the 3G specifications ETSI
  deliverable type (EN, TS etc).

10
Decisions

• SMG provide only a replacement cover, Foreword
  and History to the 3G specifications, leaving the
  3GPP version number intact.
• SMG provide ETSI Public Enquiry comments on 3G
  Specifications to the appropriate TSGs.
• A complete set of specifications for GSM R99 and
  onwards should be identified.
