3. 3G and GSM Specification Handling 3G and GSM Specification Handling Endorsed by: –3GPP TSG-SA. –3GPP TSG-CN. –3GPP TSG-T. –3GPP TSG-RAN. –ETSI SMG#29 (with modifications) PCG#2 (with SMG#29 modifications) ETSI Board#20 (with SMG#29 modifications)

4. Rationale 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.

5. Rationale 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.

6. Decisions 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 3 rd Generation Core Network specifications as GSM specific parts if necessary.

7. Decisions : 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 (<R99) of the Specifications transferred becomes the Responsibility of 3GPP.

8. Decisions : Decisions : Relevant SMG e-mail lists are sent CRs to <R99 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

9. Decisions: 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.

10. Decisions: Decisions: The GSM Specifications database(s) and status lists are maintained. All < 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).

11. Decisions: 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.
