Welcome!

Welcome to the latest edition of TSG Highlights! The aim is to provide you with a concise summary of the decisions and actions of the most recent 3GPP Technical Specification Group meetings.

3GPP has four  TSGs: CT (Core Networks and Terminals); RAN (Radio Access Network); SA (Services and Systems Aspects) and GERAN (GSM EDGE Radio Access Network). 

Please note, these summaries do not constitute formal, approved reports of the meetings – they are opinions only and also may not be complete. They are offered for guidance only.

TSG CT (Core Network and Terminals)

TSG CT meeting #39 took place in Puerto Vallarta, Mexico. The meeting started on the 5th March 2008 and finished on the 7th March 2008.

Old releases:

•         No changes in R99

•         1 correction to a Rel-4 conformance test case

•         Corrections on Rel-5:

–        Correction to DTMF handling and to BNC event event handling in bearer establishment procedures

–        Both CRs were made under WI CSSPLIT

•         10 Rel-6 CRs, 2 of which were Cat A

–        Cat F corrections were made on the following work items:

–        IMS2: Mn profile, Removal of remote user from conference, correction of OMA DM reference

–        TEI-6: XML correction, Addition of “insufficient memory” error code for MBMS security procedures on the USIM

–        MMS6: Reference correction, addition of references to OMA DM procedures and MMS management object

–        MBMS: TMGI misalignment

Release 7 Overview:

- Rel-7 CR count is 31 % down since previous CT
- The number of Rel-7 Cat F CRs is expected to go down
- Changes and corrections on the following WIs:
- IMS related:
- IMS emergency calls
- Stage 3 IETF protocol alignment
- GRUU
- Service ID
- Multimedia telephony (Cat B. CR)
- Mp interface
- Voice Call Continuity
- Interworking between IMS and CS
- Fixed NGN (Packet Cable)
- PCC
- SMS over IP
- CSI
- other items:
- OSA
- WLAN QoS
- REDHOT, HUGE (capability indication only, no CT WID)
- TEI7

Release 7 Hot Topics:

•         Rel-7 CR count is 64 % down since previous CT

–        The number of Rel-7 Cat F CRs is still expected to go down

•         No contentious or critical issues to report

•         Corrections were made on the following WIs:

IMS related:

–        IMSProtoc

–        Mp interface

–        MIWIMS (MM interworking)

–        PCC

–        ServID

–        MTSI

–        FBI

–        TEI-7

Other items:

–        EVGCS

–        SDoUE

–        NSP-CR

–        IMS-CCR-IWCS

–        MBMS

–        TEI-7

Release 8:

•         Rel-8 CR count is a bit less than in the previous CT

–        30 new Rel-8 TSs were approved in CT #39

–        17 new Rel-8 TSs were provided for information to CT #39

–        11 new SAE specifications have been started recently

–        Main part of CT WG Rel-8 work is not yet seen as CRs in CT plenary

•         10 new WIDs and 8 updated ones were approved

•         Turkish SMS alphabet solution was approved

–        This is needed already in pre-Rel-8 UEs due to July 2008 deadline

–        SMS SENDING using locking shift cannot be implemented yet due to legacy

•         Contributions were received against several Rel-8 WIs:

–        Interface based on the SIP-I protocol

–        SAES (planning documents, WIDs)

–        Enhancements for VGCS applications

–        IMS items stage 3 IETF protocol alignment, IMS enhancements for packet cable access, NBA, MGCF interworking between UUS and SIP, Media server control using the IMS, PCC, TISPAN redoc, IMS-CS interworking, IMS for corporate access networks

–        TEI-8

SAE Status

•         SAE work has shifted from TR to TS mode

–        Separate WIDs from all affected WGs were approved

–        Protocol and interface mapping to TSs is done

•         PMIP vs. DSMIP

•         EMM and ESM are separate protocols with new PD assigned

–        New TSs have been started

•         TS numbers were already assigned by MCC

•         Transfer of material from TRs to TSs is ongoing

–        The whole CT SAE work has been planned

•         The identified new TSs either start now or have already been started

•         TRs 24.801, 29.803, 29.804 will continue as placeholders for material intended for already approved specifications until 09/2008

SAE work planning

•         CT is planning to complete SAE by Dec 2008

–        Full stage 2 of the included functionality is needed in SA #40

–        Any new functionality (Cat B or C CRs) introduced to Stage 2 after SA #40 should be considered as Rel-9 item or otherwise Rel-8 schedule will slip

–        Any new CT WID in SAE area would cause the Rel-8 schedule to slip

•         Dependencies (mainly) on SA groups

–        Dependencies to SA groups affect CT WG planning

–        CT agreed to continue to use 3GPP work plan as planning tool

–        Possibility to add TS maturity summary is being considered

•         Working group scheduling

–        CT1 and CT4 are running parallel IMS and SAE subgroups most of the time

–        CT1 and CT4 will have 6 more meetings this year

–        CT3 has (exceptionally!) 5 more meetings this year

–        SAE related informal phone conferences between the meetings

–        CT6 can accommodate SAE work in their normal meeting cycles

Common IMS

•         TISPAN transfer

–        Adopted TISPAN specification have been re-documented as 3GPP TSs

–        TISPAN R1 corresponds to 3GPP Rel-7 (TSs are in major version 7)

–        TISPAN R2 corresponds to 3GPP Rel-8 (TSs are in major version 8)

–        What was frozen by TISPAN is still frozen after transfer

–        28 re-documented TSs approved and 14 noted, see tdoc SP-080178

•         The transfer is now almost complete but 2 more TSs are expected for CT #40

–        CT4 proposes deprecation of Mp profile in ES 283 031 to TISPAN

•         3GPP MMD harmonisation

–        WG level workshop was held on the 24 – 25 Jan 2008

–        New work items related with MMD harmonisation were approved in CT #39

•         One framework WID and 2 more WIDs for individual features

–        New TS 24.238 SIP based user configuration

–        New TS 24.239 Flexible alerting supplementary service

–        New TS 24.182 IMS customised alerting tones

–        The first CRs have already been approved, but more work is expected under the new WIDs and related with the new TSs
