TSG_CN Meeting Schedule

• High density of working group meetings;– intend to go for less planned meetings to allow for

more e-mailing & ad-hoc “itemised” meetings.

• Various meetings are scheduled(see “yellow pages” or MCC web)

• 3 ad-hoc meetings on OSA CN-aspects took placemore are scheduled until CN#7

• ITU-T ad-hoc activity works by electronic means;little activity here

• IP-Kick-off 31st Jan-02nd Feb 2000

R

R‘99 / R‘00 General Treatment until CN#7

• Priority to R‘99 work-areas– open issues resolution

– debugging

– „negotiation of feasible content for R‘99“

– consideration of compatibility aspects

• Special attention to OSA, Multicall, Security

• Start of R‘00 with CN#7Exception: All IP-CN „Take-off“ meeting end Jan

s



R

R’00 All IP Core-network

• Kick-off meeting 31. January -- 02. February 2000

• P-00-118 Draft Report– Tutorial by S2

– Assessment by CN• architecture / services

• others (security,...)

– goal: prepare for decisions on what?, when?, who? at TSG#7

• Results– Joint Meeting with S2 agreed for April ‘00

Potentially some work transfer S2 --> CN working groups

– Tentatively some working group reorganisations

– Tentative allocation of work packages (interfaces) to workinggroups

s



R

R’99 Completion

• For R’99 completion the CN#6 established principles are:1) Exception from function freezing only allowed if stated in WI-

status sheets (SP-99602 (CN-view) and SP-99639 (SA#6 view))

2) Compatibility aspects for WI’s to be solved with R’99 (“Hooks”)

3) Specification of a restricted WI-subset for R’99

4) IF at CN#7• sufficient stability (incl. agreed documents) in work-area /sub-area

• no contentious issues

THEN R’99

ELSE R’00

s



R

Status on Multicall:

• Unclear requirements (stage1)

• No defined/approved basic assumptions(lack of „stage 1½ specification“ )– Supplementary Service CN working assumption now!!!!! or

– Network Feature or

– ????

• Interactions with other Supplementary Services (CW, CH)unspecified

• Prevention of incompatibilities eg/esp. in SCI area

• Workshop this week in Sophia Antipolis linked to SS-adhoc

s



R

Status on Multicall:

• Goal:– Stable documented principles end January

– identification of „viable Multicall phase1 R‘99“

– approval of resp. Material at CN#7

– Postponement of “add-on’s” to R’00 e.g. SCI

– CN not disputed WI to postpone to R‘00

s



R

Status on OSA

• Spirit: Give it a chance for R‘99

• Stabilise a first small release

• Refine on Scope for R‘99

• final decision CN#7

s



R

Status on security

• Spirit: Give parts of it a chance for R‘99

• Status– Parts stable in CN since long (Quintuple download, Data Integrity)

– Requirement for EUIC, MAP Security (GSM Benefit!!),Authentication Failure in 12/99 for R’99

• Unbundle security package and identify the essentials (--> S3)

• Joined meeting begin Jan analysed MAP requirements

• Review of situation at CN#7

• To Learn:– Earlier involvement of affected groups

joined CN-S3 meeting May 2000 on R’00 requirements

– Better WI management within CN (work task identification)

s



R

TSG_CN / SMG3 Relation

• SMG3 almost virtual no real work in SMG3 any more

• almost all specifications are shared/common specifications

• From SMG3/TSG_CN perspective separation inSMG(3) and TSG_(CN) is artificial and disturbing

• Maintenance work for SMG only specs acceptable under someconditions (own agenda item, no disturbance of common workflow)

s



R

TSG_CNFuture Modifications

• Step down of SMG3/WP-B and CAMEL group ChairmanSteffen Habermann (T-Mobil)– Successor election after clarification on

CN working groups reorganisation

– Attention for SS-maintenance!!

• Step down of SMG3 / TSG_CN Chairman (Harald Dettner)with SMG#31 resp. TSG_CN#7– For SMG3 no new elections are proposed

Mr. Ian Park (vodafone/airtouch) SMG3 vice chairman volunteeredto act as SMG3 interim chairman until ... tbd

TSG_CNSummary

• All delegates in CN WGs as well as support team work veryhard

• Not everything is complete

• For some WI’s a scope-reduction is already communicated

• Some WI’s dropped out– (L3 segmentation, Turbo-charger,...)

• Outstanding issues identified

• Refinement/Clarification for Multicall, OSA, Security R’99 withCN#7

s



R

TSG_CNSummary (2) / Outlook / Miscellaneous

• Improve Information Paths from CN to others• S3

• S2

• Limited time until & for CN#7 (2,5 Days)– Refinement scope / content R‘99

seek compromises in advance of CN#7

• Chairman Election at CN#7
