1 © 3GPP 2009 Mobile World Congress, Barcelona, 19 th February 2009© 3GPP GPP The Training Course / Module 12a 1 All you always wanted to know about 3GPP … but were too afraid to ask. The 3GPP Seminar

2 © 3GPP 2009 Mobile World Congress, Barcelona, 19 th February 2009© 3GPP GPP The Training Course / Module 12a 2 The 3GPP Seminar Module n Hints for Getting Results - a guide for chairmen

3 © 3GPP 2009 Mobile World Congress, Barcelona, 19 th February 2009© 3GPP GPP The Training Course / Module 12a 3 3GPP Working Methods are Tools Choosing the right tool for the job is the Chairmans Task

4 © 3GPP 2009 Mobile World Congress, Barcelona, 19 th February 2009© 3GPP GPP The Training Course / Module 12a 4 Picking the Right Tools for the Job Starting Work Priorities Coordination Getting Agreement Finishing Work

5 © 3GPP 2009 Mobile World Congress, Barcelona, 19 th February 2009© 3GPP GPP The Training Course / Module 12a 5 Starting Work Start it as a WID Feature/BB/WID WG/TSG Wide/3GPP Wide Scope can change over time Can include TR work Start it as a SID Good when a solution isnt clear Brainstorming often done in xx.8xx series specification Do it as TEI Only when resolved in a single meeting and single CR Do it first and ask for permission later Not recommended, but happens The Workplan is a tracking tool not a work approval tool Should be aligned with WIDs/SIDs at Feature/BB level

6 © 3GPP 2009 Mobile World Congress, Barcelona, 19 th February 2009© 3GPP GPP The Training Course / Module 12a 6 Work priorities 3GPP is contribution driven Priorities may be decided on WG or TSG level TSGs can coordinate work across groups SA can make across 3GPP prioritization The completion date in the WID or SID Date is typically a sunny day estimate Chairmans job is to try and make estimates as realistic as possible Dont spend too much time on completion date – Ultimate outcome depends on when then work completes Meeting Time Allocation Encourage offline discussion Ah-Hocs or meetings with restricted scope Subworking groups Agenda allocation Allocating to a release Should not be discussed at WG level (TSG level discussion) Early implementation mechanism defined in 3GPP (rarely used) Release independent mechanism not defined in 3GPP (often used)

7 © 3GPP 2009 Mobile World Congress, Barcelona, 19 th February 2009© 3GPP GPP The Training Course / Module 12a 7 Coordination Coordination between 3GPP groups Company (Individual coordination) Status reports Chair tasked with coordinating with the group Liaision statements Colocated meetings Joint meetings <- Most joint meetings are not formally joint meetings Coordination with groups outside 3GPP Company (Individual coordination) Chair tasked with coordinating with the group Liaision statements Colocated meetings Joint meetings <- Usually not possible ITU coordination is special Conflict with National Positions toward ITU Special coordination groups for ITU-T and ITU-R If to become part of an ITU deliverable then needs to go to PCG

8 © 3GPP 2009 Mobile World Congress, Barcelona, 19 th February 2009© 3GPP GPP The Training Course / Module 12a 8 Formal vs Informal Agreement Informal Tools Consensus in the meeting Consensus on Chairs edict Formal Tools Vote Working Agreement

9 © 3GPP 2009 Mobile World Congress, Barcelona, 19 th February 2009© 3GPP GPP The Training Course / Module 12a 9 Consensus Building Tools Coffee break/offline sessions Appoint a coordinator that you can rely on to be fair Ensure the scope of the offline discussions are clear Ensure people know who to contact for inclusion Postponement until later in the meeting A bit like offline sessions, but less organized (usually if companies arent objecting but request more time) Indicative Show of Hands If asked then by company* – companies generally vote by IM Questions dont need to be as formal as voting questions Discussion until Exhaustion Late sessions on a topic Generally leads to bad agreements as fuzzy agreements can be reached Chairmans Compromise If the two sides are close, then propose a specific compromise. Proposals from the chair carry extra weight *Note: unless it is something like meeting hours and then it makes more sense to do it by delegate

10 © 3GPP 2009 Mobile World Congress, Barcelona, 19 th February 2009© 3GPP GPP The Training Course / Module 12a 10 Discussions Useful for preliminary consensus building When there are very few views on an issues Companies have more time to consider views Useful for specific, limited decisions approvals can be done Needs a specific coordinator and deadline Not very useful for critical decisions Hard to judge overall sense of the group Discussions can become multi-threaded and hard to follow

11 © 3GPP 2009 Mobile World Congress, Barcelona, 19 th February 2009© 3GPP GPP The Training Course / Module 12a 11 Understanding Roots of a Conflict Understanding the base rational is a key step to resolving the issue Between Operators Differences in deployment strategy IPR considerations Technical disagreement Between Vendors Already developed or planned products IPR considerations Technical disagreement Between Operators and Vendors Deployment options vs common evolution IPR considerations Technical disagreement

12 © 3GPP 2009 Mobile World Congress, Barcelona, 19 th February 2009© 3GPP GPP The Training Course / Module 12a 12 Finishing Work Work may or may not be tracked in a report Done by RAN Terms often used in specs Information (60% of development work) Approving (80% of development work) Frozen (99% of development work) [By Release] Deep Freezing [FASMO] (95% of errors fixed) [By Release] Closed (100% of errors) [By Release] Tentatively allocated to a release by SA Freezing by Stages Exceptions required if past freeze date Some TR (or TS) may be abandoned Often happens with 800 series TRs
