7 Membership 3GPP Working Procedure highlights Open to members of 3GPP Organizational Partners Decision making 1 member 1 vote Voting rights are earned: member added to voting list if attends 2 meetings, removed from list if he misses 3 consecutive meetings Proxies permitted Access to information All working documents open to the public All lists open to the public Meeting participation restricted to 3GPP members Meeting documents, lists, next meeting details etc.: 3GPP

8 Release-based work 3GPP Working Procedure highlights Releases or major packages of Features Work plan built using Features, Building Blocks and Work Tasks Work Item Description exists for each of these WI may cover more than one specification WI may cover more than one committee WI Description document exists for each WI Multiple releases maintained in parallel 3GPP WorkPlan: 3GPP

9 Ways of working New work initiated by member companies via Work Items outlining scope and time plan. Work Items prioritised if all estimated work cannot be done by the scheduled release deadline. All 3GPP member companies contributes on equal terms on any work item 3GPP seeks consensus on all technical matters (but has mechanisms if consensus cannot be reached) Release deadline respected, unfinished work deferred to a later release 3GPP

10 Maintaining multiple releases Change Control Each release progressively frozen as it is developed Specifications pass under Change Control Rapporteur may no longer update drafts All changes managed by TSG Change Request process to introduce corrections/updates Package of CRs approved 4 times per year at TSG Plenary meeting CR database: CRs also searchable per specification via 3GPP website CR process provides full traceability of all changes to every specification Release and CR process closely related to network equipment development and supply contracts 3GPP
