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 itemany 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

WAY FORWARD, POINTS TO CONSIDER
OrganisationWill continue to grow
Release contentWill be driven by the 3GPP members
Access footprintSatellite ??
System enhancementsBroadcast ??
Architecture evolutionWill the core continue to introduce new nodes ??
Will the CS-domain be removed ??
Will the home network control be discontinued or minimised ??
Will all network-functions continue to evolve ??
Will we see new ways of design of networks??
KEY MESSAGES
3GPP is fully focused on:
Providing the industry with timely
evolution of a robust system
Prioritizing new features via the
3GPP Release process, as the best
means of delivering 5G
successfullysuccessfully
Seeking improvements both from
process and technology point of
view
Preparing the network for a
substantial increase of traffic from
a highly diverse amount of clients
Thank You...
