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
