New Opportunities for 3GPP in Rel-12

Dec 14, 2012
An objective look at the next 18 months work for 3GPP TSG SA has identified priorities for Release 12 and started the decision making process for what can be achieved by its completion - scheduled for June 2014.

The amount of time available to 3GPP to get features specified is always limited, so it is inevitable that member companies need to make difficult decisions on whether to put their resources in to one work item or another.

A workshop was held during the 3GPP Service and System Aspects (SA) 58th plenary meeting, covering the non-radio aspects for prioritization. However, many of the delegates stressed that it was important to keep both the 3GPP RAN and the 3GPP SA priorities in mind.

Following the workshop, SA has agreed on three broad strategic areas (below) for Release 12 prioritization and allowed for further consideration - on some other features – for decision at the next plenary, in March 2013.

Exploiting new business opportunities

  • Public Safety and Critical Communications
  • Group Communications (GCSE_LTE)
  • Proximity Services, including both Public Safety and Commercial aspects (ProSe)
  • Machine Type Communications
  • UE Power Consumption, Small Data and Device Triggering (MTCe_UEPCOP, MTCe_SDDTE )

WiFi integration

  • Network Selection aspects (WLAN_NS)
  • S2a Mobility with GTP for WLAN (FS_SaMOG)
  • Optimized Offloading to WLAN in 3GPP-RAT mobility (FS_WORM)

System capacity and stability

  • User plane congestion (UPCON)
  • Core Network Overload (FS_CNO)
In addition to those three areas, other features can still be considered for completion in the Release 12 timeframe. The SA2 Working Group - responsible for Architecture - will produce time budgets to see whether further priority could be put on;

  • Pure IMS features that can run in parallel with key items
  • Policy and Charging Control for supporting fixed broadband access networks, PCC for fixed terminals (P4C BB1 and BB2)
  • Application Based Charging (FS_ABC)
  • User Monitoring Control Enhancements (FS_UMONC)
  • LIPA Mobility and SIPTO at the Local Network (LIMONET)
  • Operator Policies for IP Interface Selection (OPIIS)

Working Group SA2 will provide time budgeting information, for the selected features, at the next Plenary meeting - TSG#59 , in March 2013.
