Overview of 3GPP Release-12 Study Item UPCON
Mobile operators are seeing significant increases in user data traffic. For some operators, user data traffic has more than doubled annually for several years. Although the data capacity of networks has increased significantly, the observed increase in user traffic continues to outpace the growth in capacity. This is resulting in increased network congestion and in degraded user service experience. Reasons for this growth in traffic are the rapidly increasing use of smart phones and tablet like devices, and the proliferation of data applications that they support, as well as the use of USB modem dongles for laptops to provide mobile Internet access using 3GPP networks. As the penetration of these terminals increases worldwide and the interest in content-rich multi-media services (e.g. OTT video streaming services) rises, this trend of rapidly increasing data traffic is expected to continue and accelerate.
Here are couple of presentations on this topic:

LTE-B, LTE-C, ... , LTE-X
Please make sure to read the comment from Kevin Flynn of 3GPP at the end
When I saw this picture above, I started wondering what LTE-B, etc. and started digging a bit deep. Came across this Ericsson presentation (embedded below) that shows the breakdown.
To just be sure that this is not Ericsson specific term, I also found a presentation by NTT Docomo (embedded below)
So I guess using LTE-B, LTE-C, etc. is better than saying 4.1G, 4.2G, etc. as we did in case of 3G/HSPA.
The presentations from Ericsson and NTT Docomo embedded below, available to download from Slideshare.

LTE / EPC Signalling Training from eXplanoTech
Training is one of the areas we have been focussing on for a long time. Due to lack of bandwidth we have only been offering our training to a selected few customers but we are now expanding further. Here is a sample of LTE / EPS Signalling training

Videos from the CES 2013
Gorilla glass (above) is made by a company called Corning that is much more well known for its futuristic video, see here.
Finally, this Sony Xperia Z has got over 2 million hits, not exactly sure why so I have added the video for this as well

The four C's of Release-12 enhancements
Mid last year, I did a post on the LTE Rel-12 workshop and later another post on the progress. Late last year, 3GPP posted a news item that the Rel-12 will be available by June 2014 and the main areas of focus will be as follows:
Nokia Siemens Networks (NSN) has published their own whitepaper on 'LTE Release 12 and Beyond' (available on Slideshare here).
The following is their take on the four C's:
Release 12 enhancements focus on the four areas of Capacity, Coverage, Coordination (between cells), and Cost. Improvements in these areas are based on using several technology enablers: small cell enhancements, macro cell enhancements, New Carrier Type (NCT) and Machine-Type Communications (MTC). These enablers are described in this paper.
Customer experience, capacity and coverage will be improved with small cell enhancements, based on inter-site Carrier Aggregation, LTE-WLAN integration and macro cell enhancements. Small cell enhancements are also known as enhanced local access.
NCT helps achieve the required changes in the physical layer and initially provides base station energy savings, flexibility in deployment and ways to reduce interference in heterogeneous networks (HetNets).
Improvements in capacity and a more robust network performance are achieved by 3D Beamforming/MIMO (Multiple Input Multiple Output), advanced user equipment (UE) receivers and evolved Coordinated Multipoint (CoMP) techniques, as well as through Self-Organizing Networks for small cell deployments.
Finally, new spectrum footprint and new business will be opened up by optimizing the system for Machine-Type Communications, as well as by, for example, using LTE for public safety.
The whitepaper is available on Slideshare here.
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
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.

VoLTE, Battery Issues and Solutions
Sometime back we had news about how VoLTE is battery killer and how it would suck our 4G phones dry. Well, I agree. I am no fan of VoLTE and think that CSFB solution can suffice in mid-term. Having said that, there is a solution which would be soon available to sort this battery issue during VoLTE call. I had a post on this topic earlier titled SPS and TTI Bundling. I am not sure about exactly how much saving would occur if either of the features are implemented.
ST Ericsson has recently released a whitepaper on this topic that is embedded below. If you have more idea on this, please add it in comments.
