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:


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_UEPCOPMTCe_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.


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.

"No-Edge Networks" and Multi-Stream Aggregation (MSA)

The following is from Huawei press release:


The LTE-Advanced Multi-Stream Aggregation (MSA) technology standard is capable of increasing data rates at the cell's edge. A key component of Huawei's "No-Edge Networks" concept, MSA technology coordinates macro cells to improve user data rates at the cell's edge and also between heterogeneous networking scenarios to improve peak rates and simplify mobile management to ensure a consistent user experience.

With the development of mobile broadband, operators are mostly concerned about user experience. With mobile coverage, should able to enjoy the same quality of services no matter where they are. However, with mobile communication systems, the most challenging issue is system performance at the cell's edge.

The concept behind Huawei's MSA technology is that the user is always able to receive downlink data and aggregate downlink data streams from a cell or cell group with the best signal quality. A similar method applies to uplink data, where the user always transmits uplink data to a cell or cell group with the best signal quality. The uplink data streams are aggregated on the network side.

Huawei's MSA technology reduces the number of handovers, lowering device power transmission and increasing device standby time. These advantages are in accordance with the concept of delivering a "borderless network" and "green" wireless communications. It's expected that MSA technology will improve system performance at the cell's edge by almost 30%.

MSA technology is especially suitable for macro-micro HetNets. In hotspot area, macro cells provide basic LTE coverage while the micro cells provides capacity enhancement. The use of MSA technology allows users to receive controlled signaling from macro cells and services from best quality HetNet cell. Users at any location within the network can then enjoy fast and stable data services with ultra broadband, zero waiting and ubiquitous connectivity. MSA technology brings users high speeds and high quality as well as a simple service experience.

The advanced MSA technology proposed by Huawei is set to become a key feature of the evolution to 3GPP LTE-Advanced standards. Huawei has contributed 293 core standards to the 3GPP LTE/LTE-Advanced standardization process, 20% of the global total and the most of any other company.

I wasnt able to find much information but there is this couple of slides that were submitted in Rel-12 workshop that is embedded below:

LTE-Direct (rebranded Flashlinq) by Qualcomm

I blogged about Flashlinq before and also about the Proximity based Services (ProSe) and AllJoyn which probably is part of Release-12. Qualcomm is now proposing LTE-Direct that looks like a rebranded Flashlinq here. A video of that is embedded here.


From PCWorld:


Qualcomm is promoting a peer-to-peer cellular technology as a potential new standard called LTE Direct, which it says would make location-based services faster and more efficient.
The proposal grew out of FlashLinq, a system Qualcomm developed in its own labs. FlashLinq lets two cellular devices communicate over the air without relying on a fixed network infrastructure. Qualcomm sees two main applications for the technology: public safety communications in areas where mobile networks are down or unavailable, and a "discovery mode" that provides information about what interesting things and people are nearby. Qualcomm is primarily interested in the discovery mode, which it says has more commercial potential.
LTE Direct eliminates steps in the location process, allowing users to find things more quickly, Qualcomm says. Though the technology can be used for ongoing communication at high speeds, including streaming video, in discovery mode it would only broadcast tiny 128-bit packages of data. Those packages, called "expressions," would contain basic information about the device or user. Each LTE Direct device would look for expressions nearby, choosing among them using filters customized for the user or for specific applications.
"What you do is, every so often, you broadcast this 128 bits of information, which are expressing your desire ... so devices and services around you can listen to (your expressions) and figure out what you're interested in," said Mahesh Makhijani, senior director of technical marketing at Qualcomm.
Mobile consumers as well as businesses could send and receive expressions. If an application detects an expression that's relevant to what it does, that application can then go into action, providing something to the user. For example, if two friends have devices that are sending out expressions, then a social-networking app that both of them use might pop up notifications for each saying the other friend is nearby. A classic example of an application that might take advantage of discovery mode is the location check-in app Foursquare, Makhijani said.
Decentralized process
Current location-based services rely on a central database of location data. Every party's location, determined by GPS or other methods, has to be collected in that database and then sent out to other interested parties who request it, Makhijani said. LTE Direct finds nearby devices directly over the air.
Finding a match between one user and other people or services nearby is also quicker, because "service layer" information is contained in the 128-bit expression, Makhijani said. That service layer information determines whether something is of interest to you, such as whether someone uses Facebook and is a friend, or whether your favorite store nearby is offering a deal. To determine these things with LTE Direct, it's not necessary to query a central server over the Internet or even to establish a dedicated connection with the nearby device, he said.
LTE Direct isn't intended to provide exact location or replace GPS for finding out exactly where you are, but it could complement existing location systems and speed up the process of finding out where you are, Makhijani said. Its benefits include the speed of proximity-based location as well as its ability to work indoors, where GPS often has trouble getting a fix because it relies on satellites, he said.

3GPP based 'Sponsored Data Connectivity'


One of the features being investigated and added is the Sponsored Data Connectivity feature in the Evolved Packet System. This feature has lots of backers as this is deemed to be a new source of revenue for the operators.

In Release-10 one of the items for this is titled 'Policy Enhancements for Sponsored Connectivity and Coherent Access to Policy related Databases (PEST)'

The justification for PEST is as follows:


With the emerging of innovative IP services, the transactional data usage is becoming more and more prevalent on the mobile. For example, the user downloads a purchased ebook from an online store; the user purchases and downloads a game from an operator store; the user views free trailer clip from an online library to determine whether to buy the entire movie or not. In many cases, the Sponsor (e.g., Application service provider) pays for the user’s data usage in order to allow the user to access the Application Service Provider’s services. This enables additional revenue opportunities for both the Application service providers and the operators.


In particular, such dynamic data usage provided by the Sponsor allows the operator to increase revenues from the users with limited data plans. The user may have limited data plans allowing only a nominal data volume per month and the Sponsor may dynamically sponsor additional volume for the user to allow access to the services offered by the Application service providers.


The PCC framework can be enhanced to enable such use cases, in particular, it allows the operator to provide service control based on such sponsored services. For example, it allows a dynamic IP flow to be excluded from the user’s data plan since a Sponsor might sponsor the data usage for the identified IP flows. For example, the user may use the limited data plan to browse an online store for interested books; but once a book is purchased, the data usage for downloading the book can be granted for free. In addition, the IP flow may also be granted certain level of QoS (e.g. video streaming).



TR 23.813 studied the feasibility of these scenarios of sponsored connectivity in the key issue 1 and converged into a set of extensions to the PCC procedures which will allow the operator to provide sponsored connectivity to sponsor entities.


In addition to Key Issue 1, SA2 also studied the feasibility of Key issue 2 - Coherent access to Policy related databases within TR 23.813. It enables UDR (User Data Repository) in the PCC architecture as an optional functional entity where PCC related subscriber data can be stored and retrieved by the PCRF through the Ud interface. This deployment scenario does not require SPR and allows the PCRF access to the PCC related subscriber data stored in the UDR.

In Release-12 PEST is linked to another new feature titled, 'Interworking between Mobile Operators using the Evolved Packet System and Data Application Providers (MOSAP)'

The Justification of this is as follows:


Mobile operators have to deal with increasing flexibility of data services delivery on different devices. 


The data services could be hosted by the mobile operators in their data centers within 3GPP domain or could be hosted by 3rd party data application providers that could be outside of the mobile operator domain. 


Current practices involve individual mobile operators negotiating agreements with data application providers resulting in proprietary additional functionalities in 3GPP networks which results in  non-standard 3GPP interfaces. With the advent of new models of services delivery like cloud computing and Application Stores, it is important that the mobile operator minimises upgrades to the network  and associated backend integration. 


Also the mobile operator has the opportunity to explore various charging models in this interworking scenario with data service providers. 


Sample services/capabilities that mobile operators can provide to data application providers are customised billing/charging, promotional services, group addressing capabilities, identity services, statistics, etc.


This WI proposes to enable the mobile operator to use enhanced functionalities and interfaces to meet the needs of the rapidly changing industry models. The WI is expected to develop requirements and architectural frameworks for authentication, authorization, policy, charging, mobility and session continuity aspects for various interworking scenarios.


The existing schemes for authentication/authorization and charging need to be studied and updated/enhanced, when deemed necessary, by liaising with other 3GPP Working Groups/SDOs/fora in charge of them.


This WI was de-prioritised in Rel-11. The Rel-12 work will take into consideration the new TS 23.682 developed in Rel-11 (Architecture Enhancements to facilitate communications with Packet Data Networks and Applications).

What are you your thoughts on sponsored data connectivity?

I had a quick discussion with Dean Bubley on twitter and here is what he thinks:

Key question is what use cases & how the biz model / sponsor interaction works. 1-800 model is a #UselessCase for example. I think tollfree/1-800 apps is a nice idea, but totally unworkable when you drill into the practicalities. There are a few corner-cases & niche exceptions (eg govt-supplied apps) but proposed case for general apps / content is a chimera. 

More details on what Dean Bubley means is on his blog post here.

The comment at the end is very interesting, summarising the hurdles that exist in providing 'Toll-free data'.

My belief is that since the operators are running out of the options in generating new revenues, they may make a compromise and find a middle ground for making the 'Sponsored-data' to work

3GPP Recently held a workshop on "Release 12 and Onward" to identify common requirements for future 3GPP radio access technologies. The goal of the workshop is to investigate what are the main changes that could be brought forward to evolve RAN toward Release 12 and onward. It is recommended that presentations in the workshop include views on:
- Requirements
- Potential technologies
- Technology roadmap for Releases 12, 13 and after

The discussions from the workshop should be used to define the work plan for Release 12 and onward in TSG-RAN.
