Oracle: LTE Diameter Signaling Traffic will Grow @68% CAGR

Oracle's new study “Oracle Communications LTE Diameter Signaling Index, Fourth Edition" finds "a massive increase in LTE Diameter signaling traffic ..  Oracle forecasts that LTE Diameter signaling traffic will grow at a compound annual growth rate (CAGR) of 68 percent in the next five years, from 30 million messages per second (MPS) in 2014 to 395 million MPS by 2019:

• LTE Broadcast is the fastest-growing generator of Diameter signaling traffic, creating 49.5 million MPS by 2019 at a CAGR of 75 percent. The technology is just emerging, and continued growth is expected as CSPs trial LTE Broadcast for everything from digital signage to live video feeds at sporting events
     
• Policy continues to drive the majority of Diameter signaling traffic, creating 277 million MPS. With more-sophisticated policy use cases, the number of Diameter transactions between policy enforcement points and charging has increased
   
• Mobility will generate 25.3 million MPS by 2019. It is currently not a major factor in overall Diameter signaling traffic generation, because it creates a low number of transactions in the Diameter network
     
• Voice over LTE (VoLTE) will generate 43.1 million MPS at a CAGR of 49 percent by 2019

[Infonetics]: DSC Market to Reach $1.3B by '18; Led by Huawei, F5 and Oracle

A new report by Diane Myers, Principal Analyst, Infonetics Research finds that ".. the Diameter signaling control market will grow threefold between 2014 and 2018, to $1.3 billion .. Globally, the Diameter signaling control market totaled $381 million in 2014, an increase of 81 percent over 2013.

Developed as the next-generation signaling protocol, Diameter has begun to permeate networks, driven by increasing LTE usage and the emergence of VoLTE (voice over LTE). As a result, the Diameter market spiked 81 percent in 2014 from the previous year.

The Diameter vendor landscape is beginning to shake out: 

[See my product list page - here]

• it’s a tight race at the top between Huawei, F5 and Oracle. 
• We see a strengthening of Ericsson and a push from Alcatel-Lucent, Sonus and now Mavenir with its acquisition of Ulticom [see "Mavenir Turns Ulticom OEM to Acquisition" - here] 
• The consolidation continues, and we expect even more in 2015

The top use case for Diameter signaling control in 2014 was once again centralized routing, but roaming via DEA (Diameter Edge Agent) was right behind"

[Research]: VoLTE is Better than OTT VoIP

Mobile networks vendors continue to claim that their built-in VoIP (VoLTE) beats OTT's VoIP in all aspects - efficiency,performance and quality.

We saw internal research from Nokia - see "NSN: VoLTE Beats OTT VoIP 4:0 !" - here and "Nokia: VoLTE is Doing Better than OTT's VoIP Under Load" - here.

Alcatel-Lucent joins the trend and announces "the results of an independent research study [Signals Research Group, here] which found that its commercially deployed Voice-over-LTE (VoLTE) technology provides better service than 3G Circuit Switched (CS) voice and Internet calling services and Skype software. The analysis found that VoLTE users enjoyed considerably better call quality, faster connectivity and substantially less drain on the batteries of their mobile devices"

• VoLTE call quality greatly exceeded that of 3G CS voice and was measurable higher than the HD voice service offered by Skype
   
• With network loading, and in particular with background applications running on the mobile phone and transferring data with the network, the VoLTE results were considerably better than Skype
   
• VoLTE call setup time was nearly twice as fast as 3G Circuit Switched Fallback (CSFB) call setup
   
• VoLTE used substantially fewer network resources than Skype voice, which in turn resulted in longer estimated device battery life for the subscriber and a more efficient network for the operator
   
• When leaving LTE coverage, VoLTE calls were successfully handed over to 3G CS voice. The network’s enhanced Single Radio Voice Call Continuity ensures calls continue without interruption

[ALU]: "signalasis" Undermining Customer Experience and Operator’s Reputation

An article by Josee Loudiadis [pictured], Director of Network Intelligence, Alcatel-Lucent, covers the "signaling spikes that can overwhelm available signaling capacity, undermining the customer experience and the operator’s reputation with it" and analyzes the signaling behavior of several common applications.

"There are three kinds of “signalasis”: microbursts that can be measured in seconds, extended bursts that can last minutes to hours, and suddenly sustained signaling growth where signaling jumps significantly at one point in time and continues to increase over weeks and months. Facebook’s 60% jump on Nov 2012 is an example of the latter" 

• Extended bursts Viber outage: 

GGSN experiencing 92% jump in signaling
 for 4 ½ hours during Viber outage

On April 29th, CPU overload alarms reported that RNCs (Radio Network Control) were inundated with requests. The signaling spike could be matched to Viber – flows showed that Viber servers were no longer responding. Viber was down. But, why would this app outage have such a significant impact on signaling resources? The answer is in Viber’s call failure handling: the app would retry repeatedly to connect with the server, creating a larger signaling wave as more users tried unsuccessfully and repeatedly to connect. 

• Microbursts:   Microsoft Exchange and iOS: 

GWs subjected to 36% signaling microburst at midnight
due to iOS-based Microsoft Exchange

This case exemplifies other short term outages where the signaling spike exceeded the signaling capacity on a daily basis. A 36% signaling jump occurred everyday at midnight, but the reason for the spike remained mysterious. The WNG narrowed it down: the signaling was initiated by devices trying to reach the Microsoft Exchange server. This interaction lasted less than 1 second in duration. It only involved iPhone devices and was more predominant with iOS version 6.1. Equipped with this information, operators could contact Apple and identify the root cause. A fix was issue in a subsequent iOS version update

ALU Identifies the Chatty Mobile Apps

A new report by Alcatel-Lucent ",, examines the impact of leading mobile applications on service provider networks and on consumers’ data plan and device battery life .. The rankings in this report are derived from mobile network analytics provided by the Alcatel-Lucent Wireless Network Guardian [see "Softbank [Japan] Uses ALU for Better QoE" - here]. All measurements are based on actual app usage by more than 15 million subscribers on live 3G mobile networks in North America, APAC and the Middle East"

Key findings:

• Apps that impact the network due to their high data volume — a group that includes most video apps, along with iTunes®, Instagram, Pinterest, Apple Maps and Pandora — are targets for bandwidth optimization. One service provider reduced cell utilization by an average of 20% after introducing selective traffic optimization.
   
• The apps with the biggest impact on the consumer data plan are YouTube, Netflix, Facebook Video, Pandora and Video on Instagram.
   
• The apps in the High Signaling quadrant are perfect candidates for code design optimization aimed at reducing the number of times the device and network must establish communications
  
  
  

Bandwidth optimization success story: Selective traffic optimization

A service provider knew that the key to managing traffic cost was to manage the peak hour. The peak hour drives CAPEX investment, so logic dictated that reducing the load at that critical time would reduce the need for investment. Studies of  peak-hour traffic revealed a surprising fact: that the typical heavy users were not active during this period. Each day, a different set of users topped the peak-hour volume chart. Throttling certain users during a certain period of the day would not help the service provider reduce utilization.

The service provider selected a two-part mechanism to optimize traffic. The first part involved using network analytics (specifically, an algorithm relying on utilization and subscriber QoE metrics) to determine when congestion occurred, relay the severity of the congestion, provide a list of subscribers currently attached to the cell, and rank these subscribers by data volume. The second component was to use a policy manager to decide whether specific users should be throttled, how many users should be throttled and for what period of time they should be throttled. The service provider reduced cell bandwidth  by an average of 20% and reduced the amount of time cells spent in congested state each day by 60%.

NSN: VoLTE Beats OTT VoIP 4:0 !

Gerald Reddig [pictured], Nokia Solutions and Networks, explains in company's blog why VoLTE is good for MNOs - technically.

"NSN Smart Labs recently tested both client groups, OTT VoIP and VoLTE" and found that in all 4 measured KPIs VoLTE is better:

• VoLTE clients consumed approximately 40% less than OTT VoIP clients.
   
• OTT VoIP clients generated up to 10x more data connections in the mobile network than a VoLTE client during a call
   
• Most OTT VoIP applications required between 20% and 40% more throughput than VoLTE clients during active calls to achieve this quality level, although one OTT VoIP application showed exceptional performance and came close to VoLTE. Overall data volume consumed over a period of time, including a mix of active and stand-by periods, resulted in at least 50% lower consumption for VoLTE thanks to its more efficient behavior during stand-by
   
• Typical default OTT VoIP keep-alive patterns activated during standby created between 100% and 200% higher signaling load on LTE networks compared with VoLTE

See "Why operator VoLTE beats OTT VoIP" - here.

NSN: How can MNOs Deal w/OTT Resource Consumption and Lost Revenues?

A post by Andrew Burell [pictured], Nokia Solutions and Networks, to the company blog says that "OTT is certainly not a lost cause to MNOs".

" .. [MNOs] see OTT applications such as Skype, WhatsApp and NetFlix piggy-backing on their network investments, clogging up resources and stealing their revenues. The figures themselves are certainly frightening. Every day 2,371 new applications are born, and a single ‘rogue’ app can generate 2,422 signaling messages per hour. By 2017, there will be 32 trillion messages sent by OTT messaging applications, and by 2020, operators stand to lose a cumulative total of $479 billion to OTT players.

.. With the right tariff structure for data-services in place, there are a number of different strategies that operators can successfully adopt to turn threat into opportunity. For example:

• Partnering with OTTs: ‘3’ offers subscribers a ‘Roaming Pass’ that allows them to use Whatsapp abroad with an inclusive data allowance
   
• Operators can launch proprietary services of their own: Verizon has followed this approach with its ‘Viewdini’ service – a mobile video aggregation portal that delivers mobile content from Netflix, Hulu and others.
   
• .. [NSN] Smart Labs and NPO (Network Planning and Optimization) expertise with performance proof points such as:
    
• Smart Labs research has shown that activation of WCDMA software suite features like Fast Dormancy Profiling can reduce signaling loads by 40%  [see "NSN: New Radio Software Reduces WCDMA Network Signaling" - here]
   
• Our NPO video optimization service was able to reduce content buffering by 30% for a major European operator

Oracle: Diameter Signaling Traffic Grows Twice Faster than Mobile Data Traffic

A recent research by Oracle (Tekelec) finds that "Long-term evolution (LTE) Diameter signaling traffic will grow at more than twice the rate of mobile data traffic through 2017, according to the second annual Oracle Communications LTE Diameter Signaling Index. The Index predicts that worldwide LTE Diameter signaling traffic will increase at a 140 percent compound annual growth rate (CAGR), from 1.2 million messages per second (MPS) in 2012 to nearly 99 million MPS by 2017". 

Tekelec's previous report predicted even higher CAGR - see "Tekelec Diameter Index Shows 252% CAGR Signaling Growth (2011-2016)" - here].

Source: Oracle Communications LTE Diameter Signaling Index: 

Forecast Report and Analysis 2012-2017

".. policy MPS are expected to more than triple in each of 2013 and 2014 compared with the previous year. By 2017, policy will account for 62 percent of signaling volumes .. The Index predicts that North America will be the largest contributor to Diameter signaling traffic each year in the forecast period. In 2017, the region is expected to reach nearly 43 million MPS".

NSN Warns MNOs: OTT Outages Increases Signaling (20X!)

A blog post by Gerald Reddig [pictured], Head of Smart Labs Marketing, Nokia Solutions and Networks, reports that "Recent OTT service outages in cloud service provided by Google hit mobile operator radio access networks with an unexpectedly high signaling load. Online services rely entirely on the service availability in large data centers provided by Google, Amazon and Microsoft, for example.

NSN Smart Labs verified that a cloud service outage can trigger smart phones to generate signaling loads up to 20 times greater than normal. This is an important heads up for mobile operators to prevent chain reactions that could lead to network outages .. For the test, NSN Smart Labs utilized one popular high-end Android smart phone. Now multiply that signaling storm by thousands of smart phones simultaneously and radio access networks would definitely be compromised".

[Survey]: RAN Congestion is Getting Worse

  

A new research by Graham Finnie, Chief Analyst, Heavy Reading (and Movik Networks) finds that "the majority of operators believe RAN congestion is getting worse, with half saying it is also less predictable .. the main objective of new RAN controls is to improve the customer Quality of Experience (QoE) .. and the need to improve the quality of operators’ key services, from controlling signaling congestion, to improving understanding of subscriber behavior and to monetizing features like QoE"

"Other key findings from the study 

• A majority of operators want real-time or near-real-time information on congestion when applying controls
   
• Operators want any controls to be applied holistically across all the networks they owned, with seamless control between 3G/4G and WiFi the biggest motivator
   
• Operators are looking for alternative, cost effective solutions to deploy RAN congestion control measures".

NSN: New Radio Software Reduces WCDMA Network Signaling

 
Nokia Siemens Networks launched "..new software applications for the Liquid Radio WCDMA Software Suite to help mobile broadband manage the smartphone boom and substantially reduce the network signaling overload .. 

• Fast Dormancy Profiling is a new Nokia Siemens Networks technology that identifies the legacy smartphones connecting to the network and eliminates the unnecessary signaling they often create. This application significantly reduces the air interface load on the Radio Network Controller (RNC). [see also "[NSN]: Chatty Android Phones should Move on to Network Controlled Fast Dormancy" - here]

• With Fast Cell PCH Switching, also a Nokia Siemens Networks technology, the network learns how specific smartphones are using the network services and shortcuts the signaling process for rapid call set-up, faster response from mobile broadband services and reduced signaling.

• High Speed Cell FACH enables networks to support more smartphones and provide faster services for subscribers using lower data volumes. It also significantly decreases signaling load between the RNC, base station and smartphone.

ALU: Signaling Issue with New Facebook

Lindsay Newell, VP, Marketing Networks & Platforms Group, Alcatel-Lucent, writes in a post to ALU's blog that "On November 15, Facebook released new versions of their mobile app for Android and iOS. Prior to the new release, Facebook signaling and airtime already accounted for 10% and 15% of the overall load on 2G/3G networks, respectively. As users around the world updated and started to use this new version, we quickly noticed a dramatic increase of almost 60% in the signaling load and 25% in the airtime consumed by the Facebook application. During the same period, the number of Facebook users increased by only 4%. Clearly, it is not the swelling of Facebook’s community that intensified the load, but rather the introduction of new Facebook features for mobile users and underlying platform changes .. The effect on service provider networks was significant, driving up overall (total) signaling traffic and airtime consumption by 5-10%".

"Another trend we detected was an increase in popularity of Facebook video traffic — a whopping 350% increase in volume since the November 15th launch — the most growth of all Facebook traffic".
