A change of ‘MooD’ for live streaming

Network

Posted on December 18, 2017

3 min read

A change of ‘MooD’ for live streaming as this world first technology helps avoid the “thousand dollar screen and ten cent stream” outcome.

With the explosion in real time consumption of mobile video streaming being driven by major events and sports, there is an emerging threat to the performance of mobile networks as peak demand may swamp network cell capacity.

The use of LTE-Broadcast technology changes the underlying efficiency of live video delivery as each cell can now support an unlimited number of users watching the same content with improved overall quality. To date though, LTE-B technology has required that a dedicated part of each cell’s capacity be set aside for broadcasting. This had made the LTE-B business case harder to prove in for lower streaming demand rates.

This has now changed as Telstra and our partners have enabled the world’s first implementation of the Multicast Operation on Demand (MooD) feature whereby cells in the network only need to configure for LTE-B when there are multiple users watching the same content.

This combined with the Service Continuity feature allows mobile users to move around the network seamlessly between cells configured for LTE-B and those which are not.

Earlier this year we announced our intention to enable LTE-Broadcast (LTE-B) across our entire mobile network in 2018. With MooD and service continuity we are one step closer to that goal as we head into another year of major growth in sporting content demand.

Supported by technology partners Ericsson and Qualcomm, Telstra has now delivered world first capability to ensure LTE-B can be delivered as efficiently as possible.

Service Continuity will allow devices to transition in and out of LTE-B coverage areas without interruption. For instance, you might be at a music festival streaming an event on your phone but need to leave the venue and make your way back home (where LTE-B is not in use). Service Continuity means you can continue to watch the stream and the transition will be seamless – even though you have the left the broadcast area.

Taking that a step further, MooD allows the network to determine how many LTE-B compatible devices in any given area are consuming the same content. MooD then intelligently activates or deactivates LTE-B, ensuring the mobile network is as efficient as possible in that location.

For example, if a die-hard football fan is streaming a match we will likely service that one user with unicast, as that is the most efficient way of delivering the content. However if more users in the same cell decide to watch the match, MooD makes the decision automatically as to whether it is more efficient to service those users by switching the stream to broadcasting instead of individual unicast streams.

With the ever growing demand for data and video, these enhanced LTE-B capabilities will enable Telstra to deliver streaming and data services seamlessly and at scale but continue to provide a greater quality of experience for our customers.

Voice calls still connect us around the world

Telstra News

We are enhancing Telstra’s international voice capabilities offered over our global IP network which carries more than five billion minutes of voice calls, or around 9,500 years of continuous talking, around the world every year. Darrin Webb explains how it will work.

Whilst email, messenger services and social media have transformed the way we all communicate and will continue to do so, the traditional voice call is still a very important way for people and businesses to connect. Special occasions, a quick call to your family or dropping a line to your customers and suppliers – are just a few things you want to be able to do without delay, drop-outs or time lapse. This is especially true during the holidays, when businesses are working to meet the Christmas rush or you’re talking to your loved ones around the world – you want to hear them loud and clear.

Telstra’s global IP network plays a critical role in keeping millions of people – and thousands of businesses – connected with voice calls.

We carry more than five billion minutes of international voice calls every year and see peak volumes over the holiday periods and during critical world events where our network experiences a surge of calls. On Christmas Day alone we handle around 40% more calls compared to an average day of international traffic. Calls are also around 25% longer at this time of year.

We are investing in our network to deliver a superior international voice experience by supporting new voice technologies, such as Voice over Internet Protocol (VoIP) with advanced features, and making sure traditional and new technologies work seamlessly together.

Enhancing our voice experience

To enhance the voice service for Telstra’s consumer and business customers in Australia as well as our international carrier customers, Telstra is in the final stages of  the INVENT (International Next-gen Voice Evolution and Network Transformation) program.

This program will transform our existing global voice network and operational support systems to provide our customers with premiere next-generation voice and multimedia services. It is focused on ensuring we can offer the latest VoIP enabled capabilities, increasing capacity and set ourselves up to support High Definition Voice and Voice over LTE (VoLTE) interworking services.

The network transformation will see a full scale rollout of leading software driven technologies in multiple locations around the world. This will help to enhance our network and ensure there are no delays for International Direct Dialling (IDD), toll-free and roaming services to any part of the world with fewer call drop outs and faster call set up times regardless of whether the call is being made between mobiles, fixed line or VoIP.

In addition to offering a better quality of service, an upgrade to our systems opens up further opportunities for our carriers to swap and trade voice minutes and get better analytics about network performance.

As part of the INVENT program, late last year the new International Convergent Softswitch (ICS) platform in Sydney went live. Partnering with Metaswitch and NetNumber to deploy this solution, this switch carried international traffic between Australia and the United Kingdom, making this critical traffic route the first to benefit from these enhancements just in time for Christmas.

We’re looking forward to rolling these enhances to other key routes in the coming months and migrating more customers onto the new platform.

Leading the way to provide brilliant voice and video calling experiences

Tech and Innovation

Posted on December 9, 2016

4 min read

In 2016, Telstra continued to enhance our mobile network by delivering new technologies focused on providing customers with brilliant voice and video calling experiences.

 

Voice over LTE

Voice over LTE (VoLTE) is the next generation of how voice calls are carried over our mobile network. When calls are made on a VoLTE enabled handset, VoLTE works by integrating the call into the 4G LTE data stream.  Your data will also stay on 4G when you make a VoLTE call which your overall experience will be faster and your calls to other devices that are HD voice enabled on the Telstra mobile network or Telstra’s fixed networks will be in HD.

Telstra launched Australia’s first VoLTE service in September 2015, and soon after we enabled Telstra’s entire LTE footprint with the technology. This means 98% of the Australian population has access to VoLTE from Telstra and we’re currently planning to hit 99% by July 2017.

Our customers are taking advantage of the technology and we’ve seen nearly one million Telstra customers made a VoLTE call in the past month. This figure is on the rise, and we expect to have approximately five million customers using VoLTE by mid-2017.

As of mid-2016, all new 4G smartphones launched to our consumer mobile customers have been VoLTE ready and we expect this to be a core feature for all upcoming post-paid models, with new pre-paid models being progressively supported over time. As always, Telstra conducts comprehensive testing on both the mobile network and the devices we sell to ensure our customers receive the best possible call experience.

With VoLTE now well established, we are rapidly evolving our network and have commenced the roll out of other exciting technologies such as Voice over WiFi and Video over LTE.

 

Voice over WiFi

While most of our customers enjoy great mobile coverage, there can sometimes be spots in homes or businesses (due to location, terrain or building construction) where the mobile network just can’t reach. Others who still live in remote locations just beyond the reach of Telstra’s mobile network want the convenience of using their mobile whilst they are at home.

To help our customers stay connected in even more places in, during October 2016 we launched clever technology called Mobile WiFi calling (also known as Voice over WiFi). It helps make missed calls due to limited in-home coverage a thing of the past and is an Australian first.

Mobile WiFi calling works by handing mobile phone calls between our 4G mobile service and your home WiFi connection. The handover between technologies is seamless so you can walk from room to room or out the front door and continue your call. It means you can now have mobile coverage anywhere you have a solid consumer WiFi service.

It’s available to our Samsung Galaxy S6 and S6 edge customers now and on many more devices soon via a standard over the air firmware upgrade. Customers just need to make sure they have the latest device software loaded and we will look after the rest.

 

Video over LTE

The next generation of video technology for mobile devices – known as Video over LTE or ViLTE – was also launched on our mobile network in October 2016.

ViLTE lets those with eligible devices make video calls to other Telstra ViLTE customers using our 4G and 4GX coverage, the same way you make voice calls today. On ViLTE, the voice and video components of the call are independent, which mean you can turn the video on and off during a call without affecting your voice conversation or you can choose to answer a call as voice only if you do not want to be seen.

What sets ViLTE apart from other video calling offerings is that it also provides a consistent data stream for the video, so it helps to provide a better video quality experience.

ViLTE is currently available to Telstra’s Samsung Galaxy S7 customers, but we’ll be enabling the technology on more devices very soon. In future, we will also extend the capability of ViLTE to allow customers to dial into videoconferencing calls.

 

But there’s more

With these foundational capabilities in the network, we will be able to bring the next generations of messaging to mobile devices and even allow many of these services to communicate directly into handsets, screens and other devices inside the home in future.

Telstra tests its game-changing LTE-Broadcast technology at the NRL Grand Final

Telstra News

Posted on October 4, 2015

This time of year is always an exciting one, but this weekend is particularly nail biting for me.  Hailing from Brisbane, I am already excited about the possibility of the Broncos taking out the NRL Grand Final, but to top it off this year we are also running a trial of LTE-Broadcast (LTE-B) in the Telstra Connected Lounge at ANZ Stadium.

This is another showcase of LTE-B at a major event, following the world first stadium demonstration at the T20 International Cricket Match at the MCG in February 2014, the Spring Racing Carnival in Melbourne in November 2014, and the V8 Supercars at Winton earlier this year. So, in case you’ve forgotten what LTE-B is, put simply it is the future of mobile content and will change the way customers experience live sporting events – or any big events for that matter.

Guests in the Telstra Connected Lounge tonight will be able to access three streams of dedicated content from Channel 9 that will be delivered to a series of LTE-B enabled smartphones through an app, allowing them to browse between live commentary, instant replays and stats of the match as it plays out before them.

Not only does this have the potential to be a game-changing technology to take sporting events to the next level (especially if you’re sitting in the nose bleed section!), it also important from a network perspective as it will allow carriers like Telstra to efficiently manage network traffic.

With demand for mobile data continuing to surge, the network experience can sometimes suffer when tens of thousands of people descend into one place, such as ANZ Stadium, and all try to access the internet at the same time.

LTE-B provides the opportunity to deliver in-demand or popular content using one single stream of data, as opposed to each individual user downloading their own stream of data. This will then free up the network to deal with general use and allow us to continue to deliver a world-class mobile service to our customers.

Stay tuned as more smartphones become LTE-B enabled and enter the market, and we work towards making this capability commercially available in the next six to 12 months.

What sort of content would you want instant access to during a live sporting match or event?

Thanks to our LTE-B partners for helping bring this demonstration to life:

  • Channel Nine (Live Broadcast Footage)
  • Expway (eMBMS Middleware Provider)
  • Intellicore (Application Developer)
  • EVS (Broadcast Video Production – replays & multiple camera angles)
  • Ericsson (eMBMS)
  • Samsung (Devices)

 

What is LTE-B?
LTE-Broadcast (LTE-B) is a new service that allows Telstra to send a single content stream to multiple handsets (i.e. one to many), where previously this required individual content streams to be sent to each individual handset (i.e. one to one).

How does LTE-B enhance my mobile video experience?

This technology enables Telstra and content partners to create and deliver feature rich and HD mobile video experiences more efficiently to our customers and event patrons. For the NRL Grand Final, we are introducing feature rich experiences that provide control for customers, and full HD content, faster than streaming.

When will LTE-B be available for consumers and how much will Telstra charge consumers to use it?

We’re working to make LTE-B technology available for our customers with our existing sports properties, e.g. AFL and NRL content by the start of the 2016 footy season. Pricing and data usage details are still being finalised and will be confirmed closer to commercial launch.

Can LTE-B only be used in stadiums? Where else could customers benefit from LTE-B being rolled out?

Initially Telstra’s LTE-B capabilities will be available on LTE-B capable devices in some 4G areas of the Telstra mobile network. Telstra LTE-B will eventually be available for LTE-B capable devices wherever our customers can access 4G coverage on the Telstra mobile network.

The Next Generation of Voice Calling Starts Today – Telstra VoLTE

Tech and Innovation

Posted on September 16, 2015

4 min read

For most of this year we have been undertaking one of the largest and most complex changes to voice calling in our network for more than 40 years…we hope you didn’t notice!

Starting today, we will be progressively enabling the new 4G Calling capability, Voice over LTE (VoLTE) for Telstra Mobile Post-Paid consumer customers with a compatible mobile handset to use 4G Calling..

VoLTE is the next generation of how voice calls are carried over our network. In those 4G areas where VoLTE has been enabled, when customers make a voice call on a VoLTE enabled handset, the call is integrated into the 4G LTE data stream rather than the previous arrangement of reverting back to 3G.

4G Calling allows customers to maintain a full 4G experience during a call. This means voice and data stay on the same part of the network, therefore delivering faster data access while using the internet as well as super-fast call set up times. So, if you love to walk and talk, or browse the internet and talk, or even email and talk then you’re in for a treat. We think it’s a multi-tasker’s dream! And there is more, we haven’t just enabled HD calling on the wireless network, if you make a call to a Telstra NBN service with a HD handset or to any of our business and enterprise services using HD IP Telephony handsets you will also be talking in full HD.

This is seriously exciting because it’s only the beginning. We can now link the future for voice to the world of multi-media which will enable new and interesting applications and call flexibility, including a path to native voice calling over WiFi (VoWiFi)  allowing a seamless handset experience, video calling over LTE (ViLTE) and even higher definition audio.

On that note, we’ve been at the cutting edge of audio solutions for a few years now and have several mature technologies in the market. Telstra was the first carrier in Australia to offer HD Voice calling to our mobile customers back in June 2011 and we continue to have one of the largest mobile HD Voice footprints globally. In fact in Australia, 70 percent of mobile handsets support HD and over 30 percent of all mobile calls use HD Voice today.

The roll out of VoLTE will be staggered, gradually enabling the full HD capability for different types of calls (ie 4G to 4G, 4G to fixed,4G to 3G etc).Initially post-paid consumer customers will be gradually enabled, and we will later be extending the VoLTE capability to our Business and Enterprise customers, as well as our prepaid customers in the future.

Our main priority throughout the VoLTE rollout is to protect and preserve the superior network experience and world class voice quality that we currently offer to our customers while introducing the benefits of the new 4G Calling service. VoLTE will be available in most parts of our network from the start where there is 3G and 4G coverage available. The brand new iPhone 6s and iPhone 6s Plus will be among the first enabled devices, along with Samsung’s Galaxy Note 5 and Galaxy S6 Edge+ and others including the latest Xperia smartphones from Sony Mobile. To be ready for the switch to 4G Calling, customers with an eligible device must ensure their device software is updated. Some customers may be required to turn on Voice on 4G in their settings as well. Also, devices with Caller Tones or Mobile Protect will not be compatible with VoLTE to begin with. Once VoLTE has been activated customers should experience a seamless transition, with the only give away being the 4G icon remaining on during voice calls.

We are proud to continue to lead the industry by again being the first carrier in Australia to offer this very latest calling technology to our customers with a compatible mobile handset in VoLTE enabled areas and to be included in only a select number of carriers worldwide that are currently offering VoLTE technology to their customers.
