VoLTE has evolved significantly from a year ago. At the event last year many operators were planning their VoLTE roll-out and engaging their technology partners such as Viavi on the challenges to address and ensure they deliver on the high expectations of VoLTE. Now, we have many operators who have either deployed or are very close to deploying. Of course now that LTE is much more broadly rolled out, this sets the foundation for extra LTE-based services such as VoLTE.

There is also the area of the relevance of voice today – many people have an iPhone or other Smartphone and use a multitude of methods to communicate – certain generations don’t talk at all! So, the industry has had to appreciate that VoLTE needs to be integrated into the way people communicate today.

Landscaping QoE in a new mobile world

Today, Mobile Service Providers find themselves struggling to cope with the increasing demand for capacity whilst maintaining a high level of customer experience. Trying to find the most flexible and cost-effective infrastructure to support next generation services whilst also attempting to reduce customer churn by providing adequate customer level Quality of Experience (QoE) & Quality of Service (QoS) can be difficult to achieve. Essentially, Service Providers are caught between a rock and a hard place.

Subscriber level QoE is a subjective matter that is a balancing act; there are a number of factors which need to be considered:

  • Localised low signal quality
  • Numbers of connections using the network in a particular area
  • The performance of a particular mobile handset
  • Download bitrate
  • Resolution and encoding of video content
  • Responsiveness of mobile or web based applications
  • User service plans

Professional testing is key in ensuring high QoE for VoLTE

This guest blog post was written by Kai Ojala, CTO, Anite Network Testing

The requirement for VoLTE is to offer high-quality voice calls and video calls, which as a baseline requires wide LTE coverage. LTE networks fulfill this aspect – especially lower carrier frequencies are deployed globally (e.g. 700 and 800 MHz frequency bands). Operators will benefit from customers switching to VoLTE services by harmonizing voice services and getting better capacity out of the spectrum.
Voice calls in LTE networks can be handled using Circuit Switched Fallback (CSFB) and Voice over LTE (VoLTE). CSFB provides a mechanism to transfer an initiated voice call to legacy circuit-switched networks. VoLTE, on the other hand, is a fully packet switched technology which uses Voice over IP (VoIP) technologies. With the SR-VCC functionality voice calls made with VoLTE can be switched over to legacy networks when the user moves out of the LTE network coverage.

Interview: VP & GM Service Provider Platforms, Cloud Networking, Citrix: “The defining challenge for LTE will be ensuring QoE is maintained at all times.”

Following the successful LTE Awards 2013, we speak to Chris Koopmans, VP & GM Service Provider Platforms, Cloud Networking for Citrix, winners of the ‘Best LTE Traffic Management Product’ category.

Tell us more about your entry to the LTE Awards 2013.

Citrix ByteMobile entered the T3100 into the Best LTE Traffic Management Product category for the LTE Awards 2013. LTE promises a better user experience to subscribers, from superfast web browsing to stall-free HD video. For the operator, this means the opportunity to deliver new mobile services, generating extra revenue from content such as premium streaming movies, TV, music and video calls. However, the move to LTE does not in and of itself guarantee a good user quality of experience for all of these services all of the time. All too often, the very services that delight us can severely hamper network performance, degrading the experience for many – and immediately breaking the operator’s promise to the subscriber.

Monetising OTT traffic on LTE networks

With the roll out of LTE networks around the world, mobile data usage is skyrocketing, opening the door to a wealth of new revenue opportunities for communications service providers. However, at the same time, operators are being challenged to find ways monetise LTE services beyond basic access fees, while maintaining a high quality of experience (QoE) for subscribers.

Today, most LTE pricing schemes are based primarily on speed and the number of gigabytes consumed. However, as LTE moves towards the mainstream, operators will be forced to introduce new service differentiators in order to remain competitive and increase LTE revenues. That being said, in the not too distant future, emphasis on LTE speed will be replaced with the introduction of more personalised LTE “experiences”, including unique value-added services.

With the growing popularity of over-the-top (OTT) players like Facebook, Skype and Netflix on LTE networks, operators who properly leverage OTT traffic intelligence today stand to benefit greatly in the long run.

Unlike 3G, where traffic detection (or deep packet inspection – DPI) was an important tool to help manage network traffic and reduce congestion, the 3GPP forum has defined traffic detection as an integral function for LTE networks. A feature of the 3GPP Release 11 LTE standard, “Traffic Detection Function” (TDF) enables operators to view critical data across their networks and obtain actionable subscriber insight.

By enabling operators to easily identify the subscriber, the application, and content in use, as well as the device, TDF enables carriers to create personalised application-based service tiers and offerings that uniquely match subscriber preferences. Such packages can include tailored gaming, social networking, video streaming and other services.

This network visibility provides greater flexibility when it comes to managing quality of service, charging for use, and steering traffic to value-added services. Moreover, the introduction of new personalised pricing plans deeply appeals to subscribers, helping to generate new revenue, increase QoE and reduce churn.

In addition to introducing new pricing plans, TDF enables operators to create device-based service offerings. For example, operators can identify mobile tethering and apply a premium charging plan. Additionally, TDF lets operators enhance the quality of service for applications like VoIP or video streaming, and then charge more for premium experiences. Finally, TDF enables carriers to easily migrate from 3G to 4G LTE, while keeping policies, speed, and quality of service consistent.

In today’s competitive market, it is clear that DPI technologies, which are at the core of TDF, are no longer a ‘nice feature to have’; they are essential tools to both enhance the service provider’s business and enrich subscriber experience. Those operators that invest in understanding OTT traffic patterns and are able to successfully translate the data into new, personalised and differentiated service plans, will enjoy a competitive advantage, while reaping the benefits of optimised network performance and new revenue streams.
