LTE needs IPX to be a truly global success. When domestic LTE deployments are supported by global IPX-enabled networks, it changes what is possible in the mobile market. Today, we’ve seen the development of LTE networks on a local level but for 4G services to mature and realise their full potential LTE needs to be supported with robust, reliable and intelligent IPX-enabled networks.

There will be 450 commercial LTE networks deployed by the end of 2015, according to The Global Mobile Suppliers Association (GSA). Close to 50% of subscribers in Q4 2014 were in Asia-Pacific with North America and Europe trailing close behind.

Voice over LTE (VoLTE) is considered by many to be a revolutionary application, for both mobile operators and their subscribers:  Operators, once they establish VoLTE networks, will no longer have to maintain separate networks—circuit-switched for voice and packet-switched for data. As a result, they will see savings in both operational and capital expenses.  Subscribers who use VoLTE will be able to use high quality voice and data applications simultaneously, while enjoying greater clarity in voice calls.

However, VoLTE deployment has been slower than anticipated due to several challenges…

This post is by Malcolm Chan, Managing Director, BICS, Asia-Pacific.

Asia is expected to account for almost half (forty-seven per cent) of all LTE connections by 2017, as LTE networks are rolled out in major markets such as China and India, making Asia-Pacific the world’s largest LTE market in terms of service revenue. In the face of this tremendous growth, operators need to seek innovation through Next Generation Communication Services to maintain market share and customer loyalty.

To achieve this, operators need to ensure they provide an enhanced user experience. Central to this is an enriched communication experience with IMS based services like VoLTE and Rich Communications Services (RCS).

As OTT players increase the number of VoIP and messaging services they offer their customers globally, mobile operators need to deploy VoLTE and RCS services in order to offer innovative high quality services through their unique proposition of ubiquity, global reach, quality and privacy management.

Interview: International Product Manager for Mobile Solutions, A1 Telekom Austria: “[The customer experience] is significantly improved when the customer’s MNO is served by an IPX provider that can offer guaranteed QoS.”

Roman WaditschatkaRoman Waditschatka, International Product Manager for Mobile Solutions, A1 Telekom Austria is speaking on the topic of “Creating a consistent customer experience when roaming,” taking place on Day Two of the 9th annual LTE Asia conference, taking place on the 23rd-25th September 2014 at the Marina Bay Sands, Singapore. Here he gives us his views on why IPX is so important for the modern network operator.

LTE roaming is starting to become a reality – what are the main challenges to making it happen?

The main challenge is having a reliable IPX provider with a flexible core network infrastructure to interconnect MNOs that can tailor itself to their needs. Telekom Austria Group’s global IPX network guarantees our customers global LTE roaming coverage by exchanging traffic with their roaming partner networks worldwide.

To what extent does having a wholesale business with knowledge of signalling issues help solve roaming challenges?

The pain of living without 4G

Mobile World Congress may have ended a month ago but am only now getting ‘closure’ on the event. The reason – I’ve just been reunited with my iPhone that I thought had been stolen at the event. What happened, in case you were interested, is that I had placed my iPhone in one of the many charging lockers around the venue only to find that it wasn’t there when I returned. I couldn’t believe it. The locker was locked when I left it – but when I returned, to my amazement the phone wasn’t there.

A search using the ‘Find My iPhone’ feature did not help – as I had put the device in ‘Airplane mode’ before placing it in the locker in order for it to charge quicker. (A handy tip for you there – as long as you don’t need to try and locate your phone shortly after).

The incident rather put a damper of the show and I returned home rather forlornly.

Happy days then when I got an email from staff at the venue saying that my phone had been found! While I was pleased, I was very confused by what had happened. Where had it gone? Had I done something stupid and simply looked in the wrong locker? As such, I decided I would keep it to myself and not tell anyone what happened. Apart from my colleagues. And my friends. And family. And this blog post.

After two weeks of some frustrating failed courier pickups later the phone was sent back to me safe and sound by regular post. 

What came of the experience is that for nearly three weeks I had to borrow a phone, kindly lent to me by a friend. It was a two-year old HTC One X. This was noteworthy as it would be the first time that I would be using an Android phone for any length of time since I reviewed the second Android phone ever released, in a previous job.

In those days Android and the iPhone were still light-years apart – can you believe that there was no multi-touch on Android, but these days it’s Android that’s ahead in terms of feature.

Initial impressions using the phone were good. Compared to last time I used it there’s an Android app for nearly everything – though my favourite iOS Podcast app Downcast isn’t there and the interface for BeyondPod, the Android equivalent had me scratching my head somewhat.

But widgets! That’s a feature that I really enjoyed that isn’t present in iOS. You can place a small version of your app on the phone ‘desktop’ – so you can, for example, play or pause a podcast with one tap, or see live train timetable information, without having to launch the app, and then search within in it. It’s great.

However, once past the widgets the experience soon palled. The phone felt very plastickly, apps were slow to respond, while the touch screen seem oversensitive.

The biggest issue though, was network speed. This was a 3G phone, and while I expected things to be less speedy compared to 4G I was surprised by how unresponsive everything felt. As Joni Mitchell once sang that: “you don’t know what you’ve got till it’s gone.”

What once seemed easy – checking Facebook or Twitter, downloading a podcast, or just reading a web page now was an almost painful experience. Apps didn’t seem to respond, and the spinning download circle was permanently on screen, either when checking web pages or waiting for the bike hire app to update with some useful information.

Speed tests revealed that despite the ‘H’ insisting I was in an HSDPA area most of the time I was getting less than half a meg of speed. Combined with the high latency inherent in 3G it all made for a frankly poor experience. Rubbish.

However all was finally restored to normal yesterday when I finally was reunited with my iPhone. It was something of process getting it back to working order – charging it up, backing it up, watching it automatically erase when it went online, restoring it from a backup, and then physically cutting down my replacement combi-SIM to an iPhone 5 friendly nano SIM – with all the attendant will it work drama that this entails. That was a fun evening.

Now I have it back to working order, it really struck home that 4G really does enable smartphones to live up to their billing as smart devices and I really appreciated being able to do the things I had taken for granted.

I’m now back at my desk streaming hi-res FLAC music files from my NAS box at home, something that would be completely impossible with standard 3G. But while that might be an extreme use, even for more conventional use 3G simply doesn’t cut it. Yes you can use smartphones at speed on Wi-Fi, but real mobility and freedom comes from being able to able to use the power in your device when and wherever you are.

4G then is now no longer to my mind a next-gen technology– it simply enables you to use your phone as it should be.

Now, where my 5G?

While IPX is a technology that has been on many operator’s agendas since 2012, it was 2013 that really shaped up to be a dynamic year for those in the IPX realm. Last year saw increased interest in this technology, with many global service providers, including Deutsche Telekom, Orange, Telecom Italia, Telefónica, TeliaSonera, and Vodafone reporting pilots for voice-over-IPX.

Now 2014 is looking as if it will be even more significant and with LTE is being heralded as the key driver for IPX, discussions surrounding this technology are increasingly filling up our news feeds and dominating roaming and voice debates during LTE events. With the threat of OTTs looming and the need for operators to gain ROI from their LTE investments, MNOs are now looking at new ways to stay ahead of the game in an increasingly competitive market.

Kevin M. Kleinsmith, Director of Engineering, Union Wireless (USA) is speaking on the subjects of VoLTE and backhaul at the LTE North America conference, taking place on the 21st-22nd November 2013, in Dallas, Texas, USA. Ahead of the show we speak to him about the details of what is required to implement VoLTE on a network.

Is there any difference between the challenges of VoLTE roaming within the US, and roaming internationally?

There are several key differences in domestic roaming and international roaming. The biggest challenges come from the way the VoLTE call would be handled by a local breakout or would it have to go all the way back to the home network. Breaking it out as local as possible would be ideal, however, now we have to change the way the billing is currently handled. The GSMA-NA groups related to this, such as IREG and BARG, are trying to resolve the best practices, but until the industry agrees on a practice, a lot of smaller companies are simply going to have to rely on their major partners or third-party vendors on the proper solutions given their specific relationships.
