The impact of IPX – past, future and present

3 years ago

intro medium

In the most recent ROCCO report about IPX, Telia Carrier was mentioned as one of the five leading IPX carriers in the world. What made us even more proud was that it wasn’t us claiming this, it was feedback from our customers – the most valuable feedback you can get as a company. And it does strengthen our belief in our mission to provide exceptional network infrastructure and services – empowering individuals, businesses and societies to execute their most critical activities.

IPX keeps reminding me of this Beatles song (for our younger readers, quite a famous boy band back in the 60’s) “It was 20 years ago today, Sgt. Pepper taught the band to play”. You could replace “Sgt. Pepper” with Telia Carrier and ok, it wasn’t exactly 20 years ago, but we have been one of the main drivers behind the roll out of IPX and the enablement of different service layers on top of the IPX network.

We have a set of principles we live by, where “Challenge Everything” lies at the core of who we are. This means constantly looking for new ways to push the boundaries in order to raise the bar in the carrier industry. Subsequently we were one of the first carriers to realize that the GRX network wasn’t capable of supporting the next generation needs of our customers. Hence we started building our dedicated IPX network in 2012 and launching a QoS enabled network, covering 200 PoP’s from day one.

Soon after that, we started migrating our Mobile Data customers towards the IPX network, and were one of the first carriers to support Diameter signaling. Since then, new services are being added continuously, with VoIPX and IoT backhaul being the latest. And IPX has certainly proven its resilience this past summer. In Europe we saw the roaming traffic triple and now with the fear of bill shock being removed from end customers, we anticipate an even higher usage next year.

Yet it doesn’t stop here. The next challenge will be around IMS. The main objective from an IPX carrier perspective would be to provide seamless interoperability between IMS and non IMS networks. This would not only require the deployment of several IMS functional blocks in the IPX domain of the Carrier but will also lead to some tough choices in business models. We are well underway in executing our strategy of becoming a next generation Telco. Part of this plan is the migration to an “IP only” strategy for all of our voice traffic, phasing out all of our TDM infrastructure. With our latest VoIP technology and our continuous efforts in the IPX domain we are in a prime position to assist our customers in supporting seamless IMS roaming and interworking.

 At Telia Carrier we have a saying: We can’t predict the future, but we can be ready. Although looking at a quote from one of the 120 MNOs interviewed in the ROCCO report mentioned above, our customers seem to disagree. Because they say: “They (Telia Carrier) predict what we need and deliver before we ask”.

And we can’t really ask for more than that.
