Local Breakout - A New Challenge for Networks

As LTE rollouts gain pace, consumers will have access to new networks and higher data speed. While it will take time for the end-user market to catch-up with the industry’s perceptions, the industry still needs to address certain expectations around LTE.

 

At first glance the roaming advantages dominate the LTE experience. Local Breakout, a mechanism where roaming traffic doesn’t traverse back to the home network and is handled by the local operator, allows cheaper tariff and will also bring increased localised revenue. The challenge for the network operators is to understand how and where the placement of Local Breakout can be advantageous for them.

 

Networks are only likely to allow Local Breakout if they can either guarantee reciprocal partnerships with other networks or have a larger network than one that simply exists in one country. Networks will need to restructure tariffs to include Local Breakout and it is likely to become a key selling point for operators. While this selling point won’t remain unique for long, it will be the operators that can react fastest with a Local Breakout proposition that stand to gain more.

 

There are still a number of challenges for operators on the use of Local Breakout, beyond working out what they can charge. Guaranteeing Quality of Service will become even more important, especially with a greater use of data and cloud services by consumers. For example, my phone backs up the photos I take with it to my Dropbox. If I took my phone on holiday and it switched to a local network because I have Local Breakout on my contract, I would expect the holiday photos to upload to Dropbox in the same way. If I found that I had lost my phone and all my photos and they weren’t backed-up, due to a poor network, that would cause a customer service issue (to put it lightly)! It also raises the question of who is accountable: the network you were using at the time or the operator with whom you signed the contract that included Local Breakout?

 

Naturally network operators will be keen to avoid such scenarios. They will want to build on a solid infrastructure that will allow connectivity for Local Breakout and other services. The infrastructure change will be provided by IPX. With IPX we gain scalability and flexibility, but also a resetting of the boundaries between providers and networks within the sector. Those able to utilise a larger IPX footprint will naturally have greater opportunity to propagate services. The adoption of the new Diameter standard will be key to the success of IPX implementation and should result in high quality services becoming available throughout the industry.

 

Applying strategic thought to the new roaming challenges provided by Local Breakout, will be key to the success of LTE and networks’ performance in the future. Coupled with the infrastructure demands that need to be met with IPX it will be interesting to see how the networks rise to the challenge.

Michel:  Great overview of local-breakout.  Do you think that we will see any operators starting to offer this in 2013?   Or will it not be until next year when there will be more operators supporting LTE Roaming, before this will be offered to subscribers.

 

Additionally, how will data charges be handled, if the subscriber connects to the Internet through Local Breakout?  Do you think it will be less expensive than today's HSPA (3G) based charges for roaming subscribers?
