Billing based on QoS and QoE

With Spectrum coming at a price the operators are keen to make as much money as possible out of the data packages being provided to the consumers. The operators want to stop users using over the top (OTT) services like Skype thereby losing potential revenue. They also want the users to stop using services that are offered by the operator thereby maximising their revenue.

A valid argument put forward by the operators is that 90% of the bandwidth is used by just 10% of the users. This gives them the reason to look at the packets and restrict the rogue users.

As a result they are now turning to deep packet inspection (DPI) to make sure that the users are not using the services they are being restricted to use. AllOt is one such company offering this service.

The following presentation is from the LTE World Summit:

They also have some interesting Videos on the net that have been embedded below. They give a good idea on the services being offered to the operators.

Finally, a term QoS and QoE always causes confusion. Here is a simple explanation via Dan Warren on twitter:

QoS = call gets established and I can hear what is being said, everything else is QoE

Carrier Aggregation with a difference

Click on picture to enlarge

Another one from the LTE World Summit. This is from a presentation by Ariela Zeira of Interdigital.

What is being proposed is that Carrier Aggregation can use both the licensed as well as unlicensed bands but the signalling should only happen in the licensed band to keep the operator in control.

Note that this is only proposed for Small Cells / Femtocells.

The only concern that I have with this approach is that this may cause interference with the other devices using the same band (especially ISM band). So the WiFi may not work while the LTE device is aggregating this ISM band and the same goes for bluetooth.

Comments welcome!

Dual Radio Solution for Voice in LTE

I did mention in the Twitter conversations post from LTE World Summit 2011 that there are now certain analysts and players in the market who think that it should be possible to have two radios. Here is a slide from ZTE that shows that they are thinking in this direction as well.

Click on the pic to enlarge.

Tri-SIM phones have been available for quite a while but now there are Quad-Sim Shanzhai phones that are available in China. I am sure there is a market for these kind of phones.

With the battery life and the mobile technology improving, these are no longer the concerns when talking about dual radio possibility in the devices. Another common argument is that there may be additional interference due to multiple radios simultaneously receiving/transmitting. I am sure these can be managed without much problem.

Another problem mentioned is we may need multiple SIM cards but the SIM cards used is actually a UICC. There can be multiple SIM applications and IMSI's on it. The network may need some very minor modifications but they should be able to manage this with no problems. In the good old days, we used to have mobiles with built in Fax. The mobile number used to be different from the Fax number. It was a similar kind of problem but managed without problem.

So there may still be time to keep LTE simple by standardising the dual-radio solution rather than having CSFB, VoLTE, SRVCC, VoLGA, etc.

Any thoughts?

LTE World Summit 2011 - Pics and Notes from Day 2

Continuing my notes for the 2nd day of #LTEWS.

Mark Newman from Informa reminded us that there have been lots of hype in the early days of 3G about the revenue, etc. and nowadays he is seeing similar hype about M2M.

CTO of Vodafone Germany, Hartmut Kremling spoke about their their LTE launch that was in Dec. 2010. They launched the LTE in 800MHz band and it has been convenient for them as they are reusing the existing GSM infrastructure.

Since they already support other technologies and spectrum, he was worried initially that LTE 800 was be the 5th network and LTE 2.6GHz will be their 6th network but due to the use of SDR and Integrated antennas in the network that support GSM/UMTS/LTE, they have managed to keep the cost and complexity down.

With LTE, Speed is the killer as the users can get high speed access to their services. Right now they have 20K customers that are using LTE.

They have also launched Easy Box that contains Voice and Integrated services. They have received positive feedback and the download speeds is generally 5-6 Mbps.

Yegor Ivanov of Yota, Russia spoke about how they moved their existing infrastructure from WiMAX to LTE. They already have 1million+ customers on their WiMAX network.

Yota is going to build a shared infrastructure for all the big 4 russian network operators. He is expecting to have 70 million people covered by 2016. Right now the LTE revenues are 4 times lower than their existing 3G revenues.x

Finally, Andrea Folgueiras from Telefonica Germany had an interesting presentation and sense of humour. When she started her presentation she mentioned that she has been with them for 20 years. So as to not give her age, she said she started with them when she was 10 :)

Telefonica believes in LTE for best mobile and data experience. They have 800MHz which would be used for national rollout and also 2.6GHz that would be used for dense areas. They will prioritise the services based on different QoS.

Finally they think that the paradigm has changed from 'Always on' to 'Always in touch'

There is more information available on the twitter conversations.
