High level view on how SMS works in LTE
The following is from E\\\ whitepaper available here:
In 2010, 6.9 trillion text messages were sent globally and this figure is expected to break the eight trillion mark in 2011. This represents USD 127 billion in revenue for operators. LTE provides the same basic SMS features, such as concatenated SMS, delivery notification and configuration. However, the SMS delivery mechanism is somewhat different. A VoLTE device can send and receive text messages encapsulated within a SIP message. To receive a text message, the encapsulation process is invoked by an IP short-message-gateway in the IMS domain, and the gateway converts traditional Signaling System Number 7 (SS7) Mobile Application Part (MAP) signaling to IP/SIP.
To ensure that text messages are routed via the gateway, the home location register (HLR) of the recipient needs an additional function to return a routable gateway address back to the SMS-C on receipt of an SMS-routing request.
When a VoLTE device sends a text message, it should perform the encapsulation. The gateway extracts the text message inside a SIP MESSAGE signal before passing it on to the SMS-C.
However, if the VoLTE device is configured to not invoke SMS over IP networks, text messages can be sent and received over LTE without the need for any SIP encapsulation. A received text message will reach the mobile switching center server (MSC-S) of the mobile softswitch system in the same way as it does today. The MSC-S will page the device via the SGs interface with the Mobile Management Entity (MME) of the EPC system. Once a paging response is received, the MSC-S will pass the SMS on to the MME, which in turn tunnels it onto the device. Due to the support for SMS delivery and IP connectivity provided by LTE/EPC, MMS works seamlessly.
For more technically minded people, there is a whitepaper that covers SMS in detail available here.

Ericsson Video: Using LTE to broadcast Danish elections
Danes elected a new parliament September 15. As four teams from TV 2 moved between party headquarters, Parliament House and celebration sites, they used standard off-the-shelf LTE terminals to upload interviews to the tv-station, which in turn broadcast the content live to viewers on their channel.
The solution is provided by operator TDC, on the network supplied and managed by Ericsson.

HD Voice - Next step in the evolution of voice communication
Nearly 2 years back I blogged about Orange launching HD Voice via the use of AMR-WB (wideband) codecs. HD voice is already fully developed and standardized technology and has so far been deployed on 32 networks in almost as many countries.
For more information also see:
People who have experienced HD voice say it feels like they are talking to a person in the same room. Operators derive 70 percent of their revenue from voice and voice-related services, and studies show that subscribers appreciate the personal nature of voice communication, saying it offers a familiar and emotional connection to another person.
HD voice is also a reaction to the competition faced by the operators from OTT players like Skype.
Below is an embed from the recent whitepaper by Ericsson:

Benefit of 1.4GHz for Mobile Downlink
Significant benefits could flow from use of 1.4 GHz band for a supplemental mobile downlink for enhanced multi-media and broadband services, according to a study by Plum Consulting conducted for Ericsson and Qualcomm.
The band is currently allocated for use by digital audio broadcasting (DAB) services in most European countries -- part of the band is allocated to terrestrial networks and part is allocated to satellite networks. None of these services have developed in the band. Rather in all countries in Europe the satellite part of the band is unused and this is also the case in the terrestrial component in most countries.
There could be up to eight times as much data being downloaded than is being uploaded in mobile networks. This imbalance is expected to grow, as rich mobile content is increasingly made available and as consumer demand continues to soar. The study found that the use of the 1.4 GHz band as a supplemental downlink band for mobile applications is shown to drastically ease capacity, to enable considerably higher user data rates, to substantially enhance the user experience and to provide significant economic benefits.
The value of releasing the 1.4 GHz band depends on whether other substitute spectrum may become available in the next 5 to 10 years. Starting from today, all countries in Europe have planned or are planning to release the 800 MHz and 2.6 GHz bands in the next two years. There is equipment available for use in both bands and services are already deployed in some countries.
Which other bands might be released over the next 10-15 years? Table 3-2 gives a number of candidate bands, ordered by the likely timing for release, including the 1.4 GHz band for completeness. In each case, we summarise the current status of the band, initiatives that suggest it might be a candidate for future release and our views on the possible timing of deployment based on the difficulty of clearing the band and the harmonisation/standardisation initiatives that would need to be undertaken before equipment would be mass produced for the band.
The white paper is embedded below for reference:

Advanced Telephony Services for LTE
With LTE World Summit just round the corner, I was going through the last year's presentations and realised that we didn't talk of this one before.
The concept for the advanced telephony services has been around since the early days of IMS and this was one of the ways IMS was sold. Unfortunately IMS didn't take off as planned and only now with the standardisation of VoLTE, there is a possibility of the advanced services becoming a reality.
The following presentation summarises some of these advanced telephony services concepts.

More than 50 Billion Connected Devices
I blogged about the 50 Billion connected devices as predicted by Ericsson last year. With the promised 'Internet of things' and 'connected world' we may see 50 billion devices not too far in the near future. Here is a recent whitepaper from Ericsson on this topic.

Making small purchases simpler with Ericsson IPX
Yesterday a colleague made me aware of this Ericsson's IPX SMS based payment system that looks like a competitor to the NFC technology and doesn't involve any additional chip/hardware. Here is a video:
From Ericsson's website:
Ericsson Internet Payment Exchange (IPX) is a leading mobile aggregator, providing delivery and billing services, via SMS, MMS, web and online mobile billing, to more than 2 billion mobile subscribers across 26 countries. Ericsson IPX also brokers location information in selected countries and Ericsson IPX Messaging provides reach to 96% of all mobile subscribers worldwide with SMS. Ericsson IPX customers are companies who offer digital content, mobile voting & directory information and enterprises offering mobile marketing, communities and banking.
Now, we all love SMS and we have to admit that its the simplest of technology and even the most primitive phone nowadays support it but there could be scenarios when this can be a bit of a problem:
1. SMS can sometimes be delayed if a particular cell is overloaded, etc. So how long do we have to stand in front of the machine?
2. If say for 2-3 mins we do not receive an indication that the machine has a cash, do we send another SMS to cancel the transaction?
3. If we have a problem, do we have a support number to call to? How much will that cost?
4. If there is a queue of people and someone else wants to purchase something as well, does the next person has to wait till the person before has received the item?
5. If two people have sent an SMS, how do they know whose cash is in the machine now? Do we start putting a Pin as well ?
I agree, this technology could be really useful if you have run out of cash (even if you have NFC chip) and you need to purchase something small.
The other obvious advantage is that you can target advertisement at regular users who are at a particular place at a particular time to make them buy something. Also you can get statistics like what time people tend to purchase, what do they purchase, where, etc.
Anyway, hard for me to see this take off big time.

IMB and TDtv (and DVB-H)
Its long time since I blogged about TDtv. Its been quite a while since I heard about TDtv. Apparently its been superseded by IMB, aka. Integrated Mobile Broadcast.
IMB is used to stream live video and store popular content on the device for later consumption. This results in a significant offloading of data intensive traffic from existing 3G unicast networks and an improved customer experience. The multimedia client features an intuitive electronic program guide, channel grid and embedded video player for live TV viewing and video recording. All IMB applications can be quickly and cost-effectively adapted to support all major mobile operating systems and different mobile device types, including smartphones, tablets and e-readers.
IMB was defined in the 3GPP release 8 standards, and was recently endorsed by the GSMA as their preferred method for the efficient delivery of broadcast services. In June 2010, O2, Orange and Vodafone – three of the five major UK mobile operators – announced that they have teamed up for a three-month trial that will explore IMB wireless technology within a tranche of 3G TDD spectrum.
This spectrum already forms part of the 3G licenses held by many European mobile operators, but has remained largely unused because of a lack of appropriate technology. Currently, 3G TDD spectrum is available to over 150 operators across 60 countries, covering more than half a billion subscribers. IMB enables spectrally efficient delivery of broadcast services in the TDD spectrum based on techniques that are aligned with existing FDD WCDMA standards. This enables a smooth handover between IMB and existing 3G networks.
Issues that previously limited uptake of IMB, or IPWireless' tdTV system, have now all been addressed. Namely, the standard now allows for smooth handover between IMB and unicast delivery; has the potential to be integrated onto a single W-CDMA chip rather than requiring a separate chip; and has resolved interference issues with FDD W-CDMA, at least for spectrum in the 1900MHz to 1910MHz range.
IP Wireless already had a trial at Orange and T-Mobile in the UK (which have just agreed to merge), but in that pilot each 5MHz segment only gave rise to 14 TV channels per operator. The new standard could support 40 separate TV channels if two operators shared their TDD spectrum.
The GSMA announced its support and is backed up with additional support from both IPWireless and Ericsson as well as operators Orange, Softbank and Telstra.
There have been recently quite a few bad news for DVB-H and on top of that IP Wireless has announced that Samsung is going to be releasing phones with IMB support so it may be that we will see IMB sometime next year.
The GSMA paper that details IMB service scenarios and System requirements is embedded below:
