Yet another case of LTE device increases. Accourding to the following article by agaur
The number of LTE user devices announced in the market has more than tripled over the past year and 67 manufacturers have so far announced 417 LTE-enabled user devices, confirmed GSA. The figures include 83 LTE smartphones and 31 tablets. 68 out of 417 devices can operate in the TDD mode.

Old Wine In A New Bottle
The Diameter Signaling Controller – Old Wine in a New Bottle?
Of late there has been quite a bit of talk of the “new world order” and the emergence of the Diameter Signaling Controller (DSC). Is that really the case? For the veterans of the telecommunications industry that saw the progression of control signaling over the past twenty years, this is more like “history repeating itself”. [...]

Voice solutions in LTE
LTE does not have a 'circuit switch core' which means that we cannot have voice calls as it is in 2G and 3G technologies. In the initial LTE deployment cases however, operators are using their legacy networks along with their 4G network for voice services
In a blog by Adnan Basir, he discusses the necesseties for 4G as well as the following available voice solutions are discussed:
Circuit Switched Fall Back (CSFB)
Simultaneous Voice and LTE (SV-LTE)
Voice over LTE (VoLTE)
Voice over LTE via Generic Access (VoLGA)
Over the top (OTT)

The Role of the Diameter Signaling Controller (DSC) in LTE and VoLTE
The evolution of the 2G/3G to 4G LTE mobile data network focuses on high data-rate, low-latency and packet-optimized architecture integrated with multi radio access technologies. At the heart is the all-IP Evolved Packet Core (EPC) and voice-over-LTE (VoLTE) reuses the IP Multimedia Subsystem (IMS). The control plane of the EPC utilizes Diameter as its base and introduces multiple additional interfaces and reuses the IMS interfaces. The standards bodies have largely ignored the carrier grade aspects of Diameter signaling, e.g., scalability, reliability, redundancy and management. This whitepaper describes the role of the Diameter Signaling Controller (DSC) to address these issues while also serving as a natural host for Diameter-based, value-added applications.

LTE growing so fast that even the Smart Phone producers cannot keep up?
In an article by Dan Myer on July 20, 2012 it was released that Ericsson gained a contract with China Mobile for the carrier in Hong Kong where they are to deploy TD-LTE equipment. China Mobile is the world’s largest operator claiming to have more than 683 million subscribers to their name.
According to Myer, Ericsson will be providing TD-LTE equipment in addition to the FDD-LTE equipment they are already providing and will join the two networks by upgrading the existing evolved packet core.
The network will go live later this year and is only being delayed due to the lack of available devices that are able to support both TDD and FDD versions of the LTE standard.
Earlier announcements by China Mobile included plans to deploy more than 20,000 TD-LTE equipped base stations by the end of 2012 and move to 200,000 such cell sites before close of 2013. Also reported is the decision to collaborate with Clearwire, a U.S. wireless operator that is planning to deploy a TDD-LTE network by the start of next year.
So what does Ericsson plan to offer in this effort? They have agreed to provide the following, TD-LTE radio access equipment, network management using its OSS-RC offering, EPC network expansion and upgrade, consulting and systems integration services, and design, training and support services.
This is a great win for Ericsson but until the Smart Phones enabled with the both TDD and FDD versions of the LTE standard are created in the mass numbers needed to cover the area proposed in this venture it will remain on hold.
Once again this is proof of the ever increasing growth in the world of LTE and the need for support in this arena.

No Boom For Mobile Equipment
In support of the previous post by Anjan Ghosal "An Apple a day …. " The following article "No boom for mobile equipment firms in 4G revolution" refers to the iphones drastic growth and effect on the mobile world.

A major headache for operators will be enabling their 3G applications for LTE
Further to signaling traffic management, roaming control, vendor interoperability and legacy interworking, a major headache for operators will be enabling their 3G applications for LTE. There are two approaches to this, either integrate legacy SS7-based services in LTE using Diameter-SS7 interworking or migrate the applications to LTE by “Diameter-enabling” them.
With the introduction of the Diameter Signaling Controller (DSC) as the carrier-grade network element for Diameter in 4G, this provides the ideal point in the network that allows services to be integrated, either hosted or remote and SS7-based or Diameter-based. These applications can monitor Diameter traffic by taking a copy of the Diameter messages and process them, or can work in interrupt mode where the applications can modify the message or respond to them.
In addition to the migration of 3G applications, can a new breed of applications benefit by being hosted on the DSC? With all the Diameter interfaces that pass thru the DSC, there is a wealth of information that can be mined and used for different purposes. The DSC is a unique point in the 4G network to offer value-added applications, both the migration of 3G applications and possibly new applications using policy, charging, subscriber or location information.

An Apple a day ….
On Jun 29, 2012 Apple celebrated the fifth anniversary of the iPhone, a remarkable event indeed. In these few years, the iPhone has generated an astounding $143B (with a “B”) in revenue – more than the GDP of New Zealand! Today, the annual revenue for this single product surpasses that of Coca Cola Company and Microsoft!
But while we raise our glasses to celebrate this veritable milestone, let us not forget to dedicate a moment of silence to mark the obituary of telecom (as we knew it!).
In the late 1990’s, if you chanced to visit CTIA or Mobile World Congress, the biggest booth (and after show parties) belonged to Nortel, Siemens, Lucent, Ericsson, Nokia, Alcatel. All of them falling over each other to woo mobile operators with bulging wallets. Those that did not have a booth ferried the high rollers to their rented mega yachts parked overlooking the bay at Cannes – something that would put Las Vegas to shame.
Well, gone are those days. Nortel is no more. Alcatel and Lucent merged and have never been profitable since. Nokia-Siemens are no different. Ericsson and Huawei are locked in fierce competition with no breakout in sight. And gone are the mega yachts and fancy booths!
The telecom world today belongs to Apple, Google, Facebook and Microsoft (with Skype, Microsoft is the largest telecom operator in the world!). And all this can be traced to the advent of the iPhone.
The iPhone is responsible for morphing the phone from a mere voice communication tool to our window to the world. (From someone who has never owned an iPhone it is quite a compliment!). It has changed how we live life (when is the last time you bought a map, or looked something up in the Yellow Pages?) and spawned a new multi-billion dollar industry around mobile applications. (Apple has since replicated this model with the iPad but let us not even go there!).
It has given rise to new acronyms like – OTT – “Over the Top” – whereby third parties make millions leveraging the mobile networks infrastructure to deliver applications to your device, yet not having to share any of the revenue with them! Net result has been an explosive growth of data traffic on operator networks – yet their inability to monetize that growth.
Technologies like Wi-Fi Data Offload and Long Term Evolution (LTE) are a direct response of the impact of the iPhone (and its ilk). And it is not only impacting the data capacity of the networks, but also the underlying signaling capabilities. Operators and vendors have to adjust to the “new normal”.
