Mobile Virtual Network Operators (MVNO) New Generation Network (NGN) Long Term Evolution (LTE) IP Multimedia System (IMS)

Emerging Technologies

A cellular telephone system links mobile station (MS) subscribers into the public telephone system or to another cellular system’s MS subscriber.

GSM networks are made up of Mobile services Switching Centres (MSC), Base Station Systems (BSS)and Mobile Stations (MS).

The cells are normally represented by a hexagon, but in practice they are irregular in shape. This is as a result of the influence of the surrounding terrain, or of design by the network planners

The two main types of operators are: mobile network operators (MNOs) Ex: Nokia Siemens Networks mobile service operators (MSOs) Ex: Vodafone

Recently a new business concept called MVNO has emerged.

Mobile Virtual Network Operators was introduced first in Europe with an intention to bring the cost of calling /data service by increasing competition in market.

SIM-based mobile services without the network or rights to the required radio spectrum.

MVNOs can be described as a subgroup of MSOs. The radio capacity used to provide these services is

gained through commercial agreements with licensed mobile network operators.

MVNOs deliver their own SIM cards and take care of the branding, marketing, billing and customer care.

The simplified business objective would be to maximize the profit of the total business, i.e.

Profit = ARPU * Customers – Cost

MVNO

Business strategy scenarios: low price Narrow focus: a cell phone user may be able to subscribe to a

network operator plus multiple MVNOs for specific data services over the same phone. One MVNO could provide sports news, another weather and traffic

Service differentiation: providing value added service to . demanding customers like organisations which need both landline aswell as mobile service.

Service reselling: MVNO with strong technology competences but low brand value can select to become a reseller and enabler for other MVNOs already having a strong brand

International clustering: Global and regional MNOs can select to enter a new country as a MVNO instead of investing

in or acquiring a local MNO

Next big thing to happen in telecom.

It is a packet-based network which can provide services including Telecommunication Services and able to make use of multiple broadband.

For voice applications one of the most important devices in NGN is a Softswitch – a programmable device that controls Voice over IP (VoIP) calls. It enables correct integration of different protocols within NGN

Use of intelligent networks to send both data and voice as packets through common data channel.

Just like VOIP, but today its implemented only by specific organizations for their specific use.

Imagine telecom Giant like BSNL implementing VOIP throughout the country –that is NGN

New Generation Network

It is a dominant mobile data technology for the next decade.

It is a radio platform technology that will allow operators to achieve even higher peak throughputs than HSPA+ in higher spectrum bandwidth.

LTE is part of the GSM evolutionary path for mobile broadband, following EDGE, UMTS, HSPA (HSDPA & HSUPA combined) and HSPA Evolution (HSPA+).  

The first commercial LTE networks were launched by TeliaSonera in Norway and Sweden in December 2009.

LTE capabilities include Downlink peak data rates up to 326 Mbps & Uplink peak data rates up to 86.4 Mbps with 20 MHz bandwidth

Long Term Evolution (LTE)

LTE provides an extremely high performance radio-access technology that offers full vehicular speed mobility and that can readily coexist with HSPA and earlier networks. Because of scalable bandwidth, operators will be able to easily migrate their networks and users from HSPA to LTE over time.

LTE assumes a full Internet Protocol (IP) network architecture and is designed to support voice in the packet domain.

It incorporates top-of-the-line radio techniques to achieve performance levels beyond what will be practical with CDMA approaches, particularly in larger channel bandwidths.

LTE systems will coexist with 3G and 2G systems. Multimode devices will function across LTE/3G or even LTE/3G/2G, depending on market circumstances.

It is a generic architecture for offering multimedia and voice over IP services, defined by 3rd Generation Partnership Project (3GPP).

IMS is access independent as it supports multiple access types including GSM, WCDMA, CDMA 2000, WLAN, Wireline broadband and other packet data applications.

IMS will make Internet technologies, such as web browsing, e-mail, instant messaging and video conferencing available to everyone from any location.

It allow operators to introduce new services, such as web browsing, WAP and MMS, at the top level of their packet-switched networks

IP Multimedia Subsystem (IMS)

Capabilities and Benefits

IMS provides a flexible IP media management and session control platform that operators can layer over their current network infrastructure.

IMS allows operators to leverage long-term value of existing network equipment, reducing the capital investment associated with new service development and deployment.

Access to network services can be secured through a web-friendly interface, enabling third-party developers, service providers and even subscribers to self-manage their service experience.

Simplified, secure access for all parties means fewer network staff resources are needed to manage new services, which in turn reduces delivery and operations costs and offers higher pricing flexibility.

Subscribers can control when and how they communicate. They can choose the most appropriate medium or combination of media—video, voice, text, images, or instant messages—all available simultaneously and in real time.

Over the IP backbone, operators can quickly bring new services to market, targeting new segments to attract new revenue streams.

Services through the IMS Solution

Presence services Full Duplex Video Telephony Instant messaging Unified messaging Multimedia advertising Multiparty gaming Videostreaming Web/Audio/Video Conferencing Push-to services, such as push-to-talk, push-to-

view, push-to-video

Motorola IMS Solution

A Telecom Industry Case Study

NOKIA SIEMENS NETWORKS

It promises to ease telecom network congestion and possibly change the market for such equipment for good.

It shares network resources across mobile and broadband networks, similar to cloud computing.

It is a solace for telecom operators around the world who are struggling with a shortage of network capacity as the use of video on smartphones and tablets proliferates.

Liquid Technology.

Self-aware, self-adapting: The network needs to be always aware of the user demand, service

needs and its current operational state.

Software-defined applications on multi-purpose hardware: Network applications, mainly hardware independent, defined by

software and highly configurable, running on multi-purpose platforms, achieve flexible capacity across the network.

Inter-linked architecture: Liquid Net features a much more inter-linked architecture that allows

capacity and processing to flow freely across the network.

Investment-protection, evolution: Innovation often comes at a price – the need to replace existing

infrastructure with new equipment, wasting previous investments.

Four key enablers to making networks more fluid:

Liquid Radio: Redefining base station-based architecture

It self-adapts its capacity and coverage to match fluctuating user demand. Through baseband pooling, it redefines the conventional structure of base stations and repositions their components in new ways to achieve unprecedented scalability.

It also offers Heterogeneous Networks, which enable all network layers to be used as a logically unified network.

Another aspect of Liquid Radio is Active Antenna System technology, which supports multiradio and multi-band access for GSM, 3G, LTE and LTE-Advanced, providing up to 65% capacity gain.

Liquid Core: The foundation of the broadband experience

Fluidity in the core network (IMS functions) smartly tailors and delivers services and content, and dynamically provides the capacity needed to ensure the best customer experience at the lowest cost.

Intelligent Broadband Management allows a network that is aware of, and can adapt to, user demands to deliver the best customer experience at the lowest cost.

Liquid Net: Tapping into the future ofbroadband

Liquid Transport: Free-flowing traffic across network layers

The transport infrastructure implements fluidity to ensure services can be delivered to all possible clients simply and quickly, while keeping costs as low as possible.

Liquid Transport achieves more flexibility and scalability by making the optical transport layer, the lowest layer with the least Total Cost of Ownership (TCO), more software configurable.

It also introduces a multi-layer intelligent control plane to enable flexible, rapid and easy network operation and service provisioning.
