How Wi-Fi Service Providers are Profiting from the Mobile Data Capacity Crunch
Wi-Fi services are now being welcomed by the cellular industry, and every mobile network operator today has to plan for a comprehensive Wi-Fi strategy. As a result of the phenomenal growth of smart phones and data applications, the spurt in data usage is causing capacity bottlenecks for mobile network operators. The quickest and least expensive path to solving these bottlenecks is by offloading data traffic from the mobile network to Wi-Fi hot spots. Now Wi-Fi service providers have even more to offer mobile network operators.
Diameter Proxy and Relay Agents in Next Generation LTE and EPC
With industry forecasts calling for as much as a hundred fold increase in data traffic over the next five years, operators face many challenges in scaling their networks in a cost-effective manner. With the increasing importance and reliance on the IP network infrastructure, most of the traffic will be routed over IP transports over different PMN’s. There is a need for edge routers and gateways that route messages appropriately to the end destinations. There is also a need for edge devices to do access and policy control right at the edge rather than at the HPMN so as to avoid multiple packet hops and maintain and improve the efficiency of the services delivered. Learn about the Diameter proxy and relay agents that provide these services.
Mobile Data Offload - Can Wi-Fi Deliver?
Mobile Network Operators have long recognized Wi-Fi as a potential means of adding wireless capacity by leveraging low-cost access points and free spectrum. However, the Wi-Fi solution has been elusive. The exponential growth of data consumption, by today’s army of smart phone and intelligent wireless device users, has become a game changer forcing carriers re-look at Wi-Fi as an alternative access mechanism. Are things going to be different this time around? Or will Wi-Fi access again be relegated as a niche technology without mass appeal? In the third part of the series, IntelliNet Technologies' CEO, Anjan Ghosal, looks at Wi-Fi as a disruptive game changer and offers his views on the controversial subject.
The Business Case for Mobile Data Offload
Does the traditional strategy of continually adding network capacity suffice to meet the growing demand of smartphone data? Does it make business sense to seek an alternate path of delivery to the user? In the second part of our series, IntelliNet Technologies outlines the business case for mobile data offload. With inputs from Neu-Mobile, the business case highlights the economics to solve the growing demand on the data network and the benefits of offloading to the increasingly ubiquitous Wi-Fi technology.

The tsunami of data over the wireless networks has created significant problems for network operators. In this paper, Arun Handa, CTO of IntelliNet, details the growth of data usage on mobile networks and its impact on network operators. He then explains the solutions available to mobile network operators and describes the merits of each. Data offload and specific offload solutions are then explored in depth.
SS7 Over IP Signalling Gateway
Implementing platform independent applications have always been on most developer's wish list. The emergence of a new range of telephony platforms has pushed that to the forefront. Porting to a new platform is not simply moving to a new operating system. It includes duplicating the entire environment and all application interfaces on the new platform. This paper follows the progress of SS7 applications over the years and reviews a generic architecture of an SS7 application. It identifies a core state machine and five interfaces - SS7, Database, Switch control, Management and 3rd party IPC. The paper outlines development techniques that can be used to ensure that porting SS7 applications and all the interfaces can be achieved at minimum effort. A number of SS7 stacks are reviewed. Comparisons are made with the platform independent AcceleroTM suite of products including advantages of one approach over another. Finally, it looks at the emergence of SS7oIP and the requirement for transport independent applications that can seamlessly operate in both the SS7 and IP networks.
Fixed Mobile Convergence
Fixed Mobile Convergence (FMC) solutions are promising to deliver the long-awaited hand-off of calls and calling features between wireless and wireline networks. Wireless, wireline and cable network providers can provide services to users irrespective of their location, access technology and terminal. Today, several solution approaches are being tested and various business models are emerging. Our FMC White Paper will review these approaches [Session Initiation Protocol (SIP) based architecture, Unlicensed Mobile Access (UMA) and the much touted IP Multimedia Subsystem (IMS)] and offer an in-depth look into reality of Fixed Mobile Convergence.
Intelligent Convergence - Beyond Packaged Translation
Heterogeneous Networks are proliferating with the growth of disruptive communications technologies. While this brings gamut of richer services for the user and better opex/capex opportunities for the service providers, the challenge to bridge the new worlds with an existing large user installed base still remains paramount. IntelliNet's "Beyond Packaged Translation" White Paper, we will examine the complexity of bridging networks intelligently and seamlessly and how applications can be used to provide a flexible architecture to enable this convergence.
The 3GPP IP-Multimedia Subsystem (IMS)
Building Value with Next Generation Services and Applications For those who waited too long for 3G to roll out have had to contend with skepticism and adopting interim disruptive technologies. With the return in the industry momentum after the downturn and excitement generated from multimedia and Internet technologies, operators are planning for their IMS rollouts within the next 12-18 months. In this brief, we explore how real is IMS and how IntelliNet can help you get there.
Beyond SIP - DIAMETER
There is no question that SIP, with its deployment in VoIP networks on the control plane and its rich set of multimedia supporting features, is becoming accepted as the backbone of future networks based on IMS. But is it adequate for future IMS services? This paper explains why service providers need DIAMETER to exercise control of the usage of IMS services.
Importance of True Interoperability if IMS is to be Deployed by 2007
Fixed Mobile Convergence (FMC) solutions are promising to deliver the long-awaited hand-off of calls and calling features between wireless and wireline networks. Wireless, wireline and cable network providers can provide services to users irrespective of their location, access technology and terminal. Today, several solution approaches are being tested and various business models are emerging. Our FMC White Paper will review these approaches [Session Initiation Protocol (SIP) based architecture, Unlicensed Mobile Access (UMA) and the much touted IP Multimedia Subsystem (IMS)] and offer an in-depth look into reality of Fixed Mobile Convergence.
Unraveling SCIM
Implementing a solution drawn from standards based specifications often exposes some gaps that are left to the creativity of the implementers. In the IMS Reference Architecture the Application Server may contain "Service Capability Interaction Manager" (SCIM) functionality. The SCIM functionality is an application which performs the role of interaction management. This paper explores where SCIM comes into play and how we can expect it to be implemented.
Rapid IMS Development Using Highly Redundant Telecom Middleware
The IP Multimedia Subsystem (IMS) is the hottest buzzword in the telecommunication industry today. IMS is a reference architecture standardized by the 3rd Generation Partnership Project. IMS defines a unified IP based network for voice, data and video and offers a variety of services. 3GPP IMS defines an architecture that enables IP based services to IMS enabled User Equipment (UE) through any connectivity access network.
Convergence in Cable TV Networks
The action in the cable industry is as exciting as the programming it delivers. There are bunch of new events on the horizon and everyone is waiting for their prime time. Convergence stands out as the most sought after slot. Convergence - enabled either at the network, service or device level - appears to the consumer in the form of bundled services. This bundling is fairly attractive to the service provider for increased ARPU, customer satisfaction and lowered churn. The cable Multiple System Operators (MSOs) have demonstrated this very effectively by leveraging broadband and now VoIP from what was originally just video services. Cable MSOs today have about a 50% share of the VoIP broadband market, which is an impressive feat.

Sorting Out FMC, UMA and VCC
The telephony alphabet soup can be daunting and sometimes even humorous. What started out as Fixed Mobile Convergence (FMC) gave way to specific implementations with new nomenclature followed by standards bodies that added their own twist. Then IMS comes along with something called Voice Call Continuity that deals with much more than just voice. This paper will attempt to sort out the jargon and, more importantly, compare the technologies and take a look at what is happening in the real world.
IMS-Lite: Small Can Be Beautiful Too
Most of the ink devoted to IMS addresses large scale opportunities. Development activity is being driven by the needs of very large Tier 1 carriers with a focus on converging the fixed and wireless networks they own as well as converging the applications that drive revenue growth. But is there a need for smaller implementations of IMS...
The IMS Policy Function and PCRF

The policy function is the key to making this functionality possible and is directly responsible for the QoS perceived by the consumer...
Why Not Open Source?
Once you have designed the architecture for your IMS network element or application, if it includes subscription, policy or charging, then you need the AAA functionality of the Diameter protocol stack. Now you are faced with a fork in the road. Do you go with open source Diameter that can be downloaded at no cost or do you invest in one of the supported implementations?
