The "Flattening Effect" and Network Intelligence
|
|
Because the network has simultaneously become both flatter and more complex, the journey toward a converged all-IP network comes with an entirely new set of network performance and management philosophies to be adopted and developed by IT organizations. To drive the need for maintaining and managing the experience of the subscriber, real-time monitoring, troubleshooting and provisioning of the network must be implemented strategically and methodically. Real-time monitoring of network traffic has proven to be crucial to diagnosing and analyzing network performance and services, and consequently the subscriber’s quality of experience (QoE).

Safe SIP Trunking: New Security Requirements for Enterprise Adoption of SIP-based Services and Applications
|
|
As more and more
applications and devices become SIP enabled --from deskphones to smartphones to
tablets to softclients on any device – the move to SIP trunks promises to
simplify the entire communications infrastructure for the typical enterprise
adopter, centering on SIP as the common denominator across internal and
external communication. Howeve, have you ever heard of vishing? Here we consider security implications.

Setting the Record Straight on Location Tracking and Privacy
|
|
A so-called 'location-gate' controversy has raged over the revelation that Apple and Google tracked mobile subscriber location movements and stored that information in an unencrypted file on the handset that was potentially vulnerable to hacking and other attacks. The discussion should be refocused on how location and other sensitive information is protected, what it is used for, and the responsibility consumers have to make sure they understand how and why their location information is being recorded.

Reducing 4G/LTE Testing Time with Trial Acceleration
|
|
LTE trials usually involve a lot of repetitive cabling / un-cabling and configuration of both the test network and the device under test itself. A new method, called Trial Acceleration, helps service providers to get through the evaluation phase and to market faster, and it allows much more control when working with existing products and new software loads.

Solving the Mobile Video Puzzle on Today's Networks
|
|
An important piece of the mobile video puzzle throughout most of the world is the Third Generation Partnership Project’s (3GPP) 3G-324M protocol. While it does not yet apply to the U.S., most mobile service providers who understand the inherent challenges of deploying low-latency video applications with high service quality in a 3G network realize that it is important to focus on solutions that incorporate this protocol.

Policy 2.0: Smart Operators Increase Profit Without Rebuilding
|
|
Service providers need to look at how policy-based solutions in their networks can move beyond just dealing with pure cost control to revenue generation. Network-based policy solutions deployed to date have dealt with enabling basic service tiers and fair usage models in terms of QoS and monthly quotas. However they have largely been lacking in their ability to apply policy rules at a more granular service/application level or apply rich real-time context to the policy decisions being applied.

Mobile Video: Identifying Win-Win Pricing Plans
|
|
How valuable is video for mobile users? Would they be willing to pay more for video services that do not count against their data plan? If so, how much would they pay? Tekelec has conducted primary research that gauges user views regarding the relative value of mobile video as well as their reaction to various pricing models.

The Black Hole of 4G Indoor Wireless Coverage
|
|
Coverage gaps exist in metropolitan, suburban and urban communities in every wireless network. Research suggests that 20% of churn is caused by only 6% of the networks cell sites. Although coverage gaps can be isolated, they continue to exist despite technical measures, standard procedures, and other failed initiatives.

What Wireless Operators Need to Consider When Choosing a Location Solution
|
|
The mobile geo-location industry emerged in the United States (US) in the late 90’s, after the Federal Communications Commission (FCC) mandated that all emergency calls (E911) from mobile devices must be located by wireless operators/carriers with specific location accuracy and reliability requirements. A variety of low, medium and high accuracy performance location solutions emerged as a result of the mandate. This article provides an overview of the different types of commercial location solutions, and the corresponding applications they enable based on performance criteria.

It's a Small Cell World After All -- LTE Alone is Not Enough
|
|
With mobile broadband traffic rocketing upwards, global operators are realizing that LTE alone won't be enough. It's not a matter of innovation or effort; mobile networks in their current macrocellular form have simply approached the limits of physics. Capacity gains at this point can only be incremental and are a direct by-product of how much spectrum the operator has at their disposal.
