The ability to use voice, mobile apps, SMS, email, websites, chat, video, and social media through a single device is forcing operators to rethink their mobile strategies in the form of offload. With the increased data usage, operator networks become increasingly congested. As such, a smart and dynamic connected interaction is necessary to allow better traffic management with particular capabilities of the device with which it is characterized.
In this paper, we will examine how dynamic data offloading with 3GPP based Access Network Discovery Selection Function (ANDSF) plays its role in the implementation of selective offloading. ANDSF as specified in 3GPP standards describes how the inter-system mobility between 3GPP systems and non-3GPP systems (WLAN, WiMAX, CDMA) policies and priorities can control the conditions for which a device connects to which wireless network. As mobility is becoming a mainstream for customer engagement, operators must ensure contextual continuity is preserved through an integrated approach.
Mobile networks are now dominated by data. If we rewind back to a decade ago, smartphones and application stores were unheard of. Twitter and Facebook were not in existence and YouTube wasn’t as popular. Culturally, consumers are valuing the need to be socially connected in the present day Internet.
The traditional cellular network cannot cope with the increase in data and signaling traffic that is generated and thus is driving carriers in the direction of offload. The Phase 1 approach was centered on immediately relieving congestion on the network by encouraging offload to any available Wi-Fi hotspot. In this second part of the five part offload series, we draw attention to Direct Internet Offload. The concept of Direct Internet Offload is nothing new, but has taken a slight shift considering Wi-Fi’s popularity. And the flexibility to integrate them into mainstream network design offers transformative opportunities for carriers without losing sight of the commitment to make the user experience secure and controlled.
Managing Data Offloading Securely Over WLan Access Networks With I-WLanGreen Packet
Cellular operators are increasingly shifting their focus for alternative wireless access methods to manage data offload. Legacy cellular networks were designed for low bandwidth consumption and insufficient to cope with the growth of data requirements today. Although operators continuously upgrade their networks with greater capacity and advanced technologies, heavy investments for cell build is not an economical approach in the longer term.
The availability of Wi-Fi hotspots are highly accessible and appropriate for data offloading. Taking advantage of the unlicensed spectrum and better bandwidth utilization, data offloading can be achieved with lower cost per bit. In this paper, we present I-WLAN to effectively manage data offloading securely between 3GPP and non-3GPP networks. We will also be exploring the different network use scenarios of I-WLAN in enabling simple unified EAP authentication and subscriber policies.

Dynamic Data Offloading : Connect Intelligently With ANDSFGreen Packet
The arrival of varied smartphones and devices has inevitably encouraged greater data consumption.
Users are now more sophisticated and demand nothing less than best network performance. Smartphone generally accounts for higher ARPU and represents potential new revenue streams for enabling quad play services. Operators are aggressively addressing these challenges and improving the quality of their solution to retain existing customers and offering better service experience to build loyalty.
WiFi adoption as data offloading is gaining momentum as it improves user experience while lowering the cost of service providers. Correctly implemented, it can ease up to 20% of traffic with substantial impact of freeing up the spectrum and load balancing. Offloading data to WiFi hotspots is economically attractive, because many carriers already operate a substantial number of hotspots.
In this paper, we will examine how dynamic data offloading can be further optimized with 3GPP based Access Network Discovery Selection Function (ANDSF). ANDSF describes how the inter-system mobility between 3GPP systems and non-3GPP systems (ie: WLAN, WiMAX, CDMA) policies and priorities can control the conditions for which a device (UE) connects to which wireless network.
This is the paper that started it all. An early thought piece discussing the widening profitability gap for mobile network operators and positing a disruptive architectural response. Originally branded "Adaptive Backhaul", the concept already had most of the ingredients now found in the Mobile Edge Cloud: content caching, application hosting and acceleration deeply distributed in the radio access network. These ideas have been developed by innovative startups such as Saguna Networks and have formed the basis of important new offerings from Tier 1 network equipment vendors, such as NSN's Liquid Applications.

This paper focuses on the portable Pocket Modem, a device that leverages on the synergy offered by WiMAX and WiFi. It examines how this synergy benefits users and provides a better connectivity experience.
Drive Mobile WiMAX Adoption With Versatile ModemsGreen Packet
Mobile WiMAX has tremendous potential with its advantage of mobility and high bandwidth support. In reality today, approximately 65% of subscribers worldwide use WiMAX for fixed purposes which undermine WiMAX’s mobile promise.
How can WiMAX Operators play their part in driving the adoption of Mobile WiMAX in their countries? The answer lies in having versatile modems that provide excellent performance indoors and outdoors to answer the call of mobility.
This paper defines versatile modems from a technical and user perspective and explains how this type of modem can promote the take up of Mobile WiMAX.
Positioning WiMAX As The Personal Broadband TechnologyGreen Packet
More and more users want a broadband connection that is exclusive, follows them around and is available 24/7. Welcome to the concept of personal broadband. To realize this concept the chosen broadband network has to be able to deliver users’ expectations. Meanwhile, appropriate user devices must be employed. This paper presents WiMAX as the best technology to fulfill personal broadband and imparts what users expect from their personal broadband device.
Hostless : Simple Connectivity For WiMax DevicesGreen Packet
4G wireless nomadic devices in the form of USB dongles and Pocket modems are fast becoming the preferred devices for wireless broadband access amongst 4G operators. Due to benefits of lower cost and smaller form factor, 4G wireless nomadic devices now account for 39%* of total WiMAX devices shipped in 2010, and this tendency is set to continuously increase in the coming years as 4G becomes pervasive.
Greenpacket 4G nomadic devices now provides an option to allow the use of generic Virtual Ethernet link protocol (USB CDC or RNDIS) to connect with these external host controllers running on any operating systems as an alternative to the traditional CU approach. We call this feature “Hostless” connectivity. Very similar to how an end-user would connect a USB memory stick, this new Hostless feature can be visualized as a generic version of a CU, borrowing the native USB Ethernet driver and management features from the host operating system.
This paper explains the implementation scenarios of both the CU approach and Hostless approach to match specific needs. We will then dive in detail to understand the concept background of Hostless by looking at the system architecture and describing the step-by-step of how Hostless works within the host terminal from an end user perspective.
Help Desk 2.0 : How You Can Empower A Paradigm Shift In Customer CareGreen Packet
Worldwide, across industries, customer care is one of the top concerns. In the telecoms sector, next to network quality, customer service is rapidly becoming a key success factor to ensure best-in-class service. In spite of its importance, operators continue to care for their customers through legacy CRM systems, which are inadequate in meeting the demands of today’s customers.
Operators need a paradigm shift in their style of customer care to protect the interest of both subscribers and the operator themselves.
This paper (part 1 of a 3-paper series) introduces Help Desk 2.0, the next generation help desk system that revolutionizes current practices through automated and proactive customer care mechanisms to ensure service excellence, enhanced top line and sustained bottom line. In the upcoming paper, we will focus on the business advantage of employing Help Desk 2.0 focusing on cost control, revenue enhancement and retention. This will be followed by a technical interworking paper, centered on how to implement Help Desk 2.0.
Self Service Customer Care For Next Generation NetworksGreen Packet
Smartphone devices have dramatically changed the way consumers consume data. The need to be connected anywhere and anytime is driving service providers to put focus into customer experience to grow customers, build loyalty and drive profits through new services. As a result, the expectations of service experience from the end-user are heightened and cannot be underestimated.
Service providers are under pressure to deliver customer experience that separates them from the competition, while at the same time trying to delicately balance their revenues and managing costs for near term gain and longer term success. In this paper, we outline the scale of issues faced in mobile device and service care that impacts both service providers and end-users beyond connectivity. With a broad range of services and wide variety of applications, the smartphone requires more complexity to handle a multitude of firmware and software configurations which legacy CRM systems are inadequate to deal with today’s customers.
Remote device support and service care is a key component to tackle the demands of escalating costs in customer care. Service providers are seeking integration onto backend systems without incurring heavy infrastructure changes and ensure the best fit into the existing operations through automated and proactive customer care mechanisms to ensure service excellence and thus prevent service quality degradation.
Mobility Management For Next Generation NetworksGreen Packet
Increasingly, operators worldwide will be faced with a similar challenge of managing data congestion over multiple access networks. With networks evolving into LTE, operators would need to carefully assess the technology fit into integrating complementary nature of multiple access networks into an all-IP flat architecture. An all IP flat architecture helps to tie heterogeneous access networks that devices can attach to access end-user services. Communication devices today are able to connect with more than one type of wireless technologies to the “web of things”. An end-user will connect to a Wi-Fi hotspot, if within range. When moving away from range, the communication link is handover to for example, UMTS. The motivation of inter-working lies in marrying the diverse strengths of each communication technology. High-bandwidth data communication inherent in WLAN lacks mobility. Conversely, cellular technologies such as UMTS succeed in highly mobile environments, but limited in bandwidth. Although cellular networks are evolving from today’s 3G to LTE that brings promise of capacity leaps (by nearly 4 times), the overall data growth projection will outpace LTE deployments and fill up very quickly.
The immediate need to curtail congested network and effectively manage mobility is imminent to accommodate the data traffic on their networks. The impact of inter-mobility between inter access technology together with various types of mobility support including 3GPP legacy network and non 3GPP is necessary to provide a target low-latency, higher data-rate, all-IP core network capable of supporting real-time packet services. Some of the available IP mobility protocols lack sufficient control to the network to optimize the handover process and do not handle well with slow connection setups of some wireless technologies. This paper highlights the potential approaches of bringing together mobility technologies that are available and how these approaches contribute to resolve operator concerns in deployment of services and combating congestion, access technology integration and evolution to LTE from legacy 3GPP networks.

Abstract
Smart devices (smartphones and tablets) have simplified consumer access
to services across multiple channels. The ability to use voice, mobile apps,
SMS, email, websites, chat, video, and social media through a single device
is forcing operators to rethink their mobile strategies in the form of offload.
As a result of increased data usage, operator networks become
increasingly congested. As such, a smart and dynamic connected
interaction is necessary to allow better traffic management with particular
capabilities of the device with which it is characterized.
In this paper, we will examine how dynamic data offloading with 3GPP
based Access Network Discovery Selection Function (ANDSF) plays its role
in the implementation of selective offloading. ANDSF as specified in 3GPP
standards describes how the inter-system mobility between 3GPP systems
and non-3GPP systems (WLAN, WiMAX, CDMA) policies and priorities can
control the conditions for which a device connects to which wireless
network. As mobility is becoming a mainstream for customer engagement,
operators must ensure contextual continuity is preserved through an
integrated approach.
This can be achieved with a client-based implementation as described
with reference to applying real-time connection state and policy control.
Policy enforcement and policy management is mapped more accurately
with an overall knowledge of the network at any given point of time.
By intelligently managing the distribution of network load, congestion can
be strategically minimized.

4. APPLICATION NOTE Overview - 01
Overview
Recent market research resonate the general consensus that Wi-Fi
offload is finding a strong foothold in networks. This exponential growth of
data traffic is forcing operators to evaluate mid to long term migration
strategies to LTE while in need for short term strategies to relieve their
congested macro cellular networks.
Based on analyst studies from Comscore and Heavy Reading, a lot of
data traffic is already being offloaded to private and public Wi-Fi networks
in homes, at work and public places. The estimates show 20% to 80% of
smartphone data traffic is traversing these private and public Wi-Fi
networks. Meanwhile, network equipment vendors are also racing to
develop carrier-grade Wi-Fi infrastructure solutions as part of their
solution spread. Similarly operators are experimenting how to fully
integrate Wi-Fi capabilities into their networks to offload data traffic from
their primary 3G network. Although still lacking understanding and
analysis of determining where, when and if using Wi-Fi offload actually
helps the operator’s business case, operators are more willing to
experiment than risk further deterioration of their networks.
Consumer behaviors are changing with the use of multiple devices across
work, businesses and leisure with demands of consistent quality
experience. Also using multiple applications on each device is common –
a situation where operators no longer control applications. These
applications and their operating systems are placing an extraordinary
amount of signaling on the network, resulting in unpredictability. By
dynamically adding network capacity where and when it is needed
through an incremental, selective and cost-effective upgrade,
policy-based Wi-Fi offload can help address the growing demand for
data. The motivation of selective offload is aimed towards achieving
greater user experience after offload.
5. APPLICATION NOTE Mission Critical Experience Counts - 02
Mission Critical
Experience Counts
Mobile users have long embraced traditional messaging services but it is not
enough today for operators to continue on that business model. Today’s
converging communication environment offers a wide range of alternatives.
Strikingly, subscriber loyalty is shifting from the mobile network operator to the
device itself and the capabilities it offers (e.g. HD video, in-built camera,
face-time). Price-sensitive customers particularly find over-the-top (OTT) services
like Skype, WhatsApp and Viber appealing, which offer enhanced features that
SMS and MMS-based service lack. The propensity of OTT displacing traditional
SMS, MMS and voice-based service revenue is real. Subscribers simply no
longer differentiate the various media platforms as separate services, but as a set
of integrated communication features as necessary.
Recent research indicates that OTT services are impacting operators’
bottom lines significantly. Of which, 3rd party messaging services cost
operators over $8billion in SMS revenues in 2010 and nearly $14billion in
2011, according to technology analyst Ovum. To add on the list of operator
troubles, these OTT applications for most parts are not optimized and can
cause considerable drain on network resources. The constant signaling to
the mobile network generates unnecessary signaling traffic and ultimately
cause congestion and slow down speeds. In some cases, it may cause
network outage and eventually degrading the user experience. Operators
need to find ways to reclaim the control of their networks and pro-actively
manage bandwidth management from a multi-dimensional approach. One
such method is through the policy management systems and consideration
of a converged 3G-Wi-Fi environment. Making Wi-Fi as secure and easy to
use as cellular is the way forward for the future of hotspots.

Taking Charge,
the Power of Enriched Experiences
The advent of ubiquitous connectivity and the advancement of content
driven experience into smartphones, tablets and living rooms have raised
the bar on consumer expectations. Coupled with that, mobility puts a
different set of challenging requirements on the back end and core
networks. Today users expect personalized service from their service
providers; they expect their network to be smart enough to recognize the
type of device and the access medium on which they are consuming
content and offer the same personalized service and quality assurances
regardless. According to Cisco's VNI (Visual Networking Index) report, there
will be an estimated of 2 billion M2M connections in 2015. Of which, many
of these new applications are enabled by mobility.
These predictions provide an insight to potentially influence how operators
can map out their networks to match new generation network needs. The
near-term strategy is to avoid becoming dumb pipes and fight against
revenue leakage by focusing on the user experience. From a longer term
outlook, it is vital for operators to monetize additional cellular usage by
investing in and enhance the capabilities of existing mobile networks
alongside carrier-grade Wi-Fi deployments, to identify and prioritize
applications that are reliant on the inherent benefits of cellular networks and
Wi-Fi. Most importantly operators must exploit inventively the pricing
strategies that allow operators to realign the price of access with the
perceived value by the vast majority of customers that will have a profound
impact on the mobile network.

Moderation of Services
Advances in network technologies had brought some relief, but only
address partly the issue of congestion. Therefore, more needs to be done
in order to holistically tackle the issue. By combining device-based solution
with network-based solution, Greenpacket provides a relatively
straightforward resolution. The series of Intouch Mobile Data Offload
solution is designed to give operators the flexibility to enhance scalability,
increase implementation speed, and improve data offload measures
through a phased approach. The ANDSF enabled Dynamic Data Offload
client works by retaining to a certain extent the level of visibility on the user
policy as opposed to blindly offloading the subscriber onto Wi-Fi networks.
Growth in data volumes if not properly managed can cause disruption.
By allowing moderation of service access on specified time, location and
network conditions, it can significantly help monitor network resources so
that it does not suffer unnecessary overload. Case in example, periodic
traffic surge is noticeable during peak hours. Instead of adding costly new
cell sites as one of the measures, operators can take advantage of
dynamic data offload early to detect congestion and shift traffic to
alternative Wi-Fi networks wherever available by enforcing operator policy
for preferred network access.
The motivation for implementing ANDSF is largely driven by the need for
better bandwidth utilization and ultimately better moderation of service.
Control and optimization for mission critical applications like VoIP, P2P
streaming and video streaming is necessary to ensure good user
experience. Operator-controlled and service-aware selection of the type of
wireless networks can bring benefits to the operator looking to offload
using Wi-Fi. The ability to retain visibility of which IP traffic remains on Wi-Fi
(e.g. best effort Internet traffic like email, web browsing, which are
non-revenue generating) and which IP traffic is maintained on the 3G link
(e.g. VoIP that is quality sensitive). This may contribute to better
understanding of the traffic models relevant to minimizing congestion.
Also, to better integrate the common provisioning of service, billing and
roaming to be much easier between the carrier network and Wi-Fi.

Injecting Meaning to Ubiquity
Pervasive connectivity and ubiquitous coverage are two very important
elements for delivering seamless experience. The seamless experience can
only be meaningful, with greater appreciation of the interpretation of
network and device level state information.
Today’s networks comprise of multi radio scenarios, likely a mix of WLAN
and 3GPP based networks. These access networks are not “aware” of
each other. Although smart devices today are more advanced than before,
it still lacks the intelligence to control the access network of the device (UE)
state in the other access network. Given that WLAN is not a “controlled”
access network and works in unlicensed spectrum, the only network
condition of radio quality and the performance through that WLAN is made
available only to the device (UE). Hence, the device (UE) is in a better
position to decide the connectivity options. Most often, the network
selection is governed by a default connection manager in the device (UE)
that is limited in many ways.

Offload client has enough intelligence to enforce operator policy in real-time
by selectively triggering the connection of device (UE) to a given threshold
or the preferred available access network types based on inter-system
mobility policies. The network load can be balanced or spread out to the
availability of network radio resource at the point where congestion is likely
to occur without compromising the user experience in the process.
The single-client software works to converge multiple network access and
executes data offloading transparently. Incorporating customizable features
and capabilities, the Dynamic Data Offload client can intelligently detect the
availability of access networks based on signal strength and user policies
allowed for accessing certain data services on a cellular network (such as
3G) and if there are less congested alternative networks (such as Wi-Fi,
WiMAX, EVDO) available in the same vicinity. Operators can also opt to
customize these policies based on application aware policy, device policy,
subscriber policy and time-based policy to trigger data offload. By
switching the user from 3G to Wi-Fi without interruption to connectivity,
it ensures a seamless user experience.

policy management and control component1 (e.g. PCRF server). Instead of
relying heavily on the network policies enforced at the core network
(back end), actual decision making process can be selectively made
real-time as a result of direct relation to the user activity at the device (UE).
As a result of the in-built intelligence, the client can determine the best
available networks for data offload within the pre-loaded local policy in the
absence of network policy. The added advantage of the make before break
in accordance to Mobile IP specification further enhances the seamless
connection experience, without requiring a switch of different connection
profiles. The added intelligence of ANDSF brings benefit to the negotiation
of connection state by various operator policies supported as:
• Location-Aware Policy – cell ID or associated SSID is checked against
the policy database for specific locations that are preferred/relevant
• Access Network Discovery Policy – list of available access networks
(RAT type) that are available within the vicinity and facilitation of
prioritized access network selection for network handover
• Time-based Policy – configuration of policy validity “time to live”
interval to current location and profile
• Subscriber-based Policy – dynamic allocation of subscriber package
and profile

during peak congestion periods, specific times of day, application-specific
services or combination of them, operators can have the flexibility of
ensuring good QoS at times of high capacity demand. The Intouch Mobile
Data Offload portfolio can also be extended to include an analytics driven
ability to differentiate other solution in the market, whereby QoS is highly
desirable and work in tandem with PCRF.
The client will check the existing policy. If the policy is alive, it applies the
current policy. Otherwise, the client will request for a new policy. Similarly,
the business rule engine in the PCRF pushes dynamic and subscriber
specific policy decisions by checking the subscriber specific data (e.g.
subscriber package, access entitlement/restriction) accordingly. Based on
this information, PCRF dynamically modifies the connection policy rule
depending on the type of policy control required, acting as a policy
management point. The policy decisions are delimited by validity of the
location, time of day and discovery information. The client learns of
subscriber state and network state parameters over time to detect the
corresponding bearer (Wi-Fi, 3G, WiMAX) to the suitability of context
(service type, device type). These parameters ensure that the operator
retains visibility of which IP traffic are critical and retained on the 3G or
Wi-Fi connection.

Conclusion
Mobile traffic demands will likely exceed network capacities in the short to
medium term, despite planned LTE deployments. The enabling of rich
communications is by far the greatest influence Wi-Fi have had on the user
experience. Despite Wi-Fi offload featuring significantly on the operator’s
agenda, other aspects that Wi-Fi play out in the cellular network is far and
wide in between. Operators should not underestimate client device behavior,
as it brings a range of use cases, imminent in today’s diverse networks and
avoid falling into the trap of building networks in silo – they must instead use
methodologies that exhibit true performance and measure user experience
through connectivity, mobility and inter-operability.
Dynamic data offloading is necessary to minimize congestion. The earlier a
congestion trigger is controlled and managed, the earlier the operator can
continue to improve the distribution of network resources from the
perspective of spectrum planning. Since networks do not behave identically
nor follow the same traffic model, data offloading exercise can facilitate
balancing the load whenever congestion occurs. Policy enforcement and
policy management is mapped more accurately with an overall knowledge of
the network at any given point of time, rather than a silo representation at the
aggregation point at the backend. More and more operators are embracing
data offloading as means to satisfy the bandwidth requirements. With
dynamic data offloading methodology, the operators can maximize the
network’s core assets while holding off CAPEX intensive investment either
for 3G or LTE. Through the extension of dynamic policy controls that is
integrated, operators can truly benefit from alleviating mobile data burden it
places on the mobile network.
