WiChorus Intelligent ASN Gateway

Users are demanding a rich and satisfying broadband experience from the wireless connectiv-

ity. Increasingly, users are looking for a similar media-rich broadband internet experience in

the wireless world as they have in the wired world. Service providers are eager to capture this

enormous opportunity, but need a cost-effective, scalable solution, as well as creative new

ways to monetize these services.

Combining the advances of OFDMA technology with the power of IP networking, mobile WiMAX

has emerged as an ideal architecture to provide these services. Mobile WiMAX offers greater

bandwidth than previous technologies, an open ecosystem that promises compelling eco-

nomics and a simplified, flatter architecture that reduces complexity and cost. It has been

designed for IP traffic from the beginning and has robust QoS support to handle real-time

multimedia traffic such as video, gaming, and streaming music.

In the era of rapidly-increasing bandwidth demand but flat

to decreasing ARPUs, service providers need smarter wire-

less networks to improve margins. These smarter networks

can offer service providers greater control of their network

to optimize operational costs and enable new revenue

streams.

WiChorus is a pioneer in developing carrier-grade,

Intelligent ASN Gateway solutions that address these

requirements. The WiChorus intelligent ASN Gateway sits

in the heart of the WiMAX network, with visibility across all

subscribers and packet flows. Based on the industry-lead-

ing SmartCoreTM platform, the WiChorus solution intelligently

aggregates high capacity base stations while ensuring line

rate QoS, accounting and security for millions of subscriber

service flows. Leveraging ASN Gateway’s strategic position

in the network, the WiChorus solution also provides back-

haul and spectral optimizations that maximize utilization

of valuable network assets. Service providers can leverage

the WiChorus intelligent ASN Gateway solution to capitalize

on service differentiation opportunities, effectively monitor

and control traffic in the network, manage subscriber con-

nections and reduce overall operating costs. Based on the

WiMAX Forum’s NWG standards, the WiChorus solution is

designed to work with any NWG-compliant base station,

enabling service providers to choose best of breed solu-

tions for each component of their network.

High Capacity and Scalability

The WiChorus Intelligent ASN Gateway is offered on the

full range of SmartCore platforms, ensuring exceptional

performance and scalability. Designed to accommodate

higher capacity OFDMA radio links the SmartCore platforms

deliver much greater performance than traditional 3G

oriented offerings, along with line-rate QoS classification,

policing and statistics. In addition to high data capacity,

the WiChorus Intelligent ASN Gateway supports millions

of dynamically created service flows, ensuring sufficient

capacity for the largest networks.

Content Management

User demand for ubiquitous broadband internet access

presents operators with practical challenges along with

potential new revenue opportunities. Peer-to-peer video

download applications, for example, can quickly consume

network resources and impact the performance of the over-

all network. Based on service providers defined policies,

WiChorus solutions can identify and throttle peer-to-peer

traffic, ensuring optimal performance of the network for all

subscribers.

With the ability to manage bandwidth at a granular level,

and a deep understanding of real-time content, WiChorus’

Intelligent ASN Gateway also enables service providers to

create unique and differentiated services. These capabili-

ties, such as location-based ad-insertion, can be used in

creative ways to monetize the Internet and to provide

alternative revenue sources to traditional subscriber fees.

Subscriber Management

The WiChorus Intelligent ASN Gateway has complete

visibility of subscribers within the network, and leverages

this information to help service providers offer intelligent

scalable solutions tailored to subscriber’s requirements.

The WiChorus solution provides support for address

assignment, authentication, QoS authorization, and service

flow creation. In addition, security policies can be admin-

istered at a very granular level. Leveraging the SmartCore

platform, the Intelligent ASN Gateway provides ample

system resources to manage a large number of subscribers

for either fixed or mobile deployments.

Enabling Intelligent Wireless Networks

Accounting and Billing

The WiChorus Intelligent ASN Gateway supports exten-

sive accounting and billing options for service providers,

enabling them to effectively capitalize on service differen-

tiation opportunities. The ability to capture statistics at a

very granular level coupled with the ability to dynamically

identify and trigger charging based on network content

enables unique solutions for monetizing the Internet.

WiChorus also supports standard techniques such as pre-

paid (online) and postpaid (offline), and volume and time-

based accounting for individual subscriber service flows.

Mobility

WiChorus is a pioneer in delivering advanced mobility

solutions for OFDMA-based WiMAX. The unique hardware

and software architecture of the SmartCore platform

supports bicasting/tricasting and make-before-break con-

nectivity to ensure seamless handovers for real-time IP

streams. The WiChorus Intelligent ASN Gateway supports

intra-ASN and inter-ASN mobility along with robust support

for Mobile IP ensuring subscriber stations can readily move

about the network for nomadic, portable or fully mobile

applications. The WiChorus solution also supports paging

and idle mode to help optimize power efficiency of sub-

scriber stations.

Network Optimization

With a global view of the network, the Wichorus ASN

Gateway offers service providers the ability to optimize

critical network resources and reduce overall operating

expenses. Backhaul capacity can be strained with the

migration to higher capacity WiMAX base stations. By

shaping and policing traffic destined for base stations,

the WiChorus ASN Gateway solution improves backhaul

efficiency. Header compression and suppression

techniques further optimize traffic in the access network.

Robust QoS

Anticipating the desire for a variety of media-rich applica-

tions and services, WiChorus designed the SmartCore fam-

ily with extensive QoS and packet processing capabilities

to identify and manage traffic on a per subscriber, per flow

and per application basis . The WiChorus solution supports

creation, deletion and modification of services flows in

accordance with the WiMAX Forum’s standard QoS profiles.

Furthermore, the WiChorus intelligent ASN Gateway

provides shaping and policing of these flows to deliver

a consistent end-to-end experience for subscribers. The

WiChorus ASN Gateway solution also maps these service

flows to IP Differentiated Services (DiffServ) framework

for transport across IP networks. In addition to providing

per subscriber/per flow traffic management, the WiChorus

intelligent ASN Gateway can dynamically apply QoS based

on content, such as application type, for maximum

flexibility in defining services.
