Wireless Evolution to 3G
Wireless cell phone use has been one of the big Telecom success stories in last 20 years
GSM and CDMA digital wireless introduced in 90’s and still in use today (2G)
Move to wireless data applications (2.5 G / GPRS/ EVDO) in last few years
Promise of 3G (Third Generation Wireless) is to offer bigger pipes, much greater flexibility and preserve/extend mobilility

Impact of IP
First round of 3G based on circuit switched networks
In parallel, big move to Voice over IP in landline networks
Wireless community also wants to move to IP, but needs to upgrade infrastructure
Move to IP and desire to support new, richer multimedia applications were new drivers
Result: New IP-based infrastructure needed for 3G networks

Introducing IMS
Wireless industry sought to solve these issues and move to IP-based services– Resulting architecture is called IP Multimedia
Subsystem or IMS– Devised by the Third Generation Partnership
Project (3GPP)– Also endorsed by the CDMA based 3GPP2– IMS began in the wireless community, but is now
being accepted by a variety of carriers and industry organizations
– Now envisioned for use on many different types of networks, including WiFi and landline

IMS and Application Developers
IMS is the new wireless service architecture– Over time, it will fully replace existing 2G service
approaches
Well suited for applications which use multimedia and communications
Application developers can focus on the application or service– IMS provides the infrastructure with tools like the
MRF for rich media and Diameter for accounting

Building Blocks for 3G - IMS
IMS provides separates applications from underlying infrastructure
Promotes scalability and ability to re-use common components to support multiple applcations
An example is the MRF or Media Resource Function of IMS– MRF handles media handling, including Voice
Play/Record, Video Play/Record, Tone Detect – Collect, …

Building the Network – MRF Example
Many of the 3G – IMS components can be built using standard off-the-shelf servers
For example: – MRF can be built using PC server based CPUs– Movement toward MRF as Software that can run
on various hardware platforms Examples of MRF Topology Choices
– ATCA / uTCA Chassis with CPU blade– Blade Server – 1U / 2U appliance– Stratus Fault Tolerant Server
