HSDPA is an evolution of 3G W-CDMA
Network efficiency:
• Increased total network throughput
(capacity) at reduced cost per bit
• Supports up to double the number of
packet data users (depending on actual
data throughput)
 Most cost-efficient solution to increase
bandwidth
Speed:

Increases downlink peak rate up to
14 Mbit/s

Downlink rates per subscriber will range
between 2 and 3 Mbit/s. (384Kbps uplink)

Reduced delay

1. IMS Introduction
What is the IMS?
The 3GPP IP Multimedia Subsystem (IMS):

is a Sub-domain in the 3GPP Mobile Core Network.

was designed by the 3rd Generation Partnership Project (3GPP) to deliver/support/control IP-based
multimedia communication services.

enables and supports the integration of Real-Time- and Non-Real-Time Services .

supports Person-to-Person and Person-to-Machine communications.

1. IMS Introduction
IMS History

Originally defined by 3GPP as part of standardization for UMTS. 3GPP is a collaboration
agreement established in ’98 amongst various standards bodies comprising of:
ATIS (Alliance for Telecommunications Industry Solutions)

ARIB (Association of Radio Industries and Businesses)

CCSA (China Communications Standards Association)

ETSI (European Telecommunications Standards Institute)

TTA (Telecommunications Technology Association)

TTC (Telecommunication Technology Committee)

Goal was to increase the functionality of packet-switched mobile networks by supporting
IP-based applications and services.

First appeared in Release 5 of 3GPP specs.

Release 6 introduces inter-working with WLAN

Release 7 adds support for fixed networks together with TISPAN

FMC is …
 An IP-based communication infrastructure for
delivering multimedia services
 A new industry application to enable
seamless mobility and roaming between
fixed and mobile networks
 A network-centric architecture that extends
control through the operator to the end-user
 Open, standards-based
 A common service framework independent of
access technology
 An architecture with interconnection to legacy
networks built-in
 Based on standards extensible to an
IMS architecture
 A vehicle to deliver common services
to fixed and mobile endpoints
 Expanding the users choice of service
access
IMS isn’t …
FMC isn’t …
 A service or application
 A Service or a Product
 A vertical service architecture
 Just seamless Handover
