Vertical Telecom Network Infrastructure
For relatively small #s of apps, vertical approach is simpler, cheaper and faster
For larger #s of more complex apps, non-optimal duplication, costly, slower
No separation of the application layers vs. network/access layers
Reduced interoperability at the application and network layers due to service specific
network gateways and elements
Higher operational costs to maintain service-specific vertical silos
Higher development costs to extend existing services, as well as launch new ones

“We’re borrowing from the software
development model … ideas like objects and
reusable components. To accelerate service
introduction, we want to let people pick and
mix components to build their own services.”
Daryl Dunbar, BT’s director of 21st Century
Network (21CN) design and development.

IMS Features Overview
IMS architecture consists of 3 key
“layers”:
Application Server layer
(applications)
Session Control layer (SIP network)
Media layer (PSTN/circuit switched)
Based on Internet industry
standards, not Telco standards
Built-in secure identity and privacy
management
Device and access-agnostic
Context-aware services e.g.
Presence
Auto-roaming of services
Flexible charging models
Negotiate Quality of Service
(QoS)
Fixed/Mobile convergence (FMC)

IMS Component Architecture
A/S = Application Server
IMS service logic
SIP interface into IMS core network
3 types: SIP, Parlay, CAMEL
IM SSF = IP Multimedia Service
Switching Function
2G wireless application platform
CAMEL Service Environment
CSCF = Call/Session Control Function
SIP proxy servers
Session control & signalling
3 types: Serving, Interrogating, Proxy
HSS = Home Subscriber Server
Subscriber database
Maintains home subscriber profile
MRF = Media Resource Function
Signalling plane – Media Resource
Function Controller (MFRC)
Media plane – Media Resource Function

Charging in IMS
Online Charging
Based on charging event creation
Immediate Event Charging (IEC) (type EVENT_RECORD)
Event Charging with Unit Reservation (ECUR) (type
START/INTERIM/STOP_RECORD)
ECF (Event Charging Function) uses charging event to support OCS
Unit determination and rating
Centralized on the ECF
Decentralized on the AS/MFRC
Offline Charging
Based on CDRs collection
IMS network elements report accounting information to the CCF using the rf
Interface
