And ....by end 2003 access will be :
EN/FAD 109 0015
• 1 B fixed IP nodes (ISP access etc)
• 1 B mobile nodes
• 1 B circuit switched and high bandwidth nodes
and combinations thereof for various convergence services
• plus x Million Bluetooth machine-machine communications
• plus x Million xDSL etc nodes with n>10 logical users per node
• plus x Billion Mobile Internet sessions calling on services
• plus many Million Internet hosts (2001: 120 M, IPv4 limit approx
200 M)
thus putting in focus the need to solve IP address crunch in
some regions of the world, and add new capabilities in this
connection

Basic technical IPv6 evolution (with mandated
interoperability with IPv4 services)
• 128 bit addresses in terminals for global reachability and
scalability
• Acceptance,user friendliness and support : IPv6 self
configuration nodesIPv6 self configuring nodes
• Simplified header for routing efficiency and performance
• Deeper hierarchy and policies for network architecture flexibility
• Security with mandatory seemless IPSEC support of all IPv6
devices
• Bandwidth and mobility : header compression , soft hand
over,and MobileIP for computing devices
• Interoperability fixed/mobile
• Enhanced multi-cast support with increased addresses and
efficient flow control
Ericsson CCND/TC+LME/DT L-F
Multiple levels of mobility in Mobile networks ,
and relation with IP protocols
• Access level
– classical cellular,and Mobile-IP
• Network level
– Soft handover,and Mobile-IP (selectively)
• Roaming level
- Handled in network
EN/FAD 109 0015
• Application level

KEY ISSUES TODAY AROUND the USE of
IPv6 In COMMERCIAL COMMUNICATIONS
NETWORKS
EN/FAD 109 0015
• Identifying incremental service revenue sources for
operators derived from using IPv6,sometimes
alongsid IPv4, and match them against costs
• Identifying new service revenue sources for operators
derived from using IPv6
• Migration plans for infrastructure and integration
services,including OSS and Network management
DECISION PROCESS MUST BE IN
ORDER ABOVE

IPv6 opens up for changes in Business models
favorable to operators and users
-
-
EN/FAD 109 0015
-
Business /traffic/infrastructure/service business models for
IPv6/IPv4 mobile traffic and services (Ericsson Hungary)
Business concepts and technical DNS solutions allowing for
efficient management by operators of IPv6 addresses in relation
to subscriber profiles
Billing solutions with bundled IP/ non-IP IPDR and CDR tracking
(Ericsson EHPT)
Collaborations with operators and new users
Ericsson CCND/TC+LME/DT L-F
USE In HIGH SPEED INTERNET ACCESS
SERVICES
EN/FAD 109 0015
• Technical dominant IPv6 features:
-increased IPv6 address space
-IPSECv6 with both data encryption and user
authentification
• Incremental revenue :
-price multiple addresses and flows managed at same
cost (e.g Japanese 180 Mbit/s ISP’s)
• New revenue :
-price enhanced security features
Ericsson CCND/TC+LME/DT L-F
USE in STORAGE AREA NETWORKING
EN/FAD 109 0015
• Technical dominant IPv6 features:
-IPv6 address hierarchy
• Incremental revenue :
-more reliable management of large data stores
• New revenue :
- content provisioning into 3G enabled mobile services
without NAT handling
Ericsson CCND/TC+LME/DT L-F
USE in ENTERPRISE VPN’s and ASP’s
EN/FAD 109 0015
•
Technical dominant IPv6 features:
-existence of IPv6 “flow label” field
-MobileIPv6 integration
-IPSECv6 integration
-IPv6 address space breaking 4096 VLAN address limitation
-combination with 802.1p/q/r/s QoS and extended addressing features
•
Incremental revenue :
-”transparent LAN” services with reduced configuration costs
-reduced need to map VLAN ID’s at network-to-network transition points
•
New revenue :
- enterprise specific tarifing characteristics encapsulated into “flow label” field
-services from supplying enterprises with AAA servers for their VPN’s
-premium service revenue from mobile workers which take their virtual office with them with full security
-M-Business services which can only be deployed with IPv6 features from risk points of view
-CRM and logistics services where case/object labels and tags are linked to IPv6 addresses in
applications
Ericsson CCND/TC+LME/DT L-F
USE in MOBILE TERMINALS and CONSUMER
DEVICES
EN/FAD 109 0015
• Technical dominant IPv6 features:
-Neighbor discovery
• Incremental revenue :
-reduced costs in customer support from much stronger autoconfiguration at installation time (compare e.g. WAP 1.0 terminal
configuration via SMS with Mobile Internet service configuration
with IPv6)
• New revenue :
-video streaming onto mobile terminals with flow control
-personalized services obtained by user profiles (on server or on host)
by XML tags in IPv6 packets

-business models around fee based support ,provisioning or billing
made by operators for content providers , using aggregation of
services

And some other initiatives at Ericsson where IP
is in focus ...
EN/FAD 109 0015
• Joint venture with Volvo on Internet car (already
demonstrated)
• IP in Bluetooth components and systems (Ericsson
Microelectronics, Ericsson Technology licensing
company for Bluetooth technology)
• IP in building management (JV with Skånska and
others)
• and more to come...

EVOLUTION
For mobile and convergence networks , no doubt about
:
EN/FAD 109 0015
-the need for v6
-v6 advantages
-v6/v4 coexistence and migration need
but :
-lack of importance in IETF and some regions of the world as
to a realistic migration driven by cost of ownership and
competitive advantages at service level
-the absolute need for quality implementations
-reduce fears as to migration , retraining , legacy , etc...
Ericsson CCND/TC+LME/DT L-F
IPv6, conclusion
• Technology maturing
• Inevitable in mobile networks, coexistence in others
• Good Business models with IPv6
