What is Seamless Mobility?





Transparent, easy, uninterrupted and ubiquitous
access to information, multimedia and
communincation when, where and how we want it.

What is Seamless Mobility?



A widespread vision of the fourth generation (4G)
or next generation networks (NGN) includes the
cooperative co
-
existence
of WLAN, GSM/CDMA,
GPRS and UMTS.


The Mobile Nodes (MN) are increasingly going to
be equipped with multiple network access cards
and users will be able to roam transparently over
heterogeneous networks in a seamless manner.






What is Seamless Mobility?


The three C’s


Connectivity


Intelligently manages how connections
are made based on device and access network
capabilities, availability and preferences of the
interacting parties of the session (presence information).


Continuity


Controls the movement of established
sessions across heterogeneous networks.


Content


Enables the ability to publish and/or consume
information from anywhere at anytime.

What is Seamless Mobility?


The Device Client Plane supports all devices supporting a common client to
manage applications.


The Access Plane encompasses both wired and wireless networks.


The Transport Plane interconnects all elements through IP transport for
transferring
signaling

and bearer traffic and also contains media
adaptation functionality through media gateways.


The Control Plane supports the session control functions to establish, maintain
and release session resources as well as managing
QoS
.


The Applications Execution Environment Plane supports user applications
(like Push
-
to
-
X), their enablers (like authentication and applications such as
presence) and interaction control that’s supported by the service capability
interaction manager (SCIM).


Why all the fuss about it?


The world as we know it, is changing. Our
generation is driven by the need for access to:

IP telephony (SIP), IMS


Form the core of any
seamless mobility system. The IMS framework may
be referred to as the heart of any next generation
network system.


Challenges


Standardizations, architecture design and access
network coverage.
