Introduction(1/2)


Mobility support for Internet access has
evolved and client may required VoIP
services with mobile device.
The most concern is the disruption time
to process the handoff of an VoIP
session.
Introduction(2/2)



We can use the off-the-shelf technology
in network layer with mobile ip.
Or we can add some new approaches in
SIP or H.323 in application layer.
The main goal is to compare these
solutions and find which one is the
simplest or the best.
Approaches(1/3)


Mobility can be realized in the network
layer by using mobile IP.
Draft for seamless handoff has been
proposed such as fast handoff.
Approaches(2/3)



Mobility can also be realized in the
application layer by using SIP.
MN can informs the CN via a SIP ReINVITE message with any address
change.
Shadow registration[1] can improve the
performance during handoff.
Approaches(3/3)


We can also use H.323 to achieve
mobility in application layer.
MVOIP[4] can improve the performance
during handoff.
