•AIPN IP core NW
supports the mobility
required by cellular
operators, e.g.,
seamless mobility

•NGN IP core NW may support
nomadic mobility for FMC.
•NGN IP core NW may also
provide seamless mobility for
real-time traffic with MSI.

Mobility management for AIPN can be
used for NGN mobility as well

Expectation for NETLMM Protocol
From 3GPP Work
 Future Network with Evolved UTRAN needs to transport
huge amount of packets efficiently
 Network will be IP based network (All IP core Network), to receive
the advanced features of the Internet technologies.
 All IP core network provides mobility with;




Seamlessness (high quality handover)
Support for heterogeneous wireless access technologies
Network Controlled
Efficient use of wireless resources
etc.
From NGN Work
 To realize FMC, the same level of requirements exists in
NGN as well
We expect NETLMM protocol to satisfy the needs of
ALL IP core Network and Next Generation Network
