Proxy Mobile IPv6 (PMIPv6) is a
network-based mobility management protocol to provide mobility without
requiring the participation of the mobile node in any PMIPv6 mobility-related
signaling. The core functional entities, Mobile Access Gateway (MAG), and the
Local Mobility Anchor (LMA), set up tunnels dynamically to manage mobility for
a mobile node.
In an earlier release, support was added for the standardized PMIPv6
protocol between the NEMO and an SAEGW running on the ASR 5500. This support
included processing of IPv4 prefixes at NEMO-LMA with IPv4 transport. With this
release, the support is extended, including Session Recovery and ICSR support,
for the following functionalities:
Processing (add/modify/delete) of IPv6 and IPv4v6 prefixes at
NEMO-LMA with IPv4 transport.
Processing (add/modify/delete) of IPv4, IPv6, and IPv4v6 prefixes
at NEMO-LMA with IPv6 transport.
Generation of UDR for base call containing NEMO IPv4, IPv6, or
both IPv4 and IPv6 prefixes information for NEMO IPv4 transport only.
Heart beat support for NEMO-LMA with IPv6 transport.
UDR with NEMO prefixes information is generated for the base call in
the following cases for NEMO IPv4 transport:
During initial NEMO call registration where UDR contains all the
NEMO prefixes (IPv4, IPv6, or both IPv4 and IPv6), and number of prefixes.
During renew/update of NEMO prefixes where UDR contains only the
new NEMO prefixes (IPv4, IPv6, or both IPv4 and IPv6 present in renew request),
and number of prefixes.
During call cleanup:
If base call is cleared ahead of NEMO call, UDR with existing
nemo prefixes is generated.
If NEMO call is cleared ahead of base call, UDR without
prefixes is generated (as NEMO information is already deleted).
