New HSGW Features
This section identifies new HSGW features available in release 15.0.
HSGW PMIPv6 Heartbeat
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.

Access Gateway (MAG) and the Local Mobility Anchor (LMA) set up tunnels dynamically to manage mobility for a
mobile node.
Path management mechanism through Heartbeat messages between the MAG and LMA is important to know the
reachability of the peers, to detect failures, quickly inform peers in the event of a recovery from node failures, and allow
a peer to take appropriate action.

a peer to take appropriate action.
Per RFC 5847, PMIP heartbeats from the HSGW to the P-GW are now supported. CLI has been added to configure the
heartbeat variables. Show commands have also been modified to display the heartbeat configuration and the statistics
heartbeat variables. Show commands have also been modified to display the heartbeat configuration and the statistics
HSGW to Send Destination P-GW in New AVP
The Diameter attribute “Destination-PGW” is supported.
Important:
Note that not all attributes listed here are supported in all dictionaries. For information on attributes
supported in a custom dictionary, contact your Cisco account representative. For information on attributes supported in
standard dictionaries, refer to the Diameter Attribute Quick Reference appendix in the AAA and GTPP Interface
Administration and Reference.

Option to Send BSID in PBU Refresh from HSGW
When HSGW extends the registration lifetime, the PBU (Proxy Binding Update) it sends must include the BSID (Base
Station Identification). The BSID must be the last seen BSID from the RNC. The PBU sent during de-registration must
also include BSID.

also include BSID.
A new CLI has been added for mag-service to enable the user to pick and choose which PBU packets will have the
BSID information and which ones will not. By default, the existing behavior of sending BSID in initialization PBU and
update PBU packets will remain unchanged.

In addition, a new trigger has been added to update the BSID change information in the MAG driver for local base
station migrations. For this trigger, no update PBU packet will be sent to P-GW.
