Figure II.3 – PMIPv6 signalling flows for handover

Table II.3 lists the functions that must be supported by the MAG and the LMA, and matches these functions
to those defined in clause 6.4.

Table II.3 – Mapping of Proxy MIP network entities
with MMCF functions

Entity Functional description Function

Initiates location update signalling MLM-FE
MAG Indicates tunnel set-up HDC-FE
Provides a tunnel end point L3HEF
Binds the local mobility information MLM-FE
LMA Indicates tunnel set-up HDC-FE
Provides a tunnel end point L3HEF

II.1.4 Hierarchical MIP

Hierarchical MIP [b-IETF RFC 4140] identifies two network entities: the home agent (HA) and the mobility
anchor point (MAP).

Table II.4 – Mapping of hierarchical MIP network entities
with MMCF functions

Entity Functional description Function
Initiates location update signalling MLM-FE

MAP Indicates tunnel set-up HDC-FE
Provides a tunnel end point L3HEF
Binds the local mobility information MLM-FE
HA Indicates tunnel set-up HDC-FE
Provides a tunnel end point L3HEF
