3.1 Definitions

For the purposes of the present document, the terms and definitions given in TR 21.905 [1] and the following apply.

The following terms used in this Technical Specification are defined in RFC 6275 [14]: Home Address, Care-of Address, binding cache, binding cache entry.

The following terms used in this Technical Specification are defined in TS 23.402 [3]: Home network prefix.

Home Agent: The Home Agent functionality consists in the DSMIPv6 anchor point functionality described in RFC 5555 [2] and in RFC 4877 [6] and the extensions defined in RFC 5648 [7] and RFC 6089 [8]. As per TS 23.402 [3], the HA functionality is located in the PDN Gateway. As per TS 23.327 [4] the HA functionality can be either a standalone entity or co-located with the GGSN or with the PDG.

Local Operating Environment Information: This is a set of implementation specific parameters which describe the local environment in which the UE is operating.

routing address: A routable IP address. In DSMIPv6 this is either the CoA (visited link case) or the HoA (in home link case).

routing filter: A set of packet flow IP header parameter values/ranges used to identify one or more IP flows for routing purposes.

routing rule: The association of a routing filter with a routing address.
