DHCP Options for 3GPP Service
draft-liu-dhc-3gpp-option-03.txt
Abstract
This document defines a new option that can be used by DHCP clients
in their signaling sent to DHCP servers, when those clients need to
associate a request for an IP address or IPv6 prefix with a given
3GPP packet service.It is intended for scenarios of interworking
between a non-3GPP access and a 3GPP network.

and deliver configuration parameters to dynamically configured hosts.
The changes to [RFC2131][RFC3315] defined in this document defines
the use of 3GPP specific option transferred to DHCP server by DHCP
