Internet-Draft Decision for Mip type February 2006
Abstract
Currently, this comes from the policy associated with that mobile.
But a MS maybe has the MIP capability.We need a flag to know if a
MS need Proxy MIP capability.This document explains how we can
define a flag in dhcp option to state that a MS wish or doesn't
wish to have the Proxy MIP capability.

Internet-Draft Decision for Mip type February 2006
1. Introduction
Currently in some standards development organizations(SDO) some
simple IP terminal need to be implemented the MIP cability. That is
finished by network without the MS's mobility support. That is named
as PMIP(proxy MIP). But if all of the simple IP terminal should be
provided with the PMIP by PMIP-enabled network? Or if MIP-enabled
terminal can also have the PMIP support by PMIP-enabled network?
These requirements are needed to be defined.
This document defines a flag in dhcp option to indicate if a MS wish
to have the Proxy MIP support.
1.1. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in BCP 14 RFC 2119
[STANDARDS].

2. Overview
Network decide a MS need the proxy MIP is triggered by
some entry network progress, such as PPP,DHCP,ND etc.
Currently, PPP has a option to indicate the mobile
capability of a MS(simple IP or mobile IP). But others
didn't have.If we think it right, we should do this.

3. Implementation
When a MS entry into network,it utilizes some protocols to acquire
initial network argument.Those protocols maybe PPP/DHCP/ND etc.
We can indicate the capability of the mobility preference of this MS.
Then network can decide if need to do the proxy MIP for this MS.
Currently, PPP has defined this option.
How about DHCP / ND and others? also need ,right?

4. A example :use DHCP protocol to inform the mip type of MS
In DHCP protocol, we definedd a new option to indicate that if a MS
need the proxy MIP capability.
This flag should be used in both of stateless DHCP protocol or
stateful DHCP protocol.
This flag should be used in both of DHCPv4 and DHCPv6 protocols.

5. Security Considerations
Secure guarante1 can utilize the detail protocol defination.

6. Conclusions
We need let MS has the ability to inform network about it's capability
in the selection of mobility mechnism.
