3. Goal Target Future-proof MIH What?
protected from consequences in the future, esp. pertaining to a technology that protect it from early obsolescence
What?
Make MIH “able to work” with current and upcoming/future technology
Includes standards as well as any proprietary technology/technique
How?
Extensible MIH
Of or relating to a system that can be modified by changing or adding features.
Adding new capabilities to the MIH system would not mandate changes to existing Media-Specific requirements or Upper Layer entities

4. Extensible
To make MIH extensible by putting emphasis on the Discovery, Registration and Format of messages
Discovery
Extensible discovery system to allow MIHF/Upper Layer Entity to discover Services available
E.g. specific events, commands or information
Registration
Not only to allow MIHF/Upper Layer Entity to request for events, commands, information but also to allow, deny or control what is exchanged
Format of messages
Unified format to allow for extensibility (New events, commands or information elements)
E.g. TLV; Event, Command and Information Primitives
21-05-xxxx

5. Proposed Changes To replace: 6.1.5 Primitives for Link Layer Events
With:
6.1.5 Primitives for Events

6. Proposed Changes To insert: 6.2.2 Primitives for Commands
The generic model of Command Service primitives specifies the format of commands that are passed from the MIH Function to the link layer and also from the upper layer entity to the MIH Function. The Command primitive is defined as:
CommandXX. request (CommandSource, CommandInformationSet) where,
CommandSource: is used to identify the command source entity where the command originated;
CommandInformationSet: is an extensible parameter that may contain implementation specific information and may be different across different commands. CommandInformationSet completely describes the command that is issued.
Command primitives typically do receive a response defined as:
CommandXX. response (ResponseSource, CommandResultSet) where,
ResponseSource: is used to identify the source entity where the response originated;
CommandResultSet: is an extensible parameter that may contain the result of the request and may be different across different commands.

7. Proposed Changes To insert: 6.3.3 Primitives for Information
The generic model of Information Service primitives specifies the format of information requests that are passed from the MIH Function to the link layer and also from the upper layer entity to the MIH Function. The Information primitive is defined as:
InformationXX. request (RequestSource, InformationRequestSet) where,
RequestSource: is used to identify the source entity where the query originated;
InformationRequestSet: is an extensible parameter that may contain implementation specific information and may be different across different queries. InformationRequestSet completely describes the query that is issued.
Information primitives typically do receive a response defined as:
InformationXX. response (ResponseSource, InformationResultSet) where,
ResponseSource: is used to identify the source entity where the response originated;
InformationResultSet: is an extensible parameter that may contain the result of the request and may be different across different queries.

8. Proposed Changes To replace: 8.3 Description ...
[2] MIH remote registration: Remote MIHF in different entities can register with each other to receive Media Independent Handover Messages including remote MIES. No registration is required for command services.
With: …
[2] MIH remote registration: Remote MIHF in different entities can register with each other to receive Media Independent Handover Messages. The MIHF or an upper layer entity may choose to allow, deny or control the handling of messages from the MIES, MICS and MIIS, depending upon the information exchanged during the registration process.
