3. Advantage
Previous MIH group manipulate commands indicate new group members by complete subtree.
We can reduce their data size by using two type of indication methods.
Indicate group members by complete subtree. (The current command)
Indicate non-group members by complete subtree.
MuGM

4. Flow Diagram: Generate Complete Subtree
Input : Group Management Tree,
MIHF IDs of the group members
We will present examples of the condition by below slide.
MIHF IDs satisfy a condition?
Yes
Generate Complete subtree of the complement set of the MIHF IDs
Generate Complete subtree of the MIHF IDs
Set Complement = 0
Set Complement = 1
Output: Complement, CompleteSubtree fragments, SubgroupRange
MuGM

5. Flow Diagram: Process Complete Subtree TLV
Input : Group Management Tree, Leaf ID,
Complement, CompleteSubtree
Complement = 0
Yes
Is Leaf ID covered by Complete subtree?
Is Leaf ID covered by Complete subtree?
Yes
Yes
Go to Step [join] or [stay]
Go to Step [Leave]
MuGM

6. Examples of the condition
Result of comparing data sizes of two complete subtrees
CompleteSubtree of group member
CompleteSubtree of non-group member
Choose smaller one.
The number of new group member
The number of all members managed by the group management tree
The number of new group members < 2

7. Change requests
Define a data type of Complement in Table F.24 and Type Values for TLV encoding in Table L.2
Add Complement field to following primitives
MIH_MN_Group_Mnipulate.response
MIH_Net_Group_Manipulate.request
Add Complement field to following messages
MIH_MN_Group_Manipulate response
MIH_Net_Group_Manipulate request
MIH_Net_Group_Manipulate indication
