RE: 802.21 Neigbor Report



Mathieu,

Thee are good issues which I wanted to discuss as part of this
presentation but could not at the Garden Grove meeting due to lack of
time slots.
Some comments below.

Subject: 802.21 Neigbor Report
 
Hi Vivek and all,

I have some questions regarding the conclusion of your presentation
about Neighbor Reports. It says:

1) Media Independent Neighbor Reports can only support Static
capabilities of different PoAs
>> That means you want to use Information Service for Neighbor Reports,
because only Static Info can be embeded
In IS messages ??
[Vivek G Gupta] 
Yes, since the IS can only support static type of info, essentially
Neighbor Reports that are part of 802.21 IS and inform the client
devices about different PoAs re essentially restricted to more of static
type of information.



2) Access Network specific Neighbour Reports can provide insight into
more Dynamic information
Statistics, Resource levels, State information
>> If an entity in the network (an MME for instance) has to retrieve
dynamic info about a particular UE's neighbor PoAs, Access Network
specific Neighbour Reports won't make it to the MME, because
transmission of such reports is inherently limited to the access network
broadcast domain. Some means of transporting these Access Network
specific neighbor reports to the MME are then needed. Wouldn't it be the
task of 802.21 to specify such a means ?
[Vivek G Gupta] 
I am not sure. 
Seems like MME may be at different locations for different networks and
that may cause difficulty in standardizing the transport. In some ways
this could also depend on specific network architecture. 


If we don't specify this, don't we restrain the possible location of an
MME to the Access Network ?
[Vivek G Gupta] 
You could have some entity in the access network that could relay this
information to MME etc. You could use the L3 protocol for IS as a
starting point.


I know we have discussed that before, but as you made this new
presentation, I take the opportunity to solve this issue.
[Vivek G Gupta] 
We are glad you raised this and your comments are welcome.
Best Regards
-Vivek
