Communication Model - 
    

October 18, 2005



      

If a UE is connected to a single L2 link can we have a MIH 
        

PoS in PoA 
    

and possibly another L3 MIH PoS somewhere else in the network?
If a UE is connected to multiple L2 links how is a MIH PoS at
L3 associated with a network w.r.t above restriction?
        

My thought was that the UE may not receive CS from multiple MIH
      

entities
    

and UE cannot decide on the info authenticity if there were multiple 
sources of IS. I agree with you that there is a possibiliy 
      

that these 
    

MIH services can be shared between L3 and L2 MIH entities. 
      

But it must 
    

be in a way that they are not conflicting in the offered services. I 
think we should capture this. I was thinking about stating 
      

generically 
    

that multiple MIH PoS can provide partial MIH services (IS, 
      

ES and CS) 
    

but the provided (partial) services in such a way they are not 
conflicting with other services offered by other MIH PoS.  How does
      

this
    

sound?
      

[Vivek G Gupta]
...not very convincing.
It should be left to UE and MIH enabled network entities (MIH 
PoS) to discover each other, decide and negotiate an 
association. Given that there can well be multiple instances 
of such associations and it would be up to the UE to select 
and sign up for appropriate services for each association and 
also possibly deal with multiple instances of such 
associations and individual services.
Maybe this needs to be better explained in doc. I don't have 
any good practical scenarios though.

    

Srini)) I need to understand you better. My question is - why would a UE
have two IS providers (MIH PoS) in the same network providing same
information?  Why would the UE receive the same CS from two different
MIH PoS? If so, which one is authentic? 

     Subir> Why do we want to restrict this?  Our position should be we don't care if two IS providers
                 want to be in the at same place and  provide the same info. This will possibly depend upon
                 their business model, pricing  etc. It is  upto the UE and the network operator to choose
                 the right one and most likely it will be governed  by the policy .
