Interface of MIH with Upper layers
Hello 802.21 Folks,
Another issue which seems to be emerging is the definition of MIH_L3_SAP
or MIH_User_SAP, etc. as some have referred to in their proposals.
The question is should this SAP be defined in normative sense within
802.21?
This SAP allows higher layer (typically L3) entities to interface with
MIH. This layer to layer communication in a local stack typically
depends on specific OS, driver models in that OS and other requirements.
So what would be the goal and benefits of defining this interface (SAP)
in normative sense? Who would be the consumers of this and how can we
drive/enforce this in normative sense?
Folks have mentioned interoperability and other benefits around this.
But it would be good to get a clear understanding around this as well. I
am not sure if OS abstraction is the goal around some of this(?)
Comments/Thoughts?
BR,
