RE: stds-80220-requirements: New Material: Priority Access
Alan, Jim,
I agree that priority access should be treated as a particular instance of
QoS. In particular, if we adopt a DiffServ model, then priority access
could be a use example for the Expedited Forwarding class.
I'd also argue QoS policy should probably be applied on a per service
instance basis (e.g., PPP session), rather than on a per-device basis as
Jim's message seems to suggest. This approach allows for tiering among
high-priority services. In an emergency situation, for example, the
responding agency might want to prioritize VoIP traffic over video
surveillance traffic.

Jim-
can we say that Priority Access is a case of QOS?

As I review the requirements document, I realize that the requirement for a
priority access mechanism has been lost. Accordingly, please re-include
the following in an appropriate section:
x.x.x Priority Access Mechanism
The Air Interface shall provide priority access to authorized Mobile
Terminals.
Rationale:
In emergency situations, wireless communications systems typically are
overloaded very quickly, making communication among emergency personnel
nearly impossible. This requirement provides for support to these critical
communication situations. This is becoming a requirement in other
commercial systems and should be also carried into 802.20's air interface.
