The group is mandated to define a common set
of Service Class Names, SFIDs, and QoS Parameter Sets to be common across
different Operators. Global basic Service Flows are necessary to
facilitate foreign network soft-handovers (persistent service flows) in mobile
networks. In the current standard, foreign networks have no way to
recognize and/or negotiate Service Flow parameters during a handover.
Indeed, it is entirely possible for two different Operators to implement the
same Service Class Name with differing QoS Parameter Sets. Again, this
dilemma provides no performance impediment to fixed wireless devices that do
not traverse multiple Operator networks. It is only a problem in mobile
networks. Providing an Annex of Recommended Global Service Flow
definitions would remedy this problem. It is expected that our product
would be useful for the emerging IEEE
P802 Handoff Executive Committee Study Group (ECSG).
