Technical Specification Group Services and System Aspects;
End-to-end Quality of Service (QoS) concept and architecture
(Release 6)
This time we are talking about GPRS and end-to-end. Much more complete than the previous. I clarifies that the AF can be the CSCF. The Gq and Go Interface are also described. It also esplains that both DS (differentiated services) and RSVP can be used to guarantee QoS in the IP core network and remote link. It assumes that since GPRS is used in the local link, the PDP flow already has QoS guarantees.
The diffserv is already supported in WMM, so it seems the more straight-forward approach.
