scope:
The present specification shows QoS signalling flows for resource reservation to provide end-to-end QoS. The flows are used as bases of developing QoS related protocol descriptions for new and existing specifications. The following two types of flows are described:
1) flows defining the interaction of GPRS session management procedures over the Gn interface, service based local policy (SBLP) procedures over the Go interface and QoS interworking (e.g. RSVP) over the Mb interface; and
2) end-to-end flows of RSVP and GPRS bearer level.
The relationship between SIP/SDP session level and the bearer level (RSVP and GPRS) in flows showing both SIP/SDP session level and the bearer level in end-to-end flows are described in 3GPP TS 24.228 [2]. The present specification adds detailed flows involving the network interfaces Gn, Go and Mb and also further details the flows with detailed RSVP and GPRS bearer level flows not showing the SIP/SDP session level.
The present specification also describes the mapping of QoS parameters among SDP, UMTS QoS parameters, and QoS authorization parameters.
