Digital cellular telecommunications system (Phase 2+); Universal Mobile Telecommunications System (UMTS); End to end Quality of Service (QoS) signalling flows (3GPP TS 29.208 Version 5.8.0 Release 5)
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 relationship between SIP/SDP session level and the bearer level (RSVP and GPRS) in flows is described in 3GPP TS 24.228 [2]. The present specification adds detailed flows of Service Based Local Policy (SBLP) procedures over the Go interface and their relationship with the bearer level signalling flows over the Gn interface. The present specification also describes the mapping of QoS parameters among SDP@ UMTS QoS parameters@ and QoS authorization parameters.
