Figure 9-2 – Enriched call decomposition

1) User A MUE1 sends a SIP SC1 invite (SDP audio/video session) to SCF1 to create the SC1 component.
2) SCF1 forwards the SIP SC1 invite message of SC-1 to MAS-F.
3)-4) MAS-F obtains related information (such as the equipment that the messages come from, the
applications that the messages belong to, etc.) from MUP-FE; MAS-F identifies that SC-1 can be
decomposed for User B, then decomposes SC1 as SC2 and SC3.
