The objective of the feasibility study is to investigate a solution for supporting Single Radio Voice Call Continuity
(SRVCC) from 3GPP UTRAN/GERAN CS access to 3GPP E-UTRAN/HSPA access, for voice call initiated in
LTE/HSPA access and previously handed over to UTRAN/GERAN CS access, as well as for the voice call directly
initiated in UTRAN/GERAN CS access.
