Target entity: Dual Radio Voice Call Continuity Context triple: [SRVCC, contrastsWith, Dual Radio Voice Call Continuity]
-
A.
SRVCC
SRVCC (Single Radio Voice Call Continuity) is a mobile network feature that enables seamless handover of ongoing voice calls from LTE or VoLTE to legacy circuit-switched networks like 2G or 3G.
-
B.
Interrogating Call Session Control Function
Interrogating Call Session Control Function is a core IMS network element that serves as the initial contact point for SIP signaling, handling routing, registration queries, and interaction with subscriber databases in IP-based telephony systems.
-
C.
CSFB (Circuit Switched Fallback)
CSFB (Circuit Switched Fallback) is a mobile network feature that allows LTE devices to temporarily switch to a legacy 2G/3G circuit-switched network to handle voice calls and SMS.
-
D.
VoLTE
VoLTE (Voice over LTE) is a technology that enables high-quality voice calls to be transmitted as data over 4G LTE networks instead of traditional circuit-switched voice channels.
-
E.
GSM EDGE Radio Access Network
GSM EDGE Radio Access Network (GERAN) is a 2G/2.5G mobile telecommunications radio access technology that enhances GSM networks with higher data rates using EDGE modulation.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
