Phrase: Dual Radio Voice Call Continuity | Statement: [SRVCC, contrastsWith, Dual Radio Voice Call Continuity]

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.
