SRVCC (Single Radio Voice Call Continuity) is a feature in telecommunications that allows a voice call to be maintained seamlessly when a user moves between different network types, such as from LTE (Long-Term Evolution) to 2G or 3G networks. SRVCC ensures that ongoing voice calls do not drop when the user transitions between network technologies, providing a smoother and more reliable voice experience.
What is SRVCC in Telecom?
In telecom, SRVCC (Single Radio Voice Call Continuity) is a mechanism designed to support uninterrupted voice calls as users move between LTE and legacy networks, such as 2G or 3G. This capability is essential for maintaining call continuity when a user switches from a high-speed LTE network to a lower-speed 2G or 3G network, ensuring that the voice call remains active without interruptions.
CSFB (Circuit-Switched Fall Back) is a technique used in mobile networks to handle voice calls in LTE (Long-Term Evolution) environments. When a user initiates a voice call on an LTE network, the network may fall back to a circuit-switched network (such as 2G or 3G) to complete the call. CSFB allows LTE networks to support voice services by temporarily switching to a legacy network that can handle circuit-switched calls.
CSFB (Circuit-Switched Fall Back) in 5G operates similarly to its function in LTE environments. It provides a mechanism for handling voice calls by falling back to a 2G or 3G network when necessary, as 5G networks primarily focus on data services and do not natively support circuit-switched voice calls. This ensures that voice services are still available to users while using 5G for data services.
CSFB stands for Circuit-Switched Fall Back. It is a method used in mobile networks to provide voice services by temporarily switching from a packet-switched network (like LTE) to a circuit-switched network (like 2G or 3G) to handle voice calls. This technique allows networks to support voice communication even when the primary network does not natively handle circuit-switched calls.
