Abstract:
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). According to an embodiment of the present disclosure, a circuit switched fallback (CSFB) method is provided. The method comprising: receiving, by a first base station, a user equipment (UE) context modification request message from a mobility management entity (MME), wherein the UE context modification request message includes a CSFB indicator; receiving, by the first base station, a radio link failure (RLF) indication message from a second base station; and determining, by the first base station, whether to trigger a handover procedure.
