Abstract
A user equipment (UE), a method and a communication apparatus are provided. The UE includes a first communication circuit that receives a notification, a processor, and a memory unit that is operatively connected to the processor and includes instructions. The instructions, when being executed, cause the processor to execute a method. In the method, it is determined that the notification indicates that an incoming call was directed to the UE during a preset time period. It is identified that the UE did not receive the incoming call during the preset time period based on: an identification that the incoming call was not forwarded to another device; and an identification that, during the preset time period, the UE was not in a call handling mode in which the UE does not receive incoming call. A recovery option is performed based on identification that the UE did not receive the incoming call.
