Claim Text:
1. A call reminder system for reminding users about an unanswered call by using a plurality of external electronic devices, comprising: a transceiver including a first terminal, the transceiver receiving an outside signal to generate a call signal; and a processor including a second terminal connected to the first terminal of the transmitting module, the processor receiving the call signal via the second terminal to generate a call message, generating a first reminder signal when an execute signal is not received by the processor at a first predetermined time and the call message is in compliance with a reminder condition determined by the processor, and delivering the first reminder signal to one external electronic device of the plurality of external electronic devices by the transceiver via the second terminal and the first terminal, wherein when the first reminder signal is delivered to the one external electronic device by the transceiver and the execute signal is not received by the processor in a second predetermined time, the processor generates a second reminder signal and delivers the second reminder signal to the one external electronic device by the transceiver via the second terminal and the first terminal, at each interval of a third predetermined time that the execute signal is not received, the processor continues to generate the second reminder signal, wherein the processor further generates a change signal synchronously while generating the second reminder signal, and controls the transceiver to change from one transmission method to another transmission method for delivering the second reminder signal to another external electronic device of the plurality of external electronic devices.
