An operating method of an electronic device, the method comprising: determining whether a received message is confirmed within a first preset time; determining whether a contact number of a sender electronic device is a preset contact number; and if the received message is confirmed within the first preset time, determining whether a user generated response message to the received message is transmitted to the sender electronic device within a second preset time; wherein if the received message is not confirmed within the first preset time or if the user generated response message to the received message is not transmitted to the sender electronic device within the second preset time, and if the contact number of the sender electronic device is a preset contact number, the method further comprises sending (1008, 1012) an automatic response message to the sender electronic device corresponding to a preset automatic response message status; wherein confirming the received message comprises the user interacting with the electronic device upon receipt of the received message; wherein the second preset time is longer than the first preset time; and wherein sending (1008, 1012) the automatic response message to the sender electronic device comprises: determining the preset automatic response message status; when the preset automatic response message status is set for sending a first message, determining a current status to generate the first message; generating the first message corresponding to the determined current status; and sending the generated first message to the sender electronic device. determining whether a received message is confirmed within a first preset time; determining whether a contact number of a sender electronic device is a preset contact number; and if the received message is confirmed within the first preset time, determining whether a user generated response message to the received message is transmitted to the sender electronic device within a second preset time; wherein if the received message is not confirmed within the first preset time or if the user generated response message to the received message is not transmitted to the sender electronic device within the second preset time, and if the contact number of the sender electronic device is a preset contact number, the method further comprises sending (1008, 1012) an automatic response message to the sender electronic device corresponding to a preset automatic response message status; wherein confirming the received message comprises the user interacting with the electronic device upon receipt of the received message; wherein the second preset time is longer than the first preset time; and wherein sending (1008, 1012) the automatic response message to the sender electronic device comprises: determining the preset automatic response message status; when the preset automatic response message status is set for sending a first message, determining a current status to generate the first message; generating the first message corresponding to the determined current status; and sending the generated first message to the sender electronic device. determining the preset automatic response message status; when the preset automatic response message status is set for sending a first message, determining a current status to generate the first message; generating the first message corresponding to the determined current status; and sending the generated first message to the sender electronic device.
