Methods and apparatuses are provided for connecting with an external device. A current status of an electronic device is determined when wireless communication with at least one external device is disconnected. A preset time interval corresponding to the current status is determined. An attempt is made to reconnect with the at least one external device based on the preset time interval.

A method and a portable device for supporting an adaptive data communication control are provided. The device includes a memory unit, a control unit, and a radio frequency unit. The memory unit stores a table that contains data communication setting information corresponding to each service operator network. The control unit performs a Public Land Mobile Network (PLMN) selection after entering into a service area of specific service operator network, and receives Mobile Country Code/Mobile Network Code (MCC/MNC) information from the specific service operator network while the PLMN selection is being performed. The control unit extracts the data communication setting information corresponding to the MCC/MNC information from the table, and establishes a data communication connection with the specific service operator network according to the extracted data communication setting information. The radio frequency unit performs the established data communication with the specific service operator network under the control of the control unit.

The present invention discloses a winch and an autonomous mobile apparatus including the winch. The winch can include: a driving motor; a drum driving axle configured to be rotated the driving motor; a wire drum configured to be rotated by the drum driving axle; a roller driving axle arranged to be parallel to the drum driving axle and configured to be rotated in different direction from that of the drum driving axle by the driving motor; a roller connected with the roller driving axle and configured to support a wire wound on or unwound from the wire drum; and a one way clutch installed in the roller driving axle in such a way that a driving force transferred to the roller by the roller driving axle is cut off when the wire drum rotates in a direction of winding the wire. The roller can be transferred with a driving force by the roller driving axle and can be rotated in such a way that a wire placed between the wire drum and the roller maintains tension when the wire drum rotates in a direction of unwinding the wire.
