Various embodiments of the present invention relate to an apparatus for rearranging protocols in an electronic device, and an operating method therefor. The electronic device comprises: a transceiver unit; and at least one processor functionally coupled to the transceiver unit, wherein the at least one processor is configured to: control an operation of receiving information on a first protocol list including a plurality of protocols from a server; identify, for each of the plurality of protocols, position information of a radiography apparatus which captures an image, and the type of detection unit which detects a beam generated from the radiophotography apparatus; rearrange the order of the plurality of protocols on the basis of at least one of the position information of the radiography apparatus and the type of detection unit, so as to generate a second protocol list; and control an operation of transmitting information on the second protocol list to the radiography apparatus.
