A method for performing seamless transmission control for an electronic device, wherein the method comprises the steps of: sending a request frame carrying a fragment identification, ID, to trigger a responder in a wireless network system to initiate a transmission corresponding to the fragment ID, wherein the fragment ID indicates a beginning of a portion within a plurality of fragments of data; and receiving at least one response frame from the responder, wherein the portion within the plurality of fragments of the data is carried by the at least one response frame, characterized in that the step of sending the request frame carrying the fragment ID to trigger the responder in the wireless network system to initiate the transmission corresponding to the fragment ID comprises: inserting the fragment ID into a specific field of a Generic Advertisement Service, GAS, initial request frame; and utilizing the GAS initial request frame carrying the fragment ID as the request frame, wherein within the plurality of fragments of the data being sent from the responder to the electronic device, a 1st fragment through to an Nth fragment are successfully received by the electronic device before the request frame carrying the fragment ID is sent; and the method further comprises: setting the fragment ID to be that of an (N + 1) th fragment within the plurality of fragments, and wherein the portion within the plurality of fragments of the data comprises the (N + 1) th fragment through to a last fragment within the plurality of fragments. sending a request frame carrying a fragment identification, ID, to trigger a responder in a wireless network system to initiate a transmission corresponding to the fragment ID, wherein the fragment ID indicates a beginning of a portion within a plurality of fragments of data; and receiving at least one response frame from the responder, wherein the portion within the plurality of fragments of the data is carried by the at least one response frame, characterized in that the step of sending the request frame carrying the fragment ID to trigger the responder in the wireless network system to initiate the transmission corresponding to the fragment ID comprises: inserting the fragment ID into a specific field of a Generic Advertisement Service, GAS, initial request frame; and utilizing the GAS initial request frame carrying the fragment ID as the request frame, wherein within the plurality of fragments of the data being sent from the responder to the electronic device, a 1st fragment through to an Nth fragment are successfully received by the electronic device before the request frame carrying the fragment ID is sent; and the method further comprises: setting the fragment ID to be that of an (N + 1) th fragment within the plurality of fragments, and wherein the portion within the plurality of fragments of the data comprises the (N + 1) th fragment through to a last fragment within the plurality of fragments. inserting the fragment ID into a specific field of a Generic Advertisement Service, GAS, initial request frame; and utilizing the GAS initial request frame carrying the fragment ID as the request frame, wherein within the plurality of fragments of the data being sent from the responder to the electronic device, a 1st fragment through to an Nth fragment are successfully received by the electronic device before the request frame carrying the fragment ID is sent; and the method further comprises: setting the fragment ID to be that of an (N + 1) th fragment within the plurality of fragments, and wherein the portion within the plurality of fragments of the data comprises the (N + 1) th fragment through to a last fragment within the plurality of fragments.
