The disclosure is related identifying a push content frame at a transport layer and dynamically and selectively controlling a transmission path of a server push service by a server in a heterogeneous multipath transmission environment. The method may include determining whether frames are associated with the server push service when the frames are provided from an application layer to be transmitted to a user equipment, selecting at least one transmission path based on predetermined selection conditions from multiple transmission paths between the server and the user equipment, and transmitting, through the selected at least one transmission path, packetized frames associated with the server push service to the user equipment.
