The invention relates to the technical field of communication and discloses a data download management method and device. The method includes that a server determines a time greater than a target unit time corresponding to the download resources provided by the server based on the resources for downloading within per unit time, wherein the resources for downloading within the per unit time are determined based on the transaction time of all terminals; the server determines the terminals capable of downloading corresponding to the target unit time during each download period based on the resources for downloading within the target unit time and the download resources provided by the server; and the server opens the download switch of the corresponding terminal capable of downloading when the target unit time during each download period is reached. According to the invention, the problems that when a lot of terminal parameters are downloaded, the server side is easy to jam and the normal work of the server is influenced can be solved.
