The download-proxy and the download-management-platform deployed on custom oriented terminal compose the mobile phone’s download manager

which accepts the user’s download requests and communicates with the mobile operator business support system interactively

downloads（also support to upload） and manages the user’s requests-data at night when the network idle

the custom can get the datum at the next day

those random and disordered user’s needs can become orderly and controllable business process

then some network flow can be splited to the night time through this technique.
