  Increasing wireless cellular networks capacity is one of the major challenges
for the coming years, especially if we consider the annual doubling of mobile
user traffic. Towards that and thanks to the fact that a significant amount of
mobile data is indeed delay tolerable, in this paper, we suggest embedding the
delayed offloading of some user traffic to be a part of future wireless
cellular networks. To accomplish this, user delayed files will be offloaded
using ultra-high speed Millimeter Wave (Mm-W) Gates. The Mm-W Gate, which will
be distributed inside the Macro basestation (BS) area, consists of number of
Mm-W Access Points (APs) controlled by a local coordinator installed inside the
Gate. To effectively manage the delayed offloading mechanism, utilizing the
concept of User/Control (U/C) data splitting, the Gates coordinators and the
Macro BS are connected to the Cloud Radio Access Network (C-RAN) through
optical fiber links. Also, files offloading organizer software is used by the
User Equipment (UE). A novel weighted proportional fairness (WPF) user
scheduling algorithm is proposed to maximize the Gate Offloading Efficiency
(GOFE) with maintaining long term fairness among the different mobility users
pass through the Gate. If the Gate is properly designed and the files delay
deadlines are properly set; near 100% GOFE with average reduction of 99.7% in
UE energy consumption can be obtained, in time the user just passes through the
Gate.
