Abstract:
1. A computer usable program product comprising a computer usable storage device including computer usable code for mobile data transmission, the computer usable code comprising: computer usable code for receiving a request for data from a mobile device; computer usable code for determining, using a processor and a memory, whether a data transmission over a mobile data communication network in response to the request can be delayed, forming a time-shifting determination; computer usable code for determining, responsive to the time-shifting determination being affirmative, a delayed schedule for the data transmission in response to the request such that the data transmission is completed by a deadline; and computer usable code for transmitting over the mobile data communication network the data according to the delayed schedule, wherein the computer usable code for determining the delayed schedule further comprises: computer usable code for receiving a plurality of requests from a corresponding plurality of mobile devices, wherein each request in the plurality of requests has a corresponding deadline, and wherein the request is one of the plurality of requests and the deadline is one of the plurality of deadlines; computer usable code for arranging the plurality of requests in an order of shortest deadline to longest deadline; computer usable code for determining a pattern of movement (mobility pattern) of the mobile device during a period; computer usable code for determining a probability density function (PDF) of channel quality in the mobile data communication network over the period, wherein the PDF of channel quality is determined using historical channel quality data collected along the mobility patterns during the period; computer usable code for computing a signal threshold using the channel quality PDF and the mobility pattern, such that transmitting the data only when signal quality to the mobile device exceeds the signal threshold satisfies the deadline; computer usable code for identifying a time slot when the signal quality to the mobile device exceeds the signal threshold, wherein the delayed schedule is based on the identified time slot, and wherein the data is transmitted using the time slot; computer usable code for scheduling to transmit second data in response to a second request in the plurality of requests in a second time slot.
