| Summary: | A virtual rea1-time service infrastructure for future wireless access，which is capable of efficiently using the idle timeslots or renewable energy distributed in the“negative time-axis”before users’ transmission requests was proposed. By using these idle timeslots，the information content in which users might be interested can be pushed to the end devices’ buffers in a multicasting manner before a user requests the content. The end devices’ algorithm which determines which content should be buffered was standardized. Hence，the base-station may locally predict what have been buffered in the users’ devices，and determine whether it should push and which content to transmit. Meanwhile，a number of key algorithms for virtual rea1-time service were proposed and analyzed，an evolution path toward virtual rea1-time service along with its major problems was also presented. Chen’s program was proposed to guide the development of the virtual rea1-time service related emerging industry and technologies. |
