Abstract:

Proactive pushing can exploit the spectrum underutilized during the off-peak time to push popular content files, thereby significantly improving the spectrum efficiency. Moreover, in a communication system that the virtual network operator (VNO) has to buy spectrum from the base station to conduct file transmission, proactive pushing has been recognized as a promising technology to improve the income of the VNO. However, the appropriate pushing schemes and the achievable income of the VNO are unclear yet. In this paper, joint pushing, pricing, and recommendation (JPPR) schemes are presented for cache-enabled radio access networks. We aim to investigate recommendation-based pushing policy to maximize the average income of the VNO. We establish a Markov chain model, which derives the average income of the VNO. Based on this, we formulate an optimization problem to achieve the maximum average income. We further convert the optimization problem into an equivalent linear programming problem. Moreover, a greedy algorithm is applied to solve the problem with lower computational complexity. Finally, simulation results show the significant income gains that can be achieved by JPPR schemes compared with the system without the JPPR schemes.
