In order to motivate Internet Service Providers (ISPs) to deploy in-network caching, we need to develop a new pricing mechanism among ISPs, Content Provider (CP), and users. The existing pricing mechanism of Information Centric Networks (ICN) mainly considers paid content, but more practically, there is more free content on the network. Therefore, based on the free content, we first propose one pricing and caching mechanism with advertisers’ participation in ICN and use game theory to solve our model. The analysis shows that participants in the network have the best advertising charging strategy, content caching strategy, and the best profit point. The simulation results show that the model can maximize the participants’ profits in the competition process. At the same time, it can be seen that this model is more practical and more profitable than the traditional charging model, so it can achieve the purpose of motivating ISPs to deploy in-network caching.
