Abstract: A collaborative mechanism that comprehensively considers business needs, user experience, terminal capability, air interface capability, and network status is proposed. This mechanism uses intelligent means to predict the user experience expectation of a multi-layer target network, and realize the optimal matching between users and the network. The network is arranged according to the strategy with the optimal user experience and the highest network efficiency, which avoids many problems brought by the traditional single collaboration mechanism. The high and low frequency coordination mechanism and strategy of realizing both user experience and network efficiency are of great theoretical significance for the future organic integration of high and lowfrequency multi-layer networks.
