The invention discloses a method for improving time delay performance of 5G slice and WiFi (Wireless Fidelity) hybrid networking in a substation scene. The method comprises the following steps: S1, building an M/G/1 queuing model of an LTE-U (Long Term Evolution-Units) and WiFi (Wireless Fidelity) hybrid networking system in a 5G heterogeneous wireless slice network; s2, calculating the average packet delay of the LTE-U system; s3, calculating the average packet delay of the WIFI system; and S4: applying the average packet delay of the LTE-U system and the average packet delay of the WIFI system, and improving the delay performance of the hybrid networking system in a non-registered frequency band based on an intelligent blank subframe configuration algorithm of Q learning in reinforcement learning. According to the method provided by the invention, a relatively reasonable blank subframe configuration strategy can be generated for the LTE-U under different load conditions of multiple services, and the method
