With the intelligent terminals widely used in recent years

the data traffic has increased rapidly. It is necessary to pay attention to raise the utilization rate of WLAN. Base on the analysis of the reasons for low utilization rate of WLAN

a new algorithm for instant notification and real-time scheduling of WLAN is proposed in this paper. And a new AP is designed

whose broadcast channel can be detected by other communication systems. This new proposal can raise the utilization rate of WLAN

while it also provides a reference to solve the problem of collaborative work in different communication systems.
