[0051] The invention adopts the K-means clustering algorithm to perform clustering processing on massive network user mobile data, and realizes the determination and division of hotspot areas. Then a PCI allocation method based on the maximum priority coloring algorithm is proposed. This method can quickly and effectively allocate and multiplex the small cell base stations in hotspots, while reducing the probability of PCI conflict and confusion, and improving the hotspots. The user’s network service quality.
[0052] The present invention adopts the following technical solutions and implementation steps.
[0053] Step 1. Build a deployment model of cellular network base stations. Macro cellular network base stations use the traditional Wrap-Around deployment model, such as figure 1 As shown, the scene is 1500×1500m 2 The macro cellular network base station simulation deployment diagram under. For the small cell network, the present invention uses the homogeneous Poisson point pro...
