The present invention provides a base station resource sharing system and method, which comprises a plurality of base stations connected to each other to form a cloud base station, and puts resources of each base station into the same resource pool, and implements each base station in a resource pool and dynamic resource scheduling manner. Resource Sharing. After the resource is shared, even if one of the base stations bursts a large number of users, exceeding the upper limit of the base station user, the base station can continue to accept the user and provide the service as long as there are remaining resources in the resource pool. The invention dynamically allocates resources by means of resource pool sharing, reduces network congestion, improves utilization efficiency of base station resources, expands user capacity of a traditional base station into user capacity of the entire cloud base station, improves base station user capacity, and can wirelessly according to service requirements. The network resources are dynamically deployed to effectively cope with the tidal effect and significantly improve the quality of the service. The above description shows and describes a preferred embodiment of the present invention, but as described above, it should be understood that the present invention is not limited to the forms disclosed herein, and should not be construed as Other combinations, modifications, and environments are possible and can be modified by the teachings or related art or knowledge within the scope of the inventive concept described herein. All changes and modifications made by those skilled in the art are intended to be within the scope of the appended claims. INDUSTRIAL APPLICABILITY The technical solution of the present invention dynamically allocates resources by means of resource pool sharing, reduces network congestion, improves utilization efficiency of base station resources, expands user capacity of a conventional base station into user capacity of the entire cloud base station, improves base station user capacity, and can Dynamically deploy wireless network resources according to business needs, effectively coping with the tidal effect and significantly improving service quality.
