A network sharing method, comprising: acquiring access user information and bandwidth occupancy information of network sharing operators, and determining service execution sequence information of access users according to the access user information, the access user information comprising access user requested service information and attached operator information, the access user requested service information referring to attribute information of requested services, including a service delay, a service Allocation and Retention Priority, ARP, and a service priority; correcting the bandwidth occupancy information of the network sharing operators using a bandwidth correction value of a previous scheduling opportunity, wherein the bandwidth correction value contains two levels of information, a first information that indicates whether remaining bandwidth resources, which are obtained after bandwidths of a certain operator are not completely allocated in the previous scheduling opportunity within a certain scheduling opportunity, are allowed to be used by other operators; and a second information that refers a difference between bandwidth resources actually occupied by a certain operator and an upper limit of available bandwidths of the certain operator under the condition that remaining bandwidth resources are allowed to be mutually occupied among operators; allocating bandwidth resources according to the service execution sequence information of the access users and the corrected bandwidth occupancy information of the network sharing operators; and collecting statistics on actual bandwidth resource information, and performing service balancing between base stations according to the statistical actual bandwidth resource information, or determining a new bandwidth correction value for correction of the bandwidth occupancy information of the network sharing operators within a next scheduling opportunity. acquiring access user information and bandwidth occupancy information of network sharing operators, and determining service execution sequence information of access users according to the access user information, the access user information comprising access user requested service information and attached operator information, the access user requested service information referring to attribute information of requested services, including a service delay, a service Allocation and Retention Priority, ARP, and a service priority; correcting the bandwidth occupancy information of the network sharing operators using a bandwidth correction value of a previous scheduling opportunity, wherein the bandwidth correction value contains two levels of information, a first information that indicates whether remaining bandwidth resources, which are obtained after bandwidths of a certain operator are not completely allocated in the previous scheduling opportunity within a certain scheduling opportunity, are allowed to be used by other operators; and a second information that refers a difference between bandwidth resources actually occupied by a certain operator and an upper limit of available bandwidths of the certain operator under the condition that remaining bandwidth resources are allowed to be mutually occupied among operators; allocating bandwidth resources according to the service execution sequence information of the access users and the corrected bandwidth occupancy information of the network sharing operators; and collecting statistics on actual bandwidth resource information, and performing service balancing between base stations according to the statistical actual bandwidth resource information, or determining a new bandwidth correction value for correction of the bandwidth occupancy information of the network sharing operators within a next scheduling opportunity.
