A method for realizing communication load balance, comprising: setting, by a load monitoring subsystem, a basis value of a communication load of a cell, in a Base Transceiver Station, BTS, monitoring communication loads of cells, in said BTS, and setting charging solutions corresponding to the cells (S201, S401), by obtaining a charging solution corresponding to the cell by comparing the basis value with the communication load of the cell at present and/or that in previous period of time, wherein the charging solutions are charge discounts of basis charges of various value added services in each cell; acquiring, by a load control subsystem, the charging solutions corresponding to the cells that the load monitoring subsystem obtains by calculation through monitoring the communication loads of the cells, and storing the charging solutions in a charging solution information database (S202, S402), the load control subsystem being connected with the load monitoring subsystem, the charging solution information database being arranged in the load control subsystem, the load control subsystem bearing a load control service, the load control subsystem being coupled to a core network and a value added service subsystem; when a user triggers a value added service via the core network (S203, S404), triggering, by a Mobile Switching Center, MSC, in the core network, the load control service; reading, by the load control subsystem from the charging solution information database, a charging solution corresponding to a cell where the user is currently located (S204, S409), and forwarding a charge control signaling containing the charging solution to the value added service subsystem for bearing the value added service; and receiving, by the value added service subsystem, the charge control signaling forwarded by the load control subsystem, and processing the value added service according to the charging solution received, by: determining whether the value added service is allowed to run, according to the charging solution included in the charge control signaling, in combination with at least one of a service provisioning state, a charge balance, or a call attribute; if the value added service is allowed to run, notifying a service control module in the load control subsystem to run the value added service via the MSC of the core network; if the value added service is not allowed to run, notifying a service control module in the load control subsystem to release the value added service via the MSC of the core network. setting, by a load monitoring subsystem, a basis value of a communication load of a cell, in a Base Transceiver Station, BTS, monitoring communication loads of cells, in said BTS, and setting charging solutions corresponding to the cells (S201, S401), by obtaining a charging solution corresponding to the cell by comparing the basis value with the communication load of the cell at present and/or that in previous period of time, wherein the charging solutions are charge discounts of basis charges of various value added services in each cell;
