For the embodiment of the present invention, the difference can holding load value in the difference of sensible load value and WLAN (wireless local area network) is exceeded in cellular network by COMPREHENSIVE CALCULATING community, can be embodied as while cellular network carries out shunting, ensure the situation not occurring overload in WLAN (wireless local area network).
405, each carrying out adding up is consumed each shunting terminal that cell power is community than terminal configuration corresponding respectively by shunt controller.
For the embodiment of the present invention, it is larger by each is consumed cell power, and the terminal configuration that sum is greater than or equal to preset threshold value is each shunting terminal of community, can realize the load value according to preset threshold value decline cellular network, and reduce the quantity of shunting terminal.In embodiments of the present invention, be fixed value owing to shunting the ratio causing Consumer's Experience to decline, therefore reduce the quantity of shunting terminal, the possibility that Consumer's Experience declines can be reduced, and then can Consumer's Experience be improved.
