First network equipment, for obtaining the corresponding operation data of M network, M is the positive integer more than or equal to 1;Utilize the M
The corresponding operation data of a network, is calculated predicted load of each cell in the first period in the M network;Root
According to the predicted load and preset load balancing, each cell and Target cell in the M network are determined
The adjusting parameter of each cell and its corresponding Target cell is sent to corresponding second network equipment by adjusting parameter;
Wherein, the adjusting parameter includes: switching, reselecting parameters, and use in the range of each cell is by each cell
Family terminal is to the time for switching to source cell for when external migration, postponing the user terminal of the Target cell;
Second network equipment, for receiving the corresponding Target cell of each cell and adjusting parameter of self-management.
