Abstract
The present invention provides a multi-iteration based channel assignment optimization method and a channel assignment optimization apparatus. The channel assignment optimization method comprises a channel assignment optimization path searching phase and a channel switching phase. During the channel assignment optimization path searching phase, the IBS negotiates with neighboring base stations so as to detect a channel assignment optimization path through multiple iterations. Merely after successfully detecting a feasible channel assignment optimization path, IBS and its neighboring base stations initiate a channel switching process, such that useless channel switching may be avoided. Besides, in order to avoid the problem of incapability of timely convergence during the iteration process, a threshold of iteration times is preset. Once the current iteration times is greater than the threshold, the channel assignment optimization path searching process on the current channel will exit and then the process switches to other channel to detect another path.
