There is always a sudden increase of customers in shopping malls on holidays, a large number of audiences in stadiums whenever there are matches, and the concert houses are packed out whenever there are big shows. Hence, sudden high traffic is usually triggered by big events mentioned above, which can result in lack of wireless network resources or traffic unbalance at each cells in the same BS coverage area, and consequently make it difficult for MSs to access to network. All these problems can be effectively solved by adopting wireless network resource intelligent dispatch system even if no more carriers are added.

      When the sudden traffic is not too high, using wireless network resources intelligent dispatch system to dispatch frequency resources between sectors between BSs or in the same BS. This not only facilitates the capacity expansion of the sectors with sudden high traffic, but also makes the traffic equivalent among sectors; during the high-traffic period, the system can also dispatch the frequency resources of surrounding traffic-unoccupied BSs to other BSs known to be deficient in resources for the purpose of capacity expansion. And the original resource assignment would be recalled after the high-traffic period. All the performances of the system mentioned above can help solve problems at low cost, flexibly distribute resources, and effectively improve the frequency utilization.
