Intelligent cellular network load balancing using a cooperative negotiation approach

In this paper, we investigate a novel distributed load balance scheme for cellular networks, which intelligently changes cellular coverage according to the geographic traffic distribution in real time. The performance of the whole cellular network can be improved by contracting the base station antenna pattern around a traffic "hot spot" and expanding adjacent cells\´ coverage to fill in the loss. A cooperative negotiation approach with semi-smart antennas for cellular network coverage control is described in this paper. By the use of negotiations between adjacent base stations, optimum local coverage agreements can be achieved in the context of the whole cellular network. Results showing the advantage of this technique are also presented.
