In this paper, a new static traffic-based location area design scheme named ETB-LAD (enhanced TB-LAD) for wireless systems is proposed. This scheme is an enhancement on the previously published TB-LAD scheme. In the new method, the expected intercell movement patterns of mobiles are determined and then the cells are partitioned into location areas (LAs) by applying the new traffic-based cell grouping algorithm, which has two goals. First, the cell pairs with higher intercell mobile traffic are grouped into the same LA. Second, the LAs, in which the neighbour cells have higher intercell traffic, allowed to include more cells than the LAs, where the intercell traffic is low. The aim of the scheme is to decrement the inter-LA movements, which create registration traffic. Experimental results show that the new scheme performs better than the TB-LAD and proximity based location area design (PB-LAD) schemes in the sense that it can reduce the location updates.
