Location management is one of the most important issues in the design of future cellular systems. It consists of two basic operations, location update and paging. The paging operation is dependent on the corresponding location update operation. The time-based, movement-based, and distance-based location update schemes are three of the most popular dynamic location update schemes. It has been shown that the distance-based scheme is more efficient than the movement-based. However, the distance between two cells is difficult to obtain. In this paper, we have proposed a coordinate system, which can be used to systematically assign IDs to the cells in a cellular system. With this cell ID assignment scheme, the distance between any two cells can be computed easily. Based on our distance computation scheme, a speed adaptive location update scheme has been presented. It has been shown that our speed adaptive location update scheme is a generalization of both time-based and distance-based schemes.
