RESOURCE OPTIMIZATION IN MOBILE COMMUNICATION NETWORKS WITH USER PROFILE -BASED ALGORITHMS

In mobile communications networks, Location Management enables the roaming of the user in the coverage area. The employment of the call and mobility patterns of the user can help minimize the signaling costs involved in Location Management, and optimize the available radio resources. In this paper, we carry out an exhaustive analysis of the location update costs involved in a user profile-based Location Management algorithm, and compare its performance with the classical strategy of static location areas. As original contributions, we introduce two new algorithms to obtain the β parameters, useful for the calculation of the Location Management signaling costs. Making use of these new algorithms, we show the convenience of the application of user profile-based strategies for Location Management in order to optimize the available radio resources, and we obtain practical guidelines for the optimum design of mobile communications networks.
