Savings in Location Management Costs Leveraging User Statistics

Abstract

The growth in the number of users in mobile communications networks and the rise in the traffic generated by each user, are responsible for the increasing importance of Mobility Management. Within Mobility Management, the main objective of Location Management is to enable the roaming of the user in the coverage area. In this paper, we analyze the savings in Location Management costs obtained leveraging the users' statistics, in comparison with the classical strategy. In particular, we introduce two novel algorithms to obtain the β parameters (useful terms in the calculation of location update costs for different Location Management strategies), utilizing a geographical study of relative positions of the cells within the location areas. Eventually, we discuss the influence of the different network parameters on the total Location Management costs savings for both the radio interface and the fixed network part, providing useful guidelines for the optimum design of the networks.

Analysis Of the Paging Costs In Location Management for Mobile Communications Networks Leveraging The Diffusion Constant

“…In other words, SI will provide us with an indication of the granularity in the location information that the system has about the user, which will be very helpful for the network operators to optimize the Location Management procedures [2][3][4][5][6]. We have inferred the mathematical definition of the SI from the results obtained analyzing multiple cases:…”

“…Location Management is a topic of increasing importance due to the rise in the number of users in mobile communications networks [1][2][3][4][5][6]. Most of the recent research in this field has focused on the evaluation of the signalling costs involved in both location update and paging [7][8][9][10].…”

A Practical Approach to The Minimization of The Paging Costs in Location Management

“…The recent growth of users in mobile telecommunications networks has brought the need to solve difficult aspects regarding the mobility of the users and their interaction with the networks [1][2]. The proliferation of new protocols and algorithms aimed at enhancing the network capabilities and providing the user with more and better services has become a constant trend in recent years [3][4][5].…”

“…Within Mobility Management, Location Management enables the roaming of the user in the coverage area, with the main tasks involved being location update and paging [1][2]. The location update procedure consists of informing the network about every new location the mobile terminal enters, while paging is employed by the network to deliver incoming calls to the user.…”
