“…Previous research work on user-tracking mechanisms in cellular networks can be found in the literature [4]- [8]. However, most of these proposals address the issue of location management strictly as an optimization problem and, in general, do not consider the impact of their implementations in commercial networks (e.g., peaks of spurious signaling traffic may flood the network during global Tracking Area reconfigurations).…”

In this paper we propose a 3GPP-compliant distributed paging mechanism over the X2 interface for allwireless Networks of Small Cells (NoS). An all-wireless NoS is a wireless mesh network that provides multi-hop connectivity amongst small cells, as well as access to functional entities in the mobile operator's core network. The standard 3GPP paging procedure has been designed with traditional macrocell scenarios in mind. This raises scalability and network congestion issues in large-scale deployments of all-wireless NoS, where paging messages need to traverse a large number of small cells in order to reach the destination mobile terminal. Our proposal aims at reducing the total number of over-the-air paging transmissions and end-to-end paging delay needed to locate a terminal in a large NoS upon arrival of an incoming voice/data connection request. The scope of the proposed scheme is limited to the NoS, thus allowing all standard procedures and interfaces towards the core network to remain untouched. In addition, new network procedures and protocol messages have been designed to ensure a seamless integration with the latest release of 3GPP Technical Specifications. Simulation results show that our scheme outperforms the standard 3GPP paging mechanism in terms of total number of over-the-air paging transmissions, number of wireless channel accesses per byte, and end-to-end paging delay.

“…For the analysis that follows, we assume that the user moves randomly and that all the location areas under study have the same area, even if this size might not be optimum (dynamic location area size strategies are proposed in [30][31][32][33][34][35]). Under these assumptions, the frequency of the location updates depends on the speed of the mobile user, v, and the surface and perimeter length of the location areas.…”

“…Assuming that a user of a mobile communications network follows a random movement and that all the location areas under study have the same area, the frequency of the location updates will depend on the speed of the mobile user [19][20][21][22][23][24][25][26], v, and the surface and perimeter length of the location areas [27][28][29][30][31][32]. Taking into account that the location update operations can take place within a same VLR (case 1, with probability 1 β ), or between two VLRs, making use of the…”

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.
